Question

one和ones和the ones和the one区别

Answer 1

替代表泛指的复数名词，通常用 ones。如： Hard beds are healthier than soft ones. 硬板床比软床有利于健康。 Green apples often taste better than red ones. 青苹果往往比红苹果好吃。 We can lend you plastic chairs or metal ones. 我们可以借给你塑料椅子或者金属椅子。 These chairs have the great advantage of being much cheaper than conventional ones. 这些椅子具有比普通椅子便宜得多的优势。 替代表泛指的单数名词，通常用 one。如： Two heads are better than one. 两人智慧胜一人。 I lost my old camera; this is a new one. 我的旧相机丢了，这是一架新的。 Did you get a ticket?—Yes， I managed to get one. 你搞到票了吗?——是的，我设法搞到了一张。注：若 one 前没有形容词的修饰，则其前不能有不定冠词。比较： I’m looking for a flat. I’d like a small one with a garden. 我正在找一套公寓，想找一套小的带花园的。 I’m looking for a flat. I’d like one with a garden. 我正在找一套公寓，想找一套带花园的。（不能说：... a one with a garden.）没有形容词修饰的 one 前不能用不定冠词，但可用 another。如： This pen doesn’t work. I must buy another one. 这支钢笔坏了，我要另买一支了。另外，注意它与表特指的 it 的区别。如： Can you lend me a pen?—Sorry. I haven’t got one. 你能借给我一支钢笔吗?——对不起，我没有钢笔。 Can I borrow your pen?—Sorry， I’m using it. 我能借用你的钢笔吗?——对不起，我自己正在用。

Answer 2

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 。

Answer 3

一般来讲one代表前面有不定冠词的可数名词单数that代表前面有定冠词的可数名词单数ones 代表前面无定冠词的可数名词复数前面总带有形容词作定语不能单独使用一、the one 1、 替代事物时，三者均可用;替代人时，只能用 the one。如： Who is her husband?—The one by the window. 哪位是她的丈夫?——窗户边的那一位。注：当要替代性别不明的婴儿时可用 it。 2、 当有前置定语修饰时，只能用 the one。如： Which do you want?—The red one. 你想要哪个?——那个红的。 3、 当有后置定语修饰时，通常用 the one。如： My room is better than the one next door. 我的房间比隔壁房间好。但是，若后置定语为 of 引起的介词短语，则通常用 that。如： The population of China is much larger than that of Japan. 中国人口比日本人口多得多。二、the ones 替代表特指的复数名词，通常用 the ones。如： I’d like to try on those shoes. The ones at the front of the window. 我想试试那双鞋子。橱窗里前边的那一双。注：在口语中，也可用 those 来替代表特指的复数名词，尤其是当其后有 of 引导的介词短语或 who 引导的定语从句修饰时。如： Waves of red light are about twice as long as those of blue light. 红色光线的波长约为蓝色光线波长的两倍。三、that that用来指代“同名异物”的可数名词单数或不可数名词。例如1The engine of your car is better than that of mine. that= the engine2The book you bought yesterday costs less than that I had bought before. that= the book3The weather of Beijing is as good as that of Tianjin. that= the weather4He often tells us the news of his country and that of his country nearby. that= the news
