比较下面4个句子,为什么有的用单数有的用复数?说的详细些吧
A day or two is just enough to finish the book.
One or two days are not enough to complete the whole project.
One and a half hours has passed.
Thirty years have passed since he left his hometown ten years ago.
A day or two is just enough to finish the book.
One or two days are not enough to complete the whole project.
One and a half hours has passed.
Thirty years have passed since he left his hometown ten years ago.
1.根据就近原则，谓语动词的形式应该跟or后面的词的形式一致，而基数词作主语时谓语动词用单数，故用了一个is
2.根据上述原则，这次or后面的是two days是复数，故用are
3.作主语的是one and a half hours不构成复数，故用单数
4.thirty years是复数，故用了have，而不用has
