人教版高中地理必修1全球氣候變化教案
科學(xué)家預(yù)測，就地區(qū)而言，位于低緯度的大部分國家，農(nóng)作物的產(chǎn)量將減少；而位于高緯度的國家，農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū)，因此，氣候變化的這種區(qū)域差異性，可能會使發(fā)展中國家所面臨的問題更為嚴(yán)峻。板書：3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹：全球變暖會影響整個水循環(huán)過程，可能使蒸發(fā)加大，改變區(qū)域降水量和降水分布格局，增加降水極端異常事件的發(fā)生，導(dǎo)致洪澇、干旱災(zāi)害的頻次和強度增加，以及地表徑流發(fā)生變化。隨著徑流減少，蒸發(fā)增強，全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折：既然全球變暖會引起很多不利影響，那么作為人類應(yīng)如何面對這一挑戰(zhàn)呢？這就是我們要討論的第三個問題。板書：三、氣候變化的適應(yīng)對策討論：請大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對策部分討論人類應(yīng)如何面對全球變暖這一問題 呢？
人教版高中地理必修3產(chǎn)業(yè)轉(zhuǎn)移教案
1．國家石油價格上漲，導(dǎo)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(yīng)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。

人教版高中語文必修1《鴻門宴》教案
劉邦：先看劉邦對項伯的表白（此話也是有意讓項伯轉(zhuǎn)述給項羽聽的）：“秋毫不敢有所近”——說“不敢”而不說“不曾”，多么恭順！“籍吏民，封府庫，而待將軍”——“待”，多么虔誠！“日夜望將軍至”——說“望”而不說“等”，多么迫切！再看劉邦的卑詞“謝罪”：他言必稱“將軍”，說自己與項羽“戮力而攻秦”，是戰(zhàn)友而非敵人；將“先入關(guān)破秦”說成是不自意，以表自己的力量不如項羽；把“得復(fù)見將軍于此”當(dāng)作是自己莫大的榮幸以滿足項羽的虛榮心；最后，他還把項羽的憤怒歸咎于“小人”的挑撥，為項羽推卸責(zé)任，及時給項羽一個臺階下。小結(jié)：項羽：沽名釣譽、輕敵自大、寡謀輕信、不善用人、剛愎自用、優(yōu)柔寡斷的一介武夫。劉邦：狡詐多謀、遇事果斷、臨危不懼、能屈能伸、善于用人。

1．根據(jù)下面的圖文資料，說明前蘇聯(lián)墾荒區(qū)土壤風(fēng)蝕的潛在自然背景。并說明人們的生產(chǎn)活動怎樣加劇了這個過程。點撥：對圖2.16的分析,要知道”墾荒地區(qū)”處于亞歐大 陸的中部偏北的地方,雖處于西風(fēng)帶但遠離水汽來源,故降水稀少。從其周邊的內(nèi)陸湖“里海”、“咸?！钡姆植继攸c，可以推斷，這是一個半荒漠向干草原的過渡地帶，是一個生態(tài)環(huán)境比較脆弱的地區(qū)，其自然地理狀況必定是寒冷、干旱、大風(fēng)。2．20世紀(jì)60年代中期以來，前蘇聯(lián)在總結(jié)大規(guī)模墾荒經(jīng)驗教訓(xùn)的基礎(chǔ)上，采取了一系列綜合防護措施。仔細分析這些措施，你認(rèn)為該地區(qū)防治荒漠化(土壤風(fēng)蝕)的主要方向是什么?點撥：要善于將所列四項保護措施逐條進行分析，而后進行歸納，不難找出它們之間的共同的東西，那就是“抗旱、防風(fēng)、保水、保土、保肥”。3．根據(jù)所學(xué)知識，你認(rèn)為前蘇聯(lián)墾荒區(qū)防治荒漠化的對策與措施可以被我國的哪些地區(qū)所借鑒。

知識與技能1．知道地心說和日心說的基本內(nèi)容．2．知道所有行星繞太陽運動的軌道都是橢圓，太陽處在橢圓的一個焦點上．3．知道所有行星的軌道的半長軸的三次方跟它的公轉(zhuǎn)周期的二次方的比值都相等，且這個比值與行星的質(zhì)量無關(guān)，但與太陽的質(zhì)量有關(guān)．4．理解人們對行星運動的認(rèn)識過程是漫長復(fù)雜的，真理是來之不易的．過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學(xué)家對行星運動的不同認(rèn)識，了解人類認(rèn)識事物本質(zhì)的曲折性并加深對行星運動的理解．情感、態(tài)度與價值觀1．澄清對天體運動裨秘、模糊的認(rèn)識，掌握人類認(rèn)識自然規(guī)律的科學(xué)方法．2．感悟科學(xué)是人類進步不竭的動力．教學(xué)重點理解和掌握開普勒行星運動定律，認(rèn)識行星的運動．學(xué)好本節(jié)有利于對宇宙中行星的運動規(guī)律的認(rèn)識，掌握人類認(rèn)識自然規(guī)律的科學(xué)方法，并有利于對人造衛(wèi)星的學(xué)習(xí)．
