IF的虚拟语气有三种：
与现在事实相反：动词过去式（be用were）——would/could/should/might+动原
If i were you, I would/could/should/might do that.
与过去事实相反：had+动词过去分词——would/could/should/might+have+动分
If i had know that yesterday, I would/could/should/might have told you.
与将来事实相反：should/were to+动原——would/could/should/might+动原
If it should rain, the crops would/could/might be saved.
