　　Generation gap between parents and children

　　Nowadays , there are more and more misunderstanding between parents and children which is so- called generation gap . It is estimated that (75 percentages of parents often complain their children’s unreasonable behavior while children usually think their parents too old fashioned).

　Why have there been so much misunderstanding between parents and children?

　　Maybe the reasons can be listed as follows . The first one is that ( the two generations, having grown up at different times, have different likes and dislikes ,thus the disagreement often rises between them) . Besides(due to having little in common to talk about , they are not willing to sit face to face ) . The third reason is (with the pace of modern life becoming faster and faster , both of them are so busy with their work or study that they don’t spare enough time to exchange ideas ).To sum up ,the main cause of XX is due to ( lake of communication and understanding each other) .

　　It is high time that something were done upon it. For one thing (children should respect their parents ).On the other hand ,( parents also should show solicitue for their children). All these measures will certainly bridge the generation gap.
