补充 170 继续困惑ing

170.       A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than five years ago.

(A) making the construction industry’s economic health much more robust than five years ago

(B) and make the construction industry’s economic health much more robust than five years ago

(C) making the construction industry’s economic health much more robust than it was five years ago

(D) to make the construction industry’s economic health much more robust than five years ago（C）

(E) in making the construction industry’s economic health much more robust than it as five years ago

就是c 和a的区别.我看前人讨论,一直困惑于心. 是否有可能答案搓掉???

A的省略有问题。口语中或非正式文章这样应该是可以的，因为可以用语义判断。但是标准书面语不可以，因为从语法上分析不通：比较前项没有时间状语，所以这个five years ago没有对应的状语前项，那么five years ago这个名词就只能和比较前项中作别的成分的某个名词短语比较。从语义上来讲这是不可能的。标准书面语是可能要被反复的阅读的，所以必须严格按照规范，语义和语法上都要经得住推敲。

C补出主谓，没有问题。

所以这就是GMAT语法的思维。要挑选最符合语法，正常逻辑意思，习惯用法，最简洁和最经得起推敲的选项。
