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 ?

一、教材分析軸對(duì)稱是現(xiàn)實(shí)生活中廣泛存在的一種現(xiàn)象，本章內(nèi)容定位于生活中軸對(duì)稱現(xiàn)象的分析，全章內(nèi)容按照“直觀認(rèn)識(shí)——探索性質(zhì)——簡(jiǎn)單圖形——圖案設(shè)計(jì)”這一主線展開，而這節(jié)課作為全章的最后一節(jié)，主要作用是將本章內(nèi)容進(jìn)行回顧和深化，使學(xué)生通過折疊、剪紙等一系列活動(dòng)對(duì)生活中的軸對(duì)稱現(xiàn)象由“直觀感受”逐漸過渡到從“數(shù)學(xué)的角度去理解”，最后通過圖案設(shè)計(jì)再將“數(shù)學(xué)運(yùn)用到生活中”。軸對(duì)稱是我們探索一些圖形的性質(zhì),認(rèn)識(shí)、描述圖形形狀和位置關(guān)系的重要手段之一。在后面的學(xué)習(xí)中，還將涉及用坐標(biāo)的方法對(duì)軸對(duì)稱刻畫，這將進(jìn)一步深化我們對(duì)軸對(duì)稱的認(rèn)識(shí)，也為“空間與圖形”后繼內(nèi)容的學(xué)習(xí)打下基礎(chǔ)。二、學(xué)情分析學(xué)生之前已經(jīng)認(rèn)識(shí)了軸對(duì)稱現(xiàn)象，通過扎紙?zhí)剿髁溯S對(duì)稱的性質(zhì)，并在對(duì)簡(jiǎn)單的軸對(duì)稱圖形的認(rèn)識(shí)過程中加深了對(duì)軸對(duì)稱的理解，但是對(duì)生活中的軸對(duì)稱現(xiàn)象仍然以“直觀感受”為主。

4.已知一個(gè)三角形的兩邊長(zhǎng)分別是4cm、7cm，則這個(gè)三角形的周長(zhǎng)的取值范圍是什么？目的:主要是讓學(xué)生掌握三角形三邊的和差關(guān)系具體的應(yīng)用，并能應(yīng)用生活中實(shí)際問題。同學(xué)之間可以合作交流互相探討，發(fā)展學(xué)生空間觀念、推理能力，使學(xué)生善于觀察生活、樂于探索研究，激發(fā)學(xué)生學(xué)習(xí)數(shù)學(xué)的積極性，從中適當(dāng)?shù)膶?duì)學(xué)生進(jìn)行德育教育，教育學(xué)生穿越馬路時(shí)間越長(zhǎng)就越危險(xiǎn)。（五）課堂小結(jié)學(xué)生自我談收獲體會(huì)，說說學(xué)完本節(jié)課的困惑。教師做最終總結(jié)并指出注意事項(xiàng)。目的:讓學(xué)生暢所欲言，談收獲體會(huì)，教師給予鼓勵(lì)。主要是讓學(xué)生熟記新知能應(yīng)用新知解決問題，培養(yǎng)學(xué)生概括總結(jié)的能力、有條理的表達(dá)能力。注意事項(xiàng)為：判斷a，b，c三條線段能否組成一個(gè)三角形，應(yīng)注意：a+b>c,a+c>b,b+c>a三個(gè)條件缺一不可。當(dāng)a是a，b，c三條線段中最長(zhǎng)的一條時(shí)，只要b+c>a就是任意兩條線段的和大于第三邊。

此題的設(shè)計(jì)目的：及時(shí)的練習(xí)一是起到鞏固新知識(shí)的目的，二是及時(shí)了解學(xué)生掌握新知識(shí)的情況，起到反饋的目的。這樣設(shè)計(jì)的依據(jù)是：小題多，是讓更多的學(xué)生參與到學(xué)習(xí)中來，及時(shí)給予他們更正，更多的是對(duì)他們的鼓勵(lì)和表揚(yáng)，有簡(jiǎn)單的題盡量讓基礎(chǔ)不太好的的學(xué)生去說，以讓他們感受到成功的樂趣；并且《新課標(biāo)》中指出課程內(nèi)容應(yīng)處于學(xué)生“最近發(fā)展區(qū)”的范圍以內(nèi)，讓成功始終伴隨學(xué)生學(xué)習(xí)的旅程，以保證學(xué)生不會(huì)因過多的失敗而放棄他們的努力，失去發(fā)展的機(jī)會(huì)。第四環(huán)節(jié)：師生合作，歸納總結(jié)。先由學(xué)生個(gè)人總結(jié)，然后教師補(bǔ)充。設(shè)計(jì)目的：通過學(xué)生個(gè)人小結(jié)，教師可以了解學(xué)生掌握知識(shí)的情況，培養(yǎng)學(xué)生總結(jié)概括的能力，教師補(bǔ)充起到完善所學(xué)知識(shí)的目的。第五環(huán)節(jié)：布置作業(yè)，鞏固提高。設(shè)計(jì)目的：因材施“作業(yè)”，分層次布置作業(yè)，減輕學(xué)生的負(fù)擔(dān)，全面推行素質(zhì)教育，讓學(xué)生學(xué)有用的數(shù)學(xué)，不同的學(xué)生學(xué)習(xí)不同的數(shù)學(xué)，在數(shù)學(xué)中得到不同的發(fā)展，以求彰顯學(xué)生的個(gè)性。
