My spare time is full of interested activities. I read all kinds of books in the reading room whenever I have time. In this way I learn much in the library than in class. Moreover, I took part in many sports activities, of that my favorite is basketball. I often play basketball after the school. Sports and games keep me health and energetic enough to overcome a variety of challenges. Sometime I go in for social practice with my classmates outside school. Thus, I can gain much social experiences. Out-of-class activities are quite necessary for our students. Through these activities we can lean that cannot be learned in class.
