英语翻译
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.
