We asked thirty young people between 14 and 18 several questions. All the children had computers at home. The average time spent on a computer in a week was about 12 hours, with the highest about 32 hours, and the lowest only 5 hours. Most children said they usually used computers to play games. Fourteen children told us they did some word-processing(文字处理) at times. Eight people told us they kept addresses and phone numbers on their computers or used them as diaries. Only three people said they were learning to write computer programs and nobody used databases(数据库). Only two of them said computers helped with their lessons. The diagram(表格) gives all the results one by one.

    The results show that computer use is quite common among 14-18-year-old children. They also show quite clearly that computers are seen by most young people as little more than game machines. It means to us that, though computers are common(普遍) in the homes of young people, they have not yet become popular in everyday life.

Many years ago, people lived a hard life. They couldn't use modern machines, because there was 1one at that time. Today people have a better life but there are new problems. One of biggest problems is it has 2our rivers and lakes dirty. It kills our fish and affects our 3water. We call it water pollution. Noise pollution makes us talk more 4and become angry 5. Air pollution is the most serious kind of pollution. It affects all living things in the world. Machines and factories 6our air every day. Sometimes the pollution is so 7that it is like a blanket (毯子)covering a city. Many countries are making new laws to reduce pollution. We must clean 8water before we 9them into some place. We need to do many other things to protect our environment. We must put rubbish into dustbins 10throwing them about. We can go to work by bus, on foot, or with friends in a car. If we do like that every day, our environment will be better.
