假定你是李华。请你给笔友 Peter 写封信，告诉他你叔叔李明将去他所在城市开会，带去他想要的那幅中国画，同时询问他是否可以接机。信中还需说明：
How are you doing？I m writing to tell you that my uncle LiMing is going to have a meeting in your city. Do you remember the Chinese painting I promised you last year? My uncle will bring it to you soon. I hope you will like it.
I wonder if you could do me a favor. This is the first time that my uncle visits the US, so I hope you can meet him at the airport. He arrives at 11 ：30 a.m on August 6th and his flight number is CA 985. I would appreciate it if you could take him to his hotel. My uncle is tall. He will be wearing dark glasses and a blue jacket.
Looking forward to your reply.
