假设你是李华，你的美国朋友Tim作为交换生将来中国学习一年。于是，你写信邀请他有时间来你家做客，

Tim,

I've heard that you will come to China for exchanging learning program and stay in for about 1 year. I'm so glad on this news, and also hope that you can visit my home then. And of course I will treat you with tons of delicious Chinese food! By the way, could you bring me an English novel named "Tuesday with Morrie"? I like it but I can't find it in China. I will be very appreciate for your favor.

Hope to see you soon!

Sincerely
你稍微改改就行。

你有病
