Dear Mr. Green,
I'm Gao Hui from Xinhua Middle School. I'm very your project and want to be a volunteer teacher to help the students learn Chinese.
I'm friendly and always ready to help others. I'm good at Chinese. Last year, I won the in the Chinese Speech Competition. Some people think it's difficult to learn Chinese well, but I don't think so. I have many good ways to learn Chinese well, listening to the radio and reading aloud every morning. Also I think learning some popular Chinese songs helps improve quickly. Besides, local people is a fun and useful way to learn Chinese and . If I can get the job, I'm sure I will be a great helper.
Yours,
Gao Hui
