no one,none用法有什么区别啊

B,理由如下：
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 like a person with bad manners.
2)——Who is in the room?
——No one.
3)——Is there anyone in the room?
——No one.
2.none
　　1)可与of连用；2)谓语动词用单或复数；3)具体指什么人或物；4)一般用来回答how many +n,how
　　　much +n及含any+n引起的疑问句.请看：
　　1)None of us have/has seen him.
　　2)——How many students are there in the room?——None.
　　3)——Is there any water in the thermos?——None.
　　4)——How much money do you have on you?——None.
下面的顺中溜将帮你记得更清楚.
　　No one与none好分辨./具体人,物把none填.
　　不知何人与何物,/No one nothing是一路.
　　No one人nothing物,/保你不会出错误.
