                                                        "Thank you" and "Excuse me"

    American people have the habbit of saying "Thank you". They say "Thank you" whenever others help

them or say something kind to them. People of other countries do so, too. You should say "Thank you"

when someone passes you the salt on the table, when someone walking ahead of you keeps the door open

for you, or when someone says your work is well done, or you have bought a nice thing, or your city is

beautiful.

    "Thank you" is used not only between friends, but also between parents and children, brothers and

sisters, husbands and wives.

    "Excuse me" is another short sentence they use. when you hear someone say so behind you, you know

that somebody wants to walk past without touching (触及) you.

    It's not polite to break others while they are talking. If you want to speak to one of them, say "Excuse

me" first, and then begin talking. You should also do so when you want to cough or make any unpleasant

noise before others.

    There are many occasions for "Thank you" and "Excuse me". We should learn to say them in the right

situation.

根据短文内容,判断下列句子的正(A)误(B)。

( )1. If you someone says you speak very good English, you should say "Thank you".

( )2. If you want to disturb (打扰) the people who are talking, begin with "Excuse me".

( )3. You needn't say "Excuse me" when you want to cough or make any unpleasant noise before others.
