I. 句式讲解

1. 强调句型的基本结构形式

It is/was + 被强调部分+ that + 句子的其余部分

当被强调部分是人时that也可以换成who

原句:Professor Liu teaches us English this year.

强调主语:It is Professor Liu who teaches us English this year.

强调宾语:It is English that Professor Liu teaches us this year.

强调状语:It is this year that Professor Liu teaches us English.

2. 强调句型的特点

去掉It is (was) that (who) 后,在不添词、不减词后,剩下的部分能组成一个完整的句子。这也是判断一个句子是否是强调句型的依据。

3. 强调句型的时态

如果原句中谓语动词使用的是现在或将来时间范畴的时态(一般现在时、现在进行时、现在完成/现在完成进行时、一般将来时、将来进行时、将来完成时等),用___________________

如果原句中谓语动词为过去时间范畴的时态(一般过去时、过去进行时、过去完成时、过去将来时等),则用___________________

4. 强调句型的一般疑问句式

Is/Was it + 被强调部分+that+句子的其余部分。

_____________________________________. 是刘教授今年教我们英语吗?(强调句)

5. 强调句型的特殊疑问句式

特殊疑问句+is/was it+被强调部分+that+句子的其余部分。

_____________________________________. 今年教我们英语的是谁?

_____________________________________. 刘教授今年是教我们什么的?

6. not…until句型的强调句型

当被强调的是not…until句型时,应将not置于until之前,主句由否定句改为肯定句。

如:He didn’t leave until 11 o ’clock.他直到11点才离开。

_____________________________________.(强调not until时间状语)
