[答案]

　　　　　　　　　　　　　　　　 Failure is the mother of success

　 The writer tells us about the reasons for people's fearing failure and describes some ways on how to deal with failure as well as our attitude toward failure.

　 We middle students should have an active attitude towards failure. As we know, failure is a common thing in one's life. Almost everyone experiences failure in his life. When one fails in his attempt to do something, he often feels upset. Some people may give in to failure. But others will stick to it and achieve the final success.

　 As the old saying goes, "Failure teaches success." It is true that failure is an important factor towards success. The way to success is full of various difficulties and obstacles. Many important inventions or discoveries were achieved after hundreds of failure. We know the fact that many failures made Thomas Edison a great inventor in the world. And only those successes, which have been achieved after many failures, are really valuable and praiseworthy.
