1. 完成文本主要信息填空(斜體字部分設(shè)空):As a witness to farmers’ poor harvests and even a severe shortage of food, Yuan Longping was determined to devote his life to tackling this crisis. After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continues to turn one vision after another into realities.2. 模仿寫作:Do some research via the Internet and introduce another agricultural scientist, Chen Risheng(陳日勝), using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【設(shè)計意圖】任務1是對文本內(nèi)容和詞匯學習成效的檢測。任務2借助文本中學到的詞匯和寫作手法仿寫另一位科學家,提升學生遷移運用詞匯、文體結(jié)構(gòu)和寫作方法的能力。

本單元閱讀文本向中學生推薦職業(yè)能力測試(Career Aptitude Test),旨在建議學生利用職業(yè)傾向測試來發(fā)現(xiàn)自己更感興趣、更有潛力的學習或職業(yè)方向,并規(guī)劃自己的未來職業(yè)。 本文采用了建議性文本,全篇從職業(yè)生涯的重要意義講起,針對中學生對職業(yè)規(guī)劃比較迷茫的現(xiàn)狀,提出了職業(yè)傾向測試這一建議。全文共七段,其中第一段和第二段為第一部分,其余五段為第二部分。第一部分論述職業(yè)的重要性和職業(yè)生涯規(guī)劃的最佳時間是在校期間,第二部分提出解決職業(yè)選擇困惑可以通過完成職業(yè)能力測試,介紹了不同種類的職業(yè)傾向測試,結(jié)合圖表詳細說明其中一種操作步驟,并提醒職業(yè)建議也基于學歷和經(jīng)驗,最后一段概括論述,建議學生通過職業(yè)能力測試這一有效的工具,找到自己真正熱愛的事物。 在文本教學設(shè)計時,要幫助學生梳理有關(guān)職業(yè)的話題語言。閱讀策略層面,指導學生通過學習圖表和圖形,在有限的空間內(nèi)獲取廣泛信息,如閱讀圖表標題,圖表上的標簽,X軸Y軸上的數(shù)據(jù)所指。
【引入新課】同學們在河邊玩耍的時候不知注意到如圖中所展示的場面沒有?(注意到了)那么同學們知道圖中A、B、C它們的名稱分別是什么嗎?(不知道)它們的名稱簡單的講可以統(tǒng)稱為河流地貌。至于它們的具體名稱和形成原理就是我們今天要討論的問題。一、河流地貌【介紹】河流地貌是自然界中最常見的地貌之一。按照成因,可以將河流地貌分為侵蝕地貌和堆積地貌,它們的形成和發(fā)展主要與外力作用有關(guān)?!景鍟?、分類: 侵蝕地貌和堆積地貌【過渡】我們首先來看一下河流侵蝕地貌【板書】2、河流侵蝕地貌【介紹】河流在流動過程 中,會破壞并掀起地表的物質(zhì),形成侵 蝕地貌。河流侵蝕地貌是由溯源侵蝕、下蝕和側(cè)蝕共同作用形成的?!疽龑ёx書】請同學們快速閱讀教材P83倒數(shù) 第二段,添出以下表格。
師:很好。由于存在地球大氣圈、地球水圈和地表的礦物,在地球上這個合適的溫度條件下,形成了適合于生物生存的自然環(huán)境。人們通常所說的生物,是指有生命的物體,包括植物、動物和微生物。據(jù)估計,現(xiàn)有生存的植物約有40萬種,動物約有110多萬種,微生物至少有10多萬種。據(jù)統(tǒng)計,在地質(zhì)歷史上曾生存過的生物約有5億~10億種之多,然而,在地球漫長的演化過程中,絕大部分都已經(jīng)滅絕了?,F(xiàn)存的生物生活在巖石圈的上層部分、大氣圈的下層部分和水圈的全部,構(gòu)成了地球上一個獨特的圈層,稱為生物圈。生物圈是太陽系所有行星中僅在地球上存在的一個獨特圈層。課堂小結(jié):地球所有的外部圈層是相互滲透、相互影響,甚至相互重疊的,在太陽和人類生活的參與下,整個地球生機盎然;同時,它們起著保護地球的作用,可以減弱太陽和宇宙輻射對地表的影響,減少宇宙中的隕石對地球表面的撞擊。外部各圈中的物質(zhì)運動和循環(huán),是促使地表物質(zhì)和形態(tài)演變的重要動力。
三維目標:知識和技能 1、了解地球自轉(zhuǎn)和公轉(zhuǎn)的方向及一些基本數(shù)據(jù):周期、速度、公轉(zhuǎn)軌道、黃赤交角。2、理解由于地球自轉(zhuǎn)運動造成的晝夜交替、地方時差,掌握時間的有關(guān)換算,能正確判斷晨昏線。3、理解地球自轉(zhuǎn)和公轉(zhuǎn)的關(guān)系,理解太陽直射點的南北移動的過程及其原因,并能演示其運動規(guī)律。4、理 解晝夜長短和正午太陽高度的季節(jié)變壞緯度變化 。過程與方法 1、通過運用地球儀演示地球的自傳和公轉(zhuǎn)現(xiàn)象,學生能夠準確的畫出夏至日到冬至日太陽照射地球的示意圖2、能根據(jù)“二分二至日太陽照射地球示意圖”分析全球各 地的晝夜長短和正午太陽高度的變化,分析同緯度地區(qū)不同季節(jié)和不同緯度地區(qū)相同季節(jié)的晝夜長短和正午太陽高度的變化。
當時,不只發(fā)生了太陽風暴,同時還有其它的現(xiàn)象發(fā)生,導致災難巨大。 如果,這些現(xiàn)象單獨地發(fā)生,結(jié)果就會是另外一個樣子。正是由于這些因素綜合起來,1859年的太陽風暴,才在人類歷史上留下了濃墨重彩的一筆。太陽磁暴開始干擾通信日本衛(wèi)星首個被“擊中”日本航天機構(gòu)29日聲明,受強烈的太陽磁暴影響,28日晚,日本“兒玉(Kodama)”通訊衛(wèi)星信號中斷。 據(jù)美聯(lián)社報道,在太陽黑子活動減弱后,“兒玉”通訊衛(wèi)星恢復正常運轉(zhuǎn)。 美歐研究人員28日發(fā)布新聞公告稱,太陽當天發(fā)生了一次強烈的耀斑爆發(fā),預示著新一輪太陽風暴將在今后一兩天內(nèi)抵達地球,地球上的通信等設(shè)施可能會因此受到部分干擾。與這次耀斑爆發(fā)相伴,太陽表面還產(chǎn)生了一股強大的日冕物質(zhì)噴射,方向幾乎直沖地球。研究人員說,噴射產(chǎn)生的帶電粒子流正以約每小時750萬公里的速度奔地球而來,其與地球磁場作用后可能會形成比較強烈的地磁暴,使地球兩極出現(xiàn)極光,并可能對衛(wèi)星運行和通信等造成干擾。
過渡:在實際生活中,城市內(nèi)部空間結(jié)構(gòu)并非完全按照這一經(jīng)濟規(guī)律呈現(xiàn),而是更具復雜性。這說明除了經(jīng)濟因素外,還有很多其他因素在起作用,請大家結(jié)合你的認識、圖2.9和案例1:紐約市的少數(shù)民族區(qū)談談你的看法。(2)其他因素I收入——形成不同級別住宅區(qū)的常見原因。有能力支付昂貴租金和選擇最佳居住環(huán)境的人,其居住地往往形成高級住宅區(qū)。II知名度——城市內(nèi)某些地區(qū)在歷史、文化或經(jīng)濟方面具有很高的聲譽,這往往會吸引更多新的住宅或商場建在該處,以提高其知名度。III種族聚居區(qū)的形成——在有些城市的某一區(qū)域內(nèi),如果某個種族或宗教團體占優(yōu)勢,就可能形成種族聚居區(qū)。如紐約市的唐人街、哈林區(qū)、小意大利區(qū)等。IV歷史因素——城市的建筑物和街道設(shè)計可以維持久遠,早期的土地利用方式對日后的功能分區(qū)有著深遠的影響。
1.國家石油價格上漲,導致依賴于國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)品價格相應提高,削弱了日本重化工產(chǎn)品在國際市場上的競爭力。2.日元 的大幅度升值,意味著日本產(chǎn)品在國際市場上的價格大幅度提高。例如,同樣的日本產(chǎn)品,如果原來在國際市場上賣1美元,日元升值1倍后其在國際市場上的售價就達2美元。所以,以國際市場為依托的日本傳統(tǒng)產(chǎn)業(yè)只好紛紛向海外轉(zhuǎn)移。3.自身市場滿足不了發(fā)展需求,國際市場上亞洲發(fā)展中國家和地區(qū)的同類產(chǎn)品具有明顯的價格優(yōu)勢。所以,日本企業(yè)在其國內(nèi)發(fā)展的空間很小。4.勞動力價格高反映為產(chǎn)品的價格高,而勞動力數(shù)量又滿足 不了企業(yè)進一步擴展對勞動力的需求。所以,日本從事傳統(tǒng)產(chǎn)業(yè)的國內(nèi)企業(yè)生產(chǎn)受勞動力價格和數(shù)量的雙重制約。5.促進日本企業(yè)生產(chǎn)的區(qū)位選擇向國土的南、北部和海外擴展。6.“技術(shù)立國”的政策明顯對傳統(tǒng)產(chǎn)業(yè)在國內(nèi)生產(chǎn)不利,即企業(yè)生產(chǎn)要么向知識技術(shù)密集型轉(zhuǎn)換(這需要大量的投資),要么轉(zhuǎn)向海外。
