This reports shows something of home computer use by a group of young people. It is a common idea that children today know about computers and have a good knowledge of using them in all sides of their lives. We decided to try to find out whether this was true.

　　We asked thirty young people between 14 and 18. All the children said they had computers at home. We asked them how much time they usually spent on their computers in a week, but we were most interested in what they used their computers for.

　　The usual time spent on a computer in a week was about 12 hours, with the highest user about 32 hours and the lowest user only 5 hours. There was no great difference between boys and girls.

　　All the children said they usually used the computer to play games. Fourteen told us they did some wordprocessing(文字处理) at home, but not very much. Only 2 of them said that computers helped them with their studies, and 8 people told us they kept addresses and telephone numbers on their computers or used them as diaries. Only 3 people said they were learning to make computer programmes, and nobody looked up databases(数据库) (other than their address lists). None of the people used their computers for any other use. The diagram(图表) gives all the results one by one.

　　The results show that computer use is quite high among 14-18 year-old children. They also show quite clearly that computers are seen by most young people as little more than games machines. The only other great uses are for wordprocessing and keeping address lists. It seems to us that, though computers are common in the homes of young people, they have not yet become useful in everyday life.

[　　]

A．3 people between 14 and 18.

B．Only 2 of the group.

C．To help them with their studies.

D．To help them with computer programmes.

2．We are afraid there is one mistake in the diagram What is it?

[　　]

A．the words “Number of people” and “Computer use” should be changed each other.

B．Add all the numbers from “a” to “g”, the number should just be 30.

C．The number of “d” should be higher.

D．There should be not number about “f”.

3．In the report, “little more than” means ________.

[　　]

4．If children could use computers usefully, that means ________.

[　　]

C．there would be great different between boys and girls

The world is divided into two parts. One half of the world is rich and   26  is poor. In the poor part, a lot of people have  27 got enough to eat. When they are ill, none of the   28 can receive them because they have no money. In the rich   29 , people eat very well,   30 a dog or a cat in North America eats   31 than a child in poorer countries.
The poor countries have some difficult problems. Sometimes the land is too poor to grow  32 on. People there have   33 rich land nor enough water. The land   34 be made better, but a lot of things must be done. The people must be taught and water must   35 .
But rich countries have problems, too. There are not always good places to   36 . Sometimes the air is not clean and the rivers are too   37 to swim in or to drink. The roads and streets are full of people and cars. Cars and buses have to move   38 . Noise is too much. Some people have no houses to live in. Something must be done about these problems. The air and the rivers must be cleaned and be   39 clean. More houses have to be built.   40 these things cannot be done easily.
