在考博英语中,语法贯穿考博英语考试。但在考试的时候,语法就成为了考生们极易失分的地方,所以今天小编为大家整理了英语语法中部分倒装的复习内容及方法。详情如下:
部分倒装
1) 部分倒装即只把谓语的一部分(如助动词、情态动词等)放到主语前,或把句子的强调成分提前。
Nor did he let the disease stop him from living the kind of life he has always dreamt about(疾病没有使他放弃过上梦想中的生活)
2) 以否定词开头的句子要求部分倒装。注意下列句子中助动词或情态动词提前、甚至补充助动词的用法:例:Not until yesterday did little John change his mind.(小约翰直到昨天才改变了主意。) In no country other than Britain, it had been said, can one experience four seasons in the course of a single day.(据说除了英国世界上没有哪个能让人在一天中感受到四季变化)
3) 以否定副词开头并加状语放在句首的句子要求部分倒装。这些否定副词有barely, hardly, little, seldom, scarcely…… when, never, no sooner…… than, rarely, no more, not nearly, not only等以及only。 Only in the country can you learn the “true English”.
4)一些如scarcely……when, no sooner ……than, hardly……when引导的主从复合句主句要求使用过去完成式。注意:在部分倒装句中,只有助动词、情态动词或连系动词to be可以置于主语之前,其它部分都要置于主语之后。
5)此外,一些介词+no+名词的结构中需要用部分倒装,这些结构包括at no time; by no means; by no manner of means; for no reason; in no case; in/under no circumstances; in no sense; in no way; on no account; on no consideration; at no point例如Under no circumstances should you lend Paul any money. 注意:
a) 如果含有从句时,只要求主句倒装: 例:Only after he had spoken out the word did he realize he had made a big mistake.(只有当他已经说出那个字后才意识到自己犯了个大错误。)
b) 如果上述否定副词出现在强调句型中的前半部分,不用倒装:
例: It was not until he went abroad that he knew the truth of the fact.(直到他出国以后才了解到事实真相。)
c) 如果hardly, scarcely后面接的是any, ever, at all时,意义类似almost no/ not/ never(几乎不、从不),则无须倒装。
例:Hardly any people invited went there.(几乎没有什么受到邀请的人去那里了。)
6) 由no matter how, however和how引导的状语从句要求部分倒装,因为形容词或副词通常紧跟在这三个引导词后面,然后才是主语和谓语,形成形式上的部分倒装句:
例:I know nothing about this river, neither how long, how wide nor how deep it is.(我一点也不了解这条河,不知道它有多长,多宽或多深。)
7) 由as引导的部分倒装句:
a) 当as作为比较意义时,即用于as + adv. + as结构中时,如果把第一个as省略掉,就形成部分倒装句。
例:Cautious as the rest of her family (was) , she didn't seem willing to give an immediate reply to my question.(正如她家里人一样谨慎小心,她似乎不愿意立即回答我的问题。)
She charged the stairs, quick as a rabbit (ran).(她跑上楼去,跑得象兔子那么快!)
b) 当 as引导让步状语时,和although, though一样,当用作“尽管”之义时,可以用于部分倒装句。
Hard as he worked, he did not pass the exam.(虽然他很用功,但他还是没及格)
c) 表示原因时,为了强调起见,也可以倒装。
例:Tired as he was, we decided not to disturb him.(因为他太累了,我们决定不打扰他。)
d) 等于so时,意义是“也,也是”
例:She worked hard, so/ as did her husband. (她工作很努力,她的丈夫工作也很努力。)
so, neither, nor倒装
除了构成上述倒装句以外,还可以取代上文出现的名词、形容词甚至整句话,构成完全倒装句或部分倒装句。但这两种倒装的意义不同。
a) 当so表示“也,相同,那样”时,通常表示对前一句肯定句的赞同、一致内容,要求使用完全倒装句:
He promised to finish my homework, so did I.
b) so /such ……that句型可以构成部分倒装句,表示强调so /such和that之间的部分:
例:So selfish was she that everyone avoid talking with her.
c)也存在such+be+主语的情况用以强调,例如Such was Albert Einstein, a simple man of great achievements.(阿尔伯特?爱因斯坦是一个有伟大成就的普通人)
d) neither和nor共有4种倒装形式,其含义分别为:
1) 完全倒装时:表示"也不",和上文a)用法正好相反,表示对前一句否定句的赞同或一致内容。
例:You don't know what to do now, neither/ nor do I .(你不知道现在该做什么,我也不知道。)
2) 和其它否定副词连用,表示"也(不)",也要求用完全倒装句:
例:The besieged enemy could not advance, nor / neither retreat could they .(被包围的敌人既不能进,也不能退。)
注意:若把这句话改成:"The besieged enemy could neither advance nor retreat.(被包围的敌人既不能进,也不能退。)"就不必倒装。
She never laughed, nor did she ever lose her temper.
3) 用在肯定句里,构成一般否定倒装:
例:All that is true, nor must we forget it.(那全都是真的,我们可不能忘记。)
当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
