假如你的朋友李明去参加美国朋友的家庭宴会，他不懂如何应付，希望你给他提出建议，告诉他怎么做。 内容

If you want to make a good impression at an American dinner party, you may do as follows: First of all, you should buy a small gift,such as a bottle of wine or a box of chocolate for your host or hostess. Second, arrive on time. You may arrive about ten minutes earlier. Third, during the dinner, don’t forget to say that the food is delicious. After you finish eating, you shouldn’t stay too long. Finally, thank your host or hostess for the good dinner when you leave.

可以找人练习练习，也可以找专业人士来教，望采纳。
