Evolution of SleepSleep is very ancient. In the electroencephalographic sense we share it with all the primates andalmost all the other mammals and birds: it may extend back as far as the reptilethere is some evidence that the two types of sleep, dreaming and dreamless, depend on thelife-style of the animal, and that predators are statistically much more likely to dream than prey,which are in turn much more likely to expenence dreamless sleep. In dream sleep, the animal ispowerfully immobilized and remarkably unresponsive to external stimuli.Dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears toa sound when apparently fast asleep. The fact that deep dream sleep is rare among prey today seemsclearly to be a product of natural selection, and it makes sense that today, when sleep is highly e-volved, the stupid animals are less frequently immobilized by deep sleep than the smart ones. Butwhy should they sleep deeply at all?why should a state of such deep immobilization ever have evolved? Perhaps one useful hint a-bout the original function of sleep is to be found in the fact that dolphins and whales and aquaticmammals in general seem to sleep very little. There is, by and large, no place to hide in the ocean.Could it be’that, rather than increasing an animal’s vulnerability, the function of sleep is to de-3-Crease it? Wilse W.e University of Florida and Ray Meddis of London University have sug-gested this to be the case. It is conceivable that animals who are too stupid to be quiet on their ownFor’ predrrirn/ais an;1ng tioro.ntbly at least partly true.A 16 Almost all the mammals and birds do sleep.

Natural Gas1 Natural gas is produced from reservoirs deep beneath the earth’s surface. It is a fossil fuel (矿物质燃料) , meaning that it is derived from organic material buried in the earth millions of years ago. The main component of natural gas is methane (甲烷).2 The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure (基础设施) has been installed to deliver it conveniently and economically to millions of residential, commercial and industrial customers worldwide. Today, natural gas service is available in all 50 states in the U. S. , and is the leading energy choice for fueling American homes and industries. More than 65 million American homes use natural gas. In fact, natural gas is the most economical source for home energy needs, costing one-third as much as electricity. In addition to heating homes, much of the gas used in the United States is used as a raw material to manufacture a wide variety of products, from paint, to fibers for clothing, to plastics for healthcare, computing and furnishings.. Natural gas is also used in a significant number of new electricity-generating power plants.3 Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide (二氧化碳)and water vapor-the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted (燃锣雹) ,making natural gas the cleanest burning fossil fuel of all.4 The United States consumes about one-third of the world’s natural gas output, making it the largest gas-consuming region in the world. The U. S. Department of Energy’s Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025.5 There are huge reserves of natural gas beneath the earth’s surface. The largest reserves of natural gas can be found in Russia, West and North Africa and the Middle East．LNG（液化天然气）has been produced domestically and imported in the United States for more than four decades. Today, the leading importers of LNG are Japan, Korea, France and Spain.A Popularity and use of natural gasB Natural gas reserves and supplyC Natural gas pricesD Clean fuel of choiceE Disadvantages of natural gasF Natural gas consumption23 Paragraph 2____A____24 Paragraph 3____D____25 Paragraph 4____F____26 Paragraph 5____B____27 Natural gas is stored deep__B____28 Natural gas is recognized as the most economical energy source___F___ 29 When manufacturing many products, people commonly use natural gas___E___ 30 It is estimated that by 2025 that natural gas demand in the United States will increase__C____ A over the past 50 yearsB beneath the earth surfaceC by more than 50 percentD for more than four decadesE as a raw materialF for home energy needs第4部分 阅读理解（第31~35题，每题3分，共45分）下面有3篇短文，每篇短文后有5道题。
请根据短文内容，为每题确定1个最佳选项第一篇 I'll Be Bach Composer David Cope is the inventor of a computerprogram that writes original works of classical music. It took Cope 30 years todevelop the software. Now most people can’t tell the difference between musicby the famous German composer J. S. Bach (1685-1750) and the Bach-likecompositions from Cope’s computer. It all started in 1980 in the United States, whenCope was trying to write an opera. He was having trouble thinking of newmelodies, so he wrote a computer program to create the melodies. At first thismusic was not easy to listen to. What did Cope do? He began to rethink howhuman beings compose music. He realized that composers，brains work like big databases.First, they take in all the music that they have ever heard. Then they take outthe music that they dislike. Finally, they make new music from what is left.According to Cope, only the great composers are able to create the databaseaccurately, remember it, and form new musical patterns from it. Cope built a huge database of existing music. He beganwith hundreds of works by Bach. The software analyzed the data：it broke it down into smallerpieces and looked for patterns. It then combined the pieces into new patterns.Before long, the program could compose short Bach-like works. They weren’t good,but it was a start.Cope knew he had more work to do-he had a wholeopera to write. He continued to improve the software. Soon it could analyzemore complex music. He also added many other composers, including his own work,to the database. A few years later，Cope’s computer program, called “Emmy”，was ready to help him with his opera. The process required a lot ofcollaboration between the composer and Emmy. Cope listened to the computer’smusical ideas and used the ones that he liked. With Emmy, the opera took onlytwo weeks to finish. It was called Cradle Falling, and it was a great success!Cope received some of the best reviews of his career, but no one knew exactlyhow he had composed the work. Since that first opera, Emmy has written thousandsof compositions. Cope still gives Emmy feedback on what he likes and doesn’tlike of her music, but she is doing most of the hard work of composing thesedays!31 The music composed by David cope is about ______. A. Classical music B. pop music C. drama D. country music32 By developing a computer software，David cope aimed ______. A. to be like Bach B. to study Bach C. to write an opera D. to create a musical database33 What did cope realize about a great composer’s brain? A. It forms new musical patterns allby itself B. It writes a computer program C. It can recognize any music patterns D. It creates an accurate database34 Who is Emmy? A. a database B. a computer softwareC. a composer who helped David D. an opera35 We can infer from the passage that ______. A. David Cope is a computerprogrammer. B. David Cope loves music. C. Bach’s music helped him a lot. D. Emmy did much more work than a composer第二篇： Explorer of the Extreme DeepOceans cover more than two-thirds of our planet. Yet, just a small ~raction of the underwater world has been explored. Now, Scientists at the Woods Hole Oceanographic Institution ( WHOI) in Massachusetts are building an underwater vehicle hat will carry explorers as deep as 6,500 meters (21,320 feet). The new machine,known as a manned submersible or human-operated vehicle (HOV) ,will replace another one named Alvin which has an amazing record of discovery,playing a key role in various important and famous undersea expeditions. Alvin has been operating for 40 years but can go down only 4,500 meters (14,784 feet). It’s about time for an upgrade,WHOI researchers say.Alvin was launched in 1964. Since then,Alvin has worked between 200 and 250 days a year,says Daniel Fornari,a manne geologist and director of the Deep Ocean Exploration Institute at WHOI. During its lifetime,Alvin has carried some 12,000 people on a total of more than 3,000 dives. A newer, better versions of Alvin is bound to reveal even more surprises about a world that is still full of mysteries, Fornan says. It might also make the job of exploration a little easier. “We take so much for granted on land. “ Fornari says. “We can walk around and see with our eyes how big things are. We can see colors,special arrangements. “Size-wise,the new HOV will be similar to Alvin.It’ll be about 37 feet long. The setting area inside will be a small sphere,about 8 feet wide,like Alvin. It’ll carry a pilot and two passengers. It will be just as maneuverable. In most other ways,it will give passengers more opportunities to enjoy the view, for one thing. Alvin has only three windows,the new vehicle will have five,with more overlap so that the passengers and the pilot can see the same thing.Alvin can go up and down at a rate of 30 meters every second,and its maximum speed is 2 knots (about 2.3 miles per hour) ,while the new vehicle will be able to ascend and descend at 44 meters per second.It’ll reach speeds of 3 knots,or 3.5 miles per hour.36 What is Alvin?A. A research institute. B. A transporting vehicle. C. A submersible. D. A scientist.37 Which of the following statements is NOT a fact about Alvin?A. It can carry explorers as deep as 6,500 meters. B. It has played a key role in various important undersea expeditions C. It was launched in the sixties of the twentieth century. D. It has been used for more than 40 years.38 “…a world that is still full of mysteries" refers to ______.A. the earth B. out space C. the ocean D. Mars39 In what aspects are the new HOV and Alvin similar?A. Size． B. Speed. C. Shape. D. Both A and C．40 In what aspects are the new HOV and Alvin different?A. Offering better views. B. Speed. C. Size. D. Both A and B．第三篇 Driven to DistractionJoe Coyne slides into the driver’s seat, starts up the car and heads to town. The empty stretch of interstate gives way to urban congestion, and Coyne hits the brakes as a pedestrian suddenly crosses the street in front of him.But even if he hadn’t stopped in time, the woman would have been safe. She isn’t real. Neither is the town. And Coyne isn’t really driving. Coyne is demonstrating a computerized driving simulator that is helping researchers at Old Dominion University(ODU) examine how in-vehicle guidance systems affect the person behind the wheel4.The researchers want to know if such systems, which give audible or written directions, are too distracting – or whether any distractions are offset5 by the benefits drivers get from having help finding their way in unfamiliar locations.We’re looking at the performance and mental workload of drivers,” said Caryl Baldwin, the assistant psychology professor leading the research, which involves measuring drivers’ reaction time and brain activity as they respond to auditory and visual cues.The researchers just completed a study of the mental workload involved in driving through different kinds of environments and heavy vs. light traffic. Preliminary results show that as people “get into more challenging driving situations, they don’t have any extra mental energy to respond to something else in the environment,” Baldwin said.But the tradeoffs could be worth it, she said. The next step is to test different ways of giving drivers navigational information and how those methods change the drivers’ mental workload.Is it best if they see a picture…that shows their position, a map kind of display?” Baldwin said. “Is it best if they hear it?”Navigational systems now on the market give point-by-point directions that follow a prescribed route. “They’re very unforgiving,” Baldwin said. “If you miss a turn, they can almost seem to get angry.”That style of directions also can be frustrating for people who prefer more general instructions. But such broad directions can confuse drivers who prefer route directions, Baldwin said.Perhaps manufacturers should allow drivers to choose the style of directions they want, or modify systems to present some information in a way that makes sense10 for people who prefer the survey style, she said.Interestingly, other research has shown that about 60 percent of men prefer the survey style, while 60 percent women prefer the route style, Baldwin said. This explains the classic little thing of why men don’t like to stop and ask for directions and women do, Baldwin added.41 Which statement is. True of the description in the first two paragraphs?A. If Coyne had stopped the car in time, he wouldn’t have hit the woman B. The woman would have been knocked over, if Coyne had followed the traffic regulations C. Coyne is not really driving so it is impossible for him to have hit the woman D. If the woman had not crossed the street suddenly, Coyne would not have hit her42 What do researchers want to find out, according to the third and fourth paragraphs?A. Whether or not audible or written directions are distracting B. How long it will take the driver to respond to auditory and visual stimuli. C. How the driver perform under certain mental workload. D. All of the above.43 What are the preliminary results given in the fifth paragraph?A. Drivers are afraid of getting into challenging driving situations. B. In challenging driving situations, drivers still have extra energy to handle other things. C. In challenging driving situations, drivers do not have any additional mental energy to deal with something else D. Drivers’ mental load remains unchanged under different situations.44 The sixth paragraph mainly state that the researchersA. are designing a visual navigational information system. B. are designing an audio navigational information system. C. are designing an audio-visual navigational information system. D. want to determine the best ways of giving navigational information system.45 What kind of directions do men and women prefer?A. Women prefer more general directions and men prefer route directions. B. Men prefer more general directions and women prefer route directions. C. Both men and women prefer general directions D. Both men and women prefer route directions.第五部分 补全短文（第46~50题，每题2分，共10分）下面的短文有5处空白，短文后有6个句子，其中5个取自短文，请根据短文内容将其分别放回原有位置，以恢复文章原貌。
The Joy of Living AloneMore and more Americans are living alone. Some live alone because of divorce or the death of a partner. (46)C According to a recent U.S. census（人口普查） ,25 Percent of all households in the U.S. are made up of just one person. This is a dramatic change from the extended families of just a couple of generations ago.The typical person living alone is neither old nor lonely. E (47) The majority of these people have chosen to live alone. They are responding to decreasing social pressure to get married and have a family.It’s now socially acceptable, even fashionable, to live alone. As people get better jobs and be-come financially independent, it becomes possible for them to maintain a one-person household. B (48) However, people who do get married are marrying at a later age and divorcing more oftenThe number one reason given by most people for living alone is that they simply enjoy doing what they want when they want to do it. “Living alone is a luxury,” says Nina Hagiwara, “Once you do it, you can’t ever go back to living with others. “David C. Debaca, agrees F (49)Children think that being grown up means being able to do exactly as they please. D (50) The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Americans are taking.A There's more pressure to get marr。
