下面就其使用的重点及难点,分门别类地加以总结。
1. 作人称代词,可以用来代替人、物或事；亦作非人称代词，表示时间、天气、季节、距离等。
It i s r aining c ats a nd d ogs. 雨下得很大。
It is a long way to the college. 大学距这儿很远。

The baby cried because it was hungry。
小宝贝因为饿而哭了。
3. 作形式主语英语中不定式、动名词、主语从句在作主语时，主语往往显得很长，使整个句子看上去有点头重脚轻，这时就需要借助“It”作形式上的主语，而把整个句子的主语移到句子后边去，使句子看上去平稳一些。
It is difficult to study and work at the same time.一边工作一边学习很难。
It is very clear that the elephant's l eg is round a nd tall like a tree.大象的腿跟树干一样圆而高，这点显而易见。

it五种用法归纳
it五种用法归纳好嘞，以下是为您创作的关于“it 五种用法归纳”的文案：咱们在学习英语的过程中，it 这个小小的单词可有着大大的作用呢！今天咱们就来好好归纳一下 it 的五种常见用法。
先来说说 it 用作人称代词的时候。
比如说，“It is a dog”在这儿，it就用来指代一只狗。
想象一下，你走在路上，突然看到一只毛茸茸的小狗在路边玩耍，你指着它跟朋友说：“Look! It is so cute!” 这里的 it 就是明确地指代了那只让你觉得可爱的小狗。
it 还能用来表示天气、时间、距离等。
比如说“It's sunny today” （今天阳光明媚。
）当你早上推开窗户，感受到那温暖的阳光洒在脸上，你就会自然而然地说出这句话。
又比如“It's five o'clock”（现在五点钟了。
）你看着墙上的时钟，指针指向了五，你就清楚地知道该做什么事情啦。

it 作非人称代词也很常见哦。
像“It's difficult to learn English well”（学好英语很难。
）当你为了背单词、学语法而感到头疼的时候，是不是就会有这样的感慨呢。
还有呀，it 可以用来构成强调句型“It is/was ＋被强调部分＋that/who ＋其他部分”。

高中英语it的基本用法
高中英语it的基本用法''It'' 用法及其句型和固定搭配，是高中英语语法的重点、难点，又是近几年高考的热点，因此应给予充分的重视。
初小内容归纳：一、it指代（后行）作用:1.It的基本用法是用来指代上文所提到的事物。
如橙子妈妈经常给学生用最简单的方法举例：I have a pen and I like it.2.学会区分这几组词：it, that, one, the one, ones, the ones用于指代:橙子妈妈归纳的口诀：it指代同名同物；one指代同名异物, that 指代抽象物体居多即it代替上文提及的原物(复数用they)；one指代上文提及的、泛指的可数名词单数（复数ones）；that指代上文提及的定指的可数名词单数或不可数名词（复数those）, the ones 相当于these, those。
注意：指代不明身份（例如有人在外面叫你或者敲门）或性别的人（如小baby）也用it；指代喜爱的事物或宠物也可用she / he。
A：Who''s it (knocking at the door)? B: It''s me.二、虚义it:（初中阶段的重点内容）虚义it指用作没有具体语义的主语，如表示时间、天气、距离、温度等概念的用法。
It is a good day.It cost me 10 dollars.高中内容归纳一、形式it:由于句子结构的需要，常常把it作形式主语，而把真正的主语放后置。
小伙伴们熟不熟悉！1．形式主语：不定式、动名词以及主语从句作主语时，为避免“头重脚轻”，要将真正的主语后置。
It is obvious that he will win the match. （主语从句作主语）It was worthwhile searching for his ''roots.'' （动名词作主语）It took me 10 dollars to buy the book. （不定式作主语）2．形式宾语：当不定式、动名词、that 从句作宾语，又有自己的宾语补语时，要用it 作形式宾语，而把真正的宾语后置。

高考英语语法知识之It 的用法总结1．It is + 被强调部分+ that ...该句型是强调句型。
将被强调的部分放在前面，其它部分置于that之后。
被强调部分可以是主语，宾语，状语。
强调的主语如果是人，that可以由who换用。
如果把这种句型结构划掉后，应该是一个完整无缺的句子。
这也是判断强调句型与其它从句的方法。
It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father.2．It was not until + 被强调部分+ that ...该句型也是强调句型。
主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。
It was not until she took off her dark glasses that I realized she was a famous film star.= Not until she took off her dark glasses did I realize she was a famous film star.= I didn’t realize she was a famous film star until she took off her dark glasses.3．It is clear ( obvious, true, possible,certain....) that .....该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。
It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear.4. It is important ( necessary, right, strange, natural...) that ...由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。
It is important that we (should) learn English well. It is necessary that he (should) remember these words.5. It is said (reported, learned....) that ...该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。
该结构常译为＂据说（据报道，据悉．．．）＂。
It is said that he has come to Beijing.6. It is suggested ( ordered ... ) that ...主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。
常译为＂据建议；有命令．．It is suggested that the meeting ( should ) be put off.It was ordered that we ( should ) arrive there in two hours.7. It is a pity ( a shame ... ) that ...该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。
没有这种意义时，则不用虚拟语气。
It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill.8. It is time ( about time ,high time ) that ...该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。
常译为＂是（正是）．．．的时侯．．．＂。
It is time that children should go to bed. = It is time that children went to bed.9. It is the first ( second ... ) time that ...该句型中的that 从句不用虚拟语气，而用完成时态。
至于用什么完成时态，由主句的谓语动词的时态决定。
如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。
该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人第几次做某事了＂。
It is the first time I have been here. = This is the first time I have been here.10 It is the +形容词最高级+ 名词+ that + …..该句型中的that 从句不用虚拟语气，而用完成时态。
至于用什么完成时态，由主句的谓语动词的时态决定。
如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。
该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人做过的最…的事情＂。
This is the best film that I have ever seen . That was the worst song that he had heard .11. It is .... since ...该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。
主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。
如果主句是一般过去时，从句则用过去完成时。
It is ( has been ) 5 years since his father died.12. It is ... when ...该句型中的when 引导的是一个时间状语从句，主句中的it 指时间，表语由具体的时间充当。
常译为＂当．．．的时候，是．．．＂。

It looks ( seems ) as if ...该句型中it无意义。
as if 引导一个状语从句。
常译为，＂看起来好象．．．＂如果与事实不相符合，则用虚拟语气．It looks as if he is ill.It looks as if he were ill. It seemed as if he were dying.16. It takes/costs sb. ... to do sth.该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。
常译为＂做．．．要花费某人．．．＂。
It took thousands of people many years to build the Great Wall.注意：当主语和表语都是不定式时，不能用it 作形式主语代替动词不定式。
To see is to believe . To respect others is to be respected .17. It is kind ( of sb. ) to do sth.该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由of引起，主句中的形容词必须是能表示逻辑主语特征的形容词。
常见的有：bad , brave , careless, clever , cruel , foolish , good （好心的）, honest , horrible , kind , lazy , modest , naughty , nice（有教养的）, polite, rude , silly , stupid , wise , wrong（错误的）等。
