假如你是李华，你所在的学校即将迎接一个美国学生交流团，请你用英语就此给广播站写个通讯稿，内容主要包

Dear students.

There is a good news for all of us. An American exchange group is going to visit us soon. In order to leave them a good impression, we are suggested to do the following things.
Firstly, I hope that we can give the American students warm welcome.
Secondly, please be aware that American culture is different from Chinese culture. The American students might be very outgoing and they are not as modest as us.
Thirdly, we need to be polite to the American students. For example, when you meet them at school, please say “Hello”or just smile to them.
You can take this chance to make some foreign friends too.

望采纳。
