| These days it is found that school students hardly have any sports. Is it because they have no 1 in sports? It may not be true. They often say they have 2 more important things to do. What are these important things? Exams! They have to get themselves ready for all kinds of exams and tests in school, so many of them almost 3 bookworms. In the past in the summer holidays, they could do 4 they like, but now they have to spend all their free time preparing for exams. So 5 have kept them away going in for sports. Because of the pressure (压力) from their parents and teachers, they have to work harder and spend most of their time 6 books. As for the students themselves, they don't want to fail the exams because they want to continue their 7 studies. So it becomes necessary to give 8 of their spare time to their studies and 9 up their school sports. It is true that a good education cannot go without physical training, and the same is true that a quick mind hardly goes along without 10 body. Without a strong body, you can never do anything well, then how can you make great success in life? |
