话语标记“笑死”的特征及话语功能分析
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。
