134. Recently implemented “shift-work equations” base 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
答案是C是选对了,但是我是用平行结构做出来的,但是还是觉得while后面直接加raising还是很可疑。
我的理解中:
while只能加句子,如果从句的主语和谓语be和主句相同可以省略……
那么难道在这里,是while (shift-work eauqtions) (are) raising?
