在牛津词典上看到shift有如下解释:
a peroid of time worked by a group workers who start work as another group finishes.
请问老师,如何判断 worked 是过去分词还是动词?
a peroid of time worked by a group workers who start work as another group finishes.
worked后接by介词短语表示施事者,且处于定语位置,worked为过去分词作定语是毫无疑问的。网友的疑问可能是work通常是不及物动词,怎么能用过去分词作定语表示被动关系呢? 其实,work作及物动词的用法也不少,其中之一就是后接时间名词作宾语。当然这种用法也有可能被分析为时间名词作状语,work还是不及物动词。但至少牛津词典的作者认为这种用法的work是及物动词,后面的时间名词是宾语,所以采用worked的过去分词作定语,修饰时间名词。《韦氏学生词典》也是这种观点:
[+ object]
He works about 60 hours a week.
The job requires that you work some nights and weekends.
She is used to working long hours.

worked 是过去分词。worked by a group workers 作定语修饰 a period of time。
work 可以用作及物动词,与工人上班,农民种地有关系。这时,其意思是:
1. work the land:开垦/耕种土地
2. work the machine: 操作机器
3. work sb. :让某人干活/工作
4. work shifts:轮班工作
5. work a period of time:工作某个时间段
(说明:4, 5 是一回事)
shift(轮班):If a group of factory workers, nurses, or other people work shifts, they work for a set period before being replaced by another group, so that there is always a group working. Each of these set periods is called a shift. You can also use shift to refer to a group of workers who work together on a particular shift.
His father worked shifts in a steel mill.
他的父亲在一家钢铁厂轮班工作。
