情态是人际功能的重要组成部分,在政治话语中尤其重要。本文以Halliday的系统功能语言学为依据,以30篇英美政界人物的电视访谈文本为语料,对采访双方使用的不同情态动词的量值进行人际意义分析,旨在揭示采访双方如何通过不同量值情态词的使用来表达人际意义。研究结果表明,对话双方在情态动词的量值使用上体现了一定的共性和差异性,不同量值的情态动词的使用在一定程度上受到“交际角色”和“社会角色”的影响。情态动词的量值不仅表现对话双方的权势地位关系,也表现交际双方的互动关系。本研究为政治话语的解读提供了一个新的视角。

Modality is one important part of the interpersonal meta-function, which is particularly essential in political discourse. Based on Halliday's Systemic Functional Grammar, this paper tries to analyze the interpersonal meanings of the values of modal operators of 30 English political interviews in order to see how interpersonal meanings are revealed through the usage of different values of modal operators. Results indicate that both sides tend to use similar and different amounts of modal operators with different values. The use of different values of modal operators by the interviewers and the interviewees is influenced by both social roles and roles in the interaction. Usages of different values of modal operators not only show the power relationships, but also show the interaction of the participants. This study hopes to provide a new perspective for understanding political discourse.
