使用代词one的若干用法注意

1. 不要在所有格（含形容词性物主代词）之后误用one或ones，可直接使用所有格或将形容词性物主代词改为名词性物主代词。如：

我们需要一架梯子。我们可以借邻居的。

误：We need a ladder. We can borrow our neighbour’s one.

正：We need a ladder. We can borrow our neighbour’s.

我找不到我的钢笔了。你能把你的借给我吗?

误：I can’t find my pen. Can you lend me your one?

正：I can’t find my pen. Can you lend me yours?

2. 不要在基数词（two, three等）后误用one或ones。如：

杰克是三人中跑得最快的。

误：Jack is the fastest runner of the three ones.

正：Jack is the fastest runner of the three.

他养了三只兔子，我只养二只。

误：He has three rabbits and I have only two ones.

正：He has three rabbits and I have only two.

3. 不要在both后误用one或ones。如：

第4题和第5题选做一道，但不要两道都做。

误：Do question 4 or question 5, but not both ones.

正：Do question 4 or question 5, but not both.

4. 不要在one’s own 后误用one或ones。如：

他们待这孩子像亲生的一样。

误：They treated the child as if she were their own ones.

正：They treated the child as if she were their own.

那些书是图书馆的藏书，但这本是属于我个人的。

误：Those books belong to the library, but this is my own one.

正：Those books belong to the library, but this is my own.

5. 不要在some或any后误用one 或ones。如：

我没有鸡蛋了，因此我出去买了一些。

误：I hadn’t any eggs, so I went out to buy some ones.

正：I hadn’t any eggs, so I went out to buy some.

假如有错，就把它改正过来。

误：Correct errors, if there are any ones.

正：Correct errors, if there are any.

但是，值得注意的是，若one / ones前有形容词修饰，则可以用于所有格、基数词以及some, any, both等之后。如：

My cheap camera takes better pictures than his expensive one. 我的相机便宜，但比他的昂贵相机拍出的照片还好。

“Did you get any postcards?” “Yes, I bought four nice ones.” “你买明信片了吗？”“买了，我买了四张精美的明信片。”

I bought some sweet ones today. 我今天买了一些甜的。
