第8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. Mr. Zoellick is trying to establish a good relationship with Mr.Erwin because ______. A、Mr.Erwin is organizing a group of, poor and middle-income countries to opposeAmeric A、 B、Mr.Erwin is a very talented and tactful diplomat in the world political circle C、Mr.Erwin’s possible position in the coming future will be helpful toAmerican interests D、Mr.Erwin’s relationship with Japanese andEuropean leaders is useful to the U.S.

第9题：To be a good friend, you have to give of yourself, nonetheless not so much that you lose yourself. This is a pretty predictable recipe for happiness. Giving to others—a reliable way of fostering friendships—makes us happier than taking things for ourselves. In the light of research led byDr.ElizabethDunn at the University ofBritishColumbia, money can purchase happiness...on the prerequisite that you utilize it on other people. Researchers administered three studies consecutively. First, they surveyed more than 600Americans and found that spending money on gifts and charities led to greater happiness than spending money on oneself. Subsequently they probed into workers who had just received bonuses and observed that their happiness did not hinge on the size of their bonus but on the decision they made about what to do with whatever amount of money they receiveD、Those who spent more of their bonus on others were happier than those who spent the money on themselves. Finally, the researchers simply distributed money to a good many subjects, instructing some to spend the money on themselves and others to spend the money on others.At the end of the day, the ones who spent money on others were a good deal happier. As a consequence, having friends and treating them generously is clearly a winning strategy in life.But what about in business If you watch even a single episode of any reality TV show based on a competition, such as TheApprentice, you’ll hear a single phrase crop up more often than any other: "I’m not here to make friends!" Is that trueAre we better off being cutthroat than collaborative Once you’re on the job, having a best friend at work is a strong predictor of ensuing success. People might define "best" loosely (think of this as kindergarten where you can have more than one "best" friend), but according to a Gallup Organization study of more than 5 million workers over 35, 56% of the people who say they have a best friend at work are engaged, productive, and successful while only 8% of the ones who don’t are. Another remarkable study, spanning decades, revealed that friendships in high school were an effective predictor of increased wages in adulthood—to the tune of 2% per person who considered you a close frienD、To put it otherwise, if in high school three people regarded you as one of their closest same-sex friends, your earnings in adulthood work would be 6% higher. The happy truth is that the competitors who say they’re not here to make friends don’t win eventually. That’s true for reality TV, for business, and for life as well. The author quotes the example of the TV show to show that______. [A] it is not possible to find friends during a competition [B] it is improper to talk about friendship on TV [C] friendship is of much importance even in business [D] there is no chance for competitors to cooperate during TV shows

第10题：The role of governments in environmental management is difficult but inescapable. Sometimes, the state tries to manage the resources it owns, and does so badly.

World food output per head has risen by 4 per cent between the 1970s and 1980s mainly as a result of increases in (8) from land already in (9) , but also because more land has been brought under the plough. Higher yields have been achieved by increased irrigation, better crop breeding, and a (10) in the use of pesticides and chemical fertilizers in the 1970s and 1980s. All these activities may have (11) environmental impacts. For example; land clearing for agriculture is the largest single (12) of deforestation; chemical fertilizers and pesticides may (13) water supplies; more intensive farming and the abandonment of fallow periods (14) exacerbate soil erosion; and the spread of monoculture and use of high-yielding varieties of crops have been accompanied by the (15) of old varieties of food plants which (16) some insurance against pests or diseases in future. Soil erosion threatens the productivity of land in both rich and poor countries.
