会话语境中因果连词的话轮衔接功能
Turn-Taking Function of Causal Conjunctions in Conversational Context

本文主要讨论会话语境中不同的因果连词能否直接衔接前后话轮。本文选取因果连词“因为”“所以”“因此”“于是”“既然”和“由于”作为研究对象，结合具体语料，分析它们在会话语境中是否能够在说话人和听话人分别提出原因和结果时，出现在第二个话轮之首，衔接起分离的原因和结果，即它们是否能够直接衔接前后话轮。经研究得出：“因为”“所以”“因此”“于是”具有话轮衔接功能，能够直接衔接前后话轮；而“既然”和“由于”的话轮衔接功能是有条件的。
This paper mainly discusses whether different causal conjunctions can directly connect the front and back turns in conversational context. In this paper, the causal conjunctions “because”, “so”, “therefore”, “then”, “since” and “because” are selected as the research objects, and combined with specific corpus, it is analyzed whether they can appear at the head of the second turn when the speaker and the listener put forward the reasons and results respectively in conversational context, so as to connect the reasons and results of separation, that is, whether they can directly connect the previous and subsequent turns. Through research, it is concluded that “because”, “so”, “therefore” and “then” have the function of turn cohesion, which can directly connect the front and back turns; The turn cohesion function of “since” and “because” is conditional.
