    2.辯證的否定(1)辯證的否定是事物的自我否定。事物內(nèi)部存在著肯定方面和否定方面,它們既對立又統(tǒng)一。最初,肯定方面處于支配地位,否定方面處于被支配地位。在這種情況下,事物就被肯定著。但是,在矛盾雙方的斗爭中,否定方面總會由弱變強(qiáng)。一旦否定方面由被支配地位上升為支配地位,事物就轉(zhuǎn)化到了自己的對立面,實(shí)現(xiàn)了對事物的否定。事物最終之所以被否定,根源在于事物的內(nèi)部,是事物內(nèi)部的否定因素戰(zhàn)勝了肯定因素。因此,事物的否定是自我否定。(2)辯證的否定是事物發(fā)展的環(huán)節(jié)和聯(lián)系的環(huán)節(jié)。所謂發(fā)展,是指新事物的產(chǎn)生和舊事物的滅亡。而實(shí)現(xiàn)這一過程必須要對舊事物進(jìn)行否定,否定實(shí)現(xiàn)了事物由舊質(zhì)向新質(zhì)的飛躍。新事物在否定舊事物時,并不是把舊事物全盤拋棄,一筆勾銷。舊事物是新事物的母體,新事物從舊事物那里脫胎而來,新事物是在批判地繼承舊事物中的一切積極的有生命力的因素的基礎(chǔ)上發(fā)展起來的。這樣,在新舊事物之間就存在著必然的聯(lián)系。

    在數(shù)學(xué)上,0這個數(shù)是解決記數(shù)和進(jìn)位問題而引進(jìn)的概念,由于它不能表示實(shí)在的東西,很長時間人們不把它看作是一個數(shù)。認(rèn)為0是無,是對有的否定。從唯物辯證法的觀點(diǎn)看,這種否定不是形而上學(xué)的簡單否定,而是具有豐富內(nèi)容的辨證否定。辨證的否定是發(fā)展的環(huán)節(jié)。0是從無到有的必經(jīng)之路,是連接無和有的橋梁。0又是正數(shù)和負(fù)數(shù)之間的界限,它既否定了任何正數(shù),也否定了任何負(fù)數(shù),是唯一的中性數(shù)。但它又是聯(lián)結(jié)正數(shù)和負(fù)數(shù)的中間環(huán)節(jié)。沒有0,負(fù)數(shù)就過渡不到正數(shù)去,正數(shù)也休想發(fā)展到負(fù)數(shù)來。數(shù)學(xué)中的0是對任何定量的否定。如果沒有這一否定,任何量的發(fā)展都無從談起。這個否定不是一筆勾銷,而是揚(yáng)棄。因?yàn)樗朔巳魏味康挠邢扌?,成為其發(fā)展的環(huán)節(jié)。在現(xiàn)實(shí)生活中,0作為辨證的否定,也體現(xiàn)出聯(lián)系和發(fā)展的性質(zhì)。如0度不是沒有溫度,而是非常確定的溫度。

    一、教材分析作為世界觀,辯證法昭示我們,世界是一個永不停息地運(yùn)動、變化和發(fā)展的世界;作為一種思維方法,辯證法要求我們以批判精神和創(chuàng)新意識對待周圍的世界。把握唯物辯證法的革命批判精神和辯證否定觀的基本內(nèi)涵,有助于我們自覺樹立創(chuàng)新意識,有助于我們堅持解放思想、實(shí)事求是、與時俱進(jìn)。二、教學(xué)目標(biāo)1、知識目標(biāo):熟記:創(chuàng)新的社會作用;理解:創(chuàng)新的社會作用從幾個角度分析的,如何分析的。2、能力目標(biāo):學(xué)會用創(chuàng)新的知識分析和認(rèn)識事物的能力;通過學(xué)習(xí)辨證法的革命批判精神,使學(xué)生初步形成批判性思維,初步具 有在認(rèn)識世界和改造世界的活動中逐步培養(yǎng)和形成自己的革命批判精神的能力和創(chuàng)新能力。3、情感態(tài)度和價值觀目標(biāo):使學(xué)生堅信創(chuàng)新是唯物辨證法的根本要求,創(chuàng)新意識的哲學(xué)基礎(chǔ)是唯物辨證法的否定觀和唯物辨證法的革命批判精神

    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。

    在經(jīng)濟(jì)水平較高、工業(yè)地域規(guī)模較大的地區(qū),其發(fā)展?jié)摿瓦h(yuǎn)不一樣,如鋼鐵工業(yè)。鋼鐵工業(yè)的生產(chǎn)過程比較復(fù)雜(如課本圖5.31),需要有相互接近的工廠,不僅包括從事鋼鐵生產(chǎn)各道工序的工廠,如燒結(jié)廠、焦化廠、煉鐵廠、煉鋼廠、軋鋼廠,還包括與鋼鐵生產(chǎn)有聯(lián)系的工廠,如氧氣廠、機(jī)修廠、發(fā)電廠、水泥廠等,總共可達(dá)20~30個工廠。這些工廠集 聚,設(shè)備大,管線長,占地多。因此,這樣形成的工業(yè)地域(鋼鐵工業(yè)區(qū))面積廣,發(fā)育程度高,發(fā)展?jié)摿Υ?。這類工業(yè)地域 再加上為方便眾多工人生活所配置的服務(wù)業(yè)和其他工業(yè),在發(fā)展過程中,往往由于工業(yè)地域的擴(kuò)展而形成工業(yè)城市。例如,我國的鞍山(“鋼都”)、攀枝花、馬鞍山、包頭(“草原鋼城”)等鋼鐵工業(yè)城市的形成。除此之外,石油化工區(qū)、機(jī)械制造工業(yè)區(qū)等屬于發(fā)育程度高的工業(yè)地域,也往往擴(kuò)展而形成工業(yè)城市。例如,我國的石油城大慶、克拉瑪依,汽車城十堰等。
