强调句

教学目标：Enable students to master the basic structures of emphatic pattern. 教学重难点：Enable students to master the special structures of emphatic pattern. 教学设计：

I. 考点分析

1. 特殊句式主要指：省略、倒装、强调、祈使、反意疑问句等。其中高考考查的重点是祈使、倒装和强调结构。

2. 强调句型

(1)强调句型的几种构成形式。

(2) not until…的强调。

(3)

not… but….的强调

(4)强调句型和其他带有it的复合句型的区别。如：强调句型与主语从句、定语从句、时间状语从句的区别。

II. 教学过程

1. 对谓语动词的强调

强调谓语动词时，用“do/does/did＋动词原形”来表示，意为“确实，一定，肯定”,

do还可以用于祈使句。

e.g. Do be careful when crossing the street. The train does move. They did come to see you yesterday，but failed to meet you. 2. It强调句型

1) It强调句型的基本形式

It强调句型最基本的句式结构为：It be＋被强调部分＋that/who＋句子；

被强调部分是除谓语之外的其他句子成分，可以是单词、短语，也可以是从句；当强调人时，可以用who 或that；强调其他成分，则只能用that。

It is I who/that am right. (强调主语) 2) 对not...until...结构的强调

句型为：It is/ was not until + 被强调部分

+ that + 其他部分

。

I didn't realize she was a famous film star until/till she took off her dark glasses.

→It was not until she took off her dark glasses that I realized she was a famous film star. 注意

：强调句只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not ... 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。

It was not until he went abroad that he knew the importance of family for him.

3. 强调句的一般疑问句和特殊疑问句

1) 强调句的一般疑问句的基本句型为：

Be＋it＋被强调部分＋that/who＋句子其他成分

Is it Professor Wang who teaches you English? 2) 强调句的特殊疑问句的基本句型为：

特殊疑问词＋be＋it＋that/who/whom＋句子其他成分

What is it that you want me to do?

注意

：强调句的特殊疑问句用于名词性从句中，要用陈述语序。

I have no idea when it was that I lost my wallet. 4. 强调句型应注意的问题

(1) 谓语动词人称和数的一致性。

在强调句中，如果强调的是句子的主语，其后谓语动词应和被强调部分的人称和数保持一致。

It is Mary and Tom who often do good deeds. (2) 强调时间、地点、原因、方式状语时，一律用that，不用when，where，why，how。

It was because he was ill that he was absent.

他缺席是因为他病了。
