Recently the issue of students’ study has been brought to public attention. Students are anxious about how to improve their scores. Some work very hard. They spend all their time on study. They do nothing except study. As far as I’m concerned, it is not a good way to study. Alternate work with rest is the best to study well. Students should try their best to learn knowledge as Francis Bacon said,”Knowledge is power”. However, they should have other recreational activities to relax themselves. Because people can do things more efficient after relaxed themselves’s more, people can obtain knowledge from many sources besides books, which is beneficial for study. Thus, combine exertion and rest is the best to study.
