江蘇省灌南高級中學高三英語一輪復習虛擬語氣教案 譯林牛津版step one lead in 選用bread樂隊的一首經(jīng)典老歌 “if”作為熱身。要求學生在欣賞歌曲的同時，寫出歌詞中空缺的單詞。歌詞如下：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條件從句所述情況if 從句主句與現(xiàn)在相反過去式/be werewould/could/might/should do與過去相反had donewould/could/might/shouldhave done與將來相反did /were to /shouldwould/could/might/should dopart two: discovery and practice2. 錯綜時間條件句和省略if的條件句有時候，條件和結果不是指同一個時間，這時，應根據(jù)上面談到的幾種情況，使用相應的形式，這種虛擬語氣形式被稱為錯綜虛擬語氣。例) if it were christmas day today, i would have bought some presents last weekend.1.總結: 條件從句的動作和主句的動作時間不一致時, 動詞的形式要作相應的調整.假如你接受了我的意見，你現(xiàn)在就會好的多。you much better now if you my advice.要不是你誤了公共汽車的話，我們現(xiàn)在正在聽音樂會呢if you_ the bus, we _ the concert now.2.若從句中有were, had, should,可把if 省略，而把_放在主語前，從句部分形成倒裝結構。例如： 要是我了解電腦程序，會節(jié)省大量的時間和能量had i known about this computer program, a huge amount of time and energy_ . 如果明天下雨，我們將不得不取消球賽。should it rain tomorrow, we would have to_.3.含蓄式條件句有時為了表達的需要，虛擬語氣中并不總是出現(xiàn)if引導的條件句，而通過其他介詞,介詞短語或副詞等來替代。如：without, with，but for, or (else), otherwise，under，in等。1) we couldnt have succeeded without your help.
