    參考范文：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. The possible 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 that 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 the gap is due to lake of communication and understanding each other.

    It is high time that something was done upon it. On the one hand， children should respect their parents. On the other hand， parents also should show solicitudes for their children. I firmly believe that all these measures may bridge the generation gap.

    It is recognized that environmental pollution has been a greatly serious problem. Many plants， animals and people have died of polluted environment. Therefore， environmental pollution should be responsible for these diseases disabling， or bringing death to human beings and wild life.
