四、品味詩歌藝術(shù)1、詩人是如何表現(xiàn)其品質(zhì)的?運(yùn)用了什么修辭手法?產(chǎn)生了怎樣的表達(dá)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(dòng)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(dá)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(yùn)用,在政治不清明的時(shí)代,借用“移情”,可言難言之語,抒難抒之情。請(qǐng)找出相關(guān)的詩句,說說詩人是怎樣運(yùn)用這些比喻來表達(dá)政治理想的。
【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(fēng)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(qiáng)烈鮮明的美丑、善惡對(duì)比;豐富生動(dòng)、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(duì)外國(guó)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(shí)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(yùn)的文字,對(duì)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(dú)立思考的學(xué)習(xí)慣,指點(diǎn)進(jìn)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(dá)到以學(xué)帶讀,以讀促學(xué)的目的。
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(shí)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(dòng)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(shí)中來。這句景物描寫點(diǎn)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(gè)音樂形象補(bǔ)足了畫龍點(diǎn)睛之筆。
【明確】“一夫當(dāng)關(guān),萬夫莫開”言劍閣有易守難攻的險(xiǎn)要形勢(shì),暗示中央朝廷的部隊(duì)很不容易打進(jìn)來,因而野心家可以據(jù)險(xiǎn)發(fā)動(dòng)叛亂,“化為狼與豺”,搞地方割據(jù)。如果割據(jù)勢(shì)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(shí):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(dòng)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(xiǎn)要引出對(duì)政治形勢(shì)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(shí)的社會(huì)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(duì)國(guó)事的憂慮與關(guān)切,為詩篇增加了現(xiàn)實(shí)的內(nèi)涵、深厚的意蘊(yùn)。唐天寶初年,太平景象背后正潛伏著危機(jī),后來發(fā)生的安史之亂,證明詩人的憂慮是有現(xiàn)實(shí)意義的。
六、到此為止,我們了解到,作者對(duì)“笑”鯤鵬和別人的蜩與學(xué)鳩、斥鴳、宋榮子都一一作了否定。那么請(qǐng)大家討論一下,1、作者對(duì)鯤鵬和“知效一官,行比一鄉(xiāng),德合一君,而征一國(guó)者”是不是肯定呢?明確:也都作了否定。否定后者好理解,關(guān)鍵是否定前者不好理解,因?yàn)椤蚌H鵬展翅”早已作為積極的意象被人們廣泛引用。但在本文中,作者在講述這一寓言故事時(shí),突出的不是鯤鵬本身,而是風(fēng)力,“故九萬里,風(fēng)斯在下矣,而后乃今培風(fēng);背負(fù)青天,而莫之夭閼者,而后乃今將圖南”。對(duì)風(fēng)力作用的突出,實(shí)際上就是對(duì)鯤鵬的否定。作者寫了“笑”的雙方,對(duì)“笑”的一方蜩與學(xué)鳩、斥鴳、宋榮子都作了否定,對(duì)被“笑”的一方鯤鵬和“知效一官,行比一鄉(xiāng),德合一君,而征一國(guó)者”也都作了否定,并且對(duì)順便提及的野馬、塵埃、芥、大舟、朝菌、蟪蛄、冥靈、大椿、彭祖、列子等事物或者人物也都作了否定。這種全盤否定的態(tài)度,如果我們借用本文中的一個(gè)形象的詞語,可以說是:笑!是的,本文也可以說是:莊子“笑”萬物!
教學(xué)目標(biāo):1、知識(shí)與能力:(1)識(shí)記:理性、啟蒙運(yùn)動(dòng);伏爾泰、孟德斯鳩、盧梭等偉大的啟蒙思想家及其主張;康德及啟蒙運(yùn)動(dòng)的影響;(2)理解啟蒙運(yùn)動(dòng)興起的背景,分析啟蒙思想的巨大影響;(3)認(rèn)識(shí)上層建筑對(duì)社會(huì)發(fā)展的巨大反作用。2、過程與方法:(1)指導(dǎo)學(xué)生用表格法掌握啟蒙運(yùn)動(dòng)主要代表人物及其思想主張;(2)運(yùn)用比較法加深對(duì)啟蒙思想家觀點(diǎn)共性和個(gè)性的認(rèn)識(shí)。(3)運(yùn)用比較法對(duì)比文藝復(fù)興和啟蒙運(yùn)動(dòng)的異同,說明啟蒙運(yùn)動(dòng)對(duì)人文主義思想的發(fā)展。3、情感態(tài)度與價(jià)值觀:(1)通過本課的學(xué)習(xí),讓學(xué)生認(rèn)識(shí)到“一定的文化是一定社會(huì)的政治和經(jīng)濟(jì)在觀念上和形態(tài)上的反映”;(2)學(xué)習(xí)啟蒙思想家追求真理的精神,培養(yǎng)學(xué)生遠(yuǎn)大的理想與抱負(fù);(3)通過法國(guó)啟蒙思想產(chǎn)生的巨大影響的分析,使學(xué)生認(rèn)識(shí)意識(shí)形態(tài)對(duì)社會(huì)發(fā)展所起的重大作用,從而提高學(xué)習(xí)理論的自覺性。

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. Thank you for your listening !5.Revise your writing each other.Does he/she explain how music has changed his/her/someone else’s life?Are some of the rhetorical devices included and used properly ?Does he/she talk about how music makes him/her/someone feel?Is the first word in each sentences capitalised?Does he/she use correct punctuation ?
1.國(guó)家石油價(jià)格上漲,導(dǎo)致依賴于國(guó)際石油而建立起來的日本重化工業(yè)的制造成本提高,產(chǎn)品價(jià)格相應(yīng)提高,削弱了日本重化工產(chǎn)品在國(guó)際市場(chǎng)上的競(jìng)爭(zhēng)力。2.日元 的大幅度升值,意味著日本產(chǎn)品在國(guó)際市場(chǎng)上的價(jià)格大幅度提高。例如,同樣的日本產(chǎn)品,如果原來在國(guó)際市場(chǎng)上賣1美元,日元升值1倍后其在國(guó)際市場(chǎng)上的售價(jià)就達(dá)2美元。所以,以國(guó)際市場(chǎng)為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉(zhuǎn)移。3.自身市場(chǎng)滿足不了發(fā)展需求,國(guó)際市場(chǎng)上亞洲發(fā)展中國(guó)家和地區(qū)的同類產(chǎn)品具有明顯的價(jià)格優(yōu)勢(shì)。所以,日本企業(yè)在其國(guó)內(nèi)發(fā)展的空間很小。4.勞動(dòng)力價(jià)格高反映為產(chǎn)品的價(jià)格高,而勞動(dòng)力數(shù)量又滿足 不了企業(yè)進(jìn)一步擴(kuò)展對(duì)勞動(dòng)力的需求。所以,日本從事傳統(tǒng)產(chǎn)業(yè)的國(guó)內(nèi)企業(yè)生產(chǎn)受勞動(dòng)力價(jià)格和數(shù)量的雙重制約。5.促進(jìn)日本企業(yè)生產(chǎn)的區(qū)位選擇向國(guó)土的南、北部和海外擴(kuò)展。6.“技術(shù)立國(guó)”的政策明顯對(duì)傳統(tǒng)產(chǎn)業(yè)在國(guó)內(nèi)生產(chǎn)不利,即企業(yè)生產(chǎn)要么向知識(shí)技術(shù)密集型轉(zhuǎn)換(這需要大量的投資),要么轉(zhuǎn)向海外。
