附加問句是一個特殊的問句形式。前人研究指出，附加問句形式上雖為問句， 但明顯地疑問程度偏低，具有交際功能。但具有何種語用交際功能卻有待探究。本 研究試圖分析正反附加問句在自然會話中的使用及語用交際功能。由於考量說話者 的會話角色及當下對話情境，因此以會話分析作為方法論，選擇參與者會話角色鮮 明的烹飪綜藝節目為考察對象。結果發現，某些正反形式組合出現頻率相當高，有 些呈現情態功能，有些呈現情感功能。非主導地位的說話者，使用情態附加問句尋 求訊息的確認；具會話主導地位的說話者則使用情感附加問句尋求聽話者認同，調 節對話。本研究試圖將語言形式、語言使用、說話者會話角色與語用交際功能做一 個連結，並提供教學啓示。

The present study focuses on one particular type of questions, the tag question, in talk-ininteraction in Mandarin Chinese and examines its interactional functions. Tag questions, albeit in a question format, carry a relatively weaker force to seek information; rather, they are mainly used for confirmation seeking and thus for interpersonal purposes. The aim of present study is to investigate, based on the clips of cooking demonstrations extracted from a Taiwan cooking show, how participants interactively use and orient themselves to tag questions. Instances are particularly analyzed with respect to contextual factors and the conversational roles of speakers. This study is intended to demonstrate that it requires a systematic analysis of the situated context in which tag questions are embedded to better understand the nature and the use of this type of question.
