补充题95

95.   The five hundred largest manufacturing firms in the United States produce
      goods that are worth almost as much as that of the four hundred thousand firms that     remain. 

(A) that are worth almost as much as that of the four hundred thousand firms that remain   

(B) of a worth that is almost as much as that of the four hundred thousand firms that remain  

(C) almost as much in worth as those of the remaining four hundred thousand firms  (D) almost as much in worth as that of the remaining four hundred thousand firms

(E) worth almost as much as those of the remaining four hundred thousand firms

答案是E

偶看了以前的帖子，上面说比较的是goods的价值，那么我的问题是既然比较的是价值，价值是单数才对啊，那么为什么答案E用的是as much as those of 呢?

谢谢
