When I go to school, teachers always tell me that we should make used of time and study hard. I don't put it in my heart. But when I realize my classmates are making big progress, I know I have wasted a lot of time to improve myself. So from now on, I must study hard and learn as much knowledge as possible.

　　我一开始去学校的时候，老师就不断的告诉我要好好利用时间，努力学习。我没有把这些话放在心里，但是当我意识到我的同学正在取得了很大的进步时，我才知道我浪费了很多时间去提高自己。所以从现在开始，我必须努力学习，尽可能多的学习知识。
