高考虚拟语气用法归纳
高考虚拟语气用法归纳咱先来说说这虚拟语气啊,对于要高考的同学们来说,那可真是个有点头疼但又特别重要的知识点。
虚拟语气这玩意儿,简单来说,就是假设一些不太真实或者没发生的情况。
比如说,“要是我当时好好学习,现在就不会这么发愁了”,这就是一种虚拟语气的表达。
咱们先瞅瞅条件状语从句中的虚拟语气。
要是与现在事实相反,从句就得用“if +主语+动词过去式(be 动词用 were)”,主句呢,就得用“主语+ would/could/should/might +动词原形”。
就像有个同学跟我抱怨,说:“老师,要是我现在有超能力,一下子就能记住所有单词,那英语考试就不愁啦!”这就是假设了一个现在不可能有的情况。
再说说与过去事实相反的情况。
从句得是“if +主语+ had +过去分词”,主句就得变成“主语+ would/could/should/might + have +过去分词”。
我记得有一次,一个同学考完试后懊悔地说:“哎呀,要是我考试前多做几道数学题,这次就不会错那么多了!”这就是在后悔过去没做的事儿。
还有和将来事实相反的,从句可以是“if +主语+ were to +动词原形;if +主语+ should +动词原形”,主句依然是“主语+would/could/should/might +动词原形”。
想象一下,有同学说:“要是明天世界末日,今天我就啥也不学,尽情玩!”虽然这事儿不太可能,但就是这种假设的虚拟语气。
虚拟语气在宾语从句里也有讲究。
比如说,wish 后的宾语从句,与现在事实相反用一般过去时;与过去事实相反用过去完成时;与将来事实相反用 would/could +动词原形。
我曾经听到一个同学许愿说:“真希望我现在是个学霸,啥题都会做!”这就是典型的与现在事实相反的虚拟语气表达。
还有在主语从句中,“It is +形容词(或过去分词)+that”结构中,如果形容词或过去分词表示“建议、要求、命令”等,从句的谓语动词要用“should +动词原形”,should 可以省略。

2025届高考英语语法复习虚拟语气知识讲解讲义
高考英语语法复习虚拟语气知识讲解一、基础知识(一)什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设(情感),也是一种语气(mood)的表现形式,表明说话的目的和意图。
(语气包含陈述语气、祈使语气、虚拟语气、疑问语气)虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况,即与真实相反。
上学的时候老师经常举的一个例子,"If I were you"因为我不可能是你,这是一种不可能存在的事实,所以这是个虚拟语句。
总而言之英语中的虚拟语气可以分为两大体系:一是表示与事实相反的,或者是假象的情形,通常由if引导,叫做虚拟条件句;另一个体系是在名词从句中使用虚拟语气,表示建议,命令或者要求等语气,类似于上述美剧常用的台词。
(二)虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解不同情况条件从句谓语主句谓语使用场景与过去事实相反If+主语+haddone主语+should/would/could/might+have done既然是过去了,那么谈到的一切情况都已既成事实,所以过去虚拟表达的是一个与过去事实相反的情形与现在事实相反If+主语+did(be动词用were)主语+should/would/could/might+do既可能是事实,也可能是假设条件。
因此,假设条件句和事实相反句适用于谈现在的情况与将来事实相反If+主语+ did(be动词用were)If+主语+ wereto + doIf+主语+should+ do主语+should/would/could/might+do对于将来时间的虚拟不可能以事实为基础,而只能是表达说话人的一个设想或愿望。
所以,对于将来的虚拟只适用于假设条件句,而不可能表达一个与事实相反的虚拟与现在事实相反:If I had a map, I would lend it to you.如果我有地图我就借给你。
(但我没有)与将来事实相反:If I were to do the job, I would do it in a different way. 要是我来做这工作,我会是另一种做法。
