no one和none的区别There is no one else in the classroom是否等于There is none else in the classroom

不可以。no one 一般用来指人，none 除了指人，还可指物。no one 可单独做主语，none 一般后面加介词OF .

1.none既指人也指物，而no one只指人;2.none后可接of短语，而no one不可以;3.none回答how many/how much的问句，而no one回答who的问句。

1.no one
1)不与of连用；2)谓语动词用单数；3)只能指人,但不具体指什么人；4)一般用来回答who,及含
anyone,anybody引起的疑问句.如：
1)No one likes a person with bad manners.
