单选题Climate Change Poses Major Risks for Unprepared Cities A new examination of urban policies has been (51) recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and (52) development. She warns that many of the world's fast-growing urban areas, especially in developing countries, will likely suffer from the impacts of changing climate. Her work also concludes that most cities are failing to (53) emissions of carbon dioxide and other greenhouse (54) . These gases are known to affect the atmosphere. "Climate change is a deeply local issue and poses profound threats to the growing cities of the world," says Romero Lankao. "But too few cities are developing effective strategies to (55) their residents. " Cities are (56) sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao's findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term (57) . The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential (58) associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat (59) paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. For example, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may (60) basic facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing (61) access to reliable drinking water, roads and basic services. Local governments, (62) , should take measures to protect their residents. Unfortunately, they tend to move towards rhetoric (63) meaningful responses. Romero Lankao writes, "They don't impose construction standards that could reduce heating and air conditioning needs. They don't emphasize mass transit and reduce (64) use. In fact, many local governments are taking a hands-off approach." Thus, she urges them to change their (65) policies and to take strong steps to prevent the harmful effects of climate change on cities.

单选题A Sunshade for the Planet Even with the best will in the world, reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties (不确定) in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time, resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented (执行) soon enough. Fortunately, if the worst comes to the worst, scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now, that is. A growing number of researchers are taking a fresh look at large-scale "geoengineering" projects that might be used to counteract (抵消) global warming. "I use the analogy of methadone," says Stephen Schneider, a climate researcher at Stanford University in California who was among the first to draw attention to global warming. "If you have a heroin addict,the correct treatment is hospitalization,and a long reha B. But if they absolutely refuse,methadone is better than heroin. " Basically the idea is to apply "sunscreen" to the whole planet. One astronomer has come up with a radical plan to cool Earth; launch trillions of feather-light discs into space,where they would form a vast cloud that would block the sun's rays. It's controversial,but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth's surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 per cent of the incident energy in the sun's rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere. That could be crucial, because even the most severe emissions-control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century, and that would last for at least a century more.

单选题Doubts and Debates over the Worth of MBA Bill Gates, the billionaire Microsoft chairman without a single earned university degree, is by his success raising new doubts about the worth of the business world's favorite academic title: the MBA ( Master of Business Administration). The MBA, a 20th-century product always has borne the mark of lowly commerce and greed (贪婪) on the tree-lined campuses ruled by purer disciplines such as philosophy and literature. But even with the recession apparently cutting into the hiring of business school graduates, about 79,000 people are expected to receive MBAs in 1993. This is nearly 16 times the number of business graduates in 1960, a testimony to the widespread assumption that the MBA is vital for young men and women who want to run companies some day. "If you are going into the corporate world it is still a disadvantage not to have one," said Donald Morrison, professor of marketing and management science. "But in the last five years or so, when someone says, ' Should I attempt to get an MBA,' the answer a lot more is: It depends. " The success of Bill Gates and other non-MBAs, such as the late Sam Walton of Wal-Mart Stores Inc. has helped inspire self-conscious debates on business school campuses over the worth of a business degree and whether management skills can be taught. The Harvard Business Review printed a lively, fictional exchange of letters to dramatize complaints about business degree holders. The article called MBA hires "extremely disappointing" and said "MBAs wants to move up too fast, they don't understand politics and people, and they aren't able to function as part of a team until their third year. But by then, they're out looking for other jobs. " The problem, most participants in the debate acknowledge, is that the MBA has acquired an aura (光环) of future riches and power for beyond its actual importance and usefulness. Enrollment in business schools exploded in the 1970s and 1980s and created the assumption that no one who pursued a business career could do with out one. The growth was fueled by a backlash (反冲) against the anti-business values of the 1960s and by the women's movement. Business people who have hired or worked with MBAs say those with the degrees often know how to analyze systems but are not so skillful at motivating people. "They don't get a lot of grounding in the people side of the business," said James Shaffer, vice president and principal of the Towers Perrin management consulting firm.

单选题Mad Scientist Stereotype Outdated Do people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed? The Institute of Physics set out to find out whether the stereotype of a physics "boffin" (科学家) still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong. The majority of people picked a white male of around 60, wearing glasses and with a white beard. While this stereotype may have been the image of all average physicist fifty years ago, the reality is now very different since 1960 the number of young women entering physics has doubled and the average age of a physicist is now 31. The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting by blackboards full of equations (等式) or working with fizzing (嘶嘶响) test tubes. These stereotypes are really damaging to society. Very good school children are put off studying science because they don"t see people like themselves on television or in magazines doing science. They simply don"t relate to the media"s image of the mad scientist. This is one reason why fewer young people are choosing to do science at university. If we want to encourage more young people to study science subjects, we need to change this image of the scientist and make science careers more attractive. But we must also develop children"s interest in science. In an attempt to change this negative image, an increasing number of science festivals are being organized. Thousands of people from secondary schools are also encouraged to take part in the international wide science competitions of which the most popular are the national Science Olympiads. Winning national teams then get the opportunity to take part in the International Science Olympiads which are held in a different country every year. These events are all interesting for the young people who take part but they only involve a small proportion of students who are already interested in science. It seems that there is a long way to go before science becomes attractive as subjects like computer studies or fashion and design.

单选题阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 On British Newspapers Besides the daily newspapers, there are a number of Sunday newspapers in Britain. Manyof them are connected with the "dailies", though not run by the same editor and his members.The Sunday papers are larger than the daily papers and usually contain more articles concernedwith comment (评论) and general information rather than news. The national daily and Sunday papers have the largest circulation(发行) in the world. Of the Sunday papers, the Observer and the Sunday Times are the best known. It is a regrettable fact that the number of magazines of a literary or political nature hasdropped down since the war. This has probably been caused by the everwider use of radio andtelevision. The most successful magazines are those published for women. Their covers aredesigned to catch the eye, and they certainly succeed in doing so! They offer their readers articles on cookery (烹饪法), fashion, needlework, and many other matters of women interest.They also provide advice to those in love, and adventures with handsome heroes. Somewomen's magazines also include serious articles of more general interest. The visitor who looks at the magazines displayed in a large bookstall (书摊) which may befound in an important railway station wiIl notice that there is a wide variety of technical or semitechnical(半专业的) books and magazines. There are magazines for the motorist, the farmer, the gardener, the nurse, and many others. There are many local and regional newspapers. It is common in Britain for a news agent(报刊经售人) to deliver (投递) the morning papers to his customers for a small extra payment, this service is usually performed by boys and girls who want to earn some pocketmoney.

单选题Arctic Melt Earth's North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low. Normally, ice builds in Arctic waters around the North Pole each winter and shrinks during the summer. But for many years, the amount of ice left by the end of summer has been declining. Since 1979, each decade has seen an 11.4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner. Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That's 38 percent less area than the average cover at that time of year. And it's a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has scientists concerned. There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water. Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃ warmer than average and 1.5℃ warmer than the previous record high. With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer measured just 50 centimeters by season's end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research and Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover.
