I would spend the most of my PE lesson to exercise rather than study in class. There are various activities, such as playing table tennis, playing football and so on. While, I just love running, especially the long-distance running for it exercises my endurance and perseverance.Not only it is beneficial to prevent and cure diseases, but it can alleviate my pressure from study.

So, every time I have difficulty in my study, I always run on the playground for relax. Then I would feel better and focus on my study again.

我会把大部分的体育课花在锻炼上而不是在教室里学习。有各种各样的活动,比如打乒乓球,踢足球等等。然而我只是喜欢跑步,尤其是长跑因为它可以锻炼我的耐力和毅力。它不仅有利于预防、治疗疾病,而且它可以缓解我的学习压力。

所以，每当我在学习上遇到困难时，我总是在操场上跑步放松。之后我就会感觉好点，专更加注于学习。
