Dear John,

尊敬的John：，

I know that you will visit your Chinese teacher's home. If you do the following, I don't think you will feel uncomfortable.

我知道你会去你的语文老师家。如果这样做，我觉得你会比较舒服。

First, you should arrive a little earlier. Being late is impolite. Second, it's also good to bring a gift such as some flowers or fruit. Third, you will use chopsticks to have dinner. Remember not to stick your chopsticks into your food. You'd better say that the food is delicious while you are eating. Finally, after dinner, showing thanks is also necessary. And you are not supposed to stay long after dinner.

首先，你应该早点到。迟到是不礼貌的。第二，带些鲜花或水果之类的礼物也是不错的。第三，要用筷子吃饭。记住不要把筷子插进食物里。你最好在吃饭的时候说食物很好吃。最后，晚餐后，表示感谢也是必要的。晚饭后不要呆太久。

Good luck!

祝你好运

Yours,Bob

你的 Bob
