Analysis of the Characteristics and Discourse Functions of the Discourse Marker “Laughing to Death”

本文结合CCL和BCC语料库中关于话语标记“笑死”的句子，从三方面对其进行分析，第一方面是“笑死”作为话语标记的特征，主要体现在它的独立性，可用于句首、句中和句末，前后一般有停顿；具有非真值性，不会增加句子想要展示的命题内容；可以调节言语交际行为。第二方面是“笑死”的话语功能，从语篇建构功能来看主要用于话题标记和对比标记，从交际互动功能来看主要用于确立认知和增强语力。第三方面是针对前人结论的一点思考，近而提炼出搭配“笑死”在长期使用中产生的“平淡叙述 + 笑死 = 苦笑/嘲讽”的话语功能。This article combines sentences from the CCL and BCC corpora regarding the discourse marker “laughing to death” and analyzes it from three aspects. The first aspect is that “laughing to death” is a characteristic of discourse markers, mainly reflected in its independence, which can be used at the beginning, middle, and end of the sentence, with pauses before and after; has non truth value and does not increase the proposition content that the sentence wants to display; it can regulate verbal communication behavior.
