22. 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
(E) every thirty-two pupils now has one microcomputer, four times as many as
it seems C is better than the others, but why is "were" used here, rather than "was"?
觉得这样的比较很别扭呢?对于每32个学生所拥有的电脑数, 现在是1个,这个数字是过去的四倍,那过去就是0.25个?
0.25个COMPUTER要用WERE吗?
PUZZLED...
望NN指教
