Reading Comprehension Directions: There are three passages in this part. Each passage is followed by some questions. For each of them there are four choices marked A, B, C and D. You should decide on the best choice. (30 points) Passage 1When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are. People who are near-sighted can only see things that are very close to their eyes, Everything else seems blurry(=unclear). Many people who do a lot of work, such as writing, reading and sewing become near-sighted. Then people who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arms length. If they want to do much reading ,they must get glasses, too. Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some peoples eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them. Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object our of one eye; then look at the same object out of your other eye. You will find the objects relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.21. We should take good care of our eyes . A. only when we can see well B. only when we cannot see perfectly C. even if we can see well D. only when we realize how important our eyes are22. When things far away seem indistinct(模糊不清) , one is probably . A. near-sighted B. far-sighted C. astigmatic D. suffering from cataracts23. The underlined word suffer in the second paragraph probably means . A. experience B. imagine C. feel pain D. are affected with24. Having two eyes instead of one is particularly useful for . A. seeing at night B. seeing objects far away C. looking over a wide area D. judging distances25. People who suffer from astigmatism have . A. one eye bigger than the other B. eyes that are not exactly the right shape C. a difficulty that can be corrected by an operation D. an eye difficulty that cannot be corrected by glassesPassage 2In earliest times, men considered lightning to be one of the great mysteries (神秘的事物) of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡). The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning. Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second. Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day. The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.With lightning, it is better to be safe than sorry?26. People once thought lightning came from _.A. the sky B. the gods C. the earth D. nature27. According to the passage what do you think all buildings need?A. Metal fences. B. Electricity. C. lightning rods. D. Machines.28. Lightning can travel _.A. as quickly as water B. not so quickly as electricityC. at very low speed D. at very high speed29. Which of the following is NOT true?A. In the U.S about one person per day dies from lightning.B. The Empire State Building frequently gets hit by lightning.C. Swimming during a thunder storm is a good idea.D. A closed car is the best place to be during an electrical storm.30. Lightning is probably _ to man.A. useful B. kind C. useless D. friendlyPassage 3It must have been around nine Oclock when I drove back home from work because it was already dark. As I came near to the gates I turned off the headlamps of the car so as to prevent the beam(光荣) from swinging(摇摆)in through the window and waking Jack, who shared the house with me. But neednt have done so, I noticed that his light was still on, so he was awake anyway- unless he had fallen asleep while reading. I put the car away and went up the steps, Then I opened the door quietly and went to Jacks room. He was in bed awake but he didnt even turn towards me.“Whats up, Jack?” I said.“For Gods sake(看在上帝面上), dont make a noise,” he said.The way he spoke reminded me of someone in pain who is afraid to talk in case he does himself a serious injury(伤害).“Take your shoes off, Neville,” Jack said.I thought that he must be ill and that I had better humour (迁就)him to keep him happy, “Theres a snake here” he explained, “Its asleep between the sheets. I was lying on my back reading when I saw it. I knew that moving was out of the question. I couldnt have moved even if Id wanted to .” I realized that he was serious. “I was relying on you to call a doctor as soon as you came home.” Jack went on.“It hasnt bitten me yet but I darent do anything to upset it. It might wake up. Im sick of this,” he said,“ I took it for granted that you would have come home an hour ago.”There was no time to argue or apologize for being late. I looks at him as encouragingly as I could and went out to telephone the doctor.31. When he got home, Neville found that _?A. Jack had fallen asleep while reading B. Jack had been reading for some timeC. Jacks light was not turned off D. Jack was ready to answer the door32. The underlined phrase out of the question means _.A. impossible B. no problem C. no doubt D. without difficulty33. Which of the following statements is NOT true according to the passage? A.

According to the passage, Neville should have been home at _.A. 7p. m B. 8p. m C. 9p. m D. midnightPassage 4Overhead bridges are found in many parts of Beijing, especially in places where traffic is very heavy and crossing the road is dangerous.The purpose of these bridges is to enable pedestrians (行人) to cross roads safely. Overhead bridges are used to very much the same way as zebra crossings. They are more efficient (效率高的) although less convenient because people have to climb up a long flight of steps. This is inconvenient especially to older people. When pedestrians use an overhead bridge, they do not hold up traffic. However, when they cross a busy road using a zebra crossing, traffic is held up. This is why the government has built many overhead bridges to help pedestrians and to keep traffic moving at the same time.The government of Beijing has spent a large amount of money on building these bridges. For their own safety, pedestrians should be encouraged to use them instead of risking (冒危险) their lives by dashing across the road. Old people , however , may find it a little difficult climbing up and down the steps, but it is still much safer than walking across the road with all the danger of moving traffic.Overhead bridges serve a very useful purpose. Pedestrians, both old and young, should make it a habit to use them. This will prevent unnecessary accidents and loss of life.36. What is the advantage of overhead bridges mentioned in this passage? A. Taller trucks can pass under them.B. Pedestrians can climb up and have a view of the city.C. They are safer for pedestrians and can keep traffic moving at the same time.D. They are easier and more convenient for the pedestrians.37. Why were overhead bridges built in Beijing? A. Because they prevent traffic from being held up.B. Because they provide an easy way for the drivers to cross the road.C. Because they save money for the government.D. Because they save time for the pedestrians.38. Which of the following statements is true according to the passage? A. Overhead bridges are found in every part of Beijing.B. Overhead bridges are only found in the centre of Beijing.C. Overhead bridges are found in many parts of big cities in China.D. Overhead bridges are found in places where traffic is heavy.39. The underlined words a zebra crossing probably mean _.A. a safe place across a road for pedestrians to walk across the roadB. a wild animal from Africa that looks like a horse with broad dark brown and white stripes on its bodyC. a safe place across a road for zebras to walk across the roadD. a safe place across a road for children to play a game40. What is the writers attitude towards overhead bridges?A. It is inconvenient to older people to walk across the road.B. It is much safer for pedestrians though climbing up and down the steps may be a little difficult,C. An overhead bridge is more beautiful than a zebra crossing.D. To build overhead bridges is the business of the government.Passage 5The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image (形象) of unhappy teenagers locked in their room after endless family quarrels.An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past. “We were surprised by just how positive (肯定的) todays young people seem to be about their families,” said one number of the research team. “Theyre expected to be rebellious (叛逆的) and selfish but actually they have other things on their minds： they want a car and material goods, and they worry about whether school is serving them well. Theres more negotiation (商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They dont want to rock the boat (捣乱)。 ”So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me，” says 17-year-old Daniel Lazall. “I always tell the when Im going out clubbing. As long as they know what Im doing, theyre fine with me.” Susan Crome， who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as Id done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments (评论) , “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”41. What is the popular if the teenager today? A. They worry about school. B. They dislike living with their parents.C. They have to be locked in to avoid troubles. D. They quarrel a lot with other family members.42. The study shows that teenagers dont want to _. A. share family responsibility B. cause trouble in their familiesC. go boating with their family D. make family decisions43. Compared with parents of 30 years ago， todays parents _.A. go to clubs more often with their children B. are much stricter with their childrenC. care less about their childrens life D. give their children more freedom44. According to the writer， teenage rebellion _.A. may be a false belief B. is common nowadaysC. existed only in the 1960s D. resulted from changes in families45. What is the passage mainly about? A. Negotiation in family. B. Education in family.C. Harmony in family. D. Teenage trouble in family.Passage 6It was a winter morning, just a couple of weeks before Christmas 2005.
