It在强调句中的用法考点透视高中高三英语教研组It一词是高中英语中考查比较频繁的一个词，it含义简单却用法众多，透过近几年的高考试题我们可以看出，各省份高考试题对it的考查十分频繁，尤其是关于it在强调句中的用法的考查更是成为了考查的热点。
以下本文结合近几年高考试题对it在强调句中用法的考查，来对it在强调句中的用法进行一个详细的解析和回顾，通过对照高考真题，归纳讲解it在强调句中的用法，以方便同学们进一步系统牢固地掌握有关it在强调句中的种种用法：1．强调句型的基本结构是：“It is (was) +被强调部分+ that (who) + 其它”被强调部分如果是指人则引导词可以用who，其余情况都用that。
强调句也可以有变体形式，例如：It may have been at the Christmas that John gave Mary a handbag.It might have been John who gave Mary a handbag.强调句的判定方法是：将强调句中的it is/was以及连接词that或who去掉，如果句子仍然成立，成分仍然完整，则说明该句是强调句。
强调句理论上可以强调除谓语以外的任何成分，但是在正式英语中，强调句也一般不强调表语（或叫做主语补足语），例如：It is I who am to blame. （强调主语）It was a new pen that Mother gave me.（强调宾语）It was in the classroom that I left my umbrella.（强调地点状语）It is at eleven that the train leaves.（强调时间状语）It was just as he ordered that I acted.（强调方式状语）It was because he was in trouble that I tried my best to help him.（强调原因状语）It was chairman that they elected him.（强调宾语补足语）相关高考试题：（1）It was after he got what he had desired _______ he realized it was not so important.（06年高考辽宁卷第35题）A. thatB. whenC. sinceD. as（2）David said that it was because of his strong interest in literature _______ he chose the course.（06年高考上海春季招生卷第35题）A. thatB. whatC. whyD. how（3）It is what you do rather than what you say _______ matters.（05年高考天津卷第9题）A. thatB. whatC. whichD. this（4）It was only with the help of the local guide ________.（05年高考上海春季招生卷第37题）A. was the mountain climber rescuedB. that the mountain climber was rescuedC. when the mountain climber was rescuedD. then the mountain climber was rescued 答案：（1）A（2）A（3）A（4）B2．强调句的疑问句形式：强调句的一般疑问句：Is/Was it + 被强调部分 + that /who强调句型的特殊疑问句：疑问词 + is/was it + that/who（1）I just wonder ____ that makes him so excited.（06年高考山东卷第32题）A. why it doesB. what he doesC. how it isD. what it is（2）—____ that he managed to get the information?—Oh, a friend of his helped him.（05年高考山东卷第31题）A. Where was itB. What was itC. How was itD. Why was it答案：（1）D（2）C3．It is/was not until…that…表示“直到……时候才”，也是一个强调句型。
高考英语It的用法It是高考英语中一个极其重要的词，其用法多样，在不同的语境中具有不同的意义。
下面我们将从it的用法、句型和固定搭配三个方面进行讲解。
一、it用作实词1、表示时间、天气、距离、温度等自然现象。
例如：It is Monday today.今天是星期一。
It is raining outside.外面正在下雨。
It is 5 kilometers away from here.距离这儿有5公里远。
2、表示观点、看法、态度等主观想法。
例如：I think it is a good idea.我认为这是一个好主意。
We think it is important to learn English well.我们认为学好英语很重要。
二、it用作形式主语当不定式、动名词或从句作主语时，为了保持句子结构平衡，避免头重脚轻，常用it作形式主语，代替不定式、动名词或从句，而把真正的主语放在句尾。
例如：It is important to learn English well.学好英语很重要。
It took me an hour to finish the homework.我花了一个小时完成作业。
三、it用作形式宾语当不定式、动名词或从句作宾语时，为了保持句子结构平衡，避免头重脚轻，常用it作形式宾语，代替不定式、动名词或从句，而把真正的宾语放在句尾。
例如：I think it is important to learn English well.我认为学好英语很重要。
He found it hard to learn English well.他发现学好英语很难。
四、it用于强调句型中强调句型是英语中一个重要的句型，用于突出强调某个成分，特别是主语、宾语和状语等。
在强调句型中，it没有实际意义，只是起到引导作用。
例如：It is I who am the best student in my class.我是班里最好的学生。
⾼中英语语法知识复习-It的⽤法讲解及练习60多题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． 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． 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．(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。
专题03 代词易错题【01】形容词性物主代词的使用易错题【02】不定代词的误用易错题【03】代词it的误用01(2020年新课标全国卷Ⅰ，语法填空，1.5分)Data about the moon’s composition, such as how much ice and other treasures it contains, could help China decide whether ________ (it) plans for a future lunar base are practical.【错因】本题容易出错的主要原因是代词用法掌握不牢。
【问诊】名词前用物主代词.【答案】its【叮嘱】语法填空的纯空格题，可能考察人称代词主格，不定代词，做形式主语或形式宾语it；当句子缺主语获宾语是，填代词。
因为在剧中充当主语或宾语的应是名词或代词，而在语法填空的纯空格中是不要求考生填名词的，所以只要句子缺少主语或宾语，就该填代词。
在给提示词题中，通常是给出人称代词主格，要求考生填其宾语，物主代词或反身代词。
最后熟记一些固定搭配也是有作用的。
例如，some...others, those who..., by oneself 等。
1.(2021.6全国乙卷语法填空)Ecotourism has3(it) origin with the environmental movement of the 1970s.【答案】its【解析】考查形容词性物主代词。
空格所填词与空后的origin一起作has的宾语；同时与空后的origin构成限定关系，因此应填形容词物主代词。
句意：生态旅游业起源于20世纪70年代的环保运动。
故填its。
2.(2019·浙江卷)Everybody wears___57___ same style of clothes.【答案】the【解析】句意：每个人都穿相同风格的衣服。
专题06 It易错点解题方法It在英语中用法很广。
It 可以用作人称代词，也可以用作非人称代词，可作主语也可作宾语。
表示时间，地点，日期，天气，距离，温度等。
It的主要用法有3：1)代词; 2)形式主语；形式宾语。
3)强调句It.看下列句子中的It的用法，你能辨别吗？1.It is Friday today.2. It was very cold last Monday.3. It is about 8:30 now.4. It is 25km from my home to our school.5. It lies in the south of Xi'an city.6. It is 40°C ! You got a high fever!7. It is 5 yuan.Question: What does “it” in these sentences refer to?It refers to the following: 1 date；2 weather；3 time；4 distance；5 place；6 temperature；7 price看懂啦吗？It 可以用作非人称代词，作主语。
表示1 date；2 weather；3 time；4 distance；5 place；6 temperature；7 price 等。
Read and analyze the following sentences.What does “it” in these sentences refer to?1.It is obvious that the water was to blame.2.It is true that he will treat me for breakfast tomorrow.[答案]:it是形式主语。
[解析]：it是形式主语, 句子真正的主语是that引导的主语从句.牢记以下常用于该句型的形容词:It is clear /obvious /true /possible /certain /amazing /ridiculous /necessary /important /strange /natural /impossible /urgent 等+ that从句.思考：为什么要用it做形式主语而把真正主语放到后面去？遵循英语语言的平衡原则，避免句子头重脚轻。
it作形式主语和形式宾语用法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。
e.g. 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（必背）：①It + be + 形容词+（for sb）+ to do sth. / doing / that …. e.g. 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。
)比较：①It + be + 形容词+of sb+ to do sth. / doing / that ….It is brave of him to save the girl in danger without hesitation.(他毫不犹豫地去救那个处于危险中的女孩真是太勇敢了.)②It + be +名词词组+ doing / that ….e.g. It is no good telling lies.(撒谎没好处。
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。
高考英语语法易错题：it的用法考点it的用法考点◆典型陷阱题分析◆1. Everyone knows that _______ is dangerous to play with fire, but _______ is difficult is to prevent children from playing with fire.A. it, itB. what, whatC. it, whatD. what, it【陷阱】很容易误选B，认为两空均考查形式主语。
【分析】最佳答案是D，第一空填形式主语，真正的主语是其后的不定式to play with fire。
第二空填what，what is difficult 是主语从句，注意what is difficult 后的谓语动词is。
请做以下类似试题：(1) I know ______ is important to know my own limitations, but _______ is difficult is to help others to know their own limitations.A. it, itB. what, whatC. it, whatD. what, it(2) Yes, ______ is difficult to find a job nowadays, but _____ is more difficult is try to find such a job with a high salary but little things to do.A. it, itB. what, whatC. it, whatD. what, it2. I dislike _______ when others laugh at me in public or think poorly of me behind.A. thatB. thoseC. itD. them【陷阱】几个干扰项均有可能误选。
【分析】最佳答案是C，因为在通常情况下，like 是及物动词，其后应有宾语(句中it 即为其宾语)。
句中的when 从句不是宾语从句，而是时间状语从句，其中的when 的意思是“当……的时候”。
其实，也有的词典将I don’t like it when (if) … 作为一个句型来处理。
能这样用的动词不多，主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示喜好的动词。
She won’t like it if you arrive late. 她不喜欢你迟到。
He hates it when people use his bike. 他讨厌别人用他的自行车。
请做以下类似试题(答案均选it)：(1) I hate _______ if people say such things in public.A. thatB. ThoseC. itD. them(2) I’d prefer _______ if I didn’t have to get up early on Sundays.A. thatB.

I just pretended nobody was at home, so I didn’t ask who _______ was.A. heB. ThatC. sheD. it【陷阱】容易误选A或C。
【分析】最佳答案是D。
it 用以指身份不明的人。
若指身份明确的人，则不宜用it。
比较：(1) Mr Smith is at the door. _______ wants to see you.(2) Someone is at the door. ________ must be Mr Smith.A. HeB. ItC. ThisD. That第(1)题选A，因为来者身份明确；第(2)选B，因为来者身份不明确。
4. “Excus e me, I want to have my watch fixed, but I can’t find a repair shop.” “I know ________ nearby. Come on, I’ll show you.”A. oneB. itC. someD. that【陷阱】容易误选B。
【分析】最佳答案是A。
it 和one 的区别可简单地概括为：it = the + 名词，one = a + 名词。
如：I haven’t got any pens, and I want to borrow one. 我没有钢笔，我想借一支。
(one = a pen)I have two pens, and I can lend one to you. 我有两本支钢笔，我可以借一支。
(one = a pen)I have a pen, and I can lend it to you. 我有一本钢笔，我可以把它借给你。
(it = the pen)在上面一题中，one 相当于one 相当于 a repair shop。
请做下面一题（答案选A）：There is only one English-Chinese dictionary in that book-shop. I wonder if you still want to buy _______.A. itB. oneC. anotherD. any5. Will you see to _______ that my children are taken good care of while I am away?A. itB. MeC. yourselfD. them【陷阱】几个干扰项均有可能误选。
【分析】最佳答案是A。
it 为形式宾语，真正的宾语是空格后that引导的宾语从句。
see to 意为“负责”、“注意”，其中的to 为介词，不宜直接跟that引导的宾语从句，遇此情况可借助代词it。
请做下面两题，答案也是选it：(1) I’ll see to _______ that all these letters will be sent to the post before twelve.A. itB. meC. whichD. them(2) Will you see to _______ that the luggage is brought back as soon as possible?A. meB. yourselfC. itD. them类似以上see to 用法的短语还有depend on, answer for 等。
