Examination(考试)
Someone says examination can help us go over our lessons in time and after the examination we can find how we are getting on with our studies.But we are always having too many examinations and they are also too difficult for us to get through.I find some of us have lost interest in learning lessons.Besides,it is harmful to our health as we hardly have any time to go in for sports.I think the present system of measurement should be improved.

有人说考试可以帮助我们复习功课，考试后我们可以找到我们学习的方式。但是，我们总是有太多的考试，他们也太难了，我们很难通过。我发现我们中的一些人已经失去了学习的兴趣。此外，它对我们的健康有害，因为我们几乎没有时间去参加体育运动。我认为目前的测量系统应该得到改进。
