dear Miss Yao,
as the gratuation is driving near,I feel more grateful for you.In the past three year,you teach me a lot.Your encouragement really help me make progress.

I think you're almost perfrct except to be a little serious.If you could have more smile in the class.that would be better.
All in all,thanks for all the help you give me in the past three years.Best wishes!
