虚拟语气是考研英语阅读理解、完形填空和翻译中一个很常见的语法现象。尤其是在阅读理解中，推理题，这个决定学生能不能从40分的阅读中夺得30分以上的一个题型。而我们此处的虚拟语气是推理题经常出选项的地方。从1986年到现2014年，其出现的频率是很高的。同时，英语二中虚拟语气也是个考点。但是其形式多，很多考生在判断辨识和使用上有一定难度。虚拟语气的考点一般在考研中有四大类：if 引导的从句类;从句中(should)do 句型;特殊句型类以及单用句型类。之前我们学习了if 引导的从句这个第一类别。那下面就其他三个考点带领大家一起继续学习虚拟语气。
(一)从句中的(should)do 句型
(1)英语中有些表示要求，建议、提议、命令、意愿等的形容词、动词和名词，其后若
跟随有主语从句、宾语从句、表语从句或同位语从句，从句中的动词要求要用虚拟语气形式，
即动词原形或“should+动词原形”。
属于该类的常见形容词有：advisable， desirable, essential, imperative,
insistent, keen , necessary, preferable, urgent, vital等。
例1 .If cities are to remain pleasant places to live in at all, however, it
seems imperative, not only that communications in transport should beimproved, but
also that communication between human beings should be kept smooth and polite。
(1989年阅读3)
例2. The board deemed it urgent that these files should be printed right away.
(1993年单选1)
例3.I don’t think it advisable that he should be assigned to the job since
he has no experience whatsoever. (1993年改错64)
例4.It’s essential that people be psychologically able to resist the impact
brought about by the transition from planned economy to market economy. (1996年
改错12)
常见的动词有advise, ask , beg , decide , demand, desire,
determine,insist,intend,maintain,move,propose,order,recomm-end,request,require,
resolve,suggest,urge等
例5. This year, it was proposed that system be changed: Horizon 2020, a new
program to be enacted in 2014, would not have such a category. (2013年新题型) 例6.Rather than concluding that children make parents either happy or miserable, Senior suggests we need to redefine happiness: instead of thinking of it as something
that can be measured by moment-to-moment joy, we should consider being happy as a past-tense condition。(2011年阅读4)
例7 It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free-market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference。(2011年英语二阅读4)
常见的名词有advice, decision, demand, desire, insistence, instruction, order, preference , proposal, recommendation, request, requirement, resolution, suggestion 等。
例8. The suggestion that athletes should compete as individuals, or in
non-national teams, might be too much to hope for。(1992年阅读3)
(2)由lest, for fear that, in case 引起的从句也多用“should+动词原形的形式表示虚拟语气。”
例9 They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth。(2003年阅读2)
例10 What has happened is that people cannot confess fully to their dreams, as easily and openly as once they could, lest they be thought pushing, acquisitive and vulgar。(2000年阅读5)
(二)特殊句型类
考研的文章中有时会出现由单词或短语印出来的从句，如果是现在的情况，要用一般过去时，如果是过去的情况，要用过去完成体。
(1)it is about/high time (that) “是…时间了”其要表达的含义是“早该”，也就是说是目前还没发生，所以用虚拟语气。
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。
考研英语十二大基础语法体系 对于任何英语句子，要分析其结构，这样才能找到英语语言的规律。每种语言都有它的难点，汉语的难点在于汉语不是拼读语言，汉字很难写，而且有四种声调。其实，许多接触过多种外语的人都认为，英语的语法比法语、德语、俄语、日语等都简单，是最容易学的。著名语言学家乔姆斯基说过，语法是内生的、也就是随着语言的诞生而诞生的。因此，学习语法和学习语言是相辅相成的。 一、英语动词的时态 （一）英汉两种语言在时态表达方式上的差异： 英语的词类与汉语的不同。汉语词类形态稳定，比如“书”这个字，“一本书”、“三本书”都一样，没有词形变化。英语就不同了，book, books仅从词形上就能知道是单数还是复数。 动词是英语中变化最多、最复杂的词类。有人说，学好英语就是学好动词，此言甚是。同一个动作或状态分别在不同时间发生或存在，表达这个动作或状态的动词就要用不同的形式，这就是时态。 （二）英语动词的形式： 英语的时态是通过动词的变化来体现的。因此，了解动词的形式及其变化规律非常重要。英语的实义动词有以下五种形式： (1)动词原形：动词原形在句子中形式不变。主要用于主语为非第三人称单数的一般现在时，情态动词之后， 或根据语法规定必须用动词原形的其他情况。 (2) 一般现在时第三人称单数形式（简称现单三）：主要用于主语为第三人称单数的一般现在时。 (3) 过去式：主要用于一般过去时。 (4) 现在分词：主要用于进行时态，或语法规定的其他情况。 (5) 过去分词：主要用于完成时态，或语法规定的其他情况。 动词一般现在时第三人称单数（现单三）的构成，见下表：
即某些字母组合的不规则动词有一定的规律。如：weep→wept, sleep→slept, sweep→swept 以上每个时间段中分别有四种状态：一般、进行、完成和完成进行。因此我们便有了四四一十六个时态。 态（一般、进行、完成、完成进行）。 比如在“They are doing their exercises.”这个句子中，动词由原形do 变成are doing 的形态，说明这个事情是发生在现在、并处于正在进行的状态当中，所以叫现在进行时； 在“They have done their exercises.”这句中，动词由原形do 变成have done的形态，说明这个事情是发生在现在、并处于完成的状态，所以叫现在完成时； 在“They always do their exercises.”中，动词用原形do 的形态，说明这个事情是发生在现在、并且是一般情况下永远如此，所以叫一般现在时。 在这三句话中，动词do 虽然用了不同的形态，其意义没有变化，而是事情发生的时间和状态变了。其余类推。 （三）时态详解 16个时态中，常用的有12个：一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时、现在完成进行时和过去完成进行时。其他时态很少单独使用。 下面把各种时态的构成和用法做一个全面的介绍。
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: 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）
凯程考研，为学员服务，为学生引路! 考研英语语法虚拟语气解析（二） 六、个别特殊短语 would rather，had rather，had better，would （just） as soon， would sooner 均作 "但愿，宁愿”讲时： （一）后接动词原形，表示现在或将来的一种主观愿望或选择 例句：1 would rather go there with you ，because you are the only person that I have been acqua in ted with. 分析：该句是复合句，定语从句that I have bee n acqua in ted with 修饰the only person。 译文：我宁愿和你一起去那儿，因为你是我在这里唯一熟悉的人。 （二）后接从句，从句动词一般用一般过去时表示现在或将来的愿望，动词用过去完成时表示过去的愿望 例句：I d rather he stayed there，because weather is said to be somewhat worse accord ing to the n ews. 分析：该句是复合句，weather is said to be...是it is said that...的变形。 译文：我希望他待在那儿，因为据新闻报道天气将会很恶劣。 例句：I d rather you had not bee n so rude to her，she was a new comer after all. 分析：该句是复合句，其中after all意为"究竟，毕竟”，you had not been so rude to her 表示与过去事实相反假设。 译文：真希望你不要对她那么粗鲁，毕竟她是新来的。 七、as if/as though引导的方式状语从句 表示“仿佛，好像”时也用虚拟式，从句中动词用一般过去时（be用were）表示与现在 相反假设；动词用would/could/might+动词原形表示与将来相反假设；动词用过去完成时表示与过去相反假设。 例句：The rats develop bacterial infections of the blood as if their immune system —the self protect ing mecha nism aga inst disease—had crashed. 分析：该句是复合句，as if their immune system had crashed 是方式状语从句，两个破 折号间的内容是对system做进一步的解释。 译文：老鼠感染血液病毒后，似乎它们的免疫系统一一即抵御疾病的自我保护机制一—被彻底摧毁了。 例句：But it s not as if earlier times didn t know perpetual war，disaster and the massacre of innocents.（选自2006 年Text 4） 分析：该句是复合句，as if引导的方式状语从句在句中作表语。 译文：但是这不是说以前的时代没有经历过连续不断的战争、灾难和滥杀无辜。 另外，as if（as though）后面的从句也可用陈述语气，尤其在it looks/seems as if（as though）结构中。 例句：The sun rises in the east and sets in the west，so it seems as if the earth is circling round the sun.
虚拟语气 英语中的语气分为陈述语气、祈使语气、虚拟语气三类。 虚拟语气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。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。 如果假设的情况可能发生，是真实条件句，这种情况下谓语用陈述语气。如：If time permits, we'll go fishing together.如果时间允许，我们就一起去钓鱼。 如果假设的情况是不存在的或不大可能发生的，则是虚拟条件句。如：If you had come yesterday, you would have met that famous professor.如果你昨天来，你就会见到那位著名的教授了。（隐含的事实是：你昨天没来，也没见到那位著名教授）。 虚拟语气的基本形式和用法在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气。 1. 含有条件状语从句的复合句 wish（would rather）+宾语从句 suggest（…）+宾语从句 2. 主语从句 It is + adj./p.p/n.+ that+ S+ (should) +do 表语从句S+is that +s + (should) +do 同位语从句 S+that +s +(should) +do 3. 定语从句 It is (high) time that + S + did 用过去式表现在情况 1. 时态后退型用过去完成式表过去 两种形式用过去将来表将来 2. should+动词原形型 内容详述 I. 含有条件状语从句的复合句(以do为例;S=主语) 时间条件状语从句主句 与现在事实相反的假设 If +S+did…S+would/should/could/might+do… 与过去事实相反的假设 If +S+had done… S+would/should/could/might+have done… 与将来事实相反的假设did… If+S should do were to do S+would/should/could/might+do… 注意事项： 1．倒装句。如果条件句中含有功能词had，should，were时，可以省去If，把功能词提前，构成倒装句。 2．错综条件句。若条件句和主句动作不存在同一个时间，则谓语形式应根据具体情况而定。3．If there weren't/had not been +…=without… 4．If it were not for…/ If it hadn't been for…= but for… 5．otherwise+虚拟语气的句子 6．虚拟语气的句子，but+ 陈述事实的句子 II. 虚拟语气用在宾语从句中 sb. did …(希望现在用过去式) 1. wish+that sb. had done…（希望过去用过去完成式） sb. would/should do（希望将来用过去将来） 2. would rather后的从句要用虚拟语气。 时间从句
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．。
考研语法精讲 第四讲虚拟语气 1.什么是虚拟语气 【2010】Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influential, those selected people will do most of the work for them. 【2007】If you were to examine the birth certificates of every soccer player in 2006’s World Cup tournament you would most likely find a noteworthy quirk: elite soccer players are more likely to have been born in the earlier months of the year than in the later months. 英语语气：（1）陈述（2）祈使（3）虚拟 虚拟语气： 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、建议或与事实相反的假设等 【2003】If railroad charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. 【2007】If you were to examine the birth certificates of every soccer player in 2006’s World Cup tournament，you would most likely find a noteworthy quirk: elite soccer players are more likely to have been born in the earlier months of the year than in the later months. 【2008】In the early 1960s, Wilt Chamberlain was one of the only three players in the National Basketball Association (NBA) listed at at over seven feet. If he had played last season, however, he would have been one of 42. 2.虚拟语气在条件从句中的应用 ①If 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。） ②If 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。） ③She 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。）
高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它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 A. 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。 We are not ready. Did it rain all day yesterday? What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使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 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与非真实条件句(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，句中的条件从句与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，句中的条件从句与结果主句皆须用虚拟语气。 1. 与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. 与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.
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(the subjunctive mood,又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。 一、动词的语气 语气用来区别讲话人对某一行为或事情的看法和态度。英语中的语气(mood有三种,分别是陈述语气、祈使语气和虚拟语气。 1.陈述语气 陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。 Where there is a will, there's a way. 有志者事竟成。 Can you help me carry the box upstairs 你能帮我把箱子搬到楼上吗? How I missed the life in the countryside! 我多么想念乡村的生活啊! 2.祈使语气 祈使语气表示说话人向对方提出请求或下达命令。 Come this way,please! 请这边走。 Don't make any noise, will you 别吵,行吗? Do be careful when crossing the street. 过马路时一定要小心。 3.虚拟语气 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。 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。 I wish it were spring all the year round. 但愿四季如春。 May good luck be yours! 祝你好运! 二、条件句中的虚拟语气 英语中条件从句有两类,一类是真实条件句,另一类是非真实条件句。如果假设的情况可能发生,是真实条件句;如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。 A.真实条件句 真实条件句表示的假设是可能发生或实现的,主句和从句的谓语动词都要用陈述语气。 If he doesn't come at 8, we won't wait for him. 如果他八点不来,我们就不等他了。 If a flood happened in the past, there was usually a great loss of life and property.过去发生洪水的话,常有很大的生命和财产损失。 We shall go there unless it rains tomorrow. 如果明天不下雨,我们将去那里。 I'll let you use my bike on condition that you keep it clean. 如果你能保持车子干净,我就让你用我的自行车。 B.非真实条件句 在含有非真实条件句的复合句中,主句和从句的谓语动词都要用虚拟语气,其构成有三种形式: 与现在事实相反if条件句的谓语:were did
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
