人教版高中地理必修1冷熱不均引起的大氣運動教案
討論：二氧化碳在大氣的受熱過程中起到了什么作用？（吸收太陽輻射中的紅外線輻射和地面輻射，保溫作用）大氣中的二氧化碳濃度增大對氣溫有什么影響？（全球氣候變暖）閱讀：我們知道了太陽輻射中的可見光和紅外 光能量的吸收和轉化，那么紫外區(qū)的能量到哪兒去了？請同學們查閱資料，自主探討。小結：大氣的受熱過 程就是太陽曬熱了地面，地面烘熱了大氣。太陽輻射是大氣的根本熱源，地面輻射是大氣的直接熱源。這就是為什么海拔越高，氣溫越低的原因，難怪高處不勝寒！轉承：大氣的直接熱源是地面，不同性質的地面溫度是不同的，同緯度，海洋和陸地就有溫差。提問：請學生說說白天和晚上在海邊的不同感受。由白天和晚上的風向不同切入實驗P32活動。討論：通過煙霧的飄動，我們得出了什么規(guī)律？冷熱不均引起了熱力環(huán)流板書： 二、熱力環(huán)流板圖與分析：結合試驗，學生分析熱力環(huán)流 的產(chǎn)生
人教版高中地理必修1第四章第一節(jié)營造地表形態(tài)的力量教案
晶晶和亮亮是兩滴巖漿，他們生活在地球內(nèi)部的：巖漿之家。一天，他們得到批準，與其他同伴一起到地球表面進行旅行。他們飛快地奔向地表，半路上，晶晶覺得累了，于是就與亮亮約好，在地表匯合。亮亮沒有停步，與其他伙伴一起跳出地表，并沿著山坡往低處流動。忽然，亮亮發(fā)現(xiàn)自己不能再動了，不禁問旁邊的同伴這是怎么一回事。同伴笑著說：“別擔心，只不過你已經(jīng)不再是巖漿罷了?！眴栴}1、為什么同伴說亮亮已經(jīng)不再是一滴巖漿了？2、你認為亮亮還可以繼續(xù)他的地表旅行嗎？請說明原因。（由學生討論回答。）過了好長的一段時間，亮亮發(fā)現(xiàn)自己的個頭變小了，并隨著風和流水往前運動了。亮亮邊走邊欣賞著地表美麗的風光。忽然，亮亮發(fā)現(xiàn)一個熟悉的身影，認真一看，原來是晶晶。亮亮驚訝地問：“你是怎么來到地表的？”3、請你簡要推測晶晶到達地表的過程。（由學生討論回答。）亮亮和晶晶又一起踏上旅程。
人教版高中地理必修1營造地表形態(tài)的力量教案
【導入新課】一位在青藏高原上跋涉的旅行者，途中休息時從路邊巖層中隨手拿起一塊小石 頭玩賞時受小石子的紋路的吸引，他不禁仔細觀瞧，吃驚地發(fā)現(xiàn)這竟是一個古代海洋生物化石！近年來，人們在臺灣海 峽海底某些地方發(fā)現(xiàn)有古代森林的遺跡。這些發(fā)現(xiàn)告訴我們什么？ 【學生討論回答】略。 【教師總結概括】地殼和宇宙間一切物質一樣，處在不停的運動變化之中。那么地表千姿百態(tài)的形態(tài)是如何營造的呢？這就是我們這節(jié)課要解決的課題【板書】第四章：地表形態(tài)的塑造 第一節(jié)：營造地表形態(tài)的力量【提問】哪位同學能夠例舉營造地表形態(tài)的力量改變地表面貌的實例？ （學生討論、回答問題。教師在副板書上一一記錄。） 【過渡】營造地表形態(tài)的力量具體劃分有很多種，但歸納起來看可以劃分為兩種，即內(nèi)力作用和外力作用，首先我們來看一下內(nèi)力作用．【板書】一、內(nèi)力作用 【指導讀書】請大家閱讀教材Ｐ74第一段和案例1，思考：
人教版高中地理必修1自然地理環(huán)境的整體性教案
1．生產(chǎn)功能：合成有機物的能力2．平衡功能：使自然地理要素的性質保持穩(wěn)定的能力【教師講解】生產(chǎn)功能主要依賴于光合作用。在光合作用過程中，植物提供葉綠素，大氣提供熱量和二氧化碳，土壤及水圈、巖石圈提供水分及無機鹽。光合作用通過物質和能量的交換，將生物、大氣、水、土壤、巖石等地理要素統(tǒng)一在一起，在一定的條件下，生產(chǎn)出有機物。由此可見，生產(chǎn)功能是自然環(huán)境的整體功能而非單個地理要素的功能。大氣本身不具有減緩二氧化碳增加的功能，但是，在自然地理環(huán)境中，通過各地理要素的相互作用，卻能消除部分新增的二氧化碳的能力，既為自然地理環(huán)境的平衡功能。請大家閱讀教材P94活動，利用平衡功能的原理，解釋一定范圍內(nèi)各物種的數(shù)量基本恒定這一現(xiàn)象。【學生討論回答】略。（可參考教參）【轉折】自然地理環(huán)境各要素每時每刻都在演化，如我們熟知的氣候變化、地貌變化等。各個要素的發(fā)展演化是統(tǒng)一的，一個要素的演化伴隨著其他各個要素的演化。
人教版高中地理必修3地理環(huán)境對區(qū)域發(fā)展的影響教案
(1)下面列出的是我國南北方傳統(tǒng)民居的差異，分析形成這些差異的自然原因：——北方民居正南正北的方位觀比南方強；——北方民居的墻體嚴實厚重，南方民居的墻體輕??；——從北到南，民居的屋頂坡度逐漸增大，房檐逐漸加寬，房屋進深和高度逐漸加大。(2)下面列出的是我國南北方城市住宅摟的差異，分析導致這些差異的自然原因：——如果不考慮地價、建筑材料等因素，建同等面積的住房，北方的建筑成本比南方高 ；——建同樣高度的多幢樓房，北方樓房的南北間距比南方大。點撥：本活動要求學生了解由于地理環(huán)境的差異造成南北方建筑物特點的不同，并由此認識地理環(huán)境 差異對人們生活的影響。（1）比較而言，北方的冬季寒冷而漫長，南方的夏季濕熱而漫長。為了在冬季充分利用太陽光照和熱量，北方民居正南正北的方位觀比南方強。北方民居的墻體嚴實厚重，利用在冬季保溫御寒；南方民居的墻體輕薄，利于在夏季通風透氣。從北到南，年降水量逐漸增大，民居的屋頂坡度也逐漸增大（利于排水） ；隨著對保溫要求的降低和對通風納涼要求的提高，民居的屋檐逐漸加寬，房屋進深和高度逐漸加大。
人教版高中地理必修3第四章第二節(jié)區(qū)域工業(yè)化與城市化教案
從右圖“進出口貿(mào)易占全國的比重”可看出，珠三角地區(qū)的外向型經(jīng)濟特征很明顯，但正在緩慢的發(fā)生轉變；而長三角地區(qū)的外貿(mào)依存度在10年內(nèi)迅速增長。由此可見，珠三角地區(qū)城市化過程，是伴隨著該地特殊的經(jīng)濟發(fā)展相對自發(fā)地快速推進，缺乏宏觀而理性的規(guī)劃。閱讀通過此閱讀材料，使學生大致了解以下內(nèi)容深圳作為珠江三角洲地區(qū)迅速城市化的一個典型代表，到目前為止，對其未來發(fā)展道路的構想，主要集中在：如何聯(lián)合和依托臨近區(qū)域、聯(lián)合優(yōu)勢資源，擴大發(fā)展空間；如何明確功能，重新定位，合理分工，突出特色?；顒娱L江三角洲地區(qū)城市的協(xié)調(diào)發(fā)展1．讀圖4．28，如果按人口規(guī)模>500萬人、100萬～500萬人、50萬～100萬人、20萬～50萬人和<20萬人將城市分為五級的話，分析長江三角洲地區(qū)城市的等級規(guī)模結構是否合理，這對其城市的協(xié)調(diào)發(fā)展有何影響?
人教版高中地理必修3第四章第一節(jié)區(qū)域農(nóng)業(yè)發(fā)展教案
1．根據(jù)下面的材料，歸納珠江三角洲發(fā)展基塘生產(chǎn)有利的地理條件。珠江三角洲地勢低平，河網(wǎng)密布，降水充沛。北回歸線從珠江三角洲的北部穿過。桑樹和甘蔗主要分布于熱帶和亞熱帶。廣州是古代海上絲綢之路的起始地之一。水產(chǎn)品在廣東人的食物結構中占有較大的比重。點撥珠江三角洲地區(qū)發(fā)展基塘農(nóng)業(yè)生產(chǎn)有利條件可以結合材料，歸納為三個方面：地形、氣候、市場（當?shù)睾秃Ｍ猓┚唧w分析略。2．圖4．16所示的基塘生產(chǎn)將哪些產(chǎn)業(yè)聯(lián)系起來?哪些副產(chǎn)品(或廢棄物)被充分利用起來?這種聯(lián)系對農(nóng)村經(jīng)濟發(fā)展有什么作用?點撥基塘生產(chǎn)環(huán)節(jié)將種植業(yè)（桑、蔗等）、養(yǎng)殖業(yè)（養(yǎng)蠶、養(yǎng)魚）、工業(yè)（絲廠、糖廠）等幾種產(chǎn)業(yè)緊密的聯(lián)系在一起。在此環(huán)節(jié)中，塘泥、蠶沙（蠶屎）、蠶蛹、繅絲、濾泥、蔗葉等副產(chǎn)品被充分的回收利用。養(yǎng)蠶業(yè)、蔗糖加工業(yè)同塘魚養(yǎng)殖業(yè)緊密結合，作為一種綜合的經(jīng)營，幾者之間相互依存、相互促進、揚長補短，有機地循環(huán)聯(lián)系起來。
人教版高中地理必修3第五章第一節(jié)資源的跨區(qū)域調(diào)配教案
2．通過西氣東輸輸送到上海的天然氣，價格只相當于進口天然氣的3／4、同等熱值煤氣的 2／3。你認為是否應該提高天然氣的價格，以促進西部的發(fā)展。點撥：可以從不同方面分析。⑷對環(huán)境的影響①有利于改善東部地區(qū)的大氣質量據(jù)監(jiān)測顯示，在同等熱值的情況下，與煤炭相比，利用天然氣作燃料幾乎不產(chǎn)生二氧化硫、粉塵等污染物質，氮氧化物和二氧化碳的排放量也大為減少。長江三角洲地區(qū)的能源長期高度依賴煤炭，例如，上海市煤炭消費量占能源消費總量的70％。從西部地區(qū)輸送來的天然氣，可以部分替代煤炭。②為了最大限度減少對沿線地區(qū)生態(tài)環(huán)境的影響，西氣東輸工程在建設過程中，嚴格環(huán)境保護的要求。③在沿線農(nóng)村地區(qū)推廣使用天然氣，可減少農(nóng)民對薪柴的需求，從而緩解因植被破壞而帶來的環(huán)境壓力。

人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.
