英语高考虚拟语气专项练习60题(附答案)
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的虚拟语气如果从句中含有were/ should/ had时，则可以把这三个词置于句首，省略if.采用倒装语序。

复习专题虚拟语气专项练习题一、初中英语虚拟语气1．If I ____ a candle, I would light the world bright.A．am B．are C．be D．were【答案】D【解析】试题分析：句意：如果我是一根蜡烛，我将点亮这个世界。
if I were 如果我是…，were虚拟语气，be动词都用were,故选D考点：if条件句的虚拟语气点评：if条件句的虚拟语气，是中考要求掌握的知识点，分为三种情况：表示与现在事实相反的情况，从句谓语动词用一般过去式（be用were），主句谓语动词用should/would/could/might +do;2.表示与过去的事实相反的情况，从句谓语动词用过去完成时，主句谓语动词用should/would/could/might+have done;3.表将来的事实相反的情况，从句谓语动词用should+动词/did/were to do，主句谓语动词用should/would/could/might+do。
2．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现的。
从句中的谓语动词通常用一般过去时表示，则主句中的谓语动词用过去将来时。
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。
4．She doesn’t stick to her exercises and a balanced diet. If she _______, she would remain slim and healthy.A．had done B．would do C．did D．should【答案】C【解析】【详解】句意：她没有坚持锻炼和均衡饮食。
如果她这样做了，她将保持苗条和健康。
考查虚拟语气。
had done过去完成时；would do过去将来时；did过去时；should应该；根据后文“would remain ”，所以是对现在的虚拟，此处应是did/be动词（were），故选C。
5．You _______ through that red light, for you _______ an accident.A．must have driven; should have caused B．could have driven; might have caused C．couldn’t have driven; should have caused D．shouldn’t have driven; could have caused 【答案】D【解析】【详解】句意：你不应该开车闯红灯，因为你会引起事故的。
考查情态动词。
分析句子及选项“You ___ through that red light, for you ____ an accident.”，你开车闯红灯，因为你事故的，可知是对过去的虚拟，应用情态动词+have done。
此处是不应该开车闯红灯，会引起事故，故选D。
6．Yesterday, the storm delayed us. _______ the storm, we would have been here in time. A．But for B．If it were not for C．But that D．Unless【答案】A【解析】【详解】句意：昨天暴风雨耽搁了我们。
要不是有暴风雨，我们会及时赶到这里的。
考查连词。
But for要不是+短语；If it were not for要不是（用于对现在的虚拟）；But that 要不是+从句；Unless除非,后接条件状语从句；根据句中是“the storm”，是名词，所以排除C；根据“would have been ”，是对过去的虚拟排除选项B；分析句子“___ the storm, we would have been here in time.”有暴风雨，我们会及时赶到这里的，应该是“要不是”，故选A。

11． If I went to the moon, I ______ bring something unusual back to the earth.A．couldB．willC．would【答案】C【解析】试题分析：此题考查if引导的条件状语从句的相关知识。
根据语境可知此句的含义是如果我去月球，我会带回一些不同寻常的东西。
这个假设成立的几率很小，故看为虚拟语气。
根据语法知识可知从句要用一般过去时，主句要用过去将来时，过去将来时的基本构成would+动词原形，故选C。
考点：if引导的条件状语从句点评：if既可以引导宾语从句又可以引导状语从句。
if充当宾语从句的连接词时，相当于whether，词义为“是否”，遵循宾语从句的时态规则，可根据语境选择任何时态；充当从属连词，引导条件状语从句时，词义为“如果”，若主句中的谓语动词用一般将来时，则从句中的谓语动词通常用一般现在时表示将来。

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。
1、与现在事实相反若与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”2、与过去事实相反若与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用“should （would, could, might）+have+过去分词”3、与将来事实相反若与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”。
