英语语法中的倒装、虚拟语气、时态语态还有被动语态各自的分类并且举例说明


倒装的概念与分类

英语句子的结构一般是“主语 + 谓语”,语法上称这种语序为自然语序。但有时由于出于语法结构的需要或修辞的需要,常把句子中的一部分或全部倒转过来,这种语序就是倒装语序。

英语的倒装分为部分倒装和完全倒装。其中部分倒装指的是将谓语的一部分位于主语前,其句式与一般疑问句的相同。如:

She hardly has time to listen to music.

=Hardly does she have time to listen to music.

他几乎没时间听音乐。

而完全倒装则指将谓语动词完全置于主语前。完全倒装一般具有以下两个条件:

①谓语动词是单个(即不带情态动词、助动词或be)的不及物动词,且只限于一般现在时或一般过去时。

②主语只能是名词。

Here comes the bus. 公共汽车来了。

Away went the runners. 赛跑选手们跑远了。

The door opened and in came Mr Smith. 门开了,史密斯先生进了来。

注:若主语为人称代词,则不能用倒装。如:

Away he went. 他跑远了。

虚拟语气用法详解

一、 条件句中的虚拟语气

1. 条件句中虚拟语气的形式

从句中提出一种与客观现实不相符或根本不可能存在的条件,主句会产生的一种不可能获得的结果。条件句中的虚拟语气根据不同的时间有三种不同的形式。

时间

从句谓语形式

主句谓语形式

将来

动词过去式(be用were)

should + 动词原形

were to + 动词

would / should / might / could + 动词原形

现在

动词过去式(be 用 were)

would / should / might / could + 动词原形

过去

had +动词过去分词

would / should / might / could have + 动词过去分词

2. 中的虚拟语气的举例

(1) 将来时的条件句中的虚拟语气。如:

If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话,他就会充分利用他的时间了。

(2) 现在时的条件句中的虚拟语气。如:

If he were free, he would help us. 要是他有空的话,它会帮助我们的。

(3) 过去时的条件句中的虚拟语气。如:

If I had seen the film, I would have told you about it. 我如果看过这场电影,我会把电影内容告诉你了。

3. 运用条件句中的虚拟语气时,须注意的几个问题

(1) 当从句的主语为第三人称单数时,谓语动词若是系动词be时,可用was代替were。但在倒装虚拟结构及if I were you, as it were中,只能用were。如:

If I were you, I would try my best to grasp the chance. 要是我是你的话,我要尽力抓住这次机会。

(2) 有时,虚拟条件句中,主、从句的动作若不是同时发生时,须区别对待。

①从句的动作与过去事实相反,而主句的动作与现在或现在正在发生的事实不符。如:

If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话,我现在也会使工程师了

②从句的动作与现在事实相反,而主句的动作与过去事实不符。如:

If he were free today, we would have sent him to Beijing. 如果他今天有空的话,我们会已经派他去北京了(from www.yygrammar.com)。

③从句的动作与过去发生的情况相反,而主句的动作与现在正在发生的情况相反。如:

If it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的话,庄家会长得更好。

(3) 当虚拟条件句的谓语动词含有were, should, had时,if可省略,而将were, should, had等词置于句首。如:

Should he agree to go there, we would send him there. 要是他答应去的话,我们就派他去。

(4) 有时,句子没有直接给出假设情况的条件,而须通过上下文或其他方式来判断。如:

I would have come to see you, but I was too busy. 我本该来看你了,然而我太忙了。

(5) 有时,虚拟条件句中,主、从句可以省略其中的一个,来表示说话人的一种强烈的感情。

①省略从句

He would have finished it. 他本该完成了。

②省略主句

If I were at home now. 要是我现在在家里该多好啊。

英语被动语态讲解

一、语态概述

英语的语态是通过动词形式的变化表现出来的。英语中有两种语态:主动语态和被动语态。

主动语态表示主语是动作的执行者。巧记为:主动、主动、主去动。

例如:Many people speak English.

谓语:speak的动作是由主语many people来执行的。

被动语态表示主语是动作的承受者,即行为动作的对象。巧记为:被动、被动、主被动。例如:English is spoken by many people.主语English是动词speak的承受者。

主动态和被动态指的是动词形式,是词法概念;而主动句和被动句则指的是句子结构,从而是句法概念。所谓主动句就是由主动态动词(词组)作谓语动词的句子,而被动句则是由被动态动词(词组)作谓语动词的句子。

例如:He opened the door.他开了门。(主动句)

The door was opened.门被开了。(被动句)

二、被动语态的构成

被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach为例说明被动语态在各种时态中的构成。

一般现在时:am/is/are+taught

一般过去时:was/were+taught

一般将来时:will/shall be+taught

现在进行时:am/is/are being+taught

过去进行时:have/has been+taught

现在完成时:have/has been+taught

歌诀是:被动语态be字变,过去分词跟后面。

三、被动语态的用法

(1)不知道或没有必要说明动作的执行者是谁。

例如:

Some new computers were stolen last night.

一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)

This book was published in 1981.这本书出版于1981年。

(2)强调动作的承受者,而不强调动作的执行者。

例如:the window was broken by Mike.窗户是迈克打破的。

This book was written by him.这本书是他写的。

Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证。

歌诀:谁做的动作不知道,说出谁做的没有必要;

动作承受者需强调,被动语态运用到。

四、主动语态变被动语态的方法

(1)把主动语态的宾语变为被动语态的主语。

(2)把谓语变成被动结构(be+过去分词)

(根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式)。

(3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。例如:

All the people laughed at him.

He was laughed at by all people.

They make the bikes in the factory.

The bikes are made?by them?in the factory.

歌诀是:宾变主,主变宾,by短语后面跟。

谓语动词变被动,be后“过分”来使用。

五、含有情态动词的被动语态

含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。

歌诀是:情态动词变动,情态加be加“过分”,原来带to要保留。例如:

We can repair this watch in two days.

This watch can be repaired in two days.

You ought to take it away.

It 虚拟语气倒装资料|虚拟语气三种形式 ought to be taken away.

They should do it at once.

It should be done at once

虚拟语气中的倒装句


如果虚拟语气的条件从句谓语动词中含有were, had, could, should,有时可将if省去,而将条件从句的主语置于were, had, should, could 之后。

Had you invited us, we would have come to your party.

Were I you, I would do more practice after class.

Could she lend us a helping hand, she would do so.

虚拟语气、倒装句具体语法内容。另外还有什么重要的,要举例


虚拟语气

A.用wish表示对现在的愿望时,它所引起的宾语从句中谓语动词形式为:过去式(be动词用were)。

B.用wish表示对将来的愿望时,它所引起的宾语从句中谓语动词形式为:would, could, might+ 动词原形。

C.wish用于对过去的事实表示一种不可能实现的愿望时,宾语从句中的谓语动词形式为:had+动词过去分词或could, would + have +动词过去分词。

(2)had hoped引起的宾语从句中备用语动词形式为would+动词原形,表示一种过去未实现的愿望或令人失望的事。

(3)would (had) rather, would as soon, would sooner和would prefer所引起的从句中要求用过去式表示当时或将来的情况,用过去完成时表示过去的情况,表示希望或婉转的责备

(4)It’s (high, about) time that 句型中that从句中要求用虚拟语气形式,即动词要用过去式。

由连接词in case, so that ,unless, lest ,for fear that引起的状语从句中,谓语动词要用虚拟形式,即should(might, would)+动词原形

(5)虚拟语气用于as if(though)引起的方式状语从句和表语从句中,其动词形式与wish宾语从句的形式相同

(6)其它各种句型, as though, suppose, had rather,

>>>>精品(暖文爽文)在线阅读<<<<

supposing, if only等等

倒装句

1)句首的状语若是由often开头或副词only+状语(副词,介词短语或状语从句等)放在句首时:

Often did I tell him not to make trouble.

2)含有否定意义的副词或连词(如little, scarcely, barely,rarely, seldom,never, no sooner…than, not only,hardly…when…, 等)放在句首时

Not only did we lose our money, but we also came close to losing our lives.

3)副词so, neither, nor, no more用在句子的开头,表示前面

说的情况也适合于另一个人或事物以避免重复的句子,作"也"讲时,

引导的句子用倒装语序,例如:He went to the film last night. So did I.

虚拟语气的倒装形式怎么用


属于部分倒装,当虚拟条件句中含有 were,had,should,could等动词时,可以将if省略,然后将 were,had,should,could 等词移至句首:

1. If he should fail,he would kill himself. →Should he fail,he would kill himself. 万一失败,他就会自杀。

2. If I were you,I would do it at once. →Were I you,I would do it at once. 假若我是你,我就会马上做。 3. If I could do it,I would. →Could I do it,I would.

英语语法中 虚拟语气 倒装的知识点


在if引导的虚拟语气条件从句中,若有should. were . had . 那么在书面语气中就可以省略if,将这几个词提到句首,构成倒装。

however如何用虚拟语气,怎么倒装


你要知道它的用法

however用法详解

1. 用作副词

(1) 表示让步:意为“无论如何”“不管怎样”,用来修饰形容词或副词,其词序为:however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能,用以引导让步状语从句。如:

Phone me when you arrive, however late it is. 你到达之后就给我打电话,不论多么晚也要打。

However much he eats, he never gets fat. 不管他吃多少,他永远吃不胖。

However cold it is, he always goes swimming. 不管天有多冷,他都去游泳。

You won’t move the stone, however strong you are. 不管你力气有多大,也休想搬动那块石头。

However far it is, l intend to drive there tonight 不管有多远,我今晚也要开车到那儿去。

用于此用法时,请注意以下几点:

①此用法属however所有用法中最重要的考点,同学们务请引起高度重视。

②这样用的 however 与 no matter how 大致同义。如:

People always want more, however [no matter how] rich they are. 人总是富了还想再富。

However [No matter how] hard I worked, she was never satisfied. 无论我多么努力地工作,她从来没满意过。

③有时从句谓语可用情态动词。如:

Don’t laugh, however funny it may be. 无论多么有趣也不要笑。

I’ll try to finish it in time, however hard it may be. 无论多么难,我也要按时完成。

④“however+形容词或副词+主语+谓语”有时可以有所省略。如:

I refuse, however favorable the conditions. 不管条件如何有利,我都不干。(conditions后省去了are)

I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小,我宁愿一个人住一间,而不愿意与别人合住一个房间。

A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则,不管如何正确,除非能懂,否则毫无用处。

(2) 表示转折:尤其用于谈及一个既成事实时,表示转折,其意为“可是”“仍然”等。可放在句首、句中或句末,通常用逗号与句子其他成分隔开。如:

My father, however, did not agree. 但是,我父亲不同意。

My room is small; however, it’s comfortable. 我的房间很小,但却很舒服。

He said that it was so; he was mistaken, however. 他说情况如此,可是他错了。

注:however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)。如:

我们都已尽了最大的努力,不过我们还是输了。

误:We all tried our best, however we lost the game.

正:We all tried our best, but we lost the game.

正:We all tried our best; however, we lost the game.

正:We all tried our best. However, we lost the game.

(3) 表示惊奇或强调:相当于how ever的用法,其意为“究竟怎样,到底以什么方式”。如:

However did you get here without a car? 没有汽车你究竟是怎样来的呢?

However does he manage to write music when he is so deaf? 他聋成这个样子,究竟是怎样从事作曲的呢?

2. 用作连词

用作连词,引导方式状语从句,表示“无论以何种方式”“不管怎样”。如:

However it may be, I shall take your word. 无论如何,我将会相信你的话。

However I approached the problem, I couldn’t find a solution. 这一问题我不管怎样都无法解决。

However you travel, it’ll take you at least two days. 无论你怎么个走法,至少要两天时间。

The painting looks wrong however you look at it. 这张画不论怎么看都显得不对劲。
