三、想象畫面,把握意境1.指導(dǎo)想象學(xué)習(xí)陶淵明的《歸園田居》我們腦海中自然會出現(xiàn)一幅幅的畫面,比如他歸家后的生活場景,我們會想象“榆柳”是如何遮蔽房屋的,而“桃李”又是如何摘種在房前的。我們會想象村落是如何在薄霧中若隱若現(xiàn)的,想象炊煙是如何裊裊升起的?!渡娼绍饺亍芬辉娭挥?句話,更需要我們展開想象,去構(gòu)畫場景,這樣才能深入詩歌,體會到詩歌的味道。2.學(xué)生想象要求學(xué)生閉目想象1分鐘。3.學(xué)生展示想象結(jié)果(抽三四個學(xué)生回答即可)4.老師指導(dǎo)糾正學(xué)生想象不合理之處。要注意的地方:“江”可能學(xué)生會想象成小溪流、小池塘。“蘭澤”可能學(xué)生理解成“湖泊”。注意字詞“還顧”“漫浩浩”中隱含的情感,注意“離居”中流露的愁怨。5.時間允許的話,老師讀自己的下水作文。
一個世紀前,一位了不起的美國人簽署了奴隸解放宣言,而我們今天就站在他的塑像下面。對于千千萬萬身受不公正待遇之苦的黑奴來說,這份劃時代的文件,是一座光芒萬丈的希望燈塔,是結(jié)束他們被束縛之漫漫長夜的快樂黎明。我有一個夢,有朝一日在喬治亞州的丘陵地帶,奴隸的后代與奴隸主的后代,將能夠兄弟般地相處。我有一個夢,有朝一日甚至密西西比州,這個充滿不平與壓迫的州,將轉(zhuǎn)化成一片自由與公正的綠洲。我有一個夢,我的四個孩子,有朝一日將可以生活在這樣一個國度里:在此人們不是根據(jù)他們的膚色,而是根據(jù)他們的品行來衡量他們。我今天有一個夢!我有一個夢,有朝一日在阿拉巴馬州,盡管目前有許多惡毒的種族主義者,盡管州長叫嚷著要與聯(lián)邦政府對抗,有朝一日在阿拉巴馬州,黑人孩子與白人孩子將會像兄弟姊妹那樣親密無間。
全班齊讀第五段內(nèi)容。請一位同學(xué)分析,接著讓這位同學(xué)按他分析的讀一遍。3、4兩自然段的平緩之后,第5段作者的情感再次抬升。為了滿足這種情感的張揚,作一口氣連用了四個排比句式“現(xiàn)在是……時候”,一方面這是情感發(fā)泄的需要,另一方面這種排山倒海的語勢也加強了內(nèi)容的表達,極強地突出了現(xiàn)實為自由、平等而戰(zhàn)的重要性。四、學(xué)會演講我們剛才細讀了課文,但讀和講是有區(qū)別的。所謂演講,是一門語言藝術(shù),它的主要形式是“講”,即運用有聲語言并追求言辭的表現(xiàn)力和聲音的感染力;同時還要輔之以“演”,即運用面部表情、手勢動作、身體姿態(tài)乃至一切可以理解的態(tài)勢語言,使講話“藝術(shù)化”起來,從而產(chǎn)生一種非凡的藝術(shù)魅力。那么,接下來就假設(shè)一下假如你是馬丁·路德·金,你會怎樣去講這篇演講辭。
四、品味詩歌藝術(shù)1、詩人是如何表現(xiàn)其品質(zhì)的?運用了什么修辭手法?產(chǎn)生了怎樣的表達效果?明確:詩句“扈江離與辟芷兮,紉秋蘭以為佩”很好地體現(xiàn)了詩人光輝俊潔的人格。用“江離”“辟芷”“秋蘭”三種香草來裝飾自己,比喻自己,極其生動形象地表現(xiàn)了詩人自己美好的精神世界,使詩歌充滿了浪漫主義氣息。2、《離騷》中作者常以“香草”、“美物”來比喻自己、賢士和君王,并表達政治理想,這是《離騷》的一大藝術(shù)特色,這種方法叫做“移情法”,即不直接說出自己想說的話,而是把它寄寓于某一物上,也就是“移情于物”,這種方法在古典詩詞中廣泛運用,在政治不清明的時代,借用“移情”,可言難言之語,抒難抒之情。請找出相關(guān)的詩句,說說詩人是怎樣運用這些比喻來表達政治理想的。
教學(xué)設(shè)想:本節(jié)課的主題是“生命之綠,璞玉心靈”,用圈點批注法解讀愛綠的感情,讓學(xué)生在批注中明確“綠”的象征意義,而不只是結(jié)論的傳遞。同時借助于閱讀、感受和理解把握作者對綠的認識是不斷升華的,由一般對生命希望之綠的喜愛,到與綠交往后被它的不畏強暴,永遠向陽的精神所折服,最后在特定的時代背景下綠在作者的心目中已經(jīng)成了我們民族不屈精神的象征。讓學(xué)生評中求解,評中悟情,評中明理,評中品味。教學(xué)進程:一、導(dǎo)語上節(jié)課我們學(xué)習(xí)了朱自清的《綠》,初步了解了讀書動筆的基本方法,這節(jié)課我們繼續(xù)用圈點批注的方法來學(xué)習(xí)陸蠡的散文《囚綠記》。二、釋題師:看標題,囚綠之“綠”在文中具體指什么?(一株常春藤)“囚”就是囚禁的意思,那題目就是記述囚禁綠色常春藤的經(jīng)過。三、圈點、把握情節(jié)作者為什么要囚綠呢?文中除了寫“囚綠”之外,還寫了哪些有關(guān)綠的意念和行動?帶著這樣的質(zhì)疑用自己喜歡的方式朗讀課文,請同學(xué)們?nèi)c出疑難字詞,或結(jié)合書下注釋,或同學(xué)合作解決,解決不了的,可提出來我們共同解決。標注段落節(jié)次。勾畫出表現(xiàn)作者對綠意念和行動的句子。
【教學(xué)設(shè)想】一、選題設(shè)想《巴黎圣母院》是雨果的代表作,無論從思想內(nèi)容還是藝術(shù)風格都有明顯的浪漫主義特征:奇異曲折、扣人心弦的故事情節(jié);妙趣橫生、別出心裁的奇遇巧合;強烈鮮明的美丑、善惡對比;豐富生動、珠璣迸發(fā)、富有哲理意味的語言。通過導(dǎo)讀,來消除學(xué)生對外國名著的畏難情緒,增加學(xué)生課外閱讀的興趣和信心;讓學(xué)生整體把握作品,窺一斑而識全豹,讓學(xué)生高屋建瓴,了解其旨意,以極為精確而又充滿意蘊的文字,對名著的概述及精要部分做了介紹;引導(dǎo)學(xué)生自主探究,交流合作,培養(yǎng)學(xué)生的獨立思考的學(xué)習(xí)慣,指點進行名著閱讀的門徑。作為導(dǎo)讀課,教師應(yīng)注意不可“越位”,在學(xué)生學(xué)習(xí)的過程中,教師的“導(dǎo)”固然重要,學(xué)生的“讀”更不可或缺,應(yīng)避免以“導(dǎo)讀”來代替名著閱讀。因此,《巴黎圣母院》的教學(xué)定位為基于課內(nèi),面向課外,以求達到以學(xué)帶讀,以讀促學(xué)的目的。
教學(xué)過程:一、導(dǎo)語毛澤東在《沁園春雪》俯視封建君王“惜秦皇漢武。。。只識彎弓射大雕?!钡绻麣v史上只有一個人可以與他相提并論,這個人只能是魏武帝曹操?!皾L滾長江東逝水,浪花淘盡英雄。是非成敗轉(zhuǎn)頭空,青山依舊在,幾度夕陽紅?!保ā度龂萘x》卷首詞)在歷史的大浪淘沙中,有多少英雄能夠經(jīng)得起歷史的千淘萬漉而流芳百世呢?曹操應(yīng)該是三國時代留下了濃重一筆的人物。老師總結(jié),并啟發(fā)他們?nèi)ヂ?lián)系:我們學(xué)過他的《觀滄?!贰皷|臨碣石,以觀滄?!边€有《龜雖壽》“神龜雖壽,猷有竟時。老驥伏櫪,志在千里;烈士暮年,壯心不已?!薄肚嗝分鬄⒄撚⑿邸分性退娺^,《三國演義》電視劇播出后,大家和他也就頻頻見面了?!度龂萘x》第48回“宴長江曹操賦詩”中,赤壁之戰(zhàn)前夕,曹操和眾部將一起狂飲,他四顧空闊,心中大喜,與諸將講述自己希望收服江南的雄心壯志。

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves.

The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1.

這兩章是對戰(zhàn)爭場面的描寫。寫的是戰(zhàn)車、戰(zhàn)馬、象弭、魚服以及士兵的勞累奔波、饑渴難當,通過這些具體生動的細節(jié)描寫來展現(xiàn)戰(zhàn)爭生活的圖景。而沒有寫戰(zhàn)場上的刀光劍影、廝打拼殺,但戰(zhàn)爭的殘酷已可想見。4“昔我往矣,楊柳依依。今我來思,雨雪霏霏”被視為情景交融的佳句。清人王夫之在論《詩經(jīng)·小雅·采薇》這兩句時說:“以樂景寫哀,以哀景寫樂,一倍增其哀樂?!闭?wù)勀愕目捶āR灰酝糁撘r眼前之實,以出征之樂襯內(nèi)心之思親之悲痛;二“楊柳依依”與“雨雪霏霏”對比,突出不勝今昔之感;三大雪交加,饑渴難當,情境實悲,以哀景寫哀情。四、交流延伸1寫一首詩或一段文字表達你對“鄉(xiāng)愁”的新的體驗。在全班交流。2課后搜集更多的表現(xiàn)鄉(xiāng)情的詩歌散文作品,將你最感動的一篇拿到班上與同學(xué)分享感受。
【設(shè)計思想】詩歌教學(xué)的關(guān)鍵是感受詩景,體味詩情,領(lǐng)悟詩意,在此基礎(chǔ)上孕育理解能力、鑒賞能力和審美情感。詩景、詩情、詩意均由文字來承載,把握文字組合的張力,是讀詩賞詩的抓手。杜甫的詩歌素以煉字精深、涵蓋深遠著稱,以《登高》而言,往往淡淡一字,平平一語,便籠大千于方寸,縮古今于一瞬。故細讀文本,咀嚼字句,便是賞景、悟情、會意的基本路徑。其次,不朽名作的特點是寄寓深廣,古今評價甚多,見仁見智,不一而足。這正是培養(yǎng)學(xué)生問題意識、探究意識的極好憑借。第三,詩為語言之精華,是詩人心里涌出的情感之流。誦讀乃賞詩之要著,精心感悟之時,設(shè)身處地,心惟口誦,是理解詩意的關(guān)鍵一步?;谑?,筆者作如下同課異構(gòu),殊途同歸?!窘虒W(xué)目標】1.理解本詩所繪之景、所抒之情及繪景、抒情之法。2.學(xué)會用意象疊加法、字句推敲法、誦讀體驗法等欣賞詩歌。3.感受杜甫心系蒼生、情寄邦國、憂國憂民、兼濟天下的博大情懷。
(一)導(dǎo)入[以視頻欣賞導(dǎo)入]同學(xué)們,剛才欣賞的是大家熟悉、喜歡的電視劇《亮劍》中的精彩片段——李云龍論述什么是“亮劍”精神?同學(xué)們聽后覺得好不好?牛不牛?“亮劍”精神簡單理解就是敢于與強大的敵人(對手)做斗爭,無論對手多么強大,都要滿腔勇氣和信心,永不放棄、永不言敗,要敢于亮劍……今天我們一起來學(xué)習(xí)世界100部著名文學(xué)作品之一、美國里程碑式30部文學(xué)作品之一的世界名著——海明威的《老人與?!?,看看主人公桑提亞哥“硬漢”性格和李云龍“亮劍”精神有么相似的地方。(請同學(xué)們翻到課文,課件顯示課題《老人與海》)(二)走進作者:請同學(xué)們自己談收集到的有關(guān)海明威的資料,然后教師梳理出下列核心內(nèi)容識記:(課件顯示)海明威(1899~1961),美國現(xiàn)代作家,20世紀美國文學(xué)史上最耀眼的名字之一。早期作品表現(xiàn)了第一次世界大戰(zhàn)青年一代的彷徨情緒,以“迷惘的一代”的代表著稱。20世紀末回到美國,寫了不小以拳擊家、漁民、獵人等為主人公的短篇小說,創(chuàng)造了“硬漢子”性格。
(1)請同學(xué)們結(jié)合日常生活實例和教材分析說明人類要在世界各地消除貧困并保持人口的合理容量任務(wù)的艱巨性?(2)采取何種措施才能更好的解決這一問題的出現(xiàn)?教師總結(jié)(1)現(xiàn)實中的人口問題(如人口過快增長、人口城市化和人口老齡化等)引發(fā)了嚴重的資源問題和環(huán)境問題。①發(fā)達國家的人均消耗資源量很大,索取資源和轉(zhuǎn)嫁有害生產(chǎn)的地域超出了本國的范圍。②發(fā)展中國家不僅人口數(shù)量多,人均消費水平低,而且一些國家的人口仍在快速增長。若在現(xiàn)有的經(jīng)濟基礎(chǔ)上,把發(fā)展中國家人均生活質(zhì)量提高到與發(fā)達國家相當?shù)乃?,所引發(fā)的資源短缺和環(huán)境問題將會相當嚴重,解決的難度也很大。(2)I就整個世界來說:①國際社會要倡導(dǎo)各國,尤其發(fā)展中國家要盡最大可能把人口控制在合理的規(guī)模之內(nèi);②建立公平的秩序,保證大多數(shù)人擁有不斷追求高水平生活質(zhì)量的平等權(quán)利。
【明確】“一夫當關(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。
