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(C)
(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?
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
