虚拟语气专项练习(附答案)
【答案】A
【解析】
试题分析：句意：我班里的一个学生对我说：如果我是数学老师，我会使数学学习更简单有趣，而不是每天给学生许多作业去做。虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。其主要有三种结构：
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”
考点：考查虚拟语气的用法。
11．If Iyou, Ithe army.
A．am, would joinB．were, would joinC．am, will joinD．were, will join
【答案】B
【解析】
试题分析：句意:如果我是你,我会参军.结合语境可知本句是对客观状况的虚拟,故用过去时态,主句用过去将来时态.选B.
--- If I______ you, I would try to find some information about it on the Internet.
A．amB．wasC．will beD．were
【答案】D
【解析】
试题分析：句意：——倘若我必须去那儿而且对那里一无所知，该怎么办？——如果我是你，我会在网上查找一些有关那里的信息。根据I would try to find可知主句用的是would+do,可知这是对现在事实的假设的虚拟语气，因此If引导的条件状语从句用一般过去时，根据虚拟语气的用法be动词在If引导虚拟语气中用were .故选D。

2．--------- Come and join us, Jim!---------- I’m sorry I can’t . If I _______ time, I would certainly go.A．will have B．have had C．had D．had had【答案】C【解析】试题分析：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。
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”：句意：吉姆，来加入我们吧！抱歉，我不能。
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。

句意：空气污染越来越糟糕。政府建议人们乘地铁或者乘公交车去上班。
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。
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”
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。
A．amB．wasC．will beD．were
【答案】D
【解析】
试题分析：句意：——倘若我必须去那儿而且对那里一无所知，该怎么办？——如果我是你，我会在网上查找一些有关那里的信息。根据I would try to find可知主句用的是would+do,可知这是对现在事实的假设的虚拟语气，因此If引导的条件状语从句用一般过去时，根据虚拟语气的用法be动词在If引导虚拟语气中用were .故选D。
考点：考查虚拟语气。
2．If Iyou, Igive it to Microsoft research.
A．am, willB．am, wouldC．were, wouldD．was, would

考点：if引导的条件状语从句
点评：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。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。
