6.根据短文内容，选择正确的答案。

B

In your life, there are a lot of people around you. They are your relatives, neighbors, friends or classmates. Sometimes you get along well with them, but sometimes don't. What can you do when someone hurts you? Most people may be angry or even fight with him. But it's not a good idea. You'd better forget all this and forgive (宽恕) him.

Maybe it's not easy for you to do that, but it's possible. Please remember: Keep a good mood, and you will keep healthy. Staying angry with others, in fact, means letting others' mistakes treat yourself unfairly.

How can you forgive others?

First, think of something pleasant and try to get yourself happy.

Second, don't wait others to say sorry to you. If anyone hurts you, he won't say sorry to you. He may just want to hurt you or just don't see things the same way.

Third, try to see things in others' shoes. You can understand their minds better and make yourself a little happier.

At last, try to know yourself very well. Whose mistakes caused that, yours or others'? If it's your fault (错误), try to say sorry to them. If it isn't, smile at the thing.
