Grammar--- Subjunctive Mood 虚拟语气
一.定义: 虚拟语气是动词的一种特殊形式,它用来表示所说的不是事实或者是不 可能发生的事情,而是一种愿望、建议或与事实相反的假设。 二.虚拟语气的相关用法 1. if 引导的条件虚拟句的构成: (1)对将来进行虚拟: If sb. did/were to /should do, sb. would /should/could/might +do (2)对现在进行虚拟: If sb. did(were), sb. would/should/could/might +do (3)对过去进行虚拟: If sb. had done sth, sb.would/should/could/might +have done (1)If it should rain/were to rain/ rained tomorrow, the sports meeting would be put off. (2)If I had time, I would learn how to play the piano. If I were you, I would seize every chance to study English. (3)If you had taken his advice, you wouldn’t failthe test. 抄 以 上 例 句 并 背 诵 : ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 2.错综时间条件句:当条件状语从句表示的行为和主句表示的行为发生的时间不一致时,被 称作“错综时间条件句”,动词的形式要根据它所表示的时间 作出相应的调整。 If you had followed my advice just now, you would be better now. If you had watered the flowers yesterday, they would live now. 抄 以 上 例 句 并 背 诵 : ________________________________________________________________________ ________________________________________________________________________ 3.省略 if 的条件虚拟句 当 if 引导的虚拟条件句中有 were, had, should 时, 可把 if 省去, were, had, should 把 提到句首,变为倒装句式。 If I were at school again, I would study harder. → Were I at school again, I would study harder. If you had come earlier, you would catch the bus. → Had you come earlier, you would catch the bus. If it should snow tomorrow, we would not go out. → Should it snow tomorrow, we would not go out. 抄以上例句并背诵

I was busy then. Otherwise, I would have help him. Without air, human beings couldn’t be able to survive. 抄 以 上 例 句 并 背 诵 : ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 5. 虚拟语气在名词性从句中的运用 (1) wish 后面的宾语从句一般用虚拟语气,表示一种不可能实现的愿望。其谓语 构成形式为: did/were(对现在) had done(对过去) could/would/ might + do (对将来) I wish I were ten years younger now. I wish that I had met him yesterday. I wish I would be a scientist. (2) sb. did (对现在或将来) would rather sb. had done (对过去) I would rather he didn’t hear of the news tomorrow.
