摘要句法复杂性 (syntactic complexity), 又称句法成熟度 (syntactic maturity), 体现的是句子的多变性和内部结构的复杂程度, 因此可以作为衡量英语写作水平的重要标准。 本研究从南京理工大学的一次 “外研社杯” 全国英语写作大赛选拔赛中抽取25篇高分作文和25篇低分作文, 从总体复杂性, 从属复杂性, 和句子复杂性三方面来分析其句法复杂性, 旨在探讨不同英语水平学生议论文写作中的句法复杂性差异。 研究结果表明， 在总体复杂性和句子复杂性方面， 高英语水平学生写作总体表现要优于低英语水平学生写作； 然而在从属复杂性方面， 两者表现差异不大。30997

Title A Study on the Syntactic Complexity of Argumentative Compositions by College Students of Different English Levels
Abstract
Syntactic complexity reflects the variety of language production forms and sophistication of the internal structure of sentences, as a result, it can be used to assess writing levels of English learners. In this study, 50 writings were selected from a qualification contest of “FLTRP Cup” English writing contest in Nanjing University of Science and Technology, 25 writings from higher performance group and 25 writings from low performance group; Three indices from overall complexity, subordination complexity and phrasal complexity were employed. This study is aimed at finding the difference of syntactic complexity between students with different English levels. Results showed that in overall complexity and phrasal complexity, the writings of students with higher English level perform better than those of students with lower English level; However, in subordination complexity, there is no big difference between the two groups.

1 Introduction
1.1 Background
Writing is considered as one of the most crucial ways to measure English language learner’s proficiency, for it is an important language output. However, during real English teaching process, writing has been proved to be a weak link among college students. For many years, researchers have been studying second language writing in order to find the problems causing this phenomenon and work out effective ways to improve second language learner’s performance in English writing.
