单选题Eiffel Is an Eyeful Some 300 meters up, near the Eiffel Tower's wind-whipped summit the world comes to scribble. Japanese, Brazilians, Americans they graffiti their names, loves and politics on the cold iron -- transforming the most French of monuments into symbol of a world on the move. With Paris laid out in miniature below, it seems strange that visitors would rather waste time marking their presence than admire the view. But the graffiti also raises a question: Why, nearly 114 years after it was completed, and decades after it ceased to be the world's tallest structure, is la Tour Eiffel still so popular? The reasons are as complex as the iron work that graces a structure some 90 stories high. But part of the answer is, no doubt, its agelessness. Regularly maintained, it should never rust away. Graffiti is regularly painted over, but the tower lives on. "Eiffel represents Paris and Paris is France. It Is very symbolic," says Hugues Richard, a 31-year-old Frenchman who holds the record for cycling up to the tower's second floor -- 747 steps in 19 minutes and 4 seconds, without touching the floor with his feet. "It's iron lady, it inspires us," he says. But to what? After all, the tower doesn't have a purpose. It ceased to be the world's tallest in 1930 when the Chrysler Building went up in New York. Yes, television and radio signals are beamed from the top, and Gustave Eiffel, a frenetic builder who died on December 27, aged 91, used its height for conducting research into weather, aerodynamics and radio communication. But in essence the tower inspires simply by being there -- a blank canvas for visitors to make of it what they will. To the technically minded, it's an engineering triumph. For lovers, it's romantic. "The tower will outlast all of us, and by a long way," says Isabelle Esnous, whose company manages Eiffel Tower.

单选题{{B}}第二篇{{/B}} {{B}}Cousteau Remembered{{/B}} Jacques-Ives Coustean died in Paris on 26 June, 1997 at the age of 87. His influence is great. Scientists respected his creative engineering; engineers praised his science. Coustean, who claimed to be neither scientist nor engineer, contributed significantly to both disciplines — and to many more. Throughout his adventure-filled life, Coustean challenged definitions. Yes, he was a captain in the French Navy, and early on, a filmmaker and natural storyteller. Later, he became a famous ocean explorer, designer of underwater equipment, expedition leader, author, speaker, businessman, environmentalist, teacher and leader of an influential organization (the Cousteau Society). All who care about the sea — and even those who don't think much about the ocean one way or another — owe Coustean a tremendous debt. The knowledge gained as a consequence of his direct contributions, and the strong others, have transformed the way the world thinks about the sea. His stories, of encounters with sharks and other fish inspired many to go see themselves. Coustean pioneered ventures in underwater living in the 1960's: sub-sea labs where scientists submerged for days or weeks — the underwater labs similar to skylab or the space station. His films and television programmes won two Academy Rewards, three Emnies, and the hearts and minds of viewers worldwide for decades. Showered with honours, Cousteau remarked recently that he thought his most important accomplishment was to make people aware of— and care about — the ocean. Thanks to him, we grew concerned about our growing population and the consequences of over fishing and ocean pollution that threaten the health of the sea, and we were inspired to do something to improve the way things are done. We shared the sad feeling with Cousteau when Simone, his wife and partner for many years, died and when his son Phillippe was killed in a plane crash. We shared his joy when Jean Michael, his eldest son, became an explorer and a spokesman for the sea in his own right. We were happy for Coustean when he began a new family with his second wife, Fracine. And now that his voice of the ocean is silenced, we feel very sad.

单选题Storms Sink Ships Rescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing or feared dead. The two ferries sank in different rivers near the capital city of Dhaka as strong winds and rain hit the South Asian country. The government has since banned all ferries and other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made for just 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry or how many of them survived." Ferries in Bangladesh don"t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed and 400 injured by lightning strikes, falling houses and trees and the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures, too many passengers in boats and not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation"s waterways every year. And many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.

单选题 Genetically Modified Foods If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, healthy, safety and ethical questions. Particularly in countries with long grain traditions-and vocal green lobbies--the idea seems against nature. In fact, genetically modified foods are already very much a part of out lives. A third of the corn and more than half the soybeans and cotton grown in the U.S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U.S. this year. The genetic genie (妖怪) is out of the bottle. Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations, the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The U.N. estimates that nearly 800 million people around the world are undernourished. The effects are devastating. About 400 million women of child-bearing age are iron deficient, which means their babies are exposed to various birth defects. As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness. How can biotech help? Biotechnologists have developed genetically modified rice that is fortified with beta-carotene-which the body converts into vitamin A and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to pests, drought, poor soil and crop viruses, bacteria or fungi.

单选题阅读下面这篇短文，短文后列出了7个句子，请根据短文的内容对每个句子做出判断。 {{B}} Mad Scientist Stereotype Outdated{{/B}} 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 an 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 nationwide 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"Liquefaction" Key to Much of Japanese Earthquake Damage The massive subduction zone earthquake in Japan caused a significant level of soil "liquefaction" that has surprised researchers with its widespread severity, a new analysis 1 "We"ve seen localized examples of soil liquefaction as extreme as this before, but the distance and 2 of damage in Japan were 3 severe," said Scott Ashford, a professor of geotechnical engineering at Oregon State University. "Entire structures were tilted and sinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines, crippling the utilities and infrastructure these communities need to function. We saw some places that sank as 4 as four feet." Some degree of soil liquefaction is common in almost any major earthquake. It"s a phenomenon in which soils soaked with water, 5 recent sediments or sand, can lose much of their 6 and flow during an earthquake. This can allow structures to shift or sink or collapse. But most earthquakes are much shorter than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to 7 the extent of liquefaction damage possibly occurring in situations such as this. "With such a long-lasting earthquake, we saw 8 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on recently filled ground, are much more 9 " The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil phenomenon and better prepare 10 it in the future. Ashford said it was critical for the team to collect the information 1 , before damage was removed in the recovery efforts. "There"s no doubt that we"ll learn things from what happened in Japan that will help us to reduce risks in other similar 12 ," Ashford said. "Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns." Ashford pointed out that northern California have younger soils vulnerable to liquefaction—on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic terms, may be those 13 with in the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities. Anything near a river and old flood plains is a suspect, and the Oregon Department of Transportation has already concluded that 1, 100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 14 collapse. Japan has 15 tremendous losses in the March 11 earthquake, but Japanese construction standards helped prevent many buildings from collapse—even as they tilted and sank into the grourd.
