人教版高中地理選修2中、低產(chǎn)田的綜合治理教案
一、低濕地的治理與開發(fā)1、 低濕地治理開發(fā)的原因——辛店洼自然條件的主要特點（1）地勢低平：辛店洼洼底海拔17．5米，洼緣海拔19．5米，是全市最低點。（2）漬澇嚴(yán)重：其成因如表6-4所示（3）土質(zhì)好、水源足、水質(zhì)好：成土母質(zhì)為黃河沖積物，土壤質(zhì)地好；水資源豐富，水質(zhì)較好。2、低洼地治理開發(fā)的方法：魚塘——臺田模式（或稱塘田模式）以往辛店洼曾采用挖溝排水的措施治理低洼地，但治理效果不明顯，因為辛店洼的主要矛盾是地勢低洼，地下水位高，挖溝排水因地勢低，排水困難，地下水位難以下降，故治理效果不明顯。20世紀(jì)80年代以來，科學(xué)工作者在辛店洼地區(qū)開始了整治低濕地的研究，他們遵循“因洼制宜”的指導(dǎo)思想，逐步摸索出了低濕地的治理模式：魚塘—--臺田模式
人教版高中地理選修2百萬移民及其安置教案
三峽庫區(qū)農(nóng)村移民安置根本出路是通過發(fā)展大農(nóng)業(yè)來解決耕地不足，不應(yīng)盲目開墾荒坡地，防止產(chǎn)生新的水土流失，盡量避免生態(tài)環(huán)境惡化。2、就地后靠，就近安置模式三峽庫區(qū)淹沒區(qū)線狀分布的受淹特點有別于一般水庫淹沒區(qū)的片狀分布，使得庫區(qū)移民具有相對分散的特點，且淹沒涉及的356個鄉(xiāng)鎮(zhèn)沒有一個被全淹，甚至全淹的村也很少，這有利于移民在本縣甚至本鄉(xiāng)就近后靠安置，避免了水庫移民大量外遷、遠(yuǎn)遷所造成的種種困難和后遺癥。三峽移民搬遷大多可以就地后靠，就近安置，這是三峽移民的一大特色。就近后靠安置的優(yōu)點是不離本鄉(xiāng)本土，移民容易接受，且避免了移民大量外遷、遠(yuǎn)遷所造成的困難和后遺癥；缺點是容易對當(dāng)?shù)氐纳鷳B(tài)環(huán)境造成過大的壓力，如過度開墾坡地、破壞植被、加劇水土流失等。3、工程周期長，可從容安置移民三峽工程建設(shè)周期長（1994年～2009年，共17年），使得移民安置能夠及早進行，可以從容安置移民的生產(chǎn)和生活。

四個同學(xué)為一個合作小組；每個小組利用教師為其準(zhǔn)備的各類三角形，作出它們的高．比一比，看哪一個小組做得最快，發(fā)現(xiàn)的結(jié)論多． 師生行為：學(xué)生操作、討論，教師巡視、指導(dǎo)，使學(xué)生理解【設(shè)計意圖】通過讓學(xué)生操作、觀察、推理、交流等活動，來培養(yǎng)學(xué)生的動手、動腦能力，發(fā)展其空間觀察．活動結(jié)論：1．銳角三角形的三條高都在三角形內(nèi)； 2．直角三角形的一條高在三角形內(nèi)（即斜邊上的高），而另兩條高恰是它的兩條直角邊； 3．鈍角三角形的一條高在三角形內(nèi)，而另兩條高在三角形外．（這是難點，需多加說明） 總之：任何三角形都有三條高，且三條高所在的直線相交于一點．（我們把這一點叫垂心）課堂小結(jié) 1．三角形中三條重要線段：三角形的高、中線和角平分線的概念． 2．學(xué)會畫三角形的高、中線和角平分線．
感受可能性教案教學(xué)設(shè)計
（一）、創(chuàng)設(shè)情景,導(dǎo)入新課摸牌游戲：三位同學(xué)持三組牌，指定三位同學(xué)分別任意摸出一張,看誰能摸到紅牌，他們一定能摸到紅牌嗎?請手持牌的同學(xué)根據(jù)自已手中牌的情況，用語言描述一下抽出紅牌的情況?？偨Y(jié)：在一定條件下，有些事情我們事先能肯定它一定發(fā)生，這些事情成為 事件。有些事情我們事先能肯定它一定不會發(fā)生，這些事情稱為 事件。 事件和 事件統(tǒng)稱為確定事件。許多事情我們事先無法肯定它會不會發(fā)生，這些事情稱為 事件，也稱為 事件。
李商隱詩兩首教學(xué)設(shè)計教案
我們不妨將主旨放在“莊生曉夢迷蝴蝶，望帝春心托杜鵑。滄海月明珠有淚，藍(lán)田日暖玉生煙?！倍?lián)之前，那么，事情就變得簡單起來了：華年如莊生曉夢迷蝴蝶；華年如望帝春心托杜鵑；華年如滄海月明珠有淚；華年如藍(lán)田日暖玉生煙。從課下注釋，我們很容易就可以看出，這四句每一句都在用典。因此，我們通過對典故的解讀，然后加以整理，將其理順，似乎就可以完成對詩歌內(nèi)容的解讀；至于什么悼亡、愛情，不妨拋之腦后，畢竟，沒有那些其他的主題，也并沒有讓詩歌失色，而加上這些捉摸不定的主題，只是讓詩歌增加了所謂的神秘色彩，徒增閱讀難度而已。
