     America is a society in which children have watched about 18,000 television commercials (商业广告)

by the time that they have reached their middle teens. My friend Jolie learned this fact a few weeks ago and

decided to do something about it. She thinks that the number of commercials that children see can influence

the way in which they view the world. That is, Jolie believes that children who watch so many advertisements

will grow up to believe that the most important thing in life is to buy, buy, buy! This, says Jolie, is wrong. A

little child cannot understand advertisements for what they are and so believes totally in what he or she hears.

     I have been thinking about what Jolie has told me. I suppose that she is right. I know that it is easy to

control the minds of children because they don't see things logically as adults do. And I am upset myself at

how the advertisers can control a child's outlook on the world. I think I should join Jolie in her efforts to

change advertising methods when it comes to advertisements for children. I really have a responsibility (责任)

to make sure that future generation are given every chance to develop their minds without being influenced by

anything bad.

     Of course, there is another side to the problem. After all, parents ought to take responsibility for what their

children watch and how much television they see. I know that many parents just want their children to be quiet,

and so they let them watch as much television as they want. But,in the long run,the methods of advertisers have

great power because we are society of consumers (消费者). I only hope that someday there can be an answer

of this problem. Children need our guidance, not the guidance of advertisers.
