你从某英语报纸上看到中美交流活动招聘中学生志愿者，主要负责叫美国中学生汉语。用英语说明为什么要当志愿 。100字

Dear Sir,
I learned from the XX Enlish newspaper that you need middle school students to work as volunteers, whose major work is to teach American students Chinese.
I want to apply for the post because I think I am qualified to do the job.I am a senior middle school student. I am good at Chinese and English both in speaking and in writing.What's more, the most attractive thing for me is that I can practice my English with native speakers through the work.I will be very active to do it. It is really an exciting task for me. Besides, I can contribute to making the people in the US and China communicate with each other more.It is a great honor for me.
I am looking forward to your reply,and I am well prepared for it.
yours sincerely,
