They are in favour of more money being 11 on research into solar, wind and wave energy devices, which could then 12 existing power stations. Some scientists, 13 , believe that even if we stopped 14 carbon dioxide and other gases into the atmosphere tomorrow, we would have to wait several hundred years to 15 the results. Global warming, it seems, is here to stay.

单选题Electric Backpack Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don"t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home. Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers (接收器), night-vision goggles (夜视镜), and other battery-powered devices to get around and do their work. The backpack"s electricity-generating feature could greatly reduce the amount of a wearer"s load now devoted to spare batteries. The backpack"s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The whole pack moves up and down as the person walks. A special mechanism converts movements of the pack to electricity, which can be as much as 7.4 watts. Unexpectedly, tests showed that wearers of the new backpack alter their gaits (步法) in response to the pack"s oscillations (摆动), so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and nonelectric versions of the backpack. The backpack could be especially useful for soldiers, scientists, mountaineers (登山运动员), and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren"t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!

单选题Computers The initial impact of computers was in the area of entertainment. If you walked by a video arcade in the early 1980s, you could not have failed to notice that the use of video games was growing at what some considered an alarming rate. In 1981 the movie industry grossed $ 3 billion, video games took in an estimated $ 6 billion. That gives you some idea of just how big the computer industry had become. Video games employ the same technology as personal computers, and indeed many who bought personal computers did so primarily for playing games at home, thus saving their quarters. Though video games are not as popular as they were a few years ago, they did provide consumer with their first real reason to buy PCs. A more recent computer innovation, desktop publishing, supplies one good reason for those who write for a living to buy a PC. Desktop publishing is a deceptively simple description for an extremely complex group of hardware and software tools. You can now write text, edit text, draw illustrations, incorporate photographs, design page layouts, and print a finished document with a relatively inexpensive computer and laser printer. Although the new technology offers new freedom, there is a price to be paid for this freedom. With total control comes total responsibility. In fact, the issue of social responsibility in our new computer age has long been a topic of debate among computer enthusiasts. Some people are concerned with the long-term social effects of the so-called computer revolution. Ironically, many PC pioneers who built and marketed the first machines were 60s-style advocates of social change. They claim that while personal computer technology has the potential to make society more equal, it's having the opposite effect since upper-middle-class people can afford them and lower-class people cannot. In addition, the ways that computers are used to monitor the activities of their users have evoked anxiety about the machine. Over 7 million Americans now have their work paced, controlled, and monitored by computers. A computer is more restrictive and powerful in the way it controls people than the old-fashioned assembly line. This can lead to what some have called "tech-stress". Irritated eyes, back problems, and other physical symptoms have also been associated with the extensive use of computers. Although the personal computer may not have had the impact some predicted a decade age, the combination of computer technology with satellites and cable does promise innovations in the mass media that would have seemed astonishing just a few short years ago.

单选题Telling Tales about People One of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography. An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. Other writers, such as James Joyce, have written thinly fictionalized accounts of their lives. These are not autobiographies, but they are very close to it. Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently, though, the term memoir seems to be becoming interchangeable with autobiography. A memoir nowadays may or may not deal with the outside world. Biographies are factual accounts of someone else's life. In many senses, these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person, not one that is overly positive or too critical. A fair, well-presented biography may take years to research and write.

单选题Government Policies and Economy While he was off on his 1978 tour, Americans were becoming disgusted with their lot as all "emerging second-class nation", Wilson says. They began to see that incentives had to be restored to the economy. For instance, the capital gains tax was cut, an extraordinary turn-about. If it had been predicted before he went away in May, he would have said it was simply as inconceivable as the prospect of Resorts going up 1 percent. This momentous transformation in the U.S. should soon bring about a huge bull market. In the 1940s and 1950s, the last time price earning multiples were at these low levels, the investing public expected that there would be another great postwar depression. Instead, after the beginning of 1953 it became apparent that there would not be one, and price-earnings multiples got so low this time that investors felt that the country was drifting into socialism. That drift, however, may be reversing direction. Wilson believes that the bankruptcy of New York City means the discrediting of big government, that as a result there will be less government, and that things in general will go much better. From 1980s depressed levels the market could rise to twenty times doubled earnings or almost fivefold in five to seven years. Wilson believes that he"ll be worth hundreds of millions of dollars before it"s over.

单选题The difference between men and women shoppers Shopping for clothes is not the same experience for a man as it is for woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock, the salesman promptly produces it, and the business of trying it on proceeds at once. All being well, the deal can be and often is completed in less than five minutes, with hardly and chat and to everyone's satisfaction. For a man, slight problems many begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else—he offers the nearest he can to the article required. No good salesman brings out such a substitute bluntly; he does so with skill and polish: "I know this jacket is not the style you want, sir, but would you like to try it for size. It happens to be the colour you mentioned. "Few men have patience with this treatment, and the usual response is: "This is the right colour and may be the right size, but I should be wasting my time and yours by trying it on." Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She had never fully made up her mind what she wants, and she is only "having a look round". She is always open to persuasion; indeed she sets great store by what the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lookout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro, often retracing her steps, before selecting the dresses she wants to try on. It is a laborious process, but apparently an enjoyable one. Most dress shops provides chairs for the waiting husbands.
