Dear Mr. Lai,

　　尊敬的賴老師：

　　I am writing this letter just want to say thanks to you. I am going to graduate in two weeks. You have been my class adviser for three years. During these three years you have spent lots of energy on us. You are not only teaching knowledge in the class, but also care our life. Sometimes we are afraid of you, because of your strict requirement for our study. However, you are so helpful in the daily life. No matter what difficulties we are in, you will help if you can. So, I also want to say sorry to you for making so much trouble. But you bear all my trouble. I don’t know what kind of class adviser I will meet in the future study, but I will remember and appreciate you forever. I want to say thank you again.

　　我寫這封信只是想跟你說聲謝謝。還有兩周我就要畢業了。你做了我三年的班主任。在這三年你花了那么多精力在我們身上。你不僅僅在課堂上傳授我們知識，而且在生活上也很關心我們。不過有時候我們有點怕你，因為你對我們學習的嚴格要求。不過，在日常生活中你是那么的樂于助人。無論我們遇到什么樣的困難，只要能夠幫得上忙你都會幫我們。所以，我還想對你說聲對不起，給你帶來那么多的麻煩。但是你都一一包容了。我不知道我會在今后的學習中遇到什么樣的班主任，但是我會一直記得你、感激你的。我想再次說聲謝謝。
