It強調句型

強調句的基本構成：It is/was + 被強調的部分 + who(主要指人時)/that + 其余部分

[注意1]

這種結構可以強調句子的主語、賓語、狀語(包括時間，地點，方式，原因等)，但是不能強調謂語動詞(參考句型15)。

原句的謂語動詞如果是現在或將來時態，用It is…that/who….;

原句的謂語動詞如果是過去時態，用It was…that/who….;

強調時間、地點、原因或方式時不要用when, where或how, 必須用that。

[例句1]

I saw him in the street yesterday afternoon.

→It was I who saw him in the street yesterday afternoon.(強調主語)

→It was in the street that I saw him yesterday afternoon.(強調地點狀語)

→It was yesterday afternoon that I saw him in the street.(強調時間狀語)

→It was him that/who I saw in the street yesterday afternoon.(強調賓語)

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

[例句3]

[例句4]

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

(強調句中只能強調由because引導的原因狀語從句，because不能換成since, as, for, now that等)

[注意2]強調句的疑問結構

特殊疑問句 特殊疑問詞+is /was +it +who / that…?

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