1.2 Research Significance 
The lexical chunk approach and vocabulary learning can be combined in the process of a foreign language learning, especially at the very beginning stage. The effects of lexical chunk of English vocabulary teaching are described as follows. Based  on  the  lexical  chunk  teaching  approach,  the  encoding  system  of  English vocabulary can establish the connection of one word with another word, which shares similar concepts. Lexical chunk can not only enhance their memorization of words but also improve their  word  extraction  abilities.  That  is  to  say,  it  makes  it  possible  that  students  can  create fluent English expressions timely when they have the need to extract the words from memory. Meanwhile,  the  encoding  system  memory  of  lexical  chunks  can  avoid  the  vapidity  and inefficiency of mechanical memory. It  is  difficult  for  students  to  transmit  information  in  English.  However,  such  kind  of problems can be perfectly solved by learning abundant lexical chunks. When a large quantity of  lexical  chunks  are  stored  in  students’  mind,  they  can  easily  express  themselves  which makes them feel good and greatly mobilize the enthusiasm for foreign language acquisition. Due  to  the  specific  pragmatic  functions  of  lexical  chunks,  students  can  communicate  with people fluently when they memorize the lexical chunks, and they naturally have a great sense of satisfaction, which will mobilize their enthusiasm for vocabulary learning greatly.

Chapter Two   Literature Review 

Since 1990, a lot of researches on English vocabulary teaching and learning have been done by various experts and scholars at home and abroad. This kind of research takes notice of  all  the  five  parts  of  learning  language,  namely  listening,  speaking,  reading,  writing  and translation. In this chapter, some related studies on English vocabulary teaching both at home and  abroad  will  be  mainly  introduced  by  the  author,  including  their  ideas  and  famous representatives.

2.1 Definition of Lexical Chunk
Vocabularies  are  divided  into  two  parts  by  conventional  linguistics,  that  is,  free combination of words that can be explained by grammatical rules and fixed phrase which can not  be  explained  by  the  grammar  rules.  Because  English  words  are  regular,  productive composite  units,  while  fixed  phrases  are  non-biodegrdable,  degraded  and  independent language units. Chunk is the main form of human cognition: it grows by putting a number of already  formed  chunks  together  in  memory  and  then  combining  them  into  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。
