单选题Here in the U. S. a project of moving the government a few hundred miles to the southwest proceeds apace, under the supervision of Senator Robert Byrd of West Virginia. Apart from the usual highways and parks, Byrd has taken a special interest in transplanting pieces of federal agencies from metropolitan Washington to his home state. Strangely, Byrd's little experiment in de-Washingtonization has become the focus of outrage among the very people who are otherwise most critical of Washington and its ways. To these critics, it is the very symbol of congressional arrogance of power, isolation from reality, contempt for the voters, and so on, and demonstrates the need for term limits if not lynching. Consider the good-government advantages of (let's call it) the Byrd Migration. What better way to symbolize an end to the old ways and commitment to reform than physically moving the government? What better way to break up old bureaucracies than to uproot and transplant them, files and all? Second, spreading the government around a bit ought to reduce that self-feeding and self regarding Beltway culture that Washington-phobes claim to dislike so much. Of course there is a good deal of hypocrisy in this anti-Washington chatter. Much of it comes from politicians and journalists who have spent most of their adult lives in Washington and wouldn't care to live anywhere else. They are not rushing to West Virginia themselves, except for the occasional quaint rustic weekend. But they can take comfort that public servants at the Bureau of the Public Debt, at least, have escaped the perils of inside-the-Beltway insularity. Third, is Senator Byrd's raw spread-the-wealth philosophy' completely illegitimate? The Federal Government and government-related private enterprises have made metropolitan Washington one of the richest areas of the country. By contrast, West Virginia is the second poorest state, after Mississippi. The entire country's taxes support the government. Why shouldn't more of the country get a piece of it? As private businesses are discovering, the electronic revolution is making it less and less necessary for work to be centralized at headquarters. There's no reason the government shouldn't take more advantage of this trend as well. It is hardly enough, though, to expel a few thousand midlevel bureaucrats from the alleged Eden inside the Washington Beltway. Really purging the Washington Culture enough to satisfy its noisiest critics will require a mass exodus on the order of what the Khmer Rouge instituted when they took over Phnom Penh in 1975. Until the very members of the TIME Washington bureau itself are traipsing south along 1-95, their word processors strapped to their backs, the nation cannot rest easy. But America's would-be Khmer Rouge should give Senator Byrd more credit for showing the way.

单选题A complex operation called spinal fusion has emerged as the treatment of choice for many kinds of back pain. But a number of researchers say there is little scientific evidence to show that for most patients, spinal fusion works any better than a simpler operation, the lamineetomy (椎板切除术). Some people would be better off with no surgery at all. Even doctors who favor fusions say that more research is needed on their benefits. In the absence of better data, critics point to a different reason for the fusion operation's fast rise: money. Medicare can pay a surgeon as much as four times more for a spinal fusion as for a laminectomy. Hospitals also collect two to four times as much. "We all cave in to market and economic forces," said Dr. Edward C. Benzel. Though doctors, as a rule, should favor the least complicated treatment—with surgery being the last resort — Dr. Benzel estimated that fewer than half of the spinal fusions done today were probably appropriate. Doctors and hospitals are not the only players with a financial stake in fusion operations. Critics blame the companies that make the hardware for promoting more complex fusions without evidence that they are significantly more effective. Some sort of hardware is used in almost 90 percent of lower-back fusions and the national bill for the hardware alone has soared to $ 2.5 billion a year. The hardware makers acknowledge giving surgeons millions of dollars for consulting and researches, but say the money promotes technical and medical advances that improve back care. But a lawsuit brought by Scott A. Wiese, a former sales representative of Medtronic-the biggest maker of spinal hardware, accused the company of trying to persuade surgeons to use its products with offers of first-class plane tickets to Hawaii and nights at the finest hotels. Medtronic said it did nothing wrong, and it denied the accusations in the lawsuit. But the company disclosed earlier this year that the federal government was investigating charges that it paid illegal kickbacks to surgeons. Federal officials declined to comment on the investigation, and Medtronic said it would vigorously defend itself. Still, between the allure of money and the quest for breakthroughs in treatment, some prominent spinal surgeons say that back care has gone astray.

单选题The Mona Lisa, ______ in Italy, is now in the Louvre, a museum in Paris.

单选题When we think of creative people the names that probably spring to mind are those of men such as Leonardo da Vinci, Albert Einstein, and Pablo Picasso, i.e., great artists, inventors and scientists—a select and exceptionally gifted body of men with rare talent and genius. The tendency to regard creativity and imaginative thinking as the exclusive province of a lucky few disregards the creative and imaginative aspects inherent in the solution of many of the tasks we regularly have to face—the discovery and development of new methods and techniques, the improvement of old methods, existing inventions and products. Everyone has creative ability to some extent. Creative thinking involves posing oneself a problem and then originating or inventing a solution along new and unconventional lines. It involves drawing new analogies, discovering new combinations, and new applications of things that are already known. It follows, then, that a creative person will exhibit great intellectual curiosity and imagination. He will be alert and observant with a great store of information which he will be able to sort out and combine, in the solution of problem. He will be emotionally receptive to new and unconventional ideas and will be less interested in facts than in their implications. Most important of all, he will be able to communicate uninhibitedly and will not be too concerned about other people"s reaction to his apparently "crazy" notions. People called the Wright brothers mad but it did not stop them from becoming the first men to construct and fly a heavier-than-air craft.

单选题I go to the barber every three weeks. I don't like very short hair, so my barber doesn't cut off much. I have known him for almost four years now, and when I go to him, we always talk a lot. He tells me all his news, and I tell him all mine. He meets a lot of interesting people in his shop and he talks to most of them, so he always has a lot of news for me. Every year my barber goes to France for two weeks for his holidays, and when he comes back to England, he has a lot of interesting news. While he is cutting my hair, he tells me about beautiful old cities and quiet little villages, strange food and drinks and many other things. I sit there and listen to the old man with open ears. One minute, my barber's chair is a seat in a French train, and the next minute it becomes a chair in a restaurant in Paris. Although my barber is old, he always tries new things. He never says, "I have never eaten this food before, so I am not going to eat it now." He says instead, "Try everything once./

单选题Many theories concerning the causes of juvenile delinquency (青少年犯罪) focus either on the individual or on society as the major contributing influence. Theories (56) on the individual suggest that children engage in criminal behavior (57) they were not sufficiently penalized for previous misdeeds or that they have learned criminal behavior through (58) with others. Theories focusing on the role of society suggest that children commit crimes in response to their failure to rise above their socioeconomic status (59) as a rejection of middle-class values. Most theories of juvenile delinquency have focused on children from disadvantaged families, (60) the fact that children from wealthy homes also commit crimes.
