　　Should Examination Be Abolished （取消）？

　　The examination system has come to be the main theme （主题）of modern education. One should take an examination andsucceed in passing it before he could be admitted， promoted or graduated. As it plays so important a role in the realm of education （教育的领域） it is under much criticism （评论） as to its validity （有效性） . People who are in favour of it try to develop this system more； those who are against it believe that such a system should be abolished. Should examination be abolished？ In my opinion it should be.

　　Many people think that an examination is the only means to test knowledge， but， in fact， that is not true. A few questions given in an examination could by no means cover the whole field of the subject. Thus those who are able to answer them may be the poorest of the students and yet happen to know just a few points about that subject.

　　I'd like to say that， because of the existence of the examination system， students pay so much attention to gaining high marks， that they often forget the chief purpose of education. The so-called clever students devote （贡献） themselves to the study of textbooks only. They， of course， know nothing but the skeleton （梗概） of knowledge. The end and aim of education， however， is to enable students to learn how to live. To do this， students must get themselves to do all kinds of training， physicalas well as mental. The present examination system has discouraged students from making such an attempt.

　　Moreover， since the students try so hard to put their lessons into memory in as short a time as possible， psychologically （心理上来看）， they soon forget the whole subject as soon as the examination is over. Surely this is one of the greatest wastes ever made in the history of civilization.

　　Lastly， in order to get high marks， there is a great temptation （诱惑） for students to cheat （作弊） in an examination. Indeed， such a practice becomes the means to the end. They cheat their teachers， their parents and also themselves. Such a tendency would impair （损害） our moral standards （道德标准） .

　　Therefore， I am of the opinion， in conclusion， that the examination system should be abolished.
