单选题The Cold Places The Arctic is a polar region. It surrounds the North Pole. Like Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading—125 Fahrenheit below zero. Readings of 85 degrees below zero are common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter is about 73 degrees below zero. One thing alone makes it almost impossible for men to Jive in Antarctica and in parts of the Arctic. This one thing is the low temperature—the killing chili of the far North and the polar South. To survive, men must wear the warmest possible clothing. They must build windproof shelters. They must keep heaters going at all times. Not even for moment can they be unprotected against the below-zero temperature. Men have a way of providing for themselves. Polar explorers wrap themselves in warm coats and furs. The cold makes life difficult. But the explorers can stay alive. What about animals? Can they survive? Do we find plants? Do we find life in the Arctic and the Antarctica? Yes, we do. There is life in the oceans. There is life on land. Antarctica, as we have seen, is a cold place indeed. But this has not always been the case. Expedition scientists have discovered that Antarctica may have been much like our own. Explores have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests. Heat and moisture must have kept the trees in the forests alive.

单选题Sex change surgery guidelines drafted China is set to its first clinical guideline on sex-change Surgery, according to a notice put on the website of the Ministry of Health yesterday. The ministry is now soliciting public and professional 1 on the draft guideline. The coming guideline aims to regulate and standardize sex reassignment surgery, part of a treatment for gender identity disorder in transsexuals. Experts 2 nearly 2,000 Chinese have undergone sex-change surgery while 100,000 to 400,000 are still considering it. However, no official number is available. In the draft, the MOH sets minimum 3 for both surgical candidates and medical institutions. Candidates for the surgery must be older than 20 and single, the draft guideline said. They are also required to prove a persistent 4 for a sex change, to live for at least five consecutive years full-time in the new gender role, and to engage in mental therapy for at least one year. Before surgery can take place, a candidate must receive a recommendation for the operation from a 5 after an appropriate series of therapy sessions. Also, several legal requirements must be met 6 the procedure. The candidate must provide proof from police that he or she has does not have any criminal 7 in the past. Police must also agree to change the sex status on the identity card of the receiver before the 8 can take place. The advent of such a guideline is believed to show that the government is concerned 9 the needs of a relatively small number of people who want to change sex. But doctors also warn 10 all stakeholders, including the hospital and prospective receivers, should be highly cautious about this surgery. The operation is more than a medical 11 due to its-huge social and legal consequences. Doctors should make it clear to those 12 sex-change surgeries that the option always remains to continue to live in the original role. The guideline 13 surgeons to tell patients about other options such as hormone therapy, They are also required to explain the 14 involved, and underlying social barriers including discrimination, and administrative recognition and approval. For the candidates, the surgery itself is not the 15 issue in the long run. The real issue is the kind of life he or she will have to lead afterward.

单选题The Forbidden Apple New York used to be the city that never sleeps. These days, it"s the city that never smokes, drinks or does anything naughty (at least, not in public). The Big Apple is quickly turning into the Forbidden Apple. If you wanted a glass of wine with your picnic in Central Park, could you have one? No chance. Drinking alcohol in public isn"t allowed. If you decided to feed the birds with the last crumbs (碎屑) of your sandwich, you could be arrested. It"s illegal if you went to a bar for a drink and a cigarette, that would be OK, wouldn"t it? Er... no. You can"t smoke in public in New York City. What"s going on? Why is the city that used to be so open-minded becoming like this? The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want, when they want. The press is shocked. Even the New York police have joined the argument. They recently spent $100,000 on a "Don"t blame the cop" campaign. One New York police officer said, "We raise money for the city by giving people fines for breaking some very stupid laws. It"s all about money." The result is a lot of fines for minor offences. Yoav Kashida, an Israel tourist, fell asleep on the subway. When he woke up, two police officers fined him because he had fallen asleep on two seats (you mustn"t use two seats in the subway). Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway. The angry editor of Vanity Fair magazine, Graydon Carter, says, "Under New York city law it is acceptable to keep a gun in your place of work, but not an empty ashtray." He should know. The police came to his office and took away his ashtray (烟灰缸). But not all of the New York"s inhabitants are complaining. Marcia Dugatty, 72, said, "The city has changed for the better. If more cities had these laws, America would be a better place to live." Nixon Patricks, 38, a barman, said, "I like the new laws, if people smoked here, we"d go home smelling of cigarettes." Recent figures show that New York now has fewer crimes per 100,000 people than other U.S. cities. And it"s true—it"s safer, cleaner and more healthy than before. But let"s be honest—who goes to New York for its clean streets?

单选题Global Warming Few people now question the reality of global warming and its effects on the world"s climate. Many scientists put the blame for recent natural disasters 1 the increase in the world"s temperatures 2 convinced that, more than 3 before, the Earth is at risk 4 the forces of the wind, rain and sun. According to them, global warming is making 5 weather events, such as hurricanes and 6 , even more severe and causing sea levels all around the world to 7 . Environmental groups are putting pressure on governments to take action to 8 the amount of carbon dioxide which is given 9 by factories and power plants, thus attacking the problem at its 10 . 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.
