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
C.there is now one microcomputer for every thirty-two pupils, four times as many as there were
E.every thirty-two pupils now has one microcomputer, four times as many as
由于手打的，所以就列出这两个选项，答案是C，我想问E错在哪呢，上新东方的时候老师说has不对，这里表示不是拥有，只是客观对应。我没懂，到底是怎么回事呢？

every thirty-two pupils 做主，谓动用复数。
