单选题With China"s growing influence over the global economy, and its increasing ability to project military power, competition between the United States and China is inevitable.【R1】______Most academic analysts are not so sanguine. If history is any guide, China"s rise does indeed pose a challenge to America. Rising powers seek to gain more authority in the global system, and declining powers rarely go down without a fight. And given the differences between the Chinese and American political systems, pessimists might believe that is an even higher likelihood of war. I am a political realist. Western analysts have labeled my political views " hawkish," and the truth is that I have never overvalued the importance of morality in international relations.【R2】______In fact, morality can play a key role in shaping international competition between political powers—and separating the winners from the losers. 【R3】______They were writing in the pre-Qin period, before China was unified as an empire more than 2,000 years ago. It was perhaps the greatest period for Chinese thought, and several schools competed for ideological supremacy andpolitical influence. They converged on one crucial insight; the key to international; influence was political power, and the central attribute of political power was morally informed leadership. Rulers who acted in accordance with moral norms whenever possible tended to win the race fpr leadership over the long term. Over the next decade, China"s leaders must play a larger role on the world stage and offer more security protection and economic support to less powerful countries.【R4】______Such competitionmay cause diplomatic tensions, but there is little danger of military clashes. That"s because future Chinese-American competition will differ from that between the United States and the Soviet Union during the cold war.【R5】______ China"s quest to enhance its world leadership status and America"s effort to maintain its present position is a zero-sum game. It is the battle for people"s hearts and minds that will determine who eventually prevails. And, as China"s ancient philosophers predicted, the country that displays more humane authority will win.A. Neither China nor America needs proxy wars to protect its strategic interests or to gain access to natural resources and technology.B. I came to this conclusion from studying ancient Chinese political theorists like Guanzi, Confucius, Xunzi and Mencius.C. This will mean competing with the United States politically, economically and technologically.D. Leaders of both countries assert optimistically that the competition can be managed without clashes that threaten the global order.E. But realism does not mean that politicians should be concerned only with military and economic might.

单选题Passage Three If you had asked me then if I would accept a job as a restaurant critic for The New York Times, or any established publication, I would have replied, without a second thought, "Of course not!" And not just because I did not want to think of myself as an ambitious sort. Working in restaurants was honest labor; anyone could see that. Writing about them for the mainstream press was not; it felt like joining the enemy. But reviewing was fun, so much fun that when mainstream publishers started paying me for my opinions, I didn't do the decent thing. Before I knew it, I had stopped cooking professionally. Then I stopped cooking altogether. "She's joined the leisure class," my friends said. I disarmed my critics by inviting them along; nobody I knew could afford to eat out and nobody refuseD. We went with equal amounts of guilt and pleasure, with a feeling that we were trespassing on the playgrounds of the rich. We didn't belong in those starchy restaurants. We always got the worst table. And then, because I didn't own a credit card, I had to pay in cash. The year turned into two, and three, and more. I got a credit carD. I got good clothes. I was writing for increasingly prestigious publications. Meanwhile, a voice inside me kept whispering, "How could you?" When I receive weekly letters from people who think it is indecent to write about $100 meals while half the world is hungry, the voice yacks right along. "They're absolutely right," it whispers. And when it asks, "When are you going to grow up and get a real job?" it sounds a lot like my mother. And just about then is when I tell the voice to shut up. Because when my mother starts telling me that all I'm doing with my life is telling rich people where to eat, I realize how much the world has changed. Yes, there are still restaurants where rich people go to remind themselves that they are different from you and me. But there are fewer and fewer of them. As American food has come of age, American restaurants have changeD. Going out to eat used to be like going to the opera; today, it is more like going the movies.

单选题TEXT E 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. Often, however, governments act in an even more harmful way. They actually subsidise the exploitation and consumption of natural resources. A whole range of policies, from farm-price support to protection for coal-mining, do environmental damage and (often) make no economic sense. Scrapping them offers a two-fold bonus: a cleaner environment and a more efficient economy. Growth and environmentalism can actually go hand in hand, if politicians have the courage to confront the vested interest that subsidies create. No activity affects more of the earth's surface than farming. It shapes a third of the planet's land area, not counting Antarctica, and the proportion is rising. World food output per head has risen by 4 per cent between the 1970s and i980s mainly as a result of increases in yields from land already in cultivation, but also because more land has been brought under the plough. All these activities may have damaging environmental impacts. For example, land clearing for agriculture is the largest single cause of deforestation; chemical fertilizers and pesticides may contaminate water supplies; more intensive farming and the abandonment of fallow periods tend to exacerbate soil erosion; and the spread of monoculture and use of high-yielding varieties of crops have been accompanied by the disappearance of old varieties of food plants which might have provided some insurance against pests or diseases in future. Soil erosion threatens the productivity of land in both rich and poor countries. The United States, where the most careful measurements have been done, discovered in 1982 that about one-fifth of its farmland was losing topsoil at a rate likely to diminish the soil's productivity. The country subsequently embarked upon a programme to convert 11 percent of its cropped land to meadow or forest. Topsoil in India and China is vanishing much faster than in America. Government policies have frequently compounded the environmental damage that farming can cause. In the rich countries, subsidies for growing crops and price supports for farm output drive up the price of land. In the late 1990s and early 1990s some efforts were made to reduce farm subsidies. The most dramatic example was that of New Zealand, which scrapped most farm support in 1984. A study of the environmental effects, conducted in 1993, found that the end of fertiliser subsidies had been followed by a fall in fertiliser use (a fall compounded by the decline in world commodity prices, which cut farm incomes). The removal of subsidies also stopped land-clearing and overstocking, which in the past had been the principal causes of erosion. Farms began to diversify. The one kind of subsidy whose removal appeared to have been bad for the environment was the subsidy to manage soil erosion. In less enlightened countries, and in the European Union, the trend has been to reduce rather than eliminate subsidies, and to introduce new payments to encourage farmers to treat their land in environmentally friendlier ways, or to leave it fallow. It may sound strange but such payments need to be higher than the existing incentives for farmers to grow food crops. Farmers, however, dislike being paid to do nothing. In several countries they have become interested in the possibility of using fuel produced from crop residues either as a replacement for petrol (as ethanol) or as fuel for power stations (as biomass). Such fuels produce far less carbon dioxide than coal or oil, and absorb carbon dioxide as they grow. They are therefore less likely to contribute to the greenhouse effect. But they are rarely competitive with fossil fuels unless subsidised and growing them does no less environmental harm than other crops. A result of the Uruguay Round of world trade negotiations is like]y to be a reduction of 36 percent in the average levels of farm subsidies paid by the rich countries in 1986-1990. Some of the world's food production will move from Western Europe to regions where subsidies are lower or nonexistent, such as the former communist countries and parts of the developing world. Some environmentalists worry about this outcome. It will undoubtedly mean more pressure to convert natural habitat into farmland. But it will also have many desirable environmental effects. The intensity of farming in the rich world should decline, and the use of chemical inputs will diminish. Crops are more likely to be grown in the environments to which they are naturally suited. And more farmers in poor countries will have the money and the incentive to manage their land in ways that are sustainable in the long run. That is important. To feed an increasingly hungry world, farmers need every incentive to use their soil and water effectively and efficiently.
