1. Introduction

As we all know， language is closely related to culture. Every language is part of a culture. Idioms as a special form of language exist in both language and culture and carry a large amount of cultural information such as histories， geography， religions， customs， nationality psychology， thought pattern etc， and therefore are closely related to culture.

2. The characteristics of idioms

An idiom is a fixed group of words with a special different meaning from the meanings of the separate words. Idioms consist of set phrases and short sentences， they are expressions that are not readily understandable from their literal meaning of individual elements. The practicality of idioms is the longtime vitality of idioms. According to the linguists， the number of the English idioms is about 50000. In modern English， there are about 4000 used often. And there are about 5000 idioms more often used. That is why English idiom is an indispensable part of English lexis. We can say that English idioms are used more widely and often than Chinese idioms.

The unitary meaning of idioms means that we must see the idioms as a unit. The meaning of idioms isnt the simple mixture of the each words meaning， but it has its own new meaning.（汪榕培， 盧曉娟， 1997：373） And if you break up each word that form the idiom， though you can see the meaning of each word， you cant see the meaning of this idiom. For example， Im under the weather. “Under the weather” means unwell and unhappy.（Claire， 1991：175） If you see the meaning from each word， its meaningless.

The syntactic frozenness of the idioms means that we cant add or reduce one word of the idioms， because it may change its original meaning. （汪榕培， 盧曉娟，1997：375） For instance， we cant change “under the weather” into “below the weather”. We cant change “to have an axe to grind” into “to have a chopper to grind” or “to have a hatchet to grind”.

3. The origin of idioms

American and Britain are the countries that have Christianity and Hebraism as their cultural background. Most idioms produced in this background carry rich religious elements.（平洪，張國(guó)揚(yáng)，2000：85）Getting to the roots of the idioms， we can find that they originated from literary masterpieces， the Bible， Greek and Roman mythologies， ancient fables， historical events， anecdotes， customs， seafaring， daily life and so on， which involve every aspect of life.（莊和誠(chéng)，2002：185） Thats why idioms are hard to understand. The essential of studying idioms is grasping idioms through the background of the traditional culture， thought patterns， geographies， religions and the customs.Idioms originate from many aspects. They originate from ancient fables， historical affairs， anecdotes， customs， animals habitual behaviors， peoples daily life and so on.

From the sources of the idioms， we can see that idiom originates from western cultural background.

Observing the hidden meaning of the idioms， we can feel the national value.

4. Conclusion

As such， it cannot but serve and reflect culture needs. Idiom closely relates to the culture. Idiom today is highly used in the daily life.
