If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die. If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.

北師大初中數(shù)學九年級上冊復雜圖形的三視圖2教案
教學目標：1．會畫直棱柱（僅限于直三棱柱和直四棱柱）的三種視圖，體會這幾種幾何體與其視圖之間的相互轉化。2. 會根據(jù)三視圖描述原幾何體。教學重點：掌握直棱柱的三視圖的畫法。能根據(jù)三視圖描述原幾何體。教學難點：幾何體與視圖之間的相互轉化。培養(yǎng)空間想像觀念。課型：新授課教學方法：觀察實踐法一、實物觀察、空間想像觀察：請同學們拿出事先準備好的直三棱柱、直四棱柱，根據(jù)你所擺放的位置經過 想像，再抽象出這兩個直棱柱的主視圖，左視圖和俯視圖。繪制：請你將抽象出來的三種視圖畫出來，并與同伴交流。比較：小亮畫出了其中一個幾何體的主視圖、左視圖和俯視圖，你認為他畫的對不對？談談你的看法。拓展：當你手中的兩個直棱柱擺放的角度變化時，它們的三種視圖是否會隨之改變？試一試。
北師大初中數(shù)學九年級上冊復雜圖形的三視圖1教案
解析：熟記常見幾何體的三種視圖后首先可排除選項A，因為長方體的三視圖都是矩形；因為所給的主視圖中間是兩條虛線，故可排除選項B；選項D的幾何體中的俯視圖應為一個梯形，與所給俯視圖形狀不符.只有C選項的幾何體與已知的三視圖相符.故選C.方法總結：由幾何體的三種視圖想象其立體形狀可以從如下途徑進行分析：（1）根據(jù)主視圖想象物體的正面形狀及上下、左右位置，根據(jù)俯視圖想象物體的上面形狀及左右、前后位置，再結合左視圖驗證該物體的左側面形狀，并驗證上下和前后位置；（2）從實線和虛線想象幾何體看得見部分和看不見部分的輪廓線.在得出原立體圖形的形狀后，也可以反過來想象一下這個立體圖形的三種視圖，看與已知的三種視圖是否一致.探究點四：三視圖中的計算如圖所示是一個工件的三種視圖，圖中標有尺寸，則這個工件的體積是（）A.13πcm3 B.17πcm3C.66πcm3 D.68πcm3解析：由三種視圖可以看出，該工件是上下兩個圓柱的組合，其中下面的圓柱高為4cm，底面直徑為4cm；上面的圓柱高為1cm，底面直徑為2cm，則V＝4×π×22＋1×π×12＝17π（cm3）.故選B.

故最少由9個小立方體搭成，最多由11個小立方體搭成；（3）左視圖如右圖所示.方法點撥：這類問題一般是給出一個由相同的小正方體搭成的立體圖形的兩種視圖，要求想象出這個幾何體可能的形狀.解答時可以先由三種視圖描述出對應的該物體，再由此得出組成該物體的部分個體的個數(shù).三、板書設計視圖概念：用正投影的方法繪制的物體在投影 面上的圖形三視圖的組成主視圖：從正面得到的視圖左視圖：從左面得到的視圖俯視圖：從上面得到的視圖三視圖的畫法：長對正，高平齊，寬相等由三視圖推斷原幾何體的形狀通過觀察、操作、猜想、討論、合作等活動，使學生體會到三視圖中位置及各部分之間大小的對應關系.通過具體活動，積累學生的觀察、想象物體投影的經驗，發(fā)展學生的動手實踐能力、數(shù)學思考能力和空間觀念.

1、數(shù)數(shù)格子，認清方向（完成想想做做第1題）設計意圖：本題在于讓學生認清平移的方向和距離，感受平移的不同方法。在教學中，讓學生自己獨立思考完成，自由發(fā)言。鼓勵學生說出不同的平移方法。2、小試牛刀（完成想想做做第2題）設計意圖：本題主要是讓學生掌握按要求畫平移后的圖形。這是本節(jié)課的難點。在教學中，先讓學生獨立畫圖，教師巡視作圖情況，對有困難的學生給予指導。在學生完成作圖后，投影部分學生的作品，交流平移的過程與方法。最后在多媒體課件上展示畫法。.3、平移的運用(“想想做做”第3題)設計意圖：本題在于使學生學會運用平移的知識畫平行線，體會平移的價值。（四）課堂小結，升華提高提問：今天你有哪些收獲?設計意圖：以問題為載體，引領學生對本節(jié)課的歸來總結。讓學生再次理解圖形的斜向平移可轉換成橫向平移和豎向平移。
北師大版初中數(shù)學九年級上冊圖形的放大與縮小說課稿
說教學難點：圖形的放大與縮小的原理是“大小改變，形狀不變“。針對小學生的年齡和認知特點，教材中“圖形的放大與縮小”從對應邊的比相等來進行安排，而對應角的不變也是形狀不變必備的條件，是學生體會圖形的相似所必需的。學生在學習的過程中很有可能會質疑到這一問題。（為什么直角三角形只需要同時把兩條直角邊放大與縮??？）所以我把“學生在觀察、比較、思考和交流等活動中，感受圖形放大、縮小，初步體會圖形的相似。（對應邊的比相等，對應角不變）”做為本節(jié)課的難點。說教法、學法：通過直觀演示，情景激趣，結合生活讓學生形成感性認識；引導學生經過觀察、猜想、分析、操作、質疑、小組交流、合作學習、驗證等過程形成理性認識。教學過程：（略）
