高中英語(yǔ)：教案：人教版選修六Unit4 language points

1、Book 6 Unit 4 Global WarmingLearning language points 教學(xué)設(shè)計(jì)教材分析：本單元的中心話題是人類(lèi)當(dāng)今面對(duì)的環(huán)境問(wèn)題，主要討論了“全球變暖”和“節(jié)約能源”等方面 的問(wèn)題?！罢Z(yǔ)言學(xué)習(xí)”局部是對(duì)課文中重點(diǎn)詞語(yǔ)詞組和句型的講解。教學(xué)設(shè)計(jì)思想：這節(jié)課是在講完課文閱讀理解后所設(shè)計(jì)的一節(jié)課，主要是針對(duì)課文中的重點(diǎn)詞語(yǔ)詞組和句型 的講解。課文中的詞語(yǔ)用法比擬簡(jiǎn)單，無(wú)需多講解，所以，設(shè)計(jì)的初衷就是教給學(xué)生如何記 憶單詞。將文中的關(guān)鍵單詞分成了同一個(gè)話題，近義詞，反義詞，詞性轉(zhuǎn)化四個(gè)局部讓學(xué)生 來(lái)記憶單詞。記背單詞本身就是學(xué)生的軟肋，這樣的設(shè)計(jì)也對(duì)學(xué)生今后的英語(yǔ)學(xué)

2、習(xí)有很大幫 助。在單詞后，通過(guò)圖片強(qiáng)化學(xué)生對(duì)這些單詞的認(rèn)識(shí)。在單詞講解后，介紹文章中的兩個(gè)重 點(diǎn)句型，并且通過(guò)學(xué)生非常熟悉的話題進(jìn)行訓(xùn)練。在前面的鋪墊之后，讓學(xué)生通過(guò)辯論的形 式來(lái)運(yùn)用所學(xué)詞匯。辯論的話題也與本單元話題緊密相關(guān)，培養(yǎng)了學(xué)生保護(hù)環(huán)境的意識(shí)。最 后的作業(yè)就是寫(xiě)一篇正反議論文。讓學(xué)生將課堂所學(xué)進(jìn)行訓(xùn)練。教學(xué)目標(biāo)：.讓學(xué)生通過(guò)不同的方法來(lái)記憶單詞。.讓學(xué)生通過(guò)圖片來(lái)了解句型結(jié)構(gòu)的基本用法。.讓學(xué)生通過(guò)辯論的形式來(lái)鞏固詞語(yǔ)和句型結(jié)構(gòu)的運(yùn)用。.培養(yǎng)學(xué)生保護(hù)環(huán)境的意識(shí)。教學(xué)重點(diǎn)和難點(diǎn)：如何讓學(xué)生運(yùn)用所學(xué)的詞語(yǔ)和句型在辯論中進(jìn)行運(yùn)用。教學(xué)過(guò)程：Step 1. Lead-inBrainstorm

3、 words about disasters concerned with global warming.設(shè)計(jì)說(shuō)明：以競(jìng)賽的形式讓學(xué)生在10秒內(nèi)盡可能多的寫(xiě)出與全球變暖有關(guān)的詞語(yǔ)，可以激 發(fā)學(xué)生上課的興趣。另外，本節(jié)課目的之一是告訴學(xué)生如何來(lái)記憶單詞。這個(gè)步驟就自然的 導(dǎo)入到下一個(gè)環(huán)節(jié)：通過(guò)同一個(gè)話題來(lái)記憶單詞。所講詞匯也是課文中的詞匯。Step 2.Learning about wordsGuide students to learn how to remember words:The same topic:Catastrophe: famine, floods, drought .Anto

Subjunctive moodTask2: Give four pictures and ask students to make up sentences with the structure:It is the program that.It is quantities of cars that.Without money,.Without cars, .設(shè)計(jì)說(shuō)明：這個(gè)步驟操練句型，并且借助于很流行的節(jié)目爸爸去哪兒，學(xué)生會(huì)覺(jué)得 有話可說(shuō)。轎車(chē)也與本單元話題息息相關(guān)。設(shè)計(jì)非常合理，學(xué)生容易上口，有話可說(shuō)。為后
