     阅读下面的短文,并根据短文后的要求答题。(请注意问题后的字数要求)。

     Just like the United States,Britain is divided into different areas. Britain is one of the most

diverse nations in Europe with over 250 different languages being spoken in London alone.

With such a various culture,adapting to it can be a challenge for anyone. Following these steps

should be of great help to you.

     Forget the stereotypes (成见). Many of the long formed stereotypes simply have nothing

to do with Britain today. Don't think that everyone enjoys drinking tea or beer. Abandoning some

old ideas of people and culture will allow you to be more open-minded and easily get into the culture.

     Understand the differences. Britain is made up of different areas that have their different

traditions and languages. Understanding different cultures will help you avoid making mistakes.

     Get used to small spaces. The US is a huge country where people are used to bigger cars,

houses and spaces.__________, Britain does not have the luxury of space. Houses,apartments

and cars are all smaller than you are used to,so trying to become familiar with smaller areas is very

necessary.

     Be polite. Always apologize for knocking into someone, even if it was their fault. Respect

people's personal space and always wait in line. Bill Brysons' book Notes from a small island is

filled with many useful tips.

     Accept the jokes. One of the most confusing aspects of British culture is humor. Kidding,

teasing,or "taking the mick" are all ways to describe making fun of someone but this isn't necessarily

a bad thing. Playing tricks on someone is a common way to show affection. As Britons usually put

it,"you never make fun of someone you don't like".
