题目内容：

none和neither作主语时,谓语动词用单数还是复数?有几个例题,请帮我详细解释一下为什么用单数或是复数
None of us has ever been to the US.
None of them are my friends.
None of the passengers are aware of the danger.
Neither of the books is of any use of me.
Neither are suitable for newspapers.

优质解答

none 可以复数也可以单数
具体看语境
neither必须单数
None of us has ever been to the US.我们之中没有任何一人去过US,强调没有一个人去过,一个人,单数
None of them are my friends
他们都是我的朋友,强调一群人所以复数
Neither are suitable for newspapers绝对是病句
