第1题：生长在大豆或其他豆类植物根部的根瘤菌能产生固态氮，这是如小麦等其他非豆类庄稼生长不可缺少的植物营养之一，通常它们必须从人造氮肥中得到供给。所以，如果生物技术能成功地使小麦的根部也成为根瘤菌的寄生地，就会减少对人造肥料的需求。 上述论证做了以下哪项假设 A．这种生物技术使小麦根部所产生的根瘤菌必须与豆类植物根部的根瘤菌属于相同的种类。 B．对小麦生长的土壤来说，固态氮是目前必须靠人工肥料来提供的唯一养料。 C．小麦和其他植物根部的根瘤菌寄生地没有天然形成的。 D．豆类植物是目前唯一能自己生产其所需要的固态氮的农作物。 E．生存在小麦根部的根瘤菌将会产生固态氮。

第2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. We can learn from the last paragraph that ______. A、Microsoft has a strong multiplier effect on the economy B、Boeing is crucial for the survival of other companies C、Seattle area’s employment rate has fallen considerably D、the economic foundation of Seattle isBoeing’s continuing prosperity

第9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
