May I have your attention, please?

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

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

That’s all. Thank you.
