1.        A recent national study of the public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.

(A) there are now one microcomputer for every thirty-two pupils, four times as many than there were

(B) there is now one microcomputer for every thirty-two pupils, four times as many than there were

(C) there is now one microcomputer for every thirty-two pupils, four times as many as there were

(D) every thirty-two pupils now have one microcomputer, four times as many than there were（C）

偶对选C没有疑问, 但偶怎么也搞不清为什么four times as many as后面是there WERE

There IS ONE computer for every 32 pupils , 4 time as many as there WERE. 这是怎样的一个比较的结构呢? there were 和谁对应呢?

这题确实很变态！：（

不知楼主有没有看过OG的解释。可以去下载一个看看。

我个人的意见是：

there is 是表达每32个人一台，单位数字；而there were是表示所有机子，是集体概念。两者之间没有绝对平行，所以，“four times as many as there were”前面加了一个“，”，伴随说明：总体数量的大小。

不知其他NN有没有更精辟的论断。

我本人也没有办法，只能每天看它一眼，直到有一天能背下来，毕竟这是人家的语言。

用there were的原因是因为不知道后面接的是单数还是复数，当不知道是单数还是复数时，就要用复数。

在举个简单的例子，

The student who failed the class should call ----- （his，her，their）parents。因为不知道这个学生的性别就要用复数their。
