A policeman or two or three is to help them out of the trouble
or不是就近原则的嘛,谓语动词怎么是is?不是are啊!求详解,
答
"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 reasoms were suggested . 提出一两条理由....这个和or就近原则没关系嘛？按照上面的解释，题中用单数复数都可以，如果one or two or three policemen，则只能用谓语动词的复数形式了，我也是找了一大堆，大部分的解释都是这样的。单数应该好些吧，复数也不能说就是错的，语言本身就很灵活的，你可以这样理解，or two or three 在这更多像with，主体在前面A policeman，嘿嘿，这些都是细枝末节，应试教育把我们都教坏了:-D哦 觉得这个应该要用复数，Neither you nor I nor anybody else knows anything about it. 和A policeman or two or three is to help them out of the trouble有点异曲同工的感觉or two or three着重在于"附加说明"更像with ，只能这么揣摩了。而Neither you nor I nor anybody else 三个是并列的成分，就进原则，和anybody else一致
