人教版新課標高中地理必修2第二章第三節(jié)城市化教案
[補充]：鄭州是特大城市，我們對燈火通明的夜晚都有深刻的體會，我們都體會過光給他們帶來的好處，而對過多過亮的光帶來的危害則很少認真地思考過，且光污染給都市人們和其他生物和環(huán)境帶來的不利影響也越來越大，所以，我在這兒給同學們補充光污染，目的是提醒他們要增強環(huán)保意識，要理解城市在建設過程中要減少城市各類活動對環(huán)境的污染；另外，隨著城市的不斷發(fā)展，還可能會產生新 的污染物。還培養(yǎng)了學生用發(fā)展的眼光來看世界。[思考]：如何降低城市化對地理環(huán)境產生的影響？[答]：發(fā)展生態(tài)城市，使人工環(huán)境和自然環(huán)境和諧統(tǒng)一起來。一方面在城市建設中，要發(fā)展低污染的節(jié)能建筑和綠色交通，減少城市各類活動對環(huán)境的污染；另一方面使城市景觀盡可能地與山、河、湖、海、植被等自然景觀保持協(xié)調，建立一種良性循環(huán)。
人教部編版語文九年級下冊名著導讀《儒林外史》諷刺作品的閱讀教案
“拱一拱手，一屁股就坐在上席”，兩個動作活畫出了夏總甲在鄉(xiāng)民面前的傲慢自大。作者接著寫他的一番話語：“俺如今倒不如你們務農的快活了。想這新年大節(jié)，老爺衙門里，三班六房，那一位不送帖子來。我怎好不去賀節(jié)?每日騎著這個驢，上縣下鄉(xiāng),跑得昏頭暈腦?！薄皬男履赀@七八日，何曾得一個閑?恨不得長出兩張嘴來，還吃不退?！鼻擅畹亟沂玖怂麨楹文恐袩o人和衣服“就如酒簍一般”。二、通過故事情節(jié)的前后對比來表達諷刺。第二回中，周進六十多歲了，還以老童生的身份在薛家集觀音庵教私塾,一年才十二兩館銀，生活窘困，地位低下，村中新中秀才青年梅玖也奚落他。到第七回中，周進中了進士，做了官以后，梅玖就無恥地冒充自己是周進的學生，薛家集的觀音庵里也供起了周進的長生牌位。梅玖見了周進早年寫的一副對聯(lián)，貼在墻上，紅紙都發(fā)白了，竟吩咐和尚用水噴了,剝下來裝裱收藏。這一對比既寫出了周進做官前后迥然不同的境遇，也寫出了秀才梅玖的庸俗勢利以及社會上一些人的趨炎附勢。所以，《儒林外史》的諷刺，不僅僅是對人物的諷刺,更是對當時社會中各種現(xiàn)象的揭露、控訴和批判。
部編版小學語文六年級下冊第20課《真理誕生于一百個問號之后》優(yōu)秀教案范文
1、認真讀課文，邊讀邊想課文每個自然段都寫了什么，給課文劃分段落。2、學生交流段落劃分，說明分段理由。3、教師對照板書進行小結：這篇課文思路特別明晰，作者開門見山提出自己的觀點，明確指出“真理誕生于一百個問號之后”這句話本身就是“真理”，然后概括地指出在千百年來的科學技術發(fā)展史上，那些定理、定律、學說都是在發(fā)現(xiàn)者、創(chuàng)造者解答了“一百個問號之后”才獲得的，由此引出科學發(fā)展史上的三個有代表性的確鑿事例，之后對三個典型事例作結，強調這三個事例“都是很平常的事情”，卻從中發(fā)現(xiàn)了真理，最后指出科學發(fā)現(xiàn)的“偶然機遇”只能給有準備的人，而不會給任何一個懶漢。
部編版小學語文四年級下冊第25課《兩個鐵球同時著地》優(yōu)秀教案范文
1、齊讀第三自然段。思考：亞里士多德講過什么話?伽利略對這話是怎么看的?（亞里士多德說過：“兩個鐵球，一個10磅重，一個1磅重，同時從高處落下來，10磅重的一定先著地，速度是1磅重的10倍?！辟だ詫@話產生了懷疑）2、伽利略為什么懷疑亞里士多德說的話?他是怎么想的?（“他想：如果這句話是正確的，……這怎么解釋呢?”）3、伽利略的分析，是把亞里士多德的話當作兩種假設，推出兩個結論。這兩個結論是什么?（①把一個10磅重，一個1磅重的兩個鐵球拴在一起，如果仍然看作是兩個球，落下的速度應當比原來10磅重的鐵球慢。②如果看做是一個整體，落下的速度，應當比原來10磅重的鐵球快）4.這兩個結果一樣嗎?是什么樣的結果?（不—樣，是相互矛盾的）5.根據同一句話，會推出兩個相互矛盾的結果，所以伽利略認為這句話是靠不住的，值得懷疑。6，他打算怎么做?（用試驗來證明不同重量鐵球落地的情況）

為城市居民提供休養(yǎng)生息的場所，是城市最基本的功能區(qū)．城市中最為廣泛的土地利用方式就是住宅用地．一般住宅區(qū)占據城市空間的40%—60%。（閱讀圖2.3）請同學講解高級住宅區(qū)與低級住宅區(qū)的差別（學生答）（教師總結）（教師講解）另外還有行政區(qū)、文化區(qū)等。而在中小城市，這些部門占地面積很小，或者布局分散，形成不了相應的功能 區(qū)。（教師提問）我們把城市功能區(qū)分了好幾種，比如說住宅區(qū)，是不是土地都是被居住地占據呢？是不是就沒有其他的功能了呢？（學生回答）不是（教師總結）不是的。我們說的住宅區(qū)只是在占地面積上，它是占絕大多數(shù)，但還是有土地是被其它功能占據的，比如說住宅區(qū)里的商店、綠化等也要占據一定的土地， 只是占的比例比較小而已。下面請看書上的活動題。
