公開課教案虛擬語氣

1、5虛擬語氣 含山縣職教中心2016-2017學(xué)年度第二學(xué)期教師公開示范課教案公開課教師：周靜公開課時間：2017年2月23日上午第二節(jié)課公開課地點：高三計算機(jī)2班Subjunctive Mood 虛擬語氣 專題復(fù)習(xí)1 教學(xué)目標(biāo)： 虛擬語氣是高考的重點，且難度較大。本次課程通過對虛擬語氣知識點的復(fù)習(xí)講解，總結(jié)概括，讓學(xué)生知道虛擬語氣是用來表示人的主觀的愿望和假想，達(dá)到學(xué)生對知識點的熟練運(yùn)用，在腦海中形成具有條理性的知識框架的目的。2 教材分析： 虛擬語氣是高考英語重點和難點，掌握好虛擬語氣的重要性對每個參加高考的學(xué)生不言而喻。這次課程是高三第一輪復(fù)習(xí)時對虛擬語氣的再次講解和梳理，全部的知識都經(jīng)過

2、了高度的總結(jié)合概括，均是高考考點。 3 學(xué)生特征分析： 輔導(dǎo)的學(xué)生是高三年級，刻苦努力，理解能力較強(qiáng)，有一定的基礎(chǔ)?；局R掌握一般，且很多重要的知識點已經(jīng)遺忘 4 教學(xué)重點難點： 1、 真實條件句和非真實條件句的用法。 2、 虛擬語氣用在主語從句，表語從句，同位語從句，定語從句中 的用法。 3、 情態(tài)動詞+ have + done的用法。五教學(xué)過程一定義：虛擬語氣是一種動詞形式，表示說話人的一種愿望，假設(shè)，懷疑，猜測，建議等含義。虛擬語氣所表示的含義不是客觀存在的事實。二虛擬語氣在非真實條件句中1.概念 真實條件句：表示現(xiàn)實或可能變?yōu)楝F(xiàn)實的條件。 非真實條件句：表示非現(xiàn)實的，或不可能，或不大

3、可能變?yōu)楝F(xiàn)實的條件。 e.g. I will go fishing if it doesnt rain tomorrow. If I were a bird, I could fly in the sky.2.形式 虛 擬 條 件 句 主 句 與現(xiàn)在事實相反動詞過去式（be動詞用were）should/would/could/might+do 與過去事實相反had+doneshould/would/could/might+have+done 與將來事實相反動詞過去式should+dowere to+doshould/would/could/might+doe.g. If you had got

4、 up earlier,you could have caught the train.If he came tomorrow,we could ask him.練習(xí)：If you (take) my advice,you (not fail) in the exams last term.If it (rain) tomorrow,the sports meeting (put off).If everyone (know)first aid,many lives (save).3. 重點：混合虛擬語氣和含蓄虛擬語氣以及虛擬語氣的倒裝1)有些句子主句謂語和從句謂語表示的動作在時間上并不一致，

5、這類句子稱為“錯綜時間條件句”。 If you had studied hard before,you would be a college student now. If he hadnt followed my advice,he wouldnt do it much better like this.2）含蓄條件句指句中沒有明顯的虛擬條件句，而是利用其它手段來暗示存在的虛擬條件，如but for,with,without,otherwise,but等。 But for your help,we couldnt have finished the work.=If it had not b

6、een for your help, I might have given your more help,but I was too busy. Such a thing wouldnt have happened elsewhere. I was ill that day.Otherwise,I would have taken part in the meeting.3）如條件句中有were,had,should,可把if省略掉，把were,had,should提前，變?yōu)榈寡b句式。 e.g. If we had made a great effort,we might have succe

7、eded. Had we made a great effort,we might have succeeded.注意：若條件句的謂語動詞是否定形式時，不能用動詞的縮略形式。 e.g. If it werent for the expense,I would go abroad now. Were it not for the expense,I would go abroad now.3 虛擬語氣其它用法1.用于賓語從句中1）wish后的賓語從句用虛擬語氣，表示一種不可能實現(xiàn)的愿望。謂語形式：過去式（賓語從句動作與wish同時）had+done(賓語從句動作先于wish)could/woul

8、d/might+do（賓語從句動作后于wish） e.g. I wish (that) I were a flying bird. I wish (that) I had met that film star yesterday. I wish he would try again.2）省去主句的條件句常用if only引導(dǎo)，表示一種不可能實現(xiàn)的愿望。謂語形式： 謂語用過去式（與現(xiàn)在事實相反） 謂語用had done（與過去事實相反） 謂語用could/would/might+do（與將來事實相反） e.g. If only he were here. If only the rain wou

9、ld stop.3) as if/as though用在虛擬語氣中。 as if/as though引導(dǎo)表語從句與方式狀語從句皆可，謂語形式： 過去式（從句動作與主句動作同時發(fā)生） had done（從句動作先于主句動作） could/would/might+do（從句動作后于主句動作） e.g. He looks as if he were a pop star. They talked about L.A. as if they had been there.4) would rather后的賓語從句用過去式表示與現(xiàn)在或?qū)硎聦嵪喾?，用過去完成式表示與過去事實相反。 e.g. Id rat

10、her you went home now. Id rather you hadnt made that mistake.2.用于表示建議、命令等詞后的賓語從句中，如demand,order,require,insist,suggest,propose,advise等。賓語從句的虛擬語氣結(jié)構(gòu)為：(should)+do e.g. He ordered that the boy (should) go with him.注意：當(dāng)suggest作“暗示；表明”講，insist作“堅持說；堅持認(rèn)為”講，賓語從句不用虛擬語氣。 e.g. The look on his face suggested th

11、at he was angry. Mike insisted that he had never stolen anything.3.用于主語從句中 It is suggested/proposed/necessary/important/strange/natural/desired+that從句 It is a pity/a shame/no wonder+that從句 主語從句的虛擬語氣結(jié)構(gòu)為：（should）+do（表達(dá)說話者“驚訝、遺憾、應(yīng)該”等語氣） e.g. It was a pity that our team should lose the game.注意：以上句式也可用陳述語氣。 e.g. Its strange that he didnt come yesterday.4.用于表語從句和同位語從句中 在名詞advice,order,suggestion,request,proposal,plan,idea等后邊that引導(dǎo)的同位語從句，或這些名詞作主語時后面that引導(dǎo)的表語從句中，虛擬語氣結(jié)構(gòu)為：(should)+do e.g. We all agreed to his suggestion that we (should) give up the plan.
