it用法+练习题
It的用法总结
在英语中,it有许多不同的用法,它既可以用作代词(如人称代词、非人称代词)，也可以用作引导词（作形式主语或形式宾语），还可以用来构成强调句型。
1.it用作代词
(1) 用作人称代词在句子中作主语或宾语；指前面已经提到过的事物、动物或人，且it指特定的事物；如果指前文中提到的事物中的任何一个，用one。one可以与any, each, every, not等连用，但one不可代替不可数名词。
—Where’s your car?
—It’s in the garage. 你的汽车在哪儿呢？在车库里。(指代物品your car)
Did you hit it? 你打中了吗？(指代事件)
The baby cried when it was hungry.这婴儿饿时就哭。（指代婴儿，尤指性别不详或无所谓时）
—Who is that?
—It’s me. 是谁？我。(指一定情景中所确定的人或事物，此时相当于指示代词，代指this 和that,有时也指人)
—What’s this?
—It’s a box. 这是什么？一只箱子。
(2) 作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。也可模糊地指一般情形或上文的部分或整个意思。译成汉语时，it通常不一定译出来。
It’s a long time since they left. 他们走后很久了。
It’s two miles to the beach.离海滨有两英里远。
That’s just it—I can’t work when you’re making so much noise.原因就在这里——你弄出这么大的声音，我工作不了。
另外，需要注意两点：
（1）“It’s time…”后面可以接不定式和介词短语表示“是做……的时候了”。如：
It’s time for supper. It’s time to have supper.
(2) “It’s time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如：
It’s time we had lunch.是我们吃饭的时候了。
It’s time we started.是我们该出发的时候了。
2.it用作引导词
(1) 作形式主语由动词不定式、动词-ing短语或名词性从句担任主语的句子，常用it 来作形式主语，而把真正的主语放在句子的后面。
It’s not easy for us to learn English well. [句型为: It +be+形容词+（for sb.）to do sth.]
It’s foolish of you to say that to her. [句型为: It +be+形容词+（of sb.）+to do sth.]
It’s no use/good/help…sleeping too much. (句型为: It +be+名词+doing)
It’s important that we be there on time.（句型为: It +be +形容词+that从句）
It’s high time that Tom went to school. (句型为: It +be +time +that从句，从句中的动词用过去时)
It was the second time that he had telephoned me that day. [句型为: It +be+ the first(second, third)time +that从句]（that从句中动词用完成时）
It was arranged that they should leave the following winter. (句型为: It +be+过去分词+that
从句)
It appears that the two leaders are holding secret talks. (句型为: It +不及物动词+that从句)
(2) 作形式宾语当宾语是动词不定式、动词-ing短语或名词性从句时，而宾语后又有宾语补足语，则需用it作形式宾语，将真正的宾语放到宾语补足语的后面。用于这种结构的动词有：feel, find, think, make, consider, take等。
Marx found it important to study the situation in Russia.马克思发现研究俄国的形势很重要。
I find it strange that she doesn’t want to travel.她竟不想旅游,我觉得很奇怪。
I’ ll make it clear to you that failure is the mother of success.我要告诉你们失败是成功之母。
3.it用在强调句型中
英语中，为了突出句子中的某一成分，达到强调或使人特别注意该成分的目的，人们常用“It is/was+强调对象+who/whom/that….”句式把整个句子分割成前后两个部分，使之各自有自己的谓语动词，中间由that或who/whom连起来成为一个新句子。除强调人时用who, whom外，其余情况都用连词that。被强调的对象仅限于句子的主语、宾语、宾语补足语和部分状语（包括状语从句），即除谓语和定语以外的句子成分。这部分状语主要包括地点状语、由before, when, after, not until等引起的时间状语从句、由because, because of引起的原因状语、由by引起的方式状语等。
当被强调的对象是人时，可用who, whom或that，其余情况一律用that; 当被强调对象在从句中做主语时用who/that,当被强调对象在从句中做宾语时用whom/that。
原句：My father did the experiment in the lab yesterday evening.昨天晚上我父亲在实验室做实验。
It was my father did the experiment in the lab yesterday evening.昨天晚上是我父亲在实验室做实验。（强调主语）
It was the experiment that my father did in the lab yesterday evening.昨天晚上我父亲在实验室里做的是实验。（强调宾语）
It was yesterday evening that my father did the experiment in the lab.我父亲是昨天晚上在实验室做实验的。（强调时间状语）
It was in the lab that my father did the experiment yesterday evening.我父亲昨天晚上是在实验室里做这个实验的。（强调地点状语）
另外，再注意两点：
（1）强调句如果还原成陈述句的话，句子成分是完整的，如果不完整，那必然是别的从句而不是强调句。
It was the town where we lived for three years.此句是定语从句，因为还原以后的句子为: We lived the town for three years.缺少介词（in the town）, 而It was in the town that we lived for three years.这就是一个强调句了。
（2）强调中心也可以是疑问词，这时要将疑问词置于句首，构成一个特殊疑问句。
Why is it that you want to leave so soon? 你到底为何这么早就要走？

英语it的用法及练习
it的用法及练习 一、概述 在英语中，it的使用相当广泛，它既可用作代词，如人称代词（personal it）、指示代词（demonstrative it）及非人称代词（impersonal it）, 也可用作引导词（anticipatory it）和强调结构中的强调词（emphatic it） Someone is ringing the doorbell. Go and see who it is.有人在按门铃。去看看是谁。（人称代词）What’s this?这是什么？ It’s a book.这是一本书。（指示代词） What a long way it is from Beijing to London! 从北京到伦敦真远。（非人称代词） It's best to plant trees in spring because it's warmer.春天是植树的最佳时节，因为天气更暖和。（作引导词） It was I who met him in the park last week. 是我上星期在公园遇到他的。（强调结构中的强调词） 二、it作代词 1、用作人称代词（personal it） 代替前文提到过的事物，it作真实主语或宾语。 The frog is not a warm-blooded animal. It is a cold-blooded one.青蛙不是温血动物，它是冷血动物。My pen is missing. I can't find it anywhere. 我的笔丢了，我哪儿也找不到它了。 I won't be back tonight. Please tell my wife about it .我今晚不回来了，请你向我妻子说一声。 I was disappointed with the film. I had expected it to be much better. 我对这部电影很失望，我曾盼望它更好。 Tom's mother kept telling him that he should work harder, but it didn't help.汤姆的妈妈不停地告诉他要努力，但这没起作用。 2、用作指示代词（demonstrative it） 相当于this或that，it有时不特指某件东西，而代表前面已提到的或将会发生的某件事情。 -Who is knocking at the door? —谁在敲门？
2011届高考英语一轮复习讲解：it的用法
2011届高考英语一轮复习讲解：it的用法【知识要点】 It的用法 （一）作人称代词 1、it代替前面（或后面）的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.（it代替前面的cake） Although we cannot see it, there is air all around us. （it代替后面的air） They say he has left town, but I don’t believe it.（it代替前面They…town分句中的情况） 2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree） The baby cried because it was hungry. （it代替前面的baby） 3、在某些习惯说法中，可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构
it的用法归纳
?Never be afraid of grammar ?Collect some examples; ?Watch them very carefully; ?Find out something in common; ?Try to use the rules ---- practise. it用法完全归纳 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. 我把手表掉在地上摔坏了。 It’s hard work, but I enjoy it. 工作很辛苦，可是我乐意干。 “Where is the dog?”“It’s in the bedroom. ”“狗在哪?”“在卧室里”。 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? 是男孩还是女孩? There is a knock on the door. It must be the postman. 有人在敲门，一定是邮递员。 【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. ”“这是什么?”“是一种新机器”。 Nothing is wrong, is it? 没出什么问题，是吗? 二、it 作非人称代词的用法 1.基本用法 it 作非人称代词的用法，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. 现在去那儿已经太迟了。 It rained all day yesterday. 昨天下了一天的雨。 It can get very hot here. 这里有时会很热。 2.用于某些句型 It’s time for sth. 该做某事了。 It’s time to do sth. 该做某事的时候了。 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 first (second) time + that-从句. 某人第几次干某事。(从句谓语用现在完成时)

It的用法 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“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。 1．(NMET98) It was only when I reread his poems recently ___ I began to appreciate their beauty．A．until B．that C．then D．so 正确答案：B 此题考查强调句，所以用that。 2．(NMET98) I hate____when people talk with their mouths full． A．it B．that C．these D．them 正确答案：A 此题考查it作形式宾语的用法，所以选A。 3．(MET91，短文改错)David and I did not agree and David pointed to a path which he thought it would probably lead to a village． 正确答案：去掉it，因为定语从句中已有宾语which。 一、要点点拔 1．代替上文中提到过的人或事物。指代人时，一般用于小孩或身份不十分明朗的人。 1) －Who is the baby? －It‘s my teacher’s son． 2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you． 2．用于表达天气、环境、时间、距离、季节等。例如： 1) It’s half an hour’s walk from here to our school． 2) It‘s nice and warm here． 3) But it's two o'clock now, and it's time for us to go to school． 3．用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。 1).It 替代真正的主语——动词不定式短语.

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.
