本研究旨在討論新聞記者如何運用語用學之「前提」概念來引導受訪者回答，藉由「丟面子問題」質疑並挑戰受訪者「答非所問」之迴避回應。個案研究以一則平面政經新聞報導為言說分析之例，從主張與前提兩個語言單位來探究前提在訪談問答間扮演何種角色與功能。 相關語言學文獻討論曾指出記者前提影響受訪者之回應面向。本文進一步認為，記者訪談前提往往誘導受訪者針對該前提回應(而非針對問題本身)，並藉助記者的背景知識與訪談對話以預設前提並挑戰受訪者。 歸納個案文本的言說分析與個案記者訪談後，本研究發現，記者前提所產生的命題確實影響並誘導受訪者回應，並以記者的前設知識來探討前提技巧如何獲得受訪者更多、更深入的回應。整理上述提問、回應模式，本研究擬出語用前提作為「問好問題」之言談方法及雙方互動的橋樑，盼能提供訪談者一套語言策略。 / The goal of this research aims to explore how pragmatic presuppositions in news interviews influence the interaction of interlocutors, conducted by discourse analysis on assertions and presuppositions within each pair of questioning. By identifying the face-threatening questions which ends up leading the interviewee to non-reply responses, the case study concentrates on one public-figure interview in attempts to unveiling the tactics of placing presuppositions, added by the in-depth interview with the journalist of the case to take the speaker’s meaning into account. The result of this research enabled the author to discover the interaction of presupposition in the form of propositions between the interlocutors that leads the interviewee’s response to challenge the journalist’s presuppostions. The researcher also found evidences indicating the presumption of the journalist produces presuppostion as well as the response, which enables this research to develop a pragmatic strategy of news interview based on the use of presuppositions.
