Boys and girls,

    May I have your attention, please?

    There will a lecture in our library, at 4:00 on Wednesday afternoon. We are very honour to have invited Professor Tang Wenfang, who has been studied cultural differences in Tsinghua University for many years, in talk about the differences between American and Chinese cultures, that may be quite an interested topic. After a lecture, you are welcome to share your experience in China with everyone else present. Since you have stayed in China for half a year, because you have anything that what puzzles you, it would be great to talk with Mr.Tang. He will be glad to communicate with you. Please be present on time.

    That's all. Thank you.
