一、虚拟条件句
概念:一种表示愿望，建议，假设的语气，用来表示说的话不是事实，或者可能性很小的情况。虚拟语气可以用于条件状语从句、主语从句、表语从句、宾语从句等。句中的条件从句与结果主句皆须用虚拟语气。其主句和从句的动词形式具体如下表：
If you were in my position, what would you do? (与现在事实相反)
If I had been you then, I wouldn’t have quarreled with him. (与过去事实相反)
If I saw/ should see /were to see him tomorrow, I would be very happy. (与将来事实相反)
【跟踪演练】
1）.要是我上个学期努力学习英语的话，我就不会考试失败了。
2）.假如他今晚能回来的话，他也许会给你一些建议。
3）.要是我是你，我明天就向老师道歉。
4）.要是我是你，我就听老师的建议。
二、(省if )倒装条件句
如果条件句中有were, had（助动词）或should时，可使用倒装结构，但if必须省略。若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had等缩略成weren’t，shouldn’t，hadn’t置于句首。例如：
1. Had I seen him then, I would have been very happy.
= If I had seen him then, I would have been very happy.
2. Should I have time, I would go with you. = If I should have time, I would go with you.
3. Were I not so busy, I would go with you. = If I were not so busy, I would go with you. 【跟踪演练】
1._____ to do the work, I should do it some other day.
A. If were I
B. I were
C. Were I
D. Was I
2. _____ difficulties, we would be successful.
A. Should we overcome
B. Would we overcome
C. Might we overcome
D. Could we overcome 3. _____ the exam, he would have attended college. A. If he passed B. Had he passed C. Were he passed D. If he should pass 4. _____ five minutes earlier, you could have seen them off. A.If you should arrive B. If you arriveC. Had you arrived D. Should you arrive 三、错综时间条件句 有时，条件从句的动作和主句的动作发生的时间不一致。例如: 一个是过去发生的，一个是现在发生的。这时主从句中的动词形式要根据所表示的时间作相应的调整。例如: 1. If he had followed the doctor’s advice then, he would be quite all right now. 2. Tom would be alive today if the doctor had come sooner last night. 四、含蓄条件句 虚拟条件句中的条件从句有时不表现出来，只暗含在上下文中或用介词短语(without ，but for…) 或连词 (or, otherwise…) 等来表示，这种句子叫做含蓄条件句。例如： Bur for/ Without your help, we wouldn’t have succeeded. = If you had not helped us… I’m really very busy, otherwise, I would certainly go there with you. = If I were not v ery busy… 五、其他形式的虚拟句 1.wish
wish + that did/were 现在 How I wish had done 过去 would / might /could do 将来 【跟踪演练】 (1)我要是记得地址就好了。（真可惜我忘了） I wish I the address. (2)要是他没有离开这里就好了。（他已离开）
How I wish he .
(3)要是明天下雨就好了。（说话人已预料到明天不会下雨）
I wish it tomorrow. 2. as if /though + clause 现在：did /were 过去：had done 将来 : would+动词原形 She loves the baby as if it were her own son. He speaks as if he had been to the United States. 3.表示“建议，命令，要求”等意义时，名词性从句用(should)＋ 动词原形。 (1)一坚持：insist (2) 二命令：order, command (3) 三要求：request, require, demand (4) 四建议：动词advise, suggest, propose, recommend (名词advice, suggestion, proposal, recommendation) 【拓展延伸】 1.The doctor suggested that he (should ） be operated on at once. 2. His look suggested that he stayed up late yesterday. 3.Tom insisted that he was innocent and be set free. 【注意】 (1)suggest 意为“表明，暗示”时，宾语从句不用虚拟语气。 (2)insist 意为“坚持认为，坚持说”时，宾语从句不用虚拟语气。 4. would rather that 现在/将来：过去式 过去：过去完成式 （1）I would rather you paid me now. （2）I would rather you had gone, too. （3）Don’t come. I would rather you came tomorrow. 【跟踪演练】 （1）我真希望你告诉我真相。 （2）我宁愿不再见到你。 （3）我倒希望他们和我一起去。
5. It’s (about/high) time +that 过去式\should +v . 我们该去睡觉了。
6.It’s n ecessary /strange/ natural/ important + that-clause 从句中的动词要用虚拟，即（should ）+动词原形
如： It is important that we ( should ) master a foreign language.
It is strange that she refuse to come to the party.
It’s necessary that we should study hard.

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。
高中英语学习材料 ***鼎尚图文理制作*** 虚拟语气（2） 编稿：牛新阁审稿：王春霞 概念引入 上一单元我们学习了虚拟语气中与现在、将来事实相反的虚拟条件句及宾语从句的虚拟语气。本单元要继续学习虚拟语气中与过去事实相反的虚拟条件句，及虚拟语气在其它从句中的应用。 首先，我们先看下面含虚拟语气的句子： 1. We would have won, if Jack had scored that goal. 2. We would have won if we hadn’t stayed up so late the night before. 3. We would have won the championship, if we had got Mr Han to coach us. 4. If she had studied harder, she would have got the diploma. 这些句子都是与过去事实相反的虚拟条件句。下面我们就来学习这部分内容。 用法讲解 与过去事实相反的虚拟条件句 虚拟条件句的动词形式 假设类型条件从句（if从句）谓语动词主句的谓语动词 与现在事实相反一般过去式(be用were) would/should/might/could +动词原形 与将来事实可能相反1）一般过去式(be只用were) 2）were to + 动词原形; 3）should + 动词原形 would/should/might/could+动词原形 与过去事实相反had done would/should/might/could + have过去分词 从表格可知，虚拟条件句与过去事实相反时，条件从句的谓语用过去完成时，而主句的谓语用would/should/might/could加现在完成时形式。 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---he didn’t take my advice） If you had come a few minutes earlier，you would have met him. 要是你早来几分钟的话，你就见到他了。（事实：来晚了---you came late） If She hadn’t been so strict with herself, she wouldn’t have made such great progress. 她要是对自己要求不严格，她就不会有这样大的进步。 （事实：她对自己很严格---she was strict with herself） 虚拟语气中的倒装 条件从句中的were，had, should可放句首，省略if，条件句成为倒装句。 Had you (If you had) invited us, we would have come to your party. 如果你邀请我们了，我们会参加你的聚会的。
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）
Section_ⅢGrammar—_虚拟语气(2) 语法图解 探究发现 ①If you had come earlier, you would not have missed the exciting scene in the movie. ②If you had told me the news yesterday, I wouldn't be so worried now. ③Had I left sooner, I would havebeen there on time. ④But for your advice, I would have failed. ⑤He treats the little girl as if she were his own daughter. ⑥It's high time that we began the work. ⑦It's necessary that we (should) learn English well. ⑧If only I had not been busy last week. [我的发现] (1)在表示与过去事实相反的虚拟语气时，条件句的谓语动词用“had＋过去分词”形式表示，而主句谓语动词则用“would/should/might/could＋have＋过去分词”表示。(如例句 ①) (2)当条件句的谓语中有had, were或should时，可将if省略，同时将had, were或should 提到从句主语的前面，形成倒装。(如例句③) (3)当主从句所指的时间不一致时，其谓语动词应分别根据自己的具体情况采用适当的形式。(如例句②) (4)有时某些介词短语、副词或上下文可以表示虚拟条件，这种虚拟语气叫含蓄条件句。(如例句④) (5)as if引导的从句所表达的内容不是事实时，其谓语动词应用虚拟语气。(如例句⑤) (6)虚拟语气还用于某些特殊句式(结构)中。(如例句⑥、⑦和⑧)
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：虚拟证据表示说的话不是事实，或者不可能发生的情况，而是一种愿望、建议或者与事实相反的假设等，一般常用于正式的书面语中。 一、虚拟语气在if条件从句中的用法： 1、a. If I were you, I would apply for the job. b. If I lived near my office, I would walk to the office. 与现在事实相反，If条件从句谓语：过去式（be用were） 主句谓语：should / would / could / might+动词原形 2、a. If you had been more careful, You could have passed the exam. b. If you had turned off the gas, the house wouldn’t have caught fire. 与过去事实相反，If条件从句谓语：had+动词过去分词 主句谓语：should / would / could / might + have done 3、a. If it should rain tomorrow, we would not go camping. b. if it were to rain tomorrow, we would not go camping. c. If it rained tomorrow, we would not go camping. 与将来事实相反：If条件从句谓语：过去式 / should + v原形 / were + to do 主句谓语：should / would / could / might + do 二、混合虚拟条件句：不同时间的虚拟，各遵守各的规则，如： a. If you had followed the doctor’s advice, you would be quite all right now. 从句叙述与过去事实相反（had + done），主句叙述与现在事实相反（would + v）
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.
高中英语虚拟语气总 结
虚拟条件句 Q: What’s the difference between the two sentences? If I am free, I will visit you. (______条件句) If I were a bird, I would fly into the sky.

虚拟语气（1） 编稿：牛新阁审稿：王春霞 概念引入 动词的语气表示说话人的态度和看法，可分为陈述语气、祈使语气和虚拟语气。 1. 陈述语气用来陈述事实或可能发生的事，有肯定、否定、疑问和感叹等形式。 Aileen showed great concern about you. 艾琳很为你担心。（肯定） My legs were so weak that I could hardly stand. 我的腿软得简直不能站立。（否定） Would you care to come and stay with me over the weekend? （疑问） 你愿意来和我过周末吗？ 2. 祈使语气用来提出请求、发出命令、警告、威胁、叮嘱、祝福、建议等。 Enjoy yourselves with your trip. 一路愉快。（叮嘱） Don’t let this type of things happen again. 别让这种事再次发生。（警告） 3. 虚拟语气是说话人为表达一种假设, 或一种主观愿望, 即认为动词所表示的动作或 状态并非真实或仅是主观设想时所用的动词形式。 我们先看这些含虚拟语气的句子： 1. If you were an artist, what kind of pictures would you paint? 2. If you could have three of these paintings on the walls of your classroom, which would you choose? 3. If the rules of perspective had not been discovered, no one would have been able to paint such realistic pictures. 4. Without the new paints and new technique, we would not be able to see the many great masterpieces for which this period is famous. 5. Have you ever wished you could paint as well as a professional artist? 本单元将重点学习if从句的虚拟语气和wish和“suggest”类后的宾语从句中的虚拟语气的用法。 用法讲解 if引导的虚拟条件句 1. 真实条件句与虚拟条件句： 条件句分成两种，一种是真实条件句，一种是非真实条件句。真实条件句用陈述语气，所做的假设，说话人认为是可以实现的，或者与事实相符的；而使用虚拟条件句时，说话人知道所做假设与事实不符，或者很可能无法实现的。如： If I have enough money, I will go to the zoo with you. 如果我有足够的钱，我会和你一起去动物园。（暗含“我看看钱是否够，如果够我就去”）If I had enough money, I would go to the zoo with you. 如果我有足够的钱，我会和你一起去动物园。 （暗含“我事实上没有足够的钱，没法和你去”）
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
