老师给学生的回信

My Dear Teacher:

Let me tell you something about how to improve the effectiveness of study. I think the key to improve the effectiveness of study, especially English, is to improve your teaching methods. I think you need to spend more time explaining to us these English sentences and not cutting the corners. Let me tell you something, the last time the other teacher did not do well and her students failed, she was told to leave and find another job. Please don't take this as a threat, I am serious and I will report to the principal. Please make sure that if you tell me the content of the testing material, you will be considered favorably.

Yours sincerely,
