新概念英语第二册语法总结：虚拟语气
新概念英语第二册语法总结：虚拟语气虚拟语气分三种情况来掌握：1、虚拟条件句。
2、名词性虚拟语气。
3、虚拟语气的其他用语。
一、虚拟条件句：条件状语从句是非真实情况，在这种情况下要用虚拟语气。
1、条件从句与现在事实不一致，其句型为：If 主语＋过去时，主语＋should(could, would, 或might)＋动词原形，如：If I were you, I would study hard.If it rained, I would not be here now.2、条件从句与过去事实不一致，句型为：If 主语＋had＋过去分词，主语＋should(could, would, 或might)＋have＋过去分词，如：If the doctor had come last night, the boy would have saved.If I had not studied hard, I would have failed in the exam last term.3、条件从句与将来事实不一致，句型为：If 主语+should(were to, 过去时)＋do，主语＋should(could...)＋原形do，如：If it should rain tomorrow, we would stay at home.If I were to go to the moon one day, I could see it with my own eyes.If you missed the film to night, you would feel sorry.注意问题：1、If条件句中绝对不可出现"would"。
2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都是遵守上述句型。
3、在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如：Had the doctor come last night, the boy would have saved.Were I to go to the moon one day, I would see it with my own eyes.Should it rain tomorrow, we would stay at home.二、名词性虚拟语气：在表示命令、建议要求、惊叹时的名词性从句中需用虚拟语气，基本句型：主语＋(should)＋动词原形，如：Mother insisted that John go to bed at 9 o'clock.（宾语从句）We suggested that the meeting should not be held.It was required that the crops should be harvested at once.（主语从句）The suggestion that he be invited was rejected.（同位语从句）That is their demand that their wages be increased.（表语从句）注意：在这种句子中绝不出现"would""must""could"等。
虚拟语气完整用法
虚拟语气一、用固定的情态动词表示的虚拟语气1. should +动词原形（有时省略should）（1）用在动词如advise, request, require, suggest, urge,demand, desire,command, insist, order, propose, recommend, 等后的宾语从句中。
例如：1）They requested that we (should) send a invitation to their school.2）He urged that he acquaint and apply the methods.2.用在it is suggested,it has been decided, it is desired, it was proposed,it is required, it was ordered, it is necessary (essential, imperative, important, desirable) that等引出的主语从句中。
例如：1）It is required that we (should) get everything done by tomorrow night.2）It is imperative that the teachers (should) have a thorough knowledge of the subject they teach.3.用在suggestion, motion, proposal, order, recommendation, plan, idea, requirement等引起的表语从句和同位语从句例如：She drives her vessel carefully lest she should lost her way.4．用在表示比拟的方式状语从句中例如：He laughed as if he had never been happier before.5．用在表示虚拟情况的定语从句中例如：It is high time you stop bitting your child.6．用在某些表示主观愿望的名词从句中例1：I wish I were as tall as you.例2：He insisted that we (should) catch up the first bus in the morning.7．用在婉转的请求、建议、批评等句子中例1：Could you hand me some pepper例2：You might have told me earlier.例3：Hadn’t you better go and see you lover8．用在表示祝愿的简单句中例1：Long live world peace.例2：May you best.二．虚拟语气谓语动词的几种表现形式:1．用于虚拟条件句中虚拟条件句及其主句的谓语形式可归纳如下：从句谓语主句谓语与现在事实相反were, did would (should, could, might) + v.与将来事实相反should do, would (should, could, might) + v.（可能性极小）were+to+v.与过去事实相反had done would (should, could, might) + have done例1：I could definitely see the final score if I had the time.例2：How nice it would be if you could bring a gift.例3：Thay might have arrived on time if the car haven’t broken down on the road.如果条件从句中包含有were, had, should或could，有时可把if省略掉，但这时要把were, had, should或could放在主语前面（这种结构在口语中较少使用）。
虚拟语气句型及其表现形式
虚拟语气句型及其表现形式英语句子根据语气可以分三种：陈述语气，祈使语气和虚拟语气。
【概念】虚拟语气常用来表示假设、愿望、猜测、比喻或决定、主张、建议和命令等。
虚拟语气主要用于以下一些情况：一．在由if引导的非真实条件状语从句中If he were not ill in bed, he might come to class.If I hadn’t forgotten your phone number, I should have called you last Sunday.If I were to do it again tomorrow, I might do it in different ways.注意：⑪如果从句中有助动词had, should, were，可以省略if，并采用部分倒装形式，但如果从句中没有，则不能这样做。
例：Had he seen you yesterday, he would have asked you about it.Should it (Were it to) rain tomorrow, the crops would be saved.小练习：If he were not ill in bed, he might come to class.__________________________________________.If I had enough money, I would buy a new car.__________________________________________.⑫如果主句的谓语和从句的谓语在时间上不一致，采用混合时间虚拟。
如一个事情发生在过去，一个是现在发生的等。
这时动词的形式要根据它所表示的时间来调整。
例：If I were you, I would have attended the lecture.如果我是你，我就去听演讲了。
