     The English, as a race, are very different in many ways from all other nationalities, including their closest

neighbors, the French, the Belgians and the Dutch. It is claimed that living on an island separated from the rest

of Europe has much to do with it. Whatever the reasons are, it may be fairly stated that the Englishman has

developed many attitudes and habits which distinguish him from other nationalities.

     Broadly speaking, the Englishman is a quiet, shy, reserved person who is fully relaxed only among people

he knows well. In the presence of strangers or foreigners he often seems restrained, even embarrassed. You

have only to witness a city train any morning or evening to see the truth of this. Serious-looking businessmen

and women sit reading their newspapers or having a light sleep in a corner, and no one speaks. In fact, to do

so would seem most unusual. An Englishman, pretending to be giving advice to overseas visitors, once

suggested, "On entering a railway carriage, shake hands with all the passengers." Needless to say, he was not

being serious. There is an unwritten but clearly understood code of behavior which, if broken, makes the

person immediately suspected.

     In many parts of the world it is quite normal to show openly extremes of enthusiasm, emotion, excitement,

etc., often accompanied by appropriate gesture. The Englishman is somewhat different. Of course, an

Englishman feels no less deeply than anyone of a different nationality, but he tends to display his feelings far

less. This is reflected in his use of language. Imagine a man commenting on the great beauty of a young girl.

A more emotional man might de- scribe her state "Oh, she is a goddess", whereas an Englishman might just

say "Oh, she's all right." An Englishman who has seen a highly successful and enjoyable film recommends it

to a friend by commenting, "It's not bad you know", or on seeing some very unusual scenery he might convey

(表达) his pleasure by saying," Nice, yes, very nice." The overseas visitor must not be disappointed by this

apparent lack of interest and involvement. Instead, he must realize that "all right," "not bad," and "nice," very

often have the sense of "first-class," "excellent," "beautiful". This unique style of language use is particularly

common in England, and is known as restrained statement.
