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.

单选题{{B}}Text 2{{/B}} If Bill Gates ever had reason to doubt that the brash young billionaires of Google were out to get him, the time for such uncertainty is now officially over. Last month's dramatically revised version of its program Google Desktop is a glove slap across the face of Microsoft's fabled chief software architect. Obviously Google's update to a previous tool that searched people's hard drives in addition to the usual lightning-quick survey of the entire World Wide Web, Google Desktop 2 turns out to be a not-so-stealthy attempt to hijack the desktop from Microsoft. And in a move that must be particularly galling to Gates, the program does it in a way that directly steals thunder from Microsoft's upcoming Windows update, Vista. Specifically, I'm talking about Google's feature called Sidebar, a stack of small windows that sit on the side of the screen and dynamically draw on Web and personal information to track things like weather, stock prices, your e-mail, your photos, recently opened documents and Web destinations . Several years ago, demonstrating an early version of Vista, Microsoft proudly showed a column of on-screen "tiles" that did the same kinds of things. Microsoft's name for this upcoming feature (which it still plans to include in Vista when it ships in late 2006): Sidebar. That's not all. Google product manager Nakhil Bhatla explains that another purpose of Desktop is to use the search box to quickly locate programs and files that you want to open--bypassing the Windows way of clicking on an icon or using the Start menu. Clearly, Google is squatting on Microsoft's turf, asking users to live in its environment as opposed to Bill's. Microsoft still believes that the central point of personal computing is productivity. That's why the desktop search in Vista will limit itself to probing the user's hard disk. Microsoft's explanation for this approach is that mixing Web-search results with hits from your own information is just too confusing. Things go more efficiently, the theory goes, when your personal data pond is segregated from the ocean of information data located elsewhere in the world. (Microsoft offers Web search as a separate program. ) In contrast, Google Desktop searches bring results from everywhere--your hard disk, your email and billions of Web sites. That's because the Google mission is organizing and managing all the world's information. "You shouldn't have to think about where the information comes from," says Google VP Susan Wojcicki. Though Google-sites acknowledge difficulties in merging the personal with the public, their core belief is that the essence of 21st-century computing springs from the connectivity that allows all human knowledge, from books to instant messages, to be potentially shared. As Google tries to annex new information flows, it increasingly runs smack against issues of privacy, copyright and censorship. That's one part of Google's challenge. The other will be fending off Bill Gates, undoubtedly determined to prove that his vision of computing still dominates.

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{{B}}Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.{{/B}}{{B}}Passage One{{/B}} Animals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home. Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation. There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating. One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice. Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators. Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.
