人教版高中地理必修1第五章第二節(jié)自然地理環(huán)境的差異性教案
【補充說明】我們這節(jié)課簡要地分析了陸地環(huán)境的三種地域分異規(guī)律。實際上，世界上的任何事物有其一般性，也有它的特 殊性。在地帶性分異規(guī)律的基礎上，陸地環(huán)境因為受到海陸分布、地形 起伏等因素的影響，也會出現(xiàn)一些不規(guī)律的現(xiàn)象，這種現(xiàn)象稱為非地帶性。例如，我們在初中地理中學過綠洲。還記得什么叫綠洲嗎？再比如，在南美洲的西海岸（太平洋沿岸），有一條狹長的（熱帶）荒漠帶，而缺少熱帶草原帶，熱帶雨林帶主要是分布在赤道以北地區(qū)。這主要是受大的地形起伏的影響。因為南美洲西部是一列高大的安第斯山脈，受其影響，兩邊的氣候狀況不同，所以就出現(xiàn)了分布規(guī)律不同的自然帶，這也是一種非地帶性現(xiàn)象?！究偨Y】有規(guī)律分布的自然帶構成了全球和諧的自然環(huán)境整體。自然帶之間錯綜復雜的、微妙的要素關系，有許多是人類還沒有認識到的。因此，人類不能隨意去破壞任何哪怕是極微小的環(huán)節(jié)，也許它 帶來的影響會是全球性的。保護全球環(huán)境，人人有責。
人教版高中地理必修1第四章第三節(jié)河流地貌的發(fā)育教案
1．流水堆積地貌由于河床坡度降低，導致流速減小 ，或者其他原因，引起河流搬運能力降低，促使沉積發(fā)生，形成堆積地貌。常見的河流堆積地貌主要有以下幾種：(1)沖積扇平原沖積扇是河流出山口處的扇形堆積體。河流出 山口后，比降顯著減小，水流又分成許多交漢，成扇狀向外流動，河流能量顯著降低，大量物質堆積下來，又有利于河流改道。隨著各支汊的不斷堆積和變遷，就形成沖積扇。沖積扇的物質結構，一般是頂部物質較粗，主要為沙、礫 ，隨著水流搬運能力向邊緣減弱，堆積的物質逐漸變細，邊緣一般多為沙、粉沙及亞粘土，分選性較好，所以沖積扇是較好的含水層，邊緣常有泉水出 露，可發(fā)展自流灌 溉。若山地河谷隨山地間歇抬升，也可形成疊置沖積扇。(2)河漫灘平原河漫灘平原發(fā)源于河流中下游。在河流中下游地區(qū)，河流下蝕作用減弱，側蝕作用加強，河流往往凹岸侵蝕，在凸岸堆積形成水下堆積體。堆積體 的面積逐漸擴大，在枯水季節(jié)露出水面，形成河漫灘(見下圖)。

人教版高中地理必修1全球氣候變化教案
科學家預測，就地區(qū)而言，位于低緯度的大部分國家，農作物的產量將減少；而位于高緯度的國家，農作物產量有可能增加。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，導致洪澇、干旱災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。轉折：既然全球變暖會引起很多不利影響，那么作為人類應如何面對這一挑戰(zhàn)呢？這就是我們要討論的第三個問題。板書：三、氣候變化的適應對策討論：請大家閱讀結合教材P53氣候變化的適應對策部分討論人類應如何面對全球變暖這一問題 呢？

新人教版高中英語必修2Unit 1 Cultural Heritage-Discovering Useful Structure教案一
This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3.
