English composition, if you are Li Hua, you study in an all-English middle school, and your music teacher, mrgree.

I am writing this letter to express my sincere thanks for your help in the singing contest held last week.

Thanks to your guidance, I won the first place in the competition. In my opinion, you helped me choose the song that suits me best. Besides, you gave me some valuable advice on how to sing well. Whenever I make a mistake, you always patiently point it out and help me correct it. With your sincere and selfless help, I made rapid progress, and our efforts finally paid off.

Dear Mr. Green, I thank you again.

yours respectfully/sincerely

Li Hua
