强调句句型

1
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
eg. It was yesterday that he met Li Ping.
2、一般疑问句的强调句型：
Is/ Was it + 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
eg. 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？
eg. When and where was it that you were born
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.
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 … 。
谓语动词的强调

2
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。
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。

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
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。
强调句型考点

考点1
知识点：连接词
一般说来，如果被强调部分是人时，用连词that或who；被强调的部分是宾语，指人时也可以用whom；如果被强调部分是物，只能用连词that。
如：It was John and Mike who/that saw Mary in the street last night.
It is Mary whom/who he often helps.
It was in the street that I met him yesterday.
考点2
知识点：不同的强调成分
如：Mary met an old beggar in the street yesterday.
(强调主语) It was Mary who/that met an old beggar in the street yesterday.
(强调宾语) It was an old beggar whom/that Mary met in the street yesterday.
(强调时间状语) It was yesterday that Mary met an old beggar in the street.
(强调地点状语) It was in the street that Mary met an old beggar yesterday.
有时，be前可使用表示推测的情态动词。
如：It must be Peter who has let this secret out.
It might be last night that they did their homework.
考点3
知识点：时态
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...; 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...
如：It's Mary who/that meets an old beggar in the street.
It's Mary who/that is doing the housework.
It's Mary who/that has done such terrible things.
It's Mary who/that will have finished this task by the next week.
It's Mary who/that will be going to America.
It's Mary who/that will go to see the doctor tomorrow.
考点4
not...until 的强调句
强调含有not until的句子时，not 位于until从句前，主句谓语动词作相应变化，即it is(was)+not until从句+that +其它。
如：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.
It was not until he had finished the work that he went home.
It was not until 12 o’clock last night that my brother came home.
考点5
强调句的疑问句
强调一般疑问句中的某一成分时，要在主句中用一般疑问句的顺序。
如：Was it you that/who broke the window
Was it in the war that he lost his son
强调特殊疑问句中的疑问词，其结构模式是：“疑问词+ is/was + it +that...”。它同感叹句的强调模式极其相似，首先将疑问句开头的部分作为强调部分，套入强调结构，然后再将其变为疑问句。
如：Where were you born → Where was it that you were born
What did you want to see → What was it that y ou wanted to see
How many people are being trained for the important work →
How many people is it that are being trained for the important work
考点6
强调句型中的主谓一致
被强调的成分为原句的主语时，that/who之后的谓语动词应与被强调的名词或代词在人称和数方面保持一致关系，从而选用恰当的动词形式。
如：It is you who/that are wrong.
It is I who/that am answering the question.
注意1：但是如果被强调的部分是人称代词，按理应用人称代词主格形式，但在口语或非正式文体中也可以用其宾格形式，此时that/who的谓语动词要用单数第三人称形式is或was。
如：It is me/I who is being asked the favor.
注意2：在It is/was..., not...that...句型中，其谓语动词应与肯定部分的词保持一致关系。
如：It is my brother, not I that studies in that school.
It is you, not your sister that are in charge o f the company.
强调句型中的主谓一致
考点7
感叹句的强调结构
既要体现强调句型的形式特征，又要体现感叹句的自然语序。
如：How happy he looks! → How happy it is that he looks!
What a clever boy he is! → What a clever boy it is that he is!
“It is / was + 形容词 / 分词 / + that从句”是主语从句，若删去“It is / was...that...”，则原句不成立，It 为形式主语，真正主语为that后跟部分；而强调句型若删去“It is / was...that / who...”，原句结构与语意均完整，译成中文时，常可加上“正是……”“就是……”之类字眼。
1. 强调句与主语从句的区别
难点
It is true that he is honest.
It is known to all that China is a country with a long history.
It was here that he fell off his bicycle.
识别下列从句，并比较其中文意思
It is true that he is honest. (主语从句)
It is known to all that China is a country with a long history. (主语从句)
It was here that he fell off his bicycle.(强调句)
试比较：
在被强调的名词后再设计一个以该名词为先行词的定语从句，这时不要把定语从句当作强调句。
It was this school where (in which) he once studied that gave him a chance of teaching.
2. 含有定语从句的强调句型
3. 强调句型与状语从句的区别
试比较：
It was at 7:00 that I arrived.
It was 7:00 when I arrived.
It was two years ago that I began to learn drawing
It is(has been) two years since I began to learn drawing
It was two years before they came to see us.
It was two years later that they came to see us.
It won’t be long before we graduate from the school.
It will be two years before we graduate from this university.
试比较：
It was at 7:00 that I arrived. (强调句型，强调时间状语at 7:00)
正是在7:00时，我到了。
It was 7:00 when I arrived. (时间状语从句，在7:00前无介词at)
当我到达时， 时间是7:00。
It was two years ago that I began to learn drawing.(强调句型，前后时态一致) 正是在两年前我开始学习绘画。
It is(has been) two years since I began to learn drawing. (since引导的时间状语从句，前后时态不一致) 自从我学习绘画以来已经有两年了。
It was two years before they came to see us. (时间状语从句) 过了两年后他们才来看我们。
It was two years later that they came to see us.(强调句型) 正是两年后他们才来看我们的。
It won’t be long before we graduate from the school. (时间状语从句) 不久我就将毕业了。
It will be two years before we graduate from this university. (时间状语从句) 再过两年我们就将大学毕业了。
试用强调句表达“我觉得物理太难了”
