人教版高中地理必修1第二章第四節(jié)全球氣候變化教案
氣候變化對(duì)健康的影響 氣候變化對(duì)人體健康的不良影響是不難發(fā)現(xiàn)的：熱浪沖擊頻繁加重可致死亡率及某些疾病、特別是心臟呼吸系統(tǒng)疾病發(fā)病率增加；對(duì)氣候變化敏感的傳染性疾病如瘧疾和登革熱的傳播范圍可能增加。極端氣候事件, 如干旱、水災(zāi)、暴風(fēng)雨等, 使死亡率、傷殘率及傳染病疾病率上升, 并增加社會(huì)心理壓力。某些媒介疾病的加重也可能與氣候變化有間接的關(guān)系, 如瘧疾是通過(guò)蚊子傳播的疾病,氣候變化可能使某些變暖地區(qū)的蚊子數(shù)目增加, 從而加重了瘧疾的發(fā)生。我國(guó)1994年瘧疾的發(fā)病率為5.3408/10萬(wàn), 居全國(guó)法定傳染病的第六位。血吸蟲(chóng)病的發(fā)展與高溫及灌溉系統(tǒng)的擴(kuò)增有關(guān)。我國(guó)1994年南方12省市血吸蟲(chóng)病患者的檢出率高達(dá)3.67%，不能忽視氣候變化對(duì)此的可能影響。還有一些疾病，如睡眠病、登革熱、黑熱病等也有與氣候關(guān)系的報(bào)道。另外, CO2、一些空氣污染物如氮氧化物、臭氧等可增加過(guò)敏疾患及心臟呼吸系統(tǒng)疾病和死亡。

1．生產(chǎn)上的聯(lián)系：有投入——產(chǎn)出的關(guān)系工業(yè)生產(chǎn)的過(guò)程復(fù)雜，工序繁多，往往需要經(jīng)過(guò)多家工廠的加工才能完成一種產(chǎn)品的生產(chǎn)過(guò)程。因此，在這些工廠之間就存在著產(chǎn)品與原料的聯(lián)系。一家工廠生產(chǎn)的產(chǎn)品是另一家工廠的原料，這兩家工廠之間就形成了工序上的工業(yè)聯(lián)系。2．非生產(chǎn)上的聯(lián)系：如地理空間上的聯(lián)系布局在同一個(gè)工業(yè)區(qū)內(nèi)，共同利用工業(yè)區(qū)的道路、供水、供電、通信等基礎(chǔ)設(shè)施以及其他生產(chǎn)、生活服務(wù)設(shè)施，或者共同利用當(dāng)?shù)亓畠r(jià)的勞動(dòng)力，形成了空間利用上的工業(yè)聯(lián)系。我國(guó)許多地方的經(jīng)濟(jì)技術(shù)開(kāi)發(fā)區(qū)就是建立在這種工業(yè)聯(lián)系基礎(chǔ)上的。（二）工業(yè)集聚1．形成具有工業(yè)聯(lián)系的一些工廠往往近距離地聚集起來(lái)，形成工業(yè)集聚現(xiàn)象。2．工業(yè)集聚可獲得效應(yīng)（1）工業(yè)集聚可以加強(qiáng)企業(yè)間的信息交流和技術(shù)協(xié)作，降低中間產(chǎn)品的運(yùn)輸費(fèi)用和能源消耗，進(jìn)而降低生產(chǎn)成本，提高生產(chǎn)效率和利潤(rùn)，取得規(guī)模效益。
人教版高中語(yǔ)文必修5《說(shuō)“木葉”》教案
【教學(xué)目標(biāo)】Ⅰ、學(xué)習(xí)理解詩(shī)歌語(yǔ)言的暗示性特質(zhì)。Ⅱ、根據(jù)詩(shī)歌語(yǔ)言的特質(zhì)，進(jìn)行遷移，領(lǐng)略詩(shī)歌的精妙之處，給同學(xué)如何鑒賞詩(shī)歌提供實(shí)感。㈠、導(dǎo)入：各位同學(xué)，有個(gè)成語(yǔ)叫"一字千金"。對(duì)我而言，第一次領(lǐng)略到一個(gè)字的分量，是在小學(xué)三年級(jí)的時(shí)候，一次作文評(píng)析課上。當(dāng)時(shí)我對(duì)自己的文章充滿了期待，希望能得到老師的贊賞。記得老師進(jìn)來(lái)后的第一句話是"有一篇文章，我就沖它用了一個(gè)字，我給它打95分。打這樣的高分，對(duì)我來(lái)說(shuō)，是極為難得的。"同學(xué)都充滿了好奇，老師接著說(shuō)"這個(gè)字就是一個(gè)'悟'字。我們的同學(xué)都說(shuō)我學(xué)到了，我明白了，我懂得了一個(gè)道理，而這位同學(xué)卻用了一個(gè)'悟'字，難能可貴。"這篇文章不是我的，在羨慕的同時(shí)，一個(gè)字在文章中的分量就深深的刻在了我的心上。文學(xué)作品中，一個(gè)字精妙與否，足以決定作品是流光溢彩，還是黯然失色。尤其是我們的古典詩(shī)詞，用簡(jiǎn)短的幾個(gè)字，造就的卻是豐富的情感與博大的意境。讀后滿口余香，卻是妙處難與君說(shuō)。這跟詩(shī)歌的語(yǔ)言是密不可分的。今天，我們就通過(guò)《說(shuō)"木葉"》一文，對(duì)中國(guó)古典詩(shī)詞語(yǔ)言特質(zhì)作一番探幽。

人教版新課標(biāo)高中物理必修2功率教案2篇
1．用CAI課件模擬汽車(chē)的啟動(dòng)過(guò)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(chē)），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(chē)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(chē)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(chē)剛剛起動(dòng)后的一段時(shí)間內(nèi)，速度逐漸增大過(guò)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)。
