语篇对于连贯的依赖似乎更为明显,衔接方式得当但语义不贯通的话语不是合格的语篇,衔接方式不明显但语义贯通的话语是合格的语篇;立足于语篇的基础理论,有利于我们提高对衔接与连贯的理性思考,可有效地防止在语篇分析过程中出现较大的偏误。目前主要是从语用学角度对幽默进行研究,本文试从系统功能语言学理论出发去探讨幽默语的语篇衔接与连贯机制,以促进对幽默语的理解、使用。 The discourse seems to be more obvious to coherence dependence, the cohesion way is proper, but the discourse which the discourse does not pass through is not the qualified discourse, the discourse mode which is not obvious but the semantic meaning through is the qualified discourse. Based on the basic theory of discourse, Which will help us to improve the rational thinking of cohesion and coherence, which can effectively prevent large errors in the discourse analysis process. At present, mainly from the perspective of pragmatics to study the humor, this paper try to explore the discourse cohesion and coherence mechanism of humorous language from the perspective of system functional linguistics to promote the understanding and use of humorous language.
