标题: OG-223

Recently implemented “shift-work equations” based on studies of the human sleep cycle have reduced sickness, sleeping on the job, fatigue among shift workers, and have raised production efficiency in various industries.

(A) fatigue among shift workers, and have raised

(B) fatigue among shift workers, and raised

(D) lowered fatigue among shift workers, and raised

(E) and fatigue among shift workers was lowered while raising

偶用排除法知道答案是C。但不明白while表转折前后应该尽量平衡。用ing在它后面怎么讲？

多谢！

现在只有GMAT有Office Guide做的吧～

xx2004是不是把原本应该贴到GMAT版的帖子贴到TOEFL版了～

一看题目就愣了一下，5个选项，要吓死这里胆小的家伙呀～

嚯嚯～

and 是需要平行结构的，while 尽量平衡倒是没有听说过，排除法也是好方法（长时间不碰GMAT了，回答不上来了）～

CD上有GMAT专区的～

CD版主竭诚为您服务，也请支持CD；有事您打贴；有错误请指正，谢谢。
