邀请信英语作文范文：
Dear Carl,
I'm glad to hear that you' re enjoying your holiday in my city. On behalf of the Student Union in my school, I invite you to give us a talk from 3 p.m. to 5 p.m. next Wednesday.
Please give us some advice on how to learn English, especially oral English in a more effective way. We're also very interested in what American students do in their daily lives. In addition,you can talk about some differences between China and America from your experiences.
Is the time convenient for you? If not, can you suggest another time? I'm looking forward to hearing from you.
Yours,
Li Hua
