The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. Sagan was standing on the edge of one of the tanks where several of these friendly, highly intelligent creatures were kept. Elvar had just swum up alongside him and had turned on his back. 　　The dolphin wanted Sagan to scratch his stomach again, as the astronomer had done twice before. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water and made a sound just like the word "more". The astonished astronomer went to the director of the institute and told him about the incident. “Oh, yes. That’s one of the words he knows,” the director said, showing no surprise at a11. 　　Dolphins have bigger brain in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and much further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphin than in humans. But can it be said that dolphins have a “language” in the real sense of the word? Scientists don’t agree on this. 　　A language is not just a collection of sounds, or even words. A language has a structure and what we call a grammar. The structure and grammar of a language help to give it meaning. For example, the two questions “Who loves Mary?” and “Who does Mary love?” mean very different things. If you stop to think about it, you will see that this difference doesn’t come from the words in the question but from the difference in structure. That is why the question “can dolphins speak?” Can’t be answered until we find out if dolphins not only make sounds, but also arrange them in a grammatical order which affects their meaning. 　　16. The astronomer was not interested in the way dolphins communicate with each other. 　　A.Right 　　B.Wrong 　　C.Not mentioned 　　17. The dolphin leapt up into the air because Sagan was too near the water. 　　A.Right 　　B.Wrong 　　C.Not mentioned 　　18 Parts of the dolphin’s brain are particularly well developed to handle different kinds of sound. 　　A.Right 　　B.Wrong 　　C.Not mentioned 　　19. Dolphins are the most useful animals to humans. 　　A Right 　　B.Wrong 　　C.Not mentioned 　　20. Dolphins travel faster in water than any other animals. 　　A.Right 　　B.Wrong 　　C.Not mentioned 　　21. Some scientists believe that dolphins have a language of their own. 　　A.Right 　　B.Wrong 　　C.Not mentioned 　　22. Sounds can be called a language only when they have a structure and a grammar. 　　A.Right 　　B.Wrong 　　C.Not mentioned第3部分：概括大意与完成句子(第23～30题，每题1分，共8分) 　　下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第1～4段每段1选择个标题;(2)第27～30题要求从所给的6个选项中为每个句子确定1个选项。 　　The Weight Experiment 　　Nicola Waiters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a "caioriineier" (热量测试室) is one way to find out. 　　1. The signs above the two rooms read simply “Chamber One” and “Chamber Two”. These are the calorimeters: 4m by 2m white-walled rooms where human volunteers are locked up in the name of science. Outside these rooms another sign reads, "Please do not enter work in progress" and in front of the rooms advanced machinery registers (记录) every move the volunteers make. Each day, meals measured to the last gram axe passed through a hole in the wall of the calorimeter to the resident volunteer. 　　2. Nicola Walters is one of the twenty volunteers who, over the past eight months, have spent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness program. 　　A.self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert (广告) for volunteers at her gym and as she is interested in the whole area of diet and exercise, she thought she would help out. 　　3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence (次序) was repeated four times over six weeks. She arrived at the calorimeter at 8:30 a.m. on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, bet daily exercise routine timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were taken for analysis. 　　4. The scientists help volunteers impose (确立) a kind of order on the long days they face in the room. “The first time, I only took one video and a book, but It was OK because I watched TV the rest of the time,” says Nicola. And twice a day she used the exercise bike. She pedaled (踩踏板) for half an hour, watched by researchers to make sure she didn't go too fast. 　　5. It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full, Believing that they may now know what encourages people to overeat, the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sessions. 　　23. Paragraph 1___ 　　24. Paragraph 2___ 　　25. Paragraph 3___ 　　26. Paragraph 4___ 　　A.What does the calorimeter look like inside? 　　B.What program was designed for the experiments? 　　C.What is a calorimeter? 　　D.What is the first impression? 　　E.How do the volunteers kill the time? 　　F.Why did Nicola join in the experiments? 　　27. The machinery outside the calorimeters records everything_______. 　　28. Nicola Walters had time for the experiments 　　29. Volunteers have to get prepared for the time in the calorimeter 　　30. The experiments show that high-fat diets_______ 　　A.the volunteers do 　　B.because she does not have a weight problem 　　C.because the life there can be very boring 　　D.make people overeat 　　E.because she was her own boss 　　F.after passing a high-protein test　　第4部分：阅读理解(第31～45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个选项。 　　第一篇 　　Recycling Around the World 　　Recycling is one of the best environmental success stories of the late 20th century. But we could do more. People must not see recycling as fashionable, but essential. 　　The Japanese are very good at recycling because they live in a crowded country. They do not have much space. They do not want to share their limited space with rubbish. But even so, Tokyo area alone is estimated to have three million tons of leftover rubbish at present. 　　In 1996, the United States recycled and composted (制成肥料)57 million tons of waste (27% of the nation's solid waste). This is 57 million tons of waste which did not go into landfills and incinerators (焚化炉). In doing this,7,000 rubbish collection programmes and recycling centers helped the authorities. 　　In Rockford, a city in Illinois, US, its officials choose one house each week and check its garbage (废物). If the garbage does not contain any newspapers or aluminium (铝) cans, then the resident of the house gets a prize of at least $1,000. 　　In Japan, certain cities give children weekly supplies of tissue paper and toilet paper in exchange for a weekly collection of newspapers. 　　In one year Britain recycles: 　　1 out of every 3 newspapers. 　　1 out of every 4 glass bottles and jars (罐子). 　　1 out of every 4 items of clothing. 　　1 out of every 3 aluminium drink cans. 　　In 1999, Hong Kong transported 1.3 million tons of waste to mainland China for recycling. Around 535,000 tons of waste were recycled in Hong Kong itself. 　　Over half the things we throw away could be recycled. That means we could recycle 10 times as much as we do now. 　　However, recycling needs a lot of organization and special equipment. Also, there is not much use for some recycled material. 　　31. Which of the following is NOT true of the Japanese? 　　A.They live in a crowded country. 　　B.They have recycled all their waste. 　　C.They are very good at recycling. 　　D.They have to share their limited space with rubbish 　　32. How much waste did the US recycle in 1996? 　　A.1.3 million tons. 　　B.27 million tons. 　　C.57 million tons. 　　D.53 million tons. 　　33. Where can people get a big prize for contributing to recycling? 　　A.Rockford. 　　B.Tokyo. 　　C.Hong Kong. 　　D.London. 　　34. In Japan, the newspapers collected by children 　　A.are given to poor people. 　　B.are used as reading materials. 　　C.are used as prizes. 　　D.are recycled. 　　35. Which of the following is NOT true of Britain? 　　A.It recycles 1 out of every 3 newspapers each year. 　　B.It recycles 1 out of every 4 glass bottles and jars each year 　　C.It recycles 1 out of every 3 aluminium cans each year. 　　D.It recycles 1 out of every 4 items of clothing each year.　　Superconductor Ceramic(陶瓷) 　　An underground revolution begins this winter, with the flip(轻击)of a switch,30,000 homes in one part of Detroit will soon become the first in the country to receive electricity transmitted by ice-cold high performance cables. Other American cities are expected to follow Detroit’s example in the years ahead, which could conserve enormous amounts of power. 　　The new electrical cables at the Frisbie power station in Detroit are revolutionary because they are made of superconductors. A superconductor is a material that transmits-electricity with little or no resistance. Resistance is the degree to which a substance resists electric current. All common electrical conductors have a certain amount of electrical resistance. They convert at least some of the electrical energy passing through them into waste heat. Superconductors don' t No one understands how superconductivity works. It just does. 　　Making superconductors isn't easy. A superconductor material has to be cooled to an extremely low temperature to lose its resistance. The first superconductors, made more than 50 years ago, had to be cooled to-263 degrees Celsius before they lost their resistance. Newer superconducting materials lose their resistance at-143 degrees Celsius. 　　The superconductors cable installed at the Frisbie station is made of a ceramic material that contains copper, oxygen, bismuth(铋), strontium(锶),and calcium (钙). A ceramic is a hard. strong compound made from clay or minerals. The superconducting ceramic has been fashioned into a tape that is wrapped lengthwise around a long tube filled with liquid nitrogen. Liquid nitrogen is superconductors and lowers the temperature of the ceramic tape to the point where it conveys electricity with zero resistance. 　　The United States loses an enormous amount of electricity each year to resistance.’ Because cooled superconductors have no resistance, they waste much less power. Other cities are watching the Frisbie experiment in the hope that they might switch to superconducting cable and conserve power, too. 　　36. What is the benefit of the revolution mentioned in the first paragraph? 　　A.With a flip of swish, electricity can be transmitted. 　　B.Other American cities can benefit from the high performance cables. 　　C.Great amounts of power can be conserved. 　　D.Detroit will first receive electricity transmitted by the new electrical cables 　　37. Compared to common electrical conductors, superconductors 　　A.have little or no electrical resistance. 　　B.Can be used for along time. 　　C.are not energy-efficient. 　　D.can be made easily. 　　38. At what temperature does the superconducting ceramic lose its resistance? 　　A.-143 degree Celsius. 　　B.-263 degree Celsius. 　　C.As long as it is ice-cold. 　　D.Absolute zero. 　　39. What element enables the ceramic tape to lower its temperature? 　　A.Copper. 　　B.Liquid nitrogen.. 　　C.Clay. 　　D.Calcium. 　　40. According to the last paragraph, which of the following statements is NOTtrue? 　　A.Other cities hope they Can also conserve power. 　　B.Other cities hope they Can use superconducting cables soon. 　　C.Superconductors waste less power because of their low resistance. 　　D.The Fribie experiment is not successful.　Sunspots 　　It's not surprising that sunspots (太阳黑子) were observed by ancient astronomers (天文学家). The largest sunspots on the sun can be seen without a telescope. It was not until the invention of the telescope (望远镜) in the early 17th century, however, that systematic studies of sunspots could be undertaken. The great astronomer Galileo was among the first to make telescopic observations of sunspots. 　　Sunspots are regions of extremely strong magnetic fields (磁场) found on the sun's surface. A sunspot has a dark central core known as the umbra. The umbra is surrounded by a dark ring called the penumbra. where the magnetic field spreads outward. Sunspots appear dark because they are giving off less radiation. They are cooler than the rest of the sun's surface. 　　Sunspots are frequently observed in pairs or in paired groups. The members of a spot pair are identified as the leading spot and the following spot. They are identified by their position In the pair In terms of the direction in which the sun rotates (旋转). 　　The number of sunspots at any one time varies. A large spot group may consist of as many as 10 groups and 300 spots across the sun. The number of spots changes in a fairly regular pattern called the sunspot cycle. The largest number occurs about every 11 years. At sunspot minimum, there are at most just a few small spots. 　　The average lifetime of an individual spot group is roughly one solar rotation, which is about 25 days. The most persistent large spots, however, can survive for two to three months. 　　41. Careful observations and systematic studies of sunspots 　　A.were made by ancient astronomers. 　　B.started in the early 17th century. 　　C.were made by Galileo only. 　　D.could be made without a telescope. 　　42. Sunspots are cooler than the rest of the sun's surface because 　　A.they produce less energy. 　　B.they are buried in the sun. 　　C.they are far away from magnetic fields. 　　D.they are close to magnetic fields. 　　43. The leading spot and the following spot are the names of 　　A.two large sunspots. 　　B.a large spot and a small spot. 　　C.the two spots in a spot pair. 　　D.the central core and the ring around it. 　　44. If an intense sunspot activity had occurred in 1857, the next one would have been in 　　A.1858. 　　B.1862. 　　C.1865. 　　D.1868. 　　45. In the last paragraph the word "persistent" means 　　A.important. 　　B.effective. 　　C.enduring. 　　D.visible.　第5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。 　　How Did She Conquer the Americans? 　　African-American talk show queen Oprah Winfrey is the world's most powerful celebrity, according to Forbes magazine.______ (46) 　　Winfrey, 51, draws 30 million viewers weekly in the United States.
