人教版高中語文必修3《琵琶行 并序》教案
9、在樂曲終了之后，詩人以“東船西舫悄無言，唯見江心秋月白”兩句結(jié)尾，這兩句作用如何？明確：詩人沒有直接寫聽者的熱烈反響以說明琵琶女技藝非凡和樂聲的感人至深，否則過于直白就不含蓄，不含蓄也就顯不出深沉了。用“東船西舫悄無言”的寂靜無聲，反襯“有聲”的音樂效果，可謂“此時無聲勝有聲”了。人們無聲地沉浸、陶醉在藝術(shù)的享受之中，那深深打動人的樂聲仿佛繚繞迂回耳際，不由得使詩人想到了自己浩茫的心事，引起情緒上的波瀾。在這片刻的沉寂中，只見一輪迷蒙的冷月蕩漾在江心的微波之中，它提醒詩人從樂聲中回到現(xiàn)實中來。這句景物描寫點染烘托了濃重的氛圍，與復(fù)雜的樂聲融為一體，共同表現(xiàn)了琵琶女與詩人息息相通的復(fù)雜情感，是那么的憂憤、哀怨凄楚、蒼涼，給整個音樂形象補足了畫龍點睛之筆。

(2)個性化的對話描寫。在三個事件的描述中，大段對話占了很大篇幅，有的情節(jié)干脆由對話來表達，許多對話形象地表現(xiàn)了人物的思想和性格，使我們?nèi)缏勂渎?，如見其人。先說藺相如，他在秦廷上的慷慨陳詞，有時語氣平和，謙恭有禮，使對方放松警惕；有時直言斥責(zé)，有理有據(jù)，雄辯折人；有時堅決表態(tài)，分析利害，暗示對方；有時怒不可遏，咄咄逼人?？傊?，詞鋒犀利，剛?cè)峒媸?，而又輕重恰當(dāng)，充分表現(xiàn)了他是一個熱愛祖國、不畏強暴、有智有勇，長于辭令的外交家。再說廉頗，在將相交歡事件中，他先前說的這一番話，表現(xiàn)了他的自高自大和心胸狹窄，非常符合武將廉頗的性格特點，后來寫他知過改過，負荊請罪時說：“鄙賤之人，不知將軍寬之至此也！”語言不多，坦誠直率，可敬可愛。（解說：對話描寫的分析，宜以學(xué)生為主，教師必要時適當(dāng)點撥。）

三．分析第三部分：1．夫妻贈詩表現(xiàn)了二人怎樣的心情？提示：崔鶯鶯告誡張生切勿忘記她；張生則發(fā)誓永無別戀。這充分展示了二人深厚的情誼。2．怎樣理解[耍孩兒]中的典故？提示：“紅淚”借王嘉《拾遺記》的典故，司馬青衫借白居易《琵琶行》的典故，表現(xiàn)主人公因離別而生的傷心之情?！安畡陲w去燕西歸”則用牛郎織女的典故表現(xiàn)兩人纏綿難舍的心情。3．[五煞]表明了主人公怎樣的心情？提示：對張生的生活的關(guān)心，千叮萬囑，真情自現(xiàn)。4．[二煞]中所用是幾個典故？這些典故的作用是什么？提示：三個典故，見課本。其作用是表明崔鶯鶯對張生的擔(dān)心。四．分析第四部分：1．[一煞]中再寫環(huán)境，其作用是否與先前所寫相同？提示：稍有不同，這里是表現(xiàn)崔鶯鶯目送張生遠去時那種凄愴悲苦的眷戀之情。以所見之物，寫內(nèi)心深藏之情。2．[收尾]中寫‘殘照’其含義是什么？提示：以“殘照”表現(xiàn)內(nèi)心的悵惘失意之情。
人教版高中語文必修4《李清照詞兩首》教案
2．【提問】《醉花陰》反映的是早年丈夫趙明誠游宦在外，作者一個人留在家中的生活狀況和內(nèi)心感受。對于這樣的“閨怨”題材，應(yīng)當(dāng)怎樣評價呢？【明確】作者作為一個封建時代的婦女，能夠坦率地表達出自己對于丈夫深深的思戀之情，描寫了閨中生活的孤獨寂寞，這在當(dāng)時乃是一種很大膽的行為。所以，有人批評說：李清照作詞是“無顧忌”地“肆意落筆”。其實，感情的充沛、真摯，敢于正面地展露自己的行為和內(nèi)心世界，正是她創(chuàng)作成功的重要原因之一，也正是她的詞最值得珍視的地方。3．【提問】古人常常愛用花比喻人之美貌，如“芙蓉如面柳如眉”，“人面桃花相映紅”等，而李清照卻說“人比黃花瘦”，這樣的比喻有什么豐富的內(nèi)涵？【明確】黃色的菊花不止外形上雅淡、清秀，與作者因相思而消瘦的體態(tài)相近，而且在菊花品格的傳統(tǒng)象征意義上，也酷似作者清高、淡泊的精神，這樣的比喻正比較恰切地反映了當(dāng)時作者由于離開丈夫而孤獨、愁悶的生活狀態(tài)和內(nèi)心情感。

三、第三階段。課后感悟與收獲１、讓學(xué)生以“走向?qū)W習(xí)型社會”為題，將在收集與整理、展示與交流兩個環(huán)節(jié)中獲得的體驗和感悟，以心得體會的形式寫一篇小論文。２、辦一期專欄或黑板報，將優(yōu)秀小論文作集中展示與交流。（進行理論總結(jié)，將實踐與理論相結(jié)合，讓科學(xué)理論更好地指導(dǎo)實踐。充分挖掘?qū)W生潛力，增強學(xué)生的自信）［評析］新課程理念之一就是政治課不應(yīng)只局限于課堂上的教與學(xué)。把綜合探究課與研究性學(xué)習(xí)相結(jié)合，不失為一種有益的嘗試。傳統(tǒng)的學(xué)習(xí)方式把學(xué)習(xí)建立在客觀性、受動性、依賴性的基礎(chǔ)上，把學(xué)生看成一個沒有感情的接受容器，這種學(xué)習(xí)會窒息學(xué)生的思維和智力，成為學(xué)生發(fā)展的障礙。單元探究活動的開展就是要轉(zhuǎn)變學(xué)生的學(xué)習(xí)方式，關(guān)注學(xué)生的學(xué)習(xí)過程，使得探究過程成為學(xué)生發(fā)現(xiàn)問題、提出問題、分析問題、解決問題的過程，培養(yǎng)學(xué)生的創(chuàng)新精神和實踐能力。本教案的第一階段充分發(fā)揮了學(xué)生的主動性。
人教版高中政治必修3體味文化教案2篇
3、文化是人們的一種素養(yǎng)（1）人的文化素養(yǎng)是在社會生活、實踐中形成的。每個人所具有的文化素養(yǎng)，不是天生的，而是通過對社會生活的體驗，特別是通過參與文化生活、接受知識文化教育而逐步培養(yǎng)出來的。文化素養(yǎng)的形成，離不開生活、實踐和教育。人們在社會實踐中創(chuàng)造和發(fā)展文化，也在社會生活中獲得和享用文化。（2）人的文化素養(yǎng)表現(xiàn)在日常言行中。教師活動：引導(dǎo)學(xué)生閱讀教材7頁“公交車漫畫”材料，并思考所反映的問題學(xué)生活動：積極思考并討論問題教師點評：人們的精神活動離不開物質(zhì)活動，人們的文化素養(yǎng)總是要通過他在日常生活中的言行、在社會實踐活動中的表現(xiàn)等表現(xiàn)出來。我們通過觀察人們的社會行為，就可以從中透視人們的精神世界和精神生活。4、文化的傳承和發(fā)展離不開物質(zhì)載體。社會文化和精神產(chǎn)品離不開物質(zhì)載體，一個時代的文化和精神產(chǎn)品，往往是這一時代社會發(fā)展軌跡的反映。
