none和none of 谓语动词用单数还是复数网上的答案都不一样啊

Answer 1

none of, all of 这些无法确定数量的词在主谓一致的原则下,谓语动词用单、复数都可能,一般根据后面名词来决定：

1）后面是跟可数名词复数的,谓语动词用复数：
None of his friends are going to the movie with him.
All of the students have homework to do.
2) 后面是不可数名词的,谓语动词用单数：
None of the money was stolen.
All of the time we spent on this has been wasted.
