虚指there结构并非同质的语言现象， 其中 ，内部动词结构表现出限定性效应， 外部动词结构无此现象 ，且限定性效应的判断存在模糊的情况。 认为内部动词结构涉及由there 与关联体构成复合DP， 而外部动词结构涉及由there 与方位 PP构成复合 DP的分析， 将前者的限定性效应解释为虚指 there所携带的【Ind】特征的作用， 将后者限定性效应的缺失归因于there 在结构上与关联体没有发生关系， 并将限定性效应模糊的 情况归于外部动词结构准许两种不同多重一致操作的可能性， 以及某些动词存在双重属性的可能性 。

The expletive-there construction is not a homogeneous group of linguistic phenomena． Inside verbals show the Definite- ness Effect ，whereas outside verbals lack such an effect． Besides ，the judgment concerning the Definiteness Effect tends to be fussy ． The analysis which assumes that inside verbals involves a complex DP formed by the expletive there and the associate ，and that outside verbals involve a complex DP formed by the expletive there and a locative PP ，explains the Definiteness Effect in terms of the ［Ind］feature of the expletive ，attributes the lack of such an effect to the fact that there is not related to the associate in outside verbals ，and accounts for the fussiness in judgment with the possibility of two types of Multiple Agree in outside ver- bals ，and the possibility that some verbs may have dual nature．
