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

可不可以請各位解釋一下，C和E有何不同，看來E只比C多了was lowered，這樣就會破壞x, y, and z的結構嗎?謝謝

我又多想到一個觀點，就是在fatigue among ....的後面多加上was lowered(選項E)，是否會有破壞句意的問題，理由是"調動工作可以減輕員工的疲倦"，如果疲倦還lowered ，是否在句意上會完全走味??

請教各位，謝謝

我怎末觉得e答案：Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced sickness, sleeping on the job,and fatigue among shift workers was lowered while raising production efficiency in various industries.让人感觉是由两个句子构成的，前个句子的谓语是reduced，后一个句子谓语是was.

之所以错是因为

1。前半句的并列部分没有and 连结（这点og没有说）。

2。这样一来后半句意思变成了fatigue among shift workers raise production efficiency了，不合逻辑，所以og解释说：In E, while raising has no logical referent（没有合乎逻辑的指代，因为它在逻辑上应该指代Recently implemented "shift-work equations）, producing only the absurd statement that fatigue has raised efficiency.）

所以怎末分析都是不对的。

不知道我的理解是不是正确，多多指教，多多讨论！

但是我又有新的问题了!  我现在翻不到..就是那个 "separate, required course" 的时候不用and老师解释说是因为同样重要的两个比较时不用加and, 而这里OG 却指出不加and 是错误的

..have reduced sickness, sleeping on the job, and ....若说同样重要也是可行的阿!

我不是很能理解, 请指教!

谢谢~~

我觉得og的意思是必须在最后一个平行前加and,之前的and可以省略,比如这里的have reduced sickness,(and)sleeping on the job, and  fatigue among shift workers......

不知说错没有

that's not what i mean, thanks still vactioner~~

up up!!!

37题诗关于adj修饰n的用法，因为多余一个的adj修饰n,对于adj的修饰先后是有顺序，而用","隔开adj就可以不必排顺  详解参见toefl语法

233题是reduce宾语并列的一个list,在这个list的最后一个element前要有and连接，表示list结束了。详解参见og190
