英语句子中谓语动词的语气有三种:1. 直陈语气(The Indicative Mood)直陈语气用于直截了当地陈述事实、描述状态:He has published quite a number of essays this year .他今年已发表了好几篇论文。
2. 祈使语气(The Imperative Mood)祈使语气用于提出请求、命令、建议或是劝告等:Wait outside until you are asked . 请在外面等候,请你进再进去。
Let's just take a break, shall we ? 我们休息一会儿,好吗?3. 虚拟语气(The Subjunctive Mood)虚拟语气用于表示主观愿望和假设的虚拟情况。
虚拟语气不太顾及事实的存在,它表现出说话人的主观因素比较多。
所以说话人所讲的内容往往是与事实相反的;或是其实现的可能性微乎其微,甚至于没有实现的可能性。
当然,有时为了使说话的语气客气、缓和、委婉,也使用虚拟语气。
例如:I wish you were more careful .但愿你更细心一些。
If I had more money, I would buy a bigger apartment.我要是有再多一点钱,我就买一套更大一些房子。
Would you mind shutting the door ? 劳驾您把门关上。
一、虚拟语气在条件状语从句中的构成和用法1. 表示一种与过去事实相反的假设情况,条件从句中的谓语动词要用“had+过去分词”,主句中的谓语动词要用“would / should / could / might+have+过去分词”。
如:If you had come here yesterday, you would have seen him. 如果你昨天来到这里,你就会看见他了。
2. 表示一种与目前事实相反的假设情况,条件状语从句中的谓语动词要用一般过去式(be动词常用were),而主句中的谓语动词则要用“would / should / could / might+动词原形”。
虚拟语气一、语气的分类语气概述:语气,跟失态和语态一样,也是动词的一种形式,表明说话者的意图、态度和目的。
英语中有三种语气:陈述语气、祈使语气和虚拟语气。
1.陈述语气:用来陈述事实或提出想法,包括肯定、否定例:Recent pressure at work may account for his behaviour.他的行为也许是最近的工作压力导致的。
2.祈使语气:表明说话人提出请求、命令或劝告等例:Calm down and tell me what happened.冷静点儿,告诉我发生了什么事。

H e quick or you’ll be late.快点儿,否则你会迟到。
3.虚拟语气:表示说话人的一种愿望、建议、请求、命令;有时是一种非真实的假设,与事实不符或相反的情况例:If had seen him yesterday, I would have told him the news.我如果昨天见到他,就会把这个消息告诉他了。
二、虚拟语气的用法(一)虚拟语气在条件句中的应用1.虚拟语气主要用在虚拟条件中,表示根本不存在的情况或可能很小的假设虚拟语气用于if条件句中时,主句和从句谓语动词的形式如下:——与现在事实相反:过去式(be一般用were)should/ would/could/might+动词原形——与过去事实相反:had+过去分词should/ would/ could/ might have +过去分词——与将来事实相反:过去式(be一般用were)/should + 动词原形/ were to + 动词原形should/ would/ could/might + 动词原形例:If I had enough money, I would buy myself a computer.我如果有足够的钱,会为自己买一台电脑。

语法知识——虚拟语气1.语气及其种类语气是动词的一种形式,它表示动词的作用和说话人的意图和态度。
英语动词的语气分三种:陈述语气、祈使语气和虚拟语气。
陈述语气表示动作或状态是现实的、确定的或符合事实的。
祈使语气表示动作或状态是说话人的建议、请求、命令等。
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。
2.虚拟语气的形式虚拟语气有两种形式:be型虚拟语气和were型虚拟语气。
Be 型虚拟语气是指不管主语是什么人称,动词一律用原形;were型虚拟语气是指不管主语是什么人称,动词一律用were(即过去时)。
试比较:I hope you can go with us.(表示一种有可能实现的愿望)我希望你能同我们一起走。
I wish you could go with us.(表示一种完全不能实现的愿望)我希望你能同我们一起走。
虚拟语气的用法1.在非真实条件句中⑴表示与现在事实相反:if从句用过去时,主句用should / would / could / might加不定式。
如:If she had time,she would / could / might go with you.如果她有时间,她就会/能和你去。
⑵表示与过去事实相反:if从句用过去完成体,主句用should / would / could / might加不定式完成体。
如:If I had had the money last year,I should / would / could / might have bought a house.如果我去年有了这些钱,我就会/可能买一所房子了。
⑶表示未来实现可能性极小,if从句用should / were to,主句用should / would / could / might加不定式。
如:If there should be / were / were to be something wrong,they would / could / might let you know at once.如果出了什么事,他们会/可能马上告诉你。
语气语气是一种动词形式,表明说话人对某个动作或状态所持的态度。
英语中有三种语气:陈述语气,祈使语气和虚拟语气。
一、陈述语气(用来陈述一个事实或对某个事实表示疑问或发表感叹)We are working very hard these days.这几天我们正在拼命工作(陈述事实)Will it be convenient for you?你方便吗?(对事实提出疑问)How cold it is today!今天好冷啊!(对某事发表感叹)二、祈使语气(祈使句以动词原形开头。
只能用现在时态,而且通常针对第二人称,表示请求、建议、或发布命令)Come next time.下次再来Don’t play football in the street.别在街上踢足球注:如果要表示第一、三人称的祈使语气,常用动词let开头Let me go out.让我出去吧Let Mary not do it.让玛丽别做此事三、虚拟语气(表示与事实相反的假设或不太可能实现的愿望)1、虚拟语气在非真实条件句中的运用含有条件从句的句子叫条件句。
条件句可以是真实条件也可以是非真实条件。
如果条件从句表示与事实相符或有可能实现的假设,那么这个句子就叫真实条件句;如果条件从句表示与事实相反或不太可能实现的假设,那么这个句子就叫非真实条件句。
非真实条件句中要用虚拟语气If引导的非真实条件句的虚拟语气用法If引导的非真实条件句虚拟语气用法从句主句对过去的虚拟had done Would/could/should/might+have done对现在的虚拟Did/were Would/could/should/might+do对将来的虚拟did/wereWere to doshould +doWould/could/should/might+do虚拟过去:表示与过去的事实相反的假设虚拟现在:表示与现在事实相反的假设虚拟将来:表示与将来发生的事实相反的假设If I had not seen the film last night, I would have visited Mary.要是昨晚不看电影的话,我会去看玛丽。
语气用来说明事实或就事实提出询问,可用于陈述句、疑问句和某些感叹注:特别说明1、l would/should/could/might主句谓语中的should主要用于第一人称后;would表示结果还表示过去经常常常做某事,might表示可能性,could表示能力、允许或可能性。
比较:If you tried again ,you would succeed. 要是你再试一试,你就会成功的。
(would表结果)If you tried again,you might succeed. 要是你再试一试,你可能会成功的。
(might表可能)If you tried again ,you could succeed. 要是你再试一试,你就能成功了。
(could表能力)2、错综时间虚拟条件句即条件从句与主句所指时间不一致,如从句指过去,而主句即指的是现在或将来,此时应根据具体的语境情况,结合上面提到的三种基本类型对时态作相应的调整:If it had rained last night, the ground would be wet now. 要是昨晚下过雨的话,现在地面就会是湿的。
You would be much better now if you had taken my advice. 假若你当时听我的话,你现在就会好多了。
3、If虚拟条件句的否定(含蓄条件句)常考两个句型:If it weren’t for…和If it hadn’t been for…,其意为“若不是(有)”“要不是”。
如:If it weren’t for water, no plant could grow. 要是没有水植物就无法生长。
If it hadn’t been for your assistance ,we wouldn’t have succeeded.=But for your assistance ,we wouldn’t have succeeded.=Without your assistance ,we wouldn’t have succeeded.4、If虚拟条件句的倒装形式,即把were, had, should置于句首。
例:Were I in school again (= If I were in school again), I would work harder.Had you asked me, I would have told you. (=If you had asked me,…) 编辑本段第二类使用虚拟语气的常见结构或从句:1.*wish与hope接宾语从句的区别在于:hope表示一般可以实现的希望,宾语从句用陈述语气。
wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。
试比较:(1)We hope they will come. (We don’t know if they can come.) (2)We wish they could come. (We know they are not coming.)2.if only 与I wish一样,也用于表示与事实相反的愿望,其后所虚拟语气的时态与wish后所接时态的情况相同:If only she had had more courage! 她再勇敢一些就好了。
If only I had listened to my parents! 我要是当时听了父母的话就好了。
If only she would go with me! 她要是愿意和我一道去就好了!*if only 通常独立使用,没有主句。
3.l would rather后句子用虚拟语气只分现在和过去在would rather, would sooner, would just as soon后的that从句中, 句子谓语习惯上要用虚拟语气,表示"宁愿做什么" ,具体用法为:①一般过去时表示现在或将来的愿望I’d rather you went tomorrow (now). 我宁愿你明天(现在)去。
②用过去完成时表过去的愿望I’d rather you hadn’t said it. 我真希望你没有这样说过。
4.l as if (though)从句用虚拟语气以as if (as though)引导的方式状语从句或表语从句,有时用虚拟语气,则与wish用法相同,例:He acts as if he knew me. 他显得认识我似的。
They treat me as though I were a stranger. 他们待我如陌生人。
He talks as if he had been abroad. 他说起话来好像曾经出过国。
注:两点说明(1) 从句所表示的内容若为事实或可能为事实,也可用陈述语气:It looks as if we’ll be late. 我们似乎要迟到了。
(2) 注意It isn’t as if…的翻译:It isn’t as if he were poor. 他不像穷的样子(或他又不穷)。
编辑本段第三类从句中should+动词原形,should可省略1. 在lest ,for fear that( 以免) ,in case(以防)引导的目的状语从句中的虚拟语气She walked quietly lest she (should)wake up her roommates. 她走得很轻以免吵醒她的室友。

He suggested that we (should) stay for dinner. 他建议我们留下吃饭。
I suggested that you had a secret understanding with him. 我觉得你与他心照不宣。
3. order,suggestion,idea,plan, proposal, advice, demand等名词后的表语从句或同位语从句Our suggestion is that you(should)be the first to go.我们的建议是你应该第一个去。
4.*advice, agreement, command, decision, decree, demand, determination, indication, insistence, order, preference, proposal, request, requirement, stipulation, suggestion, idea, plan, order l “It is (was)+ 紧急重要-- 带感情色彩上述demand/suggest等动词过去分词或important,natural,strange ,necessary,surprised, appropriate等形容词后的主语从句1.
