请教牛牛们

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 raised production efficiency in various industries.

B) fatigue among shift workers, and raised

C) and fatigue among shift workers while raising

D) lowered fatigue among shift workers, and raised  

正确答案C, 总是觉得while raising与前不对称，总是觉得D在结构上比较容易理解，但是不符合原文逻辑。请大牛门指点。

136.  Joachim Raff and Giacomo Meyerbeer are examples of the kind of composer who receives popular acclaim while living , often goes into decline after death, and never regains popularity again.

C but whose reputation declines after death and never regains its former status.

正确答案C, 请大牛门指点这里的"its"指代什么，感觉要是指代前面的composer就不应该用its.

感谢。

偶不是NN,顺道过来瞧瞧...

我觉得its指代的是reputation...

第一题偶是用排除做的,reduce的三个对象并列,最后那个是要加and的吧

你选D的话,是不是把reduce,lower和raise并列了...

要解释我不会,求教...

感谢Jean的指点！很有帮助！
