I am writing to thank you for your hard work for me. With your help, I make great progress in my study. A year ago, my study was bad and I didn’t want to learn, but you never give me up. You told me that I was clever. As long as I work hard, I would be great. In this year, you cared much about my study and helped me a lot. When I made mistakes, you always pointed them out and helped me to correct. Now, my study is much better than before, and I want to express my gratitude to you. Hope you everything goes well.
Sincerely yours,
