(一)下面就one在中学英语中的常见用法作简要归纳：一、one作人称代词可以笼统地指任何人、某一伙人中的一个人或说话人。
当one笼统地指任何人时，其用法相当于you指代任何人。
在书面语中，one比you更常见。
1．One can\'t succeed without working hard．一个人不努力工作是不会成功的。
2．He is the one who never troubles about personal interests．他是一个从不计较个人利益的人。
二、one作为人称代词，其所有格为one\'s，反身代词为oneself。
如果one用于句首，后面再用代词one，oneself或one\'s，可以用he，him，himself或his代替。

英语高考专题复习讲与练（8）替代词it, that, one, which, so的用法比较英语的代替现象比汉语普遍，使用代词的场合比汉语多。
大多数句子中均用代词代替上文谈到的人、事物或情况，避免了对较多名词、冠词的反复使用，这样大大简化了句子。
最常用于表示替代关系的词语有it, that, which, one, so等，近几年高考试题中均对这些词的用法进行了考查，可见这几个替代词的用法非常重要。
下面归纳它们表示替代时的不同用法。
一、it的用法1、it指代上文所提事物的本身（it表时间、强调等的用法此处不阐明），如果所代替的事物为复数，则应该用th ey或th em表示。
2、it也可以用来代替上文所提到的一件事。

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。
Open the drawer on the left, the one with a key in it. 打开左边的抽屉，上面有钥匙的那个。

those的用法和区别it代指前面提到的事物，没有特定的限定；that代指前面提到的特定的事物，通常与the连用；the one代指前面提到的特定的事物，强调的是单个事物。
如：I saw a bird in the tree。

它在唱歌。
I saw a bird in the tree。
That bird was singing.我在树上看到了一只鸟。
那只鸟在唱歌。
I saw two birds in the tree。
The one on the left was singing.我在树上看到了两只鸟。
左边那只在唱歌。
⑷.that和those区别：that代指离说话人较近的事物，通常用于单数形式；those代指离说话人较远的事物，通常用于复数形式。
如：That book on the desk is XXX.那本书在桌子上是我的。

人称代词的主格在句子中作主语或表语
人称代词的主格在句子中作主语或表语，宾格作动词或介词的宾语，也可作表语使用。
如：We all like him.(we作主语，him作宾语)—Who is it?—It's I/me.(it作主语，I/me作表语) 当句中三种人称单数并列时一般顺序是you, he and I(即二、三、一)；复数并列时顺序是we, you and they。
(2)it的用法①代替前面提到过的事物。
如：This is a watch. It is new.这是一块手表，它是新的。
②指时间、天气、距离等。
如：—How's the weather today？今天天气怎样？—It's sunny.天气晴朗。
It's eight o'clock in the evening. 现在是晚上8点钟。

如：____hard for me________the homework on time.对我而言，按时完成作业有困难。
We think it helpful________a walk after supper.我们认为晚饭后散步很有益。
________him three days to finish reading the book.他花了三天时间读完了那本书。
形容词性物主代词不能单独使用，用于名词前作定语，相当于形容词的作用；名词性物主代词单独使用，相当于名词的作用。
名词性物主代词＝形容词性物主代词＋名词。
如：This is his computer. ＝This computer is his.2.用法(1)反身代词在句子中用作宾语和表语(不能单独用作主语)，和句子中的主语相呼应，表示主语动作的承受者或表现的特征是自己本身。
如：The girl is too young to look after ______.这个女孩太小，不能照顾自己。

![区别+例题代词it__one__that和those用法说明[1]](https://img.taocdn.com/s3/m/0c2c97ad3968011ca30091b8.png)
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 it that的区别是什么
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。
代词it、one、that的用法
代词that, one, the one, it的用法区别它们三词均作代词用，指代前文提到的名词。
但是it所指是同名同物，one和that所指是同名异物①that是特指，代替前面提到的不可数名词或单数可数名词。
代指前面提及的同类而非同一物，其复数用those，后面一般有后置定语。
The weather in Kunming is better than that in Wuhan.The population of China is larger than that of any other country in theworld.②one是泛指，指代前面提到的同类人或物（可数名词）中的一个，其复数用ones，前面一般有定语。
