英语语法 虚拟语气的知识点归纳
英语语法虚拟语气的知识点归纳一、虚拟条件句(一)含有if条件句的主从句的虚拟语气总结：1. If 条件句中谓语动词的虚拟结构是在原来陈述语气所用时态的基础上倒退一个时态（对将来虚拟的were to do/should do例外）2. 主句要借助于情态动词的过去式，后跟动词原形（现在或将来）或have done(过去)；if条件句中只出现一个情态动词，即对将来虚拟的should.3.做此类题目时一定要分清是从句还是主句谓语动词的虚拟，还要把握好时态。
注意：1. 在虚拟条件从句中，动词“be”的过去时态一律用”were”，不用was。
2. 在虚拟条件状语中如果有were, should, had这三个词中任何一个，可省略if，把这三个词提到主语之前, 变成：were/should/had +主语+剩余成分。
3.在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。
如我们可说Were I not to do., 而不能说Weren‘t I to do。
4.在表示与将来事实相反的条件句中，只能用should，而不能用would，could和might 等。
5.主句中的should通常用于第一人称，would，could以及might 可以用于各种人称eg :①If I were a bird, I could fly in the air.如果我是一只小鸟，我就能在空中飞行。
②I wish I could pass the examination.我希望我能通过考试。
在虚拟条件句中，对于与将来事实相反的情形，请注意以下几点：（1）条件从句表示的内容与将来事实相反，实为对将来情况的推测，用过去时表示虚拟；（2）条件从句谓语除用过去式外，有时也用“should+动词原形(表示可能性极小，常译为“万一”)”或“were to+动词原形(表示与将来事实相反的假设)”；（3）条件从句使用“should+动词原形”这样的谓语形式时，主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气形式外，也可用直陈语气或祈使语气。

它在表达与现实相反的情况、假设、建议和愿望等方面起到了重要作用。
本文将详细介绍虚拟语气的用法及常见表达方式。
一、虚拟语气的基本形式在英语中，虚拟语气的基本形式包括虚拟条件句和虚拟语气在从句中的使用。
1. 虚拟条件句虚拟条件句通常包括三个主要部分：if引导的条件从句、主句中的would/should/could/might以及从句中的动词形式（常为过去式或were）。
例如：- If I had more money, I would travel around the world.（如果我有更多的钱，我会周游世界。

高中英语虚拟语气讲解及练习
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。

高中英语虚拟语气的十大句型
高中英语虚拟语气的十大句型虚拟条件句：条件状语从句是非真实情况，在这种情况下要用虚拟语气。
1．条件从句与现在事实不一致，其句型为：句型1：If ＋主语＋过去时，主语＋should (could, would, 或might) ＋动词原形(1) If I were you, I would study hard.(2) If it rained, I would not be here now.2．条件从句与过去事实不一致，其句型为：句型2：If ＋主语＋had＋过去分词，主语＋should（could, would, 或might）＋have ＋过去分词(3) If the doctor had come last night, the boy would have been saved.(4) If I had not studied hard, I would have failed in the exam last term. 3．条件从句与将来事实不一致，其句型为：句型3：If ＋主语＋过去时/ should ＋动词原形/ were to＋动词原形，主语＋should (could, would, 或might) ＋动词原形(5) If it should rain tomorrow, we would stay at home.(6) If I were to go to the moon one day, I could see it with my own eyes.(7) If you missed the film tonight, you would feel sorry.注意问题：1．If条件句中绝对不可以出现would。
2．根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都要遵守上述句型。
如：(8) If you had studied hard before, you would be a college student now and you would graduate from a college in four years’time.3．条件句中如果出现were, had, should可省去if，将主语与这些词倒装。

掌握虚拟语气的用法能够帮助我们更准确地表达自己的意思。
