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.

If there were no gravity, we would not be able to walk on the earth. ②与过去事实相反： If You had gone to the party, You would have seen YaoMing.

If there were a heavy snow next Monday, we would not go skating. （二）if虚拟语气条件句的省略倒装。 如果虚拟条件从句中有were, had, should,可把if 省略，把were, had, should 提到主语前面，成为倒装结构。 ①If I were you, I would accept the challenges. ----Were I you, I would accept the challenges ②If you had informed me earlier, I wouldn’t have signed the contract. ----Had you informed me earlier, I wouldn’t have signed the contract. ③If she should be my daughter, I wouldn’t allow her to study abroad. ----Should she be my daughter, I wouldn’t allow her to study abroad.

高中英语语法之虚拟语气讲解
【The Subjunctive Mood】 语气 (mood)是一种动词形式，用以表示说话者的意图或态度。英语中的语气有三种：陈述语气、祈使语气和虚拟语气。 陈述语气(indicative mood),表示所说的话是事实。 祈使语气 (imperative mood),表示所说的话是请求或命令。 虚拟语气(subjunctive mood),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、建议或及事实相反的假设等。 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句及非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句及结果主句都用陈述语气。 如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句及结果主句皆须用虚拟语气。
1. 及现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式 (be的过去式用were), 主句的谓语用should （would, might, could）+动词原形。 如： If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。 （事实是：天在下雨，我们不能出去野餐。表示愿望。） If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。 （事实是：他没来这，他不可能帮助你。表示对他的良好印象。） 2. 及过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （ would, might， could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited. 要是当初她被邀请的话，她就会去参加这次聚会了。 （事实是：当时没有人邀请她，因此，她没有来参加聚会。表示后悔。） If she hadn't called me, I would have overslept this morning. 今天早上，她要是不叫我的话，我就会睡过头了。 （事实是：她今天早上叫我了，我没有睡过头。表示感激。）

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
