OG 89, 迷惑

OG-SC 89:     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）

(E) every thirty-two pupils now has one microcomputer, four times as many as

答案C没有问题，但是从D. every thirty-two pupils now have 和E. every thirty-two pupils now has, 我无法搞清楚: every thirty-two pupils如果做主语，谓语动词到底应该用单数还是复数。

Every thirty-two pupils has one microcomputer.fficeffice" />

或Every thirty-two pupils have one microcomputer. 哪一个是对的？我查了几个语法书，都只有 every (two, three…) noun 结构做宾语的例子。

请NN解惑。

一般用every 或 each 来形容的东西都用单数动词。fficeffice" />

当两个或两个以上{单数}{主词}由and连接,并用each,every,no等词修饰时,{主词}在意义上可能是{复数},但{述语动词}必须用{单数}形式。
