【正确答案】Attention please, everyone:
About 20 American students will come to our school for a visit on September 15th. We will meet at school gate at 8:45 a.m., and give them a warm welcome when they arrive at 9 a.m. Then we'll take them to the reception room. After a welcome party there, we'll show them around the school, the library, the teaching building, and the training building. At 11:30, we'll have lunch with the American students in the canteen, and then give the presents to each other. The American students will leave at about 12:00. That's all.
Thank you.
