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(fù)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(fù)合句當(dāng)中充當(dāng)賓語的一個(gè)句子，叫做賓語從句。主句的謂語動(dòng)詞是及物動(dòng)詞，后面如果是詞或者是短語的話，是簡(jiǎn)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(xué)了三類連詞，一類連詞是that口語當(dāng)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(dāng)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(jiǎn)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 ?

北師大版初中數(shù)學(xué)八年級(jí)下冊(cè)一元一次不等式與一次函數(shù)說課稿2篇
由于任何一個(gè)一元一次不等式都能寫成ax+b>0（或<0）的形式，而此式的左邊與一次函數(shù)y=ax+b的右邊一致，所以從變化與對(duì)應(yīng)的觀點(diǎn)考慮問題，解一元一次不等式也可以歸結(jié)為兩種認(rèn)識(shí)：⑴從函數(shù)值的角度看，就是尋求使一次函數(shù)y=ax+b的值大于（或小于0）的自變量x的取值范圍。⑵從函數(shù)圖像的角度看，就是確定直線y=ax+b在x軸上（或下）方部分所有的點(diǎn)的橫坐標(biāo)所構(gòu)成的集合。教學(xué)過程中，主要從以上兩個(gè)角度探討一元一次不等式與一次函數(shù)的關(guān)系。1、“動(dòng)”―――學(xué)生動(dòng)口說，動(dòng)腦想，動(dòng)手做，親身經(jīng)歷知識(shí)發(fā)生發(fā)展的過程。2、“探”―――引導(dǎo)學(xué)生動(dòng)手畫圖，合作討論。通過探究學(xué)習(xí)激發(fā)強(qiáng)烈的探索欲望。3、“樂”―――本節(jié)課的設(shè)計(jì)力求做到與學(xué)生的生活實(shí)際聯(lián)系緊一點(diǎn)，直觀多一點(diǎn)，動(dòng)手多一點(diǎn)，使學(xué)生興趣高一點(diǎn)，自信心強(qiáng)一點(diǎn)，使學(xué)生樂于學(xué)習(xí)，樂于思考。4、“滲”―――在整個(gè)教學(xué)過程中，滲透用聯(lián)系的觀點(diǎn)看待數(shù)學(xué)問題的辨證思想。

教學(xué)目標(biāo)：1．會(huì)畫直棱柱（僅限于直三棱柱和直四棱柱）的三種視圖，體會(huì)這幾種幾何體與其視圖之間的相互轉(zhuǎn)化。2. 會(huì)根據(jù)三視圖描述原幾何體。教學(xué)重點(diǎn)：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(xué)難點(diǎn)：幾何體與視圖之間的相互轉(zhuǎn)化。培養(yǎng)空間想像觀念。課型：新授課教學(xué)方法：觀察實(shí)踐法一、實(shí)物觀察、空間想像觀察：請(qǐng)同學(xué)們拿出事先準(zhǔn)備好的直三棱柱、直四棱柱，根據(jù)你所擺放的位置經(jīng)過 想像，再抽象出這兩個(gè)直棱柱的主視圖，左視圖和俯視圖。繪制：請(qǐng)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(gè)幾何體的主視圖、左視圖和俯視圖，你認(rèn)為他畫的對(duì)不對(duì)？談?wù)勀愕目捶?。拓展：?dāng)你手中的兩個(gè)直棱柱擺放的角度變化時(shí)，它們的三種視圖是否會(huì)隨之改變？試一試。

四、范例學(xué)習(xí)、理解領(lǐng)會(huì)例2 某校墻邊有甲、乙兩根木桿。已知乙木桿的高度為1.5m.（1）某一時(shí)刻甲木桿在陽光下的影子如圖5-6所示，你能畫出此時(shí)乙木桿的影子嗎？（用線段表示影子）(2)在圖中，當(dāng)乙木桿移動(dòng)到什么位置時(shí)，其影子剛好不落在墻上？（3）在(2)的情況下,如果測(cè)得甲、乙木桿的影子長分別為1.24m和1m,那么你能求出甲木桿的高度嗎?學(xué)生畫圖、 實(shí)驗(yàn)、觀察、探索。五、隨堂練習(xí)課本隨堂練習(xí) 學(xué)生觀察、畫圖、合作交流。六、課堂總結(jié)本節(jié)課通過各種實(shí)踐活動(dòng)，促進(jìn)大家對(duì)內(nèi)容的理解，本課內(nèi)容，要體會(huì)物體在太陽光下形成的不同影子，在操作中觀察不 同時(shí)刻影子的方向和大小變化特征。在同一時(shí)刻,物體的影子與它們的高度成比 例.
