     If you can speak English, you know a lot of English words. You can read, speak and understand.

But there is another kind of language you need to know — the language of the body.

     All over the world, people "talk" with their hands, with their heads and with their eyes. When

Japanese people meet, they bow. When Indians meet, they put their hands together. What do

Americans and British people do?

     Americans are more informal (不拘礼节的) than the British. They like to be friendly. They use

first names, ask questions and talk easily about themselves. When they sit down, they like to relax in

their chairs and make themselves comfortable.

     British people are more reserved (矜持的). They take more time to make friends. They like to

know you before they ask you something of your home.

     When British and American people meet someone for the first time, they shake hands. They do

not usually shake hands with people they know well. Women sometimes kiss their women friends,

and men kiss women friends. When a man meets a man friend, he just smiles, and says "Hello". Men

do not kiss each other or hold hands. Even fathers and sons do not often kiss each other.
