    人教版高中語文必修5《宇宙的未來》教案

    (2)怎樣理解本文的一些相關(guān)論述?【明確】這是一篇科學(xué)講演,涉及較為復(fù)雜的背景知識。這些知識和講演的主題是密切相關(guān)的,如果不作必要的交待,講演的內(nèi)容就會顯得抽象和單薄。如,談到天氣預(yù)報、大腦工作原理都具有混沌性質(zhì),來反襯宇宙在大尺度上是"平滑而非混沌"的;如,談到恒星的死亡(歸宿)引出黑洞,為宇宙中暗物質(zhì)的存在尋找理論支持;如,談到現(xiàn)存宇宙對初始密度的極度敏感,引出了"人擇原理"等等。這些相關(guān)的論述,或從對立面凸顯觀點(diǎn),或從縱深面強(qiáng)化觀點(diǎn),使論證豐富多彩。(3)這篇講演在語言上具有怎樣的特點(diǎn)?【明確】講演是面對面的交流,這種交流又是單向度的,如果不注意講演的語言藝術(shù),就達(dá)不到最佳的表達(dá)效果。這篇講演,除了推理嚴(yán)謹(jǐn)外,語言幽默也是其突出的特點(diǎn)。幽默的語言創(chuàng)造出一種輕松愉快的氣氛,更具有親和力,使所闡發(fā)的事理更容易為聽眾接受。

    六、到此為止,我們了解到,作者對“笑”鯤鵬和別人的蜩與學(xué)鳩、斥鴳、宋榮子都一一作了否定。那么請大家討論一下,1、作者對鯤鵬和“知效一官,行比一鄉(xiāng),德合一君,而征一國者”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,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”。對風(fēng)力作用的突出,實(shí)際上就是對鯤鵬的否定。作者寫了“笑”的雙方,對“笑”的一方蜩與學(xué)鳩、斥鴳、宋榮子都作了否定,對被“笑”的一方鯤鵬和“知效一官,行比一鄉(xiāng),德合一君,而征一國者”也都作了否定,并且對順便提及的野馬、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形象的詞語,可以說是:笑!是的,本文也可以說是:莊子“笑”萬物!

    人教版高中語文必修5《咬文嚼字》教案

    【教學(xué)過程】第一課時一、導(dǎo)入新課清代唐彪在《讀書作文譜》中引用武叔卿的話說:“文章有一筆寫成不加點(diǎn)綴而工者,此神到之文,尚矣。其次須精思細(xì)改,如文章草創(chuàng)已定,便從頭至尾—一標(biāo)點(diǎn)?!蓖瑢W(xué)們能列舉出文學(xué)史上的作家哪些屬于前者,哪些屬于后者嗎?前者有李白。后者如賈島、王安石、歐陽修、曹雪芹等。(賈島有關(guān)于推敲的典故。王安石修改“春風(fēng)又綠江南岸”句傳為佳話。歐陽修《醉翁亭記》的開頭便是精心改成的。《紅樓夢》更是“披閱十載,增刪五次?!保┨釂枺汗沤竦膫ゴ笞骷覟槭裁聪窭畎资降脑娙撕苌?,而大多數(shù)人卻都要“咬文嚼字”,苦苦修改呢?這節(jié)課我們就來研究一下這個問題。二、整體感知1.快速瀏覽全文,熟悉主要內(nèi)容。2.根據(jù)“學(xué)習(xí)重點(diǎn)”,確立學(xué)習(xí)目標(biāo)。三、課文分析1.理清觀點(diǎn)與材料的關(guān)系。首先,讓學(xué)生找出本文在論證中所運(yùn)用的材料。

    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(dá)出自己對于丈夫深深的思戀之情,描寫了閨中生活的孤獨(dú)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(shí),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(dú)、愁悶的生活狀態(tài)和內(nèi)心情感。

    (一)上片:描寫杭州的自然風(fēng)光和都市的繁華“東南形勝,三吳都會,錢塘自古繁華”,“東南形勝”,是從地理條件、自然條件著筆寫的。杭州地處東南,地理位置很重要,風(fēng)景很優(yōu)美,故曰:“形勝”?!叭齾嵌紩?,是從社會條件著筆寫的。它是三吳地區(qū)的重要都市,那里人眾薈萃,財貨聚集,故曰:“都會”?!板X塘自古繁華”,這一句是對前兩句的總結(jié),因?yàn)楹贾菥哂羞@些特殊條件,所以“自古繁華”。下面就對“形勝”、“都會”和“自古繁華”進(jìn)行鋪敘。“煙柳畫橋,風(fēng)簾翠幕,參差十萬人家”是對“三吳都會”的展開描寫?!霸茦淅@堤沙。怒濤卷霜雪,天塹無涯”是對“東南形勝”的展開描寫。這里選擇了錢塘江岸和江潮兩種景物來寫。“市列珠璣,戶盈羅綺,競豪奢”是對“錢塘自古繁華”的展開描寫。描寫了兩個方面:一是商業(yè)貿(mào)易情況——“市列珠璣”,只用市場上的珍寶,代表了商業(yè)的豐富、商業(yè)的繁榮;二是衣著情況——“戶盈羅綺”,家家披羅著錦。“競豪奢”,又總括杭州的種種繁華景象。

    人教版高中地理必修3森林的開發(fā)和保護(hù)教案

    角色扮演:學(xué)生扮演政府官員、熱帶叢林土著居民、 世界環(huán)保組織官員、開發(fā)商等角色,從角色的立場討論亞馬孫河流域熱帶雨林的開發(fā)活動規(guī)則: 每個小組認(rèn)領(lǐng)一種角色,用5分鐘的時間討論和整理思路,然后推薦一位代表做中心發(fā)言,小組的其他同學(xué)可以隨時補(bǔ)充。發(fā)言時請說 明所扮演的角色,盡可能多的發(fā)表建設(shè)性意見。如果需要,可以上臺展示材料【學(xué)生互動】 風(fēng)云辯論:雨林破壞誰之錯?正方觀點(diǎn):雨林破壞,亞馬孫地區(qū) 的國家和 居民應(yīng)負(fù)主要責(zé)任反方觀點(diǎn): 雨林破壞,發(fā)達(dá)國家應(yīng)負(fù)主要責(zé)任 【師生小結(jié)】 雨林的開發(fā),既有發(fā)展中國家經(jīng)濟(jì)的需要,也有發(fā)達(dá)國家國際市場的牽動。保護(hù)雨林,是全人類的共同責(zé)任,尤其發(fā)達(dá)國家應(yīng)該承擔(dān)更多的責(zé)任。保護(hù)亞馬遜雨林符合長遠(yuǎn)利益和全球利益。但這與雨林所在地國家的發(fā)展產(chǎn)生了矛盾,如何解決之一矛盾是雨林開發(fā)與保護(hù)的關(guān)鍵。【過渡承轉(zhuǎn)】 綠色和平組織警告說,如果不采取有效措施制止對森林的破壞,80年內(nèi)熱帶雨林可能完全從地球上消失。開發(fā)還是保護(hù)?這是雨林的兩種前途,也

    人教版新課標(biāo)高中物理必修2功率教案2篇

    1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運(yùn)動,則力對物體做功的功率保持不變。此情況下,任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機(jī)器通常有一個額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當(dāng)路面阻力較小時,牽引力也小,速度大,即汽車可以跑得快些;當(dāng)路面阻力較大,或爬坡時,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機(jī)器在實(shí)際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時增大,但是這一情況應(yīng)以二者乘積等于額定功率為限度,即當(dāng)實(shí)際功率大于額定功率以后,這種情況不可能實(shí)現(xiàn)。
