Suppose your foreign teacher Bill announced at your classroom that he’s got four extra tickets for the coming Irish Tap Dance at the Science and Art Center, and that students who are interested in watching it should write to him and tell him the reasons. You are now writing to Bill to express your willingness to watch the dance.
You should write approximately 100 words. Do not sign your own name at the end of your letter. Use "Zhang Hua" instead. You do not need to write the address.
