not代替。常用于此类的动词有believe, think,

expect, guess, hope, imagine, suppose, say, tell

等以及appear, seem, afraid etc. ）

–She must be busy now?  --If so, she can’t go with us.

–Is she feeling better today? --I’m afraid not.

Do you think he will attend the meeting?

 --I guess not.

-Are you happy today?

-I hope so

-Are you unhappy today?

-I hope not .

【四】含有动词不定式回答省略简化

(1)只保留动词不定式的符号“to”

为了避免重复，有时候不定式中的主要动词可以省略。只剩下不定式的符号“to”常保留“to”的动词结构有expect to , love to , like to ,prefer to ,used to , be going to , mean to , ought to , try to , plan to , be happy to , be glad to , be eager to , be willing to , be ready to

-Would you like to come with us?

-Yes, I’d love to

-Do you live here?

-No, but I used to

-Would you look after my cat while I am away?

-I’ll be happy to

-Will you go together with me

-Yes, I will be glad to.

-You can go with us if you want to.

You don’t know her? But you ought to

(备注：如果不定式是动词be， 或者have 表示有，be 和have 不能省略，

-Is your father a reporter?

-No, but he used to be.

-I didn’t tell him the news

-Oh, you ought to have

Mary is not what she used to be.

【五】状语从句（主语+谓语）省略简化

(在某些状语从句中, 从句的主语与主句的主语一致时, 可省去“主语+be”部分)

原句子：When he was  still a boy of 10, he had to work day and night.

简化后的句子：

(1)When still a boy of 10, he had to work day and night.

(2) as a boy of 10, he had to work day and night

原句子：While you are cycling, don’t forget the traffic lights. 

简化后的句子：

While cycling , don’t forget the traffic lights.

原句子She tried her best though she was rather poor in health.

简化后的句子：

She tried her best though rather poor in health

【六】两个简单句简化为一个定语从句简化

(简单句1)This is the desk.

(简单句2)I have used the desk for many years.

简化为一个定语从句如下

This is the desk (which/that) I have used for many years.

(简单句1) He wants to find a man.

(简单句2)The man knows this area very well.

简化为一个定语从句如下

下面句子中括号里的内容可以省略，句意不变：
