学术论文摘要语类的意义发生模式

On Meaning Patterns of RA Abstracts Genre

以SFL的语境语言模型为指导探索学术论文摘要语类的意义发生模式,可有效规避现有研究局限于"语步"构式、从话语社团"文化规约性"视角对其进行表层描写的不足。研究发现:学术论文摘要属宏观命题性话语,其语类结构呈"纲要式"倾向,依次由"引介研究背景"、"概述研究过程"、"阐述研究意义"三个阶段构成,分别在确立研究理据、展示研究信/效度、肯定研究价值的修辞动机推动下,彰显研究的重要性、科学性和价值。本研究对学术语篇语义研究与学术读写教学有重要的启示意义。

Guided by the context-language mode of SFL, the exploration on the meaning patterns of RA abstracts genre can avoid the insufficiency of the previous study, which was limited to the perspective of ＂cultural norms in discourse community＂ and the analysis unit of ＂Move＂. This study finds that RA abstracts genre belongs to the category of macro-proposition and tends to dem- onstrate a schematic structure. It is composed of three phases ： Introduction of Research Background 〉 Generalization of Research Process 〉 Interpretation of Research Significance. Rhetorically, the schematic structure is motivated to establish research rationale, demonstrate research reliability and validity, and affirm research significance respectively to reveal that the research is important, scientific and significant. The findings have important implications for the research on academic discourse semantics and the teaching of academic reading and writing.
