问题描述:

a recent national study of the public schools shows
A recent national study of the public schools shows that there is now one microcomputer for every thirty-two pupils,four times as many as there (were) four years ago
请问这里there后为什么是were哦?

有的意思
there is now one microcomputer for every thirty-two pupils,four times as many as there (were) four years ago
现在每三十二名学生有一个微型计算机是四年前的四倍为什么不用was 呢?与many一致是指as many as there were four microcomputer for every thirty-two pupils?怪怪的应该是a microcomputer for every one hundred twenty-eight pupil可是前面的thirty-two也是用is啊这个问题我也有疑问,我也解释不清了。
