问一道白勇语法上的主谓一致问题

16. It is characteristic of the Metropolitan Museum of Art， as of virtually every great American museum the taste of local collectors has played at least as large a part in the formation of their collections as has the judgments of the art historian.
(A) of virtually every great American museum， the taste of local collectors has played at least as large a part in the formation of their collections as has
(B) of virtual1y every great American museum， that the taste of local collectors has played at 1east as large a part in the formation of their collections as has
(C) it is of virtual1y every great American museum，that the taste of local collectors has played least as large a part in the formation of its collections as have
(D) it is of virtual1y every great American museum，that the taste of local collectors have played at least as large a part in the formation of its collections as have
(E) it is of vlrtual1y every great American museum，the taste of local collectors has played at least as large a part in the formation of its collections as has

答案选C，除了最后一段as have，其他知识点我明白，可是这个as have，这个have的主语是谁？为什么说凭judgements是复数就能判断用have?

the taste has played as...as the judgements have的倒装吧

其实就是比较中的一个规则，主句中如果有助动词(have/has/had + done)或情态动词(can/may/must +do)，那么比较从句中可以省略相同动词，只保留相应的助动词和情态动词.

这里相同的动词是played, 对应的助动词是has和have，分别对应taste和judgements

另外，比较从句中使用倒装或陈述语气均可，所以 have  judgements 和judgements have是一样的

那楼上的意思是这里主语是taste,然后the taste has played a part of ... 和the taste have played judgements比较？可后半句不通阿，taste为什么可以用have，或者说这个倒装怎么看出来是倒装的？

songyeonpp

the taste has played as ... as the judgements of the art historians have (played)...

通常as..as的比较都把第二个动词提前，也就是倒装。如果后面的动词和前面的一样，省略后面的动词，但是情态动词和助动词不能省。。

如果没有情态动词或助动词，但是前后动词一样，第二个动词用do或者did代替。He went to Church yesterday as did I.

个人想法，欢迎批评。。
