it和one作代词的区别

(1)this和that是指示代词,it是人称代词

(2)距离说话人近的人或物用this,距离说话人远的人或物用that如：

This is a flower这是一朵花(近处)

That is a tree那是一棵树(远处)

(3)放在一起的两样东西,先说this,后说that如：

This is a penThat is a pencil这是一支钢笔那是一支铅笔

(4)向别人介绍某人时说This is…,不说That is…如：

This is HelenHelen,this is Tom这是海伦,海伦,这是汤姆

(5)This is 不能缩写,而That is可以缩写如：

(6)打电话时,介绍自己用this,询问对方用that如：

—Hello!Is that Miss Green喂,是格林**吗

—Yes,this isWho’s that是的,我是,你是谁

注意：虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说：I am…,Are you…/Who are you

(7)在回答this或that作主语的疑问句时,要用it代替this或that如：

①—Is this a notebook这是笔记本吗

—Yes,it is是的,它是

②—What’s that那是什么

需要注意的是 定语从句 代替人 只有that可以用

it不能代替人 只能代替物 或者动物

“one”和“that”在做代词时有什么区别？

one 指代单数名词,而上句中weather（天气）是不可数名词,所以不能用one代替that that 指代不可数名词或者指代上文中提到的情况that指代的是“同名异物” it 指代单数名词或者不可数名词,指代“同名同物” 1it指前面提到过的问题本身 egI bought a penIt's a good pen 2that特制前面提到的名词,that和被代替的名词并非指同一事物,而是同类事物多用于事物的比较,避免重复 3one用于泛指前面提到过的名词 egYour pen is goodI want to buy one 4that只能代替事物,不能代替人 one可以代替事物,也可以代替人 在口语中it也可以指人 5it可用作无人称代词,指时间,自然现象（天气,气候,明暗等）,距离,量度,价值etc

it和the one作代词区别

1 it是代指原物，知道性别时不能代指人，不能作定语从句先行词。 the one可以代人，也可以代物，常作定语从句先行词。 2 代物时： one 泛指，it表示特指。one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。 I can't find my hat I think I must buy one （不定） 我找不到我的帽子了。我想我该去买一顶。 The hat you bought is bigger than the one I bought （同类但不同个）你买的那顶帽子比我买的大。 I can't find my hat I don't know where I put it （同一物）我找不到我的帽子。我不知道我把它放在哪了。

it,that,one作代词的区别

可数单数用one替，ones替代复数词。 不定冠词后加one，one前一般有定语。 替代若系本身物，it 替单 they 代复。 比较句中替代词，不可数名词that替。 最高级及序数词后，替代词常常被略去。 复数名词替代词，ones 与 those 均用之， 特指 ones 加定冠，those 之前无冠词。 One(s) 的定语多在前，those 的定语必后置。 是复制的 但这个总结的真的很好

it one that 作为代词的用法有什么区别

1one, 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 2one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：One must do one's duty 3that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。 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。 5．That的复数形式those代替可数名词的复数。可指人或物，一般后面跟修饰语。如： ①Today's cellphones are smaller than those(=the ones)used in the past 6the one(ones)或 that ,those 指代某一名词做定语从句的先行词时，其关系代词which在that之后，which不能省略，而在the one、ones 之后,which可省略。如：Their problem today is somewhat similar to that which they faced many years ago 7代替不可数名词时，应该用that。如：The equipment is different from that 8it代替上文所提到的名词时，是指同类事物中的同一样东西，即同类事物。如： I have lost my pen I'm looking for it 9it和that可代替前面整个句子的意思，而one却不能；that可引导一个限定性定语从句，代替某个先行词（单复数名词均可），it和one则不能；it可代替不定式、动名词或从句，用作形式主语或形式宾语，也可用于强调句型中，而one和that则不能。
