(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
我的问题是 C选型是正选 没问题 这个选型在这里是不是BETTER答案 不是BEST 答案? 因为我无法理解 while后面为什么是跟着raising? 而不是have raised 如果改这样 是不是更好
另外求 解释这里 while raising的用法 谢谢!
