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)。

人教版高中語文必修3《登高》教案2篇
【設(shè)計(jì)思想】詩歌教學(xué)的關(guān)鍵是感受詩景，體味詩情，領(lǐng)悟詩意，在此基礎(chǔ)上孕育理解能力、鑒賞能力和審美情感。詩景、詩情、詩意均由文字來承載，把握文字組合的張力，是讀詩賞詩的抓手。杜甫的詩歌素以煉字精深、涵蓋深遠(yuǎn)著稱，以《登高》而言，往往淡淡一字，平平一語，便籠大千于方寸，縮古今于一瞬。故細(xì)讀文本，咀嚼字句，便是賞景、悟情、會(huì)意的基本路徑。其次，不朽名作的特點(diǎn)是寄寓深廣，古今評(píng)價(jià)甚多，見仁見智，不一而足。這正是培養(yǎng)學(xué)生問題意識(shí)、探究意識(shí)的極好憑借。第三，詩為語言之精華，是詩人心里涌出的情感之流。誦讀乃賞詩之要著，精心感悟之時(shí)，設(shè)身處地，心惟口誦，是理解詩意的關(guān)鍵一步。基于是，筆者作如下同課異構(gòu)，殊途同歸?！窘虒W(xué)目標(biāo)】1．理解本詩所繪之景、所抒之情及繪景、抒情之法。2．學(xué)會(huì)用意象疊加法、字句推敲法、誦讀體驗(yàn)法等欣賞詩歌。3．感受杜甫心系蒼生、情寄邦國、憂國憂民、兼濟(jì)天下的博大情懷。

一、引入：教師列舉以下言論，讓學(xué)生辨出哪些是孟子的，哪些不是。學(xué)生不知道的，由教師說出。學(xué)生不理解的，教師作簡(jiǎn)要解說。1.天將降大任于是人也，必先苦其心志，勞其筋骨，餓其體膚，空乏其身，行拂亂其所為。所以動(dòng)心忍性，曾益其所不能。（孟子）2.域民不以封疆之界，固國不以山溪之險(xiǎn)，威天下不以兵革之利。得道者多助，失道者寡助。（孟子）3.魚，亦我所欲也，熊掌，亦我所欲也，二者不可得兼，舍魚而取熊掌者也。生，亦我所欲也，義，亦我所欲也，二者不可得兼，舍生而取義者也。（孟子）4.富貴不能淫，貧賤不能移，威武不能屈。（孟子）5.非禮勿視，非禮勿聽，非禮勿言，非禮勿動(dòng)。（孔子）6.無惻隱之心非人也，無羞惡之心非人也，無辭讓之心非人也，無是非之心非人也。（孟子）7.庖有肥肉，廄有肥馬，民有饑色，野有餓殍。（孟子）8.人性之善也，猶水之就下也；人無有不善，水無有不下。（孟子）9.民為貴，社稷次之，君為輕。（孟子）10.君子坦蕩蕩，小人常戚戚。（孔子）
