How often one hears children wishing they were grown-ups. And old people wishing they were         again. Each age has its pleasure and its pains, and the happiest person always enjoys what each age       him without wasting his time in useless regrets.  
Childhood is a time when there are       responsibilities（责任）to make life better. If a child has good parents, he is raised, looked after and loved, whatever he may do. It is        that he will ever again in his life be given so much without having to do anything in return. But a child has his     . He is not so free to do what he wishes to do. He is        being told not to do something, or being punished for what he has wrongly done.   
When a young man starts to earn his own living（谋生）, he can no longer expect others to     his food, his clothes, and his room, but he has to work if he wants to live      . If he spends most of his time       in the ways 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 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.
