134. 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 raisedproduction 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
C选项无疑是最好的答案,平行的同时使用 while 表达了一个相反的意思。
D And is required to link the parallel elements; the verb reduced applies to all three parallel
elements, so inserting lowered before fatigue illogically suggests that fatigue actuallyincreased
我理解og的意思,但是总觉得它的这个解释不是那么的常规。。。
Recently implemented “shift-work equations” based on studies of the human sleep cycle have reduced sickness, sleeping on the job,(have)lowered fatigue among shift workers, and (have)raised production efficiency in various industries.
没有这种结构的原因是 have 不能省略还是什么的…
