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）

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

我感觉c这里的there is 和there were是否单复数上要一致啊？还有E是否错在动词has,要是改成have是否就正确啦？谢谢

(1)there were的单复数与其后面的表语一直，后面省略的可能是类似于

microcomputers for ....

(2)E即使改为have，也不是好的选项，microcomputer是学校的，给学生用的，

不是学生的。
