阅读短文,根据要求完成下面各小题。

     Failure (失败) is a part of life. No matter what we do, there are always two results: success and failure.

There is no doubt (怀疑) that every one of us wants to be successful, but we can't always avoid failure.

     People have different opinions about the failure. Some people regard failure as a bad thing. They hold

that they should always do everything well. If they fail in something, they will lose their confidence. Other

people regard failure as a chance to learn. They redo (重做) what they failed to do. They know complaining

won't help themselves.

     As an old saying goes, "Failure is the mother of success." As long as we keep to what is right and correct

what is wrong in time, we will have success. In my opinion, failure is not bad, it's not good, either.
