【求NN】prep笔记181 关于比较、double

豆菲

181. 重点题The number of people flying first class on domestic flights rose sharply in 1990, doubling the increase of the previous year.

A.doubling the increase of

B.doubling that of the increase in

C.double as much as the increase of

D.twice as many as the increase in(A)

E.twice as many as the increase of


笔记里说“注意doubling the increase of 和 double as much as the increase of是两个完全不同的结构”
不同在哪里？

白勇语法里面说
double 可用于主动也可用于被动，但是 不能和as搭配

还有http://forum.chasedream.com/GMAT_SC/thread-263606-1-1.html这个帖子里面说
“如OG 中出现的 the number ...greater than / more than 的错误”
the number ...greater than 不对么？

是说前者是伴随状语，后者是同位语修饰？double as much as是同位语修饰词怎么解释
