对语篇的衔接一直有各种不同的定义,有些是从形式的角度来界定,有些则是从语义的角度来界定,这种分歧引发了许多争议。然而,从系统功能语言学的观点来看,尽管衔接是由形式特征来体现的,但衔接本身是一个语义概念。 There are always different definitions of discourse cohesion, some of which are defined from the perspective of formality and some of which are defined from the perspective of semantics. This disagreement has caused much controversy. However, from the perspective of systemic functional linguistics, although the cohesion is embodied by the formal features, the cohesion itself is a semantic concept.
