人教版高中地理必修3森林的開發(fā)和保護(hù)教案
角色扮演：學(xué)生扮演政府官員、熱帶叢林土著居民、 世界環(huán)保組織官員、開發(fā)商等角色，從角色的立場(chǎng)討論亞馬孫河流域熱帶雨林的開發(fā)活動(dòng)規(guī)則: 每個(gè)小組認(rèn)領(lǐng)一種角色，用5分鐘的時(shí)間討論和整理思路，然后推薦一位代表做中心發(fā)言，小組的其他同學(xué)可以隨時(shí)補(bǔ)充。發(fā)言時(shí)請(qǐng)說(shuō) 明所扮演的角色，盡可能多的發(fā)表建設(shè)性意見(jiàn)。如果需要，可以上臺(tái)展示材料【學(xué)生互動(dòng)】 風(fēng)云辯論：雨林破壞誰(shuí)之錯(cuò)?正方觀點(diǎn)：雨林破壞，亞馬孫地區(qū) 的國(guó)家和 居民應(yīng)負(fù)主要責(zé)任反方觀點(diǎn): 雨林破壞，發(fā)達(dá)國(guó)家應(yīng)負(fù)主要責(zé)任 【師生小結(jié)】 雨林的開發(fā)，既有發(fā)展中國(guó)家經(jīng)濟(jì)的需要，也有發(fā)達(dá)國(guó)家國(guó)際市場(chǎng)的牽動(dòng)。保護(hù)雨林，是全人類的共同責(zé)任，尤其發(fā)達(dá)國(guó)家應(yīng)該承擔(dān)更多的責(zé)任。保護(hù)亞馬遜雨林符合長(zhǎng)遠(yuǎn)利益和全球利益。但這與雨林所在地國(guó)家的發(fā)展產(chǎn)生了矛盾，如何解決之一矛盾是雨林開發(fā)與保護(hù)的關(guān)鍵?！具^(guò)渡承轉(zhuǎn)】 綠色和平組織警告說(shuō)，如果不采取有效措施制止對(duì)森林的破壞，80年內(nèi)熱帶雨林可能完全從地球上消失。開發(fā)還是保護(hù)?這是雨林的兩種前途，也
