【思路点拨】本文是一篇书信,要求向美国朋友介绍来中国度假时需要注意的一些礼仪习俗。写作时,首先应对朋友的到来表示欢迎。然后按照提示内容以礼貌的语气清晰地介绍需要重点注意的礼仪习俗,提醒朋友中美之间的礼仪差异。写作时可能用到的句型有“be supposed to ...”“be expected to ...”“It's + 形容词 + to do sth. ”等。
【范文示例】
Dear Ben,
I'm glad you'll come to China for your holiday. Let me tell you some customs here.
When you meet someone for the first time here, you are supposed to shake hands. And you're supposed to knock at the door before you go into others' houses. You are not supposed to talk loudly in public places. If you are invited to a friend's home for dinner, you should arrive on time. And you'd better take a present, but it's not necessary to buy an expensive one.
Yours,
Li Hua
