Dear Mr. Li,
I am very excited to write and express my thanks to you.
I am now a freshman in Wuhan University, which is what I have been dreaming of. Mr. Li, I still remember the days when you taught me English. Thanks to your creative work, I have made great progress in my English. However, there was a time when the pressure of exams, too much homework and high expectations let me down. I was tired of being warned that if I didn't do my best, I wouldn't have a chance to go to college. Thank you for your encouragement; If not, I won't achieve my dream. Now I really understand you. I hope more and more students can enter their ideal universities. Are you still so busy? How I miss you!
I look forward to hearing from you soon.
your
