单选题{{B}}Passage One{{/B}} "Humans should not try to avoid stress any more than they would shun food, love or exercise." said Dr. Hans Selye, the first physician to document the effects of stress on the body. While here's no question that continuous stress is harmful, several studies suggest that challenging situations in which you're able to rise to the occasion can be good for you. In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they couldn't get the job done. Stress that you can manage may also boost immune(免疫的)function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects believed they had control over the outcome. In the second, they weren't in control: They had to sit through a gory(血淋淋的)video on surgical procedures. Those who did go on the memory test had an increase in levels of immunoglobulin(免疫球蛋白)A, an antibody that's the body's first line of defense against germs. The video-watchers experienced a downturn in the antibody. Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. "They can help nerve cells handle information and put it into storage," says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain. "Sustained stress is not good for you," says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity (长寿),"It's the occasional burst of stress or brief exposure to stress that could be protective.

单选题Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most distant areas can now follow state affairs, see and hear the politicians before an election. Better informed, people are more likely to vote, and so to make their opinion count. Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are less patient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen.

单选题The domestic economy in the United States expanded in a remarkably vigorous and steady fashion. The revival in consumer confidence was reflected in the higher proportion of incomes spent for goods and services and the marked increase in consumer willingness to take on installment debt. A parallel strengthening in business psychology was manifested in a stepped-up rate of plant and equipment spending and a gradual pickup in expenses for inventory. Confidence in the economy was also reflected in the strength of the stock market and in the stability of the bond market. For the year as a whole, consumer and business sentiment benefited from the ease in East-West tensions. The bases of the business expansion were to be found mainly in the stimulative monetary and fiscal policies that had been pursued. Moreover, the restoration of sounder liquidity positions and tighter management control of production efficiency had also helped lay the groundwork for a strong expansion. In addition, the economic policy moves made by the President had served to renew optimism on the business outlook while boosting hopes that inflation would be brought under more effective control. Finally, of course, the economy was able to grow as vigorously as it did because sufficient leeway existed in terms of idle men and machines. The United States balance of payments deficit declined sharply. Nevertheless, by any other test, the deficit remained very large, and there was actually a substantial deterioration in our trade account to a sizable deficit, almost two-thirds of which was with Japan. While the overall trade performance proved disappointing, there are still good reasons for expecting the delayed impact of devaluation to produce in time a significant strengthening in our trade picture. Given the size of the Japanese component of our trade deficit, however, the outcome will depend importantly on the extent of the corrective measures undertaken by Japan. Also important will be our own efforts in the United States to fashion internal policies consistent with an improvement in our external balance. The underlying task of public policy for the year ahead—and indeed for the longer run—remained a familiar one: to strike the right balance between encouraging healthy economic growth and avoiding inflationary pressures. With the economy showing sustained and vigorous growth, and with the currency crisis highlighting the need to improve our competitive posture internationally, the emphasis seemed to be shifting to the problem of inflation. The Phase Three program of wage and price restraint can contribute to reducing inflation. Unless productivity growth is unexpectedly large, however, the expansion of real output must eventually begin to slow down to the economy's larger run growth potential if generalized demand pressures on prices are to be avoided.

单选题Passage Three How can a company improve its sales? One of the keys to more effective selling is for a company to first decide on its "sales strategy". In other words, what is the role of the sales person? Is the salesperson's job narrative, suggestive, or consultative? The "narrative" sales strategy depends on the salesperson moving quickly into a standard sales presentation. His or her pitch highlights the benefits for the customer of a particular product or service. This approach is most effective for customers whose buying motives are basically the same and is also well suited to companies who have a large number of prospects (可能的主顾) on which to call. The "suggestive" approach is tailored more for the individual customer. The salesperson must be in a position to offer alternative recommendations that meet a particular customer's needs. One key aspect of the suggestive approach is the need for the salesperson to engage the buyer in some sort of discussion. The salesperson can then use the information gleaned from the customer to suggest an appropriate product or service. "We tell our salespeople to be like wine stewards," says Mindy Sahlawannee, a corporate sales trainer. "The wine steward first checks to see what food the custoiner has ordered and then opens by suggesting the wine that best complements the dish. Most companies who use a narrative strategy should be using a suggestive strategy. Just like you can't drink red wine with every dish, you can't have one sales recommendation to suit all customers." The final strategy demands that a company's sales staff act as "consultants" for the buyer. In this role, the salesperson must acquire a great deal of information about the customer. They do this through market research, surveys, and face-to-face discussions. Using this information, the salesperson makes a detailed presentation tailored specifically to a customer's needs. "Good sales 'consultants'," says Alan Goldfarb, president of Ad Pro, Inc., "are the people who use a wide range of skills including probing, listening, analysis, and persuasiveness. The best sales 'consultants', however, are the ones who can 'think outside the box and use their creativity to present a product and close the sale. The other skills you can teach. Creativity is innate. It's something we look for in every employee we hire." More and more sales teams are switching from a narrative or suggestive approach to a more consultative strategy. As a result, corporations are looking more at intangibles such as creativity and analytical skills and less at educational background and technical skills. "The next century will be about meeting individual customer needs," says Goldfarb. "The days when one size fits all are over./

单选题{{B}}Passage Two{{/B}} Nick was tired of life. Every day was exactly the same. "What I need is a little adventure!" Nick thought as he waited at the bus stop one morning. Nick's little adventure happened sooner than he had expected! While he was on the bus, reading his newspaper, the man sitting next to him suddenly pushed a large brown envelope in his hands. "Here, take this!" he murmured. Then he stood up and got off the bus before Nick could say a word. Nick sat There holding the envelope. It felt heavy. There were papers inside, or money perhaps. "I'd better hand it over to the police." He thought. There was a police station close to his office. But as he got off the bus, a man came up to him. He was obviously waiting for something. "He wants the envelope." Nick thought. Nick began to walk quickly and the man hurried after him. Nick started to run and the man began to run, too. But then, just before he go to the police station, Nick managed to lose the man in the crowds when he entered the police station, the man was no longer in sight. Inside the police station, the envelope was full of money—false money. "Obviously the man made a mistake." the inspector said, "He thought you was one of the gang! Well congratulations!" Nick felt like a hero. He could already see his name in all the paper. He could imagine an interview on television ! "However," the inspector went on, interrupting Nick's daydreams. "I'm afraid I must ask you to keep quiet about this. We're trying to catch some very clever thieves, and we don't want them to know that we have some of the money. So you mustn't say a word to anyone—even your boss! Sorry!" "So that's that!" Nick said to himself on his way to the office. He was over an hour late. "I've had my little adventure, but I can't tell anyone about it. So what's the point? I've even to make up an excuse to the boss!"

单选题{{B}}Passage Four{{/B}} She was slim and he liked her that way. So he called a lawyer. The result was a contract. According to the document, the fresh-faced bride agreed to pay a fine for each pound she gained in weight, the money refundable upon its loss. The paper signed, and the wedding went on. This is a prenuptial (婚前的)agreement—one more indication of the strange pass of marriage in this most transactional decade. You are welcome to marriage, contractual style, where increasingly detailed legal documents spell out everything from who's going to do the dishes to who's going to get the house when you split. This is family planning taken to extreme. Once employed solely by the rich, second-timers and the old industrialist carrying off the latest young cookie, the prenuptial agreement—a written pact between a couple outlining the financial obligations in the event of divorce—is becoming commonplace in a litigious (爱打官司的),disillusioned and materialistic age in which one in every two marriages is projected to end in divorce. The only question is: What about love? When asked whether anyone believes in Cupid (爱神)anymore, Dr. Michael Vincent Miller says, "Given a century that is full of sexual liberation, computer-dating services and so on, one feels tempted to reply,' only in a mood of desperate nostalgia (怀旧 )'. ""Pre-nups" (prenuptial agreements)do assume negativity. Founded on disillusionment, they cannot be separated from the high divorce rate in the United States. The result, argues Miller, is a kind of defending mentality. "We've gotten good at managing finiteness, failure and trouble with a sort of 'What' s yours is yours and what's mine is mine's realism'. We've seen it isn't all about love. We've seen there's power politics in there—a fight for control, and when you've got those things, you're halfway to lawyers and money." In other ways, however, the compacts embody positive, even idealistic thinking about marriage, love and relations, a law scholar Isabel Marcus believes. Marcus says , "Contracts could spell the end of romantic love as salvation. They say love exists, but that it's best accompanied by good, hard thinking about equitability (平等). By writing a contract, the couple gains control of its marriage. "What's good is it contributes to honesty; what's unfortunate is the idea that any contract can govern your emotions," says the author of the book "The Nature of Love."
