阅读表达(共5小题;每小题3分,满分15分)

阅读下面的短文,并根据短文后的要求答题。(请注意问题后的字数要求)

[1]When we were children, it seemed that father knew everything. When we grew up and father became older, sometimes we quarreled about our own views. So I try to get on well with father.

[2]Remember the age of father. Being aware of father’s age will help us to understand him better. He has lived in the years when attitudes towards matters, such as poverty, unemployment, higher education, were quite different from those in our time. Thus it is impossible for him to change mind totally.

[3]Listen to father. As we grew up, what our father has told us often sounds not sophisticated(圆滑的)enough from the world we live in today. Yet I have found that sometimes the words that my father told me long time ago are remarkably useful. If father knows we respect his point of view, even if we do not share it, it will help him feel close to us.

[4]Remember that father has a past. When he was young, he lived a hard life. He came from remote village. How to stay in a strange city and how to earn money are problems he met first. He must work hard and face all kinds of difficulties. Full of wisdom, courage and hope,   

                    at last. It is a part of his life that must have affected him deeply.

[5]Accept personality from father. Most of us have mixed feelings about taking after our father. We might feel fine about it when we are considering his admirable qualities. But we have realized that we and our fathers share those characteristics we do not admire. Accepting what we have inherited(继承)is important.

[6]Adopting any approach to get on well with our father is the issue of how we manage ourselves. We should keep a sense of humor with our father. Remember we will have our own child and surely we will be parents. Accepting and understanding our father is a part of our life.
