英语强调句型的用法分析及讲解

　　一、英语强调句型的用法

　　
在英语中，咱们常用It is／was… who/that结构来突出强调句子的某一成分(个别是句子中主语，宾语或状语)。在这个句型中，it不词汇意思，只是引出被强调的成分。假如被强调的成分是表示人的词，用who或that来连接都可能。如果是其它成分，则一律用that来衔接。

E.g. It is my mother who／that cooks every day.

E.g. It was yesterday that Tom passed in the maths exam．

　　二、利用本英语强调句型的几个留心事项

　　
1．被强调成分是主语，who／that之后的谓语动词应该在人称跟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．

e.g. It is the students who are lovely．

2．即使被强调成分是句子中的时间状语，地点状语，起因状语等，也不能用when，where, because，免费学习英语的网站，要用 that。

E.g.  It was after the war was over that Einstein was able to come back to his research work again .

E.g. It was in front of the bank that the old lady was robbed．

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

　　3．英语强调句型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．

　　4．英语强调句型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.

5．被强调部分既包含人又包括物，用that不用who

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

　　三、分辨定语从句和英语强调句型 某些定语从句跟强调句型形式差不久，容易混淆。如果去掉it is／ was ...that句子仍然通顺成破，则为强调句型，不成破不通顺，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。
