不定代词指不明确指代某个人、某个事物、某些人或某些事物的代词。今天给大家重点讲解最易混淆的不定代词no、no one和none的用法区别。
1.no(没有)=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。2.no one( = Nobody)指人时，意思是“无人”“没有人”，永远用单数。3.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。例如:He has no( = not a)brother.他没有兄弟。
She knows no( = not any)Chinese.她不懂汉语。
None of the stories are( is ) interesting.没有一个故事有意思。
No one( Nobody) knows him here except Tom. 除了汤姆，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:一How many people are there in the room?
屋里有多少人?
一None. 一个也没有。
②在回答“有没.....”或“谁.....”的问句时，如果想回答“没有”，就用no one。例如:--Is there a foreign girl in your class?
你们班里有外国女孩吗?
-No one.没有。
-Who has taken away my bike?
谁把我的自行车拿走了?
- No one.没人拿。
