     People make good use of time in America. Americans think much about time, and from childhood they

learn to value time.As children, they are taught to be on time to go to school,to walk and to do everything. When they are having a good time, they say that time goes easily.  When a person is dying, they say he is

living on a borrowed time.

     Time is money. Time is knowledge. Time is everything in America. A working American has to work

hard for eight hours a day or forty hours a week,and this is the working time.In his free time,he also works hard for more money. Even on Saturday and Sunday he also works as usual. In the street you can hardly

see a man walking slowly. They walk very fast. In fact, they are running.

time, because they feel they have become servants of the clock.
