虚拟语气中,如何对过去事实进行虚拟?

感谢您关注智课网（SmartStudy）
对过去的虚拟,表示与过去的事实相反的假设时,条件状语从句的谓语动词用过去完成时,主句的谓语动词用would (should,could,might)+过去分词.
条件状语从司的动词形式：If+主语+had+过去分词
主句的动词形式：I (we)should+have+过去分词,主语+could (might,could)+have ＋过去分词
例句：
·If you had taken my advice,you wouldn’thave failed in the examination.(fact:You did not take my advice,so you have failed in the examination.)
·I would have checked my paper again if Ihad had more time at yesterday’s examination.(fact:I did not have more time at yesterday’s exam,so I didn’t checkmy paper again.)
·He would have already recovered from hisillness if he had seen the doctor in time.(fact:He didn’t see the doctor intime,so he has not recovered from his illness.)
