11. There are three libraries in our school, _____ were built five years ago.
A.all of them B.either of them
C.all of which D.both of that

选择c了

首先前一个半句子里有are了，后一个句子有were 都是谓语动词了，所以后面的该是从句了排除了a和b

又因为是3个图书馆，排除了d

所以选择c了

C
3个以上用all
是定语从句，用which代替them

c all of which

A.all of them 它们全部

a,其他三个语法都不对。
