人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

談到這，如果有人會(huì)說這僅僅是在于我個(gè)人與戰(zhàn)場(chǎng)之上，戰(zhàn)場(chǎng)之下另當(dāng)別論，那么，他完全錯(cuò)了。在我小學(xué)四年級(jí)的語文課上有兩個(gè)人發(fā)言積極，一個(gè)姓黃，一個(gè)姓康，黃同學(xué)發(fā)言比康同學(xué)更積極，班上的同學(xué)常以為黃同學(xué)是個(gè)了不得的人物，后來，教語文的吳老師曾悄悄地告訴我：班上真正厲害的是康x，那黃x沒什么，說的全是“一點(diǎn)通”上的，照搬不誤。說到這，我還得厚著臉皮自夸一下，在四年級(jí)時(shí)，我和康同學(xué)是同坐，一次，老師叫我們對(duì)一片課文（好象是寫黃繼光舍身炸暗堡）的一個(gè)段落提問題時(shí)，我悄悄地對(duì)康同學(xué)說了一個(gè)問題，康同學(xué)對(duì)我說：“你站起來說嘛。”內(nèi)向的我遙遙頭，康同學(xué)便站舉手，并起來將我的問題大聲地說了出來，結(jié)果老師說：“恩，康x的問題提得很好?！?/p>

探究、討論、交流：1、包弟討人喜歡，作者卻不得不將它送走，為什么？2、送走包弟后，作者為什么先是感覺輕松，隨后覺得沉重？3、“您的小狗怎樣？”這句話反復(fù)出現(xiàn)，有什么用意？4、“整整十三年零五個(gè)月過去了”“整整”一詞有什么作用？5、“滿園的創(chuàng)傷使我的心仿佛又給放在油鍋里熬煎”這句話如何理解？6、“我懷念包弟，我想向它表示歉意?！比绾卫斫?？學(xué)生各抒己見后教師結(jié)合材料發(fā)表看法明確總結(jié)特別是最后一個(gè)問題得出作者這發(fā)之心底的語言，不僅僅是歉意，更是發(fā)自靈魂深處的懺悔！是對(duì)生命的尊重，是一個(gè)有良知的作家對(duì)反省歷史的呼號(hào)。第三環(huán)節(jié)“認(rèn)識(shí)你自己”——懺悔意識(shí)與我引導(dǎo)學(xué)生正視和反省成長過程中曾犯下過錯(cuò)。并布置課后作業(yè)：要求學(xué)生課后在本周隨筆中談反省懺悔后的感受。
人教版高中語文必修1《燭之武退秦師》說課稿2篇
4、本文的重點(diǎn)是說辭，雖僅百余字，卻委婉曲折，步步進(jìn)逼，層層深入，表現(xiàn)出高超的勸說藝術(shù)、游說技巧。讓學(xué)生細(xì)細(xì)品味并概括說辭中包含幾層意思。第一層（“秦、晉圍鄭，鄭既知亡矣”），分析形勢(shì)，以退為進(jìn)，博得好感。第二層（“若亡鄭而有益于君”至“君之薄也”），亡鄭陪鄰，動(dòng)搖聯(lián)盟。第三層（“若舍鄭以為東道主”至“君亦無所害”），存鄭有益，利益引誘。第四層（“且君嘗為晉君賜矣”至“唯君圖之”），追溯歷史，深入離間?？梢姞T之武面對(duì)大國的君主，巧舌如簧，不卑不亢，從容辭令，既不刺激對(duì)方也不失本國尊嚴(yán)，語言的分寸掌握得恰到好處。表現(xiàn)出燭之武機(jī)智善辯的外交才能。5、面對(duì)風(fēng)云突變的局勢(shì)，晉侯沒有感情用事，而表現(xiàn)了清醒的頭腦和理智的判斷。這種隱忍不發(fā)、隨機(jī)應(yīng)變的胸懷和謀略，正是晉文公終成霸業(yè)的根本原因。設(shè)計(jì)意圖：本環(huán)節(jié)的重點(diǎn)是全面把握燭之武這一人物性格特征，以及退秦師過程中體現(xiàn)出的非凡的膽識(shí)以及高超的謀略和語言藝術(shù)。
人教版高中語文必修2《短歌行》說課稿2篇
一、說教材《短歌行》是普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書必修（二）第二單元的一篇略讀課文，本單元安排的是先秦到南北朝時(shí)期的詩歌?！抖谈栊小肥侵渭?、軍事家、文學(xué)家曹操的作品。詩中抓住“憂”字來寫詩人為什么“憂”，如何解“憂”，從而表達(dá)希望能夠招攬人才、完成統(tǒng)一天下的雄心壯志。所以本單元安排《短歌行》一詩，對(duì)學(xué)生全面了解曹操，感受曹操在短暫的人生中竭力創(chuàng)造偉業(yè)的氣概。二、說學(xué)生我這一課的教學(xué)對(duì)象是高一學(xué)生。他們進(jìn)入高中學(xué)習(xí)的時(shí)間只有三個(gè)多月，現(xiàn)在已經(jīng)完成了必修（一）的學(xué)習(xí)。學(xué)習(xí)了現(xiàn)代詩歌單元，有了一定的詩歌學(xué)習(xí)基礎(chǔ)，初步掌握了讀詩的基本方法，但是還未能形成成熟的穩(wěn)定的學(xué)習(xí)方式。同時(shí)，本單元學(xué)習(xí)是高中第一次接觸古代詩歌，詩歌語言上的障礙和時(shí)間上的跨度對(duì)他們來說都是學(xué)習(xí)上的困難。因此教師要引導(dǎo)學(xué)生自主學(xué)習(xí)，合作學(xué)習(xí)，為他們?cè)O(shè)置新的學(xué)習(xí)情境，提供合作探究的機(jī)會(huì)。
人教版高中語文必修2《囚綠記》說課稿2篇
“深入探究，把握主旨”這一步則是解決教學(xué)的重點(diǎn)難點(diǎn)，這里涉及到課文的深層意蘊(yùn)，學(xué)生理解有難度，教師在通過問題引領(lǐng)學(xué)生探討的基礎(chǔ)上，還要適時(shí)啟發(fā)、點(diǎn)撥，因?yàn)榻虒W(xué)時(shí)間有限，讓學(xué)生漫無邊際的討論，可能難以完成預(yù)定的教學(xué)任務(wù)，會(huì)使教學(xué)過程不完整。至于本文的寫作特點(diǎn)的教學(xué)視時(shí)間而定，有時(shí)間可以讓學(xué)生說一說，沒有時(shí)間用小黑板出示一下，讓學(xué)生了解就行，如果時(shí)間不夠，甚至可以不講。第三階段是“延伸練習(xí)，鞏固提高”。

三、文本中的句子解決完畢，大家對(duì)文本內(nèi)容的理解更加深入了。請(qǐng)速度文本，思考：《論語》具體涉及了哪些方面的內(nèi)容，體現(xiàn)了孔子什么觀點(diǎn)？明確：主要有治學(xué)、從政、修身養(yǎng)性和交友治道等方面，體現(xiàn)了孔子“克己復(fù)禮”的思想。四、 教師引導(dǎo)學(xué)生討論： 如何評(píng)價(jià)孔子的言行和觀點(diǎn)？從古至今人們對(duì)孔子有哪些評(píng)價(jià)？明確：1、春秋戰(zhàn)國時(shí)代， 孔子門人及其后學(xué)者均推尊孔子。門人中以子貢為代表，他對(duì)孔子贊美備至，奉如天人，把孔子比擬為高天、日月、木鐸，凡人是永遠(yuǎn)不可企及的，認(rèn)為孔子是天生的圣人，“仰之彌高，鉆之彌堅(jiān)”。亞圣孟子認(rèn)為孔子所行的“圣人之道”是遍及自然界和社會(huì)的至高準(zhǔn)則。然而當(dāng)時(shí)民間一般看法認(rèn)為孔子是博學(xué)成名的大學(xué)者。
人教版高中語文必修1《再別康橋》說課稿2篇
一、教材分析1、教學(xué)對(duì)象分析《再別康橋》的教學(xué)對(duì)象是高一學(xué)生，高一學(xué)生往往對(duì)那種純粹的、原始的、本真的情感體會(huì)較為膚淺，《再別康橋》是新月派詩人徐志摩的傳世之作，有極高美學(xué)價(jià)值，它所抒發(fā)的離愁別緒是人類共同的情感經(jīng)歷，通過誦讀容易將學(xué)生帶人詩境，喚醒他們沉寂的真情，從而引起強(qiáng)烈的共鳴。 2、教材地位及作用 高中語文第一冊(cè)第一單元為詩歌單元，本單元收錄了中國現(xiàn)當(dāng)代的一些優(yōu)秀詩篇?！对賱e康橋》安排在本單元的第二課，屬于必讀課。雖然本詩向來眾說紛紜，但其藝術(shù)之美人所共知，培養(yǎng)學(xué)生高尚的審美情趣和良好的審美創(chuàng)造力是語文學(xué)科的任務(wù)，因此，從語言賞析入手，從情感體驗(yàn)切入，就可以讓學(xué)生通過學(xué)習(xí)本課體會(huì)現(xiàn)代詩歌的特點(diǎn)，多方面感受體悟詩歌的情感，受到美的熏陶。
人教版高中語文必修2《我有一個(gè)夢(mèng)想》說課稿2篇
(2).教學(xué)手段為了使我根據(jù)教材而設(shè)計(jì)的三個(gè)教學(xué)目標(biāo)以及重點(diǎn)難點(diǎn)得以的突出和突破,達(dá)到最大化的展示境界,同時(shí)也為了配合以上我選擇的四種教法得以完滿實(shí)現(xiàn),我決定采用“多媒體”教學(xué)手段進(jìn)行全程教學(xué)。利用電腦的信息容量大,操作簡便等優(yōu)點(diǎn),形象生動(dòng)的直觀展示教學(xué)內(nèi)容,不但提高學(xué)習(xí)效率和質(zhì)量,而且容易激發(fā)學(xué)生的學(xué)習(xí)興趣和調(diào)動(dòng)學(xué)習(xí)的積極性。四、說學(xué)法我為學(xué)生設(shè)計(jì)了三個(gè)學(xué)習(xí)方法：1.讓學(xué)生學(xué)會(huì)在探究中學(xué)。通過“對(duì)黑人嚴(yán)酷處境的探究”和對(duì)文中重點(diǎn)語句的探究,培養(yǎng)學(xué)生在探究中學(xué)習(xí)的能力。2.讓學(xué)生學(xué)會(huì)在讀中學(xué)。通過“誦讀法”指導(dǎo)學(xué)生在誦讀過程中感受演講詞內(nèi)在的魅力,學(xué)會(huì)在讀中學(xué)。3.讓學(xué)生學(xué)會(huì)在練習(xí)中學(xué)。通過“課外延伸練習(xí)法”,對(duì)所學(xué)的知識(shí)進(jìn)行運(yùn)用,培養(yǎng)學(xué)生的創(chuàng)新和自學(xué)能力。
人教版高中語文必修1《包身工》說課稿2篇
（一）解題：包身工──舊社會(huì)一種變相的販賣奴隸的形式。被販賣的多是女孩子由承辦人送到工廠做工，無人身自由，所得工資全部歸承辦人所有，在這種形式下做工的人也稱包身工。包身工是指二三十年代（時(shí)間），在上海東洋紗廠里（地點(diǎn)），為外國人工作的女工（工作性質(zhì)）。因?yàn)檫@些女工在進(jìn)廠時(shí)已經(jīng)簽訂了賣身契，失去了人身的自由權(quán)，所以被稱為“包身工”。標(biāo)題中的“包身”二字，突出了帝國主義、封建勢(shì)力對(duì)中國女童工的殘酷剝削的罪行，控訴了他們的野蠻殘暴的統(tǒng)治手段，以激起人們的義憤和同情，這是全文的中心思想。（二）關(guān)于報(bào)告文學(xué)：《包身工》屬于報(bào)告文學(xué)。(同類題材有初中的《地質(zhì)之光》、《誰是最可愛的人》)報(bào)告文學(xué)，是文學(xué)體裁的一種，散文的一類，是文藝通訊、速寫、特寫的總稱，是文學(xué)創(chuàng)作中的“輕騎兵”。

一、說教材1．教材分析《涉江采芙蓉》是新人教版必修二第二單元《古詩三首》中的一首?！豆旁娛攀住吩谥袊糯姼璧乃囆g(shù)手法上起著承前啟后的作用，在高中語文古詩教學(xué)中也起著承前啟后的作用。這首古體詩不論是藝術(shù)上，還是在思想上都已經(jīng)達(dá)到了十分純熟的境界。因此，它十分重要。2.說學(xué)情這首詩歌在內(nèi)容上難度不大，可以做多角度解讀。新課程標(biāo)準(zhǔn)鼓勵(lì)學(xué)生作個(gè)性化解讀，我們可以引導(dǎo)學(xué)生就此作些探討。學(xué)生通過小學(xué)、初中的系統(tǒng)學(xué)習(xí)和本冊(cè)古詩部分的集中學(xué)習(xí)，有了一定的古詩鑒賞能力，對(duì)源遠(yuǎn)流長的中華文化也有了一些積淀，興趣漸濃，這是進(jìn)一步引導(dǎo)學(xué)生熱愛古代詩歌、學(xué)習(xí)古代詩歌的一個(gè)前提。3.教學(xué)目標(biāo)依據(jù)學(xué)生特點(diǎn)，教材特色以及新課標(biāo)的要求，制定教學(xué)目標(biāo)如下：（用多媒體展示）1、了解關(guān)于《古詩十九首》的文學(xué)常識(shí);2、感受詩歌的思想內(nèi)涵;3、運(yùn)用想象描摹詩歌的藝術(shù)畫面。
高中物理人教版必修一《彈力》說課稿
二、學(xué)情分析：學(xué)生目前對(duì)形變和彈力有一定的感性認(rèn)識(shí)但是不夠深入；知道支持力、壓力都是彈力，但是不能夠概括產(chǎn)生的原因。理性思維還沒有達(dá)到一定的層次，要想理解彈力這一抽象概念還有一定困難。因此我采取引導(dǎo)、啟發(fā)的教學(xué)方式。

什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學(xué)生初步理解隔離的概念之后，可以安排學(xué)生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學(xué)生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個(gè)問題。最后教師應(yīng)強(qiáng)調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個(gè)物種的兩個(gè)種群，就成了兩個(gè)物種。關(guān)于“共同進(jìn)化與生物多樣性的形成”內(nèi)容的教學(xué)，可以學(xué)生自學(xué)為基礎(chǔ)，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進(jìn)教學(xué)過程。使學(xué)生理解共同進(jìn)化的含義，無機(jī)環(huán)境的變化、無機(jī)環(huán)境的復(fù)雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復(fù)雜化和多樣化對(duì)生物多樣性形成的作用。最后，組織學(xué)生討論生物進(jìn)化理論在發(fā)展。
