It iswas……that......强调句用法

It is/was……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.(强调地点状语)

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) …+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.“not…until…”句型的强调结构为“It is not until…that…”应注意把否定词not转移到until前面。如：I didn't go home until rain stopped.(直到雨停了我才回家)。

强调句为：It was not until rain stopped that I went home.

I didn't know the news until yesterday.(直到昨天我才知道那个消息)

强调句为：It was not until yesterday that I knew the news.

考点辨析练习

一、考查对强调句型结构的识别

强调句型的基本结构形式为:It is/was+被强调部分

+that/who/whom (高中阶段不要掌握)+句子的其余部分。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...。例如:

1. It is the ability to do the job________matters not where yo u come from or what you are.

A. one

B. that

C. what

D. it

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...。例如:

2. It was between 1989 and 1999_____ great changes took p lace in our hometown.

A. when

B. that

C. which

D. because

有时,be前可使用表示推测的情态动词构成复合结构。（高中不要求掌握）例如:

It must be Peter who has let this secret out.一定是彼得将这个秘密泄露出去的。

It might be last night that they did their homework.他们也许是昨晚做完作业的。

Key: 1. B 2. B

二、考查强调句型的疑问句式

变换句型是增加试题难度的手段之一,强调句型结构本身就让学生"有些糊涂",若再使用其疑问式就更有些让学生"头疼"了。但只要同学们从一开始学习时,就掌握得扎实、牢固,这些"纸老虎"就能一个个被你击溃!

一般疑问句式:Is/Was it+被强调部分+that/who+句子的其余部分? 特殊疑问句式:特殊疑问词+is/was it+被强调部分+that/who+句子的其余部分?

3. Was________his illness________he didn't go to see the fil m?

A. necessary; when

B. that important of; why

C. even if; for

D. it because of; that

E. it although; then

4. Was________that I saw last night at the corner?

A. it you

B. not you

C. you

D. that yourself

Key: 3. D 4. A

三、考查强调句型的易错点

强调句型的学习、掌握中有很多难点,同时也是易错点,这些学生容易出错的地方,也是各种考试考查的重点和热点。这些易错点有:

1)强调时间、地点、原因状语时,通常只使用that,而不能使用when,where,why。

5. It was only when I reread his poems recently________I beg an to appreciate their beauty.

A. until

B. that

C. when

D. so

6. It was in Qingdao________I saw the sea for the first time.

A. what

B. that

C. when

D. which

7. It was because of bad weather________the football match had to be put off.

A. so

B. so that

C. why

D. that

以上三题均为强调句型,分别强调时间状语

(only when I reread his poems recently)、地点状语(in Qingdao)和原因状语(because of bad weather),均只能使用that。

2)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。

8. It was not until 1920________regular radio broadcast bega n.

A. while

B. which

C. that

D. since

Key: C

3)强调主语时,谓语动词应与之保持一致。

【误】 It is I who/ that is going to be sent there to help them. 【正】 It is I who/ that am going to be sent there to help them.

4) 强调主语或宾语且其为人称代词时,应注意其形式仍用主格或宾格形式。

【误】It was her who/that told me about it.

【正】It was she who/that told me about it.

【误】It is I who/that the teacher has punished.

【正】It is me who/that the teacher has punished.

四、考查强调句型与相关句型的辨析

强调句型极易与定语从句、名词性从句、状语从句等相关句型混淆,故高考也常考查这方面的内容。例如:

A. 与定语从句的辨析

9. Was it during the Second World War__he died?

A. that

B. while

C. in which

D. then

B.与名词性从句的辨析

10. It was________he said________ disappointed me.

A. what; that

B. that; that

C. what; what

D. that; what

C. 与状语从句的辨析

11. It was about 600 years ago ____

the first clock with a face and an hour hand was made.

A. that

B. until

C. before

D. when

D. 与there be句型的辨析

12. is no possibility________Bob can win the first prize in th

e match.

A. There; that

B. It; that

C. There; whether

D. It; whether A 答案与简析:

9. A。本题易错选C,以为是定语从句修饰

the Second World War。

10. A。本题同时考查强调句型和名词性从句这两个知识点,学生易错选C,认为两处均为名词性从句。

11. A。本题易错选C和D,认为是时间状语从句或定语从句。判断是否强调句型的一个简易方法是"还原法",即看其能否删除

"It is/was...(that/who/whom)..."部分后还原为一个单句。能者则是,不能者则不是。如上述9-11题分别可还原为:

He died during the Second World War.

What he said disappointed me.

The first clock with a face and an hour hand was made about 600 years ago.

12. A。本题为there be句型,而非强调句型。that引导的为同位语从句,作possibility的同位语。

倍数表达法

倍数表达法 是历届高考的热点。当我们要表达甲是乙的几倍时，通常可使用以下句型： 1.倍数+as+形容词或副词的原级+as+其它。这种结构又常演变成下列两类： ①倍数+as+many+可数名词复数+as;②倍数+as+much+不可数名词+as。如： There are seven times as many people as I expected.是我预料的人数的七倍。 There is five times as much coffee in this glass as in that one.这个杯子里的咖啡是那个杯子里的五倍。 2.倍数+形容词（或副词）的比较级+ than+其它。如： The hall is five times bigger than our classroom.这个大厅的面积比我们教师大五倍。 3.倍数+the size/height/length/width.etc.+of+其它。如： This road is six times the length of that one.这条路是那条路的六倍长。 4.计量名词+of+名词+be+倍数+that+of+其它。如： The size of the newly broadened square is four times that of the previous one.新扩建的广场为以前的四倍大。 5.倍数+what从句。如： The production is now three times what it was ten years ago.现在的产量是十年前的三倍。 6.倍数+more+名词+than+其它。如： There are nine times more books in his bag than in yours. 他书包里的书比你书包里的书多九倍。 7.其它表达。如：

语法中that的用法

“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下： 第一、that 用作形容词（后接复数名词时用those）。 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时） He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough. ②引导主语从句。通常采用it作形式主语的句型。 That the earth goes around the sun is known to everyone. （It is known to everyone that the earth goes around the sun.） ③引导表语从句。 The trouble is that we are short of money. ④引导同位语从句。 引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明： The news that he resigned from office surprised us. The idea that he holds is very common nowadays on campus. 2. that引导状语从句①引导目的状语从句。 Bring it nearer that I may see it better. ②引导结果状语从句。What have I done that he should be so angry with me? ③引导原因状语从句。 I am afraid that I will fail in the driving test. ④引导让步状语从句。意为“虽然、尽管”。

英语倍数表达法基本句型

一. 表达倍数的三个基本句型 1.“A+be动词/谓语动词+倍数+as+形容词/副词原级+as+B”，表示“A正好是B 的多少倍”。例如： Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。 This big stone is three times as heavy as that one. 这块大石头的重量是那块的三倍。 The plane flew ten times as high as the kite. 那架飞机的飞行高度是那只风筝的十倍。 2. “A+be动词/谓语动词+倍数+形容词/副词比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。例如： This rope is twice longer than that one. 这根绳子比那根绳子长两倍（是那根绳子三倍长）。 This hall is five times bigger than our classroom. 这个大厅比我们的教室大五倍(是我们教室的六倍大)。 The car runs twice faster than that truck. 这辆小车的速度比那辆卡车快两倍（是那辆卡车的三倍快）。 3. “A+be动词+倍数+the size/height/length/width, etc+of+B”，表示“A正好是B的多少倍”。例如： This street is four times the length of that one.这条街是那条街的四倍长。 This hill is four times the height of that small one.这座山的高度是那座小山的四倍。除表达倍数的三个基本句型外，我们还要掌握其基本句型的7种变形。

China is no longer the country that she was. 6.如有两个定语从句,其中一个已用which引导,另一个宜用that . Edison built up a factory which produced things that had never been seen before. 7.在there be句型中,只用that. He asked for the latest book (that) there is on the subject. 8.当先行词被the very, the last, the next, the only，the same 等词修饰时。 e.g. This is the very book that I lost yesterday. 9.当先行词又有人又有物时。 e.g. I won’t forget the things and the persons that I saw. 10. 先行词被all, every, no, any, little, some, much等修饰时。 I’ve read all the books that are not mine. 只能使用which的情况。 1、非限制性定语从句(即通常用逗号与主句隔开，如果去掉逗号，整个句子仍能表达完整的意义的定语从句)中。 e.g. Mary has a book, which is very precious. 2、在介词之后。 e.g. This is a house in which lives an old man. 3、当主句中的主语被that修饰时。 e.g. That dog which I found in the street belongs to Mary. 4. 非限定性定语从句修饰的是前面的整个句子，而且关系代词和关系副词前面有逗号, 用which开始的定语从句修饰前面半句 e.g. He will wear no clothes, which will distinguish（区分，辨别）him from his fellow men.

考研语法小知识：that从句用法

that 用法

That 用法总结 第一、that 用作形容词（后接复数名词时用those）。 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。 That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时） He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。 The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。 I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough. ②引导主语从句。通常采用it作形式主语的句型。 That the earth goes around the sun is known to everyone. （It is known to everyone that the earth goes around the sun.） ③引导表语从句。 The trouble is that we are short of money. ④引导同位语从句。 引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明： The news that he resigned from office surprised us. The idea that he holds is very common nowadays on campus. 2. that引导状语从句 ①引导目的状语从句。 Bring it nearer that I may see it better. ②引导结果状语从句。 What have I done that he should be so angry with me?
