It和one，one和the one，the one和that，ones和the ones，that和those，that和it，those 和they七组替代词的用法区别■替代词it与one的区别一般说来，it表特指，相当于“the+名词”，表示与前面提到的事物为同一物；one表泛指，相当于“a+名词”，表示与前面提到的人或事物为同类，但并非同一。
比较：I can’t find my pen. Have you seen it?我找不到我的钢笔了，你看到过它吗？I can’t find my pen. I think I must buy one. 我找不到我的钢笔了，我想我得去买一支。
另外，注意it与the one的区别：虽然it和the one均表特指，但it后不能接定语短语或定语从句，而the one后面则通常要接定语短语或定语从句。
如：My room is better than the one next door. 我的房间比隔壁房间好。
He was the one who told the police. 告诉警察的就是他。
■替代词one与the one的区别one用作替代词主要用于替代“a＋单数可数名词”，表泛指；若需特指，则用the one。
两者均可受定语短语或定语从句的修饰。
如：A fast train is one that goes fast. 快车是一种行驶快的火车。
The accident was similar to one that happened in 2005. 这个事故与发生在2005年的事故类似。

如何用it，one，ones，that，those来指代it，one，ones，that，those可以用来代替上文中提到的名词，以避免重复。
现将其用法归纳如下：1. it 代替上文提到的名词，指代同一事物，而不指这一类中的另一个相同的个体。
即就是：同名同物。
例如： --Do you want the magazine? ---Yes，I want it.I don't want to drink the tea．It is too hot．2. one 通常用来代替上文中出现过的单数可数名词或以可数名词为中心词的词组，one的前面可以有冠词或形容词，也可以有this或that，但其前不能有物主代词。
例如：I have 1ost my pen．I’m going to buy one.I don't like this green shirt. I like the blue one. I prefer this one to that one. 3．ones是one的复数形式，常用来代替复数可数名词，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。
例如：I have a new coat and several old ones.These yellow waistcoats are so small. I want those green ones.4．that用来代替上下文中的名词，它表示与前面同类的东西。
that既可代替可数名词，又可代替不可数名词，常有后置定语，一般不指人。
例如： The price of wheat is higher than that of rice.The population of China is larger than that of Japan.5．those是that的复数形式，可用来替代可数名词的复数形式，表示特指某一范围内的人或者物。

I．替代词one和ones的用法：1．one只能替代单数名词，one的复数形式ones只能替代复数名词。
例如：My child doesn't like this book．Show her a more interesting one．2．替代词one或ones必须带有一个限定或修饰词，它们和所替代的名词中心词所指不一定是同一对象，这是替代词one或ones在用法上的一个重要特征。
例如：I don't like this book．I'd like a more interesting one．3．当替代词one或ones带有后置修饰语时，它们前面总有定冠词。
例如：Our new cassette is more expensive than the one we had before．4．当替代词one或ones在形容词比较级、最高级以及某些限定词如this，that，which 和序数词等之后，可以省略。
例如：This book is much better than that（one）．5．替代词one或ones通常不用在物主代词和名词所有格之后。
如不可说my one（s），your one（s），Peter's one（s）等等。
one或ones也不能用在own之后。
但是，如果有了形容词，one（s）可以和物主代词及名词所有格连用。
如：My cheap camera seems to be just as good as John's expensive one．6．one作替代词时，在of前面不能用the one来表示所属关系和类似概念。
代词it,one,ones,the one,that,those的用法
She would rather have the small one than the large one.
4.当有后置修饰语时，通常用the one 如：
My room is better than the one next door.

These chairs have the great advantage of being much cheaper than conventional ones.
四 代替表特指的复数名词通常用the 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?
Don't buy the expensive apples;get the cheaper ones.
1 当替代词one/ones紧跟在形容词最高级，序数词以及this/that/these/those/which/either/neither/another等限定词之后时通常可以省略。如：
I think my dog's the faster(one)
one,the one,that ,it的区别
One, the one, ones, the ones, that, those与it的指代用法近年来在高考中既是重点也是难点，区分度较高，同学们解答此类试题，要区分空格处是特指还是泛指，是单数还是复数，现将它们区别如下：①one指代上文提到的单数人的人或物，指“同一类中的一个”，表示泛指意义：即：a/an十单数可数名词。
The population problem may be the greatest one of the world today.（one=a problem）The editor-in-chief asked me to write another article for them, one about how to prevent bird flu.（one=an article）②the one 指代上文的单数可数名词，可以用形容词放在one之前修饰，one后也可以接后置定语修饰，专指“同类的那/这一个。
”表示特指的含义。
即the+单数可数名词。
The film is not as good as the one I saw yesterday.（the one=the film）Is this school the one you visited last year?（the one=the school）③ones指上文提到的复数的人或物，表示“同类中的许多”，表示泛指意义。
These apple are bigger than those ones.（ones=apples）These shoes are too small.Please get met some larger ones.(ones=shoes)④the ones指上文的复数可数名词，ones之前可以有形容词修饰。
也可以用后置定语修饰，专指“同类中的那/这一些”。
表示特指，即the+可数名词复数。
替代词one, ones, that, those, it, this, that讲解
That/ those不带前置定语，但必须有后置定语。 one/ones都可。当替换词的后置定语用所有格的of 短语或当替换词被所有格修饰时，不用one/onI like the vase better than ________________in the one / that another shop. The windows of your flat are cleaner than those _________of mine. A grandparent’s job is easier than ________of a that parent. The computers in our school are connected to the Internet while __________ in their school aren’t. those
one，that 和it比较
one 泛指=a+n. , that和it 表示特指。 that (指代可数名词)=the+n.与所指名词为同类， 但不是同一物。 it 与所指名词为同一物。 I can’t find my hat. I think I must buy one. (泛指) The hat you bought is bigger than that I bought. (同类但不同个) I can‘t find my hat. I don’ t know where I put it. ( 同一物)
That/ those用于替换有定冠词的名词；one/ones用 于替换有不定冠词的名词。
eg: The style of the building is similar to that _________of a temple. A CD player made in Japan costs more than one ________made in China.

I. it／one ／that三者均可用作代词, 指代前面提到的名词。
一般说来, it指代同名同物; one 与that则指代同名异物。
I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella）
I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella 已经丢了）
The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”）
II. one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当
于the ＋名词。
所以one所指代的名词的修饰语一般为 a／an ／some ／any; that所指代的名词的修饰语往往是the ／this ／that。
A chair made of steel is stronger than one made of wood. （该句中one可以换成a chair）

IV. one既可代替事物, 也可代替人, that只能代替事物而不能代替人。
有时可以用the one或the ones代替that或those。
The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That）
He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that）

而 that不能有前置修饰语, 但可有后置修饰语。
Cook was a strict but good captain, one who took good care of his sailors.
The water in the well is cleaner than that in the river.

one与that均无此用法。

VII. it与that均可以替代上文全句的内容或部分内容, 而one ／ones则不可以。
