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
(E) every thirty-two pupils now has one microcomputer, four times as many as
答案是C
不明白的是C中用的 were,XDF老师的解释如下,
为什么补出的助动词是were呢?
有一台计算机对于每32个学生是4年以前的四倍,什么东西是4年以前的四倍?计算机整体数量是4年以前的4倍,现时不是说人是以前的4倍,因为社会的发展嘛。有一台计算机对于每32个学生,那么是不是说四年以前有四分之一台呢?是指今天计算机整体数量是四年以前的整体数量的四倍,是计算机整体概念的比较,所以四年以前计算机的整体数量一定超过一台啊,所以补出there were
我不明白的是前面用的是there is,表示每一台计算机对32个学生,后面为什么不能用there is表示每一台计算机对32个学生,这样不也是对称吗??? |
