     Like most big projects, learning to manage your mother well is what you should do. Here are what I

believe the best steps towards a better relationship with her. They are not necessarily surprising or

revolutionary, but they have worked for many people. Try them.

     Remember your mother's age. As children, we often do not think of our mother as having an age.

Even when we become conscious of her as an individual, age does not change our view; she is still our

mother. Knowing our mother's age, not just in numbers of years but in terms of her psychological and

physical state, often helps us to understand her better.

     Listen to your mother. I have found that sometimes the things my mother told me long ago are

remarkably useful. If your mother knows that you respect her point of view, even if you do not share it,

it will help her feel close to you.

     Remember that your mother has a past. A key step in managing our relationship with our mother is to

find out about her early life.In learning about our mother's past, we know that it can encourage us to think

about her whole life.

    Ask your mother about your childhood history. My grandparents died when I was young. If you are

fortunate enough to have living family, think of your life as a jigsaw puzzle and ask as many questions as

you can to put the picture together. Understanding your roots and your childhood can help you know

more clearly who you are, as part of a family which you share with your mother.

     Remember that managing your mother is really about managing yourself. Taking any measure to

managing our mother is the issue of how we manage ourselves. No matter how difficult we find her, it is

important to remember that it is not her behavior itself that is causing us discomfort, but the way we feel

about her behavior. We should follow the way of her life. At the heart of managing your mother is being

able to accept your flawed self. Only then are you able to accept your mother-with all her failings.

1.What does the underlined phrase "a jigsaw puzzle" mean?

A. 拼图玩具  

B. 浏览迷宫  

C. 填充字谜  

D. 游戏人生

2.Which of the following is implied but not stated in the passage?

A.You will have a better relationship with your mother if you respect her opinion.

B. Knowing your mother's age is a useful piece of advice.

C. The key measure of managing our mother is how we manage ourselves.

D. It is unreasonable to expect our mother to change totally from the way she was brought up.

3. The main purpose of writing the text is _______.

A. to give information about how you think of your mother

B. to improve the relationship with your mother

C. to keep a sense of humor about your mother all day long

D. to accept your mother-----with all her failings
