none用于指人或指物,可與of短語連用,用作單數(shù)或復(fù)數(shù),總是用在一定范圍之內(nèi),如：
1、None of that money on the table is mine.桌子上的錢都不是我的.
2、None of us are/ is afraid of difficulties.我們當(dāng)中沒有一個(gè)害怕困難.
注意：
1) none of短語中的none不能用no,no one,nothing ,nobody來代替,只能用none.
2) none和no one都是否定的,都只用在肯定句中,如：
None of them know me.他們都不認(rèn)識(shí)我.
None of them don't know me.為錯(cuò)誤,要說成：Each of them knows me.
