1、1考点 33 it 的用法高考频度：考向一 it 作人称代词1.用来指代前文中提到的东西。既可指代具体的东西，也可指代一种情况。请看下面的例子1）I hear you bought a new bike, can you show it to me？ 2）If I can stop her coming to you, I shall do it. 3）I want to stay here for a night.Your wife wont like it此时要注意与其他代词如 that, one, those, this, another 等的区别： 1.I hear you bough

2、t a new bike, I want to buy _ , too.此处应填 one，因为这里我并不是要买你的车，而是一辆新车，one a new bike。 2.I have bought a new bike, but I still want to buy _ .此处应填 another。我已有了一辆，再买另一辆。another another new bike。 3.We see him when we come to town, but _ isnt often.此处填 that 或 it 均可。指代前面我们去城里时可以看到他这一情况。 4.My seat is next to

3、_ of the headmaster.此处应填 that，用来代替名词seat，thatthe seat。 5.The bikes made this year are better than _ made last years.此处应填those 或 the ones。代替前文的 bikes，因其是复数概念，故用 those 或 the ones，those the onesthe bikes。 2.也可以指动物Is this your dog？No, it isnt.3 用来指代人。说明某人的身份或者做某事的人；指代婴儿或儿童；在不清楚某人性别时，也可使用 it，尤其在问答的形式中更为常

4、见。例如： Who is it? Its me. 2Who is it there? Its I (me/you/he).I thought it was Mary, but it was not she.Her face lighted when she saw who it was.1.（2018新课标卷 I语法填空）If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give_70_a try

5、.【答案】it running【解析】考查代词或名词的用法。我们都应该试试跑步。此处 give it a try 意为：试试。此处 it 可以指 running。故填 it 或 running。2.Whos that at the door?_ is the milkman.A. He B. It C. This D. That【答案】B【解析】考查代词的用法。句意：谁在门外？是送牛奶的。因为不知道门外的是什么人。故用 it 指代不清楚的人。故选 B。3.If I can help_, I dont like working late into the night.A. so B. that

6、C. it D. them【答案】C考向二 非人称代词 itit 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，称为非人称的 it：1.指天气：It is a lovely day, isnt it? 3It is a bit windy.2.指时间: It was nearly midnight when she came back. 3.指环境: It was very quiet in the caf. 4.指距离：It is half an hours walk to the city centre. 5 指日期：Whats the date today

7、? Its the eleventh, October.6 指季节：It is summer now.7 指度量：It is about 20 pound/kg8.指价值：- Whats the cost of the dictionary?-It is sixty-three.9 指温度 Its 35 centigrade now. So I feel hot.He got his first book published. It turned out to be a bestseller.When was _?_ was in 2000 when he was still in colle

8、ge. A. that; This B. this; It C. it; This D. that; It【答案】D考向二 作形式主语，替代不定式、ing 形式或主语从句（一） 作形式主语替代主语从句1.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 hes round and tall like a tree. = That hes round and tall

9、like a tree is very clear. It is important ( necessary， right， strange， natural.) that . 该句型和上一个同属一个句型；由于主句中的形容词不同，that 后的从句中要用虚拟语气4（should + 动词原形） ，should 可以省去，建议记住该句型中的形容词。It is important that we (should) learn English well. It is necessary that he (should) remember these words. 2. It is said (rep

10、orted/ learned/believed/thought/known/told/hoped.) 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. It is reported that another earth satellite has been put into orbit. 该句型常可以转换成含有宾语从句的复合句或者含有不定式作主补的简单句。例如： Its said that Tom has come back from abroa

11、d.People say that Tom has come back from abroad.He is said to have come back from abroad. It is suggested ( ordered /demanded/insisted/commanded. ) that . 该句型和上一个同属一个句型，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 o

12、ff. It was ordered that we ( should ) arrive there in two hours. 3.It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/. ) 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. 这种事竟然发生在你们班上，真

13、是遗憾！ It is a pity that he is ill. 他生病了，真遗憾！ 4. It happens (seems， looks， appears ) that. 该句型中 it 是形式主语，that 引导的是主语从句，主句中的 happen ， seem 等词是不及物动词。It happened ( so happened ) that he met his teacher in the street. 碰巧It seems that he enjoys pop songs very much.看来他非常喜欢流行歌曲。该句型可转换成含不定式的简单句。如上述两句可分别转换为：He

14、 happened to meet his teacher in the street.He seems to enjoy pop songs very much.55.it 代替连接代词或连接副词引导的从句作形式主语 （1）It is known（not decided，not made clear，found out，discussed，being discussed，being considered，a question，uncertain 等）连接代词或连接副词引导的从句。 It is still a question when we shall have our sports mee

15、t. 我们将什么时候举行运动会还是一个问题。 It is uncertain whether he can attend this conference or not. 他能否来开会还不能确定。 （2）It doesnt matter（ Its no wonder；It doesnt make too much difference等）连接代词或连接副词引导的从句。 It doesnt matter whether we go together or separately.我们一起去还是分开去都可以。 It is no wonder why he came here too late.他为什么

16、来这么晚不足为怪(二)作形式主语替代不定式。常见的句型有： 1. . 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）

17、等。 这个句型可以改写为：sb. is kind to do sth. 。 It is kind of you to say so. = You are kind to say so. It is necessary ( for sb. ) to do sth. 该句型与上一个同属一个句型，如果不定式的逻辑主语是由 for 引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。 常见的形容词有： important， necessary， natural easy， safe， common， normal， hard， difficult， dangerous，

18、unusual， rare， impossible， pleasant 等。 =在中的形容词作表语可以用从句改写， 如： It is important for her to come to the party. = It is important that she (should ) come to the party. 2.It takes 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。 6It took thousands of people many years to build the Great Wa

19、ll. (三) 作形式主语替代 ing 形式It is no good / no use/useless doing sth. 该句型中的真正主语是动名词短语。It is no good learning English without speaking English. Its useless trying to argue with Shylock.考向四 作形式宾语，代替不定式、ing 形式、宾语从句。1. We think it important to learn a foreign language. 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

20、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 等引导的宾语从句。 We think it our duty to clean our classroom every day. They found it difficult that they would finish their work in two days.The professor thinks it no good reading with

21、out understanding.The Internet makes it easier for companies to keep in touch with customers.Susan made_ clear to me that she wished to make a new life for herself. A. that B. this C. it D. her【答案】C【解析】这是一个宾语从句，make 的宾语是 that 引导的句子，在本句中用 it 做形式宾语代指 that 引导的宾语从句。句意为：Susan 向我表明她希望能过上新的生活。故答案选C。2. As t

22、he busiest woman in Norton, she made_ her duty to look after all the other peoples affairs in that town.A. this B. that C.one D.it【答案】D72. 在 like, dislike, hate, love, take, appreciate, depend on, see to(处理)，insist on，help 等动词后，形式宾语 it 后可直接跟宾语从句。此时，it 表模糊概念，指代后面所叙述的内容。You may depend on it that I sha

23、ll always support you.I hate it when people laugh at the disabled.I will appreciate it if you can help me with my English.How would you like if you were watching your favorite TV program and someone came into the room and just shut it off without asking you?A. them B. one C. those D. it【答案】D【解析】句意：当

24、你正在看一个你喜欢的节目时，突然有个人进来，一声不吭地关掉电视，你会怎么想？It 作形式宾语，指代 If 后面的句子。该句涉及到了一个疑问句，一个条件状语从句（if）和两个并列句(and)。这当时应该先把它转化为陈述句 you would like_分析句子结构知道 like 之后缺少一个宾语，需要一个宾格代词充当，所以答案选 it。考向五 it 的重要句型 1.强调句 It is/was + 被强调部分 + that/who . 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，表语或状语，强调的主语如果是人，that 可以由 who 换用。

25、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 about 600 years ago that the first clock with a face and an hour hand was made. It was they that (who ) cleaned the classroom yesterday. It was in the street 8that I met her father. It was yesterday that I met her in the street.It is you that /who a

26、re wrong.I think it was Jack said this.(其中省略了 who 或 that)What is it you want me to do?(it 后省略了 that) It is 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

27、 off her dark glasses did I realize she was a famous film star. = I didnt realize she was a famous film star until she took off her dark glasses. 强调句型的两种变形形式：一般疑问句形式：Is/ Was it that? 特殊疑问句形式：Who/ Whom /When/ When 等 + is/ was it that ?1)Was it in 1979 _ the American astronaut succeeded _ landing on t

28、he moon? A. when; on B. that; on C. when; in D. that; in (Key: D)2）Was _ that I saw last night at the concert?

29、iticizing me, but is how she does it that I object to.A. it B. that C. this D. which【答案】A92.It be 的适当形式时间 when-clause 这个句型中，it 指时间，而且表示时间的词语前没有介词（时间一般为具体时间） 。主句中的谓语动词和从句中的谓语动词在时态上一般是一致的，主句是 will be，when 从句用一般现在时代替一般将来时。常译为当的时候，是例如： It was already 8oclock when we got home. It will be midnight when th

30、ey get there.It was five oclock in the afternoon _ they climbed up to the top of the mountain.It was at five oclock in the afternoon _ they climbed up to the top of the mountain.A. since B. when C. that D. until 3.It is/has been一段时间 since-clause 这个句型表示从 since 从句谓语动作发生以后到现在或过去所经过的一段时间，意为自从以来已多久了since

31、 从句后用一般过去时，例如： It ishas been three years since his father passed away.他父亲去逝已经有三年了。It is/has been fifteen years since she left Shanghai.她离开上海已经 15 年了4. It is time ( about time ，high time ) that . 该句型中 that 后的从句应该用虚拟语气，常用一般过去时态表示虚拟.It is time that children went to bed. It is time you bought a new car.

32、It is (high ) time you made up your mind.It is the first ( second . ) time that . 该句型要和上一个句型区别开来，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 替换.常译为是第一（二）次。 It is the first time I have been here. = This is the first time I

33、 have been here.It was the fifth time（that）I had paid a friendly visit to Africa.105.It be 的适当形式一段时间before-clause 这个句型中的时间一般为表示一段时间的词语（如：long，years，months，weeks，days ， hours，minutes） ，主句中的谓语动词用肯定式，意为过多长时间才。主句的谓语动词是否定式时，意为没过多长时间就。主句的时态可用过去时 was 或将来时 will be；用 was 时，before 从句的动词用一般过去时；用 will be 时，befo

34、re 从句常用一般现在时。例如： It was not long before she learned those poems by heart .她没过多久就背会了那些诗歌。 It was long before the police arrived.过了很久警察才来。It will be hours before he makes a decision.要过好几个小时他才会作出决定。It will not be hours before we meet again.要不了几个小时我们还会再见面的。 6. It looks ( seems ) as if . 该句型中 it 无意义， as

35、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.（真的病了） It looks as if he were ill. （没有生病） It seemed as if he were dying. 题组一 能力过关I单项填空1.Young people should be independent, and dont take _for granted that you can depend on your parents when in trouble.A.one B.it C. this D. that2.He did
