Dear_______, (裡面填老師姓氏的拼音,如果是男老師姓氏前面就寫Mr.,女老師的話姓氏前面寫Ms.,名字後面寫冒號不要寫逗號) it's almost time for us to graduate. Thank you for teaching us for this past tow years. You always taught us how to be a better person; though it seems to you that I didn't really care about this matter, I think of your teachings more often as graduation approaches.
I sometimes make mistakes that make you so mad, but as a matter of fact, I appreciate you very much. Graduation is just around the corner now, and the time we can spend together is getting shorter... But I plan to end with a good performance. Even after graduation, I will think of you a lot. Thank you Mr./Ms.________ (一樣填老師的姓氏) Yours truly, __________(自己的名字,靠右對齊)
