主题:介绍自己特长/强项
Dear Sir,
I want to join your organization (组织) to help kids with sports, music and English.
My name is Mike. I am 15 years old. I'm a student in No. 1 Middle school. I can play the guitar well. I can sing many songs. I can swim and speak English well, too. I think I can be good with the kids. I also do well in telling stories.
I hope to get your letter soon.
Yours,
Mike
