(A) fatigue among shift workers, and have raised (B) fatigue among shift workers, and raised (C) and fatigue among shift workers while raising (D) lowered fatigue among shift workers, and raised (E) and fatigue among shift workers was lowered while raising
答案 C
我觉得句子的结构是equations have reduced..... and have raised....
C 的raising表示伴随 做状语作者: someonemad 时间: 2012-3-3 21:52
谢谢解答,那如果选项A里面fatigue前面有and的话,是不是也是正确的呢?作者: imddung 时间: 2012-3-4 09:23
A. fatigue among shift workers, and have raised 就算fatigue前有and,那也不对的,不能说a..., b..., and c..., and d 且这个结构里的a,b,c结构一致,d结构不一致,不可以用and来连接d作者: HarrisZheng 时间: 2012-3-4 14:58
