我个人觉得可以象如下这样理解，不过我不保证正确啊。

１、先举一个简单点的例子
　　There    are    8    computers    in    this    classroom,    4    times    as    many    as    there    (    )    in    that    classroom.
　　上面这个例子要表达的这个教室有８台电脑，是那个教室里的四倍。谁都知道括号里应该填写的是are，而不是is。

２、变换一下
　　There    are    8    students    in    this    class    room.
　　There    is    one    computer    for    every    student,    four    times    as    many    as    there    (    )    in    that    classroom.
　　这个句子比上面那个句子加了一个前提，就是教师里有8个学生。每个学生有一台。描述的是同样一个道理，你觉得括号里应该是填are还是is呢？

３、如何解释这个题目
　　前半句there    is    now    one    microcomputer    for    every    thirty-two    pupils和后半句there    were    four    years    ago，它们两句话所表达的倍数关系是什么物质的倍数关系呢？肯定是电脑台数的倍数关系，并不是平均每台电脑的使用频率上的倍数关系。既然是电脑台数的倍数关系，那么我们可以肯定，四年前肯定不是只有一台电脑吧。那么肯定要用were。前半句是用一台电脑的使用人数来表达电脑的台数，后半句直接使用数字个数来表达电脑的台数，所以要用复数。

４、大家再看一个句子
　　There    is    one    computer    for    every    4    student    in    this    classroom,    four    times    as    frequently    used    as    there    ()    in    that    classroom.
　　大家想想看，这个题目要用are还是is。

不知道讲清楚了没有，如果没有可以再问。

AGREE.

you said it , 1/32------1/128, there are (128 电脑,) 是四年前的四倍.

前面NN们的说法好象在语法理论上是站不住脚的啊。我也想不出有什么很正当的语法依据来justify were的用法。我在做这题上时是靠排除法选了C。

时隔这么久，有没有NN后来又有新的心得可以分享给大家呢？

其它例句：
While 18 per cent of the high-tech workplace is filled with women, that's half as many as there were 25 years ago。
The number of registered voters in the county is 18,058, almost twice as many as there were four years ago .

斑竹可把此贴链接到OG89题的讨论中去以便大家查找，这个帖子关于WERE的问题是讨论最深入的一个。谢谢！

我又细看了一下，觉得bunnier的解释理论上应该比较正确也容易掌握：

89C: A recent national study of the public schools shows that here is now one microcomputer for every thirty-two pupils, four times as many [microcomputers] as there were.

有这样的一种说法：老外数学不好，又懒得算，于是订下了一条规矩，如果不用计算,单复数一致，such as, there is one computer for, or there are two computers for；如果需要计算不论简单复杂，不管3721一律用复数，such as, four times as many as there were two years ago. Or there are now two computers for each group, two times as many as there are two years ago. 他们到是简单了可难坏数学好的XDJM了。
