二、阅读理解:【3道,总分:60分】
1. Not everyone in the world requires the same amount（量） of living space. The amount of space a person needs around him is a cultural(文化的) difference, not an economic(经济的) one. Knowing your own psychological(心理的) space needs is important because they strongly affect your choices, including, for example, the number of bedrooms in the home. If you were brought up in a two-child family and both you and your sister or brother had your own bedrooms, the chances are if you have two children or more, that you also will offer separate bedrooms for them. In America, for example, they train people to want to have their own rooms by giving them their own rooms when they are babies. This is very unusual in the world. In many other countries, the baby sleeps in the same bed with his parents or in bed near them. The space in the home also shows a lot about psychological space needs. Some families gather closer to each other and the size of their house has nothing to do with it. Others have separate little corners where family members go to be alone. Although it is true that psychological space needs are not decided by economic reasons, they sometimes have to be changed a little because of economic pressure（压力）. It is almost impossible, however, to completely change your psychological space needs. (满分:)
1).?The first sentence in Paragraph 1 “Not everyone in the world requires the same amount of space” means “( )”.
A. Not two people need exactly the same amount of living space
B. Living space requirements are not always the same
C. The world requires the same amount of living space
D. Nobody needs a required amount of living space
2).?Some families gather closer to each other at home than others because ( ).
A. they have limited living space
B. they are brought up in a large family
C. it satisfies（满足） their psychological space needs
D. the children in the family sleep in the same bed with their parents
3).?Which of the following is true according to the passage?
A. Americans are trained to live in the large rooms at birth.
B. Economic situation decides one's amount of space needs.
C. People in different countries demand(need) different psychological space.
D. Knowing your psychological space needs is important, as it has effect on your future.
4).?The best title for this passage is ( ).
A. American Way of Living
B. Psychological Space
C. Space Needs in Different Countries
D. Psychological Space and Economic Pressure
5).?According to the author, it is ( ) to change completely change people’s psychological space needs.
A. impossible
B. likely
C. probably
D. almost impossible
2. Why are so many people so afraid of failure? Quite simply, because we forget that failure is part of the human condition and every person has the right to fail. Most parents work hard at either preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards. A mother describes her child's hand-made table as “perfect” even though it doesn't stand still. Another way is to shift(转移) blame. If John fails science, his teacher is unfair or stupid. The trouble with failure-prevention devices(策略) is that they leave a child unequipped for life in the real world. The young need to learn that no one can be best at everything, no one can win all the time --- and that it's possible to enjoy a game even when they don't win. A child who's not invited to a birthday party feels terrible, of course. But parents should not offer a quick consolation(安慰) or say, “It doesn't matter.” because it does. The young should be allowed to experience disappointment and be helped to master it.Failure is never pleasurable. It hurts grown-ups and children alike. But it can make a positive(积极的) contribution to your life once you learn to use it. Don't blame someone else. Ask yourself what you did wrong, how you can improve. If someone else can help, don't be shy about asking. Success is not nearly as good a teacher as failure. You can learn from a bad party how to give a good one. Even a failure that seems definitive can prompt fresh thinking, a change of direction. After 12 years old of studying ballet, a friend of mine interviewed for a professional company. She was turned down. In such cases, the way to failure is to use failure is to take stock(鉴定) bravely asking “What else can I do?”. My friend put away her shoes and moved into a dance treatment center, a field where she's both able and useful. Failure frees one to take risks because there's less to lose. Often there is recovery(恢复) of energy—a way to find new possibilities. (满分:)
1).?The second paragraph mainly tells us .
A. how parents encouraged their children when they had failed
B. how most parents responded to their children's failure
C. how to shift blame
D. how to properly prevent children's failure.
2).?According to the text, what should a child know in the real world?
A. He should be equipped for life.
B. No one can be best at all the time at everything.
C. No parents should offer quick consolations.
D. He can get pleasure from failure as well as success.
3).?The underlined word “prompt” in the last paragraph can be best replaced by .
A. improve
B. prevent
C. continue
D. cause
4).?Which of the following is not true? Failure is .
A. part of human condition.
B. not always a bad thing
C. never pleasurable
D. destroying all our life
5).?The writer mainly wants to tell us .
A. failure is never pleasurable
B. don't blame someone else
C. failure can affect one's life greatly once he learns to use it
D. failure frees everyone to take risks
3. Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat(闲谈) with friends—you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you—loudly enough and clearly enough but without trying to shout or appearing to force yourself. Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease(轻松) but the situation is somewhat(一点儿) different from that of an ordinary conversation. You must take special care that you can be heard. (满分:)
1).?When you speak to the class, you should speak ————
A. as loudly as possible
B. in a low voice
C. loudly
D. forcefully
2).?Usually, when you speak to the class, the class is ————

二、阅读理解:【3道,总分:60分】
1. One of the things I always believe is that no matter how bad something is, you can take something positive out of it. The one thing I wasn't sure of that was on September 11. I usually wake up at 6:30 or 7:00 in the morning. That day, I happened to wake up earlier. I turned on the TV and I saw that a plane had crashed into the North Tower of the World Trade Center. My first reaction was that it was a terrible accident. Then I saw another plane fly into the South Tower and I realized that I was witnessing(目击) an act of terrorism. My wife and I spent the day watching the terrible pictures over and over again. When I watched family members looking for their loved ones, the pain in their eyes was something I would never forget. I couldn't understand how something this terrible could have happened.It wasn't until a few weeks after September 11 that I began to see that perhaps some good did come from this tragedy（悲剧）. People seem different now, more understanding, more tolerant(宽容的). Things that seemed to be such a trouble before are no longer big things. Personally, I am more tolerant than I was. I realize life is too short, and too precious（珍贵的）to let myself get worried over small things. I've learned also that you can't take things for granted. Things change in the blink(眨眼) of an eye. People go to work and don't come back. One moment they're living and the next minute they're not. And no matter who you are, there is nothing you can do about it. We never know when our time here will be over, so we call need to make the most of every minute we have. You try to learn from what happened. You can't be used up by it. You can't live by it. All you can do is just live. (满分:)

2. In the late 1960's, many people in North America turned their attention to environmental problems, and new steelanglass skyscrapers were widely criticized. Ecologists pointed out that a forest of tall buildings in a city often overburdens public transportation and parking lots.Skyscrapers are also consumers and wasters of electric power. In one recent year, the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120,000 kilowatts—enough to supply the entire city of Albany, New York, for a day. Glass-walled skyscrapers can be especially wasteful. The heat loss(orgain)through a wall of half inch plate glass is more than ten times that through a typical brick wall filled with insulation(绝缘)board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glaze panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare(眩目的光)as well as heat gain. However, mirror walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.Skyscrapers put a strain on a city's sanitation facilities(卫生设备), too. If fully occupied, the two World Trade Center towers in New York City would alone produce 2.25 million gallons of wastes each year—as much a city the size of Stanford, Connecticut, which has a population of more than 109,000. Skyscrapers also affect television reception, block bird flyways and air traffic. In Boston in the late 1960's,some people even feared that shadows from skyscrapers would kill the grass on Boston Common.Still, people continue to build skyscrapers for all the reasons that they have always built them—personal pride and the desire of owners to have the largest possible amount of space to rent. (满分:)
1).?The main purpose of the passage is to——
A. compare skyscrapers with other modern structures
B. describe some architectural designs of skyscrapers
C. describe skyscrapers and their effect on the environment
D. encourage using bricks in the construction of skyscrapers
2).?According to the passage, what is one disadvantage of skyscrapers that have mirrored walls?
A. The surrounding air is heated.
B. Construction time is increased.
C. The windows must be cleaned daily.
D. Extra air conditioning equipment is needed.
3).?According to the passage, in the late 1960’s some residents of Boston were concerned with which aspect of skyscrapers?
A. The noise from their construction.
B. The high cost of renting an office.
C. The harmful effects on the city's grass.
D. The removal of trees from building sites.
4).?The author raises problems that would most concern which of the following groups?
A. Pilots
B. Electricians
C. Environmentalists
D. Construction workers
5).?The underlined word“ecologists” in paragraph one means————
A. experts on construction
B. experts on electric facilities
C. experts on the building materials
D. experts on protecting the environment
3. Every year more and more plants and animals disappear never to be seen again. Strangely, it is the most intelligent but most thoughtless animal that is causing most of the problems—man. Nature is very carefully balanced and if this balance is disturbed, animals can disappear alarmingly(令人担忧地) fast. Every day, thousands of species of animals draw closer to extinction. There are countless numbers of species which may become extinct before they are even discovered. In many lakes the fish are dying. Fishermen are worried because every year there are fewer fish and some lakes have no fish at all. Scientists are beginning to get worried too. What is killing the fish? The problem is acid rain. Acid rain is a kind of air pollution. It is caused by factories that burn coal or oil or gas. These factories send smoke high into the air. The wind often carries the smoke far from the factories. Some of the harmful substances in the smoke may come down with the rain hundreds of miles away. The rain in many places isn't natural and clean any more. It's full of acid chemicals. When it falls in lakes, it changes them too. The lakes become more acidic. Acid water is like vinegar or lemon juice. It hurts when it gets in your eyes. It also kills the plants and animals that usually live in lake water. That is why the fish are dying in lakes. But dead fish may be just the beginning of the problem. Scientists are finding other effects of acid rain. In some large areas trees are dying. Not just one tree here and there, but whole forests. At first scientists couldn't understand why. There were no bugs or diseases in these trees. The weather was not dry. But now they think that the rain was the cause. Acid rain is making the earth more acidic in these areas. Some kinds of trees cannot live in the soil that is very acidic. Now scientists are also beginning to study the effects of acid rain on larger animals. For example, they believe that some deer in Poland are less healthy because of acid rain. If deer are hurt by the rain, what about people? This is the question many people are beginning to ask. No one knows the answer yet. But it is an important question for us all. (满分:)
