高中英语语法虚拟语气 教学设计 集团档案编码：[YTTR-YTPT28-YTNTL98-UYTYNN08]
高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。
if only强调所希望的状态并不存在，而wish则表示某事有可能发生。 一、wish用法说明 动词wish后接宾语从句时，从句谓语要用虚拟语气。 要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时（be 动词一律用were）；表示与过去相反的愿望，从句谓语用过去完成时或 would/could+had +过去分词； 表示将来没有把握或不太可能实现的愿望，从句谓语用 would/could/should/might＋动词原形。 I wish I were not so busy.但愿我不那样忙碌。 I wish I were [was] better looking.要是我长得漂亮些就好了。 She wished she had stayed at home.她后悔的是她当时要是留在家里就好了。 I wish you would go with us tomorrow.要是你明天同我们一起去就好了。 I wish you wouldn’t look down on this kind of work.我希望你不要看不起这种工作。 This watch has gone wrong. I wish I had bought a better make.这只表坏了，我真愿意我买的是好一点的牌子。 I wish you wouldn’t smoke any more.我希望你不再抽烟了。 I wish you would be more respectful to your father.我希望你对你父亲更尊敬些。 I wish I could be of some use.我希望我能有什么用处。 二、if only 1.在if only这个短语中，only只是加强if的语气的，不仅能表达说话人的愿望，而且能表达条件。
虚拟语气在as if/as though引导的方式状语从句中1.表示与现在事实相反或对现在情况有怀疑，谓语动词用过去式。 He treats the boy as if he were his own son. 2.表示与过去事实相反，谓语动词用过去完成时。 He spoke as if he had known about it. 3．表示与将来事实相反，(表示将来的可能性不大),用would (might, could)+动词原形 He acts as if he could win in the game . 注意：1.在as if/as though 句中，如果有可能成为事实，用陈述语气。 例：He looks as if he going to be ill. 2.as though或as if引导的状语从句，从句主语和主句主语相同时，从句中可省略主语和部分谓语。 虚拟语气用在lest，for fear that，so that及in order that引导的目的状语从句中表示“以防，以免”等意思谓语动词多用should/could/might+动词原型构成 For fear that it may rain tomorrow, we should bring an umbrella. 由“providing（that） /provided（that）/on condition that/suppose （that）/supposing （that）”引导的条件从句根据情况，1.可以用虚拟语气。 例：suppose/supposing that it rained,we shouldn’t go out. 2.也可以用陈述语气。 例：They are willing to surrender provided they are given free pardon..
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）
虚拟语气详解 虚拟语气表示说话人的主观愿望（往往与客观事实相反），或是表示假象和猜测。虚拟语气无论从形式上还是时态上都比较复杂，需要归类记忆。 虚拟语气大体分为三类：(1) be型虚拟(2) were型虚拟(3) if 条件句及主句虚拟下面会详细说每种虚拟形式的特征和规律，考试时先判断属于哪种虚拟类型，剩下的皆是套路~ （1）be型虚拟（基本是套路） 形式：should + 动词原形，should可以省略 用法：1）表示“命令、建议、要求”等意义词语之后的宾语从句用be型虚拟，常见的词如下: demand, desire, insist, order, ask, command, propose, recommend, suggest, prefer, require, request等 最常见的形式是这类动词后面接着一个宾语从句，则宾语从句的谓语部分要用（should）+ 动词原形来虚拟 例: We demand that the meeting（should）be postponed. The manager suggested that we (should) work together. 注意：有时候你所见到不一定是上述动词引导的宾语从句，而是由上述词变体后所引导主语从句(it做形式主语，如：it is advised/ suggested/ requested/ ordered/ proposed that…)、表语从句或同位语从句 例如：It is required that the students (should) learn a foreign language. (主语从句) The requirement is that all the equipment in the meeting room (should) be checked twice before. (表语从句) We didn’t stand for his proposal that the meeting (should)be postponed. (同位语从句) 只要看到句中有上述动词或其变体，不管词性怎么变、句型怎么变，都用be型虚拟！ 特例：suggest和insist这两个比较特殊，当suggest作“暗示、表明、说明”讲，insist 作“坚持说”讲，后面一般跟的是客观事实，不需要虚拟~这是一个比较重要的考点，体会下面两组句子： We all suggest that a lab (should) be built. 我们都建议建一个实验室。 Her expression suggests that she is angry. 她的表情说明她生气了。 She insisted that we should find the source of the river. 她坚持主张我们应该找到河的源头。 She insisted that she had done nothing wrong. 她坚持说自己没做错事。 suggest 的区别很明显，但insist有点难辨别，一般来说如果insist后面跟的是某种主张，或是坚持要做一件事，那么用虚拟。 2）表示主观看法，常表示“某事是必要的、重要的。。。怎么怎么样的”，尤其是在“ it is +名词/形容词+ that从句”结构中，常见的形容词包括：advisable, desirable, essential, imperative, important, necessary, obligatory, proper, dispensable, impossible, natural, surprising等 例如：It is advisable that you (should) leave now. It is necessary that teenagers (should) take part in outside activities. It is of great importance that smoking (should) be banned in public area.
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．。
虚拟语气在非真实条件句中 ①错综时间条件句: 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表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。否定句时not留在原来位置不变。如： If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars)
虚拟语气 1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。(事实上是不知道) 2. He wishes he hadn't lost the chance. 他真希望没有失去机会。(其实已失去) 3. You wished she would arrive the next day.(would + arrive) 你希望她第二天会到。(事实上她还没到) Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。它仅有两个形式，即be型虚拟式和were型虚拟式。 Be型虚拟]----- be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。其主要用法如下： 1)用于表命令、决定、建议、坚持等词语之后的that分句中 这一用法又分三种情况： a)用在 decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句） 在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。 He ordered that all the books be sent at once. He ordered that all the books be sent at once. we propose that somebody neutral take the chair. She insisted that she go to the south for her holiday. b)用在 advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。（主语从句） It is essential that all the facts be examined first. It was appropriate that thisi tax be abolished. I thousht it advisable that an armed guard stand in readiness. c)用在 decision,decree,demand,instruction,order,requirement,resolution等名词之后的that分句中。 The board has given instructions that the agent fly to Boston. We were faced with the demand that this tax be abolished. Their decision was that the school remain closed. 在这一用法中be型虚拟式能与“should+不定式”交替使用，也能与to-不定式交替使用。 He ordered that the books be sent at once . = He ordered that the books should be sent at onc. = He ordered that the books to be sent at once. 2）用于由if,though等引导的分句中.
虚拟语气和错综条件时间从句区别 You would be much better now if you had taken my advice. （错综时间条件从句） You would have been much better now if you had taken my advice.(虚拟） 假若你当时听我的话，你现在就会好多了 在表示虚拟语气的句子中，条件从句表示的动作与主句表示的动作发生的时间并不一致，这时，谓语动词的形式要根据各自所表示的时间来调整，这种现象叫做错综时间虚拟语气。You would be much better now if you had taken my advice.假若你当时听我的话，现在就会好多了。（从句过去，主句现在）would have been 是与过去事实相反的非真实条件句 一般来说虚拟语气中的混合时态的句子都有具体的时间词来进行提示的，比如 说： If we had arrived at the shopping mall earlier, we would get more gifts now. 如果我们早点来商场的话（过去的时间虚拟），我们现在就可以拿更多的礼物了 （现在的虚拟）。 这是两个不同时间的虚拟语气，有相应的时间词来提示的，now来提示后句的时 间是现在而不是和前面一样的过去。 If we had arrived at the shopping mall earlier, we would have got more gifts. 如果我们早点来商场的话，我们就会拿到更多的礼物了。（已经拿了礼物了，但是实际上过去拿的时候没有拿到那么多） 如果从句和主句都表示过去的，那从句用had done,主句用 would ,could,might,should+have done 如：If you had taken my advice,you would not have been late for the meeting yesterday.如果从句表示过去的，但主句表示现在的，从句用had done,主句用would ,could,might,should+do,如：If you had taken my advice,you would not be late for the meeting now.这种一般都有个时间，如果没有表示时间的词也可以从上下文看出。 虚拟语气的用法错误。
虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句，表达的是说话人的遗憾后悔的语气，愿望以及建议，命令，要求等等的情感，往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后，有可能出现的情况。 虚拟语气的内容主要有三大模块，第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。 下表就是条件从句虚拟语气的基本用法： 通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢？这就像是数学里的排列组合，一边有三种情况，交叉一搭配就出现了好多种情况。不管怎样，我们要遵循一个原则，就是“各自为政”。例如，从句是对过去情况的假设，而主句则是对现在情况的假设，那我们在使用时，从句就用过去完成式，而主句要用would/could do的形式。当然，也不是所有的AB配就是合理的，有时候在具体语境下，会出现矛盾的情况，这时我们就要结合要表达的意思来判断他们是对什么情况的假设，选择合适的形式。一般而言，主句的假设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现主句的现状。因此在此类的完成句子练习中，我们要特别提醒注意时间状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设，主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设，主句是对现在的假设) 8. If Lily didn’t attend today’s party, she could not have the chance to work in the company next week. (从句是对现在的假设，主句是对将来的假设) 9. Had Father followed my travel plan , our family would not stay at home now. (从句是对
虚拟语气在非真实条件句中
①错综时间条件句: 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表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。如：If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars) 如果你有100万元，你会做什么？ We couldn?t have finished the work ahead of time without your help. (=if we
虚拟语气（the subjunctive mood）用法归纳 第一部分：语气的定义和种类 1、语气(mood) 语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度。 2、语气的种类 ⑴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： ① There are two sides to every question. 每个问题都有两个方面。 ② Were you busy all day yesterday? 昨天一整天你都很忙吗？ ③ How good a teacher she is! 她是多好的一位老师啊！ ⑵祈使语气：表示说话人对对方的请求或命令。如： ① Never be late again! 再也不要迟到了。 ② Don’t forget to turn off the light. 别忘了关灯。 ⑶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： ① If I were a bird, I could fly in the air. 如果我是一只小鸟，我就能在空中飞行。 ② I wish I could pass the examination. 我希望我能通过考试。 ③ May you succeed! 祝您成功！ 第二部分：简单句中的虚拟语气 一、情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌、或委婉的语气， 常用于日常会话中。如： ⑴ Would you be kind enough to show me the way to the post office? 请你告诉我去邮局的路好吗？ ⑵ It would be better for you not to stay up too late. 你最好别熬夜到很晚。 二、表祝愿。 1、常用“may+动词原形”表示祝愿，但愿，may须置于句首（多用于正式文体中）。如： ⑴ May good luck be yours! 祝你好运！ ⑵ May you be happy! 祝你快乐！ ⑶ May you do even better! 祝你取得更大成就！ ⑷ May you have a good time. 祝愿你玩的痛快。 ⑸ May the friendship between us last long. 祝愿我们的友情天长地久。 ⑹ May you be happy. 祝你幸福。 【注意】本句型属于部分倒装句型，主语后用动词原形。 2、用动词原形。如： ⑴ Long live the people! 人民万岁！ ⑵ “God bless you,” said the priest. 牧师说：“愿上帝保佑你！” ⑶ Have a good journey! 祝愿你旅途愉快！ 三、表示强烈愿望。（该类型虚拟语气谓语仅用动词原形，第三人称单数也不加“s”） ⑴ God save me. ⑵ Heaven help us. 四、表命令。 1. 命令虚拟语气只能用在第二人称(you)，而且通常省略主语(也就是you)。 2. 句子尾通常加上感叹号。
虚拟语气 一．一般虚拟条件句 (1) 与现在事实相反 ——If I were you, I wouldn’t worry. ——If I had the book at hand, I would read the passage to you. 那么，虚拟语气现在时的句型为： 从句：If + 主语＋动词过去式(be 变were) +… 主句：主语＋would (should ,could ,might ) + 动词原形＋… (2) 与过去事实相反 ——If you had gone to last night’s games, you would have met him. ——If the policeman had arrived earlier, he would have seen the accident. 那么，虚拟语气过去时的结构是： 从句：If＋主语＋过去完成时… 主句：主语＋should (或would,could,might) + 现在完成时… (3) 与将来事实相反 ——If he should come tomorrow, I would give him the dictionary he needs. ——If Mr. Li were to do the experiment tomorrow, he might read the instructions carefully.
那么虚拟语气将来时的句型是： 从句：If+主语＋should (或were to )+动词原形＋… 主句：同虚拟语气现在时的主句结构。 练习： 1.I f this report were more accurate, it __________ an invaluable document. A.were B.had been C.will be D.would be (D) 2.I _______ in trouble if the police had stopped me. A.were B.would have been C.would be D.had been (B) 3.W hat would you do if war _________ out. A.breaks B.could break C.had broken out D. were to break (D) 二、在if引导的虚拟条件句中，若有were, had, should，可省去if,将were, had, should提到主语前，形成倒装。例如： ——Should there be a meeting tomorrow, he would tell you.
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等引起的表语从句与同位语从句 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
虚拟语气 一. 虚拟语气在条件状语从句中的应用 虚拟语气(Subjunctive Mood)这一语法项目几乎是四、六级必考的内容，也是各类英语考试中心测试的重点之一。虚 (win the first prize)的话，我会把奖金送给阿Sam。 If I won/should win/were to win the first prize in the Foshan University Students English Speaking Contest held in May, I would give my reward to Sam. If I win the first …, I will give … 要是我爸是李嘉诚的话，我一定不用为钱发愁。 If my father were Li Jia Cheng, I wouldn’t worry about money. Were my father Li Jia Cheng, I wouldn’t … 要是日本没有发生地震的话，我一定去放炸弹(blast)。 If Japan hadn’t had the earthquake, I would have blasted it. Hadn’t Japan had the earthquake, I … 1
要是将来我有钱了，我一定回来娶你。 If I were rich one day, I would marry you. →Were I rich one day, I … If I should be rich one day, I would marry you. →Should I be rich one day, I … If I were to be rich one day, I would marry you. →Were I to be rich one day, I … (If I am rich one day, I will marry you.) 1. 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过去式(be 一般用were)，主句用would/ should/ could/ might +动词原形。 1) If places ______ a like, there would be little need for geographers.

英语虚拟语气总结（一） 一、概说 英语有三种语气，即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等，祈使语气用于表示请求、命令或警告等，虚拟语气则表示假想或主观愿望：He is honest. 他很诚实。(陈述语气) Don’t be late next time. 下次别迟到。(祈使语气) If I were you I wouldn’t go. 我要是你，我就不会去。(虚拟语气) I wish I had a lot of money. 要是我有很多钱就好了。(虚拟语气) 二、带虚拟条件的虚拟语气 1.真实条件句和非真实条件句 条件句有真实条件句和非真实(虚拟)条件句两种。真实条件句所表示的假设是有可能发生的，而非真实条件句则通常表示一种假想，与事实相反或不大可能会发生：If I have time, I will go with them. 假若我有时间，我就同他们去。(陈述语气) If I were you, I would go with them. 假若我是你，我就同他们去。(虚拟语气) 2.虚拟条件句的三种基本类型 (1)若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”： If you took a taxi，you’d get there quicker. 如果你坐出租车去，你可以快一点到那里。(但你不坐) If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。(可惜我不知道) (2)若与过去事实相反，条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”： If I’d left sooner，I’d have been on time. 要是我早点动身，我就准时到了。(但我动身太迟了) If we had 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。(可惜我们找到他太晚了) (3)若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”： If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。(不过我不打算这样做) 注：① 主句谓语中的should主要用于第一人称后。would, might, could的大致区别是：would表示结果，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
