GMAT高频词汇than用法实例讲解

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

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

选项分析：

首先，用making现在分词形式做目的状语没有什么疑义

然后我们可以把题的结构简单改为：A large rise in the number of housing starts will make the economic health more robust than ....

1. 如果than后面是"it was five years ago", 句子比较的是经济状态，意思是"比5年前的经济更robust";

2. 如果than后面是"did it five years ago", 句子则强调动作，意思变成"5年前即使得经济很robust，如今则更甚"

如果省略it was会引起歧义

所以最后答案是C
