单选题Directions: There are four passages in the part. Each passage is followed by some questions or unfinished statements. For each of them, there are 4 choices marked A, B, C and D. Read the passages carefully and decide on the best choice. Passage 1 Unless we spend money to spot and prevent asteroids (小行星)now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids (流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth. Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are : 1) How likely the event is ; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It's that simple. " The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New York Times article.

单选题{{B}}Directions: There are five reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blackening the corresponding letter on the answer sheet.{{/B}}{{B}}Passage One{{/B}} You've probably had the experience of having someone fall in love with you when you didn't feel the same way. In such a case it's hard to know what to do. You don't want to be so obvious in your efforts that you make an enemy of him. A friend of mine had this problem and handled it in the most tactful (得体的) way I've ever seen. Instead of telling her admirer directly, she devoted herself to introducing him to every girl she knew. Whenever she had a date with him, she arranged to drop in at the home of one of her girl friends. At last he clicked (一见如故) with one of these girls, and then everyone was happy. My friend was rid of a problem and she still had the young man as a friend, which was just what she wanted him to be. Of course this solution may not work for you. You may have your own way of dealing with the problem. But whatever you decide to do, keep one thing in mind—the boy in question has feelings every bit as sensitive as your own. So try to find a way of discouraging him without hurting him.

单选题Shopping used to be nothing more than a way of obtaining food, clothing and other necessities of life. Today, however, shopping symbolizes the materialistic culture of western society and its popularity as a leisure activity reflects the rise of consumerism.【R1】______Having more money has meant spending patterns have changed. While traditional models of economic behavior assume that consumers are rational and weigh up the costs and benefits before making a purchase, anyone who has ever walked into a shop and left five minutes later with a new jacket and 180 less in their wallet knows that this theory does not always hold true. 【R2】______Her research on consumer behavior identified impulsive buying as an attempt by shoppers to bolster their self-image, particularly for those who suffered from so-called compulsive buying or shopping addiction, a condition that affects 2 to 5 per cent of adults in the West. The three-year study compared excessive buyers to a similar group of ordinary consumers. Excessive shoppers were more materialistic and believed that buying goods was a pathway to success, happiness and identity. " Excessive buying is a coping strategy to fill the gaps between how shoppers feel about themselves and the person they want to be," Dr Dittmar said.【R3】______Her research also reveals that certain types of goods are more likely to be bought on impulse than others. Those most frequently reported—clothes, jewellery, ornaments—are closely related to self-image and appearance. This finding is contrary to usual theories about impulse shopping, which explain it as a short-term gratification winning out over longer-term concerns such as debt. 【R4】______In other words, shoppers were more willing to wait for "low impulse" goods such as kitchenware, than they were for clothes or other "high impulse" items. However, it was found that some of the 60 consumers asked to maintain a shopping diary for the study often regretted their impulsive purchases. Dr Dittmar said, "When people had explicitly bought for self-image reasons, regret was more likely to occur. " But this finding was ambiguous because shopping addicts were more motivated by self-image than ordinary shoppers and were more likely to regret their actions. "It"s not quite clear which way round this relationship goes, but there is a link between being very concerned with self-image goods and regretting impulse buying. " The conclusions drawn by Dr Dittmar about the treatment of compulsive shoppers are that prescribing anti-depressant drugs might solve the problem but only as long as sufferers continue to take them. Instead, they needed therapeutic help to address the underlying causes such as poor self-image. 【R5】______"In no sense do these people directly force anyone to buy anything. But they are very sophisticated, making advertisements and shopping environments very seductive and playing on the idea that if you buy product X you will be much more attractive. "A. Dr. Dittmar said that the idea that consumers" impulsiveness differed, depending on the type of goods, was also supported by the finding that shoppers were less willing to delay gratification for items bought on impulse.B. But there are pitfalls, such as debt and addiction to buying. Addicts shop for shopping"s sake rather than to buy what they need.C. Helga Dittmar, senior lecturer in psychology at Sussex University, has found that consumer goods are the material symbols of who a person is and who they would like to be.D. Her research also raises questions over the methods used to attract shoppers and encourage them to buy. Although advertisers and retailers increasingly appeal to consumers" self-image, Dr Dittmar said it was very difficult to argue that these factors were responsible for compulsive shopping.E. Although there were other ways of dealing with poor self-image, such as over-exercising or alcoholism , she said that shopping had become one of the most important strategies. This was especially true for women, who were three times more likely to be compulsive shoppers than men, as shopping was a socially approved activity, and allowed those who do not go out to work to get out of the house, Dr. Dittmar said.F. Women make the majority of buying decisions—estimates anywhere from 60 - 80% and growing. Despite these facts, some industries have created frustrating walls and barriers failing to cater to the buying characteristics women are looking for.G. This has been made possible by the 75 per cent increase in disposable income in the past 20 years. The number of credit cards in use has more than quadrupled, and the amount of outstanding consumer debt has almost tripled in the same period.

单选题{{B}}Part A{{/B}}{{B}}Directions:{{/B}} Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. (40 points){{B}}Text 1{{/B}} The news from America's housing market is getting no better. As sales declines and defaults and foreclosures climb, pessimists fear that over a million Americans could be driven out of their homes as adjustable-rate mortgages are reset. What should policymakers do? Congress is eager to do more: hence the calls to expand the role of Fannie Mae and Freddie Mac, the giant government-sponsored enterprises (GSES) that tower over America's mortgage market. Fannie's and Freddie's political allies want two things. The first is the raising of the $417,000 limit on the size of loans that the pair may handle. The second demand is the lifting of caps on the amount of mortgages they may buy and hold for themselves. Fannie and Freddie could then ride to the rescue of struggling borrowers, injecting liquidity into parts of the market that have seized up. Their arguments are winning support, and opposition from the Bush administration and the GSES' regulator is softening. Unfortunately, the ideas are likely to do more for Fannie and Freddie than for the mortgage market. Start with the $417,000 limit. Lifting this could help if Fannie and Freddie scoured the upper bracket for borrowers who were struggling but viable. But their history suggests that they would cherry-pick those who could get refinanced elsewhere. And the huge-mortgage market may be correcting itself anyway: spreads over GSE-backed loans, though still unusually high, are falling. It is also riskier. When they hold a mortgage, they take on not only credit risk but also interest-rate and prepayment risk. The loans they guarantee, in contrast, carry only credit risk. So as well as being just as effective, the guarantee business is also safer—and thus better for the taxpayer who unwittingly stands behind the GSES. Moreover, even if they grow no more, the mortgage giants pose a clear systemic threat. Their portfolios of retained mortgages and mortgage-backed securities add up to no less than $1.4 trillion. It is bad enough that this is concentrated in two institutions. No matter how much risk they take or how they manage it, they can borrow at rock-bottom interest rates. If they got into trouble, banks as well as taxpayers would be on the hook. Banks may hold as much GSE debt as they want. Many have amounts that exceed their regulatory capital. The giants were set up decades ago to help banks pool concentrated regional mortgage risk and to make housing more affordable. But as the market has grown deeper and more sophisticated, history has left them behind—hence their desire to get into any bit of the business that will turn a profit. The eventual aim should be to turn them into normal private-sector companies, by stripping them of the charters that give rise to the implicit government guarantees, and break them into smaller pieces.
