Abstract：The lexical chunk is a kind of lexicalized collection, which includes words, phrases, grammars and pragmatics. The aim of lexical chunk studying is to aid English learners to communicate by using chunks. After they have noticed the meaning of vocabulary in the sense of context, pragmatics and text through the teacher’s guidance, the English learners will combine the vocabulary learning with the grammars learning together. It not only helps learners to memorize the language, but also encourages them to use the language creatively. Lexical chunk learning outweighs other learning methods in the area of listening, speaking, writing learning etc. With its unique advantage, the lexical chunk has been a new trend in English language learning. I manage to analyze the functions of lexical chunks on the English learning, especially on the listening learning, speaking learning and writing learning. After analyzing the functions, I will discuss how to use the lexical chunks in real learning and teaching. I also observe the current teaching situation, seek some problems and raise some methods to solve these problems. What’s more, my purpose is to complete the function of lexical chunks on English learning and promote the reform of English teaching.

摘要：语块是一类词汇的集合，包括单词，短语，语法和语用学。语块学习的目的是帮助英语学习者能够利用语块交流。在他们通过教师的指导，注意到词汇在一定语境，语用和篇章中的意义后，英语学习者们便将会把词汇学习与语法学习相结合。这不仅仅帮助学习者们记忆语言点，而且激励他们创造性的运用语言。语块学习与其他学习方法相比较，在听，说，写等领域也占有极为重要的地位。由于它独特的优势，语块在英语语言的学习中已成为一种新的趋势。笔者试图将语块理论在英语学习各方面的作用进行分析，具体为语块在听力、口语和写作中的作用，并在分析作用的基础上，讨论如何真正的将语块落实到英语学习及教学中，结合现状发现问题，提出解决问题的方法，进而完善语块理论在英语学习中的运用，推进英语教学的改革。

　　　In tradition, when talking about vocabulary learning, it usually refers to dealing with the vocabulary in grammatical conception, which is quite abstract. It seldom considers putting vocabulary learning into practice in real language environment. However, the form and the meaning of the vocabulary are relevant. The syntax and the vocabulary are also relevant. These characteristics are reflected in colligation and collocation. Based on these characteristics, the conception of lexical chunk is put forward.
