Nowadays, after-class activities are becoming more and more popular in high schools. In our school, there are various kinds of activities and we enjoyed them very much. Playing football is my favorite, which do me lots of good, such as building my body and keeping me healthy. Beside, it also frees me from the heavy work of study.
Here I have some advices. To students, you’d better to choose the activities which interest you and suit you; to schools, they should organize more activities for students, leave students time for activities by giving them more homework.
Dear friends, please actively take part in after-class activities, what will not only make your school life colorfully, but also improve your learning.
