none的用法是什么啊?
1.none 与 no one / nobody 及 nothing
no one / nobody 常用来指人,作主语时谓语动词要用单数形式;nothing 常用来指物,作主语时谓语动词也要用单数形式;none 可指人也可指物,作主语时,如和 of 连用指不可数名词时,谓语动词要用单数形式;指可数名词时,谓语动词用单、复数均可.如:
No one likes a person with bad manners.
Nothing is difficult in the world if you put your heart into it.
None of them has / have seen me before.
None of this money belongs to me.
注意:
1 ) none 可与 of 连用表示范围,而 no one / nobody 及 nothing 不可.
2 ) none 可用来回答 How many / much…?的特殊疑问句;而 no one / nobody 及 nothing 则分别用来回答 Who…?和 What…?的特殊疑问句.如:
— How many birds are there in the tree?
— None.
— What is in the box?
— Nothing.
— Who is in the classroom?
— No one / Nobody.
3 ) none 可用来回答“ any + 名词”构成的一般疑问句:而 nobody 和 nothing 则分别用来回答由 anybody 和 anything 构成的一般疑问句.如:

— No,nothing.
4 ) none 可用来指代前面提到过的人或物;如无指代时可用 no one / nobody 及 nothing .如:

2.none 与 not all / all…not
not all / all…not 表示三者或三者以上的部分否定;而 none 表示三者或三者以上的全部否定.如:

3.none but,nobody but 及 nothing but
nobody but 表示单一概念,谓语动词用单数形式;none but 可指人也可指物,通常指前面提到的同一事物,谓语动词要用复数形式; nothing but 泛指 but 后事物以外的任何事物.如:
Nobody but he is often late for school.除他以外,没有人上学常迟到.
None but fools have even believed it.除了傻瓜,没有人相信这一点.
