强调句（奥赛数据库）
一、强调句型
为了强调句子的某一成分（通常是主语、宾语、或状语），常用强调句型：
It is (was) +被强调部分+that(who)…° 表示强调的 it 在句子中作主句的主语；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，that 和 who 都
可用。如： Last night I saw a film in the Youth Palace.
强调主语：It was I that (or: who) saw a film in the Youth Palace last night.
强调宾语：It was a film that I saw in the Youth Palace last night.
强调地点状语：It was in the Youth Palace that I saw a film last night.
强调时间状语：It was last night that I saw a film in the Youth Palace.
二、强调句的连接词
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。
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.
三、强调句的时态
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...。
Mary met an old beggar in the street yesterday.
It was Mary who/that met an old beggar in the street yesterday. (强调主语)
It was an old beggar whom/that Mary met in the street yesterday. (强调宾
语) It was yesterday that Mary met an old beggar in the street. (强调时间状
语)
It was in the street that Mary met an old beggar yesterday. (强调地点状语)
有时，be 前可使用表示推测的情态动词。
It must be Peter who has let this secret out.
It might be last night that they did their homework.
四、 强调含有 not until 的句子。
在强调 not until 句型时，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。
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.
五、强调句的疑问句
强调结构的疑问形式：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。例如：
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。
1. Where were you born? → Where was it that you were born?
2. What did you want to see? → What was it that you wanted to see?
3. How many people are being trained for the special work?
→ How many people is it that are being trained for the special work ?。
六、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。
It is you who/that are wrong.
It is I who/that am answering the question.
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。
It is me who is being asked the favor.
另外在 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。例如： It is my brother, not I that studies in that school.
It is you, not your sister that are in charge of the company.
六、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。
1. How happy he looks! → How happy it is that he looks!
2. What a clever boy he is! → What a clever boy it is that he is!
七、强调句型的鉴别方法及相似句型的辨析
强调句型极易与定语从句、名词性从句、状语从句等相关句型混淆，判断的方法
是：强调句型中去掉 It is/was…that 剩下的部分在语法和意义上仍然是一个完整
的句子。
It was yesterday that I met him. 去掉句中的 It was
Yesterday I met him. 句意和语法都非常正确，说明这是一个强调句。而其他句
型则不行。
