233. 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
(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
The best answer, C, grammatically states that the equations... have reduced x, y, and i. and have raised efficiency. Choices A and B fail to use and to signal that fatigue among shift workers completes the series begun by have reduced, and so produce awkward and unclear sentences. Both D and E fail to use and to introduce the last item in the list, which is sleeping in these constructions. In E, while raising has no logical referent, producing only the absurd statement that fatigue has raised efficiency.
根据解释,C项应该是 and fatigue among shift workers, and have raised
不知是不是前人早已经说过的,见笑了
anyway, 如果是,下载版的文件应该改一下哦!
and fatigue among shift workers while raising
如果转成非省略说法,应该如何?
是否成为:and fatigue among shift worker while Recently implemented "shift-work equations" have raised ...
那么上面的while raising为什么不是while raised呢?
帮zhuzhu1973顶。我也想知道这种主语相同的while从句转化成分词结构的规则。哪位大哥给点线索?
while conj. during the time that; when:
He fell asleep while (he was) doing his homework.
While (locked up) in prison, she wrote her first novel.
while conj. during the time that; when:
He fell asleep while (he was) doing his homework.
While (locked up) in prison, she wrote her first novel.
while后面是只要主语和时态与主句一致,就能省略,是么?
请问此处可以使用“
and fatigue among shift workers while raised”吗?看成是while have raised的省略?
我认为是可以的。
主语没有变化。只不过一个是完成时态一个是进行时态。从句子的逻辑意思来看,并没有线索说明必须用进行时。
请问此处可以使用“
and fatigue among shift workers while raised”吗?看成是while have raised的省略?
不可以吧,这里raised会被看作过去分词,只有用现在分词raising才使得逻辑主语成为raising这个动作的发出者

我对while的用法还是有疑问,哪位能帮忙总结一下while在类似的情况下的规律?while raising是不是伴随状语?谢谢
