| Dear Nancy, Thanks for your message. Yes, I'm having a great time on my exchange program in France. It's even better than I thought it would be. I was 1 nervous before I arrived here, but there was 2 reason to be. My host family is really nice. They 3 to make me feel at home. And you wouldn't believe how quickly my French has improved! I'm very comfortable speaking French now. My biggest challenge is learning how to behave at the dinner table. As you 4 imagine, things are really different from the way they are at home. For example, you shouldn't put your bread on your plate. You 5 it on the table! I thought that was pretty strange at first, 6 now I'm used to it. You shouldn't eat anything with your hands 7 bread, not even fruit! (You have to cut it up and eat it with a fork. ) Another thing is that it is very 8 to say you're full. If you don't want any more food, you should just say,"It was delicious." Also, it's not polite to put your hands in your lap.. You should always keep your hands, but not your elbows, on the table. I have to say, I find 9 difficult to remember everything, but I'm gradually getting used to things, and don't find them so strange any more. I'll write soon and tell you more about life in France. Hope 10 a good school year. Wang Kun | |||
