                                               The way we do things round here

    Some years ago, I was hired by an American bank.I received a letter from the head of the Personnel

Department that started, "Dear John, I am quite pleased that you have decided to join us." That "quite"

saddened me.I thought he was saying "we're kind of pleased you decided to join us although I wish we

had hired someone else." Then I discovered that in American English "quite" sometimes means "very",

while in British English it means "fairly".

    So the first lesson about working in other countries is to learn the language and by that I don't just

mean the words people speak.It is body language, dress, manners, ideas and so on.The way people do

things highlights many of the differences we see between cultures (文化).

Some of these differences may be only on the surface-dress, food and hours of work-while others may

be deeper and take longer to deal with.Mostly, it is just a question of getting used to the differences and

accepting them, like the climate (气候), while getting on with business.

     Some of the differences may be an improvement.People are more polite; the service is better;you

ask for something to be done and it happens without having to ask again.However, other differences can

be troubling, like punctuality (准时). If you invite people to a party at 7 o'clock your guests will consider

it polite to turn up exactly on time in Germany, five minutes early in the American Midwest, an hour early

in Japan, 15 minutes afterwards in the UK, up to an hour afterwards in Italy and some time in the

evening in Greece.I prefer not to use the word "late" because there is nothing wrong with the times

people arrive.It is simply the accepted thing to do in their own country.

1. The author was unhappy as mentioned in Paragraph 1 because he thought________.

A. the American bank didn't think much of him

B. the American bank might hire another person

C. it's difficult to get used to American culture

D. it's easy to misunderstand Americans

2. The word "highlights" in Paragraph 2 probably means______.

A. encourages 

B. helps to narrow

C. increases  

D. draws attention to

3. According to the author, what should we do with most cultural differences?

A. Ask the native people for help.

B. Understand and accept them.

C. Do things in our own way.

D. Do indepth research.

4. When invited to a party the people who are usually punctual are________.

A. Italians  

B. Germans

C. Greeks  

D. the British
