Cities can be frightening places. The majority of the population lives in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of flats. Children become aggressive and nervous—cooped up at home all day, with nowhere to play; their mothers feel isolated from the rest of the world. Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on tire same floor in tower blocks don't even say hello to each other. Country life, on the other hand, differs from this kind of isolated existence in that a sense of community generally binds the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. But country life has disadvantages too. While it is true that you may be among friends in a village, it is also true that you are cut off from the exciting and important events that take place in cities. There's little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-dweller who leaves for the country is often oppressed by a sense of unbearable stillness and quietness. What, then, is the answer？ The country has the advantage of peace and quiet, but suffers from the disadvantage of being cut off; the city breeds a feeling of isolation, and constant noise batters the senses. But one of its main advantages is that you are at the centre of things; and that life doesn't come to an end at half past nine at night. Some people have found(or rather bought) a compromise between the two: they have expressed their preference for the "quiet life" by leaving the suburbs and moving to villages within commuting distance of large cities. They generally have about as much sensitivity as the plastic flowers they leave behind—they are polluted with strange ideas about change and improvement which they force on to the unwilling original inhabitants of the village. What then of my dreams of leaning on a cottage gate and murmuring "morning" to the locals as they pass by？ I'm keen on the idea, but you see there's my cat, Toby. I'm not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm？ No, he would rather have the electric imitation-coal fire any evening. One of the disadvantages of living in high-rise buildings is that ______. A．the parents may become violent and difficult to put up with B．the residents may not have a good view from their windows C．the residents may become indifferent to their neighbors D．the children may become too frustrated to be controlled

These crimes are not usually committed by people who are poor or in need. Young people often dislike and hate the adult world. They will do things to show that they are rebels. Also in Britain today it is easier for young people to commit crimes because they have more freedom to go where they like and more money to do what they like. There are two other possible causes which are worth mentioning. More and more people in Britain live in large towns. In a large town no one knows who anyone else is or where they live. But in the village I come from crimes are rare because everyone knows everyone else. Although it is difficult to explain, I think the last cause is very important. Perhaps there is something with our society which encourages violence and crime. It is a fact that all the time children are exposed to films and reports about crime and violence. Many people do not agree that this influences the young people, but I think that young people are very much influenced by the society they grow in. I feel that the fault may be as much with our whole society as with these young people. 6. From the passage we know that many British people are confused about (). A. the cause of juvenile crimes B. the rise of the crime rate C. the problem of crimes in their country D. the various kinds of juvenile delinquency 7.
