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”引导主语从句和“it”做形式主语还有强调句型的区别：it引导的主语从句，形式主语就是it，真正的主语在句子的后面，通常是to do的不定式短语。

而强调句的结构
it is/was+被强调部分+that/who+句子其余部分，结构词it is/was和that/ who都是没有实际意思的，只是构成句子结构的词而已。

这个强调句只能强调名词和代词，也就是主语和宾语，不能强调其他句子成分。

主语从句：It is kind of you to help me with my housework.
强调句：It is you who help me with my housework.
主语从句中it做形式主语的常见句型：It+be+形容词+主语从句，如：It is u ncertain whether he can come to Jenny’s birthday party or not. It + be + 名词词组+ 主语从句，这类名词有：a fact, a pity, a shame, an honour，a question等，如：
It’s a pity that you missed the exciting football match.
It remains a question whether he will come or not.
It + be + 过去分词+ 主语从句，这类过去分词有：announced, believed, expected, hoped, decided, reported, said, shown等，如：It is reporte that 16 people were killed in the earthquake.。

一．it引导的强调结构“It is + 被强调部分+ that/who + 句子其他部分”是强调句型。

除了谓语动词不能强调外，句子中其它成分，如主语、状语、宾语或宾语补足语都可以用该句型中加以强调。

A.用强调结构强调句子成分1．强调主语被强调的主语是人时，可用It is/was ... that/who ...，但如果被强调的部分既包括人又包括物，只能用that。

He bought a camera yesterday.-- It was he that/who bought a camera yesterday. 是他昨天买了一架照相机。

The famous writer and his works have aroused great interest among the students.-- It is the famous writer and his works that have aroused great interest among the students.在学生中引起极大的兴趣的正是这位著名作家以及他的作品。

注意：强调“I”时谓语动词的变化形式。

It is I who am to blame. It is me who is to blame. 是我该受到责怪。

（非正式文体）2. 强调宾语She helped me yesterday. --It was me that/whom she helped yesterday. 昨天她帮助的人是我。

They often talk about the school and the teachers. --It is the school and the teachers that they often talk about. 他们经常谈论的是学校和老师。

3. 强调宾语补足语We elected him chairman of the meeting.-- It was chairman of the meeting that we elected him. 我们选他是做会议的主席。

it的用法专项讲解概念引入先看这些句子：1. There is no doubt that the earth is becoming warmer and that it is human activity that has caused this global warming rather than a random but natural phenomenon.2. It was a scientist called Charles Keeling, who made accurate measurement of the amount of carbon dioxide in the atmosphere from 1956 to 1997.3. They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide.4. It was during the 20th century that the temperature of the earth went up about one degree Fahrenheit.这些句子都是强调句，中的斜体词部分标识出了句中的强调句结构。

用法讲解it引出的强调句1强调句的结构：It is / was + 被强调部分（主语，宾语，状语）+ that (who / whom) + 其它部分在强调句型中：1. 被强调部分可以是主语、宾语或状语。

2. 引导词一般用that，如果是人的话，强调主语还可以用who，强调宾语用who和whom皆可。

3. 判断一个句子是否是强调句，我们可以把被强调部分放回到句子中，不需要添加任何成分时，句子就是强调句。

需要注意的是，在考试中，有的题会迷惑大家，许多题以It is开头，但是It is开头的句子并不全是强调句。

强调句型It is (was) +被强调部分+ that (who)+ 句子其他部分。

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，表语或状语，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 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 shewas a famous film star.= Not until she took off her dark glasses did I realize she was= I didn’t realize she was a famous film star until she took off3. 强调句型的句式变换1）强调句型的一般疑问句形式句式特征：Is/ Was it +被强调部分+ that…2）结合特殊疑问词构成特殊疑问句形式句式特征：特殊疑问词+is/was it that…？•例句：•How is it that she turned down our help? 什么原因使得…？•Where was it that you met Tom yesterday? 究竟在哪…？•When was it that you met him in the park? 究竟何时…？•When and where was it that you got to know Mary? 究竟在何时何地…？•Who was it that that came up with the bright idea? 究竟是谁…？•Which book is it that you want to buy? 究竟是哪一本书…？•Whose umbrella was it that you took away? 到底是谁的伞…？3）在强调句型中考察主谓一致与比较结构。

it引导的强调句
it引导的强调句，也称为强调句型，是由一个it + be动词（表示各种时态）+ 被强调部分（通常是名词或代词）+ 其他构成的句子。

它是一种用于凸显重点，使传达的信息更加清晰有力的句型。

it引导的强调句体现在以下三个方面：
1、it 在句子中扮演“形式主语”的角色。

与其他句式不同，这种句式中的it不指代具体的概念，而是作为句子的形式主语，本身没有实际意义，只是为了使整个句子结构更紧凑，从而使得被强调的部分更加突出。

2、it 引导的强调句是一种特殊的结构，它将被强调的部分置于句首，使得被强调的内容更加突出。

而且，它也能够有效地避免主谓重复，使句子更加简洁，突出重点。

3、it 引导的强调句的被强调部分可以是名词、代词、形容词、副词等，因此它能够用于不同的语法结构。

实例：
It was I who talked to him yesterday.
It is not the way, but the will that matters.
It was not until this morning that I realized my mistake.
It is not money but time that he lacks.
It was in this city that I spent my childhood.
总之，it引导的强调句是一种简洁而有力的句型，它能够凸显重点，使传达的信息更加清晰有力。
