    人教版新課標(biāo)高中地理必修2第一章第三節(jié)人口合理容量教案

    生:環(huán)境承載力是指環(huán)境能持續(xù)供養(yǎng)的人口數(shù)量。師:對了。但是有同學(xué)仍然會感到這是一個很抽象的概念。下面我們具體來了解什么是環(huán)境承載力。我們可以從兩個部分去理解:一、環(huán)境,它主要是指環(huán)境的單個要素(如:土地、水、氣候、植被等。)及其組合方式。二、是承載力,它指在特定的條件下,具體某事物能承受的某種活動的最大值。那環(huán)境承載力的科學(xué)定義是怎樣表達(dá)的呢?生:環(huán)境承載力是指某一時期,某種狀態(tài)條件下,某地區(qū)環(huán)境所能承受的人類活動作用的閾值。師:很對。 我們可以用一個生動的例子來說明。一只木桶里面的水的多少在底面積固定不變的情況下是由哪塊木板來決定?生:最短的那塊。師:確實(shí)如此。這就是我們平常所講的 “木桶效應(yīng)”。那影響環(huán)境承載力的大小也是由環(huán)境個要素里面最緊缺的那個要素來決定的。下面我們用一個例子來印證一下。

    人教版新課標(biāo)高中地理必修2第一章第二節(jié)人口的空間變化教案

    1.促使美國成為一個移民國家的因素是:①美洲屬于未開發(fā)的新大陸,需要大量的勞動力;②歐洲失業(yè)工人和破產(chǎn)農(nóng)民增加,人們?yōu)榱俗非蟾玫慕?jīng)濟(jì)待遇遷往美洲;③新航線的開辟為人們順利遷移掃除了障礙;④殖民擴(kuò)張是人口遷移的促進(jìn)因素,加快了人口遷移的過程。導(dǎo)致美國人口在本土范圍內(nèi)頻繁遷移的原因,歸納起來有:第一次人口遷移是戰(zhàn)爭因素,第二次是城市化;第三次是自然環(huán)境、經(jīng)濟(jì)環(huán)境的變化;第四次是經(jīng)濟(jì)格局的變化,即西部和南部新資源的發(fā)現(xiàn)和新興工業(yè)的發(fā)展。2.我國古代的人口遷移,深受統(tǒng)治者及其行政力量的束縛。封建帝王為了加強(qiáng)本國的經(jīng)濟(jì)和軍事實(shí)力,對人口遷移嚴(yán)加控制。只有當(dāng)戰(zhàn)亂發(fā)生的時候,這種控制才得到削弱,人們?yōu)榱硕惚軕?zhàn)亂,尋找安定的生活環(huán)境,不得不進(jìn)行大規(guī)模的遷移。我國近幾十年的人口遷移主要是由生產(chǎn)資料和勞動力數(shù)量上的地區(qū)分布不平衡造成的,是經(jīng)濟(jì)因素在起主導(dǎo)作用,與古代的人口遷移截然不同。

    1.澳大利亞混合農(nóng)業(yè)地域在生產(chǎn)結(jié)構(gòu)、經(jīng)營方式、科技應(yīng)用、農(nóng)業(yè)專業(yè)化和地域化等方面有哪些特點(diǎn)?2.在澳大利亞混合農(nóng)業(yè)地 域形成的過程中,有哪些區(qū)位因素在起作用?學(xué)生發(fā)言,教師適當(dāng)引導(dǎo)、評點(diǎn)并作講解。[教師提問]:那么,澳大利亞的墨累—達(dá)令盆地的區(qū)位因素有什么不足之處?知識拓展:課件展示澳大利亞大分水嶺的雨影效應(yīng)的形成原理及東水西調(diào)示意圖。[教師講解]:澳大利亞東南部受大分水嶺的影響,降水集中于大分水嶺的東側(cè),在其西側(cè)形成山地的雨影效應(yīng),降水豐富地區(qū)與農(nóng)業(yè)生產(chǎn)地區(qū)分布不一致,灌溉成為澳大利亞農(nóng)牧業(yè)發(fā)展的限制性條件。因此,澳大利亞對水利工程建設(shè)很 重視,東水西調(diào)促進(jìn)了墨累—達(dá)令盆地農(nóng)牧業(yè)的發(fā)展。[課堂小結(jié)]:這節(jié)課我們學(xué)習(xí)了農(nóng)業(yè)區(qū)位選擇的基本原理。 通過學(xué)習(xí)我們了解到,農(nóng)業(yè)的區(qū)位選擇實(shí)質(zhì)上就是對農(nóng)業(yè)土地的合理利用。

    小班幼兒在學(xué)會了區(qū)別“l(fā)”和“許多”的基礎(chǔ)上,可以學(xué)習(xí)比較兩組物體數(shù)量的相等或不相等,即所謂的“一樣多”和“不一樣多”。在比較的過程中通常會運(yùn)用一一對應(yīng)的方法。對應(yīng)一般有兩種(見圖一):重疊對應(yīng)(即將第一組物體從上到下或從左到右排成一行,再把第二組物體一個一個分別疊在第一組物體的上面)。并置對應(yīng)(即把第一組物體排成橫列或豎行.第二組物體一一對應(yīng)分別擺在第一組物體的下方或左、右方)。一一對應(yīng)的內(nèi)容大致可以分為物與物的一一對應(yīng)和物與數(shù)的一一對應(yīng)。比較常見的形式有(見圖二):相關(guān)物體的匹配、數(shù)和量的對應(yīng)匹配、顏色的對應(yīng)、形狀的對應(yīng)、大小的對應(yīng)等。小班第二學(xué)期的幼兒對5以內(nèi)的數(shù)量關(guān)系、物體的明顯特征(顏色、形狀、大小等)、物體簡單的排列(橫排、豎排)以及生活中常見的相關(guān)事物(小兔與蘿卜,小貓與魚等)有了一定的經(jīng)驗(yàn)積累,為進(jìn)行一一對應(yīng)的教學(xué)做了較好的鋪墊。他們對操作性較強(qiáng)的游戲活動較感興趣,一一對應(yīng)的活動正是為幼兒提供了直觀生動的操作機(jī)會,使幼兒在玩一玩、排一排的過程中感知到抽象的數(shù)、物之間的邏輯關(guān)系。

    Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
