强调句与从句的比较

第一篇：强调句与从句的比较

强调句与从句的比较

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；而主语从句将that与后面部分代替it，成立。如：

(1)It is Li Lei’s brother that you met in the street yesterday.你昨天在街上所见到的就是李蕾的兄弟。

本句若将It is 及 that同时省去为：You met Li Lei’s brother in the street yesterday.句子同样成立，因此前面的句子是强调句型。

(2)It is exciting that we have succeeded in sending up Shenzhou V.我们成功地发射了神舟五号这件事情真令人兴奋。

本句若将It is 及 that同时省去为：We have succeeded exciting in sending up Shenzhou V.显然句子错误，因此，前面句子不是强调句型，而是主语从句。

2.强调句与定语从句的比较

◎强调句中的It没有实际意义，It be与that可同时被省略；而定语从句中的It是主语，It be与that不可同时省略；

◎强调句型中be的时态须跟后面句子的时态相一致；而定语从句中主句谓语动词be的时态须由主句的时间确定；

◎强调句将句子中的that不能省略，并且即使前面的名词是事物时，也不能将that换成which；而定语从句中的that作宾语时可被省略，并且当先行词是事物时可用which代替。

◎当it be后面的时间、地点名词作主语、宾语或表语时，引导词可用that / which；而作其他成分时，引导词须用when / which。如：

(1)It is an English book(that / which)I bought yesterday.它是我昨天买的书。(本句是对What is that?问句的回答，that所引导的是定语从句，that可被省略)

It was the English book that I bought yesterday.昨天我所卖的就是这本书。(本句相当于对I bought the English book yesterday中an English book进行强调)

(2)It was a room where we used to have meetings.它是我们过去常在开会的房子。(where 所引导的从句对前面的room进行说明，它是定语从句)It was in the room that we used to have meetings.过去我们开会就在这间房子里。(in the room是被强调的部分，本句是强调句型)

(3)It is a day when the people celebrate their victory.这是人们庆祝他们的胜利的日子。(when所引导的从句对a day进行说明，是定语从句)It was on that day that people celebrated their victory.就在那一天，人们庆祝了他们的胜利。(强调on October 1, 1949)

3．强调句与状语从句的比较

◎状语从句句首的It本身就是句子的主语；而强调句首的It不作任何成分也没有实际意义。

◎状语从句的连接副词that及句子前面的It be不能去掉。

◎状语从句的引导词可以是when / where，而强调句型中的that不能用其他词代替。如：

(1)It is such an interesting book that we all like it very much.它是一本如此有趣的书，我们大家都非常喜欢。(结果状语主从复合句)

It is such an interesting book that we all like very much.我们大家都非常喜欢的就是一本如此有趣的书。(强调such an interesting book)

(比较：It is such an interesting book as we all like very much.这就是我们大家都非常喜欢的如此有趣的书。定语从句)(2)It was already morning when he woke up.当他醒来时，已经是早晨了。(时间主从复合句)It was the next morning that he woke up.就在第二天早晨他醒来了。(强调the next morning)

第二篇：定语从句与同位语从句、强调句、状语从句的区别

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。

例：He told me everything that he knows.（3）先行词中既有人又有物时。

例：He was looking pleasantly at the children and parcels that filled his bus.（4）先行词在主句中作表语或关系词在定语从句中作表语时。例：The village is no longer the one that was 5 years ago.（5）当主句中含有疑问词which时；或者句中已经有who或which，为了避免重复时。

例：Which are the books that you bought for me ? 5.其他注意事项

（1）当the way做先行词时，只用that, in which或不用关系词。例：What surprised me was not what he said but the way he said it.（2）在限制性定语从句中，名词前有such和the same修饰时，关系代词用as不能用which。例：Don’t read such books as you can’t understand.（3）在非限制性定语从句中，as和which都可以指代前面整个主句。如果有“正如，像”的含义，可以 放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。例：They won the game, as we had expected.They won the game, which we hadn’t expected.6.定语从句与先行词被分割开来的现象

定语从句一般紧接被它所修饰的先行词；但有时候它和先行词之间有可能插入其他成分，使它与先行词分隔开来，这种定语从句叫作被分隔的定语从句。在阅读文章时会经常遇到这种情况，阅读时要注意识别先行词的修饰对象。

（1）在定语从句加中插入语，常见的有：I think,I suppose,I guess,I imagine等。辨别的方法是：去掉插入 语后，原句句法结构仍然完整。

例：He made another wonderful discovery,which I think isof importance to science.（2）在先行词与定语从句之间插入一个状语。

例：There are many thousands of stars in the sky that are like the sun.（3）在先行词与定语从句之间插入一个定语。

例：Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace? 你还记得吗，十年前的一天下午，我来到你家，找你借了一条钻石项链？

（4）先行词与定语从句被谓语分隔开来。此时，先行词通常是句子的主语，因定语从句较长，主句谓语

较短，为使句子平衡，常将定语从句移至谓语之后。例：A new master will come tomorrow who will teach you German.7.几个特殊的定语从句句型

（1）He is the only one of the students who has got very good marks in the match.（句中one为先行词）He is one of the students who have got good marks in the match.（句中students为先行词）（2）Is this place the one(that)we visited yesterday?（句中the one为先行词）Is this the place(that / which)we visited yesterday ?（句中 the place为先行词）（3）He stood at the window,from where he could see what was happening.（4）It may rain, in which case the match will be put off.8.定语从句的做题方法：（1）找出主句，确定先行词；

（2）找出从句，判断从句是否完整（是否符合简单句的基本构成）---否，用关系代词；是，用关系副词。

二、同位语从句

1.同位语从句就是在复合句中作名词的同位语的名词性从句。

同位语从句对名词进一步解释，说明名词的具体内容，一般由that引导，而且不能省略。例：The king’s decision that the prisoner would be set free surprised all the people.2.同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例：He got the news from Mary that the sports meeting was put off.三、定语从句与同位语从句的区别

1.定语从句中的that既代替先行词，同时可以在从句中作某个成分（主语或宾语）；而同位语从句中的that 是连词，只起连接主句与从句的作用，不充当句中任何成分。

2.定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述先行词的性质或特征；同位语 从句是名词性的，其功能是对名词进行补充说明。

例：The news that he told me is that Tom would go abroad next year.第一个that引导的从句是定语从句，that在从句中作宾语。The news that Tom would go abroad is told by him.同位语从句，that在句中不作任何成分，用于说明news的内容。

【注意】当主句的谓语部分过短时而从句过长时，同位语从句放在谓语动词的后面，避免头重脚轻。例：Word came that our team had won the game.四、定语从句与状语从句的区别

1.定语从句的前面有名词作先行词，而状语从句没有先行词。

例：This is the place where we used to live a few years ago.这是几年前我们居住的地方。（定语从句，先行词为the place）Let’s go where we can find a better job.我们到能找到更好的工作的地方去吧。（地点状语从句）

2.定语从句修饰、限制、说明名词，只能放在先行词的后面，而状语从句说明动作发生的情况，并且可以 放在主句的前面。

例：Do you know the time when the class is over? 你知道下课的时间吗？（定语从句）

When the class was over, it was already five o’clock.当下课时己经是5点了。（时间状语从句）3.When, where和why在引导定语从句时可以用“介词＋which”的结构来替换，在引导状语从句时却不行。例：This is the factory in which(where)his father once worked.这就是他的父亲曾经工作过的那个工厂。（定语从句）

Put back the book where it was.把书放回原处。（状语从句）

4.定语从句中的关系词在从句中充当某种句子成分，因此去掉它则从句成分不完整；而结果状语从句中的 连接词在从句中不作任何成分，去掉后从句的成分仍然完整。例：It is such an interesting book as we all like.as用作动词like的宾语，它引导的是定语从句。It is such an interesting book that we all like it.that不充当句子成分，故它引导的是结果状语从句。

五、强调句

1.强调句型的基本结构：It is/was + 被强调部分（主语、宾语、宾语补足语或状等）+ that/who +句子 的其余部分。

例：It was yesterday that Mary met an old beggar in the street.（强调时间状语）2.强调句中含有not until的句子

在强调not until句型时，not 位于until从句前，主句谓语动词作相应变化，即 itis(was)+not until +从句或者短语 +that+其它..例：It was not until he had finished the work that he went home.六、定语从句与强调句的区别

1.定语从句中关系词作从句成分，关系词作宾语时可省略；强调句中that / who没有任何意义且不能省略。

2.强调句中的it无意义，that / who不是引导词。

3.强调句it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。

例：It is the museum that / which we visited last year.（定语从句）It was in the hotel that we stayed last night.（强调句）

例题赏析：

1.There’s a feeling in me we’ll never know what a UFO is – not ever.A.that

B.which

C.of which

D.what 【解析】此题考查同位语从句that的用法。that引导同位语从句修饰a feeling，只是做补充成分而已。句 意是我内心有种感觉我们永远不会知道UFO是什么—从来也不知道。故此题选A.2.His uncle works in a factorybicycles are made． A.that B.which

C.where

D.there 【解析】此题考查定语从句关系副词的用法。bicycles are made in the factory, 此处缺少介词in,故需用关系

副词来引导，where相当于in which，因此选择C.练习

第四篇：英语强调句及it用法

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 …。

（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）

3、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）

第五篇：英语强调句小结

英语强调句小结

强调句子的方法有四种： I.倒装结构

1.用在以never, hardly, not only, nor, seldom, little, rarely, not until, hardly…when.no sooner …than 等表示否定意义或半否定意义的副词或词组开头的句子中。(1)No sooner had he gone to bed than he fell asleep.(2)Not only did Lincoln set the slaves free, he also reunited the nation.(3)Not until the early years of the 19th century did man know what the heat is.(4)Not until I began to work did I realize how much time I had wasted.(5)Not until all the fish died in the river did the villagers realize how serious the pollution was.2.表语提前，不仅可以表示强调，而且可使句子结构达到平衡协调，使带有较长修饰语

的主语放到句子的后部，以避免头重脚轻。

(6)Such is the little of our home in space when measured up against the total substance of the universe.3.从属连词as, however, though 等可引出强调让步状语从句，表示非常强烈的对照。(7)Busy as he always is, Bob never refuses to help others.(8)However late she is, mother will wait for him to have dinner together.4.当only与它所修饰的状语一起位于句首时，须用倒装语序，only起强调作用。其句形为“only + 状语+ 部分倒装语序”。

(9)Only in this way can you make progress in your English.II.It引出强调结构

1.为了强调句子的某个成分（主语，宾语，状语），常用强调结构：“It is(was)+被强调部分+that(who)…”。在强调句中作主句的主语。(10)It was at the gate that he told me the news.(11)Was it during the Second World War that he died?(12)It was about 600 years ago that the first clock with a face and an hour hand was made.It was only when I reread his poems recently that I began to appreciate their beauty.2.为了加强语气，我们可以将not until用在It be …that ,…”强调句型中，组成 “It be not until…that…” 结构，not 的否定功能仍不变，用来否定后面的谓语动词。(14)It was not until she took off her dark glasses that I realized she was a famous film star.(15)It was not until 1920 that regular radio broadcasts began 3.It is /was /will be(not)years /months/ weeks/ days/hours/minutes/seconds before….很就（不久）。。。才（就）。。

(16)It was not long before the policeman caught the thief.(17)I lost my job and it was several months before I found another one.III.双重否定结构

双重否定结构是由否定词not, never, nobody, nothing 等与带否定意义的词或词组相配

合而构成的。双重否定即否定的否定，实质是肯定，而且语气较为强烈。(18）One is never too old to learn.(19)I don’t think it possible to master a foreign language without much memory work.(20)Without knowledge of science and technology, it is impossible to build our country into a

strong and socialist country.(21)Unless he comes.We won’t be able to go.IV.Do(does/did)引出强调句

1.在肯定句的谓语动词之前（通常是现在时和过去时的肯定句），可用助动词do(does/did)来

强调动词,这时谓语动词须用原形动词。Do(does/did)可译成“确实”“的确”。(22)To my great joy， the plant did look exactly like what we were looking for.(23)He does work hard and finish the job in time.2.在肯定的祈使句中，用动词do来加强语气，可译成“务必，一定，千万”(24)Do come and see us some day.(25)Do give her my regards.
