传统转换生成语法基于部分动词的致使语义引入轻动词语类,并将其应用于所有的句法结构推导。本文认为,致使语义并非轻动词的语义基础。动词复合语义中的部分语义才是轻动词赖以存在的语义基础。而在句法上,轻动词能够帮助实现作格结构转换和部分三价动词的结构推导。但是,并非所有结构都需引入轻动词以实现句法推导,应该严格加以区分。 The traditional conversion-generating grammar introduces the light verb categories based on the induced semantics of partial verbs and applies them to all syntactic structure deductions. This paper argues that making semantic meaning is not the semantic foundation of a light verb. Part of semantics in verb compound semantics is the semantic foundation on which light verbs depend. In syntactic terms, light verbs can help to achieve the structural transformation of the lattice structure and the structural derivation of some trivalent verbs. However, not all structures need to incorporate light verbs to achieve syntactic deduction and should be strictly distinguished.
