The author advocates that competition for high grades seriously limits the quality of learning , which evokes a fierce discussion recently. Surely, the competition for high grades brings enormous problems such as cheating and pressure. However, in my point of view, this competition is still significant to all levels of education. Firstly, score is just like a ruller that gives all levels of schools-whatever high schools or colleges-a standard to evaluate their students and test an individual's ability to decide whether he is available for the school.Since the quality of students is one of the most important determinants of a school in last years, the competition for high grades arranges the different  levels of students by their results that the school can choose.Moreover, such a standard also provide a path for teachers to estimate their educative results.For instance, the arrangement of scores will clearly reveal both the best and the worst group of students in a class, by which a teacher can reflect the methods in his or her teaching and then consummarate it. Secondly, although upon these competitions,students may suffer a unavoidable pressure,to the extent, it  is possible to cause considerable social problems, the competition is still significantly beneficial to the education for it can inspire the students to make more efforts for their future as a catalyze. It is like that the scores is not only a standard, but also a encouragement and a reward.As the ancient Chinese saying "there must be brave men under rewards", this mechanism of reward ensure the students striving for their goals. On the other hand, it would be horrible if we lose this competition.The more harmful thing than the negative effects the competition  may bring is that we don't have the competition.It is not only for education , but also for the society. Although, a large amount of problems have been brought by the competition , such as, many try to cheat in exams for a high grades or some kill themselves under a remarkable pressure,the competition itself is not responsible for that unhealthy environment. Since the intention of the establishing of the competition is benign, what we should do is creating a nice environment for such a competition and make it a benign circulation. In sum,the competition for high grades is something indispensable either for today's eduacation or the society that we can not abandon.Moreover, a good environment is another support for the improving of learning that we need to create by our own.
