高中英语虚拟语气知识点
高中英语虚拟语气知识点
1）虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气在条件句中应用比较多。
2）条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
16.1 真实条件句用于陈述语气，假设的情况有可能发生。各种结构参见下表：
句型条件从句主句
一般现在时shall/will + 动词原形
祈使句
情态动词一般现在时
例如：If he comes, he will bring his violin. 如果他来，会带小提琴来的。
典型例题
The volleyball match will be put off if it ___.
A.will rain
B. rains
C. rained
D. is rained
答案B。真实条件句主句为将来时，从句用一般现在时。
注意：
1）在真实条件句中，主句不能用be going to表示将来，该用shall, will.
（错）If you leave now, you are never going to regret it.
（对）If you leave now, you will never regret it.
2）表示真理时，主句谓语动词不用shall （will）+动词原形，而直接用一般现在时的动词形式。
16.2 非真实条件句
1）虚拟语气可以表示过去，现在和将来的情况，时态的基本特点是时态往后推移。
a. 与现在事实相反的假设
条件从句主句
一般过去时（be用were）should（would）等+动词原形
例如：If they were here, they would help you. 如果他们在这儿，会帮助你的。
含义：They are not here, they can’t help you.
b. 与过去事实相反的假设
条件从句主句
过去完成时should（would）等+ have+ 过去分词
例如：If he had come yesterday, I should / would have told him about it.如果他昨天来的话，我会把这件事告诉他的。
含义：He did not come yesterday, so I did not tell him about it.
c. 表示对将来不大可能发生的事情的假想
条件从句主句
一般过去时should/would等+ 动词原形
were+ 不定式
should+ 动词原形
例如：If you succeeded, everything would be all right. 如果你将来成功了，一切都会好的。
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right.
含义：You are not likely to succeed, everything will be what it is now.
16.3 混合条件句
有时，主句与从句的动作发生在不同的时间，主句从句谓语动词的虚拟语气形式因时间不同而不同，这种条件句叫做混合条件句。例如：
If you had asked him yesterday, you would know what to do now. 如果你昨天问过他，今天就知道做什么了。
（从句与过去事实相反，主句与现在事实相反。）
If it had rained last night（过去）, it would be very cold today （现在）.如果昨晚下过雨，今天就会很冷了。
16.4 虚拟条件句的倒装
虚拟条件句的从句部分含有were, should, 或had时, 可省略if，再把were, should或had 移到从句的句首，实行倒装。例如：
Were they here now, they could help us. =If they were here now, they could help us.他们现在在的话，就会帮助我们了。
Had you come earlier, you would have met him. =If you had come earlier, you would have met him.你来得早一点，就碰到他了。
Should it rain, the crops would be saved. =Were it to rain, the crops would be saved.假如下雨，庄稼就有救了。
注意：在虚拟语气的从句中，动词\'be\'的过去时态一律用\"were\"，不用was，即在从句中be用were代替。例如：
If I were you, I would go to look for him. 如果我是你，就会去找他。
If he were here, everything would be all right. 如果他在这儿，一切都会好的。
典型例题
_____ to do the work, I should do it some other day.
A. If were I
B. I were
C. Were I
D. Was I
答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do, 而不能说Weren\'t I to do。
16.5 特殊的虚拟语气词should
1）在主语从句中的应用
It is demanded / necessary / a pity + that…等结构的主语从句，谓语动词用should 加动词原形，should 可省略。
It is 可用的词有三类that （should）do
suggested, ordered, required, proposed, demanded, requested, insisted等
important, necessary, natural, imperative, strange等
a pity, a shame, no wonder等
2）在宾语从句中的应用
在表示命令、建议、要求等一类动词后面的从句中，像order, suggest, propose, require, demand, request, insist, command, insist + （should）do等。例如：
I suggest that we （should）hold a meeting next week. 我建议下周召开个会议。
He insisted that he （should ）be sent there.他要求被派到那儿去。
注意：如suggest, insist不表示\"建议\" 或\"坚持要某人做某事时\"，即它们用于其本意\"暗示、表明\"、\"坚持认为\"时，宾语从句用陈述语气。
判断改错：（错）You pale face suggests that you（should）be ill.
（对）Your pale face suggests that you are ill.
（错）I insisted that you（should）be wrong.
（对）I insisted that you were wrong.
3）在表语从句，同位语从句中的应用
suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气，即（should）+动词原形。例如：
My idea is that we（should）get more people to attend the conference.我的想法是让更多的人来参加会议。
I make a proposal that we（should）hold a meeting next week.我提了个建议，下周我们开个会。
16.6 wish的用法
1）wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为：
主句从句
从句动作先于主句动词动作（be的过去式为were）现在时过去时
从句动作与主句动作同时发生（had + 过去分词）过去时过去完成时
将来不大可能实现的愿望将来时would/could +动词原形
例如：I wish I were as tall as you.我希望和你一样高。
He wished he hadn\'t said that. 他希望他没讲过那样的话。
I wish it would rain tomorrow. 我希望明天下雨就好了。
2）wish to do；wish sb / sth to do。例如：
I wish to see the manager. = I want to see the manager. 我希望见一见经理。
I wish the manager to be informed at once. （= I want the manager to be informed at once.）我希望经理能马上得到消息。
16.7 比较if only与only if
only if表示\"只有\"；if only则表示\"如果……就好了\"。If only也可用于陈述语气。例如：
I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。
If only the alarm clock had rung.当时闹钟响就好了。
If only he comes early.但愿他早点回来。
16.8 It is （high）time that
It is （high）time that 后面的从句谓语动词要用过去式或用should加动词原形，但should 不可省略。例如：
It is time that the children went to bed. 孩子们该睡觉了。
It is high time that the children should go to bed.
16.9 need \"不必做\"和\"本不必做\"
didn\'t need to do表示过去不必做某事, 事实上也没做。
needn\'t have done表示过去不必做某事, 但事实上做了。例如：
John went to the station with the car to meet Mary, so she didn\'t need to walk back home.
约翰开车去车站接玛丽，所以她不必步行回家了。
John went to the station with the car to meet Mary, so she needn\'t have walked back home.
约翰开车去车站接玛丽，所以她本不必步行回家了。（Mary步行回家了，没有遇上John 的车。）
典型例题
There was plenty of time. She ___.
A. mustn\'t have hurried
B. couldn\'t have hurried
C. must not hurry
D. needn\'t have hurried
答案D。needn\'t have done. 意为\"本不必\"，即已经做了某事，而时实际上不必要。
Mustn\'t have done 用法不正确，对过去发生的事情进行否定性推断应为couldn\'t have done, \"不可能已经\"。must not do 不可以（用于一般现在时）。

高中英语虚拟语气详细讲解大全
高中英语虚拟语气详细讲解 虚拟语气 什么是虚拟语气？是的，我们要学习虚拟语气就必须先弄明白它的概念。 虚拟语气包含两种：一种指与事实相反或不可能发生。“虚拟条件句+虚拟主句”的结构都属于这一类；even if、even though、as if、as though引导的状语中如果需要用到虚拟语气也属于这一类；wish、would rather后面接的宾语从句表示不可能实现的愿望，还是属于这一类。 另一种指与事实实际是否发生没有直接关系。如和suggest、order、demand等表示建议、命令、要求等相关的名词性从句都属于这一类。 大家知道以上两类虚拟语气后，我们就从从句的角度来系统学习虚拟语气。紧跟小简老师的步伐哦！ 一. 虚拟条件句中的虚拟语气 1、表示与现在事实相反的情况 从句：If+主语+did(be动词用were) 主句：主语+ should/would/might/could+do
If I were you,I would take an umbrella. 如果我是你，我会带把伞。（事实：我不可能是你） If I knew his telephone number,I would tell you. 如果我知道他的，我就会告诉你。（事实：不知道） If there were no air or water,there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) 2、表示与过去事实相反的情况 从句：If+主语+had+done 主句：主语+should/would/might/could+have done If I had got there earlier,I should/would have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话） 3、表示与将来事实相反的情况
高中英语虚拟语气知识点及练习
高中英语虚拟语气知识 点及练习 内部编号：（YUUT-TBBY-MMUT-URRUY-UOOY-DBUYI-0128）
虚拟语气：虚拟证据表示说的话不是事实，或者不可能发生的情况，而是一种愿望、建议或者与事实相反的假设等，一般常用于正式的书面语中。 一、虚拟语气在if条件从句中的用法： 1、a. If I were you, I would apply for the job. b. If I lived near my office, I would walk to the office. 与现在事实相反，If条件从句谓语：过去式（be用were） 主句谓语：should / would / could / might+动词原形 2、a. If you had been more careful, You could have passed the exam. b. If you had turned off the gas, the house wouldn’t have caught fire. 与过去事实相反，If条件从句谓语：had+动词过去分词 主句谓语：should / would / could / might + have done 3、a. If it should rain tomorrow, we would not go camping. b. if it were to rain tomorrow, we would not go camping. c. If it rained tomorrow, we would not go camping. 与将来事实相反：If条件从句谓语：过去式 / should + v原形 / were + to do 主句谓语：should / would / could / might + do 二、混合虚拟条件句：不同时间的虚拟，各遵守各的规则，如： a. If you had followed the doctor’s advice, you would be quite all right now. 从句叙述与过去事实相反（had + done），主句叙述与现在事实相反（would + v）
高中英语虚拟语气详解和练习(含答案解析)
虚拟语气 第一节语气 英语的动词一般可带有三种不同的语气：陈述语气（Indicative Mood），祈使语气(Imperative Mood)和虚拟语气（Subjunctive Mood）。不同的语气用动词的不同形式（有的还借助句法形式）来表示。 第二节虚拟语气的概念 虚拟语气是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等 (在宾语从句、表语从句、同位语从句)。 第三节虚拟语气在条件句中 １．当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为：错综时间条件句“，动词的形式要根据它所表示的时间作出相应的调整． If you had followed my advice , you would be better now. 如果你听我的建议，你现在就会痊愈了． ２．在条件句中，可省略 if，把were ,had, should 提到句首，变为倒装句式． If you had come earlier, you would have met him. Had you come earlier, you would have met him.
第四节虚拟语气在名词从句中的运用 一、虚拟语气在主语从句中 A.在句型“It is important (necessary, strange, natural) that .... ”中，表示某事 重要、奇怪、自然、必要等；that 后面的从句中的谓语动词用： should + 动词原形（should 可以省略）例如： It’s important that we should take good care of the patient. 重要的是我们要照顾好病人。 这类的形容词还有advisable（可取的），appropriate（适当的），compulsary（必须的），crucial （关键的），desirable（理想的），essential（必要的），imperative（迫切的），important(重要的)，possible（可能的），preferable（更好的），probable（可能的），strange（奇怪的），urgent（急迫的），vital（极为重要的）等。 B. 在It is demanded/suggested/ordered/required/recommended/requested/required/. that-clause句型中从句用(should )+动词原型，表示愿望，建议，请求等主观意愿等。 It is demanded that we should work out a plan. C. 在It is a pity/a shame/ no wonderproposal/recommendation/suggestion/surprise/advice that…..句型中从句也常用(should )+动词原型,表示建议，命令，请求，道歉，怀疑，惊奇等。 It’s a pity that you (should) miss a good chance. 二、用于宾语从句 用于表示命令、建议、要求等一类词后面的宾语从句。 insist, suggest, order, command, advise, propose, require, request, demand, desire etc. 注意：suggest 当表示“暗示、表明“讲时，insist 表示”坚持认为“之意时，应用陈述语气。 The teacher suggested that we should clean the blackboard after class. 老师建议我们课后把黑板擦了。 The smile on his face suggested that he was satisfied with our work. 他脸上的表情表明他对我们的工作很满意． He insisted that all of us be there on time by any means. 他坚持要求我们大家想尽办法按时去那里。 The man insisted that he had never stolen the money. 那个人坚持说他没有偷钱． 三、用于表语从句和同位语从句 在suggestion / proposal / order / plan / advice / idea / request /desire/ recommendation/resolution 等名词后的表语和同位语从句中要用“should＋动词原形” should可以省略． My advice is that you should practice speaking English as often as possible. 我的建议是你要尽可能经常地练习说英语。 The suggestion that the mayor should present the prizes was accepted by everyone. 每个人都接受由市长颁发奖金这一建议。 第五节虚拟语气在其他从句中 1. It is (high / about ) time that…从句中的谓语动词用过去式或should＋动词原形，should 不能省略．
高中英语虚拟语气用法复习总结
虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 语气的种类： （1）陈述语气表示动作或状态是现实的，确定的或符合事实的，用于陈述句，疑问句和某些感叹句。如We are ready.

Don’t smoke here. 2.有时为了强调，主语也可以出现，而且可以是第三人称，谓语动词不加-s或 者-es 如You be quiet. He stand up. 3.祈使语气可以用do加强语气如Do come to see this Sunday. 4.在Let’s 的祈使句后，疑问部分通常用shall we；在Let us后，疑问部分用 will you 如Let’s go out for a walk after supper，shall we? /Let us clean our classroom, will you? 5.祈使句与连词and连用时相当于一个条件句，而and之后则是表示结果。如 Think hard and you will have a good idea. （3）虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气，列表如下：

高中英语虚拟语气知识点
高中英语虚拟语气知识点 1）虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气在条件句中应用比较多。 2）条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 16.1 真实条件句用于陈述语气，假设的情况有可能发生。各种结构参见下表： 句型条件从句主句 一般现在时shall/will + 动词原形 祈使句 情态动词一般现在时 例如：If he comes, he will bring his violin. 如果他来，会带小提琴来的。 典型例题 The volleyball match will be put off if it ___. A.will rain B. rains C. rained D. is rained 答案B。真实条件句主句为将来时，从句用一般现在时。 注意： 1）在真实条件句中，主句不能用be going to表示将来，该用shall, will. （错）If you leave now, you are never going to regret it. （对）If you leave now, you will never regret it. 2）表示真理时，主句谓语动词不用shall （will）+动词原形，而直接用一般现在时的动词形式。 16.2 非真实条件句 1）虚拟语气可以表示过去，现在和将来的情况，时态的基本特点是时态往后推移。 a. 与现在事实相反的假设 条件从句主句 一般过去时（be用were）should（would）等+动词原形 例如：If they were here, they would help you. 如果他们在这儿，会帮助你的。 含义：They are not here, they can’t help you. b. 与过去事实相反的假设 条件从句主句 过去完成时should（would）等+ have+ 过去分词 例如：If he had come yesterday, I should / would have told him about it.如果他昨天来的话，我会把这件事告诉他的。 含义：He did not come yesterday, so I did not tell him about it. c. 表示对将来不大可能发生的事情的假想

If you had followed the teacher’s advice, you wouldn’t fail the exam now. ●假设条件虚拟倒装。条件从句中有should，were，had三个助动 词可以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If it were not for your advice, we couldn’t have got over the difficulties. Were it not for your advice, we couldn’t have got over the difficulties.

高中英语虚拟语气的用法
高中英语虚拟语气的用法 一、考查虚拟语气在条件从句中的用法 时间从句谓语形式（be用were不可改变）主句谓语形式 将来一般过去时(be用were) would/should/might/could+动词原形 现在一般过去时(be用were) would/should/might/could+动词原形 过去现在完成时would/should/might/could+had done （1）If he my advice, he wouldn' t have lost his job. A. followed B. should follow C. had followed D. would follow （2）If we the other road, we might have arrived here in time for the meeting. A. taken B. had taken C. took D. have taken （3） -John went to the hospital alone. -If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 二、考查特殊句型中的虚拟语气 英语中需要使用虚拟语气的特殊句型不多，主理有以下类: 1.“倒装”类虚拟语气 当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。如: If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。. If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。 If we had found him earlier we could have saved his life.→Had we found him earlier we could have saved his life. 要是我们当时早点找到他的话,我们就可以救活他。 注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。如:我如不是警告了你,你就可能丧命了。 正: If I hadn' t warned you, you could have been killed. 正: Had I not warned you, you could have been killed. 误: Hadn' t I warned you, you could have been killed. 另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。 如: Had I time, I would go with you.假如我有时间,我就同你们一起去。句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you. (1) Had I known about this computer program, a huge amount of time and energy____. (2010浙江卷) A.would have been saved B. had been saved C. will be saved D. was saved （2） fired, your health care and other benefits will not be immediately cut off. (2006湖北） A. Would you be B. Should you be C. Could you be D. Might you be 2.“宁愿”类虚拟语气 这里说的“宁愿”主要是指would rather。当它后接句子的时候,句子的谓语通常要用虚
