问题描述:

Charles was alone at home,with not one looking after him.
答案是not one ,为什么不选no one

这一题考得到是蛮细致的.
说说几个词吧,no one none not one(这个词组很少见,但是有部电影叫not one less《一个都不能少》)
none=not one=not any
no one=nobody
no one用法: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.
none用法: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.
no one,应该就是‘没谁’,none是指‘没有人’,在本题中应该是强调的人的数量问题,所以用none.在本题中没有none就用not one.
