假如你是李华，你的英国朋友汤姆计划春节的时候来中国旅游，希望你做他的向导，当你因为学校交流项目要去澳大利亚而无法陪他，写信向他抱歉，并推荐你的同学李雷做他的导游

Dear Tom,

Thank you for your letter. I am glad that you want me to be your guide in China. Unfortunately, our school organized an exchange program to Australia and I have already agreed to attend this program. As a result, I will not be in China during Spring Festival and are not able to show you around. I am sorry about that. However, I would like to recommand my classmate Li Lei to you. He is such a good person and you can trust him to be your guide.

Yours,
Li Hua
