江苏省灌南高级中学高三英语一轮复习虚拟语气教案 译林牛津版step one lead in 选用bread乐队的一首经典老歌 “if”作为热身。要求学生在欣赏歌曲的同时，写出歌词中空缺的单词。歌词如下：if a picture _paints_ (paint) a thousand words,then why cant i paint you?the words will never show,the you ive come to know.if a face could launch (launch) a thousand ships,then where am i to go?theres no one home but you.youre all thats left me to.and when my love for life is running dry,you come and pour yourself on me.if a man could be (be) two places at one time, id be (be) with you.tomorrow and today, beside you all the way.if the world should stop (stop) revolving,spinning slowly down to die,id spend (spend) the end with you.and when the world was through.then one by one the stars would go out.then you and i would simply fly away.step two grammarpart one: lead in1.if条件从句所述情况if 从句主句与现在相反过去式/be werewould/could/might/should do与过去相反had donewould/could/might/shouldhave done与将来相反did /were to /shouldwould/could/might/should dopart two: discovery and practice2. 错综时间条件句和省略if的条件句有时候，条件和结果不是指同一个时间，这时，应根据上面谈到的几种情况，使用相应的形式，这种虚拟语气形式被称为错综虚拟语气。例) if it were christmas day today, i would have bought some presents last weekend.1.总结: 条件从句的动作和主句的动作时间不一致时, 动词的形式要作相应的调整.假如你接受了我的意见，你现在就会好的多。you much better now if you my advice.要不是你误了公共汽车的话，我们现在正在听音乐会呢if you_ the bus, we _ the concert now.2.若从句中有were, had, should,可把if 省略，而把_放在主语前，从句部分形成倒装结构。例如： 要是我了解电脑程序，会节省大量的时间和能量had i known about this computer program, a huge amount of time and energy_ . 如果明天下雨，我们将不得不取消球赛。should it rain tomorrow, we would have to_.3.含蓄式条件句有时为了表达的需要，虚拟语气中并不总是出现if引导的条件句，而通过其他介词,介词短语或副词等来替代。如：without, with，but for, or (else), otherwise，under，in等。1) we couldnt have succeeded without your help.
