bsp;In  addition,  different  researchers  use  different  terms  to  refer  to  the  lexical  chunk,  for instance,  speech  formulas  (Peters,  1977),  lexicalized  sentence  stems  (Pawley&Syder,  1983), prefabricated  chunks  (Widdowson,  1989),  formulaic  speech  (Ellis,  1999).  There  are  so  many terminologies, justlike Weinert (1995:182) claims: “while labels vary, it seems that researchers have very much the same phenomenon in mind”. According to certain perspectives of language, different terminologies have been proposed by different researchers to refer to the lexical chunks. The author in  this  thesis  chooses  to  use  the  term  “lexical  chunk”.  The  following  are  some  representative definitions of lexical chunks. Becker  (1974:16)  is  one  of  the  early  init iators  who  put  forward  the concept  of  lexical  chunks, he  points  out  that  as  a special  multi-word  phenomenon,  lexical  chunk  are  existed  in  the  form  of fixed  or  semi-fixed  chunks  and  their  functions  are  just  like  that  of  the  traditional  grammar  and lexis. Becker says that the lexical chunks are existing frameworks, and w e just use them to express our  thoughts  and  ideas, so  it  is  not  necessary  for  us  to  put  our  efforts  in  searching  for  discourse when we want to express something.

2.2 Studies of lexical chunk in writing at Home and Abroad 
In  1950s,  J.R.Firth  advanced  the  notion  of  collocations  and  promoted  the  development  of linguistic  theory  in  this  period.  In  Firth’s  opinion,  we  use  a complete  sentence  to  express  our thoughts and ideas, while the sentences are made up of many fixed collocations. Since then, as one of  the  main  constitutes  of  lexical  chunk,  collocation  has  become  a  widely-used  term  and  being widely discussed. In  his  influent ial  paper  on  the  magical  number  seven,  Miller  (1956:  81-97)  advanced  the  term “chunking”.  As  a  psychologist  in  America,  Miller  points  out  that  even  though  our  immediate memory capacity seems to be lim ited to seven units of information, chunking (or coding single units into large units) greatly expand our capacity.  Hakuta (1974) conducts a study of a five years old Japanese  child who learns English and find out  that  learning  of  lexical  chunks  is companied  with  learning  of  language.  Meanwhile,  he  claims that learning of lexical chunks help learners to generate right sentences.  Bolinger (1976) point本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
