本文运用形式语义学的方法对“都”作为全称量词的独立性和准确的定义问题进行了考察。认为“都”不属于典型的全称量词 ,在一定条件下 ,“都”具有对有关名词组 (NP)分配事件 (VP)的功能。 This paper examines the independence and accurate definition of “都” as the full quantifier by using formal semantics. It holds that “all” does not belong to the typical full quantifier, and under certain conditions, “all” has the function of assigning events (VPs) to relevant NPs.
