单选题The US $ 3-million Fundamental Physics Prize is indeed an interesting experiment, as Alexander Polyakov said when he accepted this year"s award in March. And it is far from the only one of its type. As a News Feature article in Nature discusses, a string of lucrative awards for researchers have joined the Nobel Prizes in recent years. Many, like the Fundamental Physics Prize, are funded from the telephone-number-sized bank accounts of Internet entrepreneurs. These benefactors have succeeded in their chosen fields, they say, and they want to use their wealth to draw attention to those who have succeeded in science. What"s not to like? Quite a lot, according to a handful of scientists quoted in the News Feature. You cannot buy class, as the old saying goes, and these upstart entrepreneurs cannot buy their prizes the prestige of the Nobels. The new awards are an exercise in self-promotion for those behind them, say scientists. They could distort the achievement-based system of peer-review-led research. They could cement the status quo of peer-reviewed research. They do not fund peer-reviewed research. They perpetuate the myth of the lone genius. The goals of the prize-givers seem as scattered as the criticism. Some want to shock, others to draw people into science, or to better reward those who have made their careers in research. As Nature has pointed out before, there are some legitimate concerns about how science prizes—both new and old—are distributed. The Breakthrough Prize in Life Sciences, launched this year, takes an unrepresentative view of what the life sciences include. But the Nobel Foundation"s limit of three recipients per prize, each of whom must still be living, has long been outgrown by the collaborative nature of modern research—as will be demonstrated by the inevitable row over who is ignored when it comes to acknowledging the discovery of the Higgs boson. The Nobels were, of course, themselves set up by a very rich individual who had decided what he wanted to do with his own money. Time, rather than intention, has given them legitimacy. As much as some scientists may complain about the new awards, two things seem clear. First, most researchers would accept such a prize if they were offered one. Second, it is surely a good thing that the money and attention come to science rather than go elsewhere. It is fair to criticize and question the mechanism—that is the culture of research, after all—but it is the prize-givers" money to do with as they please. It is wise to take such gifts with gratitude and grace.

单选题{{B}}Directions:{{/B}}Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. Most of us would like to be both {{U}}(1) {{/U}} and creative. Why was Thomas Edison able to invent so many things? Was he simply more intelligent than most people? Did he spend long hours toiling away in private? Surprisingly, when Edison was a young boy, his teacher told him he was too {{U}}(2) {{/U}} to learn anything. Other famous people whose creative genius went {{U}}(3) {{/U}} when they were young include Walt Disney, who was fired from a newspaper job because he did not have any good ideas and Enrico Caruso, whose music teacher told him that his {{U}}(4) {{/U}} was terrible. Disney, Edison and Caruso were intelligent and creative men; {{U}}(5) {{/U}}, experts on creativity believe that intelligence is not the same as creativity. Creativity is the ability to think about something in new and unusual ways, and to {{U}}(6) {{/U}} out unique solutions to problems. When creative people are asked what enables them to solve problems in new ways, they say that the ability to find affinities between {{U}}(7) {{/U}} unrelated elements plays a key role. They also say that they have the time and independence in a(an) {{U}}(8) {{/U}} setting to {{U}}(9) {{/U}} a wide range of possible solutions to a problem. How strongly is creativity {{U}}(10) {{/U}} to intelligence? {{U}}(11) {{/U}} most creative people are quite intelligent, the {{U}}(12) {{/U}} is not necessarily true. Many highly intelligent people ({{U}} (13) {{/U}} measured by IQ tests) are not very creative. Some experts remain skeptical that we will ever fully understand the creative process. Others believe that a psychology of creativity is within reach. Most experts agree, {{U}}(14) {{/U}}, that the concept of creativity as {{U}}(15) {{/U}} bubbling up from a magical {{U}}(16) {{/U}} is a myth. Momentary {{U}}(17) {{/U}} of insight, {{U}}(18) {{/U}} by images, make up a {{U}}(19) {{/U}} part of the creative process. At the heart of the creative process are ability and experience that {{U}}(20) {{/U}} an individual's effort, often over the course of a lifetime.

单选题Trying to get Americans to eat a healthy diet is a frustrating business. Even the best- designed public-health campaigns cannot seem to compete with the tempting flavors of the snack-food and fast-food industries and their fat-and sugar-laden products. The results are apparent on a walk down any American street--more than 60% of Americans are overweight, and a full quarter of them are overweight to the point of obesity. Now, health advocates say, an ill-conceived redesign has taken one of the more successful public-health campaigns--the Food Guide Pyramid--and rendered it confusing to the point of uselessness. Some of these critics worry that America' s Department of Agriculture caved in to pressure from parts of the food industry anxious to protect their products. The Food Guide Pyramid was a graphic which emphasizes that a healthy diet is built on a base of grains, vegetables and fruits, followed by ever-decreasing amounts of dairy products, meat, sweets and oils. The agriculture department launched the pyramid in 1992 to replace its previous program, which was centered on the idea of four basic food groups. The" Basic Four" campaign showed a plate divided into quarters, and seemed to imply that meat and dairy products should make up half of a healthy diet, with grains ,fruits and vegetables making up the other half. It was replaced only over the strenuous objections of the meat and dairy industries. The old pyramid was undoubtedly imperfect. It failed to distinguish between a doughnut and a whole-grain roll, or a hamburger and a skinless chicken breast, and it did not make clear exactly how much of each foodstuff to eat. It did, however, manage to convey the basic idea of proper proportions in an easily understandable way. The new pyramid, called" My Pyramid", abandons the effort to provide this information. Instead, it has been simplified to a mere logo. The food groups are replaced with unlabelled, multi-colored vertical stripes which, in some versions, rise out of a cartoon jumble of foods that look like the aftermath of a riot at a grocery store. Anyone who wants to see how this translates into a healthy diet is invited to go to a website, put in their age, sex and activity level, and get a custom-designed pyramid, complete with healthy food choices and suggested portion sizes. This is fine for those who are motivated, but might prove too much effort for those who most need such information. Admittedly, the designers of the new pyramid had a tough job to do. They were supposed to condense the advice in the 84-page United States' Dietary Guidelines into a simple, meaningful graphic suitable for printing on the back of a cereal box. And they had to do this in the face of pressure from dozens of special interest groups--from the country' s Potato Board, which thought potatoes would look nice in the picture, to the Mmond Board of California, which felt the same way about almonds. Even the National Watermelon Promotion Board and the California Avocado Commission were eager to see their products recognized. Nevertheless ,many health advocates believe the new graphic is a missed opportunity. Mthough officials insist industry pressure had nothing to do with the eventual design, some critics suspect that political influence was at work. On the other hand, it is not clear how much good even the best graphic could do. Surveys found that 80% of Americans recognized the old Food Guide Pyramid--a big success in the world of public-health campaigns. Yet only 16% followed its advice.

The majority of people, about nine out of ten, are right-handed.{{U}} (1) {{/U}} until recently, people who were left-handed were considered {{U}}(2) {{/U}}, and once children showed this tendency they were forced to use their right hands.
