The Relationship between Clause Complexes and Rhetorical Moves in Academic Papers’ Introductions—A Comparative Study between L1 and L2

学术论文中语言形式和修辞功能的关系是一个热点话题，小句复合体和修辞功能的关系值得研究。本文以100篇理工科英文学术论文引言部分为研究对象，根据Halliday对小句复合体的分类以及Swales CARS模型中的语步结构，探究本族语者(L1)和中国博士生(L2)使用小句复合体实现不同语步的修辞功能的异同。研究结果表明二者在引言写作时使用不同的小句复合体实现特定的修辞功能，且在使用类型与频次上存在显著差异，差异主要体现在语步一和语步三。本研究可以促进二语写作教学。The relationship between linguistic forms and rhetorical functions in academic papers is a hot topic. The relationship between clause complexes and rhetorical functions merits investigation. This study takes the introduction sections of 100 English academic papers in science and engineering as the research object. Based on Halliday’s classification of clause complexes and the move structure in Swales’ CARS model, it explores the similarities and differences in how native speakers (L1) and Chinese doctoral students (L2) use clause complexes to achieve the rhetorical functions of different moves. The results show that L1 and L2 use different clause complexes to achieve specific rhetorical functions in introduction writing, and there are significant differences in the types and frequencies of clause complexes in Move 1 and Move 3. This study can promote second language writing pedagogy.
