第三篇
It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained,more or less justly,that their parents are out of touch with modern ways;that they are possessive and dominant;that they do not trust their children to deal with crisis;that they talk too much about certain problems;and that they have no sense of humor,at least in parent-hild relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles,in entertainments and music.This is not their motive.They feel cut off from the adult world into which they have not yet been accepted.So they create a culture and society of their own.Then,if it turns out that their music or entertainments or vocabulary or clothes or hairstyles irritate their parents,this gives them additional enjoyment. They feel they are superior,at least in a small way,and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do.If they did approve,it looks as if you are betraying your own age group.But in that case, you are assuming that you are the underdog:you can't win but at least you can keep your honor. This is a passive way of looking at things.It is natural enough after long years of childhood,when you were completely under your parents' control. But it ig而res the fact that you are now beginning to be responsible for yourself.
If you plan to control your life,cooperation can be part of that plan.You can charm others,especially your parents,into doing things the way you want.You can impress others with your sense of responsibility and initiative,so that they will give you the authority to do what you want to do.

[单项选择]Danny was just tired about the way things were going. His mom came to the school and went on and on talking about Rick Jackson. It seemed that she would never stop talking. "Somebody’s got to stop that boy!" she was shouting, "Rick’s troubling everybody in the neighborhood. And he loves to pick on little boys like Danny."
Mrs. Green, Danny’s teacher, was concerned a lot. "I didn’t know that Danny was being picked on," she nswered. "He’s never said anything about this to me!" Mrs. Green looked at Danny. "How long has this been going on" She asked. Danny could only shake his head and look at the floor. He knew if he said a word about this, he would have trouble after school.
