二、說教學(xué)目標(biāo)：由于本單元的五個(gè)話題都涉及到了不同的條件下所產(chǎn)生的各種結(jié)果。所以我確定的本課時(shí)的教學(xué)目標(biāo)是：通過談?wù)搱D片和身邊常見的話題，學(xué)會(huì)if引導(dǎo)的條件狀語從句的用法。即用if條件狀語從句作出假設(shè)，用will來談?wù)摻Y(jié)果。三、說教學(xué)重點(diǎn)：一方面，由于本單元的話題是談?wù)摻Y(jié)果，那么在不同的情境下其結(jié)果也會(huì)不一樣，所以根據(jù)不同的情境來推測(cè)并談?wù)摳鞣N結(jié)果是個(gè)重點(diǎn)。另一方面，因?yàn)閷W(xué)生沒有一個(gè)好的語言氛圍，所以我側(cè)重于聽力和口語的培養(yǎng)，多創(chuàng)設(shè)情境能讓學(xué)生發(fā)揮想象，以此激發(fā)他們的學(xué)習(xí)興趣，。四、說教學(xué)難點(diǎn)學(xué)生容易記住主句用一般將來時(shí)態(tài)，從句用一般現(xiàn)在時(shí)態(tài)，但在判斷主句、從句方面容易混淆，因此，我將正確使用主句從句的時(shí)態(tài)定為本課時(shí)的難點(diǎn)。

1． 教材的地位及作用：本單元圍繞談?wù)撨^去的經(jīng)歷，學(xué)習(xí)使用現(xiàn)在完成時(shí)態(tài)。通過對(duì)學(xué)生們喜聞樂見的一些娛樂場(chǎng)所（fun places）的描述，反復(fù)運(yùn)用句型Have you ever been to…? I’ve never been to…. 來激發(fā)他們使用本單元所學(xué)單詞的興趣。教材中提供的所有活動(dòng)都以現(xiàn)在完成時(shí)態(tài)為中心，通過一系列的聽、說、讀、寫的訓(xùn)練，來加深對(duì)現(xiàn)在完成時(shí)態(tài)的理解，明白英漢兩種在結(jié)構(gòu)及表達(dá)方法的一些異同點(diǎn)。從而提高他們運(yùn)用所學(xué)語言的綜合能力。2． 教材的結(jié)構(gòu)本單元分Section A 和Section B 兩部分。Section A 中通過所設(shè)計(jì)的各項(xiàng)任務(wù)呈現(xiàn)了兩篇聽力課文和一篇閱讀理解。Section B則安排了一篇聽力和兩篇小短文，用以加強(qiáng)對(duì)目標(biāo)語言的理解。Self Check 部分是用來檢查學(xué)生對(duì)本單元所學(xué)目標(biāo)語言的綜合運(yùn)用能力。單元后的語篇訓(xùn)練旨在通過目標(biāo)語言培養(yǎng)學(xué)生的閱讀理解能力，掌握一些基本的閱讀技巧。3． 教學(xué)目標(biāo)（知識(shí)目標(biāo)、能力目標(biāo)、情感目標(biāo)）

北師大初中數(shù)學(xué)九年級(jí)上冊(cè)黃金分割2教案
2.如何找一條線段的黃金分割點(diǎn)，以及會(huì)畫黃金矩形.3.能根據(jù)定義判斷某一點(diǎn)是否為一條線段的黃金分割點(diǎn).Ⅳ.課后作業(yè)習(xí)題4.8Ⅴ.活動(dòng)與探究要配制一種新農(nóng)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(yàn)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(gè)端點(diǎn)，選擇AB的黃金分割點(diǎn)C作為第一個(gè)試驗(yàn)點(diǎn)，C點(diǎn)的數(shù)值可以算是1000+（2000－1000）×0.618= 1618.試驗(yàn)的結(jié)果，如果按1618倍，水兌得過多，稀釋效果不理想，可以進(jìn)行第二次試 驗(yàn).這次的試驗(yàn)點(diǎn)應(yīng)該選AC的黃金分割點(diǎn)D，D的位置是1000+（1618－1000）×0.618，約等于1382，如果D點(diǎn)還不理想，可以按黃金分割的方法繼續(xù)試驗(yàn)下去.如果太濃，可以選DC之間的黃金分割 點(diǎn) ；如果太稀，可以選AD之間的黃金分割點(diǎn)，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(jìn)行科學(xué)試驗(yàn)，可以用最少的試驗(yàn)次數(shù)找到最佳的數(shù)據(jù)，既節(jié)省了時(shí)間，也節(jié)約了原材料.●板書設(shè)計(jì)
北師大初中數(shù)學(xué)九年級(jí)上冊(cè)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(gè)反比例函數(shù)的表達(dá)式；（2）根據(jù)表達(dá)式完成上表。教師巡視個(gè)別輔導(dǎo)，學(xué)生完畢教師給予評(píng)估肯定。II鞏固練習(xí)：限時(shí)完成課本“隨堂練習(xí)”1-2題。教師并給予指導(dǎo)。七、總結(jié)、提高。（結(jié)合板書小結(jié)）今天通過生活中的例子，探索學(xué)習(xí)了反比例函數(shù)的概念，我們要掌握反比例函數(shù)是針對(duì)兩種變化量，并且這兩個(gè)變化的量可以寫成 （k為常數(shù)，k≠0）同時(shí)要注意幾點(diǎn)：：①常數(shù)k≠0；②自變量x不能為零（因?yàn)榉帜笧?時(shí)，該式?jīng)]意義）；③當(dāng) 可寫為 時(shí)注意x的指數(shù)為—1。④由定義不難看出，k可以從兩個(gè)變量相對(duì)應(yīng) 的任意一對(duì)對(duì)應(yīng)值的積來求得，只要k確定了，這個(gè)函數(shù)就確定了。

2．已知：如圖 ，在△ABC中，∠C＝90°， CD為中線，延長(zhǎng)CD到點(diǎn)E，使得 DE＝CD．連結(jié)AE，BE，則四邊形ACBE為矩形嗎？說明理由。答案：四邊形ACBE是矩形.因?yàn)镃D是Rt△ACB斜邊上的中線，所以DA=DC=DB,又因?yàn)镈E=CD，所以DA=DC=DB=DE,所以四邊形ABCD是矩形（對(duì)角線相等且互相平分的四邊形是矩形）。四、課堂檢測(cè)：1．下列說法正確的是（ ）A.有一組對(duì)角是直角的四邊形一定是矩形 B.有一組鄰角是直角的四邊形一定是矩形C.對(duì)角線互相平分的四邊形是矩形 D.對(duì)角互補(bǔ)的平行四邊形是矩形2. 矩形各角平分線圍成的四邊形是（ ）A.平行四邊形 B.矩形 C.菱形 D.正方形3. 下列判定矩形的說法是否正確（1）有一個(gè)角是直角的四邊形是矩形 （ ）（2）四個(gè)角都是直角的四邊形是矩形 （ ）（3）四個(gè)角都相等的四邊形是矩形 （ ） （4）對(duì)角線相等的四邊形是矩形 （ ）（5）對(duì)角線相等且互相垂直的四邊形是矩形 （ ）（6）對(duì)角線相等且互相平分的四邊形是矩形 （ ）4. 在四邊形ABCD中，AB=DC，AD=BC.請(qǐng)?jiān)偬砑右粋€(gè)條件，使四邊形ABCD是矩形.你添加的條件是 .(寫出一種即可)
