强调句
1、 什么是强调句
是一种修饰，是人们为了表达自己的意愿或情感而使用的一种形式
2、 如何强调
①语音手段
通过语句重音
②词汇手段
用形容词、副词、否定词等
③语法手段
用强调词（助动词）或强调句式
一、 强调词
用助动词强调动词，结构：
Do/does/did + 动词原形
I do love you.
He does love you.
He did send you a letter last week
注意：
强调词只能强调动词（谓语动词），
只能强调现在时和过去时，不能强调将来时。
二、 强调句
1、 基本结构：
“it is/was +被强调部分+that/who+句子剩余部分”
动词的数和时态均和被强调部分无关。
被强调部分只和连接词有关。
It was I that/ who met my teacher in the street yesterday.
技巧：（如何判断是不是强调句）
去掉it，was/is, that/who三部分，剩余部分仍然能组成一句完整的话。
It you that/who I love.
It is I that/who love you
注意：
①只有is/was两种形式，和句中时态保持一致。
②都可用that，当被强调部分是人时，还可以用who。
③没有will be 这种时态，用is即可
④不强调动词（谓），可强调其它成分。
例：he met an old friend in the street yesterday.
强调主语：
It was he that/who met an …
强调宾语：
It was an old friend that/who he met in the street yesterday
强调地点状语：
It was in the street that he met an old friend yesterday.
强调时间状语：
It was yesterday that…
强调谓语：
He did meet an …
2、 一般疑问强调句
基本结构：
“was/is +it +被强调部分+that/who+剩余?”
强调主语：
Was it he that/who met an …？
强调宾语：
Was it an old friend that/who he met in the street yesterday？
强调地点状语：
Was it in the street that he met an old friend yesterday？
强调时间状语：
Was it yesterday that…？
强调谓语：
He did meet an …
3、 特殊疑问强调句
基本结构：
“特殊疑问句+was/is+ it + that/who+剩余”
强调主语：
Was it who that/who met an …？
强调宾语：
Was it who that/who he met in the street yesterday？
强调地点状语：
Was it where that he met an old friend yesterday？
强调时间状语：
Was it when that…？
4、 一个句型
“it was not until +时间+that …”
It was not until now that I know your name.
It was not until yesterday that I heard form him.
辨析：强调句中的it和形式主语it的区别
①it做形式主语
It is +n+ that …
It is +adj + that…
…+adj+ to do
It is +过去分词+that
It + 不及物动词+that…
It is +adj+ for sb to do sth
It is +adj +of ab to do sth
②强调句中的it和形式主语it的区别
方法：按照是不是强调句的方法来判度，
