    人教版高中地理必修3荒漠化的防治教案

    1.薩赫勒地區(qū)位于撤哈拉沙漠的南緣。請根據(jù)下面的圖文資料,并聯(lián)系已學知識,分析薩赫勒地區(qū)的氣候等自然特征,并說明荒漠化的潛在自然因素。點撥:資料表明薩林勒地區(qū)正處于干旱與半干旱、熱帶沙漠與熱帶草原的過渡地帶;津德爾是其中有代表性的居民點,其月均溫都在22℃以上,甚至達到33℃,可想而知其蒸發(fā)量是巨大的。在降水方面,這里的年降水量不足500毫米,且基本集中在夏季,特別是7、8兩個月。以其有限的而且特別集中的降水狀況與其全年的高溫、高蒸發(fā)量相比,確實是個容易產(chǎn)生環(huán)境問題的敏感地區(qū)。客觀上,這里就潛在著荒漠化的自然因素,這是本地區(qū)的地理位置和當?shù)氐乃疅釛l件所決定的。2.氣候的嚴酷性決定了薩赫勒地區(qū)的傳統(tǒng)經(jīng)濟以自給性質(zhì)的游牧業(yè)為主。20世紀以來,隨著沿岸國家人口和經(jīng)濟的發(fā)展及本區(qū)交通條件的改善,這里的傳統(tǒng)游牧經(jīng)濟向商品性的定居牧業(yè)經(jīng)濟轉(zhuǎn)化。

    劉邦:先看劉邦對項伯的表白(此話也是有意讓項伯轉(zhuǎn)述給項羽聽的):“秋毫不敢有所近”——說“不敢”而不說“不曾”,多么恭順!“籍吏民,封府庫,而待將軍”——“待”,多么虔誠!“日夜望將軍至”——說“望”而不說“等”,多么迫切!再看劉邦的卑詞“謝罪”:他言必稱“將軍”,說自己與項羽“戮力而攻秦”,是戰(zhàn)友而非敵人;將“先入關破秦”說成是不自意,以表自己的力量不如項羽;把“得復見將軍于此”當作是自己莫大的榮幸以滿足項羽的虛榮心;最后,他還把項羽的憤怒歸咎于“小人”的挑撥,為項羽推卸責任,及時給項羽一個臺階下。小結:項羽:沽名釣譽、輕敵自大、寡謀輕信、不善用人、剛愎自用、優(yōu)柔寡斷的一介武夫。劉邦:狡詐多謀、遇事果斷、臨危不懼、能屈能伸、善于用人。

    3、介紹對聯(lián)的歷史引出本課的重點。人類歷史上的第一副對聯(lián)是“新年納余慶,嘉節(jié)號長春”。出現(xiàn)在五代十國時期(公元964年),距離現(xiàn)在已經(jīng)有1044年了。有著一千多年歷史的對聯(lián)有什么基本的特點呢?這是我們這節(jié)課學習的重點。請在座的各位當回醫(yī)生,給下面這幅對聯(lián)號號脈,看它對仗是否工整?上聯(lián):冬去春來千條楊柳迎風綠下聯(lián):冰消雪化梅花萬朵撲鼻有什么問題,怎么改?剛才這幾位同學指出了這幅對聯(lián)的兩個問題,也提出了兩條修改意見。第一是下聯(lián)少了一個字,最好是添加一個“香”字;第二是下聯(lián)的“梅花萬朵”與上聯(lián)的“千條楊柳”是數(shù)量詞對名詞,名詞對數(shù)量詞,對仗不工整,要調(diào)整為“萬朵梅花”。這樣,數(shù)量詞“萬朵”對“千條”,名詞“梅花”對“楊柳”。大家還有沒有不同的看法。這樣我們就可以得出對聯(lián)的兩個特點特點:第一個特點是上下聯(lián)字數(shù)要相等(板書)。就是上聯(lián)有幾個字,下聯(lián)也要有幾個字。大家記下來,對聯(lián)基本要求一,“上下聯(lián)字數(shù)相等”。這個要求是很嚴格的,一般來說,違反這個規(guī)則就不成對聯(lián)了。

    ①從政府人員組成看,南京政府是一個以資產(chǎn)階級革命派為主體的政府。②從政府頒發(fā)的法令和措施看,這些法令體現(xiàn)了資產(chǎn)階級民主革命的要求,對于發(fā)展民族資本主義經(jīng)濟、資產(chǎn)階級民主政治和文化教育以及改革社會風氣,都起了積極作用。③從頒布的《中華民國臨時約法》看,憲法體現(xiàn)了三權分立的政治體制,體現(xiàn)了資產(chǎn)階級民主主義的要求,是中國歷史上第一部資產(chǎn)階級民主憲法,具有反封建專制制度的進步意義。(2)從南京臨時政府的內(nèi)外政策分析南京政府的根本弱點①未徹底地反封建。它沒有采取比較徹底的反對封建主義的措施,特別是對封建統(tǒng)治的基礎——地主階級土地所有制沒有觸動,這樣,南京臨時政府也就不能真正地把廣大人民群眾動員起來,因而缺乏真正的群眾基礎。
