“It is (was) … that(who)…”结构的强调句
小议强调句型“it is-was+被强调部分+that-who”
小议强调句型“it is/was+被强调部分+that/who”“强调”就是使句子的某一部分比一般情况下显得更加重要。
英语表达中，要强调句子的某一成分，一般可用强调句型“it is （was）+that （who） +句子的其余部分”。
it在句中无意义，只起引出被强调部分的作用。
被强调的部分指人时，除可用that外，还可换用who（强调宾语指人时也可用whom）。
使用强调句型时，应注意以下事项。
一、如何判断强调结构去掉强调结构it is （was）… that（who）…后，剩余成分略作调整或不作调整仍然能组成一个语法结构完整的句子，即为强调句。
这是判断是不是强调句型的关键。
试比较：a： it is surprising that tom arrives at school so early. b： it is tom that arrives at school so early.将a句中的it is… that去掉后，句子结构不完整，我们可以判断它不属于强调句型，属于主语从句。
将b句中的it is… that 去掉后变为：tom arrives at school so early.这是一个完整的句子，故我们判断b句属于强调句。
二、强调结构可以强调哪些句子成分一般而言，强调结构几乎可以强调除谓语动词及形容词作表语之外的任何句子成分，如：mary got the dictionary in this bookstore with the help of her friend yesterday.it was mary that got the dictionary in this bookstore withthe help of her friend yesterday.（强调主语）it was the dictionary that mary got in this bookstore with the help of her friend yesterday. （强调宾语）it was in this bookstore that mary got the dictionary with the help of her friend yesterday.（强调地点状语）it was with the help of her friend that mary got the dictionary in this bookstore yesterday. （强调方式状语）此外，该强调句型中，被强调的成分除了是名词、代词、介词短语等之外，也可以是从句。
强调句型要点归纳
强调句型要点归纳强调句型的结构是“It is(was)+被强调部分+that(who)+其它”。
学习强调句型要注意以下七点：1.被强调部分可以是句子的主语、宾语、宾语补足语、状语，但不能强调句子的谓语；被强调的部分指人时用who 或that，强调状语时只能用that。
It is he who/that painted the door yellow. 是他把门漆成了黄色。
（强调主语，指人）It is this novel that they talked about last night. 他们昨天晚上讨论的就是这本小说。
（强调宾语）It was at an evening party that I first saw her. 我是在一次晚会上第一次见到她的。
（强调状语）2. 强调主语时，that/who后的动词要和主语在人称和数上保持一致。
如：It is I who am responsible for it. 是我应该对此负责。
It is he that is to blame. 该受谴责的是他。
3. 使用强调句型时要注意代词的格。
如果强调的是主语，应该使用主格；如果强调宾语，应使用宾格。
如：It was they who were late for the meeting. 是他们开会迟到了。
4. 强调句型的疑问句结构是：（1）一般疑问句：Is/Was it +被强调部分+that(who)+其它；Was it in 1996 that he joined the army? 他是1996年参军的吗？Was it Doctor James that we invited to give us a lecture? 被邀请给我们作报告的是詹姆斯博士吗？（2）特殊疑问句：特殊疑问词（what, who, when, how, why）+is/was +it +that(who)+其它。
如：What is it that makes him so angry. 到底是什么使他如此生气？Who was it that she gave the money to? 他到底给了谁？When was it that you first met him? 你是在什么时候第一次见到他的？5. not…until …句式的强调句形式是：It wasn’t until…that…。

初中英语知识点归纳强调句的构成与用法强调句是英语中常用的一种句型，用于表示强调或突出某一信息或观点。
在初中英语中，掌握强调句的构成和用法对于提高语言表达能力至关重要。
本文将对初中英语中的强调句进行归纳，以帮助学习者更好地理解和运用。
一、强调句的构成强调句通常由以下三个部分构成：1. It is/was + 被强调部分 + that/who/whom例如：- It is John who won the first prize in the singing contest.约翰赢得了唱歌比赛的第一名。
- It was yesterday that I received the news of his arrival.就在昨天，我收到了他到达的消息。
2. What/How + 被强调部分例如：- What a beautiful flower!（多么美丽的花啊！）- How hard he works!（他工作得多么努力！）3. 倒装结构在强调句中，除了使用"It is/was"和"What/How"结构外，还可以采用倒装结构来实现强调的效果。

例如：- Not only did she finish her homework, but also she helped her classmates.（她不仅完成了作业，还帮助了同学们。
）二、强调句的用法强调句常用于以下几种情况：1. 强调句中的被强调部分是最重要的信息，希望突出强调。

强调结构“it is +...+that从句”应注意的几个问题
强调结构“It is+…+that从句”应注意的几个问题“It is/was + 被强调部分+that /who +其他”这一结构是最典型的强调结构，也是历年高考的重点。
它的特点是去掉it was ….that这一框架后，所剩部分仍为一个完整的句子。
如：It was how the young man had learned five foreign languages that attracted the audience's interest. 吸引听众兴趣的是那个年轻人如何学会了五种语言。
使用这一结构要注意以下几点：一、主谓一致1、that \ who后面的谓语要与主句一致。
如：It is Lucy who (that) often helps me with my English. 是Lucy经常帮助我学习英语。
（主语是Lucy）It is Lucy and Lily that (who) often help me with my English. 是Lucy和Lily经常帮助我学习英语。
（主语是Lucy和Lily）尤其需要注意的是，在强调either …or…, neither …nor …, not only…but also…等词组所构成的句子时，that或who后的谓语动词要根据就近原则，如：It was neither you nor he that is willing to the Great Wall. 既不是你也不是他愿意去长城。
在强调有as well as, not…but, together with, except, like等短语构成的句子时，谓语动词要与这些词前面名词数一致，如：It was he as well as his classmates that has ever been to Suzhou. 是他，还有他的同学，曾经去过苏州。
It was Mr. Green, together with his wife and children is in China now. 是格林先生和他的妻儿已来到了中国。
高中英语语法：特殊句式 之强调句
高中英语语法：特殊句式之强调句一、It is ...that/who 强调句1、基本结构：“It is/was +被强调部分+that/who+其他成分”强调句结构可用来强调句子的主语、宾语和状语等。
◇It was a European chemistwho produced the medicine.(强调主语)是一位欧洲药剂师发明了这种药。
◇It was him that we met at the school gate.(强调宾语)我们在学校门口见到的是他。
◇It was at three o'clock that we finished the work(强调状语)我们是在三点钟完成工作的。
★ 2、who/that的选用强调句中，引导词一般用that，that只起连接作用，没有实际意义，而且不能够省略掉。
指人时，that可以用who替代，其他情况下均用that。
◇It is our parents who/that we depend on when we are in trouble.当我们遇到困难时是我们的父母值得依靠。
（所强调的是人，所以who和that都可以用）◇It is a wallet that he picked up.他捡起来的是一个钱包。
（所强调的wallet是物，只能用that）3、is/was的选用原句谓语动词是过去的某种时态时，被强调部分用“It was...”；原句为现在的某种时态时，被强调部分用“It is...”。
4、主谓一致强调句中被强调部分如果是句子的主语，that/who之后的谓语动词在人称和数词上应与被强调的主语保持一致。
◇It is you whoare in charge of it.是你应该为此负责。
◇It is I who am to blame for the fault.是我应该因这个过失而受责备。
辨析：强调句和其他从句的区别一般来说，如果把句子中的It is/was ...that/who...去掉后稍加调整语序，能还原成完整的句子，并且句子意思依然完整，则为强调句。
It在强调句中的用法考点透视
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。

1. 被强调的成分举例：原句：Tom found my pen in the classroom yesterday.强调主语：It was Tom who / that found my pen in the classroom yesterday.强调宾语：It was my pen that Tom found in the classroom yesterday.强调地点状语：It was in the classroom that Tom found my pen yesterday.强调时间状语：It was yesterday that Tom found my pen in the classroom.2. 强调句型的一般疑问式：直接把is或was提到it之前即可。

强调句式强调状语的五种类型
强调句式强调状语的五种类型强调句式强调状语的五种类型强调句式It is (was)…that (who)…是英语中一个很有用的结构，也是各类英语考试的一个重要考点。
综合起来看，这类考点主要涉及强调状语的用法，而这类用法归纳起来主要有以下五类。
一、所强调的状语为单个的副词能用于强调句被强调的副词很多，下面略举几例：It was here that he differed from an Englishman. 他和英国人的不同就在于此。
It was only then that I began to learn the unpalatable truth ab out John. 直到那时我才开始了解到有关约翰的一些令人难以接受的实情。
It was yesterday that my secretary sent the bill to Mr Harding. 我的秘书是在昨天把账单送给哈丁先生的。
二、所强调的状语为副词性短语所谓副词性短语，就是指起副词作用可用状语的短语，如last week, so me time ago, three days later等。
如：It was about 600 years ago that the first clock with a face and an hour hand was made. 第一面带有一个钟面和一根时针的钟是在大约60 0年前制造的。
It was only last February that he announced he would run for p resident. 去年2月他才宣布自己将参加总统竞选。
It was last night that John wore his best suit to the dance. 约翰是昨晚穿着他最好的衣服去参加舞会的。
三、所强调的状语为介词短语介词短语的最主要功能就是用作状语，所以在强调句中，强调用作状语的介词短语的现象十分普遍。

“It is (was) … that(who)…”结构的强调句
“It is (was) …that(who)…”结构的强调句1。
此强调结构的重要特征“强调"就是使句子的某一部分比一般情况下显得更加重要。
英语表达中，强调句子的某一成分，一般可用强调句型“It is （was）+that (who）+句子的其余部分”。
这种强调结构也是英语高中里最常见的强调句语法考查。
此强调结构最重要的特征是it在句中无具体指代意义，只起引出被强调部分的作用,并且去掉强调结构“It is （was）… that(who）…"后，剩下的句子部分仍能组成一个意思完整的句子,这便是区别名词性从句和状语从句进而判断是不是强调句型的关键。
请认真揣摩下面一道高考原题:-—- Where did you get to know her? （07山东）-—- It was on the farm ____ we worked.A。
that B. there C. which D。
where答案D。
该句易误作强调句型，A是强干扰项。
这里where we worked 是定语从句，修饰the farm.It指“与她相识”这件事，有具体的指代意义，由此可知不是强调句.该题很容易受思维定势的影响误以为考察强调句。
而平时大家一再强调，用强调句型时即使强调地点状语，也不能用where而用that。
该句如果要用“it was… that”强调句型的话，可改写为“It was on the farm where we worked that I got to know her。
”2. 具体结构和具体注意点这种强调句的基本结构为“It +is(was）/should（could，might…) be+被强调部分+that/who（whom)/whose+句子的其他成分”。
如果被强调部分是人，用“that"，“who”，“whom"；如果被强调部分是物，用“that”或“which”；如果强调状语时，也只能用“that”, 不能“when"，“where”和“why"。

在做强调句练习时，需要注意：
