强调句,是基本语法,它是一种修辞,是人们为了表达自己的意愿或情感而使用的一种形式。强调句可以有多种表现形式,英语常用的强调结构是"It is (was)+被强调部分(主语、宾语或状语)+who (that)..."。下面请结合例句来看一下这一结构。

it强调主语的情况

被强调的主语是人时,可用It is/was ... That/who ...,但如果被强调的部分既包括人又包括物,只能用that。

He bought a book yesterday.

It was he that /who bought a book yesterday.

是他昨天买了一本书。

The famous writer and his works have aroused great interest among the students.

It is the famous writer and his works that have aroused great interest among the students.

在学生中引起极大的兴趣的正是这位著名作家以及他的作品。

it强调宾语的情况

They often talk about the movies and stars.

It is the movies and stars that they often talk about.

他们经常谈论的是电影和明星。

it强调状语的情况

英语中的状语种类很多,一般都可以用It is/was ... that ...来强调。

He let out the secret after the guest had gone away.

It was after the guest had gone away that he let out the secret. 是在客人走后,他才说出了秘密。

it强调宾语补足语的情况

We painted the wall white.

It was white that we painted the wall.

我们把墙漆成的是白色。

"It is (was)+被强调部分(主语、宾语或状语)+who (that)..."这一结构非常灵活,除谓语部分外几乎都能强调。需要强调谓语部分时,只需要在谓语之前根据人称和时态加上do/did/does即可。强调句是高频考点,请大家认真记忆。
