可爱的孩子。。
你就写：音乐是洗涤心灵的良药~而我却在音乐课上与同学讲话。。。我深感愧疚。作为文明的中学生，就要遵守行为规范，不在课堂上讲话。所以我向老师保证，在以后无论是在音乐课，还是其他几门课程，专心听老师的教诲，，。等等。。

I'm wrong. I'm really wrong. I should not talk in the music lesson. If I don't talk, I will learn more better and other students will learn better too. Oh! Teacher! Please forgive my false. I will never talk in the lesson again. That's all. Thank you.
