高中英語虛擬語氣教案

1、.課程說明教學目標：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習講解，總結概括，讓學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生不言而喻。這次課程是高三第一輪復習時對虛擬語氣的再次講解和梳理，全部的知識都經過了高度的總結合概括，均是高考考點。學生特征分析：輔導的學生是高三年級，刻苦努力，理解能力較強，有一定的基礎。基本知識掌握一般，且很多重要的知識點已經遺忘。教學重點難點：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。課前準備：教學方法：一對一輔導，面對面答疑，培養(yǎng)學生對英語的理解表達和思維的能力，同時安排適當的練習，保證學生能夠當堂消化所講內容。教學器材：黑板，粉筆，草稿紙，教案，給學生的資料，如果有條件可以適當運用多媒體。時間分配：講課40分鐘，做練習題20分鐘。課程設計：一、導入：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.之前學過還有印象嗎.通過提問問題激發(fā)學生的思考能力，再次對學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，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：表示現實或可能變?yōu)楝F實的條件。非真實條件句：表示非現實的，或不可能，或不大可能變?yōu)楝F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，并且讓學生當堂記憶。 虛 擬 條 件 句 主 句 與現在事

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（在給學生一段記憶時間后，讓學生運用虛擬語氣造句，保證學生已經對所講內容消化吸收。）三、講解重點內容和特殊情況 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（此部分不要求學生掌握過多，因此在講解之后給出題目，要求學生在

5、課后鞏固復習。）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構為：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引導的同位語從句，或這些名詞作 主語時后面that引導的表語從句中，虛擬語氣結構為：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題，讓學

8、生當堂做出，并且進行輔導講解，讓學生運用更加靈活。）教師活動：在課程設計里，教師通過講解知識，讓學生更加輕松的記憶知識點，梳理學生的知識結構。在學生掌握之后輔導學生做題。設計理念：由于學生處在高三這一特殊階段，學習能力和理解能力相比較于高一高二已經有了一個較大的提高，且知識已經學過一遍，因此教師要保證學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。教學反思：高三的特殊性決定了學生在學習英語時無法進行口語或者聽力的練習，同時由于沒有學習英語的環(huán)境，使得學生在學習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，這樣大部分學生在學習英語的時候就會失掉很多

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