                                                            Table manners in America

    Don't circle your plate with your arms. If you do so, you will become the focus  (焦点)  of the table.

Everyone would wonder, "Is there anything wrong with the food?" This may give a wrong message that

you don't like the food or something like that.

    Don't push the plate back when finished. Leave it where it was. Do you want to let the hostess (女主人)know that you've just done a labour?                                    

    Don't lean (倚靠) back and say "I'm through" or "I'm full". Just put the fork and knife across the plate.

That's all.

    Don't cut up everything before you start to eat. Cut only one or two bites (块) at a time. Never take

a huge mouthful of anything. Do you want to show how hungry you are? Don't do that. It's not so good.

    It's never good to reach across the table for anything. If the thing you want is not at hand, simply ask

the nearest person for help, like "Mrs. Smith, could you pass me the dish?"
