Today it is found that school students hardly pay much attention to(注意) sports.Is it because they aren’t interested in sports?No.They often say they have other more important things to do.
What are these important things?Examinations!They have to spend much time on all kinds of examinations at school.So many of them almost become bookworms(书呆子).Books stop them from going in for sports.Because of the pressure from their parents and teachers,the students have to work harder and spend most of their time on books.As for(就……而言)the students,they want to get good results so that they can further their studies.So it is necessary for them to give all of their free time to their studies and stop their school sports.
In fact,education can’t go without physical exercises,because a quick mind hardly goes along with a weak body.If you don’t have a strong body,you can never achieve(获得) anything,let alone(更不用说) a great success in your life.
