参考范文

May I have your attention, please?

     As you know, our class will have a talk show on environment protection with Class One on May 4th.Before it takes place, we will invite Dr Li from Qinghua University to give us a talk on the environment problem and he will also tell us about the improvement in environment protection in recent years in Beijing.

     The report will begin at 2:00 pm on Wednesday, April 30th in the auditorium on the third floor in the classroom building. I’m sure we can get enough information from his talk to make good preparations for the coming talk show. everyone should be there on time, then listen to the report and make full notes at the same time.

     By the way, we will have a discussion after the report.

     That’s all. Thank you.
