no，none和no one的用法区别：

no=not a或not any,通常用作定语,可以修饰单数名词或复数名词，也可以修饰不可数名词。none不定量,意为“一个也没有”,用作名词时,在句中一般作主语或宾语。none代替不可数名词作主语时,谓语动词用单数形式;如代替可数名词作主语,谓语动词可用单数或复数形式。no one指人，意思是“无人”“没有人”,永远用单数。例如:

He has no sister.

他没有姐妹。

She knows no French.

她不懂法语。

None of the stories are interesting.

没有一个故事有意思。

No one knows him here except me.除了我，这儿没人认识他。注意:

①在回答how many或how much引出的问句时,常用none来表达“一个也没有”的意思。例如:

-How many boys are there in the room?

屋里有多少个男孩子?

一None.

一个也没有。

②在回答“有没有.....”或“谁.....”的问句时,如果想回答“没有”,就用no one。例如:

-Is there a foreign boy in your class?

你们班里有外国男孩吗?

一-No one.没有。

一-Who has taken away my book?
