汉语自然会话中“是吧”与“是吗”的格式选择——确认请求中的认识立场与序列组织

Format Selection of “Shiba” and “Shima” in Natural Chinese Conversation—Epistemic Stance and Sequence Organization in Confirmation Requests

摘要: 本文采用会话分析的方法，考察汉语自然会话中“是吧”与“是吗”两种确认格式的话轮设计与序列使用。两种形式都能够把一个命题提交给接收者确认，但自然会话中的格式选择并非简单的同义替换。基于北京大学现代汉语口语语料库已转写自然会话建立的59例形式集合(“是吧”22例，“是吗”37例)，本文重点分析二者处于确认请求发起位置时所形成的认识关系及其序列后果。分析表明，“是吗”通常将候选命题保持在相对开放的状态，降低说话人对命题真值的当前承诺，并使接收者对命题作出确认、修正或进一步说明具有较强的序列相关性；“是吧”则通常建立在说话人已经形成某种候选理解、记忆或预期的基础上，在保留一定命题承诺的同时邀请接收者予以确认或认同。支持这一分析的证据不仅来自句末形式本身，也来自接收者的后续行动以及确认完成后的序列推进。本文据此将两种格式理解为确认请求内部认识立场的不同调节资源：它们一方面适配参与者既有的相对认识状态，另一方面又通过具体的话轮设计反射性地建构“谁对命题承担何种程度的承诺、谁在下一位置拥有何种确认权利”。这一分析进一步说明，汉语语气形式的互动意义需要在格式、序列位置和参与者认识关系的共同作用中加以把握。

Abstract: This study adopts a conversation analysis (CA) approach to examine the turn design and sequential deployment of the two confirmation formats “shiba” and “shima” in natural Chinese conversation. Both forms can submit a proposition to the recipient for confirmation, yet format selection in natural conversation is far from a simple synonymous substitution. Drawing on a collection of 59 instances (“shima”: 22; “shima”: 37) built from the transcribed natural conversations of the Peking University Modern Chinese Spoken Corpus, this paper focuses on the epistemic relations and their sequential consequences that arise when the two forms occupy the initiating position of a confirmation request. The analysis shows that “shima” typically keeps the candidate proposition in a relatively open state, lowers the speaker’s current commitment to the truth of the proposition, and renders the recipient’s confirmation, correction, or further elaboration highly sequentially relevant; by contrast, “shima” is normally grounded in a candidate understanding, memory, or expectation that the speaker has already formed, and—while retaining a certain degree of propositional commitment—invites the recipient to confirm or ratify it. Evidence supporting this analysis comes not only from the final forms themselves, but also from the recipient’s subsequent actions and the sequential progression after confirmation is achieved. On this basis, the paper treats the two formats as distinct resources for modulating epistemic stance within confirmation requests: on the one hand they accommodate the participants’ pre-existing relative epistemic states, and on the other they reflexively construct—through concrete turn design—“who bears what degree of commitment to the proposition, and who holds what kind of confirmation right in the next position.” This analysis further demonstrates that the interactional meaning of Chinese modal forms must be grasped through the joint workings of format, sequential position, and the participants’ epistemic relations.
