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) lower fatigue among shift workers, and raised
(E) and fatigue among shift workers was lowered while raising
我的問題是
這裡面有三個名詞要作平衡
可是第二個sleeping為何要用動名詞,而不用名詞sleepness??
還有,這個(D)的while不是前後也要平行嗎?
這到底是怎麼一回事阿?
