人教版新課標(biāo)高中地理必修2第二章第三節(jié)城市化教案
[補充]：鄭州是特大城市，我們對燈火通明的夜晚都有深刻的體會，我們都體會過光給他們帶來的好處，而對過多過亮的光帶來的危害則很少認(rèn)真地思考過，且光污染給都市人們和其他生物和環(huán)境帶來的不利影響也越來越大，所以，我在這兒給同學(xué)們補充光污染，目的是提醒他們要增強環(huán)保意識，要理解城市在建設(shè)過程中要減少城市各類活動對環(huán)境的污染；另外，隨著城市的不斷發(fā)展，還可能會產(chǎn)生新 的污染物。還培養(yǎng)了學(xué)生用發(fā)展的眼光來看世界。[思考]：如何降低城市化對地理環(huán)境產(chǎn)生的影響？[答]：發(fā)展生態(tài)城市，使人工環(huán)境和自然環(huán)境和諧統(tǒng)一起來。一方面在城市建設(shè)中，要發(fā)展低污染的節(jié)能建筑和綠色交通，減少城市各類活動對環(huán)境的污染；另一方面使城市景觀盡可能地與山、河、湖、海、植被等自然景觀保持協(xié)調(diào)，建立一種良性循環(huán)。

人教版高中地理選修3第二章第三節(jié)我國的旅游資源教案
2．對世界遺產(chǎn)的開發(fā)與保護原則——保護第一我國的世界文化遺產(chǎn)、世界文化與自然雙遺產(chǎn)具有時代性、不可再生性和不可替代性，我國的世界自然遺產(chǎn)都代表著某一類地質(zhì)地貌中最重要的歷史演化過程，展示了我國獨特的地質(zhì)地貌和生物資源。世界遺產(chǎn)的開發(fā)與保護之間存在一定的矛盾。我們必須堅持保護第一的原則。旅游開發(fā)只是世界遺產(chǎn)的功用之一，必須十分慎重，做到保護與開發(fā)協(xié)調(diào)統(tǒng)一，不能造成對世界遺產(chǎn)的任何破壞。案例②我國第一個世界文化與自然雙遺產(chǎn)——泰山通過學(xué)習(xí)案例②，了解到：①泰山不僅具有科學(xué)價值較高的地質(zhì)構(gòu)造，還具有多樣的地貌景觀，罕見的天象景觀，豐富的生物資源。泰山自古以來即被譽為名山，受到皇家和百姓的頂禮膜拜，各朝各代幾乎都進行過封禪行為，從而留下了深厚的歷史文化遺存，這一點跟其他名山相比是獨一無二的。
部編版六年級語文上冊《草原》教案
（1）思考：作者是按什么順序?qū)懙?？寫了哪些?nèi)容？明確：作者是按事情發(fā)展的先后順序來寫的。首先描述了一望無際的草原美景，使人感受到了一種境界美；接著又展示了主人歡迎遠方客人的隆重場面；最后把酒話別，用“蒙漢情深何忍別，天涯碧草話斜陽”來收束全文。（板書：初到草原——遠迎客人——熱情相見——盛情款待——聯(lián)歡話別）作者筆下的草原給你留下了什么印象？（學(xué)生討論、交流自己的印象，可與讀此文之前對草原的印象進行對比并探討。）
部編版語文九年級上冊《鄉(xiāng)愁》教案
【教學(xué)提示】教師可以示范分析其中兩個意象，注意引導(dǎo)學(xué)生把握普通事物之所以形成詩歌意象的原因，領(lǐng)悟詩歌意象的內(nèi)蘊意義。3．詩人在詩中運用了許多表修飾、限制的形容詞和數(shù)量詞，它們有什么特點？它們共同突出了詩歌中四個意象的什么特征？請你簡要說說它們在詩歌中的表達效果。明確：“一枚”“一張”“一方”“一灣”四個數(shù)量詞和“小小的”“窄窄的”“矮矮的”“淺淺的”四個形容詞，都是面積小重量輕的詞語。然而，郵票雖小，卻承載了母子深情；船票雖窄，卻聯(lián)系著夫妻之間濃濃的戀情；矮矮的墳?zāi)?，盛不下生死離情之痛；海峽雖淺，隔斷的思鄉(xiāng)哀愁卻是如此之深。這一系列限定修飾詞，都反襯了鄉(xiāng)愁的濃郁。目標(biāo)導(dǎo)學(xué)四：把握詩歌藝術(shù)特征探究：本詩除了在意象選取上頗費心思，在結(jié)構(gòu)藝術(shù)上也見出筆力。請同學(xué)們說說，本詩還具有哪些令你欣賞的藝術(shù)特征。
部編版語文九年級上冊《故鄉(xiāng)》教案
【分析楊二嫂形象】1．昔日的楊二嫂是怎樣的一個形象？明確：昔日被稱作“豆腐西施”，“擦著白粉”“終日坐著”，是一個安分守己的婦女形象。2．如今的楊二嫂是怎樣的形象？作者是從哪些方面刻畫的？明確：“凸顴骨”“薄嘴唇”“圓規(guī)”等肖像描寫，“尖利的怪聲”“大叫”“兩手搭在髀間”“貴人眼高”等動作和語言描寫，表現(xiàn)出了楊二嫂潑悍、放肆、尖刻的性格特征。討東西、造謠、塞手套又表現(xiàn)出她的自私、潑悍、愛貪小便宜。探究：作者塑造楊二嫂這一形象有什么作用？楊二嫂的形象是作者“悲哀”的源頭嗎？明確：楊二嫂的變化說明了辛亥革命后，城鎮(zhèn)小市民階層的貧困化，反映了當(dāng)時社會經(jīng)濟破產(chǎn)的廣度和深度。楊二嫂的變化，是不合理制度下的人性轉(zhuǎn)變，如果說閏土是“精神麻木”的狀態(tài)讓作者覺得“悲哀”，那么楊二嫂便是因為失去真善美的人性而使作者覺得“悲哀”。
部編版語文九年級上冊《沁園春》教案
提問(1)：“引”也是個領(lǐng)字，到底“引”出了哪些英雄人物？他們有什么共性？明確：秦始皇、漢武帝、唐太宗、宋太祖、成吉思汗。他們都是中國歷史上杰出的人物，是無數(shù)英雄中的佼佼者，都是雄才大略、戰(zhàn)功赫赫，對中國歷史的發(fā)展產(chǎn)生過巨大影響的人。提問(2)：對于這樣杰出的歷史人物，詞人用一個字對他們做了總的評價，請找出這個字，并說說這個字所包含的感情。明確：“惜”字。包含的感情：第一，惜中含褒?？隙ㄋ麄兪怯⑿廴宋?，同時也就肯定了中華民族是一個英雄輩出的偉大民族。第二，委婉地批評了他們?nèi)鄙傥闹危膶W(xué)才華欠缺。第三，他們的不足是時代、階級局限造成的。第四，表現(xiàn)了作者后來者居上的偉大氣概。提問(3)：作者對秦皇漢武、唐宗宋祖、成吉思汗的評價有區(qū)別嗎？從哪里可以看出來？明確：有區(qū)別，“略輸”“稍遜”二詞表現(xiàn)作者對秦皇漢武和唐宗宋祖在文治方面的不足只是略有批評，而“只識”一詞則表現(xiàn)出對成吉思汗是一種近乎嘲諷的評價。

人教版高中政治必修4第十二課實現(xiàn)人生的價值教案
有的學(xué)者還指出，要堅持集體主義還必須將集體主義的價值精神與社會主義市場經(jīng)濟的要求結(jié)合起來，批判地繼承計劃經(jīng)濟時代倡導(dǎo)的集體主義，合理地對其進行體系結(jié)構(gòu)的調(diào)整和內(nèi)容的更新，形成新的集體主義。與傳統(tǒng)的集體主義相比，這種新的集體主義應(yīng)具有如下兩個主要特點。其一，強調(diào)集體的出發(fā)點是為了維護集體成員的正當(dāng)個人利益。傳統(tǒng)的集體主義具有片面強調(diào)集體至上性、絕對性的弊端；新的集體主義必須依據(jù)社會主義市場經(jīng)濟的現(xiàn)實要求，將集體應(yīng)當(dāng)對個人承擔(dān)的義務(wù)加以科學(xué)的闡釋。真正的集體應(yīng)該維護各個集體成員的個人利益，實現(xiàn)組成集體的各個主體的自我價值。這種新型的集體主義是對社會主義市場經(jīng)濟條件下社會關(guān)系的真實反映，既與個人主義有本質(zhì)區(qū)別，也不同于傳統(tǒng)的集體主義。其二，要體現(xiàn)道德要求的先進性與廣泛性的統(tǒng)一。
人教版新課標(biāo)高中物理必修1牛頓第二定律教案2篇
1．這節(jié)課以實驗為依據(jù)，采用控制變量的方法進行研究。這一方法今后在電學(xué)、熱學(xué)的研究中還要用到。我們根據(jù)已掌握的知識設(shè)計實驗、探索規(guī)律是物體研究的重要方法。2．定義力的單位“牛頓”使得k=1，得到牛頓第二定律的簡單形式F=ma。使用簡捷的數(shù)學(xué)語言表達物理規(guī)律是物理學(xué)的特征之一，但應(yīng)知道它所對應(yīng)的文字內(nèi)容和意義。3．牛頓第二定律概括了運動和力的關(guān)系。物體所受合外力恒定，其加速度恒定；合外力為零，加速度為零。即合外力決定了加速度，而加速度影響著物體的運動情況。因此，牛頓第二定律是把前兩章力和物體的運動構(gòu)成一個整體，其中的紐帶就是加速度。四、評價方案及說明1、對科學(xué)知識與技能的評價要注重科學(xué)內(nèi)容的理解與應(yīng)用，而不是單純記憶。技能的評價目標(biāo)包括觀察技能、實驗技能等方面。對科學(xué)的技能的評價要盡量融合在科學(xué)探究過程的情景中。對科學(xué)知識的評價主要從兩方面，一是根據(jù)學(xué)生診斷性練習(xí)；二是通過學(xué)生作業(yè)反映學(xué)生掌握情況。
人教版高中語文必修3《馬嵬（其二）》教案2篇
結(jié)合歷史自古以來，江山美人歷來都是引無數(shù)英雄豪杰競折腰的，如果說英雄選擇了美人卻丟了江山，把所有罪名都歸結(jié)于“女人是禍水”。但是，紂王無道，和有了妲己有必然的聯(lián)系嗎？有人說妲己壞透了，壞透了的妲己如果不是取得紂王的信任是壞不起來的，紂王聽信了妲己的讒言，聽與不聽決定權(quán)在紂王，而不在妲己。強勢永遠在紂王一邊。再來看看西施和楊貴妃：西施是作為越國貢獻給吳國的供品來到吳王夫差的身邊的，楊貴妃更是先是李隆基的兒媳婦被看中而得寵的。所以，西施和楊貴妃這兩個可憐的女人根本沒有自己的獨立選擇，沒有獨立的愛情，如果沒有西施，就會有南施，或北施；如果沒有楊貴妃，就會有李貴妃，王貴妃，總之什么施，什么妃是不能少的，因為那是吳王和李隆基的需要。
