有一读者问： 有这样一句话：
(1)The displacement of workers as individual firms discard them causes social hardships.
如何分析这个句子，尤其是as individual firms discard them?
这句话的基本结构是： 主语（名词短语the displacement of workers）+谓语动词（causes)+宾语（名词短语social hardships）。as individual firms discard them是一像是定语的时间状语从句，修饰动作名词displacement。这种用作定语的状语从句并不罕见，再如：
(2)Your visit while I was ill did me a power of good. （修饰名词visit）
(3)Julia Bell's bow when she got up to recite made me think of a chicken jerking its head. （修饰名词bow）
(4)In the weeks since Toby had begun classes , he had seen very little of the head of the school. （修饰名词weeks）
