单选题A group of 11 delegates from the Chinese university returned home last week. They came in second place with 13 other university teams. The conference is the world's largest university-level UN simulation. It is held each April, for a week, in New York, to give students a chance to debate international affairs. It is meant to mirror the real-life business of the UN. Teams from more than 23 countries gathered this year to discuss and debate serious issues such as the AIDS epidemic and water shortages. Some UN senior staff members, U. S. professors, and former student participants formed the judge panel. The Chinese team applied to take part in the event and was assigned to represent Japan this year, working on various committees and arguing Japan's position on resolutions to problems like international migration. According to Li Xiaocong, the Chinese team leader, their efforts in finding approaches to resolutions made them stand out. Li attributes their success to "solid training".

单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S. had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show off technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms (隐约出现) as humanity's next great terra incognita (未探明之地). And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: are there experiments that only humans could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.

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Passage One To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling, out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is tested in animals--no meat, no fur, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don't understand. Scientists must communicate their message to the public in a compassionate, understandable way—in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation, a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

单选题 There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to five children something to do. In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks o~ their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all part of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arctic (北极的) peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent (进步). The progress from a rattle (拨浪鼓) used by a baby in 3000 B.C. to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.

单选题In 1985 when a Japan Air Lines (JAL) jet crashed, its president, Yasumoto Takagi, called each victim"s family to apologize, and then promptly resigned. And in 1987, when a subsidiary of Toshiba sold sensitive military technology to the former Soviet Union, the chairman of Toshiba gave up his post. These executive actions, which Toshiba calls "the highest form of apology", may seem bizarre to US managers. No one at Boeing resigned after the JAL crash, which may have been caused by a faulty Boeing repair. The difference between the two business cultures centers around different definitions of delegation. While US executives give both responsibility and authority to their employees, Japanese executives delegate only authority—the responsibility is still theirs. Although the subsidiary that sold the sensitive technology to the Soviets had its own management, the Toshiba top executives said they "must take personal responsibility for not creating an atmosphere throughout the Toshiba group that would make such activity unthinkable, even in an independently run subsidiary. " Such acceptance of community responsibility is not unique to businesses in Japan. School principals in Japan have resigned when their students committed major crimes after school hours. Even if they do not quit, Japanese executives will often accept primary responsibility in other ways, such as taking the first pay cut when a company gets into financial trouble. Such personal sacrifices, even if they are largely symbolic, help to create the sense of community and employee loyalty that is crucial to the Japanese way of doing business. Harvard Business School professor George Lodge calls the ritual acceptance of blame "almost a feudal (封建的) way of purging (清除) the community of dishonor", and to some in the United States, such resignations look cowardly. However, in an era in which both business and governmental leaders seem particularly good at evading responsibility, many US managers would probably welcome an infusion (灌输) of the Japanese sense of responsibility. If, for instance, US automobile company executives offered to reduce their own salaries before they asked their workers to take pay cuts, negotiations would probably take on a very different character.
