VI.阅读表达(共5小题;每小题2分,满分10分)

阅读下面一篇短文,然后按照各小题的题目要求和括号内的词数要求回答问题。

People say teenagers are no good. They make too much noise in shops; they drive wildly up and down the streets. And at times, some of these things are true. But there are also hard  moments in the life of a teenager

A teenager is neither a lovely child, nor a respectable grown-up person. The numbers of his family consider a teenager a source of trouble. He feels that he has grown up. But he is told that he is just a child and he knows nothing. He sees his elders doing what they like. When he _______, the elders tell him that he should do only what he is told to do. To be a teenager means to be everybody’s servant and nobody’s master. Elders in the family and in the neighborhood order a teenager to run errands(跑腿)for them. If he refuses to carry out the orders, he is scolded. He may even be punished. He is criticized for all that he says and does. If he behaves like a child, he is told that he is grown-up and that he should not be childish. If he behaves like a grown-up man, he is told that he is disrespectful(无礼的).

A teenager becomes a lonely creature in the family. Children enjoy all the

love of the elders in the family. The teenagers get no love and no respect. So they often run away from home and find some joy in the company of the other teenagers of their age.

The trouble with teenagers is that they haven’t learnt to controlled and there are too many rules and regulations for them to obey. Although they teenagers have a miserable time with their family members and elders, they have a very good time with their friends in schools and colleges. So they spend most of their good time and have fun with their friends and classmates rather than with their parents.
