政治演讲语篇责任型情态的人际意义研究——以奥巴马每周演讲为例

A Study on Interpersonal Meanings of Deontic Modality in Political Speech:Obama's Weekly Addresses as Examples

本文以系统功能语言学关于情态和人际功能的论述为出发点,结合评价理论的介入语言资源,并参照van Dijk的意识形态分析理论,通过对30篇奥巴马每周演讲中责任型情态的数据统计和语言例证考察,发现政治演讲语篇多选用义务性责任情态、高量值的责任型情态以及主观的责任型情态,既表明了演讲者的态度和立场,又体现了演讲者与听众的社会心理距离,更重要的是责任型情态的运用开启了政治演讲语篇主体间的多声协商,通过运用权力和操控听众来传播演讲者及其所代表的政党的意识形态。

Taking Systemic Functional Linguistics and Appraisal Systems as its theoretical framework,this paper explores deontic modality and its interpersonal meanings in political speech from the perspective of van Dijk's model of ideological analysis.Based on statistics and illustration of 30Obama's Weekly Addresses,this study finds that the speaker prefers obligation,high level and subjective deontic modality devices,which have multiple interpersonal meanings,namely,expressing attitudes,satisfying social psychological strategy.And above all,deontic modality in political speech is the token of engagement of interacting stances and voices,uses power,manipulates the public,and spreads the ideology of the speaker and the political party the speaker represents.
