Question

the man had expected to see all his realatives when he was in hospital,but------came to see

him while many of his neighbours offered their help.
A none B no one
为什么选A B 为什么不行呢

Answer 1

首先看一下两者的区别：
no one
1.表示没有人，
2.作主语时，谓语动词用单数 No one is over there.
3. 回答who 问句：Who is in the room? No one.
none
1.全部否定，表示没有东西/人
2。作主语时，如果指人，谓语用复数；如果指物用单数。
None of the boys like singing.
None of the books belongs to him.
从句子意思可知，but后面是表否定的，应用none，指代前面提到的all his realatives ，是复数形式

Answer 2

no one 谓语动词用单数,none谓语动词用单或复数.
从all his relatives可以看出来应该是用复数。所以排除no one!
