one ,ones ,the one ,the ones用法区别
one
1）代替上文中出现过的单数可数名词,表泛指（同类但不是同一）前面可以有冠词或形容词,也可以有this或that或another,但前不能有物主代词：
e.g.:
I have lost my pen．I’m going to buy one.
This pen doesn’t work.I must buy another one.
I prefer this one to that one.
比较：
I’m looking for a flat.I’d like a small one with a garden.
I’m looking for a flat.I’d like one with a garden.
（不能说：...a one with a garden.）
2）
作为不定人称代词,可泛指“任何一个人”,有one's 和oneself形式.多用于正式文体,口语中也可用he/his代替第二个one/one's.
e.g.:
One has to take care of oneself and one's family if he can.
One shouldn't hesitate to correct his/one's mistakes.
If one wants to see the ruins,he must find his own guide.
(如果一个人想看那废墟,他必须找自己的向导.)
ones
ones是one的复数形式,常用来代替复数可数名词,表泛指,前面不用物主代词修饰,也不用these或those来直接修饰,除非ones前面有形容词：
e.g.:
I have a new coat and several old ones.
These yellow waistcoats are so small.I want those green ones.
the one
替代表特指的单数名词：
Here are six rings.Pick out the one you like best.
Hand me my coat.It's the one hanging on the wall.
Your dictionary is more useful than the one my uncle gave me.
the ones
替代表特指的复数名词：
Don’t buy the expensive apples; get the cheaper ones.
I’d like to try on those shoes,the ones at the front of the window.
Are they the ones who moved here recently?
总之：
1．one/ones用来代替前面提到过的可数名词,one指代单数,ones指代复数,所代替的是同名异物,表示泛指,可有前置定语或后置定语,也可单独使用,特指时必须加 the,用the one/ones .
