英语动词有三种语气， 陈述语气，祈使语气和虚拟语气. 用来表示说的话不是事实，或者是不可能发生的情况，而是一种愿望，建议，假设的语气叫虚拟语气 Subjunctive mood 虚拟语气 1. 条件句中的虚拟语气 1. If I had lunch, I would know because I wouldn’t feel hungry. 2. If I were you, I would give AIDS patient a hug. 3. If I had taken your advice, I wouldn’t have made a mistake. 4. If he had been there, it wouldn’t have happened. 5. If it should rain tomorrow, they wouldn’t go for an outing. 6. I think we could do it, if we planned it properly and could borrow the tools. 7. If we were to have three days off , we would enjoy a very happy life. 2 . 条件句中虚拟语气的倒装 假设条件虚拟倒装。 条件从句中含有 should，were， had 三个助动词并且放在句首时，可以把if省略。 If I were you, I would give it up.
