   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 you 2)I wish that she were here with me 2、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 that 2)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````) 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 only。
  。(但愿。。。。) A:I will go to Korean next month。B:If only I could go with you 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。
   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。 。收起
