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。
Using the SFL context language model as a guide to explore the meaning occurrence patterns of academic abstracts can effectively circumvent the limitations of the existing research in the “step by step ” structure, from the discourse community “cultural convention ” perspective The lack of surface description. The research found that the abstracts of academic dissertations belong to macro propositional discourse, and their taxonomic structures are “schematized” tendencies, followed by “introducing research background”, “summarizing research process”, “expatiating the meaning of research” The three phases constitute the importance, scientificity and value of the research, driven by the rhetoric motivation of establishing the research rationale, showing the research letter / validity and affirming the research value respectively. This study has important implications for the study of academic discourse and academic reading and writing teaching.
