Each age has its pleasure and its pains, and the happiest person is the one who enjoys what each age ( 22 D ) him without wasting his tine in useless regrets.Childhood is a time when there are few responsibilities(责任) to make life difficult If a child has good parents,he is raised,looked after and loved,whatever he may do.It is impossible.that he will ever again in his life begiven so much without having to do anything in return.what s more,life is aways giving new thing to the child-things that they have lost their ( 23 D )for older people,because they are too ( 24 C ). But a child has his pains,he is not so free to do what he wishes to do; te is again and again being told not to do something, or being ( 25 A ) for what what he has wrongly doneWhen a young man ( 26 B ) to earn his own living,he can no longer expect others to ( 27 B ) his food,his clothes and his room but has to work if he wants to live ( 28 A ) if he spends most of his time playing about in the ways that he used to as a child,he will ( 29 C ) hungry. And if he breaks the laws of society ( 30 D ) he used to break the laws of this 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 hinseif his position in society.21.A children B young C active D strong22.A leaves.
