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。
it作形式宾语和引导强调句的用法小结
1. IT作形式宾语的用法：
- 当主语是不定式或从句时，可以用it作为形式宾语。
例：I find it difficult to understand this book.（我发现理解这本书很困难。
）
- 当主语是动词的-ing形式时，可以用it作为形式宾语。
例：I enjoy it when you sing.（当你唱歌时，我很享受。
）
2. 引导强调句的用法：
- 强调句一般由以下结构构成：It is + 被强调部分 + that/who + 其他部分。
- 当被强调部分是名词时，用that来引导强调句。
例：It was John who won the competition.（赢得比赛的是约翰。
）
- 当被强调部分是代词时，用who来引导强调句。
例：It was he who broke the vase.（打破花瓶的是他。
）
- 当被强调部分是形容词或副词时，用that来引导强调句。
例：It is very important that you study hard.（你努力学习非常重要。
）
需要注意的是，强调句的语序需要颠倒，被强调部分放在句首。
此外，引导强调句的it没有实际意义，只起连接作用。
英语强调句及it用法大全强调句、It的用法、省略和插入语一、强调句（一）强调句句型1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who （当强调主语且主语指人）+ 其它部分。
e.g. It was yesterday that he met Li Ping.2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？e.g. When and where was it that you were born?4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.强调宾语：It was Li Ming that I met at the railway station yesterday.强调地点状语：It was at the railway station that I met Li Ming yesterday.强调时间状语：It was yesterday that I met Li Ming at the railway station.5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。
独立主格结构独立主格结构由两部分组成，前一部分是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。
前后两部分具有逻辑主谓关系。
独立主格结构在句中做状语，多用于书面语。
独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。
非谓语动词作状语，其逻辑主语必须与主句主语保持一致。
若不一致，非谓语动词形式必须另带主语，从而构成复合结构的形式作状语，这种结构称为“独立结构”。
其中，非谓语动词主动用现在分词，被动用过去分词。
非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。
“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。
功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。
例如：表示时间The meeting being over, all of us went home. 开完会后我们都回家了。
Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝杯茶。
表示条件The condition being favorable, he may succeed. 若条件有利，他或许能成功。
表示原因There being no taxis, we had to walk. 没有出租车，我们只好步行。
He wrapped her up with great care, the night being dark and frosty.夜又黑又冷，所以他把她裹得严严实实的。
表示伴随情况Almost all metals are good conductors, silver being the best of all.=Almost all metals are good conductors, and silver is the best of all.几乎所有的金属都是良导体，而银则是最好的导体。

原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。
了解中的强调句与插入语的用法在语言表达中，为了更加准确地传达信息或者加强表达的效果，我们经常会使用强调句和插入语。
强调句是指通过语法结构和语气的变化来强调一些信息，而插入语则是在句子中插入一些额外的语言成分，用于注释、补充或者强调某个概念。
本文将详细介绍中文中的强调句和插入语的用法。
一、强调句的用法强调句是为了凸显某个信息而特别设计的句子，通过特殊的语法结构和重复的表达方式来达到强调的效果。
下面是几种常见的强调句的用法：1. 句型“是……才”这种句型常用来表达对比或者强调某种特定情况。
例如：“是你才能做到这样的成绩。
”这种句型中，“是”起到了强调的作用，突出了“你”这个人。
2. 句型“不是……而是”这种句型常用于强调两个相对的事物或者概念。
例如：“他不是聪明，而是勤奋。
”这种句型中，“不是”和“而是”起到了将注意力集中在“勤奋”这个方面的作用。
3. 句型“不是……就是”这种句型用于强调两种可能性，常用于列举选项或者对比不同情况。
例如：“他不是在家里，就是在办公室。
”这种句型中，“不是”和“就是”强调了两种情况的对立性。
二、插入语的用法插入语是插入到句子中的一部分，用于注释、补充或者强调某个概念。
插入语的存在不影响句子的整体结构，但可以使句子更加准确或者生动。
下面是几种常见的插入语的用法：1. 插入语的位置插入语通常放置在句子中间，可以插入到主语、谓语、宾语等各个部分之间。
例如：“我昨天，也就是星期三，去了一趟图书馆。
”这里，“也就是星期三”是插入语，用于解释“昨天”。
2. 插入语的结构插入语可以是一个词、一个短语或者一个从句。
例如：“我的哥哥，也就是上海交通大学的教授，已经发表了多篇学术论文。
”这里，“也就是上海交通大学的教授”是一个插入语，用于补充说明“我的哥哥”的身份。
3. 插入语的标点符号插入语通常用逗号或者破折号来与其他部分分开。
例如：“她终于找到了那本书，你知道的，那本全世界都在疯狂追捧的畅销小说。
强调句、It的用法、省略和插入语语法复习五：强调句、It的用法、省略和插入语一、强调句（一）强调句句型1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分。
e.g. It was yesterday that he met Li Ping.2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？e.g. When and where was it that you were born?4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.强调宾语：It was Li Ming that I met at the railway station yesterday.强调地点状语：It was at the railway station that I met Li Ming yesterday.强调时间状语：It was yesterday that I met Li Ming at the railway station.5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。
语法复习五：强调句、It的用法、省略和插入语一、强调句（一）强调句句型1、陈述句的强调句型：it is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分。
e.g. it was yesterday that he met li ping.2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. was it yesterday that he met li ping?3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？e.g. when and where was it that you were born?4、强调句例句：针对i met li ming at the railway station yesterday.句子进行强调。
强调主语：it was i that (who) met li ming at the railway station yesterday.强调宾语：it was li ming that i met at the railway station yesterday.强调地点状语：it was at the railway station that i met li ming yesterday.强调时间状语：it was yesterday that i met li ming at the railway station.5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who 不可省略；强调句中的时态只用两种，一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用it was …，其余的时态用it is …。
（二）not …until …句型的强调句1、句型为：it is/ was not until + 被强调部分+ that + 其它部分e.g. 普通句：he didn’t go to bed until/ till his wife came back.强调句：it was not until his wife came back that he went to bed.2、注意：此句型只用until，不用till。
但如果不是强调句型，till, until 可通用；因为句型中it is/ was not …已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。
（三）谓语动词的强调1、it is/ was …that …结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或did。
e.g. do sit down. 务必请坐。
he did write to you last week. 上周他确实给你写了信。
do be careful when you cross the street. 过马路时，务必（千万）要小心啊！2、注意：此种强调只用do/ does和did ，没有别的形式；过去时用did ，后面的谓语动词用原形。
二、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）共8页，当前第1页123456783、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 factory.it is eighteen square metres in area.what does it matter?（三）作强调词，构成强调结构用以帮助改变句子结构，使句子的某一成分受到强调。
“it is (was) + 所强调的成分+ that (who) + 其它成分。
”在这个句型中，it本身没有词义。
详见“一、强调句”。
（四）引导词it作形式主语（宾语）为了使句子平衡，常采用形式主语（或宾语）it ，而把真正的主语（或宾语）置于句子后面。
通常引导词it与它所代替的句子成分中间要夹有某些词。
e.g. it takes half an hour to go there on foot.（it与to go there on foot之间夹有takes half an hour四个词）we thought it strange that mr smith did not come last night. （it与that 从句中间夹有strange）但有时it与所替代部分之间并不夹有其它词。
e.g. you may depend on it that they will support you.（因为介词on之后一般不直接接that引导的宾语从句。
注意：it不是多余的，不能当作错句）练习一、强调句、it的用法1. my bike is missing. i can’t find ____ anywhere.a. oneb. onesc. itd. that2. ---- who’s that?---- ____ professor li.a. that’sb. it’sc. he’sd. this’s3. ____ was jane that i saw in the library this morning.a. itb. hec. shed. that4. ---- have you ever seen a whale alive?---- yes, i’ve seen ____.共8页，当前第2页12345678a. thatb. itc. suchd. one5. the color of my coat is different from ____ of yours.a. thisb. thatc. itd. one6. ____ will do you good to do some exercise every morning.a. itb. therec. thosed. you7. we think ____ our duty to pay taxes to our government.a. thatb. thisc. itsd. it8. the climate of shanghai is better than ____ of nanjing.a. thatb. itc. whichd. what9. ____ four years since i joined the army.a. there wasb. there isc. it wasd. it is10. how long ____ to finish the work?a. you’ll takeb. you’ll take itc. will it take youd. will take you11. it was through xiao li ____ i got to know xiao wang.a. whob. whomc. howd. that12. it was in the rice fields ____ we had our league meeting.a. whereb. thatc. in whichd. on which13. it was on october 1st ____ new china was founded.a. whichb. whenc. asd. that14. was it because he was ill ____ he asked for leave?a. andb. thatc. that’sd. so15. mary speaks in a low voice; ____ is difficult to know what she is saying.a. itb. thatc. sod. she16. it was ____ i met mr green in shanghai.a. many years thatb. many years beforec. many years ago thatd. manyyears when17. ____ is not everybody ____ can draw so well.a. it, allb. it, thatc. there, whod. there, that18. so ____ that no fish can live in it.a. shallow is the lakeb. the lake is shallowc. shallow the lake isd. is the lake shallow三、省略为了使讲话和行文简洁，句中某些成分有时可省略。
