When I was in Grade 7, I used to spend too much time chatting online at night. The next day, I often felt(困倦的) in class, I couldn't listen to teachers carefully and I couldn't  (重复) correctly what the teachers told me. I （几乎不） understood what they taught in class. That was why so much homework couldn't (做) by me because of my terrible situation at that time. And my mother always (警告) me of the importance of my schoolwork. From then on, I (开始)studying for my most important exam in my life. I have realized that it's （愚蠢的）of me to do that. I listen carefully in class every day. At night I read some books after finishing the homework to be knowledgeable. I feel like studying with my teachers and classmates I'm the （主人）of myself. I have made a little progress and I think I (赢了) the war against my laziness. I'm no longer a fool , which once worried my parents a lot in the (过去).

      There is an old saying: He who laughs last laughs best. I hope I could enter my ideal high school.
