2。1 Definitions of Idioms   

Broadly speaking Chinese idioms and English idioms to some extent are roughly the same。 Idiom in Chinese language is also known as“习语”, and it is one of the vital part of the vocabulary system。 It may cover the fixed combinations of words, including idioms, proverbs, maxims, twisters, and so on。 Its main characteristic is the integrity of quality and semantic structures, which are fixed in the long term use。 文献综述

English idioms have a very broad meaning。 According to Oxford Advanced English (the fourth edition), an idiom is a phrase or sentence whose meaning is not clear from the meaning of its inpidual words and it must be known as a whole unit。 English idiom is a relatively standard spoken and written English today, and it is a highly developed language。 The definition of idiom, given by the Oxford English Dictionary, is that a peculiarity of phraseology approved by the usage of language and often has a special signification other than its grammatical or logical one。(Clitra Femand 1996) 

In reference to the definition of idiom, some other people also show their opinions。 Logan Pear Smith defines idioms as the“words, idioms, and phrase, which transgress either the laws of grammar or the laws of logic。” (L。P。Smith 2005) 

Another definition given by Long man’s English idiom Dictionary is “a fixed phrase, which has a peculiar meaning, and the meaning is not the total collection of every singular meaning of the word。”(Collins Cobuild 2000) 

Everything is changing in every minute and there is no exception for English idioms。 With the development of  culture and language itself, the meaning of English idioms is also changing It’s not only the simple illustration of each word。 It’s the combination of a country’s culture, life and the background of society。 The meanings of most idioms are complex and difficult to handle。 That is because the idiom has its own idiom system, and idiom has its own scope, and it is widely recognized that the idiom  includes slang, proverb, allusions, similes, metaphors and collocations。（Chen, 2008:3-4）
