The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life.

Let's enjoy the fun of music!Thanks again for your attention!

二、文本解讀方法點(diǎn)撥研讀課文第三、第四段。要求:師范讀,生輕聲跟讀,然后生齊讀。方法:第三段秦統(tǒng)一天下前,應(yīng)用較強(qiáng)的語(yǔ)勢(shì)讀出,充分渲染塑造一個(gè)“威加海內(nèi)”的帝王形象。統(tǒng)一天下之后,秦王朝至此已達(dá)頂峰,這意味著從此轉(zhuǎn)入守勢(shì)。這段文字義正詞嚴(yán),充分揭露了秦的暴虐無(wú)道,故誦讀應(yīng)有“聲討”之勢(shì)。末句“天下已定”總承以上內(nèi)容,其后應(yīng)有較長(zhǎng)停頓,然后轉(zhuǎn)入敘秦始皇的心態(tài),用以反襯下文滅亡之速,讀時(shí)須有嘲諷意,突出“自以為”“萬(wàn)世之業(yè)”等詞語(yǔ)。第四段起首“始皇既沒(méi),余威震于殊俗”兩句,暗示民心不服,人人自危,宜用從容、沉著的語(yǔ)調(diào)讀出。“然陳涉甕牖繩樞之子……”急轉(zhuǎn)直下,稍作停頓,以下先抑(“陳涉”至“之富”)后揚(yáng)(“躡足”至段末)宜讀出對(duì)比情調(diào)。末句敘事結(jié)束全篇,要讀得沉著、有力。三、信息篩選學(xué)生自譯課文(一)學(xué)生參照文下注釋?zhuān)谧g第三、四段,遇有疑難則作好相應(yīng)標(biāo)記,為討論做好準(zhǔn)備。
竇娥的三樁誓愿明明是幻想,卻偏偏寫(xiě)成現(xiàn)實(shí),明明是不合理的偏偏寫(xiě)成合理的,這說(shuō)明了什么?明確:這說(shuō)明在當(dāng)時(shí)的歷史條件下,除了乞求天地鬼神申訴冤屈以外,沒(méi)有別的辦法,作者采用這種浪漫主義的表現(xiàn)手法,一是表明社會(huì)的腐敗黑暗,二是刻畫(huà)竇娥強(qiáng)烈的反抗精神,三是表達(dá)人民要懲治邪惡的愿望?!吧贰本褪墙Y(jié)尾的曲牌,為什么關(guān)漢卿要把“煞”分成[二煞][一煞][煞尾]三個(gè)曲牌呢?明確:說(shuō)明蓄積在竇娥胸中的怒火再也無(wú)法控制,猶如地下巖漿,沖向決口。也說(shuō)明劇作家意猶未盡,他要把竇娥的無(wú)辜受害,要把人們對(duì)竇娥的同情,要把人們對(duì)統(tǒng)治者的憤恨表現(xiàn)得痛痛快快,淋漓盡致。于是在結(jié)尾處一波三折,把高潮推向頂峰。《竇娥冤》中有兩句唱詞,兩個(gè)牌文本不同,試分析其優(yōu)劣。《古名家雜劇》本:地也,你不分好歹難為地;天也,我今日負(fù)屈銜冤哀告天。
【教學(xué)過(guò)程】一、介紹作者沈從文先生(1902~1988),現(xiàn)代作家、歷史文物研究學(xué)者。原名沈岳煥,筆名小兵、懋琳、休蕓蕓等。湖南鳳凰(今屬湘西土家族苗族自治州)人。1926年出版第一本創(chuàng)作集《鴨子》,有7O余種作品集,被人稱(chēng)為多產(chǎn)作家。主要代表作有:短篇小說(shuō)《丈夫》、《貴生》、《三三》,長(zhǎng)篇小說(shuō)《邊城》、《長(zhǎng)河》,以反映湘西下層人民生活的作品最具特色。他的創(chuàng)作表現(xiàn)手法不拘一格,文體不拘常例,故事不拘常格,嘗試各種體式和結(jié)構(gòu)進(jìn)行創(chuàng)作,成為現(xiàn)代文學(xué)史上不可多得的“文體作家”。在文學(xué)態(tài)度上,沈從文先生一直堅(jiān)持自由主義立場(chǎng),堅(jiān)持文學(xué)要超越政治和商業(yè)的影響。1948年沈從文先生受到了左翼文化界猛烈批判,郭沫若斥責(zé)沈從文先生:“一直是有意識(shí)的作為反動(dòng)派而活動(dòng)著”。下半生從事文物、工藝美術(shù)圖案及物質(zhì)文化史的研究工作。1978年調(diào)中國(guó)社會(huì)科學(xué)院歷史研究所任研究員,致力于中國(guó)古代服飾及其他史學(xué)領(lǐng)域的研究。于1980年應(yīng)邀赴美國(guó)講學(xué),并進(jìn)入諾貝爾文學(xué)獎(jiǎng)的終審名單。
【教學(xué)內(nèi)容及步驟】第一課時(shí)一、簡(jiǎn)介并導(dǎo)入:這篇小說(shuō)是發(fā)表于《青年文學(xué)》1982年第五期,并獲得1982年全國(guó)最佳短篇小說(shuō)獎(jiǎng)的小說(shuō)。作者鐵凝,1957年生,河北趙縣人,現(xiàn)任中國(guó)作家協(xié)會(huì)理事,發(fā)表中短篇小說(shuō)60余篇,出版有短篇小說(shuō)集《夜路》,中短篇小說(shuō)集《沒(méi)有紐扣的紅襯衫》《鐵凝小說(shuō)集》。她以一個(gè)女作家的敏銳、細(xì)膩的藝術(shù)感受力,真摯美好的情致,對(duì)生活素材獨(dú)到的發(fā)掘和精巧提取,語(yǔ)言清朗睿智,作品蘊(yùn)涵深摯,質(zhì)樸優(yōu)美。這篇小說(shuō)寫(xiě)的是一群以香雪為代表的山村少女對(duì)開(kāi)進(jìn)深山的火車(chē)表現(xiàn)出來(lái)的喜怒哀樂(lè),以此折射出受現(xiàn)代文明沖擊的農(nóng)村蹣跚前進(jìn)的身影。小說(shuō)借臺(tái)兒溝的一角,寫(xiě)出了改革開(kāi)放后中國(guó)從歷史的陰影下走出,擺脫封閉、愚昧和落后,走向開(kāi)放、文明與進(jìn)步的痛苦與喜悅,構(gòu)思巧妙,表述獨(dú)特,語(yǔ)言精美。小說(shuō)主要通過(guò)哪幾個(gè)故事情節(jié)表現(xiàn)的呢?
【教學(xué)目標(biāo)】Ⅰ、學(xué)習(xí)理解詩(shī)歌語(yǔ)言的暗示性特質(zhì)。Ⅱ、根據(jù)詩(shī)歌語(yǔ)言的特質(zhì),進(jìn)行遷移,領(lǐng)略詩(shī)歌的精妙之處,給同學(xué)如何鑒賞詩(shī)歌提供實(shí)感。㈠、導(dǎo)入:各位同學(xué),有個(gè)成語(yǔ)叫"一字千金"。對(duì)我而言,第一次領(lǐng)略到一個(gè)字的分量,是在小學(xué)三年級(jí)的時(shí)候,一次作文評(píng)析課上。當(dāng)時(shí)我對(duì)自己的文章充滿(mǎn)了期待,希望能得到老師的贊賞。記得老師進(jìn)來(lái)后的第一句話(huà)是"有一篇文章,我就沖它用了一個(gè)字,我給它打95分。打這樣的高分,對(duì)我來(lái)說(shuō),是極為難得的。"同學(xué)都充滿(mǎn)了好奇,老師接著說(shuō)"這個(gè)字就是一個(gè)'悟'字。我們的同學(xué)都說(shuō)我學(xué)到了,我明白了,我懂得了一個(gè)道理,而這位同學(xué)卻用了一個(gè)'悟'字,難能可貴。"這篇文章不是我的,在羨慕的同時(shí),一個(gè)字在文章中的分量就深深的刻在了我的心上。文學(xué)作品中,一個(gè)字精妙與否,足以決定作品是流光溢彩,還是黯然失色。尤其是我們的古典詩(shī)詞,用簡(jiǎn)短的幾個(gè)字,造就的卻是豐富的情感與博大的意境。讀后滿(mǎn)口余香,卻是妙處難與君說(shuō)。這跟詩(shī)歌的語(yǔ)言是密不可分的。今天,我們就通過(guò)《說(shuō)"木葉"》一文,對(duì)中國(guó)古典詩(shī)詞語(yǔ)言特質(zhì)作一番探幽。
⒈作者是如何寫(xiě)洪州的地理風(fēng)貌的?突出了什么特點(diǎn)?明確:“豫章故郡,洪都新府?!报D―歷史久遠(yuǎn)“星分翼軫,地接衡廬”――界域遼闊?!敖笕鴰搴匦U荊而引甌越”――地勢(shì)宏偉2.作者怎樣寫(xiě)參加宴會(huì)的人物,照應(yīng)了前文的哪個(gè)詞語(yǔ)?明確:作者在寫(xiě)參加宴席人物時(shí),用了“雅望”“懿范”“勝友”“高朋”“騰蛟起鳳”“紫電清霜”等詞語(yǔ),極盡人物的文韜武略,照應(yīng)了前文的“俊采”一詞。3.文章開(kāi)始不寫(xiě)樓臺(tái),不寫(xiě)宴會(huì),而先寫(xiě)地勢(shì)與人物,這樣寫(xiě)有何好處?明確:文章借用鋪陳的手法,歷敘界域之大,地勢(shì)之雄,物產(chǎn)豐富,人才俊美,既渲染了和樂(lè)的氛圍、宴會(huì)的高雅,同時(shí)也緊扣照應(yīng)了題目《秋日登洪府滕王閣餞別序》7.小結(jié):本段略寫(xiě)洪州的地理風(fēng)貌,極寫(xiě)滕王閣的無(wú)限壯美,和周?chē)h(huán)境的超凡脫俗,以及閣中如云高朋的文才武略。這樣寫(xiě),既初步寫(xiě)出了滕王閣的不同凡響,又為后文詳寫(xiě)做好了鋪墊。
一、明確目標(biāo)1.引導(dǎo)學(xué)生熟讀課文,理清文章的論述線(xiàn)索,抓住作者的主要觀點(diǎn);2.通過(guò)學(xué)習(xí),了解有關(guān)數(shù)學(xué)文化的一些知識(shí);3.引導(dǎo)學(xué)生悉心體會(huì)作者對(duì)數(shù)學(xué)源頭的溯訪(fǎng),感受其令人信服的推理能力和獨(dú)特的語(yǔ)言魅力;二、整體感知1.導(dǎo)入新課"屈指可數(shù)""彈指一揮見(jiàn)",手指在生活中的計(jì)數(shù)功能,直接催生了數(shù)學(xué)這門(mén)科學(xué),丹齊克的《指印》為我們揭開(kāi)了這二者的關(guān)系(板書(shū)課題)。2.作者及相關(guān)背景介紹丹齊克(1884-1956),原籍立陶宛,曾在巴黎大學(xué)求學(xué)。1910年去美國(guó),入美國(guó)國(guó)籍,先后在哥倫比亞大學(xué)、約翰·霍普金斯大學(xué)、馬里蘭大學(xué)講授數(shù)學(xué)。三、重點(diǎn)、難點(diǎn)的學(xué)習(xí)與目標(biāo)達(dá)成過(guò)程1.感知課文,明確本文的整體寫(xiě)作思路。(1)學(xué)生讀課文,整理文章的結(jié)構(gòu)脈絡(luò)。(2)小組交流討論。
節(jié)選部分結(jié)構(gòu):節(jié)選自第二幕,主要寫(xiě)周樸園與魯家母子的對(duì)話(huà),分兩部分。第一部分:三十年后周樸園和侍萍再次相見(jiàn)。第一層:侍萍以敘述別人故事的口吻,揭露周樸園的罪惡,訴說(shuō)自己的遭遇。──寫(xiě)他們過(guò)去的矛盾第二層:通過(guò)周樸園態(tài)度的變化,暴露他的偽善面目,表現(xiàn)侍萍這個(gè)勞動(dòng)?jì)D女的階級(jí)本色。──寫(xiě)他們現(xiàn)在的矛盾第二部分:周樸園與魯大海父子、侍萍與周萍母子見(jiàn)面。通過(guò)周樸園和魯大海的激烈沖突,揭露周樸園壓榨工人的罪行,反映工人階級(jí)的反抗斗爭(zhēng)。分段依據(jù):第一部分從家庭生活方面來(lái)揭露周樸園;第二部分從社會(huì)生活方面來(lái)揭露周樸園。為了使周魯兩家三十年的新仇舊恨集中在一幕戲中得到反映,作者靈活地運(yùn)用了“回顧”的方法,把歷史和現(xiàn)實(shí),過(guò)去和現(xiàn)在緊緊聯(lián)系起來(lái)了,用以刻畫(huà)人物性格,推動(dòng)劇情發(fā)展。
★教學(xué)總結(jié):(1)我國(guó)衣著服飾變化的三大階段第一階段(鴉片戰(zhàn)爭(zhēng)后到新中國(guó)的建立):這一階段的階段特征為中式與西式、傳統(tǒng)和現(xiàn)代服飾并存男裝:長(zhǎng)袍馬褂、西裝、中山裝 女裝:旗袍(新式與舊式)第二階段(新中國(guó)建立后到十一屆三中全會(huì)):這一時(shí)期由于政治上的影響,階段特征為衣著樸素,與革命相關(guān)的服飾成為主流男裝:列寧裝、中山裝、綠軍裝女裝:列寧裝、布拉基、綠軍裝第三階段(十一屆三中全會(huì)后):階段特征為與世界接軌,異彩紛呈;具體表現(xiàn)在,服飾由最基本的防寒保暖向美觀大方轉(zhuǎn)變,各種款式的服裝層出不窮現(xiàn)在的服裝是色彩鮮艷、款式多樣,什么牛仔服、休閑服、西裝、T恤衫、晚禮服,真是不勝枚舉。每年服裝的流行色、流行款式不斷改變,大街上的姑娘和小伙子永遠(yuǎn)領(lǐng)導(dǎo)著時(shí)裝新潮流。模特表演、模特廣告和模特大賽已成為人們穿著方面不可缺少的內(nèi)容。
【教學(xué)方法】本節(jié)課的教學(xué)知識(shí)點(diǎn)比較瑣碎,學(xué)生學(xué)習(xí)和理解起來(lái)有較大的困難。教師在并結(jié)合教材中所引的文獻(xiàn)資料給予必要的點(diǎn)撥,并依據(jù)教材,并在此基礎(chǔ)上拓展教材引用有關(guān)材料,擴(kuò)展學(xué)生的思維,用思考題的形式,有機(jī)地將教材的重點(diǎn)、難點(diǎn)知識(shí)串聯(lián)起來(lái),注意培養(yǎng)學(xué)生史論結(jié)合、論從史出的良好的歷史學(xué)習(xí)品質(zhì)?!緦?dǎo)入新課】秦始皇統(tǒng)一中國(guó)后,繼承了商鞅變法的成果和實(shí)踐了韓非子的理論,創(chuàng)立了封建專(zhuān)制主義中央集權(quán)的政治制度,即皇帝制、中央官制和郡縣制,把專(zhuān)制主義的決策方式和中央集權(quán)的政治制度有機(jī)結(jié)合起來(lái)。秦始皇首創(chuàng)的專(zhuān)制主義中央集權(quán)的政治體制為我國(guó)延續(xù)兩千多年的封建社會(huì)選擇了政治體制的基本模式。西漢王朝建立后,劉邦承襲了秦始皇所開(kāi)創(chuàng)的統(tǒng)一的封建專(zhuān)制主義中央集權(quán)制。通過(guò)綜合概述上節(jié)課內(nèi)容,導(dǎo)入新課。
提問(wèn):城市環(huán)境污染源主要有哪些?有些同學(xué)基本同意自行車(chē)多是加劇南京空氣污染的間接原因,你同意他們的觀點(diǎn)嗎?在學(xué)生回答的基礎(chǔ)上,教師進(jìn)行歸納小結(jié):工業(yè)和交通是城市環(huán)境的主要污染源。而自行車(chē)是一種綠色交通工具,既環(huán)保又經(jīng)濟(jì)。只有當(dāng)它在某些機(jī)動(dòng)車(chē)和非機(jī)動(dòng)車(chē)不分的地段,影響車(chē)輛行駛速度的時(shí)候,它才可能成為加劇空氣污染的間接原因。問(wèn):那我們針對(duì)交通工具對(duì)環(huán)境造成的影響,有什么解決方法嗎?歸納小結(jié):? 實(shí)施減少汽車(chē)尾氣污染的技術(shù)措施? 加強(qiáng)道路綠化? 合理規(guī)劃城市道路,提高車(chē)速? 制定相關(guān)法規(guī)嚴(yán)禁各種車(chē)輛違規(guī)鳴喇叭? 在噪音嚴(yán)重的地區(qū)設(shè)置先進(jìn)的隔音設(shè)施總結(jié):通過(guò)前面的分析我們知道了自行車(chē)過(guò)多并不是造成北京交通擁擠的主要原因,但自行車(chē)多并且不遵守交通規(guī)則的確是造成交通擁堵的一個(gè)原因。從這方面來(lái)講,在一些混合車(chē)道地段,自行車(chē)是造成空氣污染加劇的間接原因。那么在北京到底是應(yīng)該鼓勵(lì)自行車(chē)的發(fā)展還是限制自行車(chē)的發(fā)展呢?
生1:公平性原則——同代人之間要公平,代際之間、人類(lèi)與其他生物種群之間、不同國(guó)家與地區(qū)之間也要公平。生2:持續(xù)性原則——地球的承載力是有限的,人類(lèi)的經(jīng)濟(jì)活動(dòng)和社會(huì)發(fā)展必須保持在資源和環(huán)境的承載力之內(nèi)。生3:共同性原則——發(fā)展經(jīng)濟(jì)和保護(hù)環(huán)境是全世界各國(guó)共同的任務(wù),需要各國(guó)的共同參與。同時(shí),地球作為一個(gè)整體,地區(qū)性問(wèn)題往往會(huì)變?yōu)槿蛐詥?wèn)題,所以地區(qū)的決策和行動(dòng),應(yīng)有助于實(shí)現(xiàn)全球整體的協(xié)調(diào)?;顒?dòng)與探究:2·閱讀下面一篇新聞報(bào)道,你認(rèn)為“給蛇讓道”有沒(méi)有必要?答:有必要·人類(lèi)在森林區(qū)內(nèi)修筑公路,已經(jīng)侵占和破壞了蛇的生存環(huán)境,如果再不對(duì)蛇的遷移進(jìn)行保護(hù),蛇數(shù)量的減少以至滅絕將不可避免。這種做法體現(xiàn)了可持續(xù)發(fā)展的公平性原則和共同性原則。3·用可持續(xù)發(fā)展的觀念作為衡量標(biāo)準(zhǔn),對(duì)下列觀點(diǎn)作出評(píng)價(jià)。(1)人類(lèi)有義務(wù)保護(hù)地球上所有的物種,人類(lèi)的發(fā)展不應(yīng)該危及其他物種的生存。答:正確。符合可持續(xù)發(fā)展的公平性原則。
