 (1992:1)  use lexical phrases to describe and define them as a lexical phenomenon which different from the traditional vocabulary and syntax. The lexical phrases are a combination of function  and  form.  They  are  commonly  used  in  the  use  of  language  than  the  general rules  of  grammar,  and  they  have  more  clear  meaning.  They  ranged  in  length,  but regardless of length, there is a relative stable form with selectivity. The chunk has its own  functions  in  pragmatic.  Yao  Baoliang  (2003:23)  holds  that  lexical  chunks  are different from general phrases, and they are a kind of linguistic unit with both lexical and  grammatical  features.  Yan  Xianbao  (2009:2)  believes  that  lexical  chunks  are present in the human brain memory bank in the form of fixed or semi-fixed structures.

2.2 Classifications of lexical chunks 
The  most  common  and  widely  accepted  classification  of  lexical  chunks  is Michael Lewis and Nattinger & De Carrico’s classification.Michael  Lewis  (1997:255-270)  divides  the  lexical  chunks  into  four  types  based on the syntactic functions and semantic relations: (1) Words & poly-words: which are the traditional term, the former refers to the traditional meaning of the word, the latter refers to over one word by a fixed phrase or clauses, the word can not be replaced, for example: “in my opinion”, “as long as” can not be replaced by “on my opinion”, “as longer as”. (2) Collocations: means a higher frequency of word combinations, such as verb + noun (put up your hands), adjective + noun (a beautiful girl), is a kind of relationship between  words  in  the  long  term.  This  relationship  is  a  kind  of  structure  that  can predict each other’s partner, such as suicide must match with commit. To understand these collocations is the basis for forming accurate and natural expressions of English. (3)  Institutionalized  expression:  indicates  a  fixed  or  semi-fixed  word  that combined  with  confirmed  pragmatic  functions,  which  are  the  complete  sentences  or fixed at the beginning of the sentence, such as “If I were you…”, “I’ m afraid…”, and “How  are  you”?  The  institutionalized  expressions  are  mainly  refers  to  spoken language.
