句型11

It强调句型

强调句的基本构成:It is/was + 被强调的部分 + who(主要指人时)/that + 其余部分

[注意1]

这种结构可以强调句子的主语、宾语、状语(包括时间,地点,方式,原因等),但是不能强调谓语动词(参考句型15)。

原句的谓语动词如果是现在或将来时态,用It is…that/who….;

原句的谓语动词如果是过去时态,用It was…that/who….;

强调时间、地点、原因或方式时不要用when, where或how, 必须用that。

[例句1]

I saw him in the street yesterday afternoon.

→It was I who saw him in the street yesterday afternoon.(强调主语)

→It was in the street that I saw him yesterday afternoon.(强调地点状语)

→It was yesterday afternoon that I saw him in the street.(强调时间状语)

→It was him that/who I saw in the street yesterday afternoon.(强调宾语)

[例句2]

He didn't go to bed until his mother came back.

→It was not until his mother came back that he went to bed.

He didn't do his homework until his father came back from work.

→It wasn't until his father came back from work that he did his homework.

[例句3]

Only when you nearly lose someone do you fully realize how much you value him.

→It is only when you nearly lose someone that you fully realize how much you value him.

只有你快要失去某个人时,你才意识到你是多么尊重他。

[例句4]

I was late again because the traffic was very heavy during the rush hour.

→It was because the traffic was very heavy during the rush hour that I was late again.

(强调句中只能强调由because引导的原因状语从句,because不能换成since, as, for, now that等)

[注意2]强调句的疑问结构

一般疑问句 Is / Was it +被强调部分 +who / that …?

特殊疑问句 特殊疑问词+is /was +it +who / that…?

What is/was it that…? Who is/was it that…? When is/was it that…?

Where is/was it that…? Why is/was it that…? How is/was it that…?

[例句1]

I saw him in the street yesterday afternoon.

→When was it that you saw him in the street?

→Who was it that you saw in the street yesterday afternoon?

→Where was it that you saw him yesterday afternoon?

[例句2]

I don't know when he will come back.

→I don't know when it is that he will come back.(宾语从句疑问词后用陈述句语序)

-How was it that you got in touch with Mr. Smith? 你是怎么和Smith先生联系上的?

-Trough a friend of mine. 通过一个朋友。

句型12
