我的改变 How I've Changed

Since I go to middle school, I found the lifestyle is so fast that I have to study much harder. Before, I would go shopping or playing sports with my friends after class. At night, I would watch TV or chat with my friends online, but now, the situation has changed. In the day time, I have to sit in the classroom to study so many subjects and at night, the homework takes up my whole night. I start to feel stressful. I realize that I need to get used to the new life. If I can improve my study efficiency, I can make out some time to have fun. 
自从我上中学后，我发现生活节奏是如此的快，我要更加努力地学习。以前，课后会和我的朋友去逛街或做运动。晚上，会看电视或和朋友网上聊天，但是现在，情况已经改变了。白天，我坐在教室里学习很多科目，晚上，作业占据了我所有的时间。我开始感到压力，我意识到我需要适应新的生活。如果我能提高学习效率，就可以有时间玩耍。
