高中英語虛擬語氣教案

1、.課程說明教學(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，達到學(xué)生對知識點的熟練運用，在腦海中形成具有條理性的知識框架的目的。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)過了高度的總結(jié)合概括，均是高考考點。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，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。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

2、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。課前準(zhǔn)備：教學(xué)方法：一對一輔導(dǎo)，面對面答疑，培養(yǎng)學(xué)生對英語的理解表達和思維的能力，同時安排適當(dāng)?shù)木毩?xí)，保證學(xué)生能夠當(dāng)堂消化所講內(nèi)容。教學(xué)器材：黑板，粉筆，草稿紙，教案，給學(xué)生的資料，如果有條件可以適當(dāng)運用多媒體。時間分配：講課40分鐘，做練習(xí)題20分鐘。課程設(shè)計：一、導(dǎo)入：If you were to succeed, everything would be all right.If you had asked him yesterday, you would know what to d

3、o now.（這兩個句子是什么形式.之前學(xué)過還有印象嗎.通過提問問題激發(fā)學(xué)生的思考能力，再次對學(xué)生的知識掌握能力進行了解。）二、講解虛擬語氣基本知識 什么是虛擬語氣.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。 虛擬語氣在真實條件句非真實條件句中真實條件句：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，或不大可能變?yōu)楝F(xiàn)實的條件。（老師舉例說明真實條件句和非真實條件句。） 列表記憶由于虛擬語氣的知識點雜亂，通過列表能夠較輕松的記憶，在黑板上畫圖，并且讓學(xué)生當(dāng)堂記憶。 虛 擬 條 件 句 主 句 與現(xiàn)在事

4、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Ha + 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 +do（在給學(xué)生一段記憶時間后，讓學(xué)生運用虛擬語氣造句，保證學(xué)生已經(jīng)對所講內(nèi)容消化吸收。）三、講解重點內(nèi)容和特殊情況 什么情況下省略if. 什么是錯綜時間條件句. 什么是含蓄條件句. if only條件句的用法（此部分不要求學(xué)生掌握過多，因此在講解之后給出題目，要求學(xué)生在

5、課后鞏固復(fù)習(xí)。）四、虛擬語氣在從句中怎樣用. 如何用于賓語從句中.1、 wish2、demand, order, require, insist, suggest, propose, advise等。賓語從句的虛擬語氣結(jié)構(gòu)為：should + do3、would rather 如何用于主語從句中.Itisproposed/necessary/important/strange/natural /desired + that從句 It is a pity/a shame/no wonder + that從句 如何用于表語從句和同位語從句中. 在名詞 advice, order, suggesti

6、on, 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 如何用于定語從句中.It is high time + that從句，從句謂語形式用過去式，或should + do(should不可省略)。 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）

7、 情態(tài)動詞+ have + done怎樣用.1、must have done2、can/could have done3、cant/couldnt have done4、may/might have done5、should/ought to have done6、shouldnt/ought not to have done7、neednt have done8、had better have done9、would rather have done10、would like/love to have done sth（由于此部分難度較大，且知識體系龐雜。因此在講過之后就給出例句和習(xí)題，讓學(xué)

8、生當(dāng)堂做出，并且進行輔導(dǎo)講解，讓學(xué)生運用更加靈活。）教師活動：在課程設(shè)計里，教師通過講解知識，讓學(xué)生更加輕松的記憶知識點，梳理學(xué)生的知識結(jié)構(gòu)。在學(xué)生掌握之后輔導(dǎo)學(xué)生做題。設(shè)計理念：由于學(xué)生處在高三這一特殊階段，學(xué)習(xí)能力和理解能力相比較于高一高二已經(jīng)有了一個較大的提高，且知識已經(jīng)學(xué)過一遍，因此教師要保證學(xué)生在聽過課程之后對知識能夠熟練運用和掌握，且能對此有深刻的記憶。教學(xué)反思：高三的特殊性決定了學(xué)生在學(xué)習(xí)英語時無法進行口語或者聽力的練習(xí)，同時由于沒有學(xué)習(xí)英語的環(huán)境，使得學(xué)生在學(xué)習(xí)英語的時候只能一味的做題，背課文，理解語法等。而老師也只能進行填鴨式的教育，這樣大部分學(xué)生在學(xué)習(xí)英語的時候就會失掉很多

9、樂趣，可能會導(dǎo)致一些學(xué)生對英語產(chǎn)生反感和厭惡的心理，不利于學(xué)生的長遠發(fā)展。附：虛擬語氣習(xí)題1.Everything _ if Albert hadnt called the fire brigade.
