Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”； “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

人教版高中語文必修3《動物游戲之迷》教案2篇
一、內(nèi)容與解析內(nèi)容：科普說明文《動物游戲之謎》。解析：《動物游戲之謎》是高中語文（必修）3第四單元的一篇科普說明文?？茖W(xué)是人類認(rèn)識世界的重要工具，是人類文化的重要組成部分，是標(biāo)志人類文明的尺度。閱讀科普文章，可以啟迪心志，激發(fā)想象，帶領(lǐng)我們進(jìn)入全新的科學(xué)天地，在科學(xué)海洋中遨游。本文思路清晰，內(nèi)容生動，揭開了動物日常游戲行為的神秘面紗，擺出研究者的種種結(jié)論，既讓我們擴(kuò)大了視野，增長了知識，也讓我們明白了科學(xué)探索永無止境。學(xué)習(xí)本文的重點是提高的科普文的閱讀能力，培養(yǎng)學(xué)生勤于探索、勇于鉆研的科學(xué)精神。二、教學(xué)目標(biāo)及解析1、理清文章思路，明確本文的說明內(nèi)容和順序。2、品讀文章，感受本文的語言特色。3、激發(fā)探究興趣，培養(yǎng)篩選信息、提取要素及概括敘述的能力。4、挖掘人文內(nèi)涵，培養(yǎng)學(xué)生保護(hù)動物的意識和勤于探索、勇于鉆研的科學(xué)精神。
人教版高中語文必修3《蜀道難》教案2篇
【明確】“一夫當(dāng)關(guān)，萬夫莫開”言劍閣有易守難攻的險要形勢，暗示中央朝廷的部隊很不容易打進(jìn)來，因而野心家可以據(jù)險發(fā)動叛亂，“化為狼與豺”，搞地方割據(jù)。如果割據(jù)勢力之間出現(xiàn)矛盾沖突，難免要發(fā)生混戰(zhàn)，結(jié)果必定是“殺人如麻”。詩人這番預(yù)言在十多年后就得到了證實：從上元二年到大歷初即有段子璋、徐知道、崔旰等人相繼發(fā)動叛亂。詩人的意圖是要嚴(yán)防野心家發(fā)難。詩人從劍閣的險要引出對政治形勢的描寫。他化用西晉張載《劍閣銘》中形勝之地，匪親勿居的語句，目的在于勸人引以為鑒戒，警惕戰(zhàn)亂的發(fā)生，并聯(lián)系當(dāng)時的社會背景，揭露了蜀中豺狼的磨牙吮血，殺人如麻，這既是描寫蜀道猛獸，又是影射政治黑暗的雙關(guān)語句，表達(dá)了對國事的憂慮與關(guān)切，為詩篇增加了現(xiàn)實的內(nèi)涵、深厚的意蘊。唐天寶初年，太平景象背后正潛伏著危機，后來發(fā)生的安史之亂，證明詩人的憂慮是有現(xiàn)實意義的。
人教版高中歷史必修3美術(shù)的輝煌教案2篇
畫中的諸多圖像反映了畫家對于傳統(tǒng)繪畫因素的吸收。那個懷抱死去孩子的母親圖像，似乎是源自哀悼基督的圣母像傳統(tǒng)；手持油燈的女人，使人聯(lián)想起自由女神像的造型；那個高舉雙手仰天驚呼的形象，與戈雅畫中愛國者就義的身姿不無相似之處；而那個張臂倒地的士兵形象，則似乎與意大利文藝復(fù)興早期某些戰(zhàn)爭畫中的形象，有著姻親關(guān)系。由此可以看出，畢加索不僅是一位富于叛逆精神的大膽創(chuàng)新者，同時也是一位尊崇和精通傳統(tǒng)的藝術(shù)家。教師須強調(diào)：現(xiàn)代主義美術(shù)是現(xiàn)代美術(shù)流派的總稱，現(xiàn)代美術(shù)流派眾多，多姿多彩，但它們也表現(xiàn)出許多共同的特征。在技法上，它們大都反對傳統(tǒng)的寫實主義，追求新奇，空間結(jié)構(gòu)錯亂，色彩配置隨意，點線紊亂，缺乏透視可謂它們共有的特點。在創(chuàng)作主旨上，它們都主張強調(diào)自我，表現(xiàn)個人情感和內(nèi)心世界。可以說，現(xiàn)代美術(shù)藝術(shù)再現(xiàn)了20世紀(jì)西方世界的精神狀況。

人教版高中語文必修3《寡人之于國也》說課稿2篇
（明確：“寡人之于國也，盡心焉耳矣”，但“寡人之民不加多，何也？”）②他認(rèn)為自己對國家政務(wù)盡心盡力了，他有哪些具體做法？（明確：移民移粟）③第2—4節(jié)中孟子是怎樣說明梁惠王移民移粟的措施與“鄰國之政”并無本質(zhì)區(qū)別的？（明確：孟子不直接回答“民不加多”的問題，而是用梁惠王熟悉的“戰(zhàn)”設(shè)喻——設(shè)圈套，誘使對方在不知不覺中說出“不可，直不百步耳，是亦走也?！保苊献诱J(rèn)為怎樣才能做到“王道之始”？要想“王道之成”還需采取哪些措施？（明確：“不違農(nóng)時，谷不可勝食也。數(shù)罟不入氵夸池，魚鱉不可勝食也。斧斤以時入山林，材木不可勝用也。谷與魚鱉不可勝食，材木不可勝用五畝之宅，樹之以桑，五十者可以衣帛矣。雞豚狗彘之畜，無失其時，七十者可以食肉矣。百畝之田，勿奪其時，數(shù)口之家，可以無饑矣。謹(jǐn)庫序之教，申之以孝涕之義，頒白者不負(fù)戴于道路矣。）這一小步的目的是想讓學(xué)生通過這些問題的解答，可以進(jìn)一步理清思路，掌握文的大概內(nèi)容。
人教版高中語文必修3《老人與海》說課稿2篇
3、重要語句的理解“可是一個人并不是生來要給打敗的，你盡可把它消滅掉，可就是打不敗他。”解析：這是老人第一次回合之后的內(nèi)心獨白，也是此小說的核心精神，充分體現(xiàn)了老人桑地亞哥的生命理念。整句話可以分為兩部分來理解，前句告訴我們，人生活在自然與社會當(dāng)中，必不可少要面臨一些坎坷、磨難，這些磨難、坎坷完全可以造成軀體的消滅、消亡，這是人生命的脆弱性。后句，面對挫折，只要保持一種樂觀的精神，擁有一顆堅強的心靈，那么，人類執(zhí)著奮斗的精神將永不磨滅。4、象征主義題目是《老人與海》，而表明上，小說是寫一位老人及其在海上的經(jīng)歷，但實際上，老人的形象極具概括性，他已經(jīng)超越了一個人的存在，而成為了人生的一種象征。老人桑地亞哥就是“硬漢子”的代表，大海則是生命旅途的象征，鯊魚則是我們行走中的“強物”，厄運的象征。人的一生不可能一帆風(fēng)順，不經(jīng)歷風(fēng)雨，怎能見彩虹，走在人生路途中，不可避免我們都要遇到挫折，被厄運所阻撓，只有經(jīng)歷與“鯊魚”的較量，才能成為強者，唱出最美的歌。
人教版新課標(biāo)高中物理必修1探究加速度與力、質(zhì)量的關(guān)系教案2篇
三、制定實驗方案的兩個問題：1．怎樣測量（或比較）物體的加速度：引導(dǎo)學(xué)生思考、討論并交流。學(xué)生可能會提出下面的一些方案：方法一：測出初速度為零的勻加速直線運動的物體在 時間內(nèi)的位移 ，則 ；方法二：在運動的物體上安裝一條打點計時器的紙帶，根據(jù)紙帶上打出的點來測量加速度；方法三：測出兩個初速度為零的勻加速運動的物體在相同的時間內(nèi)發(fā)生的位移 、 ，則 ；方法四：測出兩個初速度為零的勻加速運動的物體在相同的位移內(nèi)所用的時間 、 ，則 ；2．怎樣提供并測量物體所受的恒力：教師提出：現(xiàn)實中，除了在真空中拋出或落下的物體（僅受重力）外，僅受一個力的物體幾乎是不存在的。然而，一個單獨的力作用效果與跟它大小、方向都相同的合力的作用效果是相同的，因此，實驗中力 的含義指物體所受的合力。以在水平軌道上用繩牽引小車加速運動為例，小車受到四個力的作用，即重力、支持力、繩的拉力和軌道對小車的摩擦力（當(dāng)物體運動的速度比較小時，我們可以忽略空氣的阻力）。
人教版新課標(biāo)高中物理必修1探究加速度與力、質(zhì)量的關(guān)系教案2篇
1．加速度與力的關(guān)系：實驗的基本思路是保持物體的質(zhì)量不變，測量物體在不同的力的作用下的加速度，分析加速度與力的關(guān)系。有了實驗的基本思路，接下去我們就要準(zhǔn)備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與力的數(shù)量關(guān)系，我們以 為縱坐標(biāo)、 為橫坐標(biāo)建立坐標(biāo)系，根據(jù)各組數(shù)據(jù)在坐標(biāo)系中描點。如果這些點在一條過原點的直線上，說明 與 成正比，如果不是這樣，則需進(jìn)一步分析。2．加速度與質(zhì)量的關(guān)系：實驗的基本思路是保持物體所受力不變，測量不同質(zhì)量的物體在該力作用下的加速度，分析加速度與質(zhì)量的關(guān)系。有了實驗的基本思路，接下去我們就要準(zhǔn)備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與質(zhì)量的數(shù)量關(guān)系，我們以 為縱坐標(biāo)、 為橫坐標(biāo)建立坐標(biāo)系，根據(jù)各組數(shù)據(jù)在坐標(biāo)系中描點，根據(jù)擬合的曲線形狀，初步判斷 與 的關(guān)系是反比例函數(shù)。再把 圖像改畫為 圖像，如果是一條過原點的斜直線，說明自己的猜測是否正確。
人教版高中政治必修4哲學(xué)史上的偉大變革說課稿（一）
2、講授新課：（35分鐘）通過教材第一目的講解，讓學(xué)生明白，生活和學(xué)習(xí)中有許多蘊涵哲學(xué)道理的故事，表明哲學(xué)并不神秘總結(jié)并過渡：生活也離不開哲學(xué)，哲學(xué)可以是我正確看待自然、人生、和社會的發(fā)展，從而指導(dǎo)人們正確的認(rèn)識和改造世界。整個過程將伴隨著多媒體影像資料和生生對話討論以提高學(xué)生的積極性。3、課堂反饋，知識遷移。最后對本科課進(jìn)行小結(jié)，鞏固重點難點，將本課的哲學(xué)知識遷移到與生活相關(guān)的例子，實現(xiàn)對知識的升華以及學(xué)生的再次創(chuàng)新；可使學(xué)生更深刻地理解重點和難點，為下一框?qū)W習(xí)做好準(zhǔn)備。4、板書設(shè)計我采用直觀板書的方法，對本課的知識網(wǎng)絡(luò)在多媒體上進(jìn)行展示。盡可能的簡潔，清晰。使學(xué)生對知識框架一目了然，幫助學(xué)生構(gòu)建本課的知識結(jié)構(gòu)。5、布置作業(yè)我會留適當(dāng)?shù)淖詼y題及教學(xué)案例讓同學(xué)們做課后練習(xí)和思考，檢驗學(xué)生對本課重點的掌握以及對難點的理解。并及時反饋。對學(xué)生在理解中仍有困難的知識點，我會在以后的教學(xué)中予以疏導(dǎo)。
