单选题 Why are mobiles so popular? Because people love to talk to each other. And it is easier with a mobile phone. In countries like Russia and China, people use the mobile phone in places where there is no ordinary telephone. Business people, use mobiles when they're traveling. In some countries, like Japan, many people use their mobile phones to send e-mail message and access the Internet. They use a new kind of mobile phone called "i-mode". You can even use a mobile phone to listen to music. Mobile phones are very fashionable with teenagers. Parents buy mobile phones for their children. They can call home if they are in trouble and need help. So they feel safer. But teenagers mostly use them to keep in touch with their friends or play simple computer games. It's cool to be the owner of a small expensive mobile. Research shows that teenage owners of mobile phones smoke less. Parents and schools are happy that teenagers are safer and smoke less. But many people dislike them. They hate it when the businessman opposite them on the train has a loud conversation on his phone. Or when the mobile phone rings in a care or restaurant. But there is a much more serious problem. It's possible that the mobile phone can heat up the brain because we hold the phone so close to our head. Scientists fear that mobiles can perhaps be bad for your memory and even give you cancer.

单选题 Community cancer clusters are viewed quite differently by citizen activists than by epidemiologists. Environmentalists and concerned local residents, for instance, might immediately suspect environmental radiation as the culprit when a high incidence of cancer cases occurs near a nuclear facility. Epidemiologists, in contrast, would be more likely to say that the incidences were "inconclusive" or the result of pure chance. And when a breast cancer survivor, Lorraine Pace, mapped 20 breast cancer cases occurring in her West Islip, Long Island, community, her rudimentary research efforts were guided more by hope that a specific environmental agent could be correlated with the cancers than by scientific method. When epidemiologists study clusters of cancer cases and other noncontagious conditions such as birth defects or miscarriage, they take several variables into account, such as background rate (the number of people affected in the general population), cluster size, and specificity (any notable characteristics of the individual affected in each case). If a cluster is both large and specific, it is easier for epidemiologists to assign blame. Not only must each variable be considered on its own, but it must also be combined with others. Lung cancer is very common in the general population. Yet when a huge number of cases turned up among World War II shipbuilders who had all worked with asbestos, the size of the cluster and the fact that the men had had similar occupational asbestos exposures enabled epidemiologists to assign blame to the fibrous mineral. Although several known carcinogens have been discovered through these kinds of occupational or medical clusters, only one community cancer cluster has ever been traced to an environmental cause. Health officials often discount a community's suspicion of a common environmental cause because citizens tend to include cases that were diagnosed before the afflicted individuals moved into the neighborhood. Add to this the problem of cancer's latency. Unlike an infectious disease such as cholera, which is caused by a recent exposure to food or water contaminated with the cholera bacterium, cancer may have its roots in an exposure that occurred 10 to 20 years earlier. Do all these caveats mean that the hard work of Lorraine Pace and other community activists is for nothing? Not necessarily. Together with many other reports of breast cancer clusters on Long Island, the West Islip situation highlighted by Pace has helped epidemiologists lay the groundwork for a well designed scientific study.

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.

单选题Adam Smith was the first person to see the importance of the division of labor. He gave us an example of the process by which pins were made in England. "One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, and a fifth gives it a head. Just to make the head requires two or three different operations. The work of making pins is divided into about eighteen different operations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them. " Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4800 pins a worker. But if all of them had worked separately and independently without division of labor, they certainly could not have made twenty pins in a day and not even one. There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this, but he also took it for granted that division of labor is itself responsible for economic growth and development and it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new, it only enables people to produce more of what they already have.

单选题 Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 35 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.

单选题The young people who talk of the village as being "dead" are talking nothing but nonsense, as in their hearts they must surely know. No, the village is not dead. There is more life in it now than there ever was. But it seems that "village life" is dead. Gone for ever. It began to decline (衰落) about a hundred years ago, when many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember. What "village life" meant the early years of the present century? It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp-oil and coal. Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed to villagers. The long established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make "village life" and "town life" almost alike. Now with the highly developed science and technology and high-level social welfare for all, there is no point whatever in talking any longer about "village life". It is just life, and that a better life. Finally, if we have any doubts about the future, or about the many changes, which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. Obviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.

单选题Early in the age of affluence (富裕) that followed World War Ⅱ, an American retailing analyst named Victor Lebow proclaimed, "Our enormously productive economy...demands that we make consumption our way of life, that we convert the buying and use of goods into rituals, that we seek our spiritual satisfaction, our ego satisfaction, in consumption.... We need things consumed, burned up, worn out, replaced and discarded at an ever increasing rate." Americans have responded to Lebow's call, and much of the world has followed. Consumption has become a central pillar of life in industrial lands and is even embedded in social values. Opinion surveys in the world's two largest economies—Japan and the United States—show consumerist definitions of success becoming ever more prevalent. Overconsumption by the world's fortune is an environmental problem unmatched in severity by anything but perhaps population growth. Their surging exploitation of resources threatens to exhaust or unalterably spoil forests, soils, water, air and climate. Ironically, high consumption may be a mixed blessing in human terms, too. The time-honored values of integrity of character, good work, friendship, family and community have often been sacrificed in the rush to riches. Thus many in the industrial lands have a sense that their world of plenty is somehow hollow—that, misled by a consumerism culture, they have been fruitlessly attempting to satisfy what are essentially social, psychological and spiritual needs with material things. Of course, the opposite of overconsumption—poverty—is no solution to either environmental or human problems. It is infinitely worse for people and bad for the natural world too. Dispossessed (被剥夺得一无所有的) peasants slash-and-burn their way into the rain forests of Latin America, and hungry nomads (游牧民族) turn their herds out onto fragile African grassland, reducing it to desert. If environmental destruction results when people have either too little or too much, we are left to wonder how much is enough. What level of consumption can the earth support? When does having more cease to add noticeably to human satisfaction?
