填空题Icebergs 1 Icebergs are among nature's most spectacular(壮观的) creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being—somewhere—in faraway, frigid waters, amid thunderous noise and splashing turbulence, which in most case no one hears or sees. They exist only a short time and then slowly waste away(消融) just as unnoticed. 2 Objects of sheerest(最纯粹的) beauty they have been called. Appearing in an endless variety of shapes, they may be dazzlingly white, or they may be glassy blue, green or purple, tinted faintly or in darker hues. They are graceful, stately, inspiring—in calm, sunlight seas. 3 But they are also called frightening and dangerous, and that they are—in the night, in the fog, and in storms. Even in clear weather one is wise to stay a safe distance away from them. Most of their bulk is hidden below the water, so their underwater parts may extend out far beyond the visible top. Also, they may roll over unexpectedly, churning the waters around them. 4 Icebergs are parts of glaciers that break off, drift into the water, float about awhile, and finally melt. Icebergs afloat today are made of snowflakes that have fallen over long ages of time. They embody snows that drifted down hundreds, or many thousands, or in some cases maybe a million years ago. The snows fell in polar regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries. As each year's snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice. When new snow fell on top of the old, it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged into a solid mass of ice.A．Formation of IcebergB．Iceberg Is BeautifulC．Color of IcebergD．Iceberg Is DangerousE. Iceberg Is MysteriousF. Classification of Iceberg

Trade Unions{{/B}} 1．Some scholars have
associated trade unions with the medieval craft guilds(中世纪的行会), but there are
important differences between the two. The guild members were master craftsmen
who owned capital and often employed workers. Unions are known as
associations of workers with similar skills. 2．In the past,
individual workers had no control over the conditions of their working lives;
political and economic power was concentrated in the hands of wealthy business
owners. Workers found, however, that there was strength in uniting. From their
earliest years, union objectives have been higher wages and improved working
conditions. 3．Employers resisted, of course. They made great
efforts to stop union organizing its activities. Union members were fired,
workers were forced to sign contracts in which they promised not to join a
union, and companies hired strikebreakers (破坏罢工者) and even gunmen to frighten
organizers. 4．One of the earliest successful labor organizations
in the United States was the Knights of Labor, founded in 1869. The Knights,
which included both skilled and unskilled workers, attempted to organize all
workers into one great union. After it successfully struck the Wabash railroad
owned by Jay Gould in 1885, its popularity and power grew dramatically. In 1886
the Knights had 700,000 members. 5．The decline of the Knights of
Labor, however, came quickly. The strike against Gould was gradually broken, and
the Knights' radical positions on social issues cost them public support.
In the end, a lack of unity as well as the rapid inflow of unskilled
immigrants weakened the union's economic power, and the organization came to an
end.

填空题 Global Warming1 Smoke is clouding our view of global warming, protecting the planet from perhaps three-quarters of the greenhouse (温室) effect. That might sound like good news, but experts say that as the cover diminishes in coming decades, we are facing a dramatic increase of warming that could be two or even three times as great as official best guesses.2 This was the dramatic conclusion reached last week at a workshop in Dahlem, Berlin, where top atmospheric scientists got together, including Nobel prizewinner Paul Crutzen and Swedish scientist Bert Bolin, former chairman of the UN's Intergovernmental Panel on Climate Change (IPCC).3 IPCC scientists have suspected for a decade that aerosols (浮质) of smoke and other particles from burning rainforest, crop waste and fossil fuels are blocking sunlight and counteracting the warming effect of carbon dioxide (二氧化物) emissions. Until now, they reckoned that aerosols reduced greenhouse warming by perhaps a quarter, cutting increases by 0.2℃. So the 0.6℃ of warming over the past century would have been 0.8℃ without aerosols.4 But the Berlin workshop concluded that the real figure is even higher—aerosols may have reduced global warming by as much as three-quarters, cutting increases by 1.8℃. If so, the good news is that aerosols have prevented the world getting almost two degrees warmer than it is now. But the bad news is that the climate system is much more sensitive to greenhouse gases than previously guessed.5 As those gases are expected to continue accumulating in the atmosphere while aerosols stabilize or fall, that means "dramatic consequences for estimates of future climate change", the scientists agreed in a draft report from the workshop.

1 While everybody enjoys fresh cut flowers around their
house, few people know how to keep them for as long as possible. This may be
done by keeping in mind a few simple facts. 2 An important
thing to remember about cut flowers is that they are sensitive to temperature.
For example, studies have shown that cut carnations(康乃馨) retain their freshness
eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly
harvested flowers at the right temperatures is probably the most important
aspect of flower care. 3 Flowers are not intended by
nature to live very long. Their biological purpose is simply to attract birds or
insects, such as bees, for pollination(授粉). After that, they quickly dry up and
die. The process by which flowers consume oxygen and produce carbon
dioxide(二氧化碳), called respiration(呼吸), generates the energy the flower needs to
give the flower its shape and color. The making of seeds also depends on this
energy. While all living things respire, flowers have a high level of
respiration. A result of all this respiration is heat, and for flowers the level
of heat relative to the mass of the flower is very high. Respiration also brings
about the eventual death of the flower. Thus the greater the level of
respiration, the sooner the flower dies. 4 How, then, to
control the rate at which flowers die? By controlling respiration. How is
respiration controlled? By controlling temperature. We know that respiration
produces heat, but the reverse is also true. Thus by maintaining low
temperatures, respiration is reduced and the cut flower will age more
slowly. 5 Another vital factor in keeping cut flowers is
the quality of the water in which they are placed. Flowers find it difficult to
"drink" water that is dirty or otherwise polluted. Even when water looks and
smells clean, it almost certainly contains harmful substances that can endanger
the flowers. To rid the water of these unwanted substances, household chlorine
bleach (含氯漂白剂)can be used in small quantities. It is recommended that 15 drops
of chlorine bleach( at 4% solution)be added to each liter of water. The water
and solution should also be replaced each day.A．Control of
RespirationB．Beauty of Fresh Cut FlowersC．Role of RespirationD．Most
Important Aspect of Flower CareE. Need for Clean WaterF. Ways of
Stopping Respiration
填空题About Names
Usually, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is "What"s your name?" Everyone gives a different answer, but everyone is correct. Have you ever wondered about people"s names? Where do they come from? What do they mean?
People"s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones. Some people give their children names that mean good things. Clara means "bright"; Beatrice means "one who gives happiness"; Donald means "world ruler"; Leonard means "as brave as a lion".
The earliest last names, or surnames, were taken from place names. A family with the name
Brook or Brooks
probably lived near brook (小溪); someone who was called
Longstreet
probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest. Other early surnames came from people"s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, Smiths were very important workers in every town and village. Some other occupational names are:
Carter
—a person who owned or drove a cart;
Potter
—a person who made pots and pans. The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter"s great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father"s name. English-speaking people added -s or -son. The Johnsons are descendants of John the Roberts family"s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MaeDonnells and the McDonnells and the O" Donnells are descendants of the same Donnell.

填空题A. Major Composer Ludwig yon Beethoven, a major composer of the nineteenth century, overcame many personal problems to achieve artistic greatness. Born in Bonn, Germany, in 1770, he first studied music with the court organist, Gilles van der Eeden. His father was excessively strict and given to heavy drinking. (46) . Appointed deputy court organist to Christian Gottlob Neefe at a surprisingly early age in 1782, Beethoven also played the harpsichord and the viola. In 1792 he was sent to Vienna by his patron, Count Ferdinand Waldstein, to study music under Haydn. Beethoven remained unmarried. (47) Continually plagued by ill health, he developed an ear infection which led to his tragic deafness in 1819. (48) . He completed mature masterpieces of great musical depth: three piano sonatas, four string quartets, the Missa Solemnis, and the 9th Symphony. He died in 1827. (49) . Nothing that Beethoven often flew into fits of rage, Goethe once said of him, "I am astonished by his talent, but he is unfortunately an altogether untamed personality. " (50) . A In spite of this handicap, however, he continued to write music. B Because of irregular payments from his publishers and erratic support from his patrons, he was troubled by financial worries throughout his adult life. C His life was marked by a passionate dedication to independence. D When his mother died, Beethoven, then a young man, was named guardian of his two younger brothers. E Although Beethoven's personality may have been untamed, his music shows great discipline and control, and this is how we remember him best. F Today his music is still being played all over the world.
填空题New Changes in American Life
Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children.
1
But by the middle of this century, men"s and women"s roles were becoming less firmly fixed.
In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture.
2
The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes.
3
Some young men refused to be drafted as soldiers to fight in the war in Vietnam.
In terms of numbers, the counterculture was not a very large group of people.
4
Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on "overtime" work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods.
In the 1970s, the feminist movement, or women"s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers.
5
But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion.
Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations.
A. In addition, many Americans did not value the traditional male role of soldier.
B. Most of them still took traditional women"s jobs as public school teaching, nursing, and secretarial work.
C. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles.
D. But its influence spread to many parts of American society.
E. The people involved in this movement did not value the middle-class American goals.
F. A great many jobs that used to belong to men are now taken by women.
填空题How We Form First Impression 1 We all have first impression of someone we just met. But why? Why do we form an opinion about someone without really knowing anything about him or her-aside perhaps from a few remarks or readily observable traits. 2 The answer is related to how your brain allows you to be aware of the world. Your brain is so sensitive in picking up facial traits, even very minor difference in how a person's eyes, ears, nose. or mouth are placed in relation to each other makes you see him or her as different. In fact, your brain continuously processes incoming sensory information-the sights and sounds of your world. These incoming "signals" are compared against a host of "memories" stored in the brain areas called the cortex system to determine what these new signals-mean. 3 If you see someone you know and like at school, your brain says "familiar and safe". If you see someone new, it says, "new-potentially threatening". Then your brain starts to match features of this stranger with other "known" memories. The height, weight, dress, ethnicity, gestures, and tone of voice are all matched up. The more unfamiliar the characteristics, the more your brain may say, "This is new. I don't like this person". Or else, "I'm intrigued". Or your brain may perceive a new face but familiar clothes, ethnicity, gestures-like your other friends; So your brain says: "I like this person". But these preliminary "impressions" Can be dead wrong. 4 When we stereotype people, we use a less mature form of thinking (not unlike the immature thinking of a very young child) that makes simplistic and categorical impress of others. Rather than learn about the depth and breadth of people-their history, interest, values, strengths, and true character-we categorize them as jocks, geeks, or freaks. 5 However. if we resist initial stereotypical impressions, we have a chance to be aware of what a person is truly like. If we spend time with a person, hear about his or her life, hopes, dreams, and become aware of the person's character, we use a different, more mature style of thinking-and the most complex areas of our cortex, which allow US to be humane.A．Ways of Departure from Immature and Simplistic ImpressionsB．Comment on First ImpressionC．Illustration of First ImpressionD．Comparing Incoming Sensory Information Against MemoriesE．Threatening Aspect of First ImpressionsF．Differences Among Jocks, Geeks and Freaks.
填空题Looking to the Future When a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would "radiate light" and "change color with the push of a button." Food would be replaced by pills. (1) . Cars would have radar. Does this sound like the year 2000? (2) . The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accurately. (3) . But can they? One expert on cities wrote: cities of the future would not be crowded, but would have space for farms and fields. People would travel to work in "airbuses",. large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard of'. Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was "The City of 1982". If the professionals sometimes sound like high-school students, it's probably because future study is still a new field. But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big mistakes in this field, too. (4) . In October of that year, the stock market had its worst losses ever, mining thousands of investors who had put their faith in financial foreseers. (5) In 1957, H. $. Rand of the Rand Corporation was asked about the year 2000, "Only one thing is certain, "he answered. "Children will have reached the age of 43."A. By carefully studying the present, skilled businessmen scientists, and politicians are supposedly able to figure out in advance what will happen.B. School would be taught "by electrical impulse while we sleep."C. One forecaster knew that predictions about the future would always be subject to significant errors.D. In early 1929, most forecasters saw an excellent future for the stock market.E. Everyone may look to the future for it is always promising.E Actually, the article was written in 1958 and the question was, "what will life be like in 19787"

{{B}}How to Argue with Your
Boss{{/B}} Before you argue with your boss, check with the boss'
secretary to determine his mood. If he ate nails for breakfast, it is not a good
idea to ask him for something. Even without the boss' secretary, there are keys
to timing: don't approach the boss when he's on deadline; don't go in right
before lunch, when he is apt to be distracted and rushed; don't go in just
before or after he has taken a vacation. If you're mad, that
will only make your boss mad. Calm down first. And don't let a particular
concern open the floodgates for all your accumulated frustration. The boss will
feel that you think negatively about the company and it is hopeless trying to
change your mind. Then, maybe he will dismiss you. Terrible
disputes can result when neither the employer nor the employee knows what is the
problem the other wants to discuss. Sometimes the fight will go away when the
issues are made clear. The employee has to get his point across clearly in order
to make the boss understand it. Your boss has enough on his mind
without your adding more. If you can't put forward an immediate solution, at
least suggest how to approach the problem. People who frequently present
problems without solutions to their bosses may soon find they can't get past the
secretary. To deal effectively with a boss, it's important to
consider his goals and pressures. If you can put yourself in the position of
being a partner to the boss, then he will be naturally more inclined to work you
to achieve your goals.

Stanford University{{/B}}1 Stanford University,
famous as one of northern California's several institutions of higher learning,
is sometimes called "the Harvard of the West." The closeness of Stanford to San
Francisco, a city thirty-two miles to the north, gives the university a
decidedly cosmopolitan (世界性的) flavor.2 The students are enrolled
mainly from the western United States. But most of the fifty states send
students to Stanford, and many foreign students study here, as well. And
standards for admission remain high. Young men and women are selected to enter
the university from the upper fifteen percent of their high school classes.3
Not only because of the high caliber (素质) of its students but also because
of the desirable location and climate, Stanford has attracted to its faculty
some of the world's most respected scholars. The university staff has included
many Nobel prize winners such as Dr. Felix Bloch, Dr. Robert Hofstadter, and Dr.
William Shockley in physics, Dr. Author Kornberg and Dr. Joshua Lederberg in
medicine, and Dr. Paul J. Flory and Dr. Linus Pauling in chemistry. The Russian
novelist Aleksandr Solzhenistsyn has been in residence. Stanford's undergraduate
school of engineering and its graduate schools of business, law, and medicine
are especially well-regarded.4 What is student life like on "The
Farm"? Culturally, the campus is a magnet for both students and citizens of
nearby communities. Plays, concerts, and operas are performed in the
university's several auditoriums and in its outdoor theater, where graduations
are also held. Several film series are presented during the school year. Guest
lecturers from public and academic life frequently appear on campus. In the
evenings, many students gather to socialize in the Student Union's coffee house;
here the beverages (饮料) and the atmosphere both have a decidedly European
flavor. For the sports-minded, the Stanford campus offers highly developed
athletic facilities. Team sports, swimming, and track and field activity
are all very much part or the Stanford picture. So are bicycling and
jogging.5 In addition to financial support from alumni (校友), Stanford
receives grants from the government and from private philanthropic (慈善的)
foundations. In recent years, government grants have made possible advanced
studies in the fields of history, psychology,, education, and atomic energy. At
present Stanford is carrying out an ambitious building program, financed in part
by the Ford Foundation's 25 million grant. Recently added to the campus are a
new physics building, new school of business, new graduate school of law, new
student union, and undergraduate library.

Teach Your Child Science
1. It is important to make your child interested in science from an early

scientific answers. Don't only give facts but try to give explanations as
well. 2. Science is not just knowledge; it is a way of

the cat out). Of course, you remember there may be a third
explanation. 3. Ask your child to get a piece of string, some
salt, a glass of water and an ice cube (冰块). Tell her to put the ice in the
water, and then put one end of the string on the ice, leaving the other end over
the side of the class. Put a lime salt on the ice. Wait a minute, and then pull
the string, it should be attached to the ice. Ask the child: "what has
happened?" 4. Probably she won't know. Ask her whether fresh
water or salt water freezes into ice first. If you live near the sea and have a
cold winter, she should know fresh water freezes first as she will have seen
that happen. Show her how to test the idea by half-filling two paper cups with
water. Then put them in the icebox and check every three minutes. Write the
results in a table. The conclusion will be that salt changes the behavior of
water, thinking about the string, we see the salt turned some of the ice into
water. Then the salt went away into the water and the ice froze again leaving
the string attached. 5. Then you can ask, "Will water will salt
boil at the same temperature as water without salt?" She can think, tell you her
idea and (taking care the heat) you can test it in the kitchen.
