标题: og233
233. 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) lowered fatigue among shift workers, and raised
(E) and fatigue among shift workers was lowered while raising
如果B加 and (fatigue),是不是这个更对?

同问,还有A,仅仅是fatigue前没有加and所以错吗?and have raised没错吧?

以下是引用yukon在2005-4-30 20:47:00的发言:

是的,因为这是格list的表示方法,最后一个列举对象要加and
若是用and have raised或是raised就不能表达while raising的对比的意思了

请问可爱版主, 我想说一下我的理解,能不能帮我看看是否正确
句子结构 :
equation have reduced sth1, sth2, and sth3 while raising sth4
sth1, sth2, and sth3, 三者平行 所以最后一个里要加上逗号
但是 为何 have reduced......while raising 就平行了呢?这样的时态对比正确嘛?
为什么 have reduced....., and have raised... 就表达不了对比的含义了?

我好像明白了, 这里的raising 在句尾, 是否表示伴随的结果,
equation 降低了1, 2, and 3, 同时 (作为它的结果) 增加了 4,
而这里, raising 比 have raised 好, 是因为它准确的表达了一种正在发生的状态,
而have reduced 现在完成时, 则是表达了一种 sth that happened before now,at an unimportant time in the past, 用现在完成时最恰当
不知道这样理解对不对
