虚拟条件句练习
虚拟条件句
在英语中，语气是动词的一种形式，用来表示说话人的意图或态度。
英语的语气有三种：_____语气（表示所说的话是事实），
_____语气（表示所说的话是请求或命令）
_____语气（表示所说的话只是一种主观的愿望或假设或建议等）。
如果所表示的条件是真实的，或者完全有可能实现的，叫真实条件句，主句和从句的谓语都用陈述语气。如果所表示的条件不可能实现或者实现的可能性很小时，叫非真实条件句，主句和从句的谓语要用虚拟语气。

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

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.
真实条件句,虚拟语气.
当我们陈述了一个事实，而又不是很有把握，就可以在陈述句后加一个简短问句，称为反意疑问句。首先看以下例句：（1） You like calssical music, don't you? 你也喜欢古典音乐，对吗？(2 He lived in Vienna, too,didn't he? 他也住在维也纳，对吗？（3）Your parents can swim, can't they? 你父母会游泳，是吗？（4） Tony doesn't like classical music,does he? 托尼不喜欢古典音乐，对吗？（5） This music isn't very popular, is it? 这音乐并非十分流行，对吗？从以上句子可以看出，反意疑问句是由“助动词/ 系动词be（肯定或否定）+主语（代词）” 构成的。在反意疑问句的构成中要注意以下几点： 1.前面当陈述句如果是肯定的，反意疑问句就要用否定形式，如（1）、（2）、（3）；前面的陈述句如果是否定的，反意疑问句就要用肯定形式，如（4）、（5）； 2.反意疑问句的主语必须是代替前面主语的代词； 3.翻译疑问句的谓语动词在时态和人称上要与前面陈述句谓语动词保持一致。陈述句部分如果有标识否定意义的词，反意疑问句要用肯定式。如：They have never visited his home, have they? 他们从来没有到他家玩过，是吧？在回答反意疑问句时，要特别注意英、汉两种语言习惯的差别。试看下面当例句：——Mr Smith isn't American, is he? 史密斯先生不是美国人，对吧？——Oh yes, he is.不对，他是美国人。可以看出，在英语中，无论问题是怎样问的，只要答语的事实是肯定句，就要用YES；只要答语的事实是否定的，就要用NO. 编辑本段英语18种特殊的反意疑问句介绍 1.祈使句。祈使句后一般加上will you或won't you构成反意疑问句，用will you 多表示“请求”，用won't you 多表示提醒对方注意。例如：Look at the blackboard, will you/ won't you?看黑板，好吗？Let引导的祈使句有两种情况：1Let's...,后的反意疑问句用shall we或shan't we。例如：Let's go home, shall we/ shan't we? 回家吧，好吗？还可以用may I来表示征求对方的同意或许可。2Let us/me...后的反意疑问句用will you或won't you。例如： Let me have a try, will you/won't you? 让我试一试，行吗？ 2.感叹句。感叹句后加反意疑问句时，其反意疑问句需用be的一般现在时态的否定形式。例如：What fine weather, isn't it? 多好的天气啊，是吧？ 3. 当陈述部分谓语动词是need, dare, used to，且这些词被用作实义动词时，其反意疑问句需用do的适当形

If条件句和虚拟语气
If条件句和虚拟语气 if 条件句和虚拟语气 包含条件从句的句子叫条件句。条件句有两类：一类是真实条件句（First conditional）,一类是非真实条件句(Second Conditional)。如果假设的情况是有可能发生的，就是真实条件句；如果是纯属假设情况或是不可能发生或可能性不大的情况，则是非真实条件句。 1.真实条件句,可用if和unless引导 1）一个动作发生，另一动作随之发生 I’ll lend Peter the money if he needs it. If he has time, he will come. If he doesn’t come before 12 o’clock, we won’t wait for him. I shall go tomorrow unless it rains. I won’t go to her party unless I am invited. 2）表示命令、建议或请求,这时的if等于when If she telephones, let me know. Give my love to Lawrence if you see him. 3)will用于if从句中，不表示将来，而表示愿意或坚持的意思 If you will come this way, I’ll take you to the manager’s office. If you will get drunk every night, it’s not surprising you feel ill. 2. 非真实条件句
非真实条件句包括虚拟条件句和错综时间条件句 1）虚拟条件句分三类，其结构列表如下： If I become president, I’ll make all of my people live a happy life. (竞选总统的候选人这样说) If I became president, I’d make all of my people live a happy life. (一个小学生这样说) l 以下与现在事实相反 He wouldn’t feel so cold if he were indoors. I am sorry I am very busy just now. If I hade time, I would certainly go to the movie with you. l 以下与过去事实相反 If you had come here a little earlier, you would have met the pop star. I don’t know what would have happened if Jane hadn’t been able to speak Japanese. l 以下推测将来 If I were to do the work, I should do it in a different way. If it should rain again, what else could we do? 2) 错综时间条件句

复习专题虚拟语气专项练习题及答案
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。
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. What should I do?
—If I were you, I . (ask the English teacher for help) 2. —What would the earth be like if there ?(is no air or water on it) —It could be like the moon without any living things. 3. If it ,the crops would be saved. (is to rain tomorrow) 4. If we had found him earlier, we .(solve the problem more easily) 5. If I hadn’t been so busy, I .(take part in the party) 四、单选。 ( )1.

必修2 If真实条件句与虚拟条件句
If真实条件句与虚拟条件句 真实条件句与虚拟条件句 1.真实条件句 真实条件句是指主句中的某一动作或状态是在真实情况下或有可能实现的情形下发生的。在表示真实条件句的复合句中，表条件的状语从句和表结果的主句的谓语都用陈述语气。 * If you come back late, your mother will worry about you. 如果你回来晚了，你妈妈会担心的。（if引导真实条件句，主句用一般将来时，从句用一般现在时表将来） * If your suggestion is rejected, they will let you know. 如果你的建议遭到拒绝，他们会让你知道的。（if引导真实条件句，主句用一般将来时，从句用一般现在时表将来） 2.虚拟条件句 （1）虚拟条件句指的是与事实相反或不太可能实现的事。在表示非真实条件的复合句中，表示条件的状语从句和表示结果的主语的谓语动词要用虚拟语气。
* If I were you, I would focus my attention on looking after my elderly parents. 如果我是你，我会把注意力集中在照顾年迈的父母上。（if引导虚拟条件句，叙述与现在事实相反，主句谓语动词用would do,从句谓语动词用过去式，be用were） * If he had got up a little earier, he wouldn’t have been late. 如果他早一点起床，他就不会迟到了。（if引导虚拟条件句，叙述与过去事实相反，主句用谓语动词would have done,从句谓语动词用had done） * If he should come(were to come/came)tomorrow, I would treat him to dinner. 如果他明天来，我就请他吃饭。（if引导虚拟条件句，叙述与将来事实相反，主句谓语动词用would do,从句谓语动词有三种形式：should do, were to do, 过去式） 当条件状语从句表示的动作与主句表示的动作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，这种虚拟条件句称之为错综复杂虚拟条件句。往往是主句叙述与现在事实相反，谓语动词用would/should/might/could do,而从句叙述与过去事实相反，
(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。

虚拟条件句 在英语中，语气是动词的一种形式，用来表示说话人的意图或态度。 英语的语气有三种：_____语气（表示所说的话是事实）， _____语气（表示所说的话是请求或命令） _____语气（表示所说的话只是一种主观的愿望或假设或建议等）。 如果所表示的条件是真实的，或者完全有可能实现的，叫真实条件句，主句和从句的谓语都用陈述语气。如果所表示的条件不可能实现或者实现的可能性很小时，叫非真实条件句，主句和从句的谓语要用虚拟语气。 （ 练习： 1.If I _____(be) you, I __________(tell) them the truth. 如果我是你的话，我就会把真相告诉他们。 2.If I_____(get) the information, I__________(let) you know first. 如果我知道这个情况的话，我会第一个告诉你。 3.If we__________(have) enough money, we _______________(buy)the house. 如果我们有足够的钱的话，我们就买下那座房子了。 4.If she ______________(come), what _______________(say) to her? 万一她来了，我该怎么对她说呢？ 5.If you don’t hurry, you__________(be) late for school. （2）省略if的虚拟条件句 在虚拟条件句中，如果有were，had，或should，就可以省略if，把这些助动词放在句首。 练习：改写下面句子，省略句中if 1.If I were you, I would tell them the truth. 2.If we had had enough money, we would have bought the house. 3.If she should come, what should I say to her? 能力训练
英语：高考虚拟语气专项练习60题(附答案) (1)
一．虚拟语气用于条件状语从句中 1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。 If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生：条件状语从句：①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况 (1). 混合/错综型虚拟语气 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，称为‘错综条件句’，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.(从句说的是过去，主句是现在) If I were you, I would have taken his advice.(从句是现在，主句是过去) （2）省略if的虚拟语气

关于虚拟语气的完整用法 第一类 编辑 虚拟语气在条件句中的用法： 条件句有真实条件句和虚拟条件句两种。真实条件句所表示的假设是有可能发生的，此时主句不用虚拟语气；而虚拟条件句则表示一种假想，与事实相反或不大可能会发生，此时用虚拟语气。如： If I have time，I will go. 假若我有时间，我就去。（陈述语气） If I were you，I would go. 假若我是你，我就去。（虚拟语气） 时态类型主句谓语形式 条件句的谓语 形式 例句 与现在事实相反would/should/could/might+ V 原形 动词过去式d id *be 多用wer e 1.
