第1题：To paraphrase 18th-century statesmanEdmundBurke, "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 of 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 StephenCooper, 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. The author begins his article withEdmundBurke’s words to ______. A、call on scientists to take some actions B、criticize the misguided cause of animal rights C、warn of the doom of biomedical research D、show the triumph of the animal rights movement

第2题：TheAfricans’ interest is to guard preferential export rules enshrined in the temporaryAfrican Growth and OpportunityAct, passed byCongress in 2,000. Tariff-free exports of some 6,000 goods fromAfrica to the United States are boosting trade and investment in southernAfric A、Lesotho’s fast-growing textile industry depends almost entirely onChinese investment in factories to make clothes for sale in the United States. The region also wants more access toAmerica’s markets for fruit, beef and other agricultural goods. American interest lies mainly in SouthAfrica, by far the largest economy in the region. Services account for 60% of its GDP, and it increasingly dominates the rest ofAfrica in banking, information technology, telecom, retail’ and other areas. Just asBritish banks, such asBarclays, have moved theirAfrican headquarters to SouthAfrica over the past year,American investors see the country as a platform to the rest of the continent. Agreeing investment rules and resolving differences on intellectual property rights are the most urgent issues.American drug firms want to be part of the fast expansion in SouthAfrica of production of anti-retroviral drugs, used againstAIDS.By 2007 SouthAfrica alone expects 1.2m patients to take the drugs daily. The country might be the world’s biggest exporter of anti-AIDS drugs within a few years. Striking a bilateral deal now should makeAmerican investments easier. But Mr. Zoellick’s greater concern is for multilateral trade talks that stalled inCancun, Mexico, in September.AlecErwin, his SouthAfrican counterpart, helped to organize the G20 group of poor and middle-income countries that opposed jointAmerican-EU proposals there; he is widely tipped to take over as head of the World Trade Organization late next year, and would be a useful ally. So Mr. Zoellick is trying to charm hisAfrican partner by agreeing to drop support for most of a group of issues (known as "Singapore" issues) that jammed up the talks atCancun, and were opposed by poor countries; he says he also favors abolishing export subsidies inAmerica--though only if Japan and theEU agree to do the same. That would pleaseAfrican exporters who say such subsidies destroy markets for their goods. Mr. Zoellick’s efforts to make more friends may be paying off.Even thoughAmerica has treatedAfrica very shabbily on trade in the past, Mr.Erwin hints it is easier doing business withAmerica than withEurope or Japan. A、small sign, but perhaps a telling one. American drug makers want to get a share in the anti-AIDS drug production in SouthAfrica in that ______. A、the U.S. domestic anti-AIDS drug market is shrinking quickly B、American drug makers have a lot of extra capital to invest C、the bilateral deal has made U.S. investments much easier now D、SouthAfrica has a huge global market potential in these drugs

第7题：When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy. Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu. What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago. Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003. The sentence "After each rain shower, another Internet millionaire sprang up" (Paragraph 1) means ______. A、many people get rich quickly and easily with the NewEconomy B、it takes only the time between showers for someone to become boss C、Seattle’s development is sudden like rain showers D、Seattle has as many business millionaires as its rain showers

第8题：为了保护海边建筑免遭海洋风暴的袭击，海洋度假地在海滩和建筑物之间建起了巨大的防海墙。这些防海墙不仅遮住了一些建筑物的海景，而且使海岸本身也变窄了。这是因为在风暴从水的一边对沙子进行侵蚀的时候，沙子不再向内陆扩展。 如果上述陈述是真的，以下哪项最有可能是真的 A．由于海洋风暴的猛烈程度不断加强，必须在海洋和海边财产之间建立起更多的高大的防海墙。 B．即使是在海滩被人类滥用着的时候，它们对许多使用它们的野生物种的生存来说依然是必不可少的。 C．用来保护海边建筑的防海墙如果要保护那些建筑，它们自己最终不会被风暴破坏，也不需要昂贵的维修和更新。 D．为以后的世代保留下海滩应该是海岸管理的首要目标。 E、对于一个想要维护自己海滩疗养地功能的海边社区来说，通过建筑防海墙来保护海边建筑的努力，从长远来看，其作用是适得其反的。
