标题: 请教og134

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 raisedC

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

D选项如果前面加and,即 have reduced sickness and sleeping on the job, lowered fatigue among shift workers, and raised     就没问题了,另外这种情况下lowered以及raised前面是不是一定要有have?

我觉得这个不是有没有have的问题,而是逻辑上对比的问题
文中想说human sleep cycle可以带来三个结果,形成对比的是,while提高的生产效率
楼主请看,前面三个动作是有内在联系的,都是说减少了不好的方面,后面的生产率提高时因为这三个方面reduce了,所以用了while形成对比。
OG里面还有31  131等,都是表示对比的用法

谢谢楼上,似乎我的思路有点问题,做的时候一下子就被带到平行上面了。是不是对比的优先性还是要大过平行?og31 131?是og10吗
