英语中的虚拟语态是什么?怎么用?

虚拟语态 一、虚拟语态的几种固定句式1.I wish.(一定用虚拟) 1）I wish i were you2)I wish that she were here with me2、as if./as though 好象 (不一定用虚拟,要看说话的语境``)1）He speaks as if he were an American.(如果他真的是美国人就不用虚拟了`)2）He looks as if nothing had happened.3、if I did/were.I would.1)If I were you,I wouldn't do that2)If it were to snow tomorrow,they would not go out.(用were to 和were的区别是were to 是对将来的虚拟,用were是对现在的虚拟`详见二、虚拟语态的几种形式```) 二、虚拟语态的几种形式1、对现在的虚拟：（直接用动词的过去时.） if I did /were.i would.2、对将来的虚拟：if ..were to..I would.= if ..did...I would.(此项与对现在的虚拟相同,但对现在的虚拟不用were to.要区别对将来的虚拟和对现在的虚拟``一般句子里面都有时间标志``)(If it were to rain tomorrow,we would not go out.=If it rained tomorow,we would not go out.)3、对过去的虚拟 If I had done.I would have done.(If I had know the answer,I would have told you.)(至于If ..had been done ...would have done 前面的been只是因为是被动语态```所以要看句子的具体意思````)另外..固定句型的补充..要用虚拟语态的句子:i would rather i could.(I would rather she could not come here)if noly..(但愿.)A:I will go to Korean next month.B:If only I could go with you======以下答案可供参考======供参考答案1:虚拟语态表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设，推测，命令，建议，要求等。o(∩_∩)o...三种基本结构：1. 与现在事实相反的假设：一般过去时（be用were)，主句结构{ should(would)等+动词原型}例如：If they were here ,they would help you.如果他们在这，会帮助你的。2. 与过去事实相反的假设：过去完成时 主句结构：{should(would)等+have+过去分词}例如：If he had come yesterday,i should(would)have told him about it.如果他昨天来的话，我会把这件事告诉他的。3. 表示对将来不大发生的是的假想。一般过去时，were+不定式，should+动词原形；主句结构：{should(would)+动词原形。例如：If you succeeded ,everything would be all right.如果你将来成功了一切都会好的。(*^__^*)
