通過寫文章梗概，培養(yǎng)學生綜合運用語言的能力，學習用恰當的英語描述科學家的故事。這是本課的教學難點。教師可以使用完形填空的方式來幫助學生整理語篇，從而來降低難度。本課的教學重點的突破方法是：在閱讀前，讓學生初步了解得出科學觀點所需要的基本程序，從而輕松而自然地導入文章的閱讀；在閱讀過程中，由易到難設計快速閱讀和精讀的問題，層層推進各種閱讀活動，讓學生對閱讀內容從整體感知到細節(jié)理解，最后深層讀懂整篇文章，同時加強閱讀策略的指導，讓每個學生都主動參與課堂教學活動，最終達到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作，在老師的適當指導下，就以下2個問題展開討論，讓學生就所知、所學、所感和所想融入話題，然后抽若干同學代表作小組發(fā)言。1.

《拿來主義》說課稿（四） 統(tǒng)編版高中語文必修上冊
【教學目標】根據課程標準的要求，結合魯迅雜文的特點以及學生的實際情況，制定如下目標：⑴知識與技能目標：把握文章思路、結構和觀點；揣摩魯迅雜文犀利、幽默、詼諧的語言風格。⑵過程與方法目標：學習運用因果論證和比喻論證的寫作手法。⑶情感態(tài)度及價值觀目標：正確對待中外文化遺產，樹立辯證唯物主義和歷史唯物主義的觀點。【教學重難點】根據教學目標和學生實情，確定教學重點如：學習因果論證的寫作方法，體會作者推理的邏輯性；揣摩魯迅雜文犀利、幽默、詼諧的語言風格。確定教學難點如：學習掌握比喻論證的方法；明確為什么要實行“拿來主義”，著重認識送去主義的實質和危害。二、教學方法教學應堅持“以學生為主體”的原則，盡可能發(fā)揮學生學習的能動性和主動性，培養(yǎng)學生獨立思考的能力，調動學生學習積極性，因此本文采用“疑問教學法”相對合適。
人教版高中語文必修2《涉江采芙蓉》說課稿2篇
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。《古詩十九首》在中國古代詩歌的藝術手法上起著承前啟后的作用，在高中語文古詩教學中也起著承前啟后的作用。這首古體詩不論是藝術上，還是在思想上都已經達到了十分純熟的境界。因此，它十分重要。2.說學情這首詩歌在內容上難度不大，可以做多角度解讀。新課程標準鼓勵學生作個性化解讀，我們可以引導學生就此作些探討。學生通過小學、初中的系統(tǒng)學習和本冊古詩部分的集中學習，有了一定的古詩鑒賞能力，對源遠流長的中華文化也有了一些積淀，興趣漸濃，這是進一步引導學生熱愛古代詩歌、學習古代詩歌的一個前提。3.教學目標依據學生特點，教材特色以及新課標的要求，制定教學目標如下：（用多媒體展示）1、了解關于《古詩十九首》的文學常識;2、感受詩歌的思想內涵;3、運用想象描摹詩歌的藝術畫面。
人教版高中語文必修2《蘭亭集序》說課稿3篇
（二）分析課文，理清思路第1、2段為第一部分，主要是敘事、寫景，先敘述集會的時間、地點，然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽之娛”，可以自由地觀察、思考，滿足人們目視耳聞的需求。這里正是與會“暢敘幽情”、盡興盡歡的絕好處所。這些描寫都富有詩情畫意，作者的情感是輕松愉快的。第3、4段為第二部分，主要是抒情、議論，作者由美景妙時引發(fā)出樂與憂、生與死的感慨。他認為人生的快樂是有極限的，待快樂得到滿足時，就會感覺興味索然。往事轉眼間便成為歷史，人到了生命的盡頭就會死亡。作者由“一死生為虛誕，齊彭殤為妄作”的認識，產生了一種珍惜時間、眷戀生活、熱愛文明的思考。雖然文中的壽夭、生死不能自由決定，從而有些傷感，但作者仍然認識到盛衰、生死是必然的。人生無常，時不我待，故著文留傳后世，以承襲前人，啟示來者。
人教版高中語文必修1《鴻門宴》說課稿3篇
3、拓展延伸，啟迪心智，創(chuàng)設課堂訓練營。三、說學法1、紙上得來終覺淺，圈點、勾畫、批注法，學好文言基本功。2、自主合作加探究，眼耳口腦手并用，破疑解難在其中。四、說課時安排《鴻門宴》篇幅較長，文言知識較豐富，文章內涵豐厚，因此我設計用五課時教學本文。第一課時：了解作家作品，積累文言知識，感受作者隱忍發(fā)憤的著書精神（初讀）第二課時：理清故事情節(jié)，概括人物形象，學習客觀地評論歷史人物，（熟讀）第三課時：進一步梳理文言知識，精讀課文，要求讀透。（精讀）第四課時：通過對人物、事件的賞析，加深學生對人物的理解，鍛煉學生的開放性思維，由學生自主認識到人物的性格，悲劇的原因等問題。（賞讀）第五課時：補充課本教學內容：同學生一起閱讀古今關于劉邦項羽的一些篇章：讓學生投入進來，把握自己眼中的項羽。（展讀）在文言文學習的過程中，采取五步學習法：初讀-熟讀-精讀-賞讀-展讀（板書）
人教版高中語文必修1《優(yōu)美的漢字》說課稿
明確：（1）結繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時，常用在繩索或類似物件上打結的方法記錄數字，表達某種意思，用以傳達信息，處理事件。 （2）書畫說。（3）倉頡造字說。中國自古就有倉頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事，它將人們的思維、語言、經驗以及復雜的社會現(xiàn)象記錄下來，使文化得以傳播交流、世代傳承。2、漢字的形體：中華民族五千年的歷史中，漢字的演變，從甲骨文－－金文－－大篆－－小篆－－隸書－－草書－－楷書－－行書，字形由象形到點橫豎撇捺的方塊字，經歷了漫長的歲月。其中凝聚著民族的智慧，也體現(xiàn)出漢字逐步完善的過程，凸顯其方方正正、四平八穩(wěn)的特點。漢字又是一種文化的體現(xiàn)，那些經過藝術處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳，更是讓我們感到的是在欣賞漢字在紙張上跳舞，所以：書法是“紙上的舞蹈”。請大家看到書上的相關內容，注意每一種形體的漢字的載體是什么，其功能又有什么不一樣。
人教版高中語文必修1《燭之武退秦師》說課稿2篇
4、本文的重點是說辭，雖僅百余字，卻委婉曲折，步步進逼，層層深入，表現(xiàn)出高超的勸說藝術、游說技巧。讓學生細細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，以退為進，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之武面對大國的君主，巧舌如簧，不卑不亢，從容辭令，既不刺激對方也不失本國尊嚴，語言的分寸掌握得恰到好處。表現(xiàn)出燭之武機智善辯的外交才能。5、面對風云突變的局勢，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)、隨機應變的胸懷和謀略，正是晉文公終成霸業(yè)的根本原因。設計意圖：本環(huán)節(jié)的重點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)出的非凡的膽識以及高超的謀略和語言藝術。
人教版高中語文必修2《故都的秋》說課稿3篇
請一位朗誦水平較好的學生，有感情的朗讀課文12自然段，其他同學完成一項任務：這一段可否去掉？為什么？學生思考、圈畫、交流、討論，然后小組發(fā)言，其他小組補充，教師從旁予以點撥，引導學生進一步明確作者的思想情感。明確：作者要創(chuàng)造一種文化氛圍，于自然氣息之外再添一重文化氣息，與“故都”題旨暗合。從行文章法上看，這里是宕開文筆，縱橫議論，顯出深厚的文化底蘊和開闊的思路。這一段采用議論，通過古今中外的引證，說明感秋處處有，中國文人最突出，而秋“深味”非在中國北方莫屬，這其實還是為了突出故都之秋。（設計意圖：提高學生探究的能力，充分把握本文的教學內容，深刻體悟作者的情感，了解作者對秋的禮贊情感，從而突破教學難點。）
人教版高中語文必修3《過秦論》說課稿3篇
本文篇幅較長，并且有一字句不易理解，因而對高一學生來說完全讀懂內容有一些困難。這樣的話，老師就要做好引導工作，把一些難點，或是出現(xiàn)詞類活用比較多，局勢比較特殊的句子，老師可以先給學生畫出來，存疑，或是與同學們一起討論解決。對那些不易懂的字詞就引導學生聯(lián)系上下文提供的語境、前后涉及的情節(jié)加以推測、判斷，以培養(yǎng)學生依據文脈推斷詞義的好方法。要求學生點出重點實詞、框出通假字，主要是為幫助學生積累和掌握一些文言文中常見的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語，并進一步得出規(guī)律，指導今后的文言文學習。詞類活用和特殊句式在文言文翻譯中難度較大，也是本文教學的兩大難點。要求學生標出有活用現(xiàn)象的字和劃出句式特殊的句子，是基于兩點考慮：1、積累一定數量的第一手例句；2、引導學生加以分類，找出每類的相同特征，并抽取出來形成規(guī)律性的東西，從而上升到理性認識，使學生能由學會一個到會學多個。翻譯過程中注重指導學生養(yǎng)成用符號法表示重點字句的好習慣，如點、框、圈、劃線等符號應約定一致，便于突出翻譯中的重點、難點及復習。我的提示著重歸納了實詞“制”“亡”“遺”“利”等，名詞活用、形容詞活用、使動用法，被動句、狀語后置句。
人教版高中語文必修3《琵琶行 并序》說課稿2篇
說教材A．教材簡析《琵琶行（并序）》是人教版《普通高中課程標準實驗教科書語文》必修3第二單元的一篇講讀課文。本單元學習的是唐代詩歌，共七首詩?！杜眯校ú⑿颍肥翘拼F(xiàn)實主義詩人白居易寫的一首歌行體長篇敘事詩，是我國古代敘事詩和音樂詩中的“千古絕喝”。詩歌主題鮮明、人物形象生動，抒情真切細膩，具有深刻的思想內容和卓越的藝術技巧。B．教學目標《全日制普通高中高級中學語文教學大綱》明確要求我們：在閱讀教學過程中要引導學生“感受文學形象，品味文學作品的語言和藝術技巧，初步鑒賞文學作品”。而本單元的教學要求是培養(yǎng)學生詩歌鑒賞的能力。根據教學大綱和單元教學要求，結合本課特點，我制定本課的教學目標是：1．知識目標：了解文學常識；積累重點文言實詞；品味主旨句“同是天涯淪落人，相逢何必曾相識”的內涵；感知作者把音樂描寫與聽者、演奏者的感情融為一體的寫作特點。
人教版高中語文必修3《祝?！氛f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.

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
