题型描述: 阅读理解How often one hears children wishing they were grown up, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.Youth is a time when there are few tasks to make life difficult. If a child has good parents, he is fed, looked after and loved. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child—things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things, or being punished for what he has done wrong.When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.1、 People can experience happiness if they _ _ _ _ _ _ . A. value the present B. always think of the past and regret it C. are no longer young D. become old and have much experience 2、 When people were young, they used to _ _ _ _ _ _ . A. have few things to think about and take on B. look after their younger sisters and brothers C. face a lot of difficulties D. be in charge of many business 3、 The pains of children lie in the fact that _ _ _ _ _ _ . A. they can not be accepted and praised by others B. they are often beaten by their parents C. no one helps them make right decisions D. they are not allowed to do what they like to do 4、 Children are usually happy because _ _ _ _ _ _ . A. they are familiar with everything going on around them B. old people lose interest in them C. things are new to them D. they are free to do wrong 5、 Which of the following is NOT needed for a young man to be happy? A. Health. B. Being free from troubles. C. Hard work. D. Wealth.统考英语A
