求救prep08语法笔记问题

原文：2.    注意doubling the increase of 和 double as much as the increase of是两个完全不同的结构。

语法笔记25页。想知道这两个结构的不同到底是什么呢？

呵呵，没题不好说啊。。。这个在于具体那道题，在于用的地方不同，本身单拿出来不好区分。。。我说说你看看对不对。。。
(1)m..., doubling the increase of n的double是动词，这里做动名词l领一个成分修饰m，是说m使n增量加倍了
(2)x (is) double as much as the increase of y的double是动词或者名词，意思是x是y增量的两倍。。。

没题猜的。。。仅供参考

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
题目是这个！因为题后讲了很多，然后就摸不到头脑了。
我觉得你说的好像挺有道理的！anyway,谢啦！我再研究下哈哈。

不过 C项 double as much as the increase of 如果改成    doubling as much as the increase of 不知道行不行啊，当然肯定wordy....看笔记也没看太明白.....

请教各位NN， 这道题中 the increase in previous year 和 the increase of previous year 有什么不一样啊？
