对语篇衔接的研究一直众说纷纭,有些是从形式的角度来研究,有些则是从语义的角度来研究,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,尽管衔接由形式特征来体现,但衔接本身是一个语义概念。 The research on the cohesion of discourse has been divided widely, some of them are studied from the perspective of form, while others are studied from the perspective of semantics. This disagreement has caused much controversy. However, from the perspective of systemic functional linguistics, though the cohesion is embodied by the formal features, the cohesion itself is a semantic concept.
