虚拟语气中的含蓄条件句常见用法总结
虚拟语气中的含蓄条件句常见用法 先看一道高考题： ____ more attention，the trees could have grown better． A．Given B．To give C．Giving D．Having given （答案是A） 句中"．．．the trees could have grown better"是一个表达虚拟语气的句子。题中要求选择的是如何表达假设条件的形式。如果我们把这个句子用另一种形式"If they had been given more attentio n ，the trees could have grown better．"来表示，就不难理解了。很多情况下，在表示假设的虚拟语气中，有时假设的条件并不以条件从句的形式表达，而是通过上下文或句中内在的逻辑关系，或用其它形式表达出来，我们称之为"含蓄条件句"。 含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。现分述如下： 一、介词短语 常用来表示虚拟条件的介词有with，without，in，under，but for等等，它们表示的虚拟条件都可以被if从句替换。 （1）without，with without表示否定的条件，意为if．．．not；with与without意义相反，表示肯定的条件。如：Without air，there would be no living things．（without air ＝if there were no air）没有空气，便没有生物。 With her help（＝If I had her help），I would do the experiment well．假如有她帮助，我就可以把这个实验做好。 （2）under Under the leadership of a less experienced person，the experiment would have failed．（u nder．．．＝If there had been the leadership of a less experienced person）假设在一个缺少经验的人领导下进行实验，实验准会失败。 （3）in I would have lost my head in that position．（in that position ＝if I had been in that po sition）我处在那种情况下，是会丧失理智的。 （4）but for
(完整版)虚拟语气的用法及专项练习题[1]
虚拟语气的用法及专项练习题 虚拟语气表示一种假设的情况，或一种主观的愿望，即动词所表示的动 作或状态并非事实，或不可能实现。英语虚拟语气的形式有下列几种： 一.虚拟语气用于条件状语从句 注意:主句中的should 通常用于第一人称,would 可用于任何人称,同时 也可根据意思用情态动词could,might 等代替should,would 。 If I were you, I would give up drinking immediately. country. 3.与将来事实相反 If it were to/should rain tomorrow,the meeting would be put off. If you went there next time, you would see what I mean. 4.错综时间虚拟语气 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,动 词的形式要根据它所表示的时间来调整。例如: If I were you, I would have gone home.
If you had followed the doctor's advice,you would be quite all right now.(从句说的是过去,主句指的是现在。) If the weather had been more favorable ,the crops would be growing still better. 状语从句 1. 方式状语as if(as though) 如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用"had+过去分词";表示与将来事实相反,谓语动词用"would(might,could)+动词原形"。例如: He looks at me as if I were mad. He spoke English so fluently as if he had studied English in England. 但as if(as though)后的从句也常用陈述语气,这是因为从句中的情况往往是可能发生的或可能被设想为真实的。例如: It looks as if our side is going to win. 2.目的状语in order that,so that 从句谓语动词用" may/might,can/could)+动词原形"。例如: She listened carefully in order that she might discover exactly what he wanted. 3. 连词引导的条件状语从句: in case , unless ,supposing ,providing,on condition that从句谓语动词用(should)或" might, could)+动词原形"。 4. 连词引导的步状语从句: lest ,for fear that等 We hid behind some bushes for fear that passer-by should see us. 二.虚拟语气用于宾语从句 注意：在此结构中that不可省略；should省不省均可。 He suggested that they (should ) stop smoking. They demanded that the black people should be treated as well as white people. 如果that 引导的从句所表达的内容是事实，也可用陈述语气。 He insists that he is right.
虚拟语气详解
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.

if条件句中的虚拟语气讲解
虚拟语气(一) 一、考点聚焦 1、虚拟语气用于条件状语从句中 If I were a boy, I would join the army. If she had time, she should go with you. If h e had taken my advice, he would have succeeded in the competition. If i t were to rain tomorrow, the football match would be put off. If I had time, I would attend the meeting. If he had hurried ,he could have caught the train. If I were to go abroad ,I would go to America 如果我是你，我就会努力学习 If I were you, I would work harder at my lessons. 如果我知道他的电话号码，我就给他打电话了 If I had known his telephone number, I would have called him. 如果明天下雨的话，我们会取消比赛． If it should \were to rain, we would call off the match.
使用虚拟条件句要注意的几点： 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． If you had studied hard before, you would be a college student now. 如果你努力学习的话，你现在就会是大学生了． If they had worked hard, they would be very tired now.(从句说的是过去，主句指的是现在) ２．省略句 在条件句中，可省略if，把were ,had, should 提到句首，变为倒装句式．If I were at school again, I would study harder. Were I at school again, I would study harder. If you had come earlier, you would have met him. Had you come earlier, you would have met him. If it should rain tomorrow, we would not go climbing. Should it rain tomorrow, we would not go climbing. Were I a boy, I would join the army. Had he taken my advice, he would have succeeded. Were it not for the expense, I would go to Britain. 2、虚拟语气用于名词性从句 （1）虚拟语气在宾语从句中的运用。 ①“wish + 宾语从句”表示不能实现的愿望，译为“要是……就好了”等。 表现在过去时 表过去过去完成时 表将来would, might, could＋动词原形 I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. I wish (that) I were a bird. I wish (that) I had seen the film last night. I wish (that) I would\could go.

A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。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。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I not so busy ,I with you . A．was , would go B．were , would go C．was , should go D．were , will go 【答案】B 【解析】句意“如果我不忙，我就跟你去”。本题考查对将来的虚拟语气。即“if+过去时，主语+should/would/could/might do”结构。故选B。 点睛： 3．If I ___ you, I ___ be afraid . A．was, wouldn’t B．were, won’t C．were, wouldn’t 【答案】C 【解析】 试题分析：根据语境可知此句的含义是如果我是你，我就不害怕。考查的是虚拟语气的基本用法。条件用过去时，主句要用过去将来时，故选C。 考点：虚拟语气 点评：虚拟语气其实就是if引导条件状语从句时，词义为“如果”，不过这个条件是无法实
if条件状语从句中虚拟语气
if条件状语从句中的虚拟语气 一、if条件状语从句中虚拟语气的判断判断是真实条件句还是非真实条件句。 只有在非真实条件句中才使用虚拟语气。通过句子意思，看假设的条件是否能够实现， 能够实现是真实条件句，不能使用虚拟语气； 假设的条件不能实现则是非真实条件句，要用虚拟语气。 1. “后退一步法”后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就是： ①与过去事实相反，在从句中用过去完成时形式表示。 ②与现在事实相反，在从句中用过去一般时形式表示。 ③与将来事实可能相反，在从句中用过去将来时形式表示。主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。 例：⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my students. ⑶、If it should snow tomorrow, they couldn't go out. 2、注意事项： ①if条件句中如有were, should, had，可以省去if，并使用倒装语序。 ②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。 二、虚拟语气在if 引导的条件句中的用法： 1. If it weren’t for your help, we would get into trouble. 如果没有你们的帮助，我们就会陷入困境。（而事实上得到了你们的帮助） 2.If the weather were fine, I would go there. 如果天气好，我去那儿。（事实天气不好） 3.If I were you, I would read it again. 如果我是你的话，我再读一遍。（事实上我不是你） 4.If time permitted, I would write it again. 如果时间允许的话，我再写一遍。（事实上时间不允许） 5.If it weren’t snowing, we wouldn’t stay in the house. 要是现在不下雪的话，我们就不会待在屋里。（事实上现在下雪） 6.What would I do if I were in your place?要是我处于你地位我会怎么办？（事实上我不在你的位置上） 7.If he hurried, he could catch the first bus. 他要是快点能够赶上头班公共汽车。（可是他不着急） 8. If I were you, I should buy it. (从句用过去式动词were，主句用动词原形buy) 9. If I had time, I would study French. (如果有时间，我会学习法文。)（从句用过去式动词had，主句用动词原形study） 10. If she knew English, she would not ask me for help. (如果她懂英文，她就不必要我帮了。)(从句用过去式动词knew, 主句用动词原形ask) 注意：如果动作在进行中，主句要用："主语+ would be + 进行式动词+ ……" 14. If they were here, he would be speaking to them now. (从句用过去式动词were, 主句用would be speaking)

复习专题虚拟语气专项练习题及答案 一、初中英语虚拟语气 1．–I argued with my best friend. What should I do? --If I ________ you, I would say sorry to her. A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。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。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I you, I give it to Microsoft research. A．am, will B．am, would C．were, would D．was, would 【答案】C 【解析】 【详解】 句意：如果我是你，我会把它交给微软研究部。 考查虚拟语气。根据If I you，这是一个虚拟语气，此句虚拟语气表示一种不能实现的假设，即与现在事实相反，谓语动词用过去式；该语法主要用于if条件状语从句，本句“如果我是你”，be动词用were，后面主句用过去将来时would＋动词原形，故答案选C。 3．I suggest that we Chinese people_______Chinese culture with love and joy everywhere we go. A．spread B．spreading C．to spread D．will spread 【答案】A 【解析】 【详解】 句意：我建议我们中国人无论走到哪里都要带着爱心和欢乐来传播中国文化， 考查动词suggest后跟虚拟语气。spread是动词原形；spreading是动名词；to spread是动词不定式；will spread是一般将来时。动词在这里suggest表示建议，后面宾语从句中使用虚拟语气should+动词原形，should可以省略。根据句意说明本句的suggest表示建议，故后面使用虚拟语气，省略了should，故选A。 【点睛】 动词suggest 后面可以跟名词作宾语，用于句型“suggest sth.”。如：I suggested a visit. 我提议参观。 suggest 后跟动名词作宾语，如：He suggested going home. 他提议回家。 suggest后面跟that引导的宾语从句时，用虚拟语气，一般省略情态动词should，所以本题选项是A。
(完整版)if引导的条件句中的虚拟语气
if引导的条件句中的虚拟语气 虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。 一、if引导的条件状语从句的分类及虚拟条件句的判断 1、可以把条件句分为两类： 1).真实条件句（Sentences of Real Condition）：凡是假设的情况发生性可能很大，就是真实条件句。例如： ⑴、If I have time , I will help you with this work.如果我有时间会帮助你做此工作的。 (2)、If time permits, we'll go fishing together.(如果有时间的话，我们就一起去钓鱼。） 2).虚拟条件句（Sentences of Unreal Condition）：当假设是不大可能实现时，就是虚拟条件句。例如： ⑴、If I were you , I would have attended the meeting. 如果我是你的话，就去参加会议了。 ⑵、If he had come here yesterday, he would have seen his ol d friend.假如他昨天来这儿的话，就会看见他的老朋友。 ⑴、If it had rained yesterday, we would have stayed at home.（如果昨天下雨的话，我们就会留在家里。） 2、.if条件状语从句中虚拟语气的判断 判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思，看假设的条件是否能够实现，能
够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。 判断这个假设是与哪个事实相反。通常有三种情况：①与过去事实相反。②与现在事实相反。③与将来事实可能相反。 3、“后退一步法” 后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就是： ①与过去事实相反，在从句中用过去完成时形式表示。 ②与现在事实相反，在从句中用过去一般时形式表示。 ③与将来事实可能相反，在从句中用过去将来时形式表示。 主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。例： ⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my students. ⑶、If it should snow tomorrow, they couldn't go out. 4、注意事项 ①if条件句中如有were, should, had，可以省去if，并使用倒装语序。 ②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
初中虚拟语气讲解及专项练习与答案(带解析)
虚拟语气讲解 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。 直陈语气(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、建议或与事实相反的假设等。 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。）

if可以引导真实条件句和虚拟条件句
Unit 4 一. if 条件句 if可以引导真实条件句和虚拟条件句。真实条件句表示在假设的条件下，能够实现的情况。在这种情况下，主句和从句的谓语动语随各自的人称和时态发生变化，同时if条件句遵循“主将从现”的原则，即主句用一般将来时，从句用一般现在时表将来。 If it doesn’t rain tomorrow, we will go for a picnic. 如果明天不下雨，我们去野餐。 如果if条件句用来描述说话人认为与事实相反的内容，或仅是一种愿望，假设、猜测等，我们称为虚拟条件句。 If I got rich , I would travel around the world. 如果我有钱了，我将周游全世界。 1. —I often get nervous when I have an English class.
