九年級上冊道德與法治文明與家園10作業(yè)設計
( 一) 作業(yè)內容《環(huán)保倡議書》微型討論會一、活動步驟1.對全班同學進行分組，每組設置 1 名小組記錄員。全班選 1 名主持人。 2.主持人致開場白：環(huán)保是對美好生活的向往，有了環(huán)保意識就有前行的力量。 同學們，你們的美麗中國夢想是什么呢？學生代表暢所欲言。3.主持人：每個人都應該有自己建設美麗中國的夢想，那么我們建設美麗的中國 夢想是怎樣呢？4.主持人：有人說，建設美麗中國夢是國家的事、政府的事；也有人說，建設美 麗中國是每個中國人的事；還有人說，建設美麗中國更是我們一代又一代青少年 的事......小組討論并選派小組記錄員代表發(fā)言：談談你們小組是怎樣倡議建設美麗的中國 夢的？5.教師評價與總結。環(huán)保倡議書俗話說靠山吃山靠水吃水，家鄉(xiāng)的山山水水是我們生命的搖籃，但是由于過去不 合理的生產方式對生態(tài)環(huán)境的破壞，子孫后代有可能不能繼續(xù)在這里生存發(fā)展下 去，為了保護和建設美麗家鄉(xiāng)，我向鄉(xiāng)親們建議：
北師大初中數(shù)學九年級上冊反比例函數(shù)1教案
解：（1）根據(jù)題意，可得y＝100025x，化簡得y＝40x；（2）根據(jù)題設可知自變量x的取值范圍為0＜x＜85.方法總結：反比例函數(shù)的自變量取值范圍是全體非零實數(shù)，但在解決實際問題的過程中，自變量的取值范圍要根據(jù)實際情況來確定.解題過程中應該注意對題意的正確理解.三、板書設計反比例函數(shù)概念：一般地，如果兩個變量x，y之間 的對應關系可以表示成y＝kx（k 為常數(shù)，k≠0）的形式，那么稱y 是x的反比例函數(shù)，反比例函數(shù) 的自變量x不能為0確定表達式：待定系數(shù)法建立反比例函數(shù)的模型結合實例引導學生了解所討論的函數(shù)的表達形式，形成反比例函數(shù)概念的具體形象，從感性認識到理性認識的轉化過程，發(fā)展學生的思維.利用多媒體創(chuàng)設大量生活情境，讓學生體驗數(shù)學來源于生活實際，并為生活實際服務，讓學生感受數(shù)學有用，從而培養(yǎng)學生學習數(shù)學的興趣.
北師大初中數(shù)學九年級上冊黃金分割1教案
解析：想要看起來更美，則鞋底到肚臍的長度與身高之比應為黃金比，此題應根據(jù)已知條件求出肚臍到腳底的距離，再求高跟鞋的高度.解：設肚臍到腳底的距離為x m，根據(jù)題意，得x1.60＝0.60，解得x＝0.96.設穿上y m高的高跟鞋看起來會更美，則y＋0.961.60＋y＝0.618.解得y≈0.075，而0.075m＝7.5cm.故她應該穿約為7.5cm高的高跟鞋看起來會更美.易錯提醒：要準確理解黃金分割的概念，較長線段的長是全段長的0.618.注意此題中全段長是身高與高跟鞋鞋高之和.三、板書設計黃金分割定義：一般地，點C把線段AB分成兩條線段AC 和BC，如果ACAB＝BCAC，那么稱線段AB被點 C黃金分割黃金分割點：一條線段有兩個黃金分割點黃金比：較長線段：原線段＝5－12：1 經歷黃金分割的引入以及黃金分割點的探究過程，通過問題情境的創(chuàng)設和解決過程，體會黃金分割的文化價值，在應用中進一步理解相關內容，在實際操作、思考、交流等過程中增強學生的實踐意識和自信心.感受數(shù)學與生活的緊密聯(lián)系，體會數(shù)學的思維方式，增進數(shù)學學習的興趣.
北師大初中數(shù)學九年級上冊黃金分割2教案
2.如何找一條線段的黃金分割點，以及會畫黃金矩形.3.能根據(jù)定義判斷某一點是否為一條線段的黃金分割點.Ⅳ.課后作業(yè)習題4.8Ⅴ.活動與探究要配制一種新農藥，需要兌水稀釋，兌多少才好呢？太濃太稀都不行.什么比例最合適，要通過試驗來確定.如果知道稀釋的倍數(shù)在1000和2000之間，那么，可以把1000和2000看作線段的兩個端點，選擇AB的黃金分割點C作為第一個試驗點，C點的數(shù)值可以算是1000+（2000－1000）×0.618= 1618.試驗的結果，如果按1618倍，水兌得過多，稀釋效果不理想，可以進行第二次試 驗.這次的試驗點應該選AC的黃金分割點D，D的位置是1000+（1618－1000）×0.618，約等于1382，如果D點還不理想，可以按黃金分割的方法繼續(xù)試驗下去.如果太濃，可以選DC之間的黃金分割 點 ；如果太稀，可以選AD之間的黃金分割點，用這樣的方法，可以較快地找到合適的濃度數(shù)據(jù).這種方法叫做“黃金分割法”.用這樣的方法進行科學試驗，可以用最少的試驗次數(shù)找到最佳的數(shù)據(jù)，既節(jié)省了時間，也節(jié)約了原材料.●板書設計
北師大初中數(shù)學九年級上冊反比例函數(shù)2教案
2、某村有耕地346.2公頃，人口數(shù)量n逐年發(fā)生變化，那么該村人均占有耕地面積m（公頃/人）是全村人口數(shù)n的函數(shù)嗎？是反比例函數(shù)嗎？為什么？3、y是x的反比例函數(shù)，下表給出了x與y的一些值： （1）寫出這個反比例函數(shù)的表達式；（2）根據(jù)表達式完成上表。教師巡視個別輔導，學生完畢教師給予評估肯定。II鞏固練習：限時完成課本“隨堂練習”1-2題。教師并給予指導。七、總結、提高。（結合板書小結）今天通過生活中的例子，探索學習了反比例函數(shù)的概念，我們要掌握反比例函數(shù)是針對兩種變化量，并且這兩個變化的量可以寫成 （k為常數(shù)，k≠0）同時要注意幾點：：①常數(shù)k≠0；②自變量x不能為零（因為分母為0時，該式沒意義）；③當 可寫為 時注意x的指數(shù)為—1。④由定義不難看出，k可以從兩個變量相對應 的任意一對對應值的積來求得，只要k確定了，這個函數(shù)就確定了。
北師大初中數(shù)學九年級上冊相似多邊形1教案
（2）如果對應著的兩條小路的寬均相等，如圖②，試問小路的寬x與y的比值是多少時，能使小路四周所圍成的矩形A′B′C′D′和矩形ABCD相似？解析：（1）根據(jù)兩矩形的對應邊是否成比例來判斷兩矩形是否相似；（2）根據(jù)矩形相似的條件列出等量關系式，從而求出x與y的比值.解：（1）矩形A′B′C′D′和矩形ABCD不相似.理由如下：假設兩個矩形相似，不妨設小路寬為xm，則30＋2x30＝20＋2x20，解得x＝0.∵由題意可知，小路寬不可能為0，∴矩形A′B′C′D′和矩形ABCD不相似；（2）當x與y的比值為3：2時，小路四周所圍成的矩形A′B′C′D′和矩形ABCD相似.理由如下：若矩形A′B′C′D′和矩形ABCD相似，則30＋2x30＝20＋2y20，所以xy＝32.∴當x與y的比值為3：2時，小路四周所圍成的矩形A′B′C′D′和矩形ABCD相似.方法總結：因為矩形的四個角均是直角，所以在有關矩形相似的問題中，只需看對應邊是否成比例，若成比例，則相似，否則不相似.

區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句，都叫做主從復合句。賓語從句主要是中考必考的，是初中階段必掌握的從句，賓語從句主要是掌握三要素，所謂賓語從句，就是賓語在主從復合句當中充當賓語的一個句子，叫做賓語從句。主句的謂語動詞是及物動詞，后面如果是詞或者是短語的話，是簡單句，如果是句子的話，肯定是賓語從句。I know that he good at English.就是賓語從句，三要素，一要素是要注意連詞，連詞一共學了三類連詞，一類連詞是that口語當中可以省略，就像剛才說的那一句，I hear he is good at English.還有疑問代詞、疑問副詞，how where when，疑問代詞、疑問副詞。還有一類連詞weather是否的意思，不是狀語從句當中的如果，這一定要和如果區(qū)分開，這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序，要用陳述舉語序。比如說你家有幾口人，我們都說How many people are there in you family?但是這是簡單句，一旦說成賓語從句，你可以告訴我你家有幾口人嗎？Could you tell me how many people there are in you family ?

"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好！歡迎你！請做一下自我介紹。認識一下你的新同學?！蓖ǔＴ谡n上老師會這樣說。你會說什么呢？“噢，不！”與陌生人談話太困難了。但是這也很有意思，并且你還能交到朋友。你該怎么做呢？閑聊。閑聊指得是禮貌的對話?！巴蹰且粋€很棒的乒乓球運動員，不是嗎？”“我希望自己能認識她，你呢？“今年的雨水很多，不是嗎？”反意疑問句是一種禮貌用語。為了使得談話成功，你應該知道怎樣去進行閑聊。你還應該知道與不同的人該談論什么樣的話題。認真的學習這個單元吧，下次在英語課上，你會發(fā)現(xiàn)與大家展開談話是一件很容易的事情，不信我們來試試。)
