six months为什么是单数

问题描述

精选答案

(1)基数词+(minute,hour,day,month,years)表示一个具体具有多个数量组成在一起含义时间概念时，作主语谓语用复数。

Six months have elapsed since she went to Shanghai.(2)基数词+(minute,hour,day,month,years)表示一个整体的抽象时间概念时，作主语谓语用单数。Six months is a long time.如果数量概念被看作一个整体，谓语动词用单数；如果说话人侧重在一个个的个体，谓语动词就用复数。比如:Twenty years in prison was the penalty he had to pay.在这里，我们把twenty years看作整个的一段时间，意义上是单数，所以谓语动词用单数。如果我们把侧重点放在一个个的年份上，而说“自从他被送进监狱，二十年已经过去了”：Twenty years have passed since he was sent to prison.在这里，twenty years不论在语法形式上还是在意义上都是复数，因此，谓语动词用复数。类似的例子还有：Fifty-six dollars was stolen from the cash rigister.Fifteen miles seems like a long walk to me.There were three quarters of milk in the refrigerator.
