知識與技能1.了解大牧場放牧業(yè)和乳畜業(yè)兩種農(nóng)業(yè)地域類型及其分布。2.通過學習大牧場放牧業(yè),學會分析農(nóng)業(yè)區(qū)位因素,訓練讀圖分析能力。3.掌握大牧場放牧業(yè)在經(jīng)營方式、商品化、專業(yè)化、經(jīng)濟效益等方面的特點。4.解西歐乳畜業(yè)的形成因素。過程 與方法1.通過對潘帕斯草原大牧場放牧業(yè)區(qū)位因素的分析,學會歸納大牧場放牧業(yè)的區(qū)位條件。2.把西歐乳畜業(yè)和潘帕斯草原大牧場放牧業(yè)的區(qū)位條件作比較。情感態(tài)度與價值觀1.自然條件是農(nóng)業(yè)地域類型形成的條件,人類必須尊重自然規(guī)律,才能天人合一。2.人文條件也越來越大地影響到農(nóng)業(yè)的區(qū)位選擇,事物是發(fā)展的,不能用靜止的觀點看待問題。【教學重點】1.理解大牧場放牧業(yè)和乳畜業(yè)兩類農(nóng)業(yè)地域類型的區(qū)位因素。2.利用圖表資料分析農(nóng)業(yè)區(qū)位因素的能力。
1.本文由“不得極夫游之樂”生發(fā)出“盡吾志”的觀點,又由“仆碑”生發(fā)出“深思慎取”的觀點,這兩個觀點彼此有聯(lián)系嗎?作者游褒禪山,本來是一次平常的游歷活動,但卻從中悟出了人生哲理──從前洞后洞游人的多少悟出“夷以近,則游者眾;險以遠,則至者少”,從“入之愈深,其進愈難,而其見愈奇”悟出“而世之奇?zhèn)ァ⒐骞?、非常之觀,常在于險遠”;由此再引申一步,就得出了“非有志者不能至”的結(jié)論。然后將這次游山而未能“極夫游之樂”的教訓升華到理論上來,具體分析了“至”的幾個條件,最后得出“盡吾志”的觀點──這正是“求思之深而無不在”的結(jié)果。由此可見,“盡吾志”的觀點跟“深思慎取”的觀點是有聯(lián)系的:“盡吾志”的觀點是在“深思慎取”的基礎(chǔ)上產(chǎn)生的;有了這個觀點,又能反過來促使人們“深思慎取”,二者是相輔相成的。
從《詩經(jīng)》的現(xiàn)實主義到屈原的浪漫主義,是中國詩歌發(fā)展的一個里程碑。屈原的騷體詩,依詩取興,引類譬喻,繼承發(fā)展了《詩經(jīng)》的比興傳統(tǒng)?!对娊?jīng)》的比興較為單純,而《楚辭》的比興具有象征的特質(zhì),往往成為一個形象的系統(tǒng)?!峨x騷》中香草美人的比興就是范例。楚地本是澤鄉(xiāng)山國,其間頗有疊波曠宇、崇山秀嶺,這些江山的光怪之氣足以搖蕩心靈、催發(fā)麗辭偉句。但騷體詩已沖破《詩經(jīng)》四言詩的固定格式,句式加長而靈活,篇章放大而嚴密,詩采絢麗而貼切,是《詩經(jīng)》之后的一次詩體大解放。有人說,中國歷代詩“莫不同祖風騷”,足見其對后代詩歌的影響。先秦時代,《詩經(jīng)》與《楚辭》雙峰并峙,是中國詩史上現(xiàn)實主義與浪漫主義的兩座巍然屹立的坐標。
讀《環(huán)境污染組圖》思考:造成交通擁擠的原因是什么?有什么危害?(原因:汽車的增加、汽車數(shù)量與道路狀況的比值越來越大造成的。危害:交通阻塞,導致時間和能源的嚴重浪費,影響城市環(huán)境質(zhì)量。)3.增加就業(yè)困難,失業(yè)人數(shù)增多思考:產(chǎn)生這個問題的原因是什么?(隨著城市化發(fā)展,城市科學技術(shù)提高,機器化大生產(chǎn)使勞動者數(shù)量要求降低,城市人口本來就未充分就業(yè),再加上鄉(xiāng)村人口大量涌入,導致失業(yè)人數(shù)增多。)二、解決辦法:(以上海市為例,講解解決的辦法。)1.改善城市環(huán)境:治理河流、控制大氣污染物、大力加強綠化建設為改善城市環(huán)境,上海市全面展開對大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強綠化建設,截止1990年,市區(qū)綠化覆蓋率達到20.3%。
(幻燈六)巴金作品《家》描寫的是“五四”之后,成都地區(qū)一個封建大家庭走向崩潰的故事。故事集中在1920年冬到1921年秋的八九個月時間里。成都的一個官僚地主家庭高公館,一家之主的高老太爺,封建專制,頑固不化。長房長孫覺新,為人厚道,卻很軟弱,原與梅表姐相愛,后屈從于老太爺之命而與李瑞玨結(jié)婚。后來梅和瑞玨雙雙慘死。覺新的胞弟覺民、覺慧積極參加愛國運動,從而和馮公館的馮樂山成了死對頭。覺民愛上琴,馮樂山卻要他娶自己的侄孫女,在覺民覺慧的反抗下,他們終于取得勝利。覺慧愛上聰明伶俐的婢女鳴鳳,但馮樂山卻指名要娶鳴鳳為妾,鳴鳳堅決不從,投湖自盡…至此,覺新有所覺醒,而覺慧則毅然脫離家庭,投身革命。(故事主要以高家三兄弟的愛情遭際為線索。)
2、黛玉進入賈府到賈母處,她看到了什么?提示:從榮府西角門進去,走“一射之地”,轉(zhuǎn)至垂花門,過穿堂,繞插屏,再經(jīng)三間過廳,后面方是賈母居住的正房大院?!罢嫖彘g上房,皆雕梁畫棟,兩邊穿山游廊廂房,掛著各色鸚鵡、畫眉等鳥雀。”這樣穿堂過廳一路行來,仆役、婆子、丫環(huán)輪番更換,的確給人以侯門深似海的感覺。然而賈母居處還不是正內(nèi)室。3、黛玉去拜見二舅舅時又看到什么?提示:往東?!按┻^一個東西的穿堂,向南大廳之后,儀門內(nèi)大院落,上面五間大正房,兩邊廂房鹿頂耳房鉆山,四通八達,軒昂壯麗”。堂屋中迎面“一個赤金九龍青地大匾,匾上寫著斗大的三個大字,是‘榮禧堂’,后有一行小字:‘某年月日,書賜榮國公賈源’,又有‘萬幾宸翰之寶’?!蔽輧?nèi)擺設有名貴的家具,珍貴的字畫、古玩?!坝钟幸桓睂β?lián),乃烏木聯(lián)牌,鑲著鏨銀的字跡,道是:座上珠譏昭日月,堂前黼黻煥煙霞?!庇商梦葸M入東耳房,這里是起居室,另有一番布置,再到東廊三間小正房王夫人的住室,又別有擺設。
【參考】“滄海月明珠有淚,藍田日暖玉生煙?!睖婧V械恼渲橹挥性诿髟轮?,才能流下晶瑩的淚花;藍田下的美玉只有在日暖之時,才能升騰飄逸的煙霞。物猶如此,人當如是。“滄海月明”與“藍田日暖”優(yōu)美意境的創(chuàng)設,不僅僅是詩人精妙絕倫藝術(shù)素養(yǎng)的表現(xiàn)和揮灑,更是詩人回答人生價值的標準和尺度。詩人以物推人,拓展深化了詩作的主題,整篇的閃光點在此,魂亦在此。【參考】“此情可待成追憶,只是當時已惘然?!弊窇涍^去,盡管自己以一顆浸滿血淚的真誠之心,付出巨大的努力,去追求美好的人生理想,可“五十弦”如玉的歲月、如珠的年華,值得珍惜之時卻等閑而過;面對現(xiàn)實:戀人生離、愛妻死別、盛年已逝、抱負難展、功業(yè)未建……,幡醒悟之日已風光不再。如泣如訴的悲劇式結(jié)問,又讓詩人重新回到對“人生價值到底是什么?到底該怎樣實現(xiàn)?”深深的思考和迷惑之中,大大增強了詩作的震撼力。

(四)反思總結(jié),當堂檢測。本節(jié)內(nèi)容講述了價格變動對人們生活、生產(chǎn)的影響作用,主要知識框架如下:(1)、價格變動會影響人們的消費需求,商品價格上漲,人需求就減少,反之,則增大。價格變動對不同商品需求影響程度是不一樣的,對生活必需品的需求量影響較小,對高檔耐用品的需求量影響較大。相關(guān)商品價格變動對消費需求的影響不同,某種商品價格上漲,就會減少需求量,其替代品需求量增加,其互補品需求量則減少。(2)、價格變化也會影響生產(chǎn)經(jīng)營,價格變動會調(diào)節(jié)生產(chǎn),刺激生產(chǎn)者改進技術(shù),提高勞動生產(chǎn)率,促使生產(chǎn)者生產(chǎn)適銷對路的高 質(zhì)量產(chǎn)品。(五)發(fā)導學案、布置預習。預習第三課第一框《消費及其類型》,完成預習導學案練習題九、板書設計《價格變動的影響》1、對人們生活的影響(1)商品價格變動與消費需求量之間的關(guān)系(2)不同商品的需求量對價格變動的反應程度不同

一、描述圓周運動的物理量 探究交流 打籃球的同學可能玩過轉(zhuǎn)籃球,讓籃球在指尖旋轉(zhuǎn),展示自己的球技,如圖5-4-1所示.若籃球正繞指尖所在的豎直軸旋轉(zhuǎn),那么籃球上不同高度的各點的角速度相同嗎?線速度相同嗎? 【提示】 籃球上各點的角速度是相同的.但由于不同高度的各點轉(zhuǎn)動時的圓心、半徑不同,由v=ωr可知不同高度的各點的線速度不同.
(三)作家介紹,寫作背景大家說“雨巷”這首詩寫得美不美?(美)剛才我也說了,這首詩是中國朦朧詩的百年經(jīng)典。那么對于這么出名的詩,有誰能夠向我們介紹一下它的作者跟寫作背景呢?(明確:戴望舒,原名戴朝實又名戴夢鷗,1905年出生于杭州。1929年4月出版第一本詩集《我底記憶》,他的成名作《雨巷》即收入此集中。1933年8月出版了《望舒草》1948年出版了《災難歲月》一生留下了詩篇92首。《雨巷》是戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩人”的雅號。這首詩寫于1927年夏天。當時全國處于白色恐怖之匯總,戴望舒因曾參加進步活動而不得不避居于松江的友人家中,在孤寂中咀嚼著大革命失敗后的幻滅與痛苦,心匯總充滿了迷惘的情緒和朦朧的希望。)(適當板書)
教師在教學古詩時,只有指導學生反復朗讀,才能讓學生直接體會到古詩所具有的音樂美,增強學生對古詩的美學感染力,進一步激發(fā)學生學習古詩詞的熱情。除此,在《荷塘月色》、《春》等優(yōu)美的寫景抒情散文中,朱自清運用了不少的疊詞,朗讀它們,猶如一個個跳動的音符貫穿于文章中,有效地增強了文章的節(jié)奏感。通過朗讀,學生能夠更好地領(lǐng)悟到朱自清散文所具有的音樂美。4、朗讀能夠增強學生對文章含蓄美和形象美的感染能力:含蓄,是指用少量的、具體的、可感觸的藝術(shù)形象,來表現(xiàn)豐富的生活內(nèi)容和思想感情,把詩意藏在富于概括性和內(nèi)涵豐富的形象中,以瞬間表現(xiàn)永恒,以有限傳達無限,以少勝多,給人以推理和想象的廣闊大地?!白x書百遍,其義自見”,“熟讀唐詩三百首,不會作詩也會吟”,“觀書須熟讀,使其言皆者出于吾云之口;繼以精思,使其意皆出于吾之心。”這些話語道出了反復朗讀對于理解文章含義所起的重要作用。教師在課堂教學過程中,特別是地教學詩歌時,只有指導學生反復地朗讀,才能讓學生將文章中雋永的意境,深厚的蘊涵更好地品味出來,從而更好地欣賞到文章的含蓄美。
一、內(nèi)容與解析內(nèi)容:科普說明文《動物游戲之謎》。解析:《動物游戲之謎》是高中語文(必修)3第四單元的一篇科普說明文??茖W是人類認識世界的重要工具,是人類文化的重要組成部分,是標志人類文明的尺度。閱讀科普文章,可以啟迪心志,激發(fā)想象,帶領(lǐng)我們進入全新的科學天地,在科學海洋中遨游。本文思路清晰,內(nèi)容生動,揭開了動物日常游戲行為的神秘面紗,擺出研究者的種種結(jié)論,既讓我們擴大了視野,增長了知識,也讓我們明白了科學探索永無止境。學習本文的重點是提高的科普文的閱讀能力,培養(yǎng)學生勤于探索、勇于鉆研的科學精神。二、教學目標及解析1、理清文章思路,明確本文的說明內(nèi)容和順序。2、品讀文章,感受本文的語言特色。3、激發(fā)探究興趣,培養(yǎng)篩選信息、提取要素及概括敘述的能力。4、挖掘人文內(nèi)涵,培養(yǎng)學生保護動物的意識和勤于探索、勇于鉆研的科學精神。

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 motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. 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. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
