英语强调句do的用法
强调句型的构成是：It is (was) + 被强调部分+ that (who) + 句子的其他成分。被强调的部分放在 It is (was) 之后，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，可以由who代替that。
1. 被强调的成分举例：
原句：Tom found my pen in the classroom yesterday.
强调主语：It was Tom who / that found my pen in the classroom yesterday.
强调宾语：It was my pen that Tom found in the classroom yesterday.
强调地点状语：It was in the classroom that Tom found my pen yesterday.
强调时间状语：It was yesterday that Tom found my pen in the classroom.
2. 强调句型的一般疑问式：
直接把is或was提到it之前即可。例如：
Was it Tom that found your pen in the classroom yesterday?
3. 强调句型的特殊疑问式：
特殊疑问词+ is (was) it + that +句子的其他成分。特殊疑问词即是被强调的成分。例如：
Who was it that found your pen in the classroom yesterday?
4. that (who) 有时可以省略：
这种强调句型中的that或who有时可以省略。例如：
It was my brother (that / whom) you saw the other day.
5. 强调原因状语从句要注意：
若从句由as或since引导，强调时则改为because，这是因为，because引导的原因从句表示的意义非常强烈，符合强调句的目的。例如：
As she got up late, she missed the first bus. 变为：
It was because she got up late that she missed the bus.
6. 强调句的否定转移：
有些否定句在变成强调句时，要把否定转移到被强调的词语之前。尤其是“not... until...”句式的强调要特别注意。例如：
He didn't realize his mistake until the teacher had told him. 变为：
It wasn't until the teacher had told him that he realized his mistake.
【注意】 在强调句式中，虽然not被提前，但“not... until...”句型不要倒装。
高考中强调句型考查热点
考点一：强调句型的基本结构
强调句型“It is / was + 被强调的成份 + that + 其他成份”用来强调主语、宾语和状语等成份。that只起连接作用，不作成份，但不能省略。有时强调的部分比较特殊，如主语从句、状语从句、名词、不定式短语、V-ing的复合结构等。如：
It was in the library that I saw her yesterday. 我昨天正是在图书馆见到她的。
考点二：特殊句式中的强调句型
1. 如果强调的是特殊疑问句中的疑问词，表示“到底”、“究竟”等语气时，就用如下结构：
“特殊疑问词 + is / was + it + that + 该句的其余部分”。如：
How is it that you usually go to work? 你通常是怎样去上班的？
2. 在强调“not... until”结构中由until所引导的短语（或从句）作时间状语时，要用固定的强调句型：“It + is / was + not until... + that + 该句的其余部分”，that所引导的从句中的谓语动词用肯定式。如：
His father didn't come back from work until 12
o'clock. = It was not until 12 o'clock that his father came home form work. 直到12点他的爸爸才下班回家。
考点三：强调句型与时间状语从句、定语从句的判断
强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别。试比较：
It was on March 1 that I had my hair cut. (强调句)
It was March 1 when I had my hair cut. (后面是定语从句)
判断是否是强调句，可采用“还原法”。如果还原为一般句式后，句子各种成份完整，则是强调句。否则不是。如第一句可还原成：I had my hair cut on March 1.
考点四：偶尔考查谓语动词的强调句式
英语中常用助动词do、does或did强调谓语。如：
He did go to the airport yesterday, but he didn't find you. 他昨天确实去了机场，但他没有找到你
我们中国人不吃这一套
We Chinese don't eat this set.
强调句，是基本语法 ，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。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)..."。
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.
⒉、adv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.
⒋、what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.
6、比较状语从句可表强调：
Nothing is more imperative than to learn from the past.
7、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.
