none用于指人或指物,可与of短语连用,用作单数或复数,总是用在一定范围之内,如:
1、None of that money on the table is mine.桌子上的钱都不是我的。
2、None of us are/ is afraid of difficulties.我们当中没有一个害怕困难。
注意:
1) none of短语中的none不能用no, no one, nothing , nobody来代替,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. 他们都不认识我。
None of them don't know me. 为错误,要说成:Each of them knows me.
