Each year companies in the United States could save as much as $58 billion annually by preventing illness among employees and gain as much as $200 billion through improving performance of workers if they simply provided offices with cleaner air.


       A    annually by preventing illness among employees and gain as much as $200 billion through improving performance of workers if they simply provided

• B    annually if they prevented employee illness and gain as much as $200 billion through worker performance improved by simply providing  
• C    annually in employee illness prevention and gain as much as $200 billion through worker performance improved by simply providing  
• D    in employee illness prevention and gain as much as $200 billion through improving performance of workers if they simply provided  
  
• E    by preventing illness among employees and gain as much as $200 billion through improved worker performance if they simply provided  
  
  

这道题的解法其实很简单，估计用时也就是40s, 首先 annually 与 each year 重复所以排除 ABC，在DE 中，因为save money in something prevention 不是 idiomic 的用法，所以排除！！！

这是prep 07 SC 1 的82题，这道题在做的时候有些费时，更严重的是，因为刚开始看到这个题没有找到突破口，但是第一遍看完，因为有 and gain 所示认为是在重点考察平行结构，
因此在这里我的第一个问题是大家认为这道题考察的重点到底是什么？如果是平行结构为什么在五个选型中and gain as much as much as $200 billion 的结构完全一样？在此我认为其实gmac 其实在这里是在误导我们的的注意力。


第二个问题是，有没有人在做这道题的时候会想，each  year companies in the US could save  as much as $58 billion by preventing illness among employess 或者是 each  year companies in the US could save  as much as $58 billion if they prevented employee illness 这两种说法一个表示方式，一个表示假设 其实都可以
