强调句型与定语从句地区别
强调句及定语从句及名词性从句的区分
强调句及定语从句及名词性从句的区分作者：李艳丽来源：《新一代》2013年第11期摘要：在英语学习中由it is…that引导的句型结构，常可构成强调句或定语从句，名词性从句，三者极易混淆。
这三种句性非常重要，是掌握的一大难点。
这几种从句有一的相似性，不少学生难以分清，常常误用。
本文着重研究这几种从句的相似性及不同点，分析在各种语境下怎样正确使用强调句，定语从句和名词性从句。
关键词：强调句；定语从句；名词性从句中图分类号：G630 文献标识码：A 文章编号：1003-2851（2013）-11-0201-01知识点讲解1：强调句与定语从句的区分一般来说，如果将it is/was…与连接词去掉，句子仍然正确，就为强调句型。
这时，就选用that连接词；否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。
例（1）It is on the island that they spent 10 years.（2）It is the island where （on which） they spent 10 years.比较：（1）该句为强调句。
表示地点的名词the island前有介词与其连用，说明它是一个完整的地点状语。
如果将it is去掉：They spent 10 years on the island.它的意义仍然完整。
故应选用连接词that构成强调句式（注：强调地点状语时，不可用where连接）。
（2）该句为定语从句。
表示地点的名词the island前没有介词与其连用，说明它不是一个完整的地点状语。
如果将it is去掉：They spent 10 years the island.它的意义不完整。
故应选用关系副词where或on which 构成定语从句结构。
知识点讲解2：名词性从句与定语从句的区分所谓名词性从句包括：主语从句，宾语从句，表语从句，同位语从句。
那他们又是什么呢？我们知道一个完整的句子了要有主语谓语宾语，或者表语，同位语。
各类从句及强调句的结构和用法
各类从句及强调句的结构和用法定语从句：是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。
状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。
名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be 句型。
一、限定性定语从句1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。
而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置。
2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. where是关系副词，用来表示地点的定语从句6. when引导定语从句表示时间注意：值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to business trip, he brings a lot of living necessities, suchas towers, soap, toothbrush etc.7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody,something, anything, everything或nothing时，常用there is来引导二、非限定性定语从句非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时，that有时相当于inwhich, at which, for which或at whichAttitudes towards daydreaming are changing in much the same way that (in which)attitudes towards night dreaming have changed.人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

定语从句与同位语从句、强调句、状语从句的区别(汇编)
定语从句与同位语从句、强调句的区别一、定语从句1. 定语从句在句中做定语，修饰一个名词或代词，被修饰的名词、词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which；关系副词有：when, where, why。
2. 限制性定语从句与非限制性定语从句（1）限制性定语从句是先行词在意义上不可缺少的定语，用于修饰和限定先行词。
如果去掉，主句的意思就不完整或失去意义。
书写时不用逗号与先行词分开。
例：This is the boy who broke the window.（2）非限制性定语从句在意义上只是一个附加修饰语，对先行词或主句作些附加的说明。
如果去掉，主句的意思仍然清楚。
书写时往往用逗号与先行词分开。
例：I, who am your friend, will share the work with you.3. 非限制性定语从句的“四个不能”：（1）非限制性定语从句通常不能用that引导。
（2）非限制性定语从句不能用why引导，要用for which 代替。
例：I had told them the reason, for which I didn’t attend the meeting.（3）由“介词+关系代词”引导时，关系代词不能用as。
（4）指人的关系代词作宾语时用whom，不能省略。
4. 在定语从句中，下列情况的关系词用that而不用which:（1）先行词被形容词最高级、序数词、数词等几种词修饰或被only, any, few, little, no, all, one of等修饰时。
例：This is the best film that I have ever read.（2）先行词为all, much, little, none, few, one, something, everything, anything等不定代词时。
定语从句和强调句的区分方法
定语从句和强调句的区分方法1.结构不同：定语从句是一个从句，通常修饰一个名词或代词，而强调句是一个完整的句子，用来强调一个句子成分。
例句：The book that I bought yesterday is very interesting.（定语从句）It is me who bought the book yesterday.（强调句）2. 位置不同：定语从句通常位于被修饰的名词或代词之后，而强调句则可位于句首、句中或句末，通常用it或者wh-词引导。
例句：The girl who is wearing a red dress is my sister.（定语从句）It is my sister who is wearing a red dress.（强调句）3. 关键词不同：定语从句通常使用关系词（如that, who, which等）引导，而强调句则使用it is...that...或者it is...who...等结构来强调句子的一些成分。
例句：The movie that I watched last night was amazing.（定语从句）It was the movie that I watched last night that was amazing.（强调句）4.强调的程度不同：定语从句主要用来限定名词或代词，使其更具体，而强调句则是为了给一些成分更多的强调和重要性。
例句：I have a friend who can play the guitar very well.（定语从句，强调的是我有一个会弹吉他的朋友）It is my friend who can play the guitar very well.（强调句，强调的是我的朋友会弹吉他）通过注意以上几个特点，可以帮助我们区分定语从句和强调句的语法结构和意义。
强调句与定语从句
强调句与定语从句篇一：强调句和各从句的区别一、定语从句与名词性从句句式结构用法比较定语从句常易与主语从句、表语从句、宾语从句和同位语从句等名词性从句相混淆。
判断的方法是：由关系代词或副词引起的句子直接充当句中某一成分，即为名词性从句；如果这个句子修饰前面的一个名词即先行词或指代整个句子的内容，即为定语从句。
例1. (1) As is known to everyone, the moon travels round the earth once every month.(2) It is known to everyone that the moon travels round the earth once every month.比较：(1)两个句子之间有连接词，而且由逗号分隔。
根据前一分句意义“正如大家所知道的(众所周知)”分析，该句应用关系代词as引导非限制性定语从句，指代主句整个句子内容。
(2)两个句子之间有连接词that连接。
根据句意分析，that所引起的从句为主语从句，故该句应选用it作形式主语置于句首，引导主语从句。
例2. (1)Shenzhen is no longer what it used to be.(2) Shenzhen is no longer the place that it used to be.比较：(1)句中没有充当表语的名词，故应选用代词what(??样子)引起一个表语从句。
(2)句中表语名词the place 被it used to be所修饰，且充当其句中表语。
故应选用关系代词that指代先行词the place引起一个定语从句。
例3. (1) Please tell me the reason why he didn’t attend the meeting.(2) Please tell me why he didn’t attend the meeting.比较：(1)句中充当宾语的名词the reason被he didn’t attend the meeting所修饰，且充当句中的原因状语。
强调句型与其他带有it的复合句型的区别
一、 与主语从句的区别。
强调句与主语从句虽然在形式上很相似，都含有it is / was... that... ,但是它们有一个很重要的区别，强调句去掉it is / was和 that之后，句子结构仍然完整，而主语从句却不能这样。试比较：
（1） it is the early bird that catches the worm.
3. ―it’s a long time ____ we met last.
―yes, and what a pity since it will be long _____ we see each other again.
a. since; that b. that; before
（3） it was around 100 years ago _____ the modern olympic games began to be held．
（4） it is around 100 years _____ the modern olympic games began to be held．

辨别强调句、定语从句、主语从句、状语从句
辨别强调句、定语从句、主语从句、状语从句（要点精讲）一、强调句与各从句的比较1．强调句与主语从句的比较强调句将句子中的It is/was … that同时省去，句子仍然成立；而主语从句不能。
如：(1)It was Tom that saw Jane at the movie theater yesterday. 是汤姆昨天在电影院见到简。
本句若将It was及that同时省去为：Tom saw Jane at the movie theater yesterday. 句子同样成立，因此该句是强调句。
(2)It is true that he is a man of few words.本句若将It is及that同时省去为：true he is a man of few words.，显然句子错误，因此，该句不是强调句，而是主语从句。
2．强调句与定语从句的比较(1)强调句中的It没有实际意义，It be与that同时去掉后句子仍然成立；而定语从句中的It be与that不可同时省略。
(2)在强调句中连接词只有that、who，并且不可以省略；而在定语从句中一般使用关系代词that，which，who，whom或关系副词when，where，why等，而that在从句中作宾语的时候可以省略。
(3)强调句中可以用副词、介词短语或从句来作被强调的内容；而定语从句的先行词（中心词）一般是名词或名词短语。
比较下列句子①It is on the island that they spent 10 years.②It is the island where (on which) they spent 10 years.解析：①表示地点的名词the island前有介词与其连用，说明它是一个完整的地点状语。
如果将it is及that去掉：They spent 10 years on the island.它的意义仍然完整。
高中英语强调句解析
高中英语强调句解析强调句（一）强调句句型1、陈述句的强调句型：I t i s/ w as +被强调部分（通常是主语、宾语或状语）+ t hat/ w ho（强调主语且主语指人可以用w ho,当然也可以使用t hat）+其它部分。
强调句式只是把句子中某些词(被强调部分)改变位置,所以把强调结构(i t i s/w as... t hat/w ho)去掉之后,句子一定是完整的e.g.It w as y es t e rd ay t hat he me t Li Pi ng.2、一般疑问句的强调句型：同上，只是把i s/w as提到i t前面。
e.g.Was i t y e s te rd ay t hat he me t Li P i ng?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）+ i s/ w as +i t+ t hat/w ho +其它部分？e.g.Whe n and w he re w as i t t hat y ou w e re born?4、强调句例句：I me t Li Mi ng at t he rai l w ay st at i on y e st e rd ay.强调主语：I t w as I t hat(w ho)me t Li Mi ng at t he rai l w ay s t ati on y e s te rd ay.强调宾语：I t w as Li Mi ng t hat I me t at t he rai l w ay st at i on y e st e rd ay.强调地点状语：I t w as at t he rai l w ay s t at i on t hat I met Li Mi ng y e st e rd ay.强调时间状语：I t w as y e st e rd ay t hat I me t Li Mi ng at t he rai l w ay st at i on.5、注意：构成强调句的i t本身没有词义；强调句中的连接词一般只用t hat, w ho，即使在强调时间状语和地点状语时也如此，t hat, w ho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。
强调句式
强调句练习其实强调句和定语从句非常相近，强调句主要看它的结构形式，；而定语从句则在从句中做成分,或者做主语，或者做宾语，或者状语。
eg. 正常句子：I met an old friend in the street on that Sunday.强调句可以强调1）主语2）宾语3）地点、时间、其他状语1) It was I who met an old friend in the street on that Sunday.2)It was an old friend that I met in the street on that Sunday.3) It was in the street that I met an old friend on that Sunday.4) It was on that Sunday that I met an old friend in the street.*强调主语时，指的是人时，不用that,而用who。
其他全用that.**It is/was ...that ... 去掉时，原来的句子能回去。
eg. It was eight o'clock when we arrived.=we arrived at 8.It was at eight that we arrived.这两个句子其实是完全不一样的。
前者是定语从句；后者则是强调句。
把It was...that去掉能不能回去是关键。
下列是典型的强调句：It was not until the night that....It was what you said that....It was with great joy that....It was only with your help that...It was for the reason that....一般疑问句式：Is /Was it ........that.......?特殊疑问句式：疑问词+is /was it ........that.......?1.Were all three people in the car injured in the accident?No,___ only the two passengers who got hurt.A. it wasB. there isC. it wereD. there was2. ---Who is making so much noise in the garden? --- ___ the children.A.

强调句和各从句的区别
一、定语从句与名词性从句句式结构用法比较 定语从句常易与主语从句、表语从句、宾语从句和同位语从句等名词性从句相混淆。
判断的方法是：由关系代词或副词引起的句子直接充当句中某一成分，即为名词性从句；如果这个句子修饰前面的一个名词即先行词或指代整个句子的内容，即为定语从句。
例1. (1) As is known to everyone, the moon travels round the earth once every month. (2) It is known to everyone that the moon travels round the earth once every month. 比较：(1)两个句子之间有连接词，而且由逗号分隔。
根据前一分句意义“正如大家所知道的(众所周知)”分析，该句应用关系代词as引导非限制性定语从句，指代主句整个句子内容。
(2)两个句子之间有连接词that连接。
根据句意分析，that所引起的从句为主语从句，故该句应选用it作形式主语置于句首，引导主语从句。
例2. (1)Shenzhen is no longer what it used to be. (2) Shenzhen is no longer the place that it used to be. 比较：(1)句中没有充当表语的名词，故应选用代词what(……样子)引起一个表语从句。
(2)句中表语名词the place 被it used to be所修饰，且充当其句中表语。
故应选用关系代词that指代先行词the place引起一个定语从句。
例3. (1) Please tell me the reason why he didn't attend the meeting. (2) Please tell me why he didn't attend the meeting. 比较：(1)句中充当宾语的名词the reason被he didn't attend the meeting所修饰，且充当句中的原因状语。
高中语法-强调句
强调句一：考纲解读：在高考中，有关注对语言形式的考查，特别是对强调句的考查，这类题目的综合性和情节性将会变得越来越强。
从近五年高考的趋势来看，倒装句和强调句占考核内容的53%。
因此必须加强语法专项练习，以确保记忆的准确和全面。
二：考点梳理：1）强调除谓语以外的句子成分的强调句：it强调句构成：It+be（只能是单数形式）+被强调部分+that(强调部分指人做主语时用who，指人做宾语时用whom)+句子的其他部分。
Mary met an old beggar in the street yesterday.It was Mary who/that met an old beggar in the street yesterday.(强调主语)It was an old beggar whom/that Mary met in the street yesterday.(强调宾语)It was yesterday that Mary met an old beggar in the street.(强调时间状语)It was in the street that Mary met an old beggar yesterday.(强调地点状语)注意：（1）it强调句型不能强调句子的谓语。
（2）主谓一致：被强调部分作主语时，其形式与谓语动词在人称和数上保持一致。
It is your father who is wrong this time.It is his parents who have come to China.（3）人称照应：强调主语用主格，强调宾语用宾格。
It is I who am wrong.It was her whom I saw in the street just now.（4）be前面可加情态动词。
It must be Peter who has let this secret out.It may be next week that she leaves for Tokyo.It might be last night that the thief broke in their house.问句形式：一般问句：Is/Was it + 被强调部分+ that + 其他成分Is it the dictionary that you are looking for?Was it yesterday that he was fired?特殊问句：疑问词+is/was +it +that +其他成分(用陈述语序)What is it that you want me to do ?Who was it that told you the news?When was it that you called me?How was it that you succeed?2）强调谓语的强调句：用助动词“do（does／did）＋动词原形”来表示强调：He does know the place well．他的确很熟悉这个地方。
强调句型与定语从句的区别
强调句型与定语从句的区别大家都知道，在高中英语学习中，强调句型和定语从句是高中英语中一个重要的语法项目，是高考重要考点之一。
学生在学习的过程中往往容易将两者混淆。
强调句(The Emphatic Pattern) 是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。
通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。
英语常用的强调结构有：It is (was)+被强调部分(主语、宾语或状语)+that/who...；定语从句（Attributive Clauses）在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出.如：例句1.（It's ）in the house （that）he lives.（强调句型）例句2.It's the house where he lives.（定语从句）那么，如何来判断这两个句子呢？下面我就上面的例句进行分析，并作以区别。
结合学生在做题中所遇到的问题对强调句和定语从句进行区别：由it引导的句型结构，常可构成强调句或定语从句，两者极易混淆。
一般来说，如果将it is/was...与连接词去掉，句子仍然正确，就为强调句型。
这时，就选用that连接词;否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。
例句1.It's in the house that he lives.去掉后是：（It's ）in thehouse（that）he lives.=He lives in the house.例句2.It's the house where he lives.（不能是that）否则去掉后是：He lives the house.很明显这是错误的。
比较：(1)该句为强调句。
表示地点的名词the house前有介词与其连用，说明它是一个完整的地点状语。
(完整版)定语从句、同位语从句和强调句
必修二Unit1定语从句、同位语从句和强调句➢定语从句和同为语从句的区别1.从词类上区别同位语从句前面的名词只能是idea, fact, news, hope, belief， suggestion， proposal, word，thought， doubt， truth， possibility, promise， order等表示抽象意义的名词。
而定语从句的先行词可以是名词、代词、主句的一部分或整个主句。
如:We are looking into the question whether he is worth trusting.我们正在调查的是他是否值得信赖的问题。
（同位语从句）Word came that he had gone abroad.据说他已经出国了。
(同位语从句）The doctor whom you are looking for is in the room.你找的那位医生在房间里面。
(定语从句,名词the doctor作先行词）Our team has won the game， which makes us very happy.（定语从句，which代表前面提到的整个句子）His mother did all she could to help him with his study.他妈妈尽最大努力帮他学习。
（定语从句，代词all作先行词）2.从性质上区别定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。
如：The news that our team has won the game is true。
我们队赢了那场比赛的消息是真的。
(同位语从句，补充说明news的内容。
）The news （that） he told me yesterday is true。
昨天他告诉我的那个消息是真的。

强调句与定语从句
强调句与定语从句强调句与定语从句强调句与定语从句有不同呢?下面是店铺整理的强调句与定语从句，欢迎大家阅读参考，希望帮助到大家。
【定语从句】一、基本定义定语从句，一个简单句跟在一名词或代词后(先行词)进行修饰限定，就叫做定语从句。
在主句中充当定语成分。
被修饰的词叫先行词。
定语从句不同于单词作定语的情况，它通常只能放在被修饰的词(即先行词)之后。
定语从句由关系词(关系代词、关系副词)引导，关系代词、关系副词位于定语从句句首。
1、定语从句的引导词一共有9个：who, whom , whose, that, which, when,where, why, as与名词从句相比：定从不能由what和how引导;which的含义改变;定从内部的介词可以放引导词前。
2、引导词的功能有哪些?(1)引导定语从句(2)代替先行词在定语从句中充当一个成分。
(先行词在从句中不再出现)二、从句结构1、先行词指被定语从句修饰的名词、代词或句子。
一般先行词出现在定语从句的前面。
2、关系词关系词常有3个作用：①连接作用，连接主句和定语从句。
②指代先行词。
③在定语从句中担当成分。
注：关系代词有主语、宾语、定语之分。
一般who做主语或其宾格形式的whom做宾语(whom作宾语时可省略)，whose作为定语(whose不可省略)。
关系代词在从句中作主语，宾语，定语等，关系副词在从句中作地点状语(where)，时间状语(when)，原因状语(why)。
3、定语定语用来限定、修饰名词或代词，是对名词或代词起修饰、限定作用的词、短语(动词不定式短语、动名词表示的)汉语中常用“……的”表示。
主要由形容词担任，此外，名词、代词、数词、分词、副词、不定式以及介词短语也可以来担任，也可以由一个句子来担任。
单词作定语时通常放在它所修饰的词之前，作前置定语。
短语、从句作定语时则放在所修饰的词之后，作后置定语。
被定语从句修饰的名词、代词称为先行词。
如“the girl”，“the book”如:She is the girl who likes singing. 她就是那个喜欢唱歌的女孩。

强调句与定语从句区别
强调句与定语从句区别强调句与定语从句区别强调句与定语从句的区别是什么?大家知道吗?以下是店铺精心整理的强调句与定语从句区别，仅供参考，欢迎大家阅读。
知识点讲解1：强调句及强调句与定语从句的区分首先我们来看下面这道题：“Where did you find the professor who made the speech yesterday?” “It was in the hall ______ the students often have a meeting.”A. whereB. whichC. thatD. when<陷阱>很可能误选C，认为这是一个强调句，强调地点状语in the hall。
<分析>假若选C，即有It was in the hall that the students often have a meeting，该句的意思是“学生们通常是在大厅开会”，单独看这一句，无论是其意思还是其语法均未错，但若将其与上文联系起来看，则不通，因为上文的意思是“你是在哪儿找到昨天作报告的那位教授的?”假若将答句改为 It was in the hall that I found the professor，则完全可以。
其实，此题的最佳答案是A，where the students often have a meeting 为定语从句，用以修饰其前的名词the hall，句意为“是在学生们经常开会的那个大厅(找到教授的.)”，这样语意就通顺了。
定语从句与强调句句式结构用法比较：由it引导的句型结构，常可构成强调句或定语从句，两者极易混淆。
一般来说，如果将it is/was...与连接词去掉，句子仍然正确，就为强调句型。
这时，就选用that连接词;否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。
例1. (1) It is on the island that they spent 10 years.(2) It is the island where (on which) they spent 10 years.比较：(1)该句为强调句。

强调句型与定语从句的区别
大家都知道，在高中英语学习中，强调句型和定语从句是高中英语中一个重要的语法项目，是高考重要考点之一。
学生在学习的过程中往往容易将两者混淆。
强调句 (The Emphatic Pattern) 是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。
通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。
英语常用的强调结构有：It is (was)+被强调部分(主语、宾语或状语)+that/who...；定语从句（Attributive Clauses）在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出.如：
例句1.（It's ）in the house （that） he lives.（强调句型）
例句2.It's the house where he lives.（定语从句）那么，如何来判断这两个句子呢？下面我就上面的例句进行分析，并作以区别。
结合学生在做题中所遇到的问题对强调句和定语从句进行区别：由it引导的句型结构，常可构成强调句或定语从句，两者极易混淆。
一般来说，如果将it is/was...与连接词去掉，句子仍然正确，就为强调句型。
这时，就选用that连接词;否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。
例句1.It's in the house that he lives.去掉后是：（It's ）in the house（that） he lives.=He lives in the house. 例句2.It's the house where he lives.（不能是that）否则去掉后是：He lives the house.很明显这是错误的。
比较：(1)该句为强调句。
表示地点的名词the house 前有介词与其连用，说明它是一个完整的地点状语。
如果将it is去掉：He lives in the house.它的意义仍然完整。
故应选用连接词that构成强调句式 (注：强调地点状语时，不可用where连接)。
(2)该句为定语从句。
表示地点的名词the house前没有介词与其连用，说明它不是一个完整的地点状语。
如果将it is去掉：He lives the house..它的意义不完整。
故应选用关系副词where或in which 构成定语从句结构。
我们再来分析一组例句：
例3.It is on the date that she went abroad.
例4.It is the date when (on which) she went abroad.
比较：例3分析句子结构可知，在表示时间的名词the date 前有介词与其连用，说明它是一个完整的时间状语。
如果将it is去掉：She went abroad on the date.它的意义仍然完整。
故应选用连接词that构成强调句式(强调时间状语时，不可用when连接)。
例4分析句子结构可知，在表示时间的名词the date 前没有介词与其连用，说明它不是
一个完整的时间状语。
如果将it is去掉：She went abroad the date.它的意义不完整。
故应选用关系副词when或on which 构成定语从句结构。
但是在高考对于语法进行细致考察的考试中，则出现了这样一个问题：强调句型易与定于从句混淆，导致解题出错。
的确，“that”也是一个定语从句重要的关系词，且两者句子形式有时也十分相似。
这里以一个高考试题为例：例句5.It is 3:00 o’clock___ we have the meeting.
A that
B when
C in which
D where
选项的问题集中在A\B两个选项上。
换言之，解题的关键是判断这个句子到底是强调句还是定语从句。
而这里有一个简单的方法供大家参考：如果将句子中的“it is…that…”部分去掉后，句子仍保持完整，则这是一个强调句型。
反之则是定语从句。
在上面的例子中，去掉“it is…that”这个部分后，句子转换成 we have the meeting 3:00 o’clock. 不难看出，这是个不完整的句子。
3:00 o’clock前需要一个介词“at”。
因此可以将其判断为定语从句，选择B选项 when.
如果这个句子是强调句型，则应该写作：“it is at 3:00 o’clock that we have a meeting.” 去掉“it is…that…”后句子变为“ we have a meeting at 3:00 o’clok.”仍能保持完整。
强调句型无疑是英语众多特殊句型中最为简单的一种：单纯的“it is__ that____”结构。
只需要将被强调的部分放在“be”动词与“that”之间，其余的部分依次写在“that”之后就可以轻松构成强调句型，并能强调句子中除谓语动词意外的任何成分。
例句 6.It was in the small house _________ was built with stones by his father _________ he spent his childhood.
A. which, that
B. that, which
C. which, which
D. that, where
答案选A，填对此句的关键是要弄清第二空必须填that，因为这是一个强调句，被强调部分为 in the small house (以及修饰它的定语从句which was built with stones by his father)。
又如：
例句7(1) It was the boy _________ had been in prison _________ stole the money.
A. who, where
B. that, how
C. who, that
D. that, which
【分析】此题答案选C，全句为强调句，被强调成分是the boy (以及修饰它的定语从句who had been in prison)。
(2) It was just in the room _________ he was born _________ he died.
A. where, which
B. that, that
C. where, that
D. which, that
【分析】此题答案选C，全句为强调句，被强调成分是in this room，where he was born 为修饰 the room 的定语从句。
强调句型不仅在各类考试的阅读文章量出现，并且如果能够熟练运用于口语和写作考试的话，还可以增加句型的多样性，使文章灵活多变，句意重点突出。
是一种易于掌握且用途广泛的句型。
13. You are waiting at a wrong place. It is at the hotel ____ the coach picks up tourists.卷2016
A. who
B. which
C. where
D. that。
