高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 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并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

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。
虚拟语气有三种情况：1.表示与现在事实相反或不可能发生。
条件状语从句用一般过去时（虚拟语气中be→were），主句用would(should。
could。
might)+动词原形。
例如：If we had time now。
wewould 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。
条件状语从句用had+过去分词，主句用would(should,could。
might)+have+过去分词。
例如：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。
条件状语从句用①一般过去时②should +动词原形③were to+动词原形，主句用would(should。
could。
might)+动词原形。
例如：If it should rain。
the crops would be saved。
If it were to snow tomorrow。
they would not go out.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。
例如：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。

中考英语虚拟语气顶级综合用法练习题30题(带答案)1. If I ____ a bird, I would fly to every corner of the world.A. amB. wasC. wereD. be答案：C。
解析：这是一个与现在事实相反的虚拟语气句子。
在虚拟语气中，be动词在条件句中不管主语是什么人称，都要用were。
A选项am是一般现在时的用法，不符合虚拟语气结构；B选项was 虽然是be的过去式，但在虚拟语气中这种用法错误；D选项be形式错误。
2. If Tom ____ more carefully in the exam yesterday, he ____ better results.A. had written; would getB. wrote; would have gotC. had written; would have gotD. writes; will get答案：C。
解析：本题考查与过去事实相反的虚拟语气。
句子中有明显的yesterday表明是过去的事情。
在这种情况下，条件句要用had + 过去分词，主句要用would + have + 过去分词。
A选项主句结构错误；B选项条件句结构错误；D选项是一般现在时和一般将来时的结构，不符合虚拟语气要求。
3. If it ____ rain tomorrow, we would go camping.A. doesn'tB. didn'tC. won'tD. wouldn't答案：B。
解析：这是一个与将来事实相反的虚拟语气句子。
在这种情况下，条件句可以用should + 动词原形、were to + 动词原形或者一般过去时。
这里用一般过去时表示将来不太可能发生的假设。
A选项是一般现在时的否定形式，不符合；C选项是一般将来时的否定形式，错误；D选项是过去将来时，结构错误。
（完整版）虚拟语⽓的⽤法及经典练习题（附答案）虚拟语⽓概念虚拟语⽓⽤来表⽰说话⼈的主观愿望或假想，⽽不表⽰客观存在的事实，所说的是⼀个条件，不⼀定是事实，或与事实相反。
虚拟语⽓通过谓语动词的特殊形式来表⽰。
英语中的语⽓分为陈述语⽓、祈使语⽓、虚拟语⽓三类。
应⽤条件在表⽰虚假的、与事实相反的或难以实现的情况时⽤虚拟语⽓，表⽰主观愿望或某种强烈情感时，也⽤虚拟语⽓。
即当⼀个⼈说话时欲强调其所说的话是基于⾃⼰的主观想法，⽽不是根据客观实际，就⽤虚拟语⽓。
在⾮真实条件状语从句中的⽤法真实条件状语从句与⾮真实条件状语从句条件句可分为两类，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或实际可能性不⼤的情况，故采⽤虚拟语⽓。
例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴⼠。
( 真实) If he is free, he will ask me to tell stories. 如果他是空闲的，他会要求我讲故事。
（真实）If I were you, I would go at once.如果我是你，我马上就会去。
（⾮真实，虚拟语⽓）If there were no air, people would die. 如果没有空⽓，⼈就会死亡。
（⾮真实，虚拟语⽓）⽤法及动词形式例句：1、表⽰与现在事实相反的情况：例： 1. 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） 2.If I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。
（事实：不知道） 3.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。

如：If he had taken my advice, he would have succeeded in the competition.（3）表示与将来事实相反，条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形，而主句中的谓语动词则用would / should/could might + 动词原形。
如；If it were to rain tomorrow, the football match would be put off.（4）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作相应调整。
如：If they had worked hard, they would be very tired.(从句说的是过去，主句指的是现在)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。

三大从句及虚拟语气综合练习一、单句语法填空1．Life is like a long race ________ we compete with others to go beyond ourselves.解析：where [先行词为race，代入定语从句则为：we compete with others to go beyond ourselves in the long race.明显可见，in the long race在定语从句中作地点状语，故填where。
]2．Tom's best memory is of last year，________ the club gave a dancing party for his birthday.解析：when [先行词是last year，带入从句后作时间状语，故从句用关系副词引导。
] 3．Recently，we have seen the film you mentioned，the figures of ________ are used in many restaurants to attract consumers.解析：which [根据句意可推知从句想表达“此影片的许多人物被多家餐厅引用来吸引消费者”。
先行词为the film，指物，且空处位于介词of后，故填which引导非限制性定语从句。
]4．On Sundays there were many children playing in the park, ________ parents were seated together joking.解析：whose [本空填whose，引导非限制性定语从句并在从句中作定语。
]5．This is Mr.Smith，________ I think has something interesting to tell you.解析：who [非限制性定语从句修饰前面指人的先行词Mr.Smith，且定语从句中缺少主语，故用who引导。
]6．At the beginning of the new term，my teacher said ________ broke the rules would be punished.解析：whoever [这里whoever引导宾语从句，在从句中作主语，意为“无论是谁”。
] 7．I am afraid she's more of a talker than a doer，which is ________ she never finishes anything.解析：why [which引导非限制性定语从句，其中“...she never finishes anything.”为表语从句，且表原因，故此表语从句用why引导。
]8．It is obvious to the refugees ________ they should get well prepared to evacuate.解析：that [本句中it是形式主语，真正的主语是后面由that引导的从句。
]9．The mystery is ________ he ever went there or not.解析：whether [is后的表语从句中成分齐全，空格处意为“是否”，且由句末的or not可知用whether。
]10．I have no idea ________ you're talking about—can you explain it please?解析：what [idea后为同位语从句，该从句中的talking about后缺少宾语，且意为“……的事情”，故用what引导。
]11．(2019·江苏镇江模拟)We thought that, we were in the area, we'dstop by and see the places of interest.since[句意：我们认为，既然到这了，我们不如驻足一会儿，看一看这儿的名胜。
由句意可知，此处填since表示“既然”。
]12．(2019·哈六中模拟)However, when I had to go back I forgot my book, I noticed she had just finished picking them up by herself.because/since/as[根据句意并结合前后两句的逻辑关系可知，此处需用一个表原因的连词，故填because/since/as。
]13．(2019·北京西城模拟) I get home late，Grandma always leaves alight on for me.Whenever[whenever “无论何时”；根据句意，“每当”我回家晚了，故填Whenever。
]14．(2019·天津模拟)—Don't look down upon Bob. He has his own advantages.—Oh, yes, others are weak, he is strong.where[where可以引导表示抽象意义的地点状语从句。

故填where。
]15．(2019·江苏南通月考) serious a problem you may have, you shouldgather your courage to face the challenge.However[由句义判断此处表述“无论多么严重”。
故填However，引导让步状语从句。
]16．(2019·杭州质检)Remember that you won't be able to cancel the order you've signed.once[句意：记住一旦你签了字，就不能取消订单。
根据句义可知，此处表示条件，故填once。

结合句义可知，此处填while表“转折和对照”。
]18. (2018河南中原名校五次联考)Around 7:30 a.m., she was lying on her surfboardwith her left arm in the water a 14-foot-long tiger shark attacked her, severing her left arm just below the shoulder.答案when [句意:大约在上午七点半左右,她正躺在她的冲浪板上,左臂放在水里,就在那时一条14英尺长的虎鲨袭击了她,咬断了她肩部以下的左臂。
be doing sth. when...为固定句型,意为“正在做某事,这/那时突然……”。
]19. If you miss this chance, it may be years you get another one.答案before [句意:如果你错过了这次机会的话,那可能要等到多年之后你才能再次获得机会。
此处为固定句式it be+一段时间+before...。

whatever引导让步状语从句,相当于no matter what,意为“无论什么……”。
]21.
