Halliday & Hasan[1]认为“衔接”这个词专门指那些组成语篇的非结构性关系,它们是语义关系,衔接是语篇中的一个成分和对解释它起重要作用的其他成分之间的语义关系,这一“其他成分”也必须在语篇中能找到,但它的位置完全不是由语法结构来确定的。这样,语篇的衔接机制就被局限于能够在语篇形式上找到其 Halliday & Hasan [1] consider that the term “convergence” refers specifically to those non-structural relationships that make up the discourse, which are semantic relations, that cohesion is a component of a discourse and other components that play an important role in explaining it The semantic relationship between the “other components” must also be found in the discourse, but its position is not determined by the grammatical structure at all. In this way, the discourse cohesion mechanism is limited to being able to find it in discourse form
