本文首先介绍了语境理论,特别是功能主义的情景语境及其对应语言的三大元功能,连同语篇连贯性的有关理论,提出语境与语篇连贯性的密切关系。接着本文尝试运用功能语言学的理论视角分析一段电影对白语篇中的情景语境来说明情景语境在分析对白语篇连贯性方面起着关键的作用。 This paper first introduces the context theory, especially the functional context and its three major meta-functions of the corresponding language, together with the theory of discourse coherence, and puts forward the close relationship between context and discourse coherence.
