▲高考英语语法必考知识点：强调句
强调句(The Emphatic Pattern)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。
▲高考英语语法必考知识点：强调句的常用句型
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。
▲高考英语语法必考知识点：强调句的形式
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.
▲高考英语语法必考知识点：强调句的结构
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）
