高考英语复习知识点：情态动词和虚拟语气及英语作文结尾万能公式
高考英语复习知识点：情态动词和虚拟语气及英语作文结尾万能公式高考英语复习知识点：情态动词和虚拟语气虚拟语气在高考命题中不是重点，但是难点。
考点常集中在含蓄条件句以及主语、宾语从句等特定句型中虚拟语气的使用上，因此考生应熟练掌握含蓄条件句中主从句的时态要求以及一些典型句型中虚拟语气的具体形式。
虚拟语气考点透析考点一、虚拟语气的基本用法1.与现在事实相反的虚拟语气，基本结构为：主语+动词的一般过去时(be动词用were)+其他成分+if+should/would/could...+动词原形+其他成分。
例如：①If it were not for the fact that she ______ sing，I would invite her to the party.A.couldntB.shouldntC.cantD.might not解析句意为：如果不是因为她不会唱歌的事实，我会邀请她来参加那次聚会的。
that从句为同位语从句，描述的是事实，用陈述语气。
正确答案为C。
2.与过去事实相反的虚拟语气，基本结构为：主语+动词的过去完成时+其他成分+if+should/would/could...+have done+其他成分。
例如：If the weather had been better，we could have had a picnic.But it ______ all day.A.rainedB.rainsC.has rainedD.is raining解析句意为：如果天气好的话，我们是能够去野餐的，但是下了一天的雨。
句子前半部分陈述的是与过去事实相反的事情，所以用了虚拟语气。
下了一天的雨是事实，所以用陈述语气。
因为是发生在过去的事实，所以正确答案为A。
3.与将来事实相反的虚拟语气，基本结构为：主语+动词的一般过去时/should do/were to do+其他成分+if+should/would/could...+动词原形+其他成分。
