单选题Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and, more recently, rubber and plastic. And that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. The tool is the laser and it is, being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: Light Amplification by Stimulated Emission of Radiation. As we all know, light is hot; any source of light--from the sun itself down to a humble match burning--will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams have shown researchers that different energy sources produce beams that have a particular effect on certain living cells. It is possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stitches, no unwanted damage--a true surgical wonder. Operations which once left patients exhausted and in need of long periods of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tried. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically.

单选题{{B}}Passage Two{{/B}} According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic (利他主义的) than at any time in the 17 years of the poll. Not surprising in these hard times, the students' major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life." It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job—even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions—be the scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run. But the most important argument for a broad education is that in studying the accumulated wisdom of ages, we improve our moral sense. I saw a cartoon recently which shows a group o businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机) : "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题Most economists in the United States seem excited by the spell of the free market. Consequently, nothing seems good or normal that does not accord with the requirements of the free market. A price that is determined by the seller or, for that matter, established by anyone other than the aggregate of consumers seems harmful. Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both "normal" and having a valuable economic function. In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires. Modern industrial planning requires and rewards great size. Hence, a comparatively small number of large firms will be competing for the same group of consumers. That each large firm will act with consideration of its own needs and thus avoid selling its products for more than its competitors charge is commonly recognized by advocates of free-market economic theories. But each large firm will also act with full consideration of the needs that it has in common with the other large firms competing for the same customers. Each large firm will .thus avoid significant price-cutting, because price-cutting would be prejudicial to the common interest in a stable demand for products. Most economists do not see price-fixing when it occurs because they expect it to be brought about by a number of explicit agreements among large firms; it is not. Moreover, those economists who argue that allowing the free market to operate without interference is the most efficient method of establishing prices have not considered the economies of non-socialist countries other than the United States. These economies employ intentional price-fixing, usually in an overt fashion. Formal price-fixing by cartel and informal price-fixing by agreements covering the members of an industry are commonplace. Were there something peculiarly efficient about the free market and inefficient about price- fixing, the countries that have avoided the first and used the second would have suffered drastically in their economic development. There is no indication that they have. Socialist industry also works within a framework of controlled prices. In the early 1970's. the Soviet Union began to give firms and industries some of the flexibility in adjusting prices that a more informal evolution has accorded the capitalist system. Economists in the Unites States have hailed the change as a return to the free market. But Soviet firms are no more subject to prices established by a free market over which they exercise little influence than are capitalist firms; rather, Soviet firms have been given the power to fix prices.

单选题Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees' errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的)distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 35 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.

单选题{{B}}Text 3{{/B}} The best salespeople first establish a mood of trust and rapport by means of "hypnotic pacing" statements and gestures that play back a customer' s observations, experience, or behavior. Pacing is a kind of mirror-like matching, a way of suggesting: "I am like you. We are in sync. You can trust me." The simplest form of pacing is "descriptive pacing", in which the seller formulates accurate, if banal, descriptions of the customer's experience. "It's been awfully hot these last few days, hasn't it? ... You said you were going to graduate in June." These statements serve the purpose of establishing agreement and developing an unconscious affinity between seller and customer. In clinical hypnosis, the hypnotist might make comparable pacing statements. "You are ham today to see me for hypnosis." "You told me over the phone about a problem that concerns you." Sales agents with only average success tend to jump immediately into their memorized sales pitches or to hit the customer with a barrage of questions. Neglecting to pace the customer, the mediocre sales agent creates no common ground on which to build trust. A second type of hypnotic pacing statement is the "objection pacing" comment. A customer objects or resists, and the sales agent agrees, matching his or her remarks to the remarks of the customer. A superior insurance agent might agree that "insurance is not the best investment out there", just as a clinical hypnotist might tell a difficult subject. "You are resisting going into trance. That's good. I encourage that." The customer, pushing against a wall, finds that the wall has disappeared. The agent, having confirmed the customer's objection, then leads the customer to a position that negates or undermines the objection. The insurance salesperson who agreed that "insurance is not the best investment out there" went on to tell his customer, "but it does have a few uses." He then described all the benefits of life insurance. Mediocre salespeople generally respond to resistance head-on, with arguments that presumably answer the customer's 0biection. This response often leads the customer to dig in his heels all the harder. The most powerful forms of pacing have more to do with how something is said than with what is said. The good salesperson has an ability to pace the language and thought of any customer. With hypnotic effect, the agent matches the voice tone, rhythm, volume, and speech rate of the customer. He matches the customer's posture, body language, and mood. He adopts the characteristic verbal language of the customer. If the customer is slightly depressed, the agent chares that feeling and acknowledges that he has been feeling "a little down" lately. Ill essence, the top sales producer becomes a sophisticated biofeedback mechanism, sharing and reflecting the customer's reality—even to the point of breathing in and out with the customer.
