论辩语篇中的言据性策略

Evidential Strategies in Argumentative Discourses

论辩语篇是一种以说理为首要目的、以论证为主要修辞手法、以交互沟通为交际目的的综合性议论语篇。而作为表述命题知识来源及信度的语言表征,言据性编码了说话人/作者对语篇命题的态度评价和介入程度。本文以言据性研究为基础,重新审视知识来源与证素使用之间的语用关联性,通过分析英汉论辩语篇中的言据性策略来研究说话人/作者提高语篇观点信度和表述有效性的论辩语篇组织模式。

Argumentative discourse is the discourse that takes persuasion as the primary purpose, logic reasoning as the major rhetoric device, and interaction as the communicative goal. As the linguistic representation encoding the information source of the said proposition and indicating its credibility, evidentiality embodies the speaker＇ s/writer＇s assessment of information sources and his/her involvement in the propositions of discourses. This paper, through reexamining the pragmatic correlation between information source and evidential markers, explores how the speaker/writer organizes the whole argumentation through the application of evidential strategies in order to ensure the reliability of arguments and also ex- press opinions in a more effective way.
