小心这些“否定”句
(2013-11-04 12:04:51)英语中有些句子“貌相”(形式)否定,实则表示肯定的意义,甚至表示非常强烈的肯定意义。此类句子尤其容易出现在阅读理解中给考生增加干扰因素。就此语言现象归纳总结如下句型,希望大家能够复习之。
1. can / could not...too
·You cannot be too careful when crossing the street.

3. nothing but表示“只有,只不过”,含肯定意义。例如:
· We could see nothing but water. 我们只看见一大片水。

4. never too...to是对too...to的再否定,表示肯定。例如:

注意: too … not to …和 never (not) too … to

·She is no fool. (She is very clever.) 她绝不是傻瓜。
·There is no question that Mr. Smith is the boss.
毫无疑问,史密斯先生就是老板。
10.双重否定表示强烈的肯定。否定+否定=肯定,加强句子的肯定语气,这样的双重否定句被称之为肯定型双重否定句。例如:

“I will never be unmoved when ever I see the film。

双重否定表肯定的句型分类
1)谓语否定+状语否定
词”;状语否定指“介词+名词/动名词”,要么介词否定,要么名词或动名词否定,而介词否定的形式多表现为一个词,即without。例如:
① You cannot make egg rolls with out breaking
eggs不打破鸡蛋,就无法做出蛋卷来。
(即:有失才有得。)
② He will not do it for nothing他不会无缘无故做这件事。(他做这件事定有企图。)
③ She never came with out reporting some fresh instance of
Wickham's extravagance or
irregularity她每一次来的时候,都会讲些有关威克瀚姆豪华奢侈生活的新鲜事。
2)主语否定+状语否定
主语否定指主语常由no-word(比如no+名词、nobody、none、nothing、noone等,这些词被称之为绝对否定词)来担当,或主语由not来否定。
① In some countries no major business is carried on without eye
contact, requiring face-to-face conversation
在有些国家,一切公事都要面对面地进行,需要当面交谈。
② There is no success without hardships
没有磨难,就没有胜利。(不经历风雨,怎能见彩虹。)
③ None of us will leave school without learning any
thing我们毕业时定会学有所成。
④ Not a student has access to the library without showing his
student card不出示学生证,就进入不了图书馆。
3)主语否定+谓语否定
① Nobody does not believe in him人人相信他。(无人不信他。)
② Not many students will not succeed in passing the
exam大多数同学会通过考试。
4)谓语否定+宾语否定
① I do not have nothing to say我有话要说。
② We can't afford not to believe the missile
attack我们不得不相信这导弹袭击是真的。
5)主语否定+宾语否定
① No one has nothing to contribute to society人人对社会都有贡献。
② Nobody has no access to the sporting
facilities人人都可以使用这些体育器材。
6)主语否定+补语否定
补语覆盖面很广,包括名词、介词、形容词、副词、代词、分词以及不定式等等,这些词本身可以是否定形式(比如代词nothing、nobody等),也可以被否定词修饰(比如not+补语),也可指那些含有否定词缀的形式(比如形容词、分词的否定词缀等)。
① Nothing is nothing at all没有一件事是微不足道的。(凡事都有重要性。)
② No smoking is harmless吸烟有害健康。
③ No place is left unexploited到处都已被开发。
7)否定词+否定意义的动词/名词/形容词/副词
英语中有许多词语虽没有被否定词修饰或不含否定词缀,但它们的意义却完全可能是否定的,这样的词和否定词连用时也会构成双重否定。
① We don't doubt that he will succeed in carrying out the
experiment
我们相信他会做好这个实验。
② There is no denying the fact that your action has affected her
normal life
不可否认,你的行为已经影响了她的正常生活。
③ Comrade Lei Feng was not reluctant to help
others雷锋同志非常乐于助人。
④ For all his years, he is none the less vigorous and active
他虽年老,但仍然生气勃勃,精力旺盛。
8)主句否定+从句否定
前面提到的都是特指简单句中的双重否定句的情况。很明显,英语中主从句的双重否定形式也是普遍存在的。而主从句双重否定的两个否定词分别出现在主句和从句中。主句否定时常借助于一般否定词(即not)或绝对否定词(如no,nothing,nobody,never等);从句否定时同样也可借助于一般否定词或绝对否定词,但也可以使用一些含有否定含义的连词,如until,unless等,或是否定含义的准关系代词but。
① In the neighborhood there is nobody who does not know
me在这儿,我绝对是个名人。
② I never read novels that don't appeal to me我从不看不感兴趣的小说。
③ You cannot take the books away unless you get the special
permission from the dean
除非你有系主任的特批,否则你不能把书借走。
④ There is no rule but has exceptions任何规则都有例外。
11.not...until / till表示“直到……才”,具有肯定的意义。

night.

直到车上坐满了乘客,汽车才开走。

it.人们失去时间后才知道时间的价值

12.“否定词 + so + adj. / adv. + as”结构,从反面表示“最”,是一种强烈的肯定。例如:
· It wasn't so bad as last time! 这次不像上次那么糟!
· None is so blind as those who won't see. 没有比视而不见的人更瞎眼的了。
13.not...for nothing中,not用来否定for nothing,从而加强了谓语的肯定意义。例如:
· He didn't study law for nothing. 他学法律并没有白费。
·Believe me, he did not fly into such a rage for nothing.
请相信我,他勃然大怒是有原因的。
14.否定的感叹句、疑问句常表示肯定意义。例如:

Mansion?
15. 以Why don't you...和Why not ...
开头的疑问句往往表示邀请、建议、指导等,具有肯定意义。例如:

·Hardly/Scarcely had he
19.no sooner … than … 一(刚)……就……;在这个结构中, no sooner 位于主句中,主句用过去完成时,

21. 否定词+比较级( 相当于最高级), 常见的句型是:have never + 过去分词 +
