特殊句式（強(qiáng)調(diào)、倒裝、省略及其他）考點 強(qiáng)調(diào)和強(qiáng)調(diào)句型

考點3 強(qiáng)調(diào)和強(qiáng)調(diào)句型

1. 助動詞do表示強(qiáng)調(diào)

謂語動詞前用do的形式加強(qiáng)語氣，相當(dāng)于“務(wù)必，千萬，一定；確定”等。它通常只能強(qiáng)調(diào)一般現(xiàn)在時和一般過去時。

He does look well. 他確實看上去很健康。

You did give me a fright. 你可真是嚇了我一跳。

Do be careful in making such experiment. 做這樣的實驗千萬要小心。

2. 強(qiáng)調(diào)句型

強(qiáng)調(diào)句型為：It is（was）+除謂語以外的被強(qiáng)調(diào)部分+that/who+句子其他部分。

構(gòu)成強(qiáng)調(diào)句的it本身沒有詞義；強(qiáng)調(diào)句中的連接詞一般只用that，強(qiáng)調(diào)的主語如果是人，可以由who代替that。即使在強(qiáng)調(diào)時間狀語和地點狀語時that或who也不可省略。強(qiáng)調(diào)句中的時態(tài)一般只有兩種，一般現(xiàn)在時和一般過去時，原句謂語動詞是一般過去時、過去完成時和過去進(jìn)行時，用It was...，其余的時態(tài)用It is...。

強(qiáng)調(diào)主語：It was Tom who/that found my pen in the classroom yesterday.

昨天是湯姆在教室里找到了我的筆。

強(qiáng)調(diào)賓語：It was my pen that Tom found in the classroom yesterday.

昨天湯姆在教室里找到的是我的筆。

強(qiáng)調(diào)地點狀語：It was in the classroom that Tom found my pen yesterday.

昨天湯姆是在教室里找到我的筆的。

強(qiáng)調(diào)時間狀語：It was yesterday that Tom found my pen in the classroom.

湯姆是昨天在教室里找到我的筆的。

注意

在某些情況下，強(qiáng)調(diào)句型中的It is（was）的be動詞也可以有其他形式，比如：

It may have been... that/who... 或許是……

一般去掉It was that句子仍然成立，且句意通順，則為強(qiáng)調(diào)句型，不成立不通順，則為其他形式。

It is well known that Sherlock Holmes was a famous detective.（主語從句）

眾所周知，夏洛克·福爾摩斯是一位著名的偵探。

It was three years that I spent in American for a further study.（定語從句）

我在美國深造了三年的時間。

It was on February 12, 1809 that Lincoln was born.（強(qiáng)調(diào)句型）

林肯是在1809年2月12日出生的。

It was three years ago that he went to American for a further study.（強(qiáng)調(diào)句型）

他是三年前去美國深造的。

3. 強(qiáng)調(diào)句型的疑問句式

（1）一般疑問式：直接把is或was提到it之前即可。

Was it Tom that found your pen in the classroom yesterday?

昨天是湯姆在教室里找到了你的筆嗎？

（2）強(qiáng)調(diào)句型的特殊疑問式：“特殊疑問詞+is/was+it+that+該句的其余部分”。

How is it that you usually go to work? 你通常是怎樣去上班的?

4. 強(qiáng)調(diào)句型與not... until...句型連用

在強(qiáng)調(diào)not... until...結(jié)構(gòu)中由until所引導(dǎo)的短語（或從句）作時間狀語時，要用固定的強(qiáng)調(diào)句型：“It+is/was+not until...+that+其他”，that所引導(dǎo)的從句中的謂語動詞用肯定式。

His father didn’t come back from work until 12 o’clock.

→It was not until 12 o’clock that his father came back form work.

直到12點他的爸爸才下班回家。

5. 強(qiáng)調(diào)句型與原因狀語從句連用

若從句由as或since引導(dǎo)，強(qiáng)調(diào)時則改為because，這是因為because引導(dǎo)的原因從句表示的意義非常強(qiáng)烈，符合強(qiáng)調(diào)句的目的。

Since he joined the army, he had to give up his career as an actor.

→It was because he joined the army that he had to give up his career as an actor.

正是因為他參了軍，所以他不得不放棄了作為演員的事業(yè)。
