nowadays,high school students hold different opinions about after-class activities.there are two quite different phenomenonena.

　　some students are crazy about sports and some other activities.they spend much time in joining the outdoor activities and varies of groups , and also,making new friends.however,they pay a little attention to their studies.

　　on the contrary, some students spend almost of their time in studies and don't enjoy attending other activities.

　　in my opinion,i think neither of them is correct.i think we should study hard,but we also need time to relax ourselves,because if a one in a good state,he can do better.
