指的是同类事物中的另一样东西，即同类异物。

如：The library of our school is bigger than that of yours.(that代替的是另一个图书馆。

)4．One 和that 在代替可数名词时，如果没有前置定语只有后置定语时， the one 和that可互换。

但该名词如有前置定语，则只能用the one,而不能用that。

例如：①I will take the seat next to the one(=that)by the window.我就坐窗口的那个座位旁边。

代词it, one, that和those用法说明为了避免重复出现前面已经出现的名词，常用it, one, that, those来替代。

这几个替代词是高考中的一个常考点。

现将各个替代词的用法归纳如下：用法说明一：it和that都替代“the+单数名词(可数或不可数)”，都是特指，都可替代可数和不可数名词，但it指前面提到的“同一”事物，而that是指前面提到的“同类”事物。

如：My father bought me a pen and I like it very much.我父亲给我买了一支钢笔，我非常喜欢它。

(it替代the pen，指前面提到的父亲给我买的那支钢笔)This dictionary is more useful than that (=the one)I bought yesterday.这本词典比我昨天买的更有用。

(that替代the dictionary，与前面的this dictionary是同类)用法说明二：one替代“a＋单数可数名词”，表示泛指；其复数形式ones替代泛指的复数名词。

特指的the one相当于that，替代“the+单数名词”；the one的复数形式the ones，替代“the+复数名词”，在口语中也常用those代替。

当后面有of短语时，多用that 或those；当有前置修饰语时，只能用one(s)。

另外，one(s), the one(s), those 都只能替代可数名词。

如：Radios are useful for me to learn English. I’d like to buy one.收音机对我学英语很有用，我想买一台。

(one替代a radio，是泛指收音机这类东西中的一台) We still have shortcomings，and they are very big ones too.我们还有缺点，而且是很大的缺点。

one表示泛指，that和it表示特指。

that与所指名词为同类，但不是同一个，而it与所指名词为同一个。

one it that的区别一、one/ it/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。

例句：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myumbrella已经丢了)The umbrella you bought is cheaper than that I bought.(替代词that在该句中特指“theumbrella I bought”,以区别“the umbrella you bought”)二、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。

例句：A chair made of steel is stronger than one made of wood.(该句中one可以换成achair)The water in the cup is hotter than that in the pot.(该句中that可以换成 thewater)三、one只能代替可数名词单数,代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数,代替可数名词复数时用those。

例句：I like this pen more than that one.(one代替可数名词单数pen)There were a few young people and some older ones in thehouse.(ones代替可数名词复数people)Mary's handwriting is far better than that of Peter.(that代替不可数名词handwriting)These pictures are more beautiful than those.(those代替可数名词复数 pictures)四、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。

英语中代词（that, it，one等的区别）代词one, it，that的用法在历届高考题中出现的频率较高，是高考的热点之一。

笔者结合自己的教学实践在此谈谈它们的一些具体用法，希望能对同学们有一定的帮助。

笼统地说，it指代的是同类同物，that指代的是同类异物，one指的是上下文中提到的同类事物中的一个。

以下是具体的区别：1.one, it, that常常用来代替或避免重复某个名词。

例如：①I'm looking for a flat. I'd really like one with a garden.②-Where did you find your watch? - I find it in our classroom.③The population of China is larger than that of any other country.2.one可指人或物，只替代单数可数名词，复数用ones. One是泛指，但有限定修饰语，如the, this, that…修饰就变成了特指。

如：①One must do one's duty.②Mary has a red pencil and Jane has a blue one.③The new designs are much better than the old ones.3.that只指物，不指人，可替代可数名词或不可数名词，具有“特指”性质。

指的是同类事物中的另一样东西，即同类异物。

如：The library of our school is bigger than that of yours.(that代替的是另一个图书馆。

)4．One 和that 在代替可数名词时，如果没有前置定语只有后置定语时，the one 和that可互换。

但该名词如有前置定语，则只能用the one,而不能用that。

简单的说，就是one相当于an/a+名词，that相当于the+名词。

it/one/that的用法和区别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）The water in the cup is hotter than that in the pot. （该句中that 可以换成 the water）III. one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。

I like this pen more than that one. （one代替可数名词单数pen）There were a few young people and some older ones in the house. （ones 代替可数名词复数people）Mary's handwriting is far better than that of Peter. （that代替不可数名词 handwriting）These pictures are more beautiful than those. （those代替可数名词复数 pictures）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。
