     How often one hears that children wishing they were grown-ups and old people wishing they were

young again!  Each age has its pleasures and pains, and the happiest person is the one who enjoys what

each age gives him without wasting his time in useless regrets.

     Childhood is a time when there are few responsibilities to make life difficult. lf a child has good parents, he is fed, looked after and loved, whatever he may do. 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 parents. 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 he 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.

推进城镇化,要注重城镇化质量,避免“快而不优”,“大跃进”式的推进,切忌“贪大求洋”、“千城一面”,粗放发展。试就此对我国城镇建设提出两条方法论建议。
