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
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．

Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) 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1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。
一．虚拟语气用于条件状语从句中 1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。 If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生：条件状语从句：①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况 (1). 混合/错综型虚拟语气 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，称为‘错综条件句’，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.(从句说的是过去，主句是现在) If I were you, I would have taken his advice.(从句是现在，主句是过去) （2）省略if的虚拟语气
高中虚拟语气精讲 英语动词有三种语气，陈述语气，祈使语气和虚拟语气。 定义：用来表示说的话不是事实，或者是不可能发生的情况，而是一种 愿望，建议，假设的语气叫虚拟语气。 ●虚拟语气在条件状语从句中的用法。 假如我有足够的钱, 我就去环游世界. If I had enough money, I would travel around the world. 假如我是你, 我就不会说那样的话. If I were you, I would not say that. 假如我听了你的建议, 我就不会犯错误了. If I had taken your advice, I wouldn’t have made a mistake. 假如明天下雪的话, 我就不去野营了. If it should rain tomorrow, I wouldn’t go camping. ●有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个 主句或者一个条件从句。 ●假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致， 叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间 而定。(“各归各”的原则） If the weather had been finer, the crops would be growing still better. 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. If I had had time, I would have run round that lake again. Had I had time, I would have run round that lake again. If there should be a flood, what should we do? Should there be a flood, what should we do? 没有阳光，人们的生活将于今天的截然不同。 Without sunlight, people’s life would be different from today. 要是没有你的帮助，我就不能完成那项工作。 But for your help, I wouldn’t have finished the work. With favorable winds, we might have arrived there in two days. ●with, or, otherwise, but, however 引导的从句如与事实不符，用虚拟 My parents lent me the money. Otherwise, I couldn't have afforded the trip.我父母借钱给我了。否则，我可付不起这次旅费。（虚拟） Shut the window, otherwise it'll get too cold in here. （非虚拟） I'm lucky that I'm interested in school work, otherwise I'd go mad.
