Questions 19-25

·For questions 19-25, choose the correct answer from A, B, C and D.
·Markyour answers on the Answer Sheet.
It is natural for young people to be critical of their parents at times and to blame them for the most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern way; that they are possessive and dominant; that they don’t trust their children to deal with the crisis; that they talk too much about certain problems — and that they have no sense of humor, at least in parent-child relationships.
I think it is true that parent often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parent with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from adult world into which they have not yet been accepted. So they create a culture of society of their own. Then, it turns out that their music and entertainers 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 they are leaders in style and taste.
Sometimes you are resistant, and proud because you don’t want your parents to approve what you do. If they did approve, it looks as if you are betraying your own age group. But in that cases, you are assuming that you are an underdog: you can’t win but at least you can keep your honor. There is a passive way of looking at things. It is natural enough after long years of childhood, when you are completely under your patents’ control. But it ignores the face 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 your parents with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.
