3. 参考词汇： 学生会 Student Union
Dear Carl, ____________________________________________________________________________________________________________________________________________________________________________________________________________
How is your trip in my city? On behalf of the Student Union in my school, I’m writing to invite you to give us a talk from 3 p.m. to 5 a.m. next Wednesday.
I wonder if you can give us some advice on how to learn English, especially oral English in a more effective way. Also, we are interested in what American students do in daily lives. In addition, some differences between China and America from your experiences will be welcome.
Is the time convenient for you? If not, can you suggest another time? I would be more than happy if you could give me an early reply. Wish you a happy holiday in China.
