2．句型解读：
(1) it是引导词，强调的内容可以是句子的主语、宾语、状语。如果被强调的部分是人，that 可用who代替，其他情况一律用that。
(2) 验证强调句的方法：去掉It is / was…that 结构后，可以把被强调的部分与句子其余部分还原为一个完整的句子。

【例句观察】
(1) It was Edison who invented the lamp.
(2) It is Edison who invents the lamp.

【结论2】当被强调的部分是主语时，注意保持主谓一致。
【例句观察】

→ It wasn't until he finished his homework that he went to bed. (强调句)
【结论3】not …until …结构用于强调句中，not 要提前到until之前，放在be动词后。即：It wasn't until …that ＋句子的其余部分。
【例句观察】
Was it not until he finished his homework that he went to bed?
【结论4】强调句的一般疑问句形式：Is / Was it ＋被强调部分＋that＋句子的其余部分。【完成句子】
When was it that he went to bed?
【结论5】强调句的特殊疑问句形式：特殊疑问词＋is / was it＋that ＋句子的其余部分。【例句观察】
I really don't know when it was that he went to bed.
【结论6】含有强调句型的特殊疑问句作宾语从句时，注意用陈述语序。
【疑难】It is in the city where he was born that he works.
他工作的地方是他出生的那个城市。
【疑难剖析】强调句中的被强调部分含有一个定语从句，要注意区别、分析。
It is / was ＋被强调部分＋定语从句＋that (who)＋句子的其余部分
It的用法（专项总结及训练） 一、人称代词 1，it的最基本用法是作代词，主要指刚提到的事物，以避免重复: ①They watched the train until it disappeared in the distance. 2.，也可以指动物或婴儿(未知性别的婴儿或孩子): ②Is this your dog？No, it isn’t. ③They got a baby and it was a ten-pounder 3.，也可指抽象事物或指抽象环境和情景: ③I hate it when people talk with a full mouth.． 二、.非人称代词 1.it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： ⑴.指天气：It is a lovely day, isn’t it? ⑵.指时间: It was nearly midnight when she came back. ⑶.指日期:It is April First today. ⑷.指距离:It is some 3000 kilometers from Beijing to Guangzhou. ⑸.指价值:It is three dollars. ⑹.指温度:Today it is 30 degrees centigrade. 三、其他用法 1.在句子的主语不太明确时充当主语，表示谁在做某事： ①Who is it there?

(不用she). “---肯定是李红。” 比较：---Who is that girl？“---那个女孩是谁？” ---She is Li Hong. “---她是李红。” 注：it作实义代词，代替前面提到过的人、事、物。指代人时，常用于小孩或身份、性别不明的人。 2.Our computer is stolen.

He failed in the examine，which worried him. ⑵it用作非人称代词：常常用作句子的主语，可以指时间、距离、价格、长度、重量、日期、星期、月份、季节、气候等。 ⑶it用作形式主语或形式宾语：根据句子结构的需要，人们常用it作形式主语或宾语，而把真正的主语或宾语（不定式短语、动词-ing短语或名词性从句）放在句末。注意it作形式主语的常见结构有： ①It+ be + adj/n（for sb）to do sth. ②It +be + adj of sb to do sth. ③It +be + adj /n+ doing sth（一般限于名词fun，good，luck，joy，use，pleasure 或形容词foolish，wonderful，good，nice，interesting，useless，worth等作 表语时，才用it作形式主语，将真正的动名词主语后置） ④It +be + adj./n + that-clause. ⑤It +be+过去分词（如said，proved，known，believed，reported，thought，hoped， decided，announced, suggested，ordered，demanded，proposed，requested，advised 等）+that-clause.注意如果表语是划线部分的词，从句应该用虚拟语气。 ⑥It takes sb some time to do sth. ⑦It seems/looks as if…. ⑷it用在强调句型中： 强调句型“It is/was + 被强调部分 + 其他”的用法 ①这一句型可以强调除谓语、表语、定语和同位语以外的任何部分；如果被强调的部分是人，可以用who/that，如果被强调的部分是事物，只能用that。如：It was I who/that came here late this morning. It is a book that is on the desk. ②注意该句型不能强调让步状语从句；强调原因状语从句时，只能用because，不能用

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。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) 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. 6. It is suggested ( ordered ... ) that ... 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 off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) 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. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ... 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 / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 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 / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen .

“it” 两项重点用法Mar 4. 2011 这两项重点用法指的是强调句和it做形式成分。 一.强调句: 一）陈述句： It + is / was + 被强调部分+ that / who … ( 强调人时可用who ) I met Tom in the street yesterday. 针对各个划线部分变强调句： 1) It was I that met Tom in the street yesterday. 2) It was Tom that I met in the street yesterday. 3) It was in the street that I met Tom yesterday. 4) It was yesterday that I met Tom in the street. 二）一般疑问句： 1) Was it I that met Tom in the street yesterday? 2) Was it Tom that I met in the street yesterday? 3) Was it in the street that I met Tom yesterday? 4) Was it yesterday that I met Tom in the street? 三）特殊疑问句： 1) Who was it that met Tom in the street yesterday? 2) Who was it that I met in the street yesterday? 3) Where was it that I met Tom yesterday? 4) When was it that I met Tom in the street? 四）特殊疑问句作宾语从句： I forgot… 1) I forgot who it was that met Tom in the street yesterday. 2) I forgot who it was that I met in the street yesterday. 3) I forgot where it was that I met Tom yesterday. 4) I forgot when it was that I met Tom in the street. 结论：特殊疑问句作宾语从句时，主谓词序正常。 五）判断强调句的方法： “It is / was … that…” 这个框架拿掉以后，句子仍然成立。 高考题： I just wonder ___ that makes him so excited. A. why it does B. what he does C. how it is D. what it is （D ） 难点： I did not go to bed until midnight. It was not until midnight that I went to bed. 二. It 做形式成分：形式宾语和形式主语
It is……that强调句用法 当需要强调句中的主语、宾语、状语时，我们常用“It is(was)+被强调部分+that(who)”这种句型，使用此句型时，应注意以下几点。 1.一般情况用It is(was)……that…如： He read three books in the library yesterday. 我们分别可以强调主语、宾语、地点状语和时间状语。如： It was he who(that)read three books in the library yesterday. (强调主语) It was three books that he read in the library yesterday.(强调宾语) It was in the library that he read three books yesterday. (强调时间状语) 2.当被强调部分指人时，可用that，也可用who；指物时，只用that,如： It was Tom who(that)I met last week. It is a new bike that his brother wants to buy. 3.强调状语时，只用that,不用when、where.如： It is at 5 o'clock that the train will arrive. 4.被强调的部分是主语时，注意句子的谓语动词和被强调的主语保持一致。如：It is he who is late. It is they that were late. 5.一般疑问句的强调句为:Is (was) it + that…? 特殊疑问句为：特殊疑问词+ is (was) it +that…?结构。如： Was it ten years ago that his father died?（他的父亲是十年前去世的吗？）When is it that you will set off?（你到底什么时候出发？） 6.注意在强调句的疑问句型中，强调标志that/who后只能使用陈述语序。 比较：Was it by plane that did he come back ?(×) Was it by plane that he came back? (√) When was it that the Second World War broke out? (√) When was it that did the Second World War break out ?(×) 7.强调时间状语和地点状语时与定语从句的区别： It was in 1921 that our Party was founded.(强调句式) It was 1921 when our Party was founded.(定语从句) 即：强调时间或地点时有介词置于其前时，则连接词用that。其前面应有介词而被省去时，则用连接词when（时间）或where(地点)。又如： It was on the farm that we practised planting crops. It was the farm where we learned a lot . 1
it在强调句中的使用 先看看这道题： __________ these boys that played tricks on their teachers. A. They were B. It were C. There were D. It was 【分析】此题应D。这是一个强调句型，其基本结构为： It is＋被强调部分＋that(who)＋其他 该句型应注意以下几点： 1.不管被强调部分是单数还是复数，其前一律用It is / It was，而不能用They are / There were之类的。 2.被强调部分是指人时，被强调部分后可用that / who，被强调部分指物时，被强调部分后只能用that。 3.被强调部分是指时间或地点时，被强调部分后通常用that，一般不用when，where之类的。 It is I who am right. 是我对。 It was you that were wrong. 是你错了。 It was in the Japan that he died. 他是死于日本。 It was yesterday that he got married. 他是昨天结婚的。 It was a computer that he bought last week. 他上个星期买的是一台电脑。 Where was it that she lived? 她是住在什么地方? When was it that he left for Japan? 他是什么时候离开去日本的? Who is it that teaches you English? 是谁教你们英语? 凸显文章亮点常用方法 写作时，如果仅局限在把内容交代清楚的水准上，只选用一些普通的、直截了当的词，或一律使用简单句平铺直叙，那么，这样写出来的文章就会像一碗白开水，呆板、单调，没有可读性。要使文章耐人寻味，有深度，同学们就应尝试使用一引起高级词汇或句型，以凸显文章的亮点，使文章增添文采，给读者(尤其是阅卷留下深刻印象)。具体说来，同学们可尝试以下方法： 一、灵活改变句子开头 在通常情况下，英语句子的排列方式为“主语+谓语+宾语”，即主语位于句子开头。但若根据情况适当改变句子的开头方式，比如使用倒状语或以状语开头等，会使文章增强表现力。如：
高中英语语法：It的用法 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。
