Question

如one or two students 做主语，谓语动词是用单数还复数？

Answer 1

one or two students 做主语，谓语动词是用复数
a / an + 单名+ or two " 大多接单数谓语： "one or two + 复名"接复数谓语。

Answer 2

a / an + 单名+ or two " 大多接单数谓语： "one or two + 复名"接复数谓语。e.g.
①Only a word or two is (are )needed. 只需说一两句。
②One or two reasons were suggested . 提出一两条理由。

Answer 3

复数，因为英语中有一个就进原则， 而离谓语比较近的就是two students 所以用复数
