在虚拟条件状语中如果有were, should, had这三个词主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句 中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可 说 Were I not to do., 而不能说 Weren't I to do.

2.假设条件虚拟倒装。 条件从句中有should， were， had三个助动词可以把if省略，并将 这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up.

虚拟语气假设条件句型注意点： 1.假设条件从句谓语动词发生的时间与主句 所假设的谓语动词不一致，叫做错综条件 虚拟语气。主句和从句的谓语动词要依照 假设的时间而定。 If the weather had been finer, the crops would be growing still better. If you had followed the teacher’s advice, you wouldn’t be in the hospital.

If only I knew his name! If only we had followed your advice!

If only I could see him again!
要是我们的父母能和我们住在一起就好了。 要是我没错过火车就好了！ If only our parents could live with us! If only I hadn’t missed the train!

在条件状语从句中,表示与事实相反的条件和结果。 1) 与现在事实相反：  If 主语 …, 主语 should (would +V原 were 2)与过去事实相反： could, might) V-ed  If 主语 ,主语 +have Ved should (would had Ved 3)与将来事实相反： could, might)  If 主语 …, 主语 +V原
