I am sorry for my talking last time in the class. In the class, I should not talk on and on. No matter what happened at that time, I should listen to the teacher carefully. Besides, I should try to understand what the teacher is talking ,and do my best to remember the knowledge I can understand instantly. After clss, I must do my homework carefully and review what I have learned in the class. Only in this way can I get a high score in the exam. I'm already in Grade x, I should recognise what I should do and what I can do now. However, I forget this at the moment. Now I understand I should study hard now. I promise I will study hard later. I will never make the same mistake from now on. I hope you can forgive me, Miss X. And please watch over me. Thank you.
