has been away for more than two months.I miss him,you know ,two months isn't
has been away for more than two months.
I miss him,you know ,two months isn't short.
请问这里为什么填单数啊,还有什么类似的用法吗?

正确答案为：
Two months isn't short.两个月（这段时间）不短.
把two months 当作一段时间,作为整体,当作单数,所以谓语用单数isn't.
再问：什么时候把这种当单数呢？可不可以举举其他的例子？谢谢
再答：当主语是表示时间、重量、距离、价值的复数词组时，谓语动词用单数。
如Twenty years has passed. 二十年过去了，用得单数has passed （现在完成时）
One hundred dollars isn’t much for me. 100美元对我来说不算多。 isn't 单数
