Recently implemented "shift-workequations" based on studies of the human sleep cycle have reducedsickness, sleeping on the job, and fatigue among shift workers
while raising productionefficiency in various industries.
感到不解的解析:
raising做伴随状语,前面可以while表转折;如果是原因伴随,可以加thus, thereby,in effect等副词
我的疑问:
1
while
conj. 虽然;然而;当……的时候
n. 一会儿;一段时间
vt. 消磨;轻松地度过
没有副词词性,如何修饰后面的raising production efficiency in various industries?
2做状语前面不是应该加逗号吗?不加逗号则为定语
我的理解:
状语从句的省略
Recently implemented "shift-workequations" based on studies of the human sleep cycle have reducedsickness, sleeping on the job, and fatigue among shift workers while (shift-work equations are) raising productionefficiency in various industries.
同一主语,从句谓语动词为be
