本文从分析认知语法中的使动语法构式的原型意义入手,质疑其可行性,证明其谬误性,认为及物动词、不及物动词与语义无关。从语言的内在机制着眼,纵深挖掘不及物动词向及物动词的转化等一系列问题,有助于我们理解语法的实质。分析显示,词类由语言的结构依赖原则决定;使动语法构式的原型意义观对及物、不及物动词这一问题不具有充分的解释力。 This article begins with the analysis of the archetypal meanings of the grammatical constructions in cognitive grammar, questions its feasibility and proves its fallacy. It holds that transitive verbs and intransitive verbs have nothing to do with semantics. From the perspective of language’s internal mechanism, we can deeply understand the series of questions such as the transformation of intransitive verbs into transitive verbs, which helps us understand the essence of grammar. The analysis shows that the part of speech is determined by the principle of structure dependence of language; the concept of prototype meaning of dynamic grammatical construction does not have sufficient explanatory power to the problem of substance and intransitive verb.
