五种强调句型 :怎么样分辨出英语强调句型
强调句是一种修辞,是人们为了表达自己的意愿或情感而使用的一种形式,下面简单归纳它的几种结构:
1.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。
Do
write
to
me
when
you
get
there.你到那儿后务必给我来信。
2.用形容词very,only,single,such等修饰名词或形容词来加强语气:

3.用ever,never,very,just等副词和badly,highly,really等带有-l

4.用in

be?他到底会在哪儿?

9.用If来表示强调:
1)If从句+I
don't
know
who/what,etc.does/is/has,etc.;主语部分也可以用nobody
does/is/has,etc.或everybody
does/is/has,et
c.来代替(这里的if从句往往是正话反说,反话正说):
If
he
can't
do
it,I
don't
know
who
can.要是他做不了这件事,我不知道还有谁能做。(强调只有他能做)
If
Jim

a
coward,everybody
is.要是吉姆是个胆小鬼,那么人人都是胆小鬼。(强调吉姆不是胆小鬼)
2)if从句+it
be主句(此用法可看成是第8中强调句型的变形,即把所要强调的内容放在it

If

truth,it
was
Tom.如果说谁了解事实的真相,那便是汤姆。
If

the
work

五种强调句型 :强调句型中时间和地点全用THAT而不能用WHENWHERE
句型结构:
It is / was + 被强调部分+ that / who /whom +句子剩余部分…
? 这个句型用来强调除谓语以外的各种句子成分,被强调部分必须放在it is/was 后面,如果强调的部分是人,可以who/whom 来代替that.
如:They will have a meeting in the hall tomorrow.
? 强调主语:
It is they that/who will have a meeting in the hall tomorrow.
? 强调宾语:
It is a meeting that they will have in the hall tomorrow
? 强调地点状语:
It is in the hall that they will have a meeting tomorrow
? 强调时间状语:
It is tomorrow that they will have a meeting in the hall.
强调句型是英语中常用句子结构,又是高考中的常见考点,其基本结构为:It + be+ 被强调部分+that+句子其余部分。现将其用法归纳如下:
1. 强调句型中,能够被强调的句子成分通常为主语、状语、宾语等,不能用来强调谓语动词、表语、补语、让步状语、条件状语等。
例如 It was in the park that I mat my old teacher yesterday. (强调地点状语)
It is Mr. Smith that thinks Tom is a clever boy. (强调主语)
2. 强调句型中,连接词一般用that,如被强调的部分是人,也可用who/whom,其他一律用that,不能用which, where, when等,即使被强调的是物、时间状语或地点状语。
例如 It was at the gate that we met the inspectors this morning.
It is our head-teacher that/ who/whom we often turn to for help.
3. 强调结构中,无论被强调的是人还是物,单数还是复数,be动词一律用单数is/was形式,如果原句的谓语动词是一般过去时,就用was; 是一般现在时,就用is。也可以用"情态动词+be"形式。
例如 It was the farmers that lived a hard life before liberation.
It might be yesterday that John bought a book for Mary.
4. 强调句型也有疑问句形式,包括一般疑问句、特殊疑问句和反意疑问句。一般疑问句的强调形式,只需将is/ was 提前,移至句首即可,即:Is/ Was it … that …。特殊疑问句的强调形式,须将陈述句变成一般疑问句,再在句首加上疑问词,即:疑问词(被强调部分)+is/was + it + that + 句子其余部分。
例如 Was it last year that the building was completed?
Where was it that you met your English teacher?
It was the day before yesterday that you lost the money, wasn't it?
5. not … until…结构在强调句型中的运用:until引导的时间状语从句,也可以用在强调句型中,但主要是其否定形式,如用在强调句型中,必须将not前移,写成It is/was not until … that … 。
例如 It was not until the class began that he came in.
It was not until last Friday that he finished reading the book.
6. 当强调的是主语时,其谓语动词应和被强调的人和物保持人称、数的一致。如果被强调的主语是人称代词,宜用主格,间或也可用宾格。
例如 It is I who am going to attend the meeting.
It was I/me who cleaned the classroom.
7. 强调句型最容易与定语从句、主语从句和状语从句一起考查,应是学习和复习的重点。一般说来,如果把句子中的It is/ was … that去掉,稍加调整语序,能还原成完整句子,并且句子意思依然完整,则为强调句型;否则,应为其他句式。
例如 It was a small house that I used to live in. (定语从句)
It was at the school gate that I met an old friend of mine.(强调句型)
高一册第19单元的语法重点是it在强调句型中的用法,这也是高考的重要考点。为了强调句子某一成分(除谓语外),将这一成分置于"It is (was)... that (who)..."这一句型中is (was) 之后,如果强调部分是人,既可用that又可用who连接,其余的全用that。这一句型也可用于一般疑问句、否定句和特殊疑问句。其特点是:去掉It is (was) 及 that (who)这几个标志词之后,在不添词、不减词的前提下能重新排列成一个完整的句子。现通过分析高考试题,体会it在强调句型中的用法,以期对同学们有所帮助。
英语中有时为了需要,经常要强调句子中的某一成分,这时,就要用到一些强调句型。英语中常见的用来表示强调的句型有以下几种。
一、用助动词do ,did does强调谓语。
用助动词do ,did does放在一般现在时和一般过去时的句子中动词原形前,以强调谓语。例如:
He did tell all that had happened to him. 他确实把发生的事情都说了。
She does get up early. 她的确常起得很早。
Do be careful next time. 下次务必要小心。
二、用倒装句来强调以加强语气。
Never have I seen such a wonderful film. 我从来没看过如此精彩的电影。
So hard did he study that he could easily pass the examination.
他那么努力才能轻易通过考试。
三、用 what来加强语气。
He needs money. 他所需要钱。
What he needs is money.他所需要的是钱。
Learning and knowledge are important to us, but what is more important is a noble character.学问和知识很重要,但更重要的是高尚的品格。
四、用in the world, on earth, at all等介词短语来表示强调,常用在疑问句中,与ever同义。
What in the world are you doing in my car? 你究竟在我的车里做什
么?
How on earth did she manage that? 她究竟怎么办到的呢?
Are you at all worried about the forecast? 对这项预报你不担点儿
心吗?
If you ever visit London, you must come and stay with us. 你要是
来伦敦,一定要来我们这来住住。
五、用形容词very, only, single, such等来修饰名词来表示强调。
This is the very thing I’m after. 这正是我要找的东西。
You are the only person here who can help us. 你是这儿唯一能帮我
们的人。
Not a single mistake did he make in the exam. 他在考试中没出一个
错。
六、用It is /was….that来强调主语,宾语,状语
用It is/was +被强调部分+that+句子的其他成分(如指人,that也可以用who, whom)来强调句子的主语,宾语,状语。
例如:I met him in the street this morning. 今天早上我在大街上遇到了他。
It was I who met him in the street this morning.(强调主语)
It was him that I met in the street this morning.(强调宾语)
It was in the street that I met him this morning.(强调地点状语)
It was this morning that I met him in the street.(强调时间状语)
It was because he was ill that he didn’t attend the meeting.(强调原因状语)
强调句型需要注意的几点:
1、如果原句中谓语动词使用的是现在范畴的时态(一般现在时、现在进行时、现在完成/现在完成进行时、一般将来时、将来进行时、将来完成时等)用It is…that 。如果原句中谓语动词为过去范畴的时态(一般过去时、过去进行时、过去完成时、过去将来时等)则用It was…that 。有时be前可以使用表示推测的情态动词构成结构。
It is not everyone that can draw well.不是每个人都能画得好的。
It was for his eyes that we asked him not to read in the sun.
我们是为他的眼睛着想才叫他不要在太阳下看书的。
It must be Jack who let out the secret.肯定是杰克泄露了秘密。
2、强调主语用人称代词主格,强调宾语用宾格。
It was I who gave you the book.(不用me)
It was I not him who am your best friend.(谓语与被强调词保持主谓
一致)
It was him that they telephoned.(强调宾语用宾格)
3、即使被强调成分是句子中的时间状语,地点状语,原因状语等,也
不能用when,where, because要用that.
(1) It was after the war was over that Einstein was able to come back to his research work again.
战争结束后爱因斯坦才能重新进行他的研究工作。
(2) It was in Athens that the 2004 Olympic Games were held. 2004
年奥运会是在雅典举行的。
(3) It was because of the traffic jam that the chairman cam late.主席是因为堵车才来迟的。
4、如果被强调的成分有同位语,同位语也应提前。
It was from him, our English teacher, that we learned this English
song.我们从英语老师那学会了这首歌。
5、Not until句型怎么强调?
当被强调的是not…until句型时,应将not置于until之前,主句由否定句改为肯定句。
We didn’t recognize her until she took off her glasses.
她把眼镜拿了,我们才认出她。
It was not until she took off her glasses that we recognized her.
注意与下面一句的区别:
Not until she took off her glasses did we recognize her.
此句为not位于句首,要主谓倒装。
6、疑问句中的强调句型。
其一般疑问句形式是:Is/Was it+被强调成分+who/that
其特殊疑问句形式是:疑问词+is/was+被强调成分+that...
Was it in the classroom that the meeting was held? 会议是在教室里
举行的吗?
Who was it that broke the vase? 是谁打碎了花瓶?
Why is it that you come to the party so late? 到底是为什么你这么晚来晚会?
7、与定语从句连用的强调句型。
Was it in the house where his grandfather once lived that they found the old picture?
他们是在他祖父曾经住过的房子里找到那张旧照片的吗?
--Where did you meet him? 你在那遇到他的?
--It was in the hotel where he stayed. 在他住的旅馆里。(本句后省略了that I met him)
8、与其他一些句型结构的区别。
(1)与状语从句的区别。
It was at 7 o’clock that I arrived. (强调句型,强调时间状语at 7 o’clock )
It was 7 o’clock when I arrived. (when时间状语从句。在7 o’clock前无介词at.)
It is three years since he came here. 自从他来这已经三年了。
It was not long before the fire was put out. 不久大火就被扑灭了。
(2)与主语从句的区别
It is true that he is honest. 他真的很诚实。
It is known to all that China is a country with a long history. 众所周知,中国是一个历史悠久的国家。
(3)与there be 句型的区别。
There is no possibility that Bob can win the first prize in the match..鲍勃没有可能在比赛中获得一等奖。
主要搞清楚的一点是:强调句型中去掉It is/was…that后仍然是一个完整的句子。而其他句型则不行。
英语中有时为了需要,经常要强调句子中的某一成分,这时,就要用到一些强调句型。
1、强调谓语。
用助动词do ,did does放在一般现在时和一般过去时的句子中动词原形前,以强调谓语。
例如:He did tell all that had happened to him.
She does get up early.
Do be careful next time.
2、强调主语,宾语,状语
用It is/was +被强调部分+that+句子的其他成分(如指人,也可以用who, whom)

It was I who met him in the street this morning.(强调主语)
It was him that I met in the street this morning.(强调宾语)
It was in the street that I met him this morning.(强调地点状语)

It was I who am your best friend.(谓语与被强调词保持主谓一致)
It was him that they telephoned.
2).与定语从句的区别。

3).与主语从句的区别

4).与其他句型的区别
It is three years since he came here.
It was not long before the fire was put out.
主要搞清的一点是:强调句型中去掉It is/was…that仍然是一个完整的句子。而其他句型则不行。
5).疑问句中的强调句型。
Was it in the classroom that the meeting was held?
Who was it that broke the vase?
It was Tom that broke the vase, wasn’t it ?

注意与下面一句的区别:
Not until she took off her glasses did we recognize her.
7).与定语从句连用的强调句型。
Was it in the house where his grandfather once lived that they found the old picture?
五种强调句型 :什么是强调句
基本语法 强调句是一种修辞,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是"It is (was)+被强调部分(主语、宾语或状语)+who (that)..."。一般说来,被强调部分指人时,用who;指事物时用that,但that也可以指人。在美国英语中指事物时常用which来代替that。
常用句型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)+ 其他部分。
例子 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。
例子 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 + 其他部分?
例子 When and where was it that you were born?
4.not … until … 句型的强调句
A. 句型为:It is/ was not until + 被强调部分 + that + 其他部分
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.
B. 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。
5.谓语动词的强调
A. 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
Do sit down. 务必请坐。
Do be careful when you cross the street. 过马路时,务必(千万)要小心啊!
B. 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。
3强调形式常见到的强调形式,共有以下七类:
⒈用do\does\did + V可表强调
Some people do believe that nuclear power poses a threat to the world peace.
⒉adv或adj可表强调:Never \ only\ Very
This is the very question that deserves careful analysis.
⒊双重否定可表强调
Taking part-time jobs is never without drawbacks.
⒋what引导的主从可表强调
What really matters is cooperation.
⒌倒装可表强调(凡是倒装都可以表示强调)
Little do people take into account the seriousness of this problem.
⒍比较状语从句可表强调
Nothing is more imperative than to learn from the past.
⒎强调句型可表强调
It is \was +被强调部份+ that \ who +原句剩余部份
It is stability that destroys people’s ambition and barricades people’s steps.
4语法结构强调句的十种结构:
1.用助动词“do(does/did)+动词原形”来表示强调:
Do write to me when you get there.你到那儿后务必给我来信。
2.用形容词very,only,single,such等修饰名词或形容词来加强语气:
How dare you buy such expensive jewels?你怎么敢买这么贵的宝石呢?
3.用ever,never,very,just等副词和badly,highly,really等带有-l y的副词来进行强调:
I really don’t know what to do next.我的确不知道下一步该怎么做。
4.用in the world,on earth,at all等介词短语可以表达更强的语气(常用于疑问句):
Where in the world could he be?他到底会在哪儿?
5.用感叹句来表示强烈的感情,突出说话人的情感:
How interesting a story it is!这是一个多么有趣的故事啊!
6.用重复来表示强调:
Why!why!The cage is empty!啊!啊!箱子是空的。
7.用倒装句(也就是将要强调的句子或被强调的部分置于句首)来加强语气:
On the table were some flowers.桌上摆着一些花。(强调地点)
8.用强调句型:“It is(was)+被强调的部分+that(who)+原句其它部分”来强调说话人的意愿:
It was on Monday night that all this happened.所有这一切发生在周一晚上。
9.用If来表示强调:
1)If从句+I don’t know who/what,etc.does/is/has,etc.
主语部分也可以用nobody does/is/has,etc.或everybody does/is/has,et c.来代替(这里的if从句往往是正话反说,反话正说):
If he can’t do it,I don’t know who can.要是他做不了这件事,我不知道还有谁能做。(强调只有他能做) If Jim is a coward,everybody is.要是吉姆是个胆小鬼,那么人人都是胆小鬼。(强调吉姆不是胆小鬼)
2)if从句+it be主句(此用法可看成是第8中强调句型的变形,即把所要强调的内容放在it be的后面,把其它内容放在由if引导的从句中):
If anyone knew the truth,it was Tom.如果说谁了解事实的真相,那便是汤姆。
10.用破折号、黑体字也可以表示强调,加强语气:
It’s because of hard work—ten years of hard work.那是因为艰苦的工作--十年艰苦的工作!
He began the work in late May.他在五月底开始的这项工作。(强调时间)
5注意事项that后的强调句如果是原因状语从句,从句只能用because引导,不能用since,as或why。
It was because the water had risen that they could not cross the river。

从句辨析 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。
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)
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)

五种强调句型 :如何正确判断强调句型
如何正确判断强调句型
英语强调句型的基本结构是“It+be+被强调成分+that (who)…”。在该结构中,It was…that (who)… 为强调句的结构词,原则上说,若将其去掉,句子意思依然清楚、结构依然完整。如:
1. It was Jack who stole our money. 是杰克偷了我们的钱。
若去掉it was…who…,即为:
Jack stole our money. 杰克偷了我们的钱。
2. It was in May that you can see this kind of flower. 你在五月可以看到这种花。
若去掉it was…that…,即为:
In May you can see this kind of flower. 你在五月可以看到这种花。
若去掉It was…that (who)…结构词,句子意思则不通、结构则不完整,那么就可能不是强调句。请看下面一题:
It was ten o’clock ________ he came back.
A. that B. when C. so D. which
许多同学以为这是考查强调句型,从而误选答案A。而其实此题最佳答案是B。因为这不是一个强调句型,假若去掉结构词it was…that…,句子则成了Ten o’clock he came back,此句要成立应在ten o’clock前加适当介词。如:
It was at ten o’clock that he came back. 他是10点钟回来的。
It was after ten o’clock that he came back. 他是在10点过后回来的。
It was before ten o’clock that he came back. 他是在10点前回来的。
It was ten o’clock when he came back 是一个包含有when引导的时间状语从句的复合句,全句意为“当他回来时,时间是10点钟”。
