摘要

语块是近年来语言研究的重要课题。各界学者分别从认知语言学、应用语言学、心理语言学、跨文化交际学等不同研究领域对语块进行了不同研究并得出一定成果。这些成果从听力、阅读等各个方面加深了国内语言学习者和研究者对语块的认识，促进英语研究的发展。本文则试图从写作方面对语块进行研究。
本文试图找出短语使用情况与其分数高低的关系，从而为英语语块的学习与教学提供建议。本论文主要运用定量研究法与方差分析法。本文通过资料搜集与分析，明确了语块的定义与分类，确定了研究方法，为下一部研究打好基础。此外，本文从大学四级英语考试答卷中选取了300篇作文，并对每篇作文中短语语块的使用情况进行了分析与研究。本文尝试通过相关数据分析找到短语语块的使用与其作文得分的相关性。
通过分析与研究, 本文发现语块的使用确实与其得分存在相关性。使用率和正确使用率的高低影响着作文得分的高低；而不同分数段的作文对语块使用情况与掌握情况又不尽相同。基于以上研究结论，本论文试图为英语学习者、教学者与研究者提供建议。

Abstract

In recent years, lexical chunk has been a main subject of language researches. Scholars from various fields have done a lot of researches from different perspectives, such as cognitive linguistics, applied linguistics, psycholinguistics and cross-cultural communication and so on. Their achievements, from aspects of listening, reading and so on, have deepened the recognition of lexical chunks of domestic language learners and researchers, and they also contribute to the development of English studying. This paper attempts to do research on lexical chunks from the aspect of writing.
This paper tries to find the correlation effect between the utilization of lexical chunks and their scores of writing, which could provide suggestions for the teaching and learning of lexical chunks. Quantitative approach and ANOVA approach are employed in this paper. By the collecting and analyzing of materials, this paper defines and classifies lexical chunks, which do a great favor to further study. Besides, 300 pieces of writing paper are chosen from the CET-4 test held last December. This paper tries to find the correlation between the utilization of lexical chunks and the scores by doing relevant data analysis.
Though analyzing and studying, this paper finds that there exists some correlation between the using of lexical chunks and its scores. The utilization rate and the correct utilization rate will affect the score of writing; and different level of scores master different kinds of lexical chunks. Based on the above findings, this paper attempts to give suggestions for English learners, teachers and researchers.
