单选题Violin prodigies, I learned, have come in distinct waves from distinct regions. Most of the great performers in the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Isaac Stern, one of the world's greatest violinists the reason for this phenomenon. "It is very clear," he told me. "They were all Jews(犹太人)and Jews at the time were severely oppressed and ill-treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage. " As a result, every Jewish parent's dream was to have a child in the music school because it was a passport to the West. Another element in the emergence of prodigies, I found, is a society that values excellence in a certain field to nurture(培育)talent. Nowadays, the most nurturing societies seem to be in the Far East. "In Japan, a most competitive society, with stronger discipline than ours. " says Isaac Stem, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War II , that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese. That's a good thing, because even prodigies must work hard. Next to hard work, biological inheritance plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.

Dear Sirs, Given all the coverage that the emergence of hybrid cars has received in your pages in recent months, your readers may be interested to learn that gasoline-electric hybrids are not a new phenomenon at all, but rather the latest incarnation of an idea that has been kicking around for over a century. Indeed, the hybrid car has been around almost as long as the automobile itself. At the turn of the twentieth century, as the automotive age dawned, three power-generating technologies competed for dominance: steam, gasoline, and electricity. In the year 1900, steam was well known as the power source of the industrial revolution, and electricity was widely regarded as the power source of the future, so it was not at all obvious that internal combustion engines burning a fractional distillate of crude petroleum would have any particular edge in this race for the powertrains of America. Indeed, when engineer H. Piper filed the first patent application for a gasoline-electric hybrid motor in 1905, his intention was to use the gas to give a little kick to his perfectly serviceable electric engine. His goal: an engine that could accelerate from 0 to 25 miles per hour in 10 seconds. Piper achieved his goal. Electric and hybrid-electric engines powered more than 35,000 vehicles sold in 1912. These cars were perfectly adequate for the time, but over the following decade they mostly disappeared from the market, through no fault of their own. The cause of their decline was the spectacular improvements in the cost and performance of gasoline-powered cars. An onslaught of fast and cheap internal combustion cars from Ford, General Motors, and Buick essentially buried the electric and electric-hybrid motors by the 1920s. Continuing performance improvements in internal combustion engines and inexpensive gas pretty much kept hybrids buried until the oil crises of 1973 and 1979 gave Americans a reason to start thinking about fuel efficiency. Engineers had the motivation to think about fuel-efficient hybrids, but they still lacked the means to make hybrids economically competitive with gas-powered cars, because the performance of gas-electric engines lagged far behind that of gas-powered engines in acceleration, top speed, and cruising range. Dramatic improvements in electronics and computer technology during the 1990s, however, finally made the hybrid a reality. Advances in battery performance and, most importantly, computer-guided electric power transfer created a car that could drive like a regular car, but do so on half the tank of gas. As another century dawns, perhaps we are entering into a new automotive age.

单选题Does using a word processor affect a writer s style? The medium usually does do something to the message after all, even if Marshall McLuhan' s claim that the medium simply is the message has been heard and largely forgotten now. The question matters. Ray Hammond, in his excellent guide The Writer and the Word Processor, predicts that over half the professional writers in Britain and the USA will be using word processors by the end of 1985. The best known recruit is Leu Deighton, from as long ago as 1968, though most users have only started since the microcomputer boom began in 1980. Ironically word processing is in some ways psychologically more like writing in rough than typing, since it restores fluidity and provisionality to the text. The typist' s dread of having to get out the Tippex, the scissors and paste, or of redoing the whole thing if he has any substantial second thoughts, can make him consistently choose the safer option in his sentences, or let something stand which he knows to be unsatisfactory or incomplete, out of weariness. In word processing the text is loosened up whilst still retaining the advantage of looking formally finished. This has, I think, two apparently contradictory effects. The initial writing can become excessively sloppy and careless, in the expectation that it will be corrected later. That crucial first inspiration is never easy to recapture, though, and therefore, on the other hand, the writing can become over - deliberated, lacking in flow and spontaneity, since revision becomes a larger part of composition. However, these are faults easier to detect in others than in oneself. My own experience of the sheer difficulty of committing any words at all to the page means I' m grateful for all the help I' can get. For most writers, word processing quite rapidly comes to feel like the ideal method ( and can always be a second step after drafting on paper if you prefer). Most of the writers interviewed by Hammond say it has improved their style ( "immensely", says Deighton). Seeing your own word on a screen helps you to feel cool and detached about them. Thus is not just by freeing you from-the labor of mechanical retyping that a word processor can help you to write. One author (Terence Feely) claims it has increased his output by 400%. Possibly the feeling of having a reactive machine, which appears to do things, rather than just have things done with it, accounts for this--your slave works hard and so do you. Are there no drawbacks? It costs a lot and takes time to learn--" expect to lose weeks of work", says Hammond, though days might be nearer the mark. Notoriously it is possible to lose work altogether on a word processor, and this happens to everybody at least once. The awareness that what you have written no longer' exists anywhere at all, is unbelievably enraging and baffling. Will word processing generally raise the level of professional writing then? Does it make writers better as well as more productive? Though all users insist it has done so for them individually, this is hard to believe. But reliance happens fast.

单选题Charles Paul and his wife, Hazel, stopped using the motor home they bought several years ago; it sits idle behind their house in Richardson, Texas. Travel is just one sacrifice they made to pay for the cost of their prescriptions, more than a dozen medications for the two of them. They found relief by switching drugstores, to one in nearby McKinney. A prescription for Paul"s diabetes had cost $89.88 when he got it from a national chain but dropped down to $58 from McKinney"s Smith Drug. Smith, which claims to be the oldest drugstore in Texas, has been getting a lot of attention since a Dallas newspaper touted its astoundingly low prices. The overwhelming response from the public has been "a little scary," says co-owner Kaylei Mosier. She says the store simply marks each prescription up enough to cover its costs, but for many prescriptions that"s a lot lower than at other stores. The Smith Drug story has highlighted a little-known fact: prescription prices vary from city to city and block to block, and a little research can save consumers hundreds or thousands of dollars. Insurance copays can make these differences invisible, but they"re a huge deal to the 45 million uninsured Americans. Why the price swings? Howard Schiff, executive director of the Maryland Pharmacists Association, explains that pharmacies generally buy their drugs from a wholesaler, who doesn"t sell to every drugstore at the same price. Once the drug is in the pharmacy, each owner chooses how much to mark it up. Because fewer than 10 percent of consumers comparison-shop for prescriptions the way they might for a quart of milk—and drug prices generally are not advertised—pharmacies don"t worry that higher prices will drive people away, says Stanford economist Alan Scorensen. There is a downside to hopping from drugstore to drugstore. If people price-shop, they"re going to lose some protection that comes from having one pharmacy track all your medications. Going to many pharmacies keeps one pharmacist from noticing potentially harmful interactions between prescriptions. Comparison-shopping is further complicated because pharmacies that have the best price on one drug don"t usually have the lowest prices across the board, so finding a good price on one drug at a pharmacy does not guarantee a cheaper total bill.

单选题{{B}}Passage 3{{/B}} The U. S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. {{U}}The areas of the map where earthquakes are most likely to occur are called earthquake "belt".{{/U}} The government is. spending a great deal money and is working hard to help discover the answer to these two questions: ① Can we predict earthquakes? ② Can we control earthquakes? To answer the first question, scientists are looking very closely at the most active fault (断层)systems in the country, such as the San Andreas fault in California. A fault is break between two sections of the earth's surface. These breaks between sections are the place where earthquake occurs. Scientists look at the faults for changes that might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately. And the control of earthquakes is even farther away. Nevertheless, there have been some interesting developments in the field of controlling earthquakes, The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was put into a layer of rocks 4000 meters below surface of the ground. Shortly after this injection of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into rocks works like oil on each other. When the water "oiled" the fault, the fault became slippery and the energy of an earthquake was released. Scientists are still experimenting at the site of these earthquakes. They have realized that there is a Connection between injection of the water and the earthquake activity. They have suggested that might be possible to use this knowledge to prevent very big destructive earthquakes, that is, scientists could inject some kind of fluid like water into faults and change the big earthquake into a number of small, harmless earthquakes.
