单选题Success, it is often said, has many fathers--and one of the many fathers of computing, that most successful of industries, was Charles Babbage, a 19th-century British mathematician. Exasperated by errors in the mathematical tables that were widely used as calculation aids at the time, Babbage dreamed of building a mechanical engine that could produce flawless tables automatically. But his attempts to make such a machine in the 1920s failed, and the significance of his work was only rediscovered this century. Next year, at last, the first set of printed tables should emerge from a calculating "difference engine" built to Babbage's design. Babbage will have been vindicated. But the realization of his dream will also underscore the extent to which he was a man born ahead of his time. The effort to prove that Babbage's designs were logically and practically sound began in 1985, when a team of researchers at the Science Museum in London set out to build a difference engine in time for the 200th anniversary of Babbage's birth in 1992. The team, led by the museum's curator of computing, Doron Swade, constructed a monstrous device of bronze, iron and steel. It was 11 feet long, seven feet tall, weighed three tons, cost around $500 000 and took a year to piece together. And it worked perfectly, cranking out successive values of seventh-order polynomial equations to :31 significant figures. But it was incomplete. To save money, an entire section of the machine, the printer, was omitted. To Babbage, the printer was a vital part of design. Even if the engine produced the correct answers, there was still the risk that a transcription or typesetting error would result in the finished mathematical tables being inaccurate. The only way to guarantee error-free tables was to automate the printing process as well. So his plans included specifications for a printer almost as complicated as the calculating engine itself, with adjustable margins, two separate fonts, and the ability to print in two, three or four columns. In January, after years of searching for a sponsor for the printer, the Science Museum announced that a backer had been found. Nathan Myhrvold, the chief technology officer at Microsoft, agreed to pay for its construction (which is expected to cost $373 000 with one Proviso: that the Science Museum team would build him an identical calculating engine and printer to decorate his new home on Lake Washington, near Seattle). Construction of the printer will begin--in full view of the public--at the Science Museum later this month. The full machine will be completed next year. It is a nice irony that Babbage's plans should be realized only thanks to an infusion of cash from a man who got rich in the computer revolution that Babbage helped to foment. More striking still, even using 20th-century manufacturing technology the engine will have cost over $830 000 to build. Allowing for inflation, this is roughly a third of what it might have cost to build in Babbage's day-in contrast to the cost of electronic-computer technology, which halves in price every 18 months. That suggests that, even had Babbage succeeded, a Victorian computer revolution based on mechanical technology would not necessarily have followed.
单选题The earliest immigrants to North America found Indians already living there. The Indians numbered about 500,000 at that time. Their society was a primitive society, but they lived peacefully and welcomed the white strangers to the land. However, these early immigrants from Europe didn"t want to share the land with the natives. They killed off many of the Indians, seized their land or pushed them off to lands farther away. Today the Indians, not more than half a million, live in poverty and misery on the land on which they were once masters.
The earliest immigrants were the Spanish, who settled in the southern part of what is now the US. The next large group were the English, after the English came the French, Dutch, Irish, Germans, and other nationality groups, mostly European.
Another early group to arrive were the Negroes. But they were brought in as slaves from Africa. They didn"t win freedom till generations later.
单选题The sound from the wastebasket was made by ______.
单选题We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them. But we have realized only recently that the identity of each sex is not so easy to pin down, and that definitions evolve in accordance with different types of culture known to us, that is, scientific discoveries and ideological revolutions. Our nature is not considered as immutable, either socially or biologically. As we approach the beginning of the 21st century, the substantial progress made in biology and genetics is radically challenging the roles, responsibilities and specific characteristics attributed to each sex, and yet, scarcely twenty years ago, these were thought to be "beyond dispute". We can safely say, with a few minor exceptions, that the definition of the sexes and their respective functions remained unchanged in the West from the beginning of the 19th century to the 1960s. The role distinction, raised in some cases to the status of uncompromising dualism on a strongly hierarchical model, lasted throughout this period, appealing for its justification to nature, religion and customs alleged to have existed since the dawn of time. The woman bore children and took care of the home. The man set out to conquer the world and was responsible for the survival of his family, by satisfying their needs in peacetime and going to war when necessary. The entire world order rested on the divergence of the sexes. Any overlapping or confusion between the roles was seen as a threat to the time- honored order of things. It was felt to be against nature, a deviation from the norm. Sex roles were determined according to the "place" appropriate to each. Women's place was, first and foremost, in the home. The outside world, i. e. workshops, factories and business firms, belonged to men. This sex-based division of the world (private and public) gave rise to a strict dichotomy between the attitudes, which conferred on each its special identity. The woman, sequestered at home, "cared, nurtured and conserved". To do this, she had no need to be daring, ambitious, tough or competitive. The man, on the other hand, competing with his fellow men, was caught up every day in the struggle for survival, and hence developed those characteristics which were thought natural in a man. Today, many women go out to work, and their reasons for doing so have changed considerably. Besides the traditional financial incentives, we find ambition and personal fulfillment motivating those in the most favorable circumstances, and the wish to have a social life and to get out of their domestic isolation influencing others. Above all, for all women, work is invariably connected with the desire for independence.

单选题Curt Dunnam bought a Chevrolet Blazer with one of the most popular new features in high-end cars: the OnStar personal security system. The heavily advertised communications and tracking feature is used nationwide by more than two million drivers, who simply push a button to connect, via a built-in cellphone, to a member of the OnStar staff. A Global Positioning System, or G. P. S. , helps the employee give verbal directions to the driver or locate the car after an accident. The company can even send a signal to unlock car doors for locked-out owners, or honk the horn to help people find their cars in an endless plain of parking spaces. The biggest selling point for the system is its use in thwarting car thieves. Once an owner reports to the police that a car has been stolen, the company can track it to help intercept the thieves, a service it performs about 400 times each month. But for Mr. Dunnam, the more he learned about his car's security features, the less secure he felt. He has enough technical knowledge to worry that someone else-law enforcement officers, or hackers-could listen in on his phone calls, or gain control over his automotive systems without his knowledge or consent. "While I don't believe G. M. intentionally designed this system to facilitate such activities, they sure have made it easy," he said. Mr. Dunnam said he had become even more concerned because of a federal appeals court case involving a criminal investigation, in which federal authorities had demanded that a company attach a wiretap to tracking services like those installed in his car. The suit did not reveal which company was involved. A three-judge panel in San Francisco rejected the request, but not on privacy grounds; the panel said the wiretap would interfere with the operation of the safety services. OnStar has said that its equipment was not involved in that case. An OnStar spokeswoman, Geri Lama, suggested that Mr. Dunnam's worries were overblown. The signals that the company sends to unlock car doors or track location-based information can be triggered only with a secure exchange of specific identifying data, which ought to deter all but the most determined hackers, she said.

单选题Systems of divination in Rome and Athens differed no less than religions, and the differences lay in the same direction. Roman divination was confined to "a simple question, always the same, and relating strictly to the present or to the immediate future. The question might be formulated thus: ' Do the gods favor, or not favor the thing that the consultant is about to do, or which is about to be done under his auspices?' The question admits only of the alternatives ' yes' or ' no' and recognizes only positive or negative things...As for the methods of divination prescribed by the augural ritual, they were as simple and few in number as possible. Observation of birds was the basis of it; and it would have remained the only source of auspices had not the prestige of the fulgural art of the Etruscans influenced the Romans to ' observe the sky' and even to attribute a higher significance to the mysterious phenomena of lightning. Official divination knew neither oracles, nor lots, nor the inspection of entrails. If it refused to become involved in the discussion and appraisal of fortuitous signs, taking account of them only as they occurred in the taking of auspices. With all the more reason it refrained from interpreting prodigies. " What the Romans could not find at home, they sought abroad in Greece and Etruria, where a freer imagination was creating new forms of divination. In the importance attached to the plain association of acts and ideas we must seek the explanation of one of the most extraordinary rules of Roman divination, the rule giving a counterfeit augury the same efficacy as a sign that had actually been observed. "He (the augur) could...rest content with the first sign, if it was favorable, or let unfavorable signs pass and wait for better ones. Then again, he could have the assistant augur 'renounce', that is, 'announce', that the expected birds were flying or singing in the manner desired a practice, in fact, more trustworthy and which later became the regular procedure. This announcement, the renunciation, made according to a sacramental formula, created an 'original auspice' equivalent, for the purposes of the individual hearing it, to a real auspice. " The Romans dealt with substance according to their convenience, at the same time paying strict regard to forms, or better, to certain associations of ideas and acts. The Athenians modified both substance and forms, The Spartans were loathed to change either. Before the Battle of Marathon the Athenians appealed to Sparta for assistance. "The Spartan authorities readily promised their aid, but unfortunately it was now the ninth day of the moon; an ancient law or custom forbade them to march, in this month at least, during the last quarter before the full moon; but after the full they engaged to march without delay. Five days' delay at this critical moment might prove the utter ruin of the endangered city; yet the reason assigned seems to have been no pretence on the part of the Spartans. It was mere blind tenacity of ancient habit, which we shall find to abate, thought never to disappear, as we advance in their history. " The Athenians would have changed both substance and form. The Romans changed substance, respecting form. In order to make a declaration of war a member of the college of Heralds (Feciales) had to hurl a spear into the territory of the enemy. But how to perform the rite and declare war on Pyrrhus when that king's states were so far away from Rome? Nothing simpler' The Romans had captured a soldier of Pyrrhus. They had him buy a plot of ground in the Flaminian Circus; the herald hurled his spear upon that property. So the feeling in the Roman people that there was a close connection between a hurled spear and a just war was duly respected. Ancient Roman law presents the same traits that are observable in religion and divination; and that tends to strengthen our impression that it must be a question of an intrinsic characteristic of the Roman mind asserting itself in the various branches of human activity. Furthermore, in Roman law, as in Roman religion and divination, there are qualitative difference that come out in any comparison with Athens. Says Von Jhering, "The written word of the word pronounced under circumstances of solemnity—the formula— strikes primitive peoples as something mysterious, and faith itself ascribes supernatural powers to it. Nowhere has faith in the word been stronger than in ancient Rome. Respect for the word permeates all relationships in public and private life and in religion, custom, and law. For the ancient Roman the word is a power-it bends and it loosens. If it cannot move mountains, it can at least transfer a crop of grain from one man's field to a neighbor's. It can call forth divinities (devocare) and induce then to abandon a besieged city (evocatio deorum)".

Although recent years have seen
substantial reductions in noxious pollutants from individual motor vehicles, the
number of such vehicles has been steadily increasing. Consequently more than 100
cities in the United States still have levels of carbon monoxide, particulate
matter, and ozone (generated by photochemical reactions with hydrocarbons from
vehicle exhaust) that exceed legally established limits. There is a growing
realization that the only effective way to achieve further reductions in vehicle
emissions--short of a massive shift away from the private automobile—is to
replace conventional diesel fuel and gasoline with cleaner-burning fuels such as
compressed natural gas, liquefied petroleum gas, ethanol, or methanol.
All of these alternatives are carbon-based fuels whose molecules are
smaller and simpler than those of gasoline. These molecules burn mom cleanly
than gasoline, in part because they have fewer, if any, carbon-carbon bonds, and
the hydrocarbons they do emit are less likely to generate ozone. The combustion
of larger molecules, which have multiple carbon-carbon bonds, involves a more
complex series of reaction. These reactions increase the probability of
incomplete combustion and are more likely to release un-combusted and
photo-chemically active hydrocarbon compounds into the atmosphere. On the other
hand, alternative fuels do have drawbacks. Compressed natural gas would require
that vehicles have a set of heavy fuel tanks—a serious liability in terms of
performance and fuel efficiency-and liquefied petroleum gas faces fundamental
limits in supply. Ethanol and methanol, on the other hand, have
important advantages over other carbon based alternative fuels: they have a
higher energy content per volume and would require minimal changes in the
existing network for distributing motor fuel. Ethanol is commonly used as a
gasoline supplement, but k is currently about twice as expensive as methanol,
the low cost of which is one of its attractive features. Methanol's most
attractive feature, however, is that it can reduce by about 90 percent the
vehicle emissions that form ozone, the most serious urban air
pollutant. Like any alternative fuel, methan61 has its critics.
Yet much of the criticism is based on the use of "gasoline done" vehicles that
do not incorporate even the simplest design improvements that are made possible
with the use of methanol. It is true, for example, that a given volume of
methanol provides only about one-half of the energy that gasoline and diesel
fuel do; other things being equal, the fuel tank would have to be somewhat
larger and heavier. However, since methanol-fueled vehicles could be designed to
be much more efficient than "gasoline clone" vehicles fueled with methanol, they
would need comparatively less fuel Vehicles incorporating only the simplest of
the engine improvements that methanol makes feasible would still contribute to
an immediate lessening of urban air pollution.

It remains to be seen whether the
reserves of raw materials in the year 2000 will be sufficient to supply a world
economy which will have grown by five hundred percent. Southeast Asia alone will
have an energy consumption five times greater than that of Western Europe in
1970. Incidentally, if the underdeveloped countries started using up petrol at
the same rate as the industrialized areas, then world reserves would be
exhausted by 1990. All this only goes to show just how important
it is to set up a plan to conserve and divide up fairly natural resources on a
worldwide scale. This is a matter of life and death because
world population is expanding at an incredible rate. By the middle of the next
century population will expand every year by as much as it did in the first
1,500 years after Christ. In the southern, poor parts of the globe, the figures
are enough to make your hair stand on end. Even supposing that steps are taken
to stabilize world population in the next fifty years, the number of inhabitants
per square kilometer will increase by from 4 in the United States to 140 in
South East Asia. What can we do about it? In the first
hypothesis we do nothing. By the year 2000, the southern parts of the world
would then have a population greater than the total world population
today. Alternately we could start acting right now to bring
birth rate under control within fifteen years so that population levels off.
Even then the population in the southern areas would not stop growing for
seventy-five years. And the population would level off at something like twice
today's figure. Finally, we could wait ten to twenty years
before taking action. If we wait ten years the population of the southern area
would stabilize at 3,000 million. Even today the number of potential workers
increases by 350,000 people per week. By the end of the century this figure will
reach 750,000; in other words, it will be necessary to find work for 40 million
people per year--not to speak of food. What this means in
practical terms we can scarcely imagine. But clearly if we do nothing, nature
will solve the problem for us. But at what cost!

单选题Pretty in pink: adult women do not remember being so obsessed with the colour, yet it is pervasive in our young girls" lives. It is not that pink is intrinsically bad, but it is such a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repeatedly and firmly fuses girls"identity to appearance. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidence of innocence. Looking around, I despaired at the singular lack of imagination about girls" lives and interests.
Girls" attraction to pink may seem unavoidable, somehow encoded in their DNA, but according to Jo Paoletti, an associate professor of American Studies, it is not. Children were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What"s more, both boys and girls wore what were thought of as gender-neutral dresses. When nursery colours were introduced, pink was actually considered the more masculine colour, a pastel version of red, which was associated with strength. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolized femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children"s marketing strategy, that pink fully came into its own, when it began to seem inherently attractive to girls, part of what defined them as female, at least for the first few critical years.
I had not realized how profoundly marketing trends dictated our perception of what is natural to kids, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts developed after years of research into children"s behaviour: wrong. Turns out, according to Daniel Cook, a historian of childhood consumerism, it was popularized as a marketing trick by clothing manufacturers in the 1930s.
Trade publications counseled department stores that, in order to increase sales, they should create a "third stepping stone" between infant wear and older kids" clothes. It was only after "toddler" became a common shoppers" term that it evolved into a broadly accepted developmental stage. Splitting kids, or adults, into ever-tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differences—or invent them where they did not previously exist.

单选题Ask why most people are right-handed, and the answer might fall along the same lines as why fish school(鱼成群地游). Two neuroscientists suggest that social pressures drive individuals to coordinate their behaviors so that everyone in the group gets an evolutionary edge. Approximately 85 percent of people prefer their right hand, which is controlled by the left hemisphere of the brain. One theorized benefit of locating a particular function in one hemisphere is that it frees the other to deal with different tasks. But that idea does not explain why. population-wide trends for handedness exist in the first place. Moreover, evidence gleaned in recent years has overturned the long-held belief that human handedness is a unique by-product of brain specialization attributable to language. A suite of studies has revealed brain lateralization in species from fish to primates(灵长类). Last August, for instance, scientists discovered that in the wild, chimpanzees show hand preferences. The presence of lateralization throughout the animal kingdom suggests some benefit from it, contend neuroscientists Giorgio Vallortigara of the University of Trieste and Lesley Rogers of the University of New England in Australia. Also, last August, in the journal Behavioral and Brain Sciences, the two presented evidence to support their idea that social constraints force individuals toward asymmetry in the same direction. They noted, for example, that baby chickens attack more readily when a threat appears on their left. And Rogers has found that chicks with more asymmetrical brains form more stable social groups: perhaps by approaching each other on the right, she hypothesizes, the chicks fight one another less and are more likely to notice predators. Lateralization seems to confer an advantage for some fish as well. In certain species, the majority tend to swim left when a predator attacks, whereas other species head right. The potential benefits of such patterns may not seem intuitive: a predator could learn that attacking a fish on one particular side is more effective. But Vallortigara and Rogers's idea fits with the conventional explanation of why fish school at all. When threatened, fish turning in the same direction have a greater chance of survival than if they scatter to become a darting swarm of head-butting fish. Nevertheless, the bird and fish. data do not explain human handedness. "The issue then becomes: maybe this lateralization long predates the rise of the mammals," speculates Robin Dunbar ,an evolutionary psychologist at the University of Liverpool in England.

单选题The domestic economy in the United States expanded in a remarkably vigorous and steady fashion. The revival in consumer confidence was reflected in the higher proportion of incomes spent for goods and services and the marked increase in consumer willingness to take on installment debt. A parallel strengthening in business psychology was manifested in a stepped-up rate of plant and equipment spending and a gradual pickup in expenses for inventory. Confidence in the economy was also reflected in the strength of the stock market and in the stability of the bond market. For the year as a whole, consumer and business sentiment benefited from the ease in East-West tensions. The bases of the business expansion were to be found mainly in the stimulative monetary and fiscal policies that had been pursued. Moreover, the restoration of sounder liquidity positions and tighter management control of production efficiency had also helped lay the groundwork for a strong expansion. In addition, the economic policy moves made by the President had served to renew optimism on the business outlook while boosting hopes that inflation would be brought under more effective control. Finally, of course, the economy was able to grow as vigorously as it did because sufficient leeway existed in terms of idle men and machines. The United States balance of payments deficit declined sharply. Nevertheless, by any other test, the deficit remained very large, and there was actually a substantial deterioration in our trade account to a sizable deficit, almost two-thirds of which was with Japan. While the overall trade performance proved disappointing, there are still good reasons for expecting the delayed impact of devaluation to produce in time a significant strengthening in our trade picture. Given the size of the Japanese component of our trade deficit, however, the outcome will depend importantly on the extent of the corrective measures undertaken by Japan. Also important will be our own efforts in the United States to fashion internal policies consistent with an improvement in our external balance. The underlying task of public policy for the year ahead--and indeed for the longer run--remained a familiar one: to strike the right balance between encouraging healthy economic growth and avoiding inflationary pressures. With the economy showing sustained and vigorous growth, and with the currency crisis highlighting the need to improve our Competitive posture internationally, the emphasis seemed to be shifting to the problem of inflation. The Phase Three program of wage and price restraint can contribute to reducing inflation. Unless productivity growth is unexpectedly large, however, the expansion of real output must eventually begin to slow down to the economy's larger run growth potential if generalized demand pressures on prices are to be avoided.

单选题It was 3:45 in the morning when the vote was finally taken. After six months of arguing and final 16 hours of hot parliamentary debates, Australia"s Northern Territory became the first legal authority in the world to allow doctors to take the lives of incurably ill patients who wish to die. The measure passed by the convincing vote of 15 to 10. Almost immediately word flashed on the Internet and was picked up, half a world away, by John Hofsess, executive director of the Right to Die Society of Canada. He sent it on via the group"s on line service, Death NET. Says Hofsess: "We posted bulletins all day long, because of course this isn"t just something that happened in Australia. It"s world history."
The full import may take a while to sink in. The NT Rights of the Terminally Ⅲ law has left physicians and citizens alike trying to deal with its moral and practical implications. Some have breathed sighs of relief, others, including churches, right to life groups and the Australian Medical Association, bitterly attacked the bill and the haste of its passage. But the tide is unlikely to turn back. In Australia—where an aging population, life extending technology and changing community attitudes have all played their part—other states are going to consider making a similar law to deal with euthanasia In the U.S. and Canada, where the right to die movement is gathering strength, observers are waiting for the dominoes to start falling.
Under the new Northern Territory law, an adult patient can request death—probably by a deadly injection or pill—to put an end to suffering. The patient must be diagnosed as terminally ill by two doctors. After a "cooling off" period of seven days, the patient can sign a certificate of request. After 48 hours the wish for death can be met. For Lloyd Nickson, a 54 year old Darwin resident suffering from lung cancer, the NT Rights of Terminally Ⅲ law means he can get on with living without the haunting fear of his suffering: a terrifying death from his breathing condition. "I"m not afraid of dying from a spiritual point of view, but what I was afraid of was how I"d go, because I"ve watched people die in the hospital fighting for oxygen and clawing at their masks," he says.

Called by many critics the greatest
achievement of English lyrical poetry, this elegy was written upon the death of
a fellow alumnus of Milton's, Edward King, who was drowned in the Irish Sea in
1637. A group of King's former schoolmates at Cambridge issued a commemorative
volume titled Obsequies to the Memory of Mr. Edward King (1638). It was in this
limited publication that Lycidas first appeared. Heretofore, of his great poems
only Comus had been published, and that anonymously. Lycidas is
not an expression of personal grief ( personal grief was to be eloquent in
Milton's next important poem, the Latin Epitaphium Damonis), but rather a record
of the thoughts that King's death evoked in the poet. King had written verses
himself and had prepared himself for the Church. These two facts of the dead
man's career form the basis for what Milton had to say. Outwardly the poem is
written in the tradition of pastoral poetry, and more particularly in the
tradition of the pastoral elegy as exhibited in the ancient Greek Lament for
Bion by Moschus. The poet is spoken of as a shepherd. But Milton introduces the
innovation of identifying the Christian idea of shepherd (pastor) as meaning
priest. In a wonderful fusion of pagan and Christian tradition, Milton makes his
elegy the occasion for a scathing attack on the corruptions of the clergy in his
time, with parenthetical thrusts of scorn at his trivial contemporaries, the
Cavalier poets. Samuel Johnson, who disliked all pastoral
poetry, made the one outstandingly foolish judgment of his career, in dismissing
Lycidas as a work of an. He said its "diction is harsh, the rhymes uncertain,
and the numbers unpleasing, "--a testimony of the fact that Johnson was deaf to
the refinements of English poetry at its subtlest, for Lycidas is an exquisite
piece of music from the first line through the last. Moreover, Johnson was upset
at the mingling of "trifling fictions" with "the most awful and sacred truths,
such as ought never to be polluted with such irreverent combinations." That
pronouncement can only mean that Johnson failed to grasp the noble idea at the
center of the poem: Milton's definition of the high function of a
poet.
单选题Dollars and cents are the basic units of American money. The back of all dollar bills are green (hence "greenbacks"). The commonly used coins are: one cent (penny), five cents (nickel), 10 cents (dime), and 25 cents (quarter). 50 pieces (half dollar) and silver dollars (not really silver anymore) are gaining in usage, while there has been talk of phasing out the penny that's inflation for you. "Always carry plenty of quarters when travelling. Very useful for phones, soda machines, laundry machines, etc." There is generally no problem in using US dollars in Canada, but this is never possible in reverse. It's useful always to carry small change for things like exact fare buses, but do not carry large sums of cash. Instead keep the bulk of your money in travellers' cheques which can be purchased both in the US and abroad and should be in dollar denominations. The best known cheques are those of American Express, so you will have the least difficulty cashing these, even in out of the way places. Thomas Cook travellers' cheques are also acceptable, especially as lost ones can be reclaimed at some car rental companies. Dollar denomination cheques can be used like regular money. There's no need to cash them at a bank: use them instead to pay for meals, supermarket purchases or whatever. Ten or twenty dollar cheques are accepted like this almost always and you'll be given change just as though you'd presented the cashier with dollar bills. Be prepared to show ID when you cash your cheques. Credit cards can be even more valuable than travellers' cheques, as they are often used to guaraniee room reservations over the phone and are accepted in lieu of deposit when renting a car—indeed without a credit card you may be considered so untrustworthy that not only a deposit but your passport will be held as security too. The major credit cards are VISA, Master Charge and Access, Diners Club and American Express. If you hold a bank card, it could well be worthwhile to increase your credit limit for travel purposes—you should ask your bank manager.

A poor traveler stopped under the tree
to eat the boiled rice and vegetables which he brought with him. A few meters
away, there was a small shop by the side of the road where a woman was frying
fish and selling it to travelers. The woman watched the poor traveler carefully,
and when he finished his food and began to go, she shouted rudely, "You have not
paid me for the fried fish? "But I have not had any fried
fish!" he said. "But everyone can see that you enjoyed the smell
of my fried fish with your rice and veg- etables," said the woman, "If you had
not smelled the fish, your meal would not have been so pleasant !"
Soon a crowd collected, and although they supported the poor traveler,
they had to ad- mit that wind was blowing from the shop to the place where he
had eaten, and that it had carried the smell of the fried fish to him.
Finally, the woman took the poor traveler to a judge, who said, "The woman
says that the traveler ate his meal with the smell of her fried fish. The
traveler agrees that the wind was blowing the smell of her fried fish to his
nose while he was eating, so he must pay for it." "What does your fried fish
cost?" he asked the woman. "Twenty-five cents a plate," she
answered delighted. "Then go outside together," said the judge.
"There the traveler must hold up a twenty five-cent piece so that a shadow(影子)
falls on the woman's hand. The price of the smell of a plate of fried fish is
the shadow of twenty-five cents."

单选题The Last Supper is a late 15th-century mural painting by Leonardo da Vinci in the refectory of the Convent of Santa Maria delle Grazie, Milan. The work is presumed to have been commenced around 1495 and was commissioned as part of a scheme of renovations to the church and its convent buildings by Leonardo"s patron Ludovico Sforza, Duke of Milan. The painting represents the scene of The Last Supper of Jesus with his disciples, as it is told in the Gospel of John. Leonardo has depicted the consternation that occurred among the Twelve Disciples when Jesus announced that one of them would betray him. The Last Supper measures 460cm×880cm and covers an end wall of the dining hall at the monastery of Santa Maria delle Grazie in Milan, Italy. The theme was a traditional one for refectories, although the room was not a refectory at the time that Leonardo painted it. The main church building had only recently been completed(in 1498), but was remodeled by Bra-mante, hired by Ludovico Sforza to build a Sforza family mausoleum. The painting was commissioned by Sforza to be the centerpiece of the mausoleum. The lunettes above the main painting, formed by the triple arched ceiling of the refectory, are painted with Sforza coats-of-arms. The opposite wall of the refectory is covered by the Crucifixion fresco by Giovanni Donatoda Montorfano, to which Leonardo added figures of the Sforza family in tempera. Leonardo began work on The Last Supper in 1495 and completed it in 1498—he did not work on the painting continuously. The beginning date is not certain; as the archives of the convent for the period have been destroyed and a document dated 1497 indicates that the painting was nearly completed at that date. One story goes that a prior from the monastery complained to Leonardo about the delay, enraging him. He wrote to the head of the monastery, explaining he had been struggling to find the perfect villainous face for Judas, and that if he could not find a face corresponding with what he had in mind, he would use the features of the prior who complained. In common with other depictions of The Last Supper from this period, Leonardo seats the diners on one side of the table, so that none of them have their backs to the viewer. Most previous depictions excluded Judas by placing him alone on the opposite side of the table from the other eleven disciples and Jesus or placing halos around all the disciples except Judas. Leonardo instead has Judas lean back into shadow. Jesus is predicting that his betrayer will take the bread at the same time he does to Saints Thomas and James to his left, who react in horror as Jesus points with his left hand to a piece of bread before them. Distracted by the conversation between John and Peter, Judas reaches for a different piece of bread not noticing Jesus too stretching out with his right hand towards it. The angles and lighting draw attention to Jesus, whose head is located at the vanishing point for all perspective lines. The painting contains several references to the number 3, which represents the Christian belief in the Holy Trinity. The Apostles are seated in groupings of three; there are three windows behind Jesus; and the shape of Jesus" figure resembles a triangle. There may have been other references that have since been lost as the painting deteriorated.

单选题Anyone who has ever attended a university knows that the quality of lecturers varies greatly. A few are very effective communicators, conveying the substance of their lectures clearly and interestingly and inspiring students to want to know more about the subject. Others produce dull lectures from which the students learn little and which are likely to kill any interest they may have in the subject. Lecturing is a major part of a university lecturer's job and it would seem reasonable that effectiveness in this task should be a major standard in assessing a lecturer for promotion. However, it is very often the case that far more weight is given to such factors as participation in research, number of publications and even performance of administrative duties. My point of view is that a lecturer's lecturing should be regularly evaluated and that the best people to carry out this evaluation are those directly on the receiving end. It could, of course, be argued that students are not competent to evaluate the academic quality of lectures, If anyone should evaluate lecturers, it should be their colleagues. However, I am not arguing that students should be asked to comment on the academic content of lectures, but to evaluate the effectiveness. I suspect that many of the objections to student evaluation stem from the fear some lecturers have of being subject to criticism by their students. However, lecturers should see such evaluation as an opportunity to become aware of defects in their lecturing techniques and thus to become better lecturers. Such a system should benefit both students and lecturers as well as help department heads to assess the strengths and weaknesses of their teaching staff.

The way a meal is cooked and served is most important and an (22) served meal will improve a child's appetite. Never ask a child (23) he likes or dislikes a food and never discuss likes and dislikes in front of him or allow (24) else to do so. If the father says he hates fat meat or the mother refuses vegetables in the child's hearing he is (25) to copy this procedure. Take it (26) granted that he likes everything and he probably will. Nothing healthful should be omitted for the meal because of a supposed dislike. At meal times it is a good idea to give a child a small portion and let him come back for a second helping rather than give him as (27) as he is likely to eat all at once. Do not talk too much to the child (28) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food so he can hurry back to his toys. Under (29) circumstances must a child be coaxed(哄骗) (30) forced to eat.
单选题Years ago our cities were full of cars, buses and trucks. Now the streets are completely congested (拥挤的) and it is very difficult to drive a car along them. Drivers must stop at hundreds of traffic lights. What are our cities going to be like in ten or twenty years? Will enormous (巨大) motorways be built across them? With big motorways cutting across them, full of noisy, dirty cars and lorries, our cities are going to be awful places. How can we solve the problem? There are some good ideas to reduce the use of private cars. In 1989, for example, the authorities in Rome began an interesting experiment: passengers on the city buses did not have to pay for their tickets. In Stockholm there was another experiment: people paid very little for a season ticket to travel on any bus, trolley bus, train or tram in all the city. In many cities now some streets are closed to vehicles, and pedestrians are safe there. In London there is another experiment: part of the street is for buses only, so the buses can travel fast. There are no cars or taxies in front of them.
单选题There are many factors which may have an influence on adults and children being able to lead a healthy life. Nowadays, people are very busy. Often, both parents work outside the home. Children are expected to take on more responsibility at home to help their parents. They also have sporting and leisure activities as well as school expectations. The busyness also adds another factor: the need to use cars to get from one place to another quickly. Today, society places a lot of emphasis on technology. Computers, DVDs, CDs, television, Playstations and Xboxes have become major leisure activities, rather than traditional more active pursuits. This has led to a more sedentary lifestyle. The media provide entertainment and information. Unfortunately, they also promote fast food which fits easily into busy lifestyles. It is much more convenient at times to buy a quick takeaway rather than prepare a meal. The media constantly bombard (轰炸) their audience with "perfect" body images, the need to buy the most fashionable clothes, the most up-to-date computer games, the best places to visit and the best things to do. Environments vary. We may be exposed to pollution, such as cigarette smoke. This can be harmful to people who suffer from breathing difficulties. Environments where passive smoking is unavoidable make it difficult to lead a healthy life. Perhaps the important factor influencing healthy lifestyles is motivation, or the desire to be healthy. Any person who wants to be healthy will find a way to be healthy—if he/she is motivated enough!

great change always bring out the risk-takers," he said, "and they leave winners

fleeing from the field. I didn't turn away from mine entirely, but instead
linked it to the Internet. My plan was to offer consumers descriptions of
home-design products by using a special software and let them modify the
designs. Then we can enable them to get online professional and constructional
help to have their houses built, decorated and furnished according to their own
choice. To realize my plan I needed investors, so I continued to meet regularly
with venture capitalists. One said I had a great idea. But I needed to test
it. I was working nonstop-struggling to find the fight way
ahead. The pressure was terrible. To get the money from a venture capitalist is
going to cost my wife and my children ! It was just at this time that my parents
and sisters stepped up. Two hundred thousand dollars is a lot of money to them,
but they invested in this crazy son and brother without a moment's hesitation.
With their help my company survived and has been prospering ever since.

单选题"Making money is a dirty game," says the Institute of Economic Affairs. summing up the attitude of British novelists towards business. The IEA. a free market think-tank, has just published a collection of essays (The Representation of Business in English Literature) by five academics chronicling the hostility of the country's men and women of letters to the sordid business of making money. The implication is that Britain's economic performance Is retarded by an anti-industrial culture. Rather than blaming rebellious workers and incompetent managers for Britain's economic worries. then, we can put George Orwell and Martin Amis in the dock instead. From Dickens's Scrooge to Amis's John Self in his 1980s novel Money, novelists have conjured up a rogue's gallery of mean. greedy, amoral money-men that has alienated their impressionable readers from the noble pursuit of capitalism. The argument has been well made before, most famously in 1981 by Martin Wiener. an American academic, in his English Culture and the Decline of the Industrial Spirit. Lady Thatcher was an admirer of Mr. Wiener's. and she led a crusade to revive the "entrepreneurial culture" which the liberal elite had allegedly trampled underfoot. The present Chancellor of the Exchequer, Gordon Brown, sounds as though he agrees with her. At a recent speech to the Confederation of British Industry, he declared that it should be the duty of every teacher in the country to "communicate the virtues of business and enterprise". Certainly, most novelists are hostile to capitalism, but this refrain risks scapegoating writers for failings for which they are not to blame. Britain's culture is no more anti-business than that of other countries. The Romantic Movement. which started as a reaction against the industrial revolution of the 21st century, was born and flourished in Germany, but has not stopped the Germans from being Europe's most successful entreprcneurs and industrialists. Even the Americans are guilty of blackening business's name. SMERSH and SPECTRE went our with the cold war, James Bond now takes on international media magnates rather than Rosa Kleb. His films such as Erin Brockovich have pitched downtrodden, moral heroes against the evil of faceless corporatism. Yet none of this seems to have dented America's lust for free enterprise. The irony is that the novel flourished as an art form only after, and as a result of. the creation of the new commercial classes of Victorian England, just as the modem Hollywood film can exist only in an era of mass consumerism. Perhaps the moral is that capitalist societies consume literature and film to let off steam rather than to change the world.
单选题Even today, when air and road travel has made Africa so readily accessible to Europeans and Americans, there are innumerable aspects of African life which tend to take one by surprise. The unfamiliar lies hidden every where, and the presence of Western culture seems merely to emphasize this unfamiliarity. Basically, the essence of our reaction to the strange, the unfamiliar, is a sense of fear. Every country contains landscapes that arouse unease-whether it be some remote Alpine valley, the wild lavender fields of Upper Province, or a lonely Norwegian fjord at twilight But in my own experience West Africa contains more weird and eerie regions-rain-forest, mangrove swamp, parched plains of red earth-than any other place that I have seen. It is not only in the foreigner that these landscapes evoke fear. A large part of all old African religions is devoted to soothing the unknown and the unseen-evil Spirits which live in a particular tree or a particular rock, a thousand varieties of ghosts and witches, the ever-present spirits of dead ancestors or relatives. I have myself been kept awake at night in Calabar by a friend from Lagos who was convinced that the witches of the east were out to get him, or that he was about to be kidnapped and eaten. During four and a half hours in a canoe along the creeks of the Niger delta, gliding over the still and colorless water beneath an equally still and colorless but burning sky, I, too, have experienced a sense of fear, or at least a sense of awe. Except for the ticking of the little outboard engine the silence was complete. On either hand stretched the silver-white swamps of mangrove, seeming, with their awkward exposed roots, to be standing knee-deep in the water. Where the creek narrowed you could peer deep into these thickets of mangroves-vistas secret, interminable and somehow meaningless. There was no sign of life except for the shrill screech of some unseen bird. I was on my way to the ancient slaving port of Bonny .which we reached in late afternoon. Scrambling up some derelict stone steps (slithery with slime and which had managed to detach themselves from the landing-stage so that you had to jump a two-foot gap to reach wet land), I found myself in an area of black mud and tumbled blocks of stone.

The whole industrial process which
makes many of the goods and machines we need and use in our daily lives, is
bound to create a number of waste products which upset the environmental balance
or the ecological(生态的)balance as it is known. Many of these waste products can
be prevented or disposed(处理) of sensibly, but clearly while more and more new
goods are produced and made complex, there will be new, dangerous wastes to be
disposed of, for example, the waste products from nuclear power stations. Many
people therefore see pollution as only part of a larger and more complex
problem, that is, the whole process of industrial production and consumption of
goods. Others see the problem mainly in connection with agriculture, where new
methods are helping farmers grow more and more on their land to feed our
ever-increasing population. However, the land itself is gradually becoming worn
out as it is being used, in some cases, too heavily, and artificial
fertilizers(人造肥料) cannot bring back the balance. Whatever is
underlying(潜在的)reasons, there is no doubt that much of the pollution caused
could be controlled if only companies, individuals and governments would make
more efforts. In the home there is an obvious need to control litter(杂乱的废物)and
waste. Food is wrapped up three or four times in packages that all have to be
disposed of; drinks are increasingly sold in bottles or tins which cannot be
reused. This not only causes a litter problem, but also is a great waste of
resources, in terms of glass, metals and paper. Advertising has helped this
process by persuading many of us to buy things we don't want to buy. Pollution
and waste continue to be a problem everyone can help to solve by cutting out
unnecessary buying, excess consumption and careless disposal of the products we
use in our daily lives.

单选题Unlike the carefully weighed and planned compositions of Dante, Goethe"s writings always have a sense of immediacy and enthusiasm. He was a constant experimenter with life, with ideas and with forms of writing. For the same reason, his works seldom have the qualities of finish or formal beauty which distinguish the masterpieces of Dante and Virgil. He came to love the beauties of classicism, but it was never an essential part of his make-up. Instead, the urgency of the moment, the spirit of the thing, guided his pen. As a result, nearly all his works have serious flaw of structure, of inconsistencies, of excesses and redundancies and extremities.
In a large sense, Goethe represents the fullest development of the romanticism. It has been argued that he should not be so designated because he so clearly matured and outgrew the kind of romanticism exhibited by Wordsworth, Shelley, and Keats. Shelley and Keats died young; Wordsworth lived narrowly and abandoned his early attitudes. In contrast, Goethe lived abundantly and developed his faith in the spirit, his understanding of nature and human nature, and his reliance on feelings as man"s essential motivating force. The result was an all-encompassing vision of reality and a philosophy of life broader and deeper than the partial visions and attitudes of other romanticists. Yet the spirit of youthfulness, the impatience with close reasoning or "logic chopping", and the continued faith in nature remained his to the end, together with an occasional waywardness and impulsiveness and a disregard of artistic or logical propriety, which savor strongly of romantic individualism. Since so many twentieth century thoughts and attitudes are similarly based on the stimulus of the Romantic Movement. Goethe stands as particularly the poet of the modern man as Dante stood for medieval man and as Shakespeare for the man of the Renaissance.

Andrea had never seen an old lady hitchhiking
before. However, the weather and the coming darkness made her feel sorry for the
lady. The old lady had some difficulty in climbing through the car door, and
pushed her big brown canvas shopping bag down onto the floor under her feet. She
said to Andrea, in a voice that was almost a whisper, "Thank you dear - I'm just
going to Brock Bourne" Something in the way the lady spoke, and
the way she never turned her head, made Andrea uneasy about this strange
hitchhiker. She didn't know why, but she felt instinctively that there was
something wrong, something old, and something dangerous. But how could an old
lady be dangerous? It was absurd. Careful not to turn her head,
Andrea look sideways at her passenger. She studied the hat, the dirty collar of
the dress, the shapeless body, and the arms with their thick black
hairs. Thick black hairs? Hairy arms? Andrea's
blood froze. This wasn't a woman. It was a man.
At first, she didn't know what to do. Then suddenly, an idea came into her
racing, terrified brain. Swinging the wheel suddenly, she threw the car into a
skid, and brought it to a halt. "My god!" she shouted. "A child!
Did you see the child? I think I hit her. " The "old lady" was
clearly shaken by the sudden skid. "I didn't see anything dear," she said. "I
don't think you hit anything. " "I am sure it was a child!"
insisted Andrea. "Could you just get out and have a look? Just see if there is
anything on the road?" she held her breath. Would her plan work?
It did. The passenger slowly climbed out to investigate. As soon as in
front of her vehicle, Andrea gunned the engine and accelerated madly away, and
soon she had put a good three miles between herself and the awful
hitchhiker. It was only then that she thought about the bag
lying on the floor in front of her. Maybe the bag would provide some information
about the real identity about the man. Pulling into the side of the road, Andrea
opened the heavy bag curiously. It contained only one item — a
small hand axe, with a razor-sharp blade. The axe, and the inside of the bag,
were covered with the dark red stains of dried blood. Andrea
began to scream.

单选题The biggest danger facing the global airline industry is not the effects of terrorism, war, SARS and economic downturn. It is that these blows, which have helped ground three national flag carriers and force two American airlines into bankruptcy, will divert attention from the inherent weaknesses of aviation, which they have exacerbated. As in the crisis that attended the first Gulf War, many airlines hope that traffic will soon bounce back, and a few catastrophic years will be followed by fuller planes, happier passengers and a return to profitability. Yet the industry's problems are deeper--and older--than the trauma of the past two years implies. As the centenary of the first powered flight approaches in December, the industry it launched is still remarkably primitive. The car industry, created not long after the Wright Brothers made history, is now a global industry dominated by a dozen firms, at least half of which make good profits. Yet commercial aviation consists of 267 international carriers and another 500-plus domestic ones. The world's biggest carrier, American Airlines, has barely 7% of the global market, whereas the world's biggest carmaker, General Motors, has (with its associated firms) about a quarter of the world's automobile market. Aviation has been incompletely deregulated, and in only two markets: America and Europe. Everywhere else, governments dictate who flies under what rules. These aim to preserve state-owned national flag-carriers, run for prestige rather than profit. And numerous restrictions on foreign ownership impede cross-border airline mergers. In America, the big network carriers face barriers to exit, which have kept their route networks too large. Trade unions resisting job cuts and Congressmen opposing route closures in their territory conspire to block change. In Europe, liberalization is limited by bilateral deals that prevent, for instance, British Airways (BA) flying to America from Frankfurt or Paris, or Lufthansa offering transatlantic flights from London's Heathrow. To use the car industry analogy, it is as if only Renaults were allowed to drive on French motorways. In airlines, the optimists are those who think that things are now so had that the industry has no option but to evolve. Frederick Reid, president of Delta Air Lines, said earlier this year that events since the September 11th attacks are the equivalent of a meteor strike, changing the climate, creating a sort of nuclear winter and leading to a "compressed evolutionary cycle". So how, looking on the bright side, might the industry look after five years of accelerated development?

单选题In a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.
In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondentschose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.
Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools.
Some Japanese parents believe that if their young children attend a university-based program, it will increase the children"s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.

Nanotechnology, according to its fans,
will jump-start a new industrial revolution with molecular-sized structures as
complex as the human cell and 100 times stronger than steel. The new technology
transforms everyday products and the way they are made by manipulating atoms so
that materials can be shrunk, strengthened and lightened all at once. To date
only modest nanotech-based products—such as stain-resistant fabrics and fresh
food packaging—have entered the market, but some scientists predict
nanotechnology will eventually be the only game in town. "It will be a
ubiquitous technology," said George Stephanopoulos, professor of chemical
engineering at the Massachusetts Institute of Technology. He echoes other
nanotech supporters who say industrial countries are already sliding toward its
use in every aspect of manufacturing. Aided by recent advances
in microscopes, scientists can now place single atoms where they want for the
first time. The potential applications are numerous, with microscopic computers,
cancer-killing antennae and nonpolluting car engines on the distant horizon.
When it's all going to happen, though, is another matter. According to most
scientific accounts, the nanotech future may be 10 to 20 years off. Major
hurdles need to be jumped. First, there is a lack of economic mass production.
Some of the more complicated devices would require exact placement of billions
of atoms. "It may take the lifetime of the universe to complete the construction
of (such a) device," said George Barbastathis, assistant professor at MIT.
Another challenge is bridging the nanoscale and macroscopic, he said. In other
words, the smallness of a nano device is useless when it must be attached to
large wires. It's unclear how scientists will overcome these problems. And fears
derived from science fiction threaten to derail nanotechnology even as it
emerges, in much the same way popular anxiety over "super-weeds" and
"frankenfoods" have hobbled biotechnology in agriculture and fear of "designer
babies" has set back stem-cell research. Lured by a market with
billions of dollars in potential profits, giants like GE, Intel, Motorola and
IBM are already heavily involved in research. Worldwide, the two industries with
the potential to win big with nanotechnology are electronics and biotechnology,
according to MIT researchers. On the biotech front, scientists are promoting the
notion of nanoparticles made from gold that could be triggered remotely to heat
and kill individual cancer cells. Nanotechnology holds equal promise for wealth
creation, hut there isn't a consensus among venture capitalists on how to
realize it. "Which direction is it going to work out in? That's the question on
everyone's mind," Gang Chen, an associate professor at the MIT, told scientists
at a Boston nano gathering.

单选题Once the 12 Girls Band became popular, similar groups predictably starting popping up. Musicat and Beautiful Youth 18 were formed last year. Both feature now-familiar formulas of attractive young women playing different instruments in songs that combine modem music with classic Chinese tunes. Yet they add to the mix by throwing in song, dance and even acrobatics. In an interview, noted music critic Jin Zhaojun said the girl band phenomenon was not new to China, as similar acts appeared in the 1980s. However, the undying role is that to be successful, bands have to have a novel look. "The 12 Girls Band was the first group to give big live shows and show creativity in how they present their performances. The Beijing Red Poppy Ladies Percussion group, formed in 1999, has made a name for itself because they are the only band that exclusively plays drams and percussion instruments. Bands that don't have 'a thing' are sure to die fast," Jin said.

单选题Car makers have long used sex to sell their products. Recently, how. ever, both BMW and Renault have based their latest European marketing campaigns around the icon of modern biology. BMW's campaign, which launches its new 3-series sports saloon in Britain and Ireland, shows the new creation and four of its earlier versions zigzagging around a landscape made up of giant DNA sequences, with a brief explanation that DNA is the molecule responsible for the inheritance of such features as strength, power and intelligence. The Renault offering, which promotes its existing Laguna model, employs evolutionary theory even more explicitly. The company's television commercials intersperse clips of the car with scenes from a lecture by Steve Jones, a professor of genetics at University of London. BMW's campaign is intended to convey the idea of development allied to heritage. The latest product, in other words, should be viewed as the new and improved scion of a long line of good cars. Renault's message is more subtle. It is that evolution works by gradual improvements rather than sudden leaps (in this, Renault is aligning itself with biological orthodoxy). So, although the new car in the advertisement may look like the old one, the external form conceals a number of significant changes to the engine. While these alterations are almost invisible to the average driver, Renault hopes they will improve the car's performance, and ultimately its survival in the marketplace. Whether they actually do so will depend, in part, on whether marketers have .read the public mood correctly. For, even if genetics really does offer a useful metaphor for automobiles, employing it in advertising is not without its dangers. That is because DNA's public image is ambiguous. In one context, people may see it as the cornerstone of modern medical progress. In another, it will bring to mind such controversial issues as abortion, genetically modified foodstuffs, and the sinister subject of eugenics. Car makers are probably standing on safer ground than biologists. But even they can make mistakes. Though it would not be obvious to the casual observer, some of the DNA which features in BMW's ads for its nice, new car once belonged to a woolly mammoth—a beast that has been extinct for 10,000 years. Not, presumably, quite the message that the marketing department was trying to convey.

单选题Sport is heading for an indissoluble marriage with television and the passive spectator will enjoy a private paradise. All of this will be in the future of sport. The spectator(the television audience)will be the priority and professional clubs will have to readjust their structures to adapt to the new reality: sport as a business. The new technologies will mean that spectators will no longer have to wait for broadcasts by the conventional channels. They will be the ones who decide what to see. And they will have to pay for it. In the United States the system of the future has already started: pay-as-you-view. Everything will be offered by television and the spectator will only have to choose. The review "Sports Illustrated " recently published a full profile of the life of the supporter at home in the middle of the next century. It explained that the consumers would be able to select their view of the match on a gigantic, flat screen occupying the whole of one wall, with images of a clarity which cannot be foreseen at present, they could watch from the trainer's stands just behind the batter in a game of baseball or from the helmet of the star player in an American football game. And at their disposal will be the sane options the producer of the recorded programmer has to select replays, to choose which camera to me and to decide on the sound whether to hear the public, the players, the trainer and so on. Many sports executives, largely too old and too conservative to feel at home with the new technologies will believe that sport must control the expansion of television coverage in order to survive and ensure that spectators attend matches. They do not even accept the evidence which contradicts their view while there is more basketball than ever on television, for example, it is also certain that basketball is more popular than ever. It is also the argument of these sports executives that television harming the modest team. This is true, but the future of those teams is also modest. They have reached their ceiling. It is the law of the market. The great events continually attract larger audience. The world is being constructed on new technologies so that people can make the utmost use of their time and, in their home have access to the greatest possible range of recreational activities. Sport will have to adapt itself to the new world. The most visionary executives go further. That philosophy is: rather than see television take over sport why not have sports taken over television?

Erroneous virtues are running out of
control in our culture. I don't know how many times my 13-year-old son has told
me about classmates who received ＄10 for each "A" grade on their report
cards—hinting that I should do the same for him should he ever receive an A.
Whenever he approaches me on this subject, I give him the same reply: forget it!
This is not to say that I would never praise my son for doing well in school.
But my praise is not meant to reward or elicit future achievements, but rather
to express my genuine delight in the satisfaction he feels at having done his
best. Doling out ＄10 sends out the message that the feeling alone isn't good
enough. As a society, we seem to be on the brink of losing our
internal control—the ethical boundaries that guide our actions and feelings.
Instead, these ethical standards have been eclipsed by external "stuff" as a
measure of our worth. We pass this obscene message on to our children. We offer
them money for learning how to convert fractions to decimals. Refreshments are
given as a reward for reading. In fact, in one national reading program, a party
awaits the entire class if each child reads a certain number of books within a
four-month period. We call these things incentives, telling ourselves that if we
can just reel them in and get them hooked, then the internal rewards will
follow. I recently saw a television program where unmarried,
teenage mothers were featured as the participants in a program that offers a ＄10
a week "incentive" if these young women don't get pregnant again. Isn't the
daily plight of being a single, teenaged mother enough to discourage them from
becoming pregnant again? No, it isn't, because we as a society won't allow it to
be. Nothing is permitted to succeed or fail on its own merits anymore.
A staple diet of candy bars makes an ordinary apple or orange seem sour.
Similarly, an endless parade of incentives corrodes our ability to feel a
genuine sense of inner peace (or inner conflict). The simple virtues of honesty,
kindness and integrity suffer from an image problem and are in desperate need of
better publicity. One way to do this is by example. I fear that in our so-called
upwardly mobile world we are on a downward spiral towards becoming morally
bankrupt. We may soon render ourselves worthless inside, while desperately
clinging to a shell of appearances.

单选题Text 2 Not too many decades ago it seemed "obvious" both to the general public and to sociologists that modern society has changed people's natural relations, loosened their responsibilities to kin and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the "obvious" is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else. Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than are big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different stifle of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers. These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young trouble makers. Moreover; as Wirth suggested, there may be a link between a community's population size and its social heterogeneity. For instance, sociologists have found much evidence that the size of a community is associated with bad behavior including gambling, drugs, etc. Large-city urbanites are also more likely than their small-town counterparts to have a cosmopolitan outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so—called undesirables. Everything considered, heterogeneity and unusual behavior seem to be outcomes of large population size.

单选题Text 2 A few common misconceptions. Beauty is only skin-deep. One's physical assets and liabilities don't count all that much in a managerial career. A woman should always try to look her best. Over the last 30 years, social scientists have conducted more than 1,000 studies of how we react to beautiful and not-so-beautiful people. The virtually unanimous conclusion: Looks do matter, more than most of us realize. The data suggest, for example, that physically attractive individuals are more likely to be treated well by their parents, sought out as friends, and pursued romantically. With the possible exception of women seeking managerial jobs, they are also more likely to be hired, paid well, and promoted. Un-American, you say, unfair and extremely unbelievable? Once again, the scientists have caught us mouthing pieties while acting just the contrary. Their typical experiment works something like this. They give each member of a group—college students, perhaps, or teachers or corporate personnel mangers—a piece of paper relating an individual's accomplishments. Attached to the paper is a photograph. While the papers all say exactly the same thing the pictures are different. Some show a strikingly attractive person, some an average-looking character, and some an unusually unattractive human being. Group members are asked to rate the individual on certain attributes, anything from personal warmth to the likelihood that he or she will be promoted. Almost invariably, the better looking the person in the picture, the higher the person is rated. In the phrase, borrowed from Sappho, that the social scientists use to sum up the common perception, what is beautiful is good. In business, however, good looks cut both ways for women, and deeper than for men. A Utah State University professor, who is an authority on the subject, explains: In terms of their careers, the impact of physical attractiveness on males in only modest. But its potential impact on females can be tremendous, making it easier, for example, for the more attractive to get jobs where they are in the public eye. On another note, though, there is enough literature now for us to conclude that attractive women who aspire to managerial positions do not get on as well as women who may be less attractive.

单选题Over the past century, all kinds of unfairness and discrimination have been condemned or made illegal. But one insidious form continues to thrive: alphabetism. This, for those as yet unaware of such a disadvantage, refers to discrimination against those whose surnames begin with a letter in the lower half of the alphabet. It has long been known that a taxi firm called AAAA cars has a big advantage over Zodiac cars when customers thumb through their phone directories. Less well known is the advantage that Adam Abbott has in life over Zoё Zysman. English names are fairly evenly spread between the halves of the alphabet. Yet a suspiciously large number of top people have surnames beginning with letters between A and K. Thus the American president and vice-president have surnames starting with B and C respectively; and 26 of George Bush's predecessors (including his father) had surnames in the first half of the alphabet against just 16 in the second half. Even more striking, six of the seven heads of government of the G7 rich countries are alphabetically advantaged (Berlusconi, Blair, Bush, Chirac, Chrétien and Koizumi). The world's three top central bankers (Greenspan, Duisenberg and Hayami) are all close to the top of the alphabet, even if one of them really uses Japanese characters. As are the world's five richest men (Gates, Buffet, Allen, Ellison and Albrecht). Can this merely be coincidence? One theory, dreamt up in all the spare time enjoyed by the alphabetically disadvantaged, is that the rot sets in early. At the start of the first year in infant school, teachers seat pupils alphabetically from the front, to make it easier to remember their names. So short-sighted Zysman junior gets stuck in the back row, and is rarely asked the improving questions posed by those insensitive teachers. At the time the alphabetically disadvantaged may think they have had a lucky escape. Yet the result may be worse qualifications, because they get less individual attention, as well as less confidence in speaking publicly. The humiliation continues. At university graduation ceremonies, the ABCs proudly get their awards first; by the time they reach the Zysmans most people are literally having a ZZZ. Shortlists for job interviews, election ballot papers, lists of conference speakers and attendees, all tend to be drawn up alphabetically, and their recipients lose interest as they plough through them.

单选题Suppose you have a brick and a sponge which are exactly the same size. The brick and the sponge will occupy the same amount of space, but they will not weigh the same. If two things are exactly the same size, but differ in weight, then they have different densities. The one with the greater weight for the same size has the greater density. The one with lower weight for the same size has the lower density. Now apply this idea to fluids. You know that water and air expand when they are heated and therefore become less dense. If you poured a cupful of very hot water and let it cool, you would have a little less than a cupfull of cool water. If you weighed a cupful of very hot water and a cupful of cool water, the cupful of very hot water would weigh a little less. The cupful of cool water, being a little heavier than the cupful of hot water, would really have a little more water in it. Cold water is denser than hot water. Likewise, cold air is denser than hot. air. The greater weigh! of !he denser material makes it fall to the bottom of the container. It pushes up the less dense material.

单选题According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic (利他主义的)"than at any time in the 17 years of the poll. Not surprising in these hard times, the student's major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job--even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions- be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题Ever since its discovery, Pluto has never really fitted in. After the pale and glowing giant Neptune, it is little more than a cosmic dust mite, swept through the farthest reaches of the solar system on a planet wildly tilted relative to the rest of the planets. It is smaller than Neptune's largest moon, and the arc of its orbit is so oval that it occasionally crosses its massive blue neighbor's path. For years, it has been seen as our solar system's oddest planet. Yesterday, however, scientists released perhaps the most convincing evidence yet that Pluto, in fact, is not a planet at all. For the first time, astronomers have peered into a belt of rocks beyond Pluto unknown until 10 years ago—and found a world that rivals Pluto in size. The scientists posit that larger rocks must be out there, perhaps even larger than Pluto, meaning Pluto is more likely the king of this distant realm of space detritus than the tiniest of the nine planets. When discovered in 1930, "Pluto at that point was the only thing (that far) out there, so there was nothing else to call it but a planet," says Mike Brown, an astronomer at the California Institute of Technology in Pasadena. "Now it just doesn't fit." In one sense, the question of Pluto's planetary status is arcane, the province of pocket-protected scientists and sun-deprived pen pushers determined to decide some official designation for a ball of dust and ice 3 billion miles away. Yet it is also unquestionably something more. From science fair dioramas to government funding, planets hold a special place in the public imagination, and how Pluto is eventually seen—by kids and Congress alike—could shape what future generations learn about this mysterious outpost on the edge of the solar system. The debate has split the astronomical community for decades. Even before the distant band of rocks known as the Kuiper Belt was found, Pluto's unusual behavior made it suspicious. Elsewhere, the solar system fit into near families: the rocky inner planets, the asteroid belt, the huge and gaseous outer planets. Pluto, though, was peculiar. With the discovery of the Kuiper Belt—countless bits of rock and ice left unused when the wheel of the solar system first formed—Pluto suddenly seemed to have cousins. Yet until yesterday, it held to its planetary distinction because it was far larger than anything located there. The rub now is Quaoar (pronounced KWAH-oar), 1 billion miles beyond Pluto and roughly half as large. Named after the creation force of the tribe that originally inhabited the Los Angeles basin, Quaoar forecasts problems for the erstwhile ninth planet, says discoverer Dr. Brown: "The case is going to get a lot harder to defend the day somebody finds something larger than Pluto," To some, the problem is not with Pluto, but the definition of "planet. "In short, there is none. To the Greeks, who coined the term, it meant "wanderer," describing the way that the planets moved across the night sky differently from the stars behind them. Today, with our more nuanced understanding of the universe, the word no longer has much scientific meaning. New York's Hayden Planetarium caused a commotion two years ago by supposedly demoting Pluto, lumping it with the Kuiper Belt objects in its huge mobile of the solar system. In reality, however, the planetarium was making a much broader statement, says Nell Degrasse Tyson, an astrophysicist there. The textbooks of the future should focus more on families of like objects than "planets." The discovery of Quaoar strengthens this idea. "Everyone needs to rethink the structure of our solar system," he says. "We've just stopped counting planets." Still, many are loath to part with the planet Pluto. They note that Pluto, in fact, is distinct from many Kuiper Belt objects. It has a thin atmosphere, for one. It reflects a great deal of light, while most Kuiper Belt objects are very dark. And unlike all but a handful of known Kuiper Belt objects, it has a moon. "Maybe Pluto, then, should be representative of a new class of planets," says Mark Sykes, an astronomer at the University of Arizona in Tucson. "It's the first example, and we are just beginning to find this category./
单选题The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 75 percent hydrogen.
Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic "rays" are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn"t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same.
Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significantly greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning.
However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperatures were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formation of helium went on for only a relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.

The U. S. Bureau has estimated that the
population of the United States could approach 300 million in 2000 and will be
400 million in 2020. And the U. S. Department of Commerce estimates that the
average U.S. per capita income will increase from ＄3400 in 1969 to the
equivalent of＄8300(assuming a 1967 price level) in the year 2000,2.5 times as
much as that of 1969. According to government statistics, in the
United States, there are over 110 million cars and "more people" means "more
cars". By the end of twenties of next century, the population of the United
States will have doubled that of today and the number of automobiles will be
doubled as well. And in twenty-year's time the per capita income will also be
2.5 times higher than it is. If this increase income is spent on more and larger
automobiles, larger houses, and increased consumption of other material goods,
the results could cause catastrophic resource exhaustion, and pollution. Take
the increase of the consumption of oil for instance. The consumption is so huge
that the reserves might last only a decade or two if not supplemented by
imports. Ten years ago it appeared that nuclear power would
solve the anticipated energy crisis. Although supplies of uranium fuel were
known to be limited and might become exhausted in half a century, the nuclear
power plant has for a long time been a favorite project. But work on it has met
with grave problems. The fear of possible atomic explosion and the problem of
disposing of polluting by-product waste have slowed down the construction of
further nuclear plants. Eventually atomic technology may be able to control
these problems, but at present there seems to be little agreement among atomic
scientists about when this can be achieved.
单选题Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient-no matter where he or she may be. Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the university of Kentucky has shown that by using an off-the shelf (现成的) PDA (personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient's vital signs over the telephone. With this kind of equipment in a first- aid kit (急救包), the cry asking whether there was a doctor in the house could well be a thing of the past. Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response-especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise. But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world-CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation internet and third-generation mobile phones for the future of distributed medical intelligence. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in (迎来) an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.
