书面表达

We middle school students have had many tests or exams. We have both achieved success and suffered from failure. Different students take different attitudes to failure. Some fall in low spirits when they don't do well in the exams. They usually lose heart and no longer study as hard as before. But most students take an active attitude towards failure. They encourage themselves to be self-confident. They find out and analyze the causes so that they will no longer make similar mistakes. I agree with those with active attitudes. As we all know, failure is the mother of success. Even great men may have failed many times before they succeeded. So in my opinion, it’s not important whether we succeed or not. What matters much is what attitudes we should we must deal with our failure correctly.
