Dear Miss Zhao
I would like to say"Thank you"most . I can never pay you back for your kindness and your patience. I used to be weak in English. You found my problem and talked about how to learn English well with me. You helped a lot with my English after school.It was you who helped me out. I still remember your smile on the day when I got a high mark in English finally exam. It was you who gave me the confidence and made me be interested in English. Hope you will be healthy and young forever.
Yours
