知识点总结

1.    用not构成的否定句:主语+助动词/情态动词/ be + not+…

He is not back yet.

We haven’t forgotten you.

You shouldn’t be so silly.

He won’t go, but they will.

Money could not buy happiness.

I like the salad, but I don’t like this soup.

He wants a girl friend, but he doesn’t want to get married.

You didn’t understand what I said, did you ?

You needn’t try to explain.

I didn’t use to like opera, but now I’m getting interested.

I usedn’t to like opera, but now I’m getting interested.

2.    祈使句的否定句:Don’t+动词原形…。

Don’t worry. I’ll look after you.

Don’t believe a word he says.

Don’t be so rude.

3. 非谓语动词(不定式,分词,动名词)的否定式:把not放在to do; doing; 的前面。

It’s important not to worry.

He said he deeply regretted not being able to help.

Not knowing what to do, Shelly asked advice of her friend.

He reproached me for not having told it to him.

4. not与除谓语以外的其他句子成分连用:

Come early, but not before six.

It’s working, but not properly.

I believe he will succeed, though not without some difficulty.

not用在I hope; I believe; I’m afraid; I guess; I suppose; I expect之后,构成省略句。

—Will it snow today ?

—I hope not.

5. 用no构成否定句:no+名词(单,复数,不可数)相当于not+ a +名词/ not + any +名词

The nations of Europe and America have found that no country can produce all its needs without trading.

Take that towel, I have no other.

I can walk no farther.

There is no knowing what will happen.

6. 某些否定副词或代词:seldom; never; hardly; rarely; little; few; none; nowhere; neither等在句中构成否定句:

I can seldom find time for reading.

Mirror tells only the facts, never the poetry.

The rumor came from nowhere.

None but fools have ever believed it.

7. 否定转移:当think; believe; suppose; imagine等动词引导否定意义的宾语从句时,把从句中的not提到主句这些动词前面,是主句变成否定句:

I don’t think she’s at home, but I’ll go and see.

I don’t imagine that he’ll enjoy it.

8.部分否定:

注意部分否定的结构:

Not all…=All…not…

Not both…=Both…not…

Not every…=Every…not…

I don’t remember all the names.

All is not gold that glitters.

It is not found everywhere.

Not everyone likes this film.

9. 用否定形式表示肯定的意义:

注意这些句型:

cannot…too.. / cannot… more: 越…就越好;再…不过了。

You cannot be too careful.

A man can never have too many friends.

常见考法

1.反义疑问句的回答;2.否定疑问句的回答;3.情景对话中肯定否定的确定;4.not与相关副词的搭配;5.全部否定与部分否定等。

误区提醒

1.反义疑问句受汉语影响出错;2.否定疑问句回答时肯定否定弄反;3.固定搭配不熟悉;4.全部否定与部分否定弄混。

【典型例题】

1. —Aren’t you feeling tired ?

  —______, I am rather.

A. Yes          B. No           C. Not at all   D. Never

解析:错选B。受汉语意思影响;否定疑问句的回答方法和反义疑问句前否后肯情况的回答是相同的,即汉语的肯定和否定分别对应英语的no 和yes.千万要注意。正确答案为A。

2. —She isn’t a dancing teacher, is she ?

 —______.

A. Yes, she isn’t                B. No, she is              

C. Yes, she wasn’t                   D. No, but she was.

解析:错选B。原因同上。正确答案为D。

3. —Will you go shopping with us this afternoon?

 —_____but I’ve got quite a lot of homework to do.

A. Of course              B. I’d like to              C. That’s all right       D. No, I won’t

解析:错选D。对方邀请与其一起购物,根据回答的后半句,应该是去不了;但but所提示的信息是受邀请方想去,可是去不了;正确答案为B。

4. —If our parents would listen more to us, they would understand us better.

 —_____. They just expect us to listen.

A. All right   B. No problem    C. Good idea             D. I can’t agree more

解析:错选A。根据题意,此处应该表赞同;因为误把选项D当成是反对。

I can’t agree more .的意思是“我太同意(你的意见了)”。
