人们对名词和定名短语的差异的问题关注得不够。本文发现二者的差异是客观存在的,并有选择地从“充当分句的差异”和“语用差异”两个方面展开探讨,把差异归纳为:同现分句的类型、分句间的关系类型、分句间的结构层次的差异,信息传递(预设、焦点)、表述功能的差异。 People have not paid enough attention to the differences between noun and noun phrases. This dissertation finds that the difference between the two is an objective one, and it is explored from two aspects: “the difference as the clause” and “the pragmatic difference” selectively, and the differences are summarized as follows: the type of the co-occurrence clause , The type of relationship between clauses, the structural differences between clauses, information transfer (presupposition, focus), and the difference of presentation functions.
