“热巴不巴热”通过精心收集，向本站投稿了7篇高中英语强调句语法，下面是小编为大家推荐的高中英语强调句语法，欢迎大家分享。
篇1：高中英语强调句课件
基本结构：
It is (was)+被强调部分+ that (who)+句子其他部分。此结构强调的成分仅限于主语、宾语和状语。
例如：
It is not only blind men who make such stupid mistakes.
It was the goat’s eyes that he had seen in the darkness.
It is from the sun that we get light and heat.
It was not until I had read your letter that I understood the true state of affairs.
下面给出一个句子，根据强调的内容不同，做出的不同形式的强调句：
原句：My father did the experiment in the lab yesterday evening.
强调主语：It was my father who did the experiment in the lab yesterday evening.
强调宾语：It was the experiment that my father did in the lab yesterday evening.
强调地点：It was in the lab that my father did the experiment yesterday evening.
有几个方面是必须注意的：
1.条件，让步状语从句不能用强调句型改写，例如：
If it rains, we won’t go out. 如果下雨，我们就不出去。
We’ll try to finish the work in time though we are short of man power. 尽管我们人手不够，我们也会尽力按时完成工作。
2.It-type强调句可强调because引导的原因状语从句，但不可强调as, since引导的原因状语从句，例如：
I do it because I like it.因为我喜欢，我才干。可强调为：It is because I like it that I do it.
下面这个句子则不可以强调：
Since no one is against it, we’ll adopt the proposal.
3.It-type强调句可强调so that引起的目的状语从句，但不能强调so that 引起的结果状语从句，例如：
The six blind men asked the driver to stop the beast so that they could have a “look”. 六个盲人要求赶象人让这头巨兽停下来，以便他们能“看一看”。可强调为：It was so that they could have a “look” that the six blind men asked the driver to stop the beast.
下面这个句子则不可以强调：
He didn’t plan his time well, so that he didn’t finish the work in time.
4.对由until引起的短语或从句强调，要注意否定前移，例如：
I didn’t learn it until yesterday.写成强调句型是：It was not until yesterday that I learned it.
He didn’t come back until his wife fell asleep. 写成强调句型是：It was not until his wife fell asleep that he came back.
5.在中学英语课本中还多次出现“What…be…”结构的句型（简称wh-type强调句），它同样具有很浓的强调意味，例如：
What we need is more time.我们需要的是更多的时间。
我们可以用对待It-type强调句的方法，把“What…be…”作为一个框架而划去，所剩的也是一个完整的句子：We need more time.不同的是，what和be在句子中都可以担任成份。上面这个句子可以看成是 What引导一个主语从句，而be则 是系动词，后接表语。
（1）Wh-type强调句可用来强调主语、宾语、表语，例如：
But what surprised me most was to see some of the village people seated on the benches at the end of the room.
But what he was really interested in was beautiful paintings.
What I feel is hungry.
（2）wh-type强调句还可以通过使用动词不定式或动词-ing形式来强调句中的谓语动词或作宾语补足语的非谓语动词，例如：
What I did was (to) turn off the tap.
What I want you to do is (to) clean the room.
What I’m doing is teaching him a lesson.
（3）Wh-type强调句中的what从句，间或也作表语，例如：
This was what they had posted on the bulletin board then! This was what the black smith was reading! 原来贴在布告牌上的就是这么回事！铁匠在看的原来就是这个！
（4）Wh-type强调句的wh-从句，有时可能是以who, where或when引导，它们通常只用作表语，例如：
The headmaster was who I meant. 我指的就是校长。
Here is where the accident took place. 这儿就是事故发生的地方。
(On) Saturday is when the housewives are busiest. 星期六是家庭主妇们最忙的日子。

篇4：英语强调句常用句型？
英语当中的强调句，顾名思义，强调句的目的当然是为了强调我们用一个非常简单的句子来做强调句的变换的示范。I love you。我爱你。这个句子很简单，我们就记住变强调句的规则就是我要强调什么？就把这个内容往前放，然后呢在它一前一后加上 it is that。就可以了。我们看 I love you这个句子。
我要想强调I翻译成中文就是是我爱你。这就是强调句，我们把爱往前放，因为爱本来就在前面，所以很好办。在它左右两边加上。It is that。因为I又是一个人，我们仍旧可以说it is who，这个是没问题的。我们看一下 it is I that love you，it is I who love you？这就是强调句的第一种变化形式。
翻译成中文就是是我爱你。如果我想强调你呢？也就是我爱的是你，那同样规则，我们把you往前放，左右两边加上it is that。这就是 it is you that I love。注意到了吗？ it is you that I love。这里的I love仍旧是它原来的位置，这是强调句的`第二种情况。强调宾语。
好，我们再看，如果强调状语呢？比如说 I love you with all my life。我用我的生命永远爱着你。I love you with all my life。我想强调这个with all my life。同样我要把这个部分往前放，还是这个规则。It is with all my life that I love you。这就是强调状语。好，总结一下，强调句就是我要强调什么，我就把它往前放，然后前后加上。It is that就可以了。这里呢我想再提醒两点，第一点就是加it is that的时候呢，注意一下它的时态。有的时候会是 it was that。如果是过去，那就是it was。然后再加that，这是第一个我要提醒的。
第二个我要提醒的这种强调句的变换方式，唯独不能用来强调谓语动词。因为对于谓语动词的强调，它有另外一种强调的方式。比如说I love you。强调谓语动词就是我的的确确爱你。那英语是这么说的。I do love you。I do love you是强调一个do love。这个呢是加助动词，来强调谓语动词。I do love you。如果是过去呢就是 I did love you。这里呢我们需要注意。
篇5：语法复习五：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）

三、省略
为了使讲话和行文简洁，句中某些成分有时可省略。省略可分以下几种情况：
（一）简单句中的省略
1、省略主语：祈使句中主语通常省略。其它省略主语多限于少数现成的说法。
e.g. (I) Thank you for your help.（括号内为省略的词语，下同）
(I) see you tomorrow. (It) Doesn’t matter.
2、省略主谓语或主谓语的一部分。
e.g. (There is) No smoking. (Is there) Anything wrong? Why (do you) not say hello to him?
3、省略作宾语的不定式短语，只保留to。
e.g. ---- Are you going there? ---- I’d like to (go there).
He did not give me the chance, though he had promised to (give me the chance).
注意：如果该宾语是be动词或完成时态，则须在to之后加上be或have。
e.g. ---- Are you an engineer? ---- No, but I want to be.
---- He hasn’t finished the task yet. ---- Well, he ought to have.
4、省略表语。
e.g. ---- Are you thirsty? ---- Yes, I am (thirsty).
5、同时省略几个成分。
e.g. Let’s meet at the same place as (we met) yesterday.
---- Have you finished your work? ---- (I have) Not (finished my work) yet.
（二）并列句中的省略
两个并列分句中，后一个分句常省略与前一分句中相同的部分。
e.g. My father is a doctor and my mother (is) a nurse.
I study at college and my sister (studies) at high school.
（三）主从复合句中的省略
1、主句中有一些成分被省略。
e.g. (I’m) Sorry to hear that you are ill.
(It is a) Pity that he missed such a good chance.
2、省略了一个从句或从句的一部分，用so或not（切不可用it或that）代替。
e.g. ---- Is he coming back tonight? ---- I think so.
---- Is he feeling better today? ---- I’m afraid not.
这种用法常见的有：How so? Why so? Is that so? I hope so. He said so 及I suppose not. I believed not. I hope not等。（但I don’t think so比I think not更常用）。
（四）其它省略
1、连词that的省略：
①、宾语从句中常省略连词that，但也有不能省略的情况（参看“名词性从句”等有关部分）。
②、在定语从句中，that在从句中作宾语时可省略。
③、引导主语从句、同位语从句等的连词that一般不可省略。在表语从句中偶尔可省略。
2、不定式符号to的省略
①、并列的不定式可省去后面的to。
e.g. I told him to sit down and wait for a moment.
②、某些使役动词（如let, make, have）及感官动词（如see, watch, notice, hear, feel, look at和listen to等）后面作宾语补足的不定式一定要省去to，但在被动语态中须把to复原。
e.g. ---- I saw the boy fall from the tree. ---- The boy was seen to fall from the tree.
③、介词but前若有动词do，后面的不定式不带to。
e.g. The boy did nothing but play.
3、在某些状语从句中，从句的主语与主句主语一致时，可省去“主语 + be”部分。（参看“状语从句”有关部分）
4、连词if在部分虚拟条件句中可省略，但后面的语序有变化（参见“倒装句”有关部分）
5、主句与从句各有一些成分省略。
e.g. The sooner (you do it), the better (it will be).
四、插入语
英语句子中（尤其在口语中）常插入一些单词、短语或者句子，用来补充某些含义。语法上称他们为“插入语”。
（一）插入语的类型：
1、单词（多是副词），如：besides, however, otherwise, therefore, though等。
e.g. She is looking fit, though. 他看起来倒是健康。
I can, however, discuss this when I see you.
2、短语
e.g. China and India, for example, are neighbours.
By the way, where are you from?
3、句子
e.g. He is an honest man, I believe.
Jack, as far as I know, isn’t clever.
（二）插入语的位置
通常插入语位于句中，并用逗号隔开。但有时，也可位于句首或句末（见上面例句）。也有时，并不用逗号隔开。
e.g. You know that I think you are wrong. 我认为，你明白你错了。
What on earth do you mean? 你究竟是什么意思？
（三）插入语在句中的作用
一般来说，插入语在句中不起主要作用。如果把插入语抽去，句子的含义不大受影响。但是，有的插入语却是句子不可缺少的一部分。
e.g. He got the news from nobody knows where. 他这消息谁也不知道是从哪儿得来的。
（四）插入语的特殊用法
下面这种复杂的特殊疑问句，也可认为包含有“插入语”。这种疑问句（有的语法书也称为“混合疑问句”或“连锁疑问句”）常用来征询对方对某一疑问点的看法、判断、认识、猜度或请求对方重复一遍说过的话。口语中出现频率极高。常用动词有say, suppose, guess, believe, consider, think, imagine 等。
e.g. How long did you say she would stay here?
When do you suppose they’ll be back?
How old did you think she was
（五）大纲中要求掌握的常用作插入语的词语
by the way 顺便说，顺便问一下；so far 到目前为止；and so on 等等；on the contrary 相反； no wonder 不足为奇；as a matter of fact 事实上；come along 快点，来吧；in other words 换句话说；as usual 如同以往；as a result 因此，结果。

篇6：语法和词汇考点详解----倒装句、强调句、反意疑问句
【命题依据】高考试题每年都要涉及句法知识，这些特殊的句型结构，每年单项填空题都会出现1-2道。高考试题对这些句型结构的考查往往是以测试它们中的特殊结构为主，例如倒装句中否定副词位于句首；as引导让步状语从句的倒装；省略if的虚拟条件句等。又如强调句中的强调特殊疑问句以及强调句与其它相似句式的混合使用等。估计今后高考试题不会降低对这些特殊句型结构的考查力度。
[例题1] -Why can’t I smoke here?
-At no time ____ in the meeting room.
A. is smoking permitted B. smoking is permitted

篇7：语法复习五：强调句、It的用法、省略和插入语
语法复习五：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）
