虚拟语气倒装的三种情况 if的虚拟条件句中，如果含有were，should，had等动词时，省略if并将were，should，had等词移到句首：这就是虚拟条件句的倒装。 虚拟条件句中含有had 例如： If he had come yesterday，he would have know it. =Had he come yesterday，he would have known it. 虚拟条件句中含有were 例如： If I were there，I would help them. =Were I there，I would help them. 虚拟条件句中含有should 例如： If I should have 2000,000 yuan，I would buy a good car. =Should I have 2000,000 yuan,I would buy a good car. 虚拟语气定义 虚拟语气主要用来表示假设，而非客观存在的事实，所陈述的是一个条件，不一定是事实，甚至完全与事实相反。虚拟语气通过谓语动词的特殊形式来表示。此外如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。 本文来源：https://www.wddqw.com/doc/8d9cb3201411cc7931b765ce05087632311274b2.html
