本文摘自复旦大学出版社《中学英语语法(高中第二版)》，作者魏孟勋
1、one的用法
one作代词可以代替上文中出现过的单数可数名词，以避免重复。相当于a(n) + 名词，具有泛指意义，其复数形式为ones。例如：
Could you show me a skirt? A green one, I mean.
-I’d like to have a scarf.
-We’ve go some black ones.
one(s)可以带形容词修饰词或限定词a(n), the, some, any, the next, which, this, that 等，也可以接定语从句。例如：
What a pity! The bus has gone. I’ll have to wait for the next one.
-May I look at that computer?
-Which one?
-The small one on the shelf.
Is this silver bowl the one they found in the ancient tomb?
但one不能直接被基数词修饰，如不能说two ones，six ones，但可以说two red ones，six big ones。
one还可以泛指“任何人，一个人”，属格和反身形式为one’s 和oneself。例如：
One should regard others’ difficulty as one’s own.
One should regard others’ difficulty as his own.
One shouldn’t be afraid to have one’s/his mistakes pointed out.
2、one与替代词it，so，that的区别
a)one与it
one所指的是非特指的事物，而it特指上文中提到的事物。例如:
Here is my new typewriter. You may use it.
If you don’t have a typewriter, I can lend you one.
The hat in the shopwindow was pretty. I asked whether I could try it on.
The hat in the shopwindow was pretty. I wanted to buy one.
b)so与it
某些动词后惯用so表示上文提到的事，否定回答可以在动词后用not。例如：
-Could it be true that Jeff has left for South Africa?
-I’m afraid so.
-Is Ann’s old house for sale?
-I believe not. (I don’t believe so.)
能用这种结构的动词有believe/expect/fear/guess/imagine/suppose/think/hope等。
c)one(s)与that/those
that，those特指上文中提到的名词，以避免重复，一般都带有后置装饰语。
The photograph of you is much better than that in your album.
I want a photograph of you – would you give me one?
one(s)只能用于指代可数名词。
（误）I prefer black coffee to milk one.
（正）I prefer black coffee to milk coffee.
特指上文中的复数名词those可以与the ones替换使用。例如：
My shoes are similar to those you had on yesterday.
My shoes are similar to the ones you had on yesterday.
