北師大初中九年級(jí)數(shù)學(xué)下冊(cè)利用三角函數(shù)測(cè)高2教案
問題2、如何用測(cè)角儀測(cè)量一個(gè)低處物體的俯角呢?和測(cè)量仰角的步驟是一樣的，只不過(guò)測(cè)量俯角時(shí)，轉(zhuǎn)動(dòng)度盤，使度盤的直徑對(duì)準(zhǔn)低處的目標(biāo)，記下此時(shí)鉛垂線所指的度數(shù)，同樣根據(jù)“同角的余角相等”，鉛垂線所指的度數(shù)就是低處的俯角.活動(dòng)三：測(cè)量底部可以到達(dá)的物體的高度.“底部可以到達(dá)”，就是在地面上可以無(wú)障礙地直接測(cè)得測(cè)點(diǎn)與被測(cè)物體底部之間的距離.要測(cè)旗桿MN的高度，可按下列步驟進(jìn)行：(如下圖)1.在測(cè)點(diǎn)A處安置測(cè)傾器(即測(cè)角儀)，測(cè)得M的仰角∠MCE=α.2.量出測(cè)點(diǎn)A到物體底部N的水平距離AN＝l.3.量出測(cè)傾器(即測(cè)角儀)的高度AC＝a(即頂線PQ成水平位置時(shí)，它與地面的距離).根據(jù)測(cè)量數(shù)據(jù)，就能求出物體MN的高度.在Rt△MEC中，∠MCE=α，AN=EC=l，所以tanα= ，即ME=tana·EC＝l·tanα.又因?yàn)镹E＝AC＝a，所以MN＝ME+EN＝l·tanα+a.

然后，她沿著坡度是i＝1∶1(即tan∠CED＝1)的斜坡步行15分鐘抵達(dá)C處，此時(shí)，測(cè)得A點(diǎn)的俯角是15°.已知小麗的步行速度是18米/分，圖中點(diǎn)A、B、E、D、C在同一平面內(nèi)，且點(diǎn)D、E、B在同一水平直線上．求出娛樂場(chǎng)地所在山坡AE的長(zhǎng)度(參考數(shù)據(jù)：2≈1.41，結(jié)果精確到0.1米)．解析：作輔助線EF⊥AC于點(diǎn)F，根據(jù)速度乘以時(shí)間得出CE的長(zhǎng)度，通過(guò)坡度得到∠ECF＝30°，通過(guò)平角減去其他角從而得到∠AEF＝45°，即可求出AE的長(zhǎng)度．解：作EF⊥AC于點(diǎn)F，根據(jù)題意，得CE＝18×15＝270(米)． ∵tan∠CED＝1，∴∠CED＝∠DCE＝45°.∵∠ECF＝90°－45°－15°＝30°，∴EF＝12CE＝135米．∵∠CEF＝60°，∠AEB＝30°，∴∠AEF＝180°－45°－60°－30°＝45°，∴AE＝2EF＝1352≈190.4(米)．所以，娛樂場(chǎng)地所在山坡AE的長(zhǎng)度約為190.4米．方法總結(jié)：解決本題的關(guān)鍵是能借助仰角、俯角和坡度構(gòu)造直角三角形，并結(jié)合圖形利用三角函數(shù)解直角三角形．

部編版語(yǔ)文七年級(jí)上冊(cè)《古代詩(shī)歌四首》說(shuō)課稿
古詩(shī)詞是初中語(yǔ)文教學(xué)的一個(gè)難點(diǎn)。首先，要注重朗讀，讓學(xué)生通過(guò)反復(fù)朗讀發(fā)現(xiàn)、感受古詩(shī)詞的聲韻之美;其次，要疏通文句，讓學(xué)生準(zhǔn)確理解詩(shī)意，感知形象，但不要求索過(guò)深，而是要避免瑣碎分析，以整體感悟?yàn)橹?最后要提倡背誦積累，還可以鼓勵(lì)學(xué)生動(dòng)手寫一些評(píng)點(diǎn)、賞析文字。學(xué)生在小學(xué)階段學(xué)古詩(shī)文較少，剛升人初中時(shí)要求不宜過(guò)高。要多用啟發(fā)教學(xué)，避免灌輸式教學(xué);可先讓學(xué)生談感受、理解，再落實(shí)到文字。同時(shí)，做好與小學(xué)語(yǔ)文教學(xué)內(nèi)容和教學(xué)方法的銜接也十分必要。要了解學(xué)生小學(xué)階段的學(xué)習(xí)內(nèi)容、學(xué)習(xí)方法、學(xué)習(xí)習(xí)慣等，把學(xué)習(xí)的起點(diǎn)放置在學(xué)生現(xiàn)有的語(yǔ)文基礎(chǔ)上。要充分調(diào)動(dòng)學(xué)生已有的文章積累、語(yǔ)言積累和知識(shí)積累，引導(dǎo)學(xué)生順利地進(jìn)人初中語(yǔ)文學(xué)習(xí)。例如，學(xué)生在小學(xué)學(xué)過(guò)、讀過(guò)李白等人的詩(shī)歌，老師可以喚起學(xué)生的記憶，激發(fā)學(xué)生學(xué)習(xí)的興趣;又如，學(xué)生在小學(xué)習(xí)慣于朗讀，可以利用這一基礎(chǔ)，通過(guò)朗讀引導(dǎo)學(xué)生感受詩(shī)歌，進(jìn)人詩(shī)歌的情境之中。根據(jù)教參的建議，《古代詩(shī)歌四首》課時(shí)安排為2課時(shí)。
