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。

初中英语知识点总结虚拟语气7篇

初中英语知识点总结虚拟语气7篇篇1虚拟语气是英语语法中的一个重要内容,它主要用于表达与事实或现实不符的情况,或者用于表达一种假设、条件或非真实的情况。

在初中英语学习中,掌握虚拟语气的用法对于提高语言表达能力和写作水平具有重要意义。

一、虚拟语气的构成虚拟语气分为三种形式:虚拟现在时、虚拟过去时和虚拟将来时。

每种形式又可分为简单式、进行式、完成式等。

虚拟语气的构成主要涉及动词原形、动词过去分词和动词现在分词的变化。

掌握这些变化形式是正确使用虚拟语气的关键。

二、虚拟语气的用法1. 条件状语从句中的虚拟语气在表示与事实相反或不太可能发生的条件状语从句中,需要使用虚拟语气。

例如:If I were you, I would study harder.(如果我是你,我会更加努力学习。

)这个句子表达了与事实相反的条件,因此使用了虚拟语气。

2. 宾语从句中的虚拟语气在表示请求、建议、命令等动词后面的宾语从句中,也需要使用虚拟语气。

例如:She suggested that we should start early.(她建议我们早点出发。

)在这个句子中,suggest后面的宾语从句使用了虚拟语气。

3. 主语从句中的虚拟语气在表示惊讶、遗憾、后悔等情绪的主语从句中,可以使用虚拟语气来表达这些情绪。

例如:What a pity it is that he missed the chance!(真遗憾,他错过了这个机会!)这个句子中的主语从句使用了虚拟语气来表达遗憾的情绪。

三、虚拟语气的应用场景1. 表达假设或条件虚拟语气可以用于表达假设或条件,例如在写作文时,可以使用虚拟语气来描述一个假设的场景或条件,以引出自己的观点或论点。

例如:“If I were a bird, I would fly to the sky and look at the world from above.”(如果我是一只鸟,我会飞到天上,从高处俯瞰世界。
