单选题{{B}}Passage Three{{/B}} Predicting the future is risky business for a scientist. It is safe to say, however, that the global AIDS epidemic will get much worse before it gets any better. Sadly, this modern plague will be with us for several generations, despite major scientific advances. As of January 2000, the AIDS epidemic had claimed 15 million lives and left 40 million people living with a viral infection that slowly but relentlessly erodes the immune system. Accounting for more than 3 million deaths in the past year alone, the AIDS virus has become the deadliest microbe in the world. In Africa nearly a dozen countries have a rate higher than 10%, including four southern African nations in which a quarter of the people are infected. This is like condemning 16 000 people each day to a slow and miserable death. Fortunately, the AIDS story has not been all {{U}}gloom and doom{{/U}}. Less than two years after AIDS was recognized, the guilty agent—human immunodeficiency virus, or HIV—was identified. We now know more about HIV than about any other virus, and 14 AIDS drugs have been developed and licensed in the U.S. and Western Europe. The epidemic continues to rage, however, in South America, Eastern Europe and sub-Saharan Africa. By the year 2025, AIDS will be by far the major killer of young Africans, decreasing life expectancy to as low as 40 years in some countries and single-handedly erasing the public health gains of the past 50 years. It is Asia, with its huge population at risk, that will have the biggest impact on the global spread of AIDS. The magnitude of the incidence could range from 100 million to 1 billion, depending largely on what happens in India and China. Four million people have already become HIV-positive in India, and infection is likely to reach several percent in a population of 1 billion. Half a million Chinese are now infected; the path of China's epidemic, however, is less certain. An explosive AIDS epidemic in the U.S. is unlikely. Instead, HIV infection will continue to plague in about 0.5% of the population. But the complexion of the epidemic will change. New HIV infections will occur predominantly in the underclass, with rates 10 times as high in minority groups. Nevertheless, American patients will live quality lives for decades, thanks to advances in medical research. Dozens of powerful and well-tolerated AIDS drugs will be developed, as will novel means to restore the immune system. A cure for AIDS by the year 2025 is not inconceivable. But constrained by economic reality, these therapeutic advances will have only limited benefit outside the U.S. and Western Europe.

单选题 Passage 3 Most worthwhile careers require some kind of specialized training. Ideally, therefore, the choice of an {{U}}(1) {{/U}} should be made even before the choice of a curriculum in high school. Actually, however, most people make several job choices during their working lives,{{U}} (2) {{/U}} because of economic and industrial changes and partly to improve their position. The "one perfect job" does not exist. Young people should {{U}}(3) {{/U}} enter into a broad flexible training program that will fit them for a field of work rather than for a single {{U}}(4) {{/U}}. Unfortunately, etent vocational counselor or psychologist. Knowing {{U}}(5) {{/U}} about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss basis. Some drift from job to job. Others {{U}}(6) {{/U}} to work in which they are unhappy and for which they are not fitted. One common mistake is choosing an occupation for its real or imagined prestige. Too many high-school students--or their parents for them--choose the professional field, {{U}}(7) {{/U}} both the relatively small proportion of workers in the professions and the extremely high educational and personal {{U}}(8) {{/U}}. The imagined or real prestige of a profession or a "White-collar" job is no good reason for choosing it as life's work. Moreover, these occupations are not always well paid. Since a large proportion of jobs are in mechanical and manual work, the {{U}}(9) {{/U}} of young people should give serious consideration to these fields. Before making an occupational choice, a person should have a general idea of what he wants {{U}}(10) {{/U}} and how hard he is willing to work to get it. Some people desire social prestige, others desire intellectual satisfaction. Some want security; others are willing to take risks for financial gain. Each occupational choice has its demands as well as its rewards.

单选题Luckily, the back tires of their car stayed on the road. Otherwise, the young couple would have driven right into a pit twenty feet wide and thirty feet deep! The man and woman were coming home from a party. They were enjoying the landscape around Swansea, Wales. Suddenly, they found the front of their car leaning into a huge hole. The car barely hung onto the edge of the pit. It swayed back and forth like the arm of a balance. In their precarious position, the couple knew that each movement they made could be a matter of life and death. Slowly, slowly, they edged toward the backseat. Then each opened a back door. And on the count of three, they jumped out together. The accident was so scary that they ran a long way before they calmed down. But later they returned to see what had happened. They found that a big chunk of the road had sunk into the ground! And at the bottom of the pit lay their car—roof down and wheels up. Was this mystery of the sunken road ever solved? It turned out that an abandoned mine shaft lay under the road. It had collapsed and taken the pavement with it. Layers of tunnels intersect beneath the city of Swansea. The tunnels were built so many years ago that no one knows where they end or begin. The tunnels are shaky, like those that ants build in the sand. No one knows when the entire city might collapse.

单选题{{B}}Passage 3{{/B}} Monochronic time (M-time) and polychronic time (P-time) represent two variant solutions to the use of both time and space as organizing frames for activities. Space is included because the two systems (time and space) are functionally interrelated. M-time emphasizes schedules, segmentation, and promptness. P-time systems are characterized by several things happening at once. They stress involvement of people and completion of transactions rather than adherence to preset schedules. P-time is treated as much less tangible than M-time. P-time is apt to be considered a point rather than a ribbon or a road, and that point is sacred. Americans overseas are psychologically stressed in many ways when confronted by P-time systems such as those in Latin America and the Middle East. In the markets and stores of Mediterranean countries, one is surrounded by other customers vying for the attention of a clerk. There is no order as to who is served next, and to the northern European or American, confusion and clamor abound. In a different context, the same patterns apply within the governmental bureaucracies of Mediterranean countries: A cabinet officer, for instance, may have a large reception area outside his private office. There are almost always small groups waiting in this area, and these groups are visited by government officials, who move around the room conferring with each. Much of their business is transacted in public instead of having a series of private meetings in an inner office. Particularly distressing to Americans is the way in which appointments are handled by polychronic people. Appointments just don't carry the same weight as they do in the United States. Things are constantly shifted around. Nothing seems solid or firm, particularly plans for the future, and there are always changes in the most important plans right up to the very last minute. In contrast, within the Western world, man finds little in life that is exempt from the iron hand of M-time. In fact, his social and business life, even his sex life are apt to be completely time dominated.

单选题The people of Marseille have a tendency to exaggerate, and you can"t spend long there without hearing the story about the sardine which blocked the old harbour, the Vieux Port. In fact such an event really did occur during the French Revolution, though the obstruction was caused not by a fish of the herring family(for the Vieux Port is about 300 yards wide)but by a ship called the Sardine which was placed there by counter-revolutionaries blockading the insurgents. Or perhaps it was the insurgents who were blockading the counter-revolutionaries: nowadays most people have forgotten the origins of the story entirely, let alone the details, and the sardine which blocked the Vieux Port now exists mainly as a joking example of the Marseillais habit of presenting facts larger than life-size. Almost as much as exaggeration, they like leg-pulling. I was therefore more than a little skeptical when the other day in Marseille I was told that there was a whale on the beach. Initially I dismissed the story as a piece of out-of-season April foolery. But there it was. When we arrived, the coastguards were winching it up onto the jetty with steel hawsers wrapped around the tail. As it was on its back you could easily see the deep folds along the front that identified it as a Rorqual whale: Balenoptera Physalus, according to Madame Turon of the Marseille Museum of Natural History. Being a whale it was, needless to say, enormous. It weighed 10 tons and was 45 feet long. Even so, the poor thing was only a baby. Madame Turon reckoned it was only a year old, for an adult grows to some 70 feet. She said it had died a natural death, probably as much as a month ago, having somehow been separated from its school and succumbed to thirst and hunger. The body was scratched, presumably by having been washed up against rocks, but at first sight seemed to be in a fairly good state. The smell soon told you otherwise, and the temperature that day was well up. It was an event that aroused a mixture of conflicting feelings: fascination and awe at the close-up spectacle of such a magnificent creature; pity at the lack of dignity with which it was being hauled from its element, backwards and up-side down; self-disgust at being part of the crowd of gawping camera-clicking onlookers. We left fairly soon, and were glad to have missed the sequel as recorded in the next day"s papers. The whale was being placed in the back of a large lorry, its tail resting on the cabin, its head hanging off the end. It was then driven to a factory to be cut up for its oils, highly valued in the manufacture of cosmetics. Taking a corner of the Corniche President John Kennedy, its decomposing tongue fell out onto the road. It caused a traffic jam that was unusual even by the standards of Marseille, and one that will doubtless go down in legend along with the sardine that blocked the Vieux Port.

单选题 What are those of us who have chosen careers in science and engineering able to do about our current problems? First, we can help destroy the false impression that science and engineering have caused the current world trouble. On the contrary, science and engineering have made vast contributions to better living for more people. Second, we can identify the many areas in which science and technology, more considerably used, can be of great service in the future than in the past to improve the quality of life. While we can make many speeches, and pass many laws, the quality of our environment will be improved only through better knowledge and better application of that knowledge. Third, we can recognize that much of the dissatisfaction we suffer today results from our very successes of former years. We have been so greatly successful in attaining material goals that we are deeply dissatisfied that we cannot attain other goals more rapidly. We have achieved a better life for most people, but we are unhappy that we have not spread it to all people. We have reduced many sources of environmental disasters, but we are unhappy that we have not conquered of them. It is our raised expectations rather than our failures which now cause our distress. Granted that many of our current problems must be cured more by social, political, and economic instruments than science and technology, yet science and technology must still be the tools to make further advances in such things as clean air, clean water, better transportation, better medical care, more adequate welfare programs, purer food, conservation resources, and many other areas.
