it用法及练习附答案

It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。其考查方式多通过“语法填空”进行，偶尔也出现在“短文改错”和“完形填空”中。
一、it 作人称代词的用法
1. 指事物作为人称代词，it 可以除人以外的一切事物或动物。如：
I dropped my watch and it broke.
It’s hard work, but I enjoy it.
“Where is the dog?”“It’s in the bedroom. ”
2. 指人it 指人主要用于指不性别不明的婴儿或用于确认某人的身份。如：
Is it a boy or a girl?
There is a knock on the door. It must be the postman.
【说明】在答语中，常用来指本人，如说It’s me。
3. 代替某些代词
代词it 还可用于代替指示代词this, that 以及复合不定代词something, anything, nothing等。如：“What’s this?”“It’s a new machine. ”
Nothing is wrong, is it?
二、it 作非人称代词的用法
1. 基本用法：主要用于指时间、距离、价值、天气、气候及温度等自然现象。如：
It’s too late to go there now.
It rained all day yesterday.
It can get very hot here.
2. 用于某些句型：
It’s time for sb to do sth. 某人该干某事了。
It’s (about / high) time + that-从句. 某人该做某事了。
(从句谓语用过去式，有时也用“should+动词原形”)

It’s + 时间段+ since-从句. 自从……有一段时间了。
It’s + 时间段+ before-从句. 过多长的时间才……
It’s not until........that.......直到......才.....
三、it用作形式主语
1. 基本用法：当不定式、动名词、从句等复杂成分用作句子主语时，为保持句子平衡，通常把真正的主语放在句末，而在句首使用形式主语it。如：
It’s very important to remember this.
It’s hard work climbing mountains.
It’s unknown when he will come.
2. 用作形式主语的的重要句型
(1) It + be + adj. for (of) sb to do sth 某人做某事……
It is hard for him to make up his mind. （介词for表示对象，意为“对……来说”）

(2) It takes sb + 时间段+ to do sth. 某人做某事花了……时间
(3) It is up to sb to do sth. 该由某人做某事
(4) it look (seem, appear, happen, occur) that [as if]…似乎……
(5) If it were not for…/ If it hadn’t been for…若不是因为……
四、it用作形式宾语
当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时，通常会在宾语补足语前使用形式宾语，而将真正的宾语移至句末。其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”。如：
I find it difficult to do the job well.
I think it best that you should stay here.
We think it no use complaining.
五、用于强调句型
即“It is/was＋被强调部分＋that/who/whom+其它”句型之中。

It was in the street that I met your father yesterday.

It的用法及典型句型归纳. 个人总结
It的用法及典型句型归纳 一、人称代词it的最基本用法是作代词，主要指刚提到的事物，想法，以避免重复;也可以指性别不明或性别被认为是不重要的人或动物；未指明但谈话双方都明白的事情或情况。 ①They watched the train until it disappeared in the distance. ②Is this your dog？No, it isn’t. ③I hate it when people talk with a full mouth.． 二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等： It is a lovely day, isn’t it? // It was nearly midnight when she came back. It is April First today. // It is some 3000 kilometers from A to B. It is three dollars. // Today it is 30 degrees centigrade. 三、作形式主语，替代主语从句，动词不定式，或动名词短语 1.作形式主语替代主语从句 ⑴It is clear ( obvious，true，possible，certain....) that ＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂ ⑵It is important ( necessary，right，strange，natural...) that + (should ) do (虚拟语气) ┅是重要的(必要的,对的,奇怪的,自然的┅) ⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that = sb / sth is said (reported/ believed /thought…) to do( to be doing/ to have done) sth ＂据说（据报道，据悉．．．）＂。 ⑷It is suggested ( advised/ ordered / demanded/ insisted/ commanded... ) that +(should ) do ＂据建议；有命令．． ⑸It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that 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。 小练一下： It is very clear that he’s round and tall like a tree. = It is important that we (learn) English well. It is necessary that he (remember) these words. It is said that he has come to Beijing. = It is reported that another earth satellite has been put into orbit. = It is suggested that the meeting ( put off). It was ordered that we (arrive) there in two hours. It is a pity that such a thing ( happen) in your class. It is a pity that he (be) ill. 2.作形式主语替代不定式 . ⑴It is kind ( of sb. ) to do sth.= sb be kind to do sth.一般都是表示人的特性的形容词。如： bad /brave /careless/ clever /cruel / foolish / good （好心的）/ honest/ kind / lazy / modest/ naughty/ nice（有教养的）/polite/ rude / silly / stupid / wise ，等。 Eg. It is kind of you to give me a hand. = ⑵It is necessary ( for sb. ) to do sth. .不定式的逻辑主语是由for引起。常见的形容词有： Important/ necessary/ natural/ easy / safe / common / normal / hard / difficult / dangerous/ unusual/ rare / impossible / pleasant Eg. It is important for her to come to the party.
