单选题A new study by the Development of Health in Taiwan shows that more than half of the adult population in Taiwan lacks an understanding of health problems. More than 2,000 adults took part in the survey to find out about their knowledge of diet, health-care, disease control and medicine. Surprisingly, only 51% of the people surveyed understand that common cold has no cure, and taking medicine is absolutely no use at all. The problem is mad worse by doctors who give their patients large doses of useless drugs. More than two-thirds believe that it is only the nicotine in cigarettes rather than the other chemicals that causes cancer. These people believe that if they smoke “light” cigarettes with less nicotine, they will lead to more illness, suffering and early death. But the outlook for health education in Taiwan is not all negative. The survey concludes that younger Taiwanese have a better understanding of health concerns than their parents, while senior citizens have the least understanding among the three age groups.

单选题The marvelous telephone and television network that has now enmeshed the whole world, making all men neighbors, cannot be extended into space. It will never be possible to converse with anyone on another planet. Even with today's radio equipment, the messages will take minutes—sometimes hours—on their journey, because radio and light waves travel at the same limited speed of 186, 000 miles a second. Twenty years from now you will be able to listen to a friend on Mars, but the words you hear will have left his mouth at least three minutes earlier, and your reply will take a corresponding time to reach him. In such circumstances, an exchange of verbal messages is possible—but not a conversation. To a culture which has come to take instantaneous communication for granted, as part of the very structure of civilized life, this "time barrier" may have a profound psychological impact. It will be a perpetual reminder of universal laws and limitations against which not all our technology can ever prevail. For it seems as certain as anything can be that no signal--still less any material object—can ever travel faster than light. The velocity of light is the ultimate speed limit, being part of the very, structure of space and time. Within the narrow confines of the solar system, it will not handicap us too severely. At the worst, these will amount to twenty hours—the time it takes a radio signal to span the orbit of Pluto, the outer-most planet. It is when we move out beyond the confines of the solar system that we come face to face with an altogether new order of cosmic reality. Even today, many otherwise educated men—like those savages who can count to three but lump together all numbers beyond four—cannot grasp the profound distinction between solar and stellar space. The first is the space enclosing our neighboring worlds, the planets; the second is that which embraces those distant suns, the stars, and it is literally millions of times greater. There is no such abrupt change of scale in the terrestrial affairs. Many conservative scientists, appalled by these cosmic gulfs, have denied that they can ever be crossed. Some people never learn ; those who sixty years ago scoffed at the possibility of flight, and ten years ago laughed at the idea of travel to the planets, are now quite sure that the stars will always be beyond our reach. And again they are wrong, for they have failed to grasp the great lesson of our age— that if something is possible in theory, and no fundamental scientific laws oppose its realization, then sooner or later it will be achieved. One day we shall discover a really efficient means of propelling our space vehicles. Every technical device is always developed to its limit and the ultimate speed for spaceships is the velocity of light. They will never reach that goal, but they will get very near it. And then the nearest star will be less than five years voyaging from the earth.

单选题{{B}}Directions:{{/B}} There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. You're busy filling out the application form for a position you really need, let's assume you once actually completed a couple of years of college work or even that you completed your degree. Isn't it tempting to lie just a little, to claim on the form that your diploma represents a Harvard degree? Or that you finished an extra couple of years back at State University? More and more people are turning to utter deception like this to land their job or to move ahead in their careers, for personnel officers, like most Americans, value degrees from famous schools. A job applicant may have a good education anyway, but he or she assumes that chances of being hired are better with a diploma from a well-known university. Registrars at most well-known colleges say they deal with deceitful claims like these at the rate of about one per week. Personnel officers do check up on degrees listed on application forms, then. If it turns out that an applicant is lying, most colleges are reluctant to accuse the applicant directly. One Ivy League school calls them "impostors". Another refers to them as "special cases". One well-known West Coast school, in perhaps the most delicate phrase of all, says that these claims are made by "no such people". To avoid complete lies, some job-seekers claim that they "attended" or "were associated with" a college or university. After carefully checking, a personnel officer may discover that "attending" means being dismissed after one semester. It may be that "being associated with" a college means that the job-seeker visited his younger brother for a football weekend. One school that keeps records of false claims says that the practice dates back at least to the turn of the century--that's when they began keeping records, anyhow. If you don't want to lie or even stretch the truth, there are companies that will sell you a fake diploma. One company, with officers in New York and on the West Coast, will put your name on a diploma from any number of nonexistent colleges. The price begins at around twenty dollars for a diploma from "Smoot State University". The prices increase rapidly for a degree from the "University of Purdue". As there is no Smoot State and the real school in Indiana is properly called Purdue University, the prices seems rather high for one sheet of paper.

单选题Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form a crust of rock that was many miles thick. Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials. In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart. The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents-and became the several oceans and seas we know today.

单选题When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47- year-old manicurist isn't cutting, filling or polishing as many nails as she'd like to, either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says. "I provide a service that people can do without when they're concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus. "I don't know if other clients are going to abandon me, too", she says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealerships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects, even as they do some modest belt- tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there's a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses," says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant need to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题Eating in space is different from eating on earth. The food that astronauts carry with them does not look like the food you eat. Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship the astronaut puts the water back. He "shoots" hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cake often come in bite-sized pieces. Astronauts can't drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat this way.

单选题Building on the base of evidence and interpretation in Hansen"s (1994) qualitative study of working people"s diaries, we assigned each diarist a set of codes to indicate employment, marital status, number of children, and size of the town in which he or she lived. To analyze the number, location and gender mix of visiting occasions, we coded each day in January and July for every year of the diary, counting the number of named visitors, the visitors" gender, the size of the visiting occasion (1 to 4 people, or 5 and above), the gender mix of those present during the visit, and the location of the visit. While this may seem straightforward at first glance, the variable nature of the diary entries meant that the coding process was not as uncomplicated as we initially anticipated. Given the number of diarists and the span of diary-keeping years, we faced the possibility of coding over 200,000 diary days. Because of the labor-intensive nature of the coding and the number of entries, we chose to code only 2 months—January and July—of each year a diarist kept a diary. We chose 2 months that could reflect a range of sociability. Severe January weather in New England impeded mobility, but it also freed those who were farmers from most of their labor—intensive chores. July tended to be haying season for farmers, which meant some people routinely worked all month in the fields—some alone, some with hired help. Further, the clement July weather meant grater mobility for all of the diary keepers. For some people—those who kept a diary for only a single year—the fact that we coded only 2 months out of each year meant we have only 62 "diary-days" to document their social lives. For others, we have several thousand. Limiting ourselves to January and July for each diary year, we nonetheless coded entries for a total of 24,752 diary days. In an effort to capture an accurate picture of visiting patterns, we coded every day of a given month, even those that had no entry or that mentioned only the weather, as well as those that recorded numerous visiting occasions in one day. Determining a working definition of what constituted a visit was also an unexpected challenge. For example, although schoolteacher Mary Mudge kept a meticulous record of her visiting "rounds," listing names, places, and conversation topics, other diarists were not as forthcoming. A typical entry in farmer John Campbell"s diary (9 July, 1825) was less amenable to our initial coding scheme: "Go to Cart"s for Oxen." (See Hansen and Mcdonald, 1995, for a fuller discussion of the pitfalls of coding diary data.) We therefore created the following coding protocol. We defined a visit as any occasion in which the diarist names the presence of individuals not of his or her household, the presence of the non-household member serving to distinguish between a community interaction and a household interaction. W"e also coded as visits public events at which the diarist was present but others in attendance were not named. The most common among these were records of church attendance. Although an entry "went to church" did not result in a finding of specific male or female visitors, it was a community interaction; thus, these entries were coded as gender-mixed visiting occasions of five or more people in a public place. Because of the variable nature of diary-keeping practices, we were careful to record only what we could confidently infer. Therefore, some entries record visits but no named individuals. Others, such as church attendance (which is generally a large-group event) or a visit to one named friend (which is an intimate affair), allowed us to code the size of the group. Still others, when the location of the visit was specifically mentioned, allowed us to code the diarist as hosting, acting as a guest in another"s home, or interaction at a public place.

单选题 Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water. This special water spider lives on the grassy banks of streams where mosquitoes, damselflies and other insects come to feed and breed. Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn't disturb the water as it waits for its meal, and there is barely a ripple when it skims across the surface at lightning speed to catch its prey. Grass water spiders deal swiftly with larger insects like damselflies by pulling their heads under the water and holding them there until they drown. After a meal, the grass water spider spends up to half an hour grooming itself. It wipes its eight eyes, brushes its antennae, and takes special care to clean the hairs on its body. It is the hairs that trap tiny bubbles of air so that the spider can run down a blade of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater. It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac, which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.

单选题 When he was so far out that he could look back not only on the little bay but past the stretch of rock that was between it and the seashore, he floated on the warm surface and looked for his mother. There she was a line yellow dot under an umbrella that looked like a piece of orange-skin. He swam back to shore, relieved at being sure she was there, but all at once very lonely. On the other side of the bay was a loose scattering of rocks. Above them, some boys were stripping off their clothes. They came running, their bodies bare, down to the rocks. Jerry swam towards them, and kept his distance a little way off. They were off that coast, all of them burned smooth dark brown, and speaking a language he did not understand. To be with them, of them, was a feeling that filled his whole body He swam a little closer: they turned and watched him with narrowed, attentive dark eves. Then one smiled and waved. It was enough nervousness. They shouted cheerful greetings at him, and then, as he preserved his nervous, puzzled smile, they understood that he was a foreigner who had wandered from his own part of the sands and they promptly forgot him. But he was happy. He was with them. They began diving again and again from a high point into a well of blue sea between rough, pointed rocks. After they had dived and come up, they swam round, pulled themselves up, and waited their turn to dive again. They were big boy—men to Jerry. He dived, and they watched him, and when he swam round to take his place they made way for him. He felt he was accepted, and he dived again, carefully, proud of himself. Soon the biggest of the boys balanced himself, shot down into the water and did not come up. The others stood about, watching. Jerry, after waiting for the smooth brown head to appear, let out a cry of warning; they looked at him idly and turned their eyes back towards the water. After a long time, the boy came up on the other side of a big dark rock, letting the air escape suddenly from his lungs with much coughing and spitting, and giving a shout of satisfaction, immediately, the rest of them dived in. One moment the morning seemed full of boys as noisy as a crowd of monkeys; the next, the air and the surface of the water were empty. But through the heavy blue, dark shapes could be seen moving and searching. Jerry dived, shot past the school of underwater swimmers, saw a black wall of rock towering over him, touched it, and shot up at once to the surface, where the rock formed a low wall he could see across. There was no one in sight, under him, in the water; the shadowy shapes of the swimmers had disappeared. Then one and then another of the boys came gap or hole in it. He dived down again. He could see nothing through the stinging salt water but the solid rock. When he came up, the boys were all on the diving rock, preparing to attempt the trick again. And now, overcome with a sense of failure, he shouted up in English: "Look at me! Look!" and he began splashing and kicking in the water like a foolish dog.
