Abstract:  With the rapid development of the corpus linguistics and the cognitive linguistics, people’s understanding of chunks has shifted from the theoretical level to the practical level. Therefore, much attention has been paid to chunks and their status in second language acquisition and application has been improved. Just as the foreign linguists use different terms to call chunks, different linguists give different definition and criteria to categorization of chunks, but their divergence does not influence the important role chunks play in second language acquisition and foreign language teaching. This paper, under the instruction of the lexical chunk theory, by means of questionnaires and data analysis, studies the problems in the English writing teaching in Chinese senior high schools. Combining with the benefits of chunks in second language acquisition and foreign language teaching as well as the lexical approach proposed by Lewis（1993）, this paper gives some suggestions to improving the proficiency and competence of Chinese senior high school students.

摘要: 随着语料库语言学和认知语言学的迅速发展，人们对语块的认识经历了一个从理论到实践的认识过程。语块的作用越来越受到重视，在语言习得与应用中的地位也相应提高。语块通常作为一个整体储存在记忆中，使用时直接提取，无需根据语块规则生成和分析。由于国外语言学家并未使用统一的名词称呼语块，不同的语言学家对其定义与分类也不尽相同。但这并不影响语块在二语习得及外语教学中的重要作用。本文在语块理论的指导下，通过问卷调查和数据分析的方法，从高中英语写作教学着手，对高中英语写作中存在的问题进行研究， 并结合语块在二语习得及外语教学中的作用和Lewis的语块教学法，找出切实可行的解决办法，提高高中学生的英语写作水平与能力。
