语义场视域下语篇主位结构之研究

A study on thematic structure of texts from the view of semantic field

把主位结构作为功能语篇分析的重要手段,对具体语篇进行主位分析,并利用语义场理论去解读语篇句际间的语义联系是如何通过主位推进模式进行建构的。研究表明,语义场理论发掘了主位结构的语义内涵,使研究的范围从词汇层面经由小句层面扩展到篇章层面,从而更有效地指导功能语篇分析。

This paper attempts to take thematic structure as an important means of functional text analysis to have a thematic analysis on a specific text firstly,and then with the theory of semantic field,it attempts to interpret an issue that how are the semantic relations among clauses constructed by thematic progression.The study indicates that semantic field as a theoretical basis can explore thematic structure a semantic connotation,so that the research scope can go through three layers：word layers,clause layers and text layer,which can promote effective functional text analysis,guarantee the coherence and integrality of texts,as well as the consistency and coordination of semantic meaning.
