E    Is Failure a Bad Thing、    Failure is what often happens.    65    Students may fail in exams, scientists may fail in their research work, and athletes may fail in competitions.    66    Some people don’t think their failure is a very important thing at all. So they pay no attention to it. As a result, they will have the same failure some time later. Some think themselves are fools and lose heart in everything after they fail. Consequently, they spend their time and energy on useless things and they may really be fools.    Other people are quite different from the two kinds of people mentioned above. Instead of being upset and lost, they draw a lesson from every failure and become more experienced.  67  It is said that failure is the mother of success. Success will be gained after times of failures so long as we are good at drawing lessons from our failures.    68    The really bad thing is taking a failure as failure or even losing heart after failure.根据短文内容，从A、B、 C、D和E中选出最适合放入短文空缺处的选项。选项中有一项是多余的。
