[求助]OG11-4

4.     A survey by the National Council of Churches showed that in 1986 there were 20,736 female ministers, almost 9 percent of the nation’s clergy, twice as much as 1977.

(A) twice as much as 1977

(B) twice as many as 1977

(C) double what it was in 1977

(D) double the figure for 1977

(E) a number double that of 1977’s

答案D

我的问题是为什么double不用过去式doubled?那些数字都是过去的啊

因为这里的double是形容词，修饰前面的9percent

..........多谢，我惭愧。。

谢谢！还是有点不明白，这里是同位语吗？

A不对的原因是什么呢

总觉得for 1977不太对   为什么不是OF  

还有  那个DOUBLE的问题  我也想不明白
