Today we find that school students hardly spend much time on sports. Is it because they aren’t interested in sports? No, they often say they have other important things to do.

What are these important things? Tests! They have to spend much time on all kinds of tests at school. So many of them almost become bookworms(书呆子) . Books stop them from going out 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 the students, they want to get good results in order to improve 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 body exercise, because a quick mind hardly goes along with a weak(虚弱的) body. If you don’t have a strong body, you can never get anything or any great success in your life.
