師:很好。由于存在地球大氣圈、地球水圈和地表的礦物,在地球上這個(gè)合適的溫度條件下,形成了適合于生物生存的自然環(huán)境。人們通常所說的生物,是指有生命的物體,包括植物、動(dòng)物和微生物。據(jù)估計(jì),現(xiàn)有生存的植物約有40萬種,動(dòng)物約有110多萬種,微生物至少有10多萬種。據(jù)統(tǒng)計(jì),在地質(zhì)歷史上曾生存過的生物約有5億~10億種之多,然而,在地球漫長的演化過程中,絕大部分都已經(jīng)滅絕了?,F(xiàn)存的生物生活在巖石圈的上層部分、大氣圈的下層部分和水圈的全部,構(gòu)成了地球上一個(gè)獨(dú)特的圈層,稱為生物圈。生物圈是太陽系所有行星中僅在地球上存在的一個(gè)獨(dú)特圈層。課堂小結(jié):地球所有的外部圈層是相互滲透、相互影響,甚至相互重疊的,在太陽和人類生活的參與下,整個(gè)地球生機(jī)盎然;同時(shí),它們起著保護(hù)地球的作用,可以減弱太陽和宇宙輻射對(duì)地表的影響,減少宇宙中的隕石對(duì)地球表面的撞擊。外部各圈中的物質(zhì)運(yùn)動(dòng)和循環(huán),是促使地表物質(zhì)和形態(tài)演變的重要?jiǎng)恿Α?/p>

【轉(zhuǎn)折過渡】除了以上所說的褶皺山和斷層山之 外,是否還有其他類型的山脈呢?試舉一例說明。【學(xué)生思考后回答】有,如富士山屬于火山?!窘處熆偨Y(jié)】同學(xué)們回答的很好,還有火山,那么火山是如何形成的呢?這就是我們要研究的下一個(gè)問題。【板書】3、火山【指導(dǎo)讀書】請(qǐng)同學(xué)們閱讀教材P81思考:①玄武巖高原和火山有什么聯(lián)系與區(qū)別? ②火山由哪幾部分構(gòu)成的?③火山的規(guī)模是否相同?【學(xué)生回答】①聯(lián)系:玄武巖高原和火山都是由于處于地下深處的巖漿,在巨大的壓力作用下,有時(shí)候會(huì)沿著地殼的薄弱地帶噴出地表而形成的。區(qū)別:玄武巖高原是巖漿沿著地殼的線狀裂隙流出,往往比較寬廣。如哥倫比亞高原?;鹕绞菐r漿沿著地殼的中央噴出口或管道噴出。如我國長白山的主峰。②火山由火山口和火山錐兩部分組成。③火山的規(guī)模大小不一,大火山的相對(duì)高度可達(dá)4 000~5 000米,火山口直徑為數(shù)百米;小火山的相對(duì)高度不及100米。

當(dāng)時(shí),不只發(fā)生了太陽風(fēng)暴,同時(shí)還有其它的現(xiàn)象發(fā)生,導(dǎo)致災(zāi)難巨大。 如果,這些現(xiàn)象單獨(dú)地發(fā)生,結(jié)果就會(huì)是另外一個(gè)樣子。正是由于這些因素綜合起來,1859年的太陽風(fēng)暴,才在人類歷史上留下了濃墨重彩的一筆。太陽磁暴開始干擾通信日本衛(wèi)星首個(gè)被“擊中”日本航天機(jī)構(gòu)29日聲明,受強(qiáng)烈的太陽磁暴影響,28日晚,日本“兒玉(Kodama)”通訊衛(wèi)星信號(hào)中斷。 據(jù)美聯(lián)社報(bào)道,在太陽黑子活動(dòng)減弱后,“兒玉”通訊衛(wèi)星恢復(fù)正常運(yùn)轉(zhuǎn)。 美歐研究人員28日發(fā)布新聞公告稱,太陽當(dāng)天發(fā)生了一次強(qiáng)烈的耀斑爆發(fā),預(yù)示著新一輪太陽風(fēng)暴將在今后一兩天內(nèi)抵達(dá)地球,地球上的通信等設(shè)施可能會(huì)因此受到部分干擾。與這次耀斑爆發(fā)相伴,太陽表面還產(chǎn)生了一股強(qiáng)大的日冕物質(zhì)噴射,方向幾乎直沖地球。研究人員說,噴射產(chǎn)生的帶電粒子流正以約每小時(shí)750萬公里的速度奔地球而來,其與地球磁場(chǎng)作用后可能會(huì)形成比較強(qiáng)烈的地磁暴,使地球兩極出現(xiàn)極光,并可能對(duì)衛(wèi)星運(yùn)行和通信等造成干擾。

過渡:在實(shí)際生活中,城市內(nèi)部空間結(jié)構(gòu)并非完全按照這一經(jīng)濟(jì)規(guī)律呈現(xiàn),而是更具復(fù)雜性。這說明除了經(jīng)濟(jì)因素外,還有很多其他因素在起作用,請(qǐng)大家結(jié)合你的認(rèn)識(shí)、圖2.9和案例1:紐約市的少數(shù)民族區(qū)談?wù)勀愕目捶ā#?)其他因素I收入——形成不同級(jí)別住宅區(qū)的常見原因。有能力支付昂貴租金和選擇最佳居住環(huán)境的人,其居住地往往形成高級(jí)住宅區(qū)。II知名度——城市內(nèi)某些地區(qū)在歷史、文化或經(jīng)濟(jì)方面具有很高的聲譽(yù),這往往會(huì)吸引更多新的住宅或商場(chǎng)建在該處,以提高其知名度。III種族聚居區(qū)的形成——在有些城市的某一區(qū)域內(nèi),如果某個(gè)種族或宗教團(tuán)體占優(yōu)勢(shì),就可能形成種族聚居區(qū)。如紐約市的唐人街、哈林區(qū)、小意大利區(qū)等。IV歷史因素——城市的建筑物和街道設(shè)計(jì)可以維持久遠(yuǎn),早期的土地利用方式對(duì)日后的功能分區(qū)有著深遠(yuǎn)的影響。

一般情況下,凡是支持物對(duì)物體的支持力,都是支持物因發(fā)生形變而對(duì)物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時(shí)發(fā)生微小形變,要恢復(fù)原狀,對(duì)桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對(duì)桌面的壓力;桌面由于發(fā)生微小的形變,對(duì)書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對(duì)書的支持力。學(xué)生分析:靜止地放在傾斜木板上的書,書對(duì)木板的壓力和木板對(duì)書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時(shí),懸繩對(duì)重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時(shí)發(fā)生微小的形變。重物由于發(fā)生微小的形變,對(duì)懸繩產(chǎn)生豎直向下的彈力f1,這是物對(duì)繩的拉力;懸繩由于發(fā)生微小形變,對(duì)物產(chǎn)生豎直向上的彈力f2,這就是繩對(duì)物體的拉力。

1.用CAI課件模擬汽車的啟動(dòng)過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運(yùn)動(dòng),則力對(duì)物體做功的功率保持不變。此情況下,任意一段時(shí)間內(nèi)的平均功率與任一瞬時(shí)的瞬時(shí)功率都是相同的。②很多動(dòng)力機(jī)器通常有一個(gè)額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當(dāng)路面阻力較小時(shí),牽引力也小,速度大,即汽車可以跑得快些;當(dāng)路面阻力較大,或爬坡時(shí),需要比較大的牽引力,速度必須小。這就是爬坡時(shí)汽車換低速擋的道理。③如果動(dòng)力機(jī)器在實(shí)際功率小于額定功率的條件下工作,例如汽車剛剛起動(dòng)后的一段時(shí)間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時(shí)增大,但是這一情況應(yīng)以二者乘積等于額定功率為限度,即當(dāng)實(shí)際功率大于額定功率以后,這種情況不可能實(shí)現(xiàn)。

(五)平拋運(yùn)動(dòng)規(guī)律的應(yīng)用例1:一架老式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機(jī)上投下的炸彈落在停在海面上的敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。分析:對(duì)于這道題我們可以從以下幾個(gè)方面來考慮:(1)從水平飛行的飛機(jī)上投下的炸彈,做什么運(yùn)動(dòng)?為什么?(2)炸彈的這種運(yùn)動(dòng)可分解為哪兩個(gè)什么樣的分運(yùn)動(dòng)?3)要想使炸彈投到指定的目標(biāo)處,你認(rèn)為炸彈落地前在水平方向通過的距離與投彈時(shí)飛機(jī)離目標(biāo)的水平距離之間有什么關(guān)系?拓展:1、式飛機(jī)在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機(jī)上投下的炸彈正好擊中敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點(diǎn),不計(jì)空氣阻力。(1)判斷摩托車能否跨越壕溝?請(qǐng)計(jì)算說明(2)若能跨過,求落地速度?

1、知識(shí)與能力:(1)識(shí)記:20 世紀(jì) 50 ~70 年代國家干預(yù)經(jīng)濟(jì)的政策、 70年代的經(jīng)濟(jì)“滯脹”“混合經(jīng)濟(jì)”;福利國家;第三產(chǎn)業(yè)的蓬勃發(fā)展;“新經(jīng)濟(jì)”的出現(xiàn);(2)理解當(dāng)代資本主義的新變化的實(shí)質(zhì)是資本主義的自我揚(yáng)棄,是在資本主義內(nèi)部的自我改善,是資本主義生產(chǎn)關(guān)系的自我調(diào)整;(3)掌握以美國為代表的主要資本主義國家在戰(zhàn)后的經(jīng)濟(jì)發(fā)展歷程,分析各國經(jīng)濟(jì)發(fā)展的共同原因。2、過程與方法:(1)引導(dǎo)學(xué)生利用教材和相關(guān)史料,培養(yǎng)歸納、再現(xiàn)歷史事件的能力,提高學(xué)生的歷史思維能力;通過討論提高學(xué)生的思辨能力,培養(yǎng)學(xué)生全面客觀地分析問題的思維方式。(2)學(xué)生通過觀察1977年發(fā)達(dá)國家國有經(jīng)濟(jì)比重表,懂得提取有效信息、分析數(shù)據(jù)的能力;(3)學(xué)生通過思考討論西方福利制度的利弊,培養(yǎng)全面、客觀分析和比較歷史現(xiàn)象,辯證地觀察和分析歷史問題的能力。

②其他貨幣與美元掛鉤:即各會(huì)員國貨幣對(duì)美元的匯率按各自貨幣的含金量與美元確定固定比價(jià)。各國貨幣與美元的匯率可按各國貨幣含金量與美元含金量之比來確定,這稱為法定匯率。例如,1946年一英鎊的含金量為3.58134克,一美元的含金量為0.888671克,則英鎊和美元的含金量之比1英鎊=4.03美元就是法定匯率。這一規(guī)定,使美元等同于黃金,美元從此有了“美金”的說法;與美元比起來,其他國家的貨幣處于從屬地位,確立了美元在國際貨幣體系中的中心地位、主導(dǎo)地位正如當(dāng)時(shí)美國財(cái)政部長福勒所說:“各個(gè)行星圍繞著太陽轉(zhuǎn),各國貨幣圍繞著美元轉(zhuǎn)?!毙〗Y(jié): “布雷頓森林體系”是一個(gè)以美元為中心的世界貨幣體系,美國通過布雷頓森林體系,掌握了資本主義世界的經(jīng)濟(jì)命脈。(2)影響:①為世界貨幣關(guān)系提供了統(tǒng)一的標(biāo)準(zhǔn)和基礎(chǔ),有利于維持戰(zhàn)后世界貨幣體系的正常運(yùn)轉(zhuǎn),為世界經(jīng)濟(jì)的恢復(fù)和發(fā)展創(chuàng)造了條件。
