one除了做数词,要特别注意做代词时的用法:
one做代词,用来避免重复已提过的或是听者已知的事物的名称,辨别所谈的人或事,和其中的一个人(或事物)。
被指代的必须是可数名词,单数用one指代,复数用ones指代。
one和ones前面一般有修饰词(多数代词不能用修饰词形容)。
被指代的名词是确定的,常见修饰词有this,that,these,those或the+形容词等。

我要这个,谢谢!

— Which sneakers are yours?
— The ones with white shoelaces.
-哪双运动鞋是你的?
-白色鞋带的。
Which is your car, the black one or the white one?
哪辆是你的车,黑色的还是白色的?
被指代的名词是泛指的,常见修饰词a/an//another 和some/any+形容词

如果没有形容词,one前不能用a/an:

如果没有修饰词,一般不用ones复数名词,而用some指代:

那么,不可数名词用什么指代?
some,any或什么也不用:

如果你需要更多的钱,我可以借给你一些。
