强调句型是英语中常见句子结构,又是考试中的常见考点,

其基本结构为"It + be + 被强调部分 + that/who+句子其余部分",

具体用法:

1.强调句型可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(主语补语),让步状语,条件状语等;如:

It was in the park that I met my old teacher yesterday.(强调地点状语)

It was yesterday that I met my old teacher in the park.(强调时间状语)

It was my old teacher that I met in the park yesterday.(强调宾语)

It is Mr Smith who/that thinks Tom is a clever boy.(强调主语)

2.在强调句型中,连接词一般用that.如被强调的部分指人时,可用who(m)/that,其他一律用that,不能用which,where,when等

如: Where was it that you met your English teacher

It was the day before yesterday that you lost the money,wasn't it

3.在强调结构中,无论被强调的是人还是物,是单数还是复数,be动词一律用is/was形式,如果原句的谓语动词是一般过去时,就用was;如果是一般现在时,就用is.也可以用"情态动词+be"形式.如:

It is the monitor who wins the first prize in the exam.

It was the farmers who/that lived a hard life be fore liberation.

It might be yesterday that John bought a book for Mary.

It will be Xiao Wang who go with you.

4.强调句型也有疑问句形式.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".如:

Was it last year that the building was completed

How was it that he went to school

的哲理性,故常用一般现在时.例如:

It's a wise father who knows his own child.无论多聪明的父亲也不见得了解自己的孩子.

It's an ill wind that blows nobody(any)good.此失则彼得(没有使所有的人都受害的坏事).

5.not…until…结构在强调句型中的运用:until引导的时间状语从句中可以用在强调句型中,其结构为"It is/was not until…that…".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,但有时也可用宾格.如:

It is who am going to attend the meeting.

It is Tom who often helps me with my English.

It was I/me who cleaned the classroom.

7.强调结构还常常出现在谚语里,表示"无论怎样……都不……",是—种反语式的强调用法.这类句子往往含有一定

It was at the gate that we met the inspectors this morning.

It is our parents,that/whom we often turn to for help.

8.强调句型与定语从句,主语从句和状语从句的区别:

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,且句子意思依然完整,则为强调句型;否则,应为其他句式.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)

It was seven o'clock when we reached the mountain village.(时间状语从句)

It was at seven o'clock that we reached the mountain village.(强调句型)

It is a pity that you didn't see the film yesterday evening.(主语从句)

It is a good idea that we will have a swim this Sunday.(主语从句)

实例分析:

例1:It was __________ it was raining so hard that we had to stay at home all day.

A.since B.for C.as D.because

[析]答案D项.强调句型只可以强调由because引导的原因状语从句,as/since/for引导的句子不能用在强调句中.

例2:I can't quite remember __________ I was taken to Beijing.

A.that it was when B.when it was that

C.when was it that D.that was it when

[析]答案为B项.可以这样来分析:

假设原句为:I was taken to Beijing when I was a child.对时间状语进行强调,变成:It was when I was a child that I was taken to Beijing.再变成特殊疑问句:When was it that I was taken to Beijing 再放到宾语从句中:I can't remember when it was that I was taken to Beijing.

例3:It was the training __________ he had as a young man __________ made him such a good engineer.

A.what;that B.that;what C.that;which D.which;that

[析]答案为D项.本句强调的是主语the training,其后又服which引导的定语从句,还原后应为:The training which he had as a young man made him a good engineer.

例4:It was __________ he said and something he did __________ disappointed me at that time.

A.what;that;that B.that;what;that

C.what;what;that D.what;that;what

[析]答案为A项.此题的强调部分则为what引导的主语从句和something,而something后带有that引导的定语从句.

例5:Was it through the teacher __________ you came to realize the importance of learning English

A.who B.whom C.how D.that

[析]答案为D项.此题强调的是介词短语through the teacher,而不是名词teacher.故A,B项具有很强的迷惑性.

例6:It is the young man __________ looked for __________ caught the murderer.

A.that;who B.that;they C.they;that D.they;which

[析]答案为C项.本题考查了定语从句和强调句式.they looked for 前省略了关系代词that,that一方面引导定语从句,同时又在从句中做looked for的宾语,强调句为:It is the young man who/that caught the muderer.本句意思是"是那个他们在寻找的年轻人抓住了杀人犯".

例7:Was it seven o'clock __________ you finished your task

A.when B.that C.then D.which

[析]答案为A项.此题是含有when引导的时间状语从句,不是强调句型.

例8:She told us that it was a small mountain village __________ she lived with her grandparents.

A.that B.which C.where D.when

[析]答案为C项.此题中,where引导定语从句,同时又在从句中作状语.
