初中英语语法讲解：强调句结构详解

一、常考的强调句结构是 it 引导的句子。

It is (was) 被强调部分+ that (who) + 句子其他部分。

此结构强调的成分仅限于主语，宾语和状语。例如：

It was because of the heavy rain that he came late.

It was yesterday that Tom passed in the maths exam.

It was not until I had read your letter that I understood the matter.

原句：My father did the experiment in the lab yesterday evening.

强调主语：It was my father who did the experiment in the lab yesterday evening.

强调宾语：It was the experiment that my father did in the lab yesterday evening.

强调时间：It was yesterday evening that my father did the experiment in the lab. (注意不用when)

强调地点：It was in the lab that my father did the experiment yesterday evening.

二、强调句还有一种类型，就是用助动词do (did，does) 强调谓语。

She does like this horse. 她的确喜欢这匹马。

Please do take care of yourself. 千万保重。

三、注意事项：

1.被强调成分是主语，who/that之后的谓语动词应该在人称和数上与原句中的主语保持一致。

e.g. It is I who am right.

e.g. It is he who is wrong.

2.如果被强调的成分有同位语，同位语也应提前。

It was from him，his chemistry teacher，that Paul learned to watch carefully in class.

3. 被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格

It was he that helped me yesterday. It was me that he helped yesterday.

4. 被强调部分既包括人又包括物，用that不用who

lt was the things and people that they remembered that they were talking about.

5. 区分定语从句和强调句型某些定语从句和强调句型形式差不多，容易混淆。如果去掉it is/was ...that句子仍然通顺成立，则为强调句型，不成立不通顺，则为定语从句。

e.g. It was three years ago that he went to American for a further study去掉It was that句子为Three years ago he went to America for a further study.句子通顺，意思完整，那么，这就是一个强调句型。

典型例题

1. It was last night ___ I see the comet.

A.　the time　B.　when　 C.　that　　D.　which

答案C. 强调句的结构是：It +be +强调部分 + that (who) + 主谓句。　强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用 "who"，其余用that。

2. It is ten years ___ Miss Green returned to Canada.

A. that　B. when　 C. since　 D. as

答案C. 考点是连词用法。本题易误选为A. that. 其实本句不是强调句。
