高中英语语法考点纵览
第十九章否定
一、概述
否定是英语中重要的语言现象,英语中的否定结构形式丰富多样,有部分否定、全部否定、双重否定、半否定等以及形式上肯定而意义上否定、形式上否定而意义上肯定和否定语气转移等。

本章将着力探讨上述诸类现象。

二、常用否定表示法
1、部分否定
当代词或副词,如:all、both、every、everybody、everyone、everything、every day、entirely、always、everywhere、altogether、completely、absolutely等与not搭配连用时,表示否定,意为“并非都…,不是每个都…,不是总是…,表示完全…”。

如:
Both of the two boys are not students. =Not both of the two boys are students.
这个句子是个典型的部分否定,意为“并非这两个男孩都是学生”。

不可译为“这两个男孩都不是学生”如果要表达此层含义,应说:
Neither of the two boys is a student.
All is not gold that glitters. =Not all is gold that glitters.发光的不都是金子。

Everybody can’t arrive on time. =Not everybody can arrive on time.并不是每个人都按时到达的。

Everything doesn’t go well with the man. =Not everything goes well with the man.这个男的并不是一切都顺利。

The rich are not always happy.富人并非总是幸福的。

Not every person is kind.并非所有的人都很善良。

I don’t altogether think it is a good plan.我并不完全认为这是好的计划。

His answer isn’t entirely wrong.他的答案并非完全是错的。

对部分否定要注意以下两点:
①当全称代词如上述的all、both、everybody、everyone、everything在部分否定句中作主语时,否定词not可放在全称代词前,也可放在谓语动词前,含义相同。

如:
Not all can pass the test.相当于All can’t pass the test.均表示“并不是所有的人都能通过这次测试”。

②如果要把部分否定变为全部否定,要把上述代词或副词作相应变化,变为全部否定的代词或副词,相应地:both→neither、all→none、everybody→nobody、everything→nothing、everyone→no one、everywhere→nowhere、always→never等。

如:
No all have attended the meeting.(部分否定:并非所有人都参加会议)
None have attended the meeting.(全部否定:没有人参加会议)
The boy doesn’t always do as his parents say.(部分否定:这个男孩并不总是按他父母说的去做)
The boy never does as his parents say.(全部否定:这男孩从不按他父母说的去做)
2、全部否定
英语中表示全部否定时常用no、not、none、nobody、nothing、nowhere、neither、never等去表达。

如:
No people can go above the law.
He didn’t come to school in the afternoon.
Nobody can enter without permission.
Nowhere can you find such a beautiful park.
He has never been to Beijing.
正确理解和辨别部分否定和全部否定非常重要,有利于正确理解和翻译。

试比较:
I don’t he ar anything about the new plan.(相当于I hear nothing about the new plan.)(全部否定:我没听说任何关于这个新计划的风声。


I don’t hear everything about the new plan.(部分否定:我并没有全面听说关于这个新计划的一些风声。

)He doesn’t like all of the flowers.(部分否定:他并非喜欢所有的花)
He likes none of the flowers.(全部否定:这些花他都不喜欢)
I can’t work out both of the questions.(部分否定:我不能把这两个问题都解决了)
I can work out neither of the questions.(全部否定:这两个问题我都不能解决)
3、双重否定
汉语中双重否定便表示肯定,英语中同样如此,双重否定意义肯定,双重否定即同一个句子里出现两个否定词,即否定之否定。

双重否定句表示的意思是肯定的,通常比肯定句的语气重要,翻译时可以译成肯定形式,也可以保持双重否定的形式。

如:
No one never makes a mistake.(人人都会犯错或没有人从来不犯错)
It is not impossible to learn to drive within a month.(在一个月内学会开车不是不可能的)
He doesn’t give help to nobody in trouble.(有困难的人他都帮助)
You can’t make something out of nothing.(巧妇难为无米之炊)
Nothing is impossible to happen in the world.(世上任何事都能发生)
用于表示双重否定的词,结构还有:no…not(不…不)、no(not)…without(不…不…)、no…but
(没有…不)、cannot but(不得不)、cannot help doing(情不自禁)、can’t help but do(不得不)、nothing less than(正是)、none but(除…外别无…)、no choice/alternative but(除…以外别无选择)、not seldom (常常)、not unhappy(高兴)、there’s no doubt/denying/question that(毫无疑问)等。

4、半否定
半否定表示几乎否定或近于否定,常用的这类表示几乎否定的词有little/few(很少,一点儿)、barely (仅仅,几乎不)、hardly(几乎不,简直不)、rarely(很少)、scarcely(几乎没有,简直不)、seldom (不常,很少)等。

如:
There is little milk left in the bottle.
I can hardly understand what the professor said.
He little knows that he has made a big mistake.
Scarcely ways can solve the problem.
I seldom surf the internet.
5、形式上否定而意义上肯定
英语中有些结构看上去形式上好像是否定,但实质内容上表示肯定的含义,要特别关注此类结构的特殊含义。

(1)cannot+比较级
表示“…不能再怎么样了…”。

如:
The answer can’t be better.这个答案好的不能再好了。

The b oy can’t run faster.这个男孩跑得快地不能再快了。

(2)cannot…too
表示“越…越…,再…也不为过”,cannot也可换为can hardly(scarcely, never),too也可改为over、enough等。

如:
You cannot be too careful when walking across the road.
The teacher can’t praise him too highly.
We can hardly love our parents too much.
We can never have friends too many.
I can’t thank you enough.
(3)no(nobody)…but
意为“都…,没有…不…,只有…才…”。

如:
There is no rule but has its exception.
Nobody enters the college but is strongly impressed.
注意:①这种用法中but作为关系代词引导定语从句,相当于that(which,who)not,如上述There is no rule but has its exception.相当于There is no rule that doesn’t have its exception.
②在疑问词或否定词后面but均有否定意义,不论作为代词还是连词均表示双重否定,即表示肯定含义。

如:
No one thinks that his words are true.没有人认为他说的话是真的。

(否定)
No one thinks but his words are true.没有人认为他说的话不是真的或人人都相信他说的话是真的。

(肯定)
There is no one who knows the secret.没有人知道这个秘密。

(否定)
There is no one but knows the secret.没有人不知道这个秘密或人人都知道这个秘密。

(肯定)
(4)never(not)…but(that)
意为“每当…总会…”,相当于not/never…without doing,but(that)可以引导名词性从句、定语从句、条件状语从句、结构状语从句。

如:
I never (don’t) see the pictur e but I recall the old days.相当于I never (don’t) see the picture without recalling the old days.我每当看到这张照片,都会回忆起过去的时光。

It never rains but it pours.祸不单行。

You can’t make progress but (that) you make great efforts.相当于You can’t make progress unless you make great efforts.或You can’t make progress if you don’t make great efforts.你如果不付出努力,你将不会取得进步。

The man is not such a fool but knows the way.这个男的还不至于蠢到不认识路。

(结果状语从句)
But (that) you helped me, I would have died.(条件状语从句,主句要用虚拟语气,这里的but that用法相当于but for)
(5)more often than not
意为“常常,通常”,相当于as often as not。

如:
He goes to school late more often than not.
(6)It was all(that)sb could do not to do
这种结构表示“很难,不得不”。

如:
It was all that he could do not to listen to his father’s suggestions.
It was all she could do not to laugh at the news.
(7)can’t keep from和can’t refrain from
意为“禁不住,不得不”。

如:
The mother can’t help from worrying about his son.
The man can’t refrain from agreeing with the majority.
(8)否定词+without
意为“没有…便没有…,不是没有”。

如:
There is no wave without wind.
The police catch the man not without any evidence.
(9)否定词+till/until/before
意为“直到…才”。

如:
He didn’t worry about his exam till/until/before the result came out.
(10)否定句+and+否定谓语
这种结构表示“只要…就…”。

如:
No one will make progress and not make efforts. =Every one will make progress if they make efforts.
One can’t drive and not learn it. =Anybody that learns it can drive.
(11)疑问句+and+否定谓语
这种结构表示“只要…就…,只要…能不…”。

如:
Can you see the film and not be moved. =Can you not be moved when you see the film.
以上两种情况都可把后面的否定谓语看作并列谓语进行理解。

(12)否定修辞性问句表示肯定
形式否定的修辞性问句表示非常强烈的肯定。

如:
Can’t man change the world? (相当于Man can change the world.)
What has the man not suffered?
(13)否定感叹句表示肯定
Isn’t it a good plan!
What bad crimes can the criminal not commit!
(14)否定形式表示肯定含义的常见短语
①nothing but与none but均表示“仅仅,只有,只…才”与nothing other than同义;nothing but后接非指人的名词,none but后接指人的名词或非指人的名词。

如:
I can eat nothing but a piece of bread in the morning.
We can do nothing but wait.
None but the man can operate the machine in the factory.

He is none other than my father.
④no otherwise than表示“只是,不会其他”相当于only。

如:
He is no other wise interested than in English.

⑤nothing of not表示肯定的含义,相当于very、much、extremely等,多用来强调作表语的形容词或名词。

如:
He is, nothing if not, careful.
She is, nothing if not, a doctor.
⑥not a little、not a few、no little、no few、no small等表肯定含义。

not a little=no little=quite a little=much
not a few=no few=quite a few=many
only a little=but a little=little
only a few=but a few=few
no small=great
no common=peculiar
not a bit=not at all, not in the least
如:
I don’t like the food a little.
In the past, he gave me quite a little help.
The plan is of no little importance.
He has not a few/no few/quite a few friends.
To my no small pride, I got the first place in the game.
There’s only a little/but a little /little milk left in the bottle.
The family has only a few/but a few/few relatives.
I don’t like it a bit.
⑦not the least和not the least of sth表示肯定含义,表示“尤其最重要的”。

He has many good characters not the least is his good humor.
His career is not the least of his success.
6、形式上肯定,意义上否定
英语中某些结构形式上是肯定的,而意义上却是否定的,要特别注意此类结构的特殊含义。

(1)more than…can
此结构表示否定相当于can not,意为“不能,无法,难以”。

如:
That’s more than I can tell you.
The noise is more than I can tolerate.

(3)比较级+than + to + v
意为“不至于…,知道…不该”。

如:

(4)have yet to + v
这种结构相当于have not yet +过去分词。

如:
He has yet to return. =He hasn’t yet returned.
The students have yet to understand the question fully. =The students haven’t yet understood the question fully.
7、由名词、动词(短语)、形容词、副词短语、介词(短语)引起的否定
因为英语中一些词本身就表达否定的含义,所以单个词或短语便可引起否定。

(1)名词引起的否定
常见的这类词有:exception、exclusion、neglect、failure、refusal、lack、shortage、ignorance、loss、absence等。

如:
In absence of the evidence, the police can’t confirm.
The driver broke the traffic rules in ignorance of the traffic lights.
This failure made him confident.
(2)动词或动词短语引起的否定
常见的词有:miss、lose、deny、refuse、negate、fail、exclude、neglect、forbid、refrain、from、lose sight of、keep up with(不落后)、save…from(使…不受)、to say nothing of(更不用说)、not to mention(更不用说)、keep off(不接近)、turn a deaf ear to(拒绝听)、fall short of(缺乏、不足)。

如:Unfortunately, I missed the first train in the morning.
Don’t neglect any detail about the research.

Many villages fall short of drinking water.
(3)形容词引起的否定
常见的词有:far from、short of、absent from、independent of、ignorance of、free from(of)、blind to、deaf to、less than等。

如:
His lecture is far from wonderful.
Anybody shouldn’t be absent from the meeting.
We must learn to be independent of our parents.
the least…或the last表示否定,后接不定式或定语从句作定语,表示“最不可能,最不愿意”。

如:He is the last man to do harm to others.
That is the least of her mother’s worries.
(4)介词或介词短语引起的否定
常见的词有:without、beyond、past、instead of、in the dark、at a loss、in spite of、but for、beside、but、except、out of、out of the question等。

如:
The man is still in the dark about his illness.
Go hiking in rainy days is out of the question.
Without your help, I couldn’t solve the problem.
What you said was beside the point.
(5)副词短语引起的否定
常见的短语有:not at all、not a bit、not in the least、at no time、much less(still less、let alone)、by no means、in no way、on no account、no longer(more)等。

如:
I don’t like noodles at all.
He can’t speak English, much less (still less, let alone) other languages.
On no account should we give in before failure.
三、否定语气的转移
英汉在表达否定方面有一定的差异,在英语中,否定句子某一成分译成汉语时却否定另一句子成分,这种现象称之为否定语气的转移,只有掌握这种否定语气的转移,才能正确地翻译和理解。

下面将分类阐述否定语气转移的各种用法。

1、否定语气转移为否定谓语
None of us understand it.我们都不理解。

No time can be wasted.时间不能浪费。

No letters were received.没有收到信。

2、否定谓语转换为否定状语
The boy doesn’t study hard.这个男孩学习不努力。

The man didn’t work in the factory.这个男的不在这工厂工作了。

Because of illness, he didn’t go to school as usual.因为生病,他不像往常一样去上学了。

3、否定主句的谓语转换为否定宾语从句的谓语
这类否定转移大多出现在think、suppose、believe、expect、imagine、feel、consider、calculate、say、figure等后面的宾语从句中。

如:
I don’t think the film is interesting.我认为这部电影没意思。

He doesn’t feel he has made progress.他认为他没去的进步。

He doesn’t figure that he breaks the traffic rules.他认为他没有违反交通规则。

I don’t suppose that he will go back on his words.我认为他不会食言的。

反过来,当需要否定这类宾语从句时,不可直接否定宾语从句(即宾语从句中出现not),而要否定主句的谓语动词。

然而,在下列情况下宾语从句中的not不可移到主句的谓语上。

①此种句型只能用于现在时,不能用于其它时态,另外主句谓语动词与情态动词或状语连用时,not 不转移。

如:
I can imagine that they could not finish it in such a short time.
I think all the time that he can’t afford a car.
②当谓语前有强调词时,not不转移。

如:
I did think they were not safe standing on the roof.
③当从句中含有not at all、not a bit、not…enough、c an’t help doing等固定词组时,not不转移。

如:
I believe that they did not know the fact at all.
4、主句部分的否定转换为从句部分的否定
He didn’t leave because he was afraid of his father.并不是因为他害怕他爸他才离开的。

He wasn’t sad because he failed in the exam.并不是因为他没有通过这次考试他伤心。

The accident didn’t ha ppen because he drove quickly.并不是因为他开的快而引起交通事故的。

上述这种否定转移通常用于because引导的原因状语从句中,注意观察上述三个例句的共同特点:because引导的原因状语从句位于主句后且主从复合句间没有逗号。

若because位于句首或主从复合句中间用逗号隔开,在这种情况便不可发生否定转移。

如:
He didn’t leave because he was afraid of his father.并不是因为他害怕他爸他才离开的。

Because he was afraid of his father he didn’t leave. =He didn’t leave, because he was afraid of his father.因为他害怕他爸他没有离开。

5、否定主句的谓语转换为否定同位语从句的谓语
当idea、view、thought、opinion、wish、belief等名词作表语时,可以把后面同位语从句中谓语的否定转移到主句的谓语上。

如:
It isn’t my opinion that the answer is right.我认为答案不对。

It wasn’t my belief that he would harm others.我相信他不会伤害别人。

6、否定介词短语作状语中的介词宾语转化为否定谓语
Under no circumstances should we give in to the difficult.在任何情况下我们都不应该向困难屈服。

At no time can we talk back to our parents.在任何时间我们都不能跟父母顶嘴。

四、总结归纳,提炼精华,从容应对否定
1、全面掌握常用否定的表达法。

尤其关注部分否定,对于部分否定,首先要熟知运用部分否定的场合,然后能够正确翻译和理解,还要学会如何将部分否定转化为全部否定,要掌握全部否定、双重否定、半否定的表示法及含义。

2、对于形式上肯定意义上否定和形式上否定,而意义上否定要注意在具体事例中理解,学会运用分解句子成分的方法进行理解,平时在学习的过程要多积累类似的短语及固定句型。

3、否定语气的转移是本章的重点内容,也是语法中的一个重要知识点,要掌握否定语气转移常见的形式,并能熟练通畅翻译和正确理解。
