its与it's怎么区别，怎么用的。比如its name和it's name

区别：

一、用法不同。

it 指代上文提到的同一事物。（同类同物）

The book is mine It’s very interesting

这本书是我的，它很有趣。

that常用于比较结构中，代替前面提到的名词，以避免重复。

The weather in Beijing is colder than that in Guangzhou in winter

在冬天北京的天气比广州冷。

一、指示人物不同。

this和that是指示代词，it是人称代词。

二、回答不同。

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

Is this a notebook

这是笔记本吗

Yes, it is

是的，它是。

扩展资料：

“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。现将that的用法总结归纳如下：

第一、that 用作形容词（后接复数名词时用those）。

它用来指已被提到的人或物；也可表对比，指两个中较远的那个。

What about that book you borrowed from me last month？

请注意，that有时候在句子中具有喜欢或轻蔑等感情色彩。

that little son of his 他那个小宝贝儿子

That George！乔治那家伙！（含有轻蔑语气）

第二、that 用作代词。

1、 that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。

That is what he told me

这是他告诉我的事情。

2 that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）

请注意，that 在定语从句中作宾语时通常可省略。

The books (that) I sent you will help you in your studies

我寄给你的书将有助于你的学习。

第三、that 用作连词，引导名词性从句,状语从句和强调句。

好的,我给你例句：

Mr Wang is very kindHe gives us lots of help

==MrWang gives us a lot of help,and THAT is very kind of him

that指代前面提到的MrWang gives us a lot of help

==It is very kind of MrWang to give us a lot of help

It(形式主语) is very kind （表语）of MrWang to give us a lot of help（从of到最后都是真正主语）------it的使用是为了使句子变得平衡

its

name是：它的名字。it's

name是：它是名字。

its与it's的区别为指代不同、用法不同、词性不同，用法如下：

一、指代不同

1、its：(指事物、动物或婴儿)它的，他的，她的。

2、it's：it

is

的常用口语形式它是。

二、用法不同

1、its：its既可以作为形容词性物主代词，指"它的"，后接名词，也可以作为名词性物主代词"它的"，单独使用，后面不接名词。

2、it's：it's后面接表语，一起构成系表结构，用it作人称代词，可替代无生命的东西或事情，在性别不详或无所谓时，也可指代人，尤其是指婴儿。it作主语时，可指自然现象、季节、时间、距离、环境等。

三、词性不同

1、its：its是形容词性物主代词。

2、it's：it's是主语和系动词的缩写行式。

1、It除了代替人和物以外,可以作形式主语而真正的主语(不定式、动名词或从句)则放于谓语或表语之后如：It is nor easy to finish the work in two days然而有少数表语之后接动名词作真正的主语这些表语是：无助(no help)、无用(no use)、没好处(no good)；工作(hard work)、费时(a waste of time)、危险(a danger)如：A、It is no use crying over spilt milkB、It is a waste of time waiting for him． 2、It还可以作形式宾语通常下列动词后面可接it作形式宾语：2f2tcjm(find,feel,think,take,consider,judge,make)如：I think it no use arguing with him3、It用于强调句式要强调句子的某一部分(主语、宾语、状语),可以把it当作先行词这种句子的结构是：It is(was)+ 被强调部分+that(who)+句子的其余部分如：A、It is Professor Lin who teaches us English(强调主语) B、It was in Shanghai that l saw the film(强调状语) 非谓语动词和“it的用法”在语法里运用比较多“找规律,巧记固定搭配”是学习语法比较有用的方法,在学习当中可以继续总结,找出更有用的规律

通常用it 做形式主语，将不定式和动名词置于谓语后面，特别是主语较长时，或在一些习惯用法中。

1） 谓语是系表结构（be + 形容词 / 名词）时，常将不定式后置，构成句型 “it + be + 表语（形容词 / 名词）+ 不定式”。

例 1 It is my duty to care for that patient

照料那位病人是我的职责。（做主语的不定式to care for that patient 后置，it 为形式主语）

例 2 It is not an easy thing to master a foreign language

掌握一门外语不是件容易的事。

例 3 It isn’t right to speak ill of someone behind his back

在别人背后说坏话是不对的。

2） 当谓语是 take，make，pay，cost ，require， feel，need 等动词时，或者是与情绪有关的动词 delight，amuse，excite，annoy，irritate 等时，习惯上常用 it 做形式主语，并将不定式后置。

例 1 It takes only ten minutes to get there

到那儿只需十分钟。

例 2 It pays to be honest

诚实是不会吃亏的。

例 3 It feels good to stay away from the crowded city

能远离拥挤的城市，感觉真不错。

例 4 It annoyed her to see someone spit on the ground

看见有人随地吐痰让她很生气。

3） 同不定式一样，动名词也可用于“it + be + 表语 + 动名词”句型中，二者的区别可参见10．2．2 中1）的论述。下面两组句子没有多大差异。

例 1 A） It is a waste of time to argue with him

B） It is a waste of time arguing with him

和他争辩是浪费时间。

例 2 A） It is worthwhile to discuss this again

B） It is worthwhile discussing this again

这一点值得在讨论一下。

4） 但表语是（of）no use，not any use，not the slightest use， no good， not much good，fun等时，常用动名词（不用不定式）做主语并后置，用 it 做形式主语。

例如 It’s no use crying over spilt milk

覆水难收。

5） 动名词还可在 there be 句型中做主语（不能用不定式），常见形式为 “there is no + 动名词”或 “there is no / any + 名词 + 动名词”。

例 1 There is no denying the fact

事实无可否定。

例 2 There isn’t any use trying again

再试也没用

“It” 用法及其句型和固定搭配，是英语语法的重点、难点，又是近几年考试的热点，因此在复习中应给予足够的重视。现将it用法归纳如下：

一、It用作实词

表达以下概念:指代前文提到的事物，前文中的this, that；替代前文中的内容；指代一位性别不明的小孩或未知的人；指代未指明但谈话双方都知道的那件事；指代时间、天气、气候、距离等自然现象。

二、It用作形式主语

替代作主语的从句、动词不定式、动名词，而把真正作主语的从句、动词不定式、动名词置于句尾。

It 作形式主语的常见句型：1 代作主语的动词不定式，其句型为（1）It be adj (for sb) to do sth

（2）It be adj of sb to do sth

（3）It替代作主语的动名词的常见句型：

It’s no good/use doing…

It’s (well)worth doing…

It’s (well)worth one’s while doing/to do It’s (well)worth while doing/ to do

2 It替代作主语的从句常见句型

（1）It is + noun +从句

（2）It is adj +clause

It’s surprising that… (should)………竟然……

It’s a pity/shame that…(should)………竟然…

（3）It verb sb + clause= It is v-ing + clause

It+surprise/delight/interest/disappoint/worry/disturb/annoy/amaze/bother/concern/frighten/please/anger sb that…

（4）It verb (to sb) that…= sb/sth verb to do

(verb = appear, seem, come about, emerge, follow, chance, happen, occur, transpire, turn out , work out)

（5）It is v-ed that…=sb/sth is to do

(verb=say, report, think, believe, hope, expect, agree, accept, decide, determine, intend, plan, understand, know）

四、It 作形式宾语

用来替代作宾语的从句、动词不定式、动名词，而把真正作宾语的从句、动词不定式、动名词置于句尾。

It 作形式宾语的常见句型：

1 verb+ it+ adj/noun (for/of) to do/clause (verb=think, believe, suppose, consider, feel, make, keep…)

五、强调句型

It is/was+被强调部分+ that(who)… 强调句型用来强调谓语动词以外的任何句子成分。当被强调部分是人时也可以用who。

在使用强调句型时需注意以下几点：

1 请注意强调句型的特殊疑问句

2 在强调原因状语从句时，只能强调由because所引导的从句。

3 在强调not … until结构时必须把not与until一起放到被强调的位置上。

4 注意强调句型与定语从句的区别。

六、It 常用的固定搭配

1 make it

(1)在口语当中相当于succeed,表示：成功、做到、说定、赶上、及时到达 。

it的所有用法总结如下：

I．It 作形式主语的句型

①It + be + adj(kind , wise , careless, clever…) + of sb to do sth

Eg: It is wise of him to make such a decision他做出这样的决定是明智的。

②It + be + adj(easy , safe , common , normal …)+ for sb to do sth

该句型中adj若为important, necessary, natural, possible, strange, vital, essential等可改为从句,从句用should+动词原形。

Eg: It’s very dangerous for children to play with fire

It is important for us to learn English well (= It is important that we (should) learn English well)

③ It + be +V-ed(reported,believed, said, suggested…)+ that 从句

该句型中：⑴若V-ed为reported, believed, said等常译为“据报道”，“据认为”，“据说”。⑵若V-ed为suggested, ordered, demanded, insisted等表示“建议”,“命令”的词，从句要用虚拟语气(should)+动词原形。

Eg: It is suggested that the book (should) be revised

It’s said that Tom has been back from abroad (=Tom is said to have been back from abroad)

④ It + be + n (a pity, a shame, a fact , good news…)+ that 从句:

该句型中，从句一般用(should) + 动词原形，表示出乎意料，常译为＂竟然＂。

Eg: It is a pity that such a thing ( should ) happen in your class 这种事竟然发生在你们班上，真是遗憾！

⑤ It is useless/no use/no good /pleasure+ doing sth

此句型中的it是形式主语, 其后的动名词短语是真正的主语,译为“做…没有用”。

Eg : It ‘s useless arguing with him further // It’s no use talking with him, because he won’t listen

⑥ It takes sb to do sth

该句型中it是形式主语，真正的宾语是to do sth，常译为＂做……要花费某人……＂。

Eg: It took thousands of people many years to build the Great Wall

II．It 作形式宾语的句型

1sb find/ believe/ think/ feel/ consider/ make + it +n/adj +to do或从句

该句型中的it 作形式宾语。为了记忆方便我们可称该句型为“6123结构”。6 指主句中常用的动词：think, believe, make, find, consider, feel；1 指的是形式宾语 it；2 指的是宾补的两种形式：形容词或名词；3 指的是真正宾语的三种形式：不定式短语，动名词短语或that引导的宾语从句。

Eg: We think it our duty to clean our classroom every day

He felt it important learning English well

They found it difficult that they would finish their work in two days

2主语＋hate / dislike / love / like ＋it ＋when－从句

Eg: I hate it when people speak with their mouths full

3 主语＋appreciate ＋it ＋if－从句

Eg: I really appreciate it if you could help me with my math

4 sb depend on/count on/rely on/see to(负责，确保)/ answer for it that…

Eg: You may rely on it that he won’t be late

You must see to it that the doors are locked before you leave the lab

5 sb take it for granted that… 认为……是理所当然的

Eg: I take it for granted that he will succeed

IIIIt 引导的时间句型

⑴ It + is/has been+ 时间段+ since引导的时间状语从句:

该句型中从句一般用过去时态，句意为“自从以来已多久了”

Eg : It is 5 minutes since the bus left 公汽开走已有5分钟了

⑵ It + be（will/was）+ 时间段 + before引导的时间状语从句:

该句型中，主句谓语动词be若为肯定式，意为“过多久才”；若为否定式时，意为“没过多久就”。

Eg : It will be long/ 3 hours before he comes back要过三个小时他才会回来

It was 3 hours before he came back 过了三个小时他才回来

⑶ It + be + 时间点+ when引导的时间状语从句

这个句型中, it 代指时间，表示时间点的词前没有介词。

Eg : It will be Monday when he comes back 他周一的时候回来

It was Monday when he came back 他周一回来的

对比：It was on Monday that he came back (强调句)

⑷ It + is (about/high) time + (that) sb did/should dosth

意为“该是某人做…的时候了”， about/high是用于加强语气，that从句用should或动词一般过去时表虚拟。

亦可转换成 It + is+ time +(for sb )to do sth

Eg : It’s (high/about) time (that) we handed in/should hand in our homework

⑸ It / This / That +is+ the first(second …) time + that sb has done sth:

意为“这是某人第…次做…”，注意time前有序数词，主句是 is 时 ，从句要用现在完成时；如果主句用was ，则从句须用过去完成时。 Eg : It is the third time that I have seen the film

That was the second time that I have been there

IV．It 引导的强调句

强调句形式：It + is/was +被强调的部分+ that/who从句

Eg: It was last week that I met an old friend in the street // It was because he was ill that he didn't come to school yesterday

(强调原因状语从句时，只能强调由because所引导的从句)

判断方法：将It is/was和that去掉，若该句是一个完整无缺的句子即为强调句

常考考点：

①强调句型中的主谓一致Eg: It is you，rather than he，that are to blame for the accident．

②插入从句的强调句型 Eg: It was in the restaurant where we had dinner last Sunday that you left your wallet．

③强调句型的一般疑问句、特殊疑问句形式

一般疑问句：Is / Was it + 被强调部分+ that + 句子其余部分 Eg: Was it in 1933 that the Second World War broke out

特殊疑问句：疑问词+ be + it + that + 句子其余部分Eg: When was it that he changed his mind to take part in the activity？

④强调句型用于名词性从句, 尤其注意要使用陈述语序。

Eg: I don’t know when it was that he changed his mind to take part in the activity？

⑤not until用于强调句型 It is / was not until ＋被强调部分＋ that ＋其他部分

Eg : It was not until midnight that she went back home

此句型只用until，不用till。但如果不是强调句型，till和until可通用。因为句型中It is / was not已经是否定句了，that后面的从句要用肯定句。

V．It其他常见用法：

It looks / appears as if 看起来好像……It looks as if she is ill

It seems that 似乎…… It seems that he will be back in a few days

It turns out that 原来是…… It turned out that the beautiful woman was a thief

It occurs to/strikes sb that… 突然想到……It occurred to me that I hadn’t locked the door

It happened that 碰巧…… It happened that he met his teacher in the street

It doesn’t matter whether/if…无论是…没关系 It doesn’t matter whether he will come or not

It is no wonder that 难怪… He works so hard It’s no wonder he could pass the exam

How did it come about that … “……怎么发生的？” How did it come about that his bike was thrown into the river

It all depends/that all depends那得看情况

It's up to sb由……决定，由……负责，取决于……

as it is (1)事实上，实际情况是……; (2)照原样

make it成功、做到、说定

Believe it or not信不信由你

Get it 明白了

it is neccessary for us to

i think it的it是形式宾语 形式主语和形式宾语通常用在不定式中，用it代替。

形式主语it +谓语或宾语+ adj +to do sth

如It is useful to study English。在这个句中真正的主语是后面的to do形式，it 叫形式主语。

形式宾语的句子 主语 谓语或宾语 it adj to do sth

如I think it is intresesting to dance 。真正的宾语是to do形式，it叫形式宾语。

形式主语和宾语的使用都是为了简化语句，让别人一目了然。之所以用it 代替是 避免头重脚轻。

“it”作形式宾语时的几种特殊结构

在英语中，当动词不定式、动名词或从句在句中充当宾语且其后又带有宾语补足语时，习惯上要在宾语补足语前使用一个没有具体意义的形式宾语it，而将真正的宾语移到补足语的后面，构成“动词＋it＋宾语补足语＋不定式（动名词或从句）”结构。如：

She felt it her duty to take good care of them

她感到好好照顾他们是她的责任。

I think it no good going there now

我认为现在去那里没有好处。

The headmaster has made it clear that the school meeting will not be put off

校长说得很清楚校会不会推迟。

但我们常会碰到it用作形式宾语时之后没有形容词或名词作宾语补足语的情况，这一点在近几年高考试题中经常涉及，需引起同学们的注意。

I hate_____ when people talk with their mouths full (NMET 1998)

A it B that C these D them (答案为: A)

我讨厌人们一边吃饭一边说话。

I like _____ in the autumn when the weather is clear and bright (全国卷 2004)

A this B that C it D one (答案为: C)

我喜欢秋天晴朗的天气。

以上这两道高考题中，it用作形式宾语，它的真正的宾语则是由when引导的从句。“it”的这种特殊用法常出现在以下几种结构中。

A 动词＋it＋when / if 从句。常见于appreciate, enjoy, like, dislike, love, hate, prefer等少数动词之后。

We would much appreciate it if you could do us that favour

要是你们能帮我们这个忙，我们将非常感激。

I'd prefer it if I didn't have to finish the work

要是我不必完成那项工作，那就太好了。

B 动词+ it + that从句。常见于like, take, have, put等少数动词之后（it相当于that从句的同位语）。

I take it that they will succeed sooner or later

我认为他们迟早会成功的。

The newspapers have it that some Japanese firms have gone bankrupt

报上说一些日本商号破产了。

Rumor has it that Mary is getting married 谣传玛丽快结婚了。

I take it that you have been out 我以为你一直出门在外。

Let me come and stay You can put it that it was arranged before

就让我来呆在这儿吧，你就说原先就是这样安排的。

C 动词 + it + 介词短语 + that从句。常见于bring it to one's attention;

owe it to sb; take it for granted 等结构中。

I owe it to you that I finished my work in time

多亏有你我才及时完成了工作。

Don't take it for granted that they will support you

不要想当然地认为他们会支持你。

D 动词 + 介词(短语) + it + that从句。常见于answer for, depend on, rely on, insist on, look to, see to, stick to 等结构中。

I'll see to it that everything is ready in time

我将负责按时做好一切准备。

You may depend on it that Tom will help you with your English

你放心，汤姆会帮助你学英语的。

I’m counting on it that you will come 我指望着你会来。

E 动词+ it +过去分词+从句。常见于几个可以带过去分词作宾语补足语的动词之后。

I heard it said that that factory was founded in 1995

我听说那家工厂是1995年创建的。

They haven't made it known where the meeting is to take place

他们没有宣布会议在哪里召开。

“It”作形式主语和宾语

It作形式主语和形式宾语用法，是中学阶段英语学习的主要语法项目之一。纵观历届高考题，无论是单项选择，还是完行填空，it用法始终是反复考查的重、热点之一。现将it在特殊句型中作形式主语和形式宾语用法，进行如下归纳分析，以供学习参考。

一、 It 用作形式主语

当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。此时it只起先行引导作用，本身无词义。

eg It is wrong to tell a lie

(说谎是错误的。) 〔It为to tell a lie的形式主语〕

It is no use arguing about it

(争吵是没用的。) 〔It为arguing about it的形式主语〕

It is uncertain who will come

(谁要来还不确定。) 〔It为who will come的形式主语〕

It 作形式主语的常见句型：

① It + be + 形容词 + to do sth / doing / that …

eg It is very important to learn a foreign language

(学一门外语非常重要。)

It is useless crying over the spilt milk

(覆水难收。)

It was really surprising that she married a man like that

(她嫁给那样的男士真让人惊讶。)

② It + be +名词词组 + doing / that …

eg It is no good telling lies

(撒谎没好处。)

It is a pity that you didn’t go to see the film yesterday

(你昨天没看成那部**真遗憾。)

It is a truth that there would be no new China without the Communist Party

(没有***就没有新中国，这是毋庸质疑的。)

③ It + be + 过去分词 + that …

该句型常见动词有：say, hope, think, suppose, expect, report, know, believe, decide, etc

eg It is said that they have invented a new type of computer

(据说他们发明了一种新型电脑。)

It is believed that China will become one of the strongest countries in the world

(大家都相信中国将会步入世界强国之列。)

It was reported that more than 170 thousand people died in the 2004 tsunami

(据报道，至少有十七万人在2004年那场海啸中丧生。)

④ It + seems / appears / happens等不及物动词 + that …

eg It seems that he enjoys pop songs very much

(似乎他非常喜欢流行歌曲。)

It appears that Tom might change his mind

(看来汤姆可能会改变主意。)

⑤ 若句子是疑问形式，就只能用it作形式主语。

eg Does it matter much that they won’t come tomorrow

(他们明天不来很重要吗？)

Is it true that he will go abroad next week

(他下周出国是真的吗？)

⑥ It + takes + (sb) + some time + to do sth

这是一个表示“（某人）花多少时间干某事”的句型，其中it是形式主语，代替后面的不定式（to do sth），句型中的sb也可以省略。

eg It took me some time to read the reading materials

(我花了一些时间才读完那段阅读材料。)

It took him fourteen hours to go to New Zealand from Shanghai by plane

(从上海乘飞机去新西兰花了他14小时。)

How long does it take you to go to Beijing from Qingdao by train

(从青岛坐火车到北京一般要花多久时间？)

I am not sure, but I think it takes at least nine hours to get there

(我不能肯定，但估计至少要九个钟头才能到那儿。)

二、It 用作形式宾语

当不定式（短语）、动名词（短语）或从句在某个句子中作宾语时，为保持句子结构平衡，避免句式结构的混乱，常用it作形式宾语，而将真正的宾语放在句尾。此时it仍只起先行引导作用，本身无词义。

下列四种情况须用it 作形式宾语：

① 当不定式（短语）、动名词（短语）或从句在复合宾语结构中作某些动词的宾语时（如think, make, find, consider, feel, suppose等）；

eg They found it pleasant that they worked with us Chinese

（他们发现与我们中国人一起工作很愉快。）

I don’t feel it difficult to understand the Special English

（我觉得理解英语特别节目并不难。）

He makes it a rule never to borrow money

（他立志决不向别人借钱。）

I think it no need talking about it with them

（我认为没必要跟他们谈。）

② 某些表示“喜、怒、哀、乐”的动词，如like, enjoy, love, hate等，往往不能直接接宾语从句；

eg I don’t like it that he’s so lazy

（我不喜欢他那么懒惰。）

I hate it when my mother asks me to eat eggs

（我讨厌母亲要我吃鸡蛋。）

③ that引导的宾语从句不能直接作介词的宾语；

eg You may depend on it that we shall always help you

（尽管放心，我们会随时帮你的。）

Would you see to it that she gets home early

（你负责保证她早到家，好吗？）

He insisted on it that he was innocent

（他坚持说自己是无辜的。）

④ 由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。

eg I leave it to your own judgement whether you should do it

（我让你自己判断这事是否该做。）

We owe it to you that there wasn’t a serious accident

（多亏了你才没有发生严重事故。）
