Three years has passed since he came to China.中为什么用has不是说three years吗
英语中,表示度、量、衡等单位名词作主语时,即使是复数形式,也应看成是一个整体,谓语动词用单数形式.

since he came to China是现在完成时态
Three years看成单数

three years 是名词短语，虽然是复数形式，但表示单数概念，后面的动词用单数！那么哪类的名词短语是复数形式却表示单数概念呢表数量的one and a half 后面一般接复数名词，做主语时谓语动词用单数 某些名词以-s结尾，形式上是复数，但实际上作单数用，后接单数动词 表时间、距离、价格、度量衡等的复数名词或短语作为一个整体看待时，谓语动词用单数形式...

你的提问很好。
Three years has passed since he came to China.
has 是错的，应该是复数动词 have 。
考题错了。

时间，距离，度量等作主语谓语动词用单数。

像这样的字组作主语，要把它看成是一个整体，谓语动词用单数！就比如说“五年的时间并不是很长”，应该是“Five years is not long”
英语中其实有很多都是凭语感来想的，并没有什么为什么，有的时候即使是老师也只能从中找方法来记，你记住就好了。...
