It強調(diào)句型

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

(1)這種結(jié)構(gòu)可以強調(diào)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(diào)謂語動詞。

原句的謂語動詞如果是現(xiàn)在或?qū)頃r態(tài)，用It is...that/who...。

原句的謂語動詞如果是過去時態(tài)，用It was...that/who...。

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

一般疑問句：Is/Was it＋被強調(diào)部分＋who/that...?
