(D)

　　Oftentimes one hears children wishing they were grown-ups, and old people wishing they were youngsters 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 things.

　　Childhood is a time when there are few responsibilities(責(zé)任) to think about. A child is usually fed, looked after and loved by his parents. He will never be expected to do anything in return. Also, life is always presenting(星現(xiàn)) new things to a child, but the things that have lost their appeal for the old because they are too well-known. In the meanwhile, a child has his pains: He is not so free to do what he wishes to, he is continually(不斷地) being told not to do a certain thing, or being punished for what he has done wrong.

　　After a child grows up. he starts to make his own living. He can no longer expect others to pay for his food, his clothes, or his room, and he has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to play 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 in prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up his own position in society.
