    The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.
    To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威胁) our health, our happiness and our life.
    Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工业) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.
    Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.
    Our increasing population is part of the problem. More people, more waste.
    Where is this all to end? Are we turning the world into a big rubbish dump(堆存处)，or is there any hope that we can get rid of (摆脱，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.
    The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.
    小题1:Which of the following is NOT true according to the passage?
    A．We live on the earth, so we should look after it.
    B．Man is fighting against different kinds of pollution.
    C．To pollute means to make air, water and land unfit for use.

    B．the increase of population caused more waste.
    C．there isn’t any hope that we can get rid of the pollution

    Like schools in China, American schools begin in September after a long summer vacation. The first term is from September to January and the second is from February to June. Usually American children begin to go to school when they are five years old. Most students are seventeen or eighteen years old when they finish high school.
    But unlike middle school students in China, high school students in America take only four or five subjects each term. They usually go to the same classes every day and have homework for every class. After class they do all kinds of interesting things.
    After high school, many students go to college. They may go to a small or a large one. They usually have to pay a lot for their higher education. So lots of students work after school to make money for their studies.
    小题1:In America, summer vacation lasts（持续）___________________.

    Are some people born clever, and others born stupid? Or is intelligence (智力) developed by our environment and our experience? Strangely enough, the answer to these questions is yes. In some degree, our intelligence is given to us at birth, and no education can make a genius (天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich environment. Therefore, the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This point of view, now is held by most experts.
    It is easy to show that intelligence is something that we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. If we take two strangers by chance from the population, it seems that their degree of intelligence will be completely different. If, on the other hand, we compare two twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
    Imagine now that we take two twins and put them in different environments. We might send one, for example, to a university and the other to a factory separately where the work is boring. We would soon find differences in intelligence developing, and this shows that environment as well as birth plays an important role. This conclusion is also suggested by the fact that people who live in close contact (接触) with each other, but who are not related at all are likely to have similar degree of intelligence.
    小题1:How is man’s intelligence given?
    A．At birthB．Through education
    C．Both at birth and through educationD．Neither at birth nor through education
    小题2:What does the underlined word mean in the first paragraph?
    A．稳固B．确定C．修理D．安排
    小题3:According the passage, if a child is born with low intelligence, what might happen to him later?
    A．Become a genius.
    B．Still become a genius if he should be given special education.
    C．Reach his intelligence limits in rich environment.
    D．Never reach his intelligence in his life.
    小题4:What can we learn from the example of the twins going to a university and to a factory?
    A．The importance of their intelligence.
    B．The role of environment on intelligence.
    C．The importance of their jobs
    D．The part that birth plays
    小题5:What statement is TRUE according to the passage?
    A．No education can help make a genius.
    B．Personality is important as intelligence which was given to people at birth.
    C．People who have similar degree of intelligence must be relatives.
    D．Environment influences people in intelligence developing.

    根据短文内容，选择正确最佳答案。
    American Classroom Rules
    1. If the teacher asks a question, you should give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you don’t know the answer, it’s all right to tell the teacher that you don’t know. Then he or she knows what you need to learn.
    2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility（责任）to find out what homework you have missed. It is not the teacher’s job to remind you of missed homework.
