When I get into a middle school, it means I have grown up. So I will try to do better in everything.

First of all, I should learn how to learn. It will help me study easily. Then I will get on well with my classmates and help each other. At last I want to continue my hobbies, such as reading, dancing and playing tennis.

I believe I can.

首先我要学会怎样学习，这会使我学习的更轻松。其次，我要和同学友好相处，互相帮助。最后，我还想继续我的爱好，例如：阅读、跳舞和打网球。

我相信我能行。
