单选题 The Science of the Future Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology. Organic chemistry enables us to produce marvelous synthetic (合成的) materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects. Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans. The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner. It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.

单选题London Cabbies (出租车司机) Every city in the world has taxis to take tourists to interesting places. London is the only city in the world where taking a taxi is an 1 experience for tourists. This is partly because of the special black cabs, which are found in no other country. But it is also because of the drivers themselves. 2 British people are famous for being polite and reserved, London cabbies are well-known 3 their willingness to talk. Some customers say that once the door shuts and the cab 4 off they are a captive (监禁了的) audience. It is impossible to get the taxi driver to stop 5 . "They"re self-confident and free thinking," said Malcolm Linskey, the author of a history of taxi drivers in London. They are also expensive. London has the most expensive taxis of any city in the world except Tokyo. That"s why Ken Livingstone, the Mayor of London, is planning to make taxi drivers negotiate their fares with 6 before they take a ride. Drivers agree that their fares are expensive. That"s because their black taxis 7 more than other cars, they say. And the customer is also paying for more driving expertise (专门知识) than anywhere else in the world. Before someone can qualify as a London taxi driver, that person has to pass a test 8 simply as "The Knowledge" This involves 9 the name and location of every street within six miles of a point in the exact centre of London. The trainee (受训者) must also learn the exact location of every important building within these streets. Finally he or she must be able to use this knowledge to work out the 10 distance between any two destinations within this area. It can 11 up to three years to pass "The Knowledge". Every day it is possible to see trainee taxi drivers on the streets of London, taking careful notes of popular destinations before tracing the route to their next stop. Cab driving is a job often 12 down in families. Many taxi drivers take their children out in their spare time to memorize 13 they need to know when it is their turn to do "The Knowledge". London cabbies also have bigger brains. Recent research found that the part of the brain that remembers things was larger and more 14 in cab drivers. They have to fit the whole of London into their heads, so their brains grow bigger. So perhaps it is not 15 that taxi drivers have lots to say.

单选题{{B}}第二篇{{/B}} {{B}} New Foods and the New World{{/B}} In the last 500 years, nothing about People — not their clothes, ideas, or languages— has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree (可可树) by South American Indians. The Spanish introduced it to the rest of the world during the 1500's. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine (饥荒)" of 1845-1846, and thousands more were forced to leave their homeland and move to America. There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400's. According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the "wide-awake" feeling that one third of the world's population now starts the day with.

单选题Medical Journals Medical journals are publications that report medical information to physicians and other health professionals. In the past, these journals were available only in print. With the development of electronic publishing, many medical journals now have Web sites on the Internet, and some journals are published only online. A few medical journals, like the Journal of the American Medical Association , are considered general medical journals because they cover many fields of medicine. Most medical journals are specialty journals that focus on a particular area of medicine. Medical journals publish many types of articles. Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments. Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature. Because the results of individual research studies can be affected by many factors, combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing, diagnosing or treating a particular disease. Case conferences and ease reports may be published in medical journals to educate physicians about particular illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the authors, often regarding a research or review article published in the same issue. Editorials provide a perspective on how the current article fits with other information on the same topic. Letters to the editor provide a way for readers of the medical journal to express comments, questions or criticisms about articles published in that journal.

单选题{{B}}第三篇{{/B}} {{B}} How Ford Turn Out Cars{{/B}} When it comes to singling out those who have made a difference in all our lives, you cannot overlook Henry Ford. A historian a century from now might well conclude that it was Ford who most influenced all manufacturing, everywhere, even to this day, by introducing a new way to make cars—one, strange to say, that originated in slaughterhouses. Back in the early 1900's, slaughterhouses used what could have been called a "disassembly line. " Ford reversed this process to see if it would speed up production of a part of an automobile engine called a magneto. Rather than have each worker completely assemble a magneto, one of its elements was placed on a conveyer, and each worker, as it passed, added another component to it, the same one each time. Professor David of the University of Delaware, an expert on industrial development, tells what happened: "The previous day, workers carrying out the entire process had averaged one assembly every 20 minutes. But on that day, on the line, the assembly team averaged one every 13 minutes and 10 seconds per person. " Within a year, the time had been reduced to five minutes. In 1913, Ford went all the way. Hooked together by ropes, partially assembled vehicles were towed past workers who completed them on piece at a time. It wasn't long before Ford was turning out several hundred thousand cars a year, a remarkable achievement then. And so efficient and economical was this new system that he cut the price of his cars in half, to $ 260, putting them within reach of all those who, up until that time, could not afford them. Soon, auto makers the world over copied him. In fact, he encouraged them to do so by writing a book about all of his innovations, entitled Today and Tomorrow. The Age of the Automobile has arrived. Today, aided by robots and other forms of automation, everything from toasters to perfumes are made on assembly lines.

单选题Life Connected with Computer After too long on the Net, even a phone call can be a shock. My boyfriend"s Liverpudlian accent suddenly becomes indecipherable after the clarity of his words on screen, a secretary"s tone seems more rejecting than I"d imagined it would be. Time itself becomes fluid—hours become minutes, and alternately seconds stretch into days. Weekends, once a highlight of my week, are now just two ordinary days. For the last three years, since I stopped working as a producer for Charlie Rose, I have done much of my work as a telecommuter. I submit articles and edit them via E-mail and communicate with colleagues on Internet mailing lists. My boyfriend lives in England, so much of our relationship is computer-mediated. If I desired, I could stay inside for weeks without wanting anything. I can order food, and manage my money, love and work. In fact, at times I have spent as long as three weeks alone at home, going out only to get mail and buy newspapers and groceries. I watched most of the blizzard of 96 on TV. But after a while, life itself begins to feel unreal. I start to feel as though I"ve merged with my machines, taking data in, spitting them back out, just another node on the Net. Others online report the same symptoms. We start to strongly dislike the Outside forms of socializing. It"s like attending an A.A. meeting in a bar with everyone holding a half-sipped drink, We have become the Net opponents" worst nightmare. What first seemed like a luxury, crawling from bed to computer, not worrying about hair, clothes and face, has become an avoidance, a lack of discipline. And once you start replacing real human contact with cyber-interaction, coming back out of the cave can be quite difficult. At times, I turn on the television and just leave it to chatter in the background, something that I"d never done previously. The voices of the programs soothe me, but then I"m jarred by the commercials. I find myself sucked in by soap operas, or compulsively needing to keep up with the latest news and the weather. "Dateline," "Frontline", "Nightline", CNN, New York 1, every possible angle of every story over and over, even when they are of no possible use to me. Work moves from foreground to background.
