【感谢信高中英语作文】Dear Mr. Li,

I am writing this letter to express my sincere gratitude for your help and support during the past semester. As a high school student, I have always found it difficult to balance my studies with other activities. However, thanks to your guidance, I have been able to improve my academic performance and gain more confidence in myself.

When I was struggling with English, you took the time to stay after class and explain the grammar rules to me in a clear and patient way. Your encouragement made me feel that I could overcome any challenge. Not only did you teach me the language, but you also taught me how to think critically and work hard.

I will never forget the way you treated each of your students with kindness and respect. You are not just a teacher, but also a role model who inspires us to be better people. I hope to one day be as helpful and caring as you are.

Once again, thank you very much for everything you have done for me. I really appreciate your time and effort.

Sincerely,

Li Hua
