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。
