在接下來的細(xì)讀環(huán)節(jié)，我套用了高考對(duì)閱讀理解的考查方式設(shè)置了5個(gè)問題，分別為三個(gè)推理判斷題，一個(gè)細(xì)節(jié)題和一個(gè)主旨大意題。學(xué)生需要對(duì)文章的內(nèi)容進(jìn)行分析、歸納、推理、猜測等高級(jí)思維活動(dòng)才能做出正確的回答?！驹O(shè)計(jì)意圖】這一過程是對(duì)學(xué)生進(jìn)行細(xì)讀的訓(xùn)練，培養(yǎng)學(xué)生獲取特定信息和挖掘文章深層次信息的能力。第三環(huán)節(jié):Intensive-reading (精讀) 15′第三個(gè)環(huán)節(jié)精讀，既是最重要的環(huán)節(jié)，也是突破本課重難點(diǎn)的關(guān)鍵。首先，讓學(xué)生思考劇本中人物看到百萬英鎊前后的態(tài)度發(fā)生了怎樣的變化。其次，讓學(xué)生仔細(xì)閱讀文章，找出可以表現(xiàn)人物態(tài)度變化的具體的語言和動(dòng)作。最后，讓學(xué)生總結(jié)人物的態(tài)度發(fā)生變化的根本原因是什么，從而引出Money Talks, 供學(xué)生思考?！驹O(shè)計(jì)意圖】通過一系列的活動(dòng)培養(yǎng)學(xué)生學(xué)習(xí)從人物的語言和動(dòng)作探究人物的心理，使學(xué)生進(jìn)一步體會(huì)戲劇語言的魅力，從而對(duì)文章背后所反映的社會(huì)問題進(jìn)行思考，也為下一步的討論環(huán)節(jié)做好鋪墊。

分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢(shì)后，就需要針對(duì)由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟(jì)轉(zhuǎn)型，就應(yīng)該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過材料3的相關(guān)內(nèi)容，我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢(shì)產(chǎn)業(yè)、增強(qiáng)綜合競爭力等三個(gè)整改方針上下功夫。因而引導(dǎo)學(xué)生針對(duì)優(yōu)勢(shì)與不足提出建議，以三個(gè)整改方針為基準(zhǔn)，衡量建議的可行性是鍛煉學(xué)生解決此類問題的有效途徑。在此我將教會(huì)學(xué)生的是解決問題方法而非案例的內(nèi)容，正所謂“授之以魚，不如授之以漁”。接下來針對(duì)學(xué)生的建議和教材資料分析所羅列的10點(diǎn)整改思路，由學(xué)生自由發(fā)言提出看法，通過教師的指導(dǎo)和學(xué)生的討論，進(jìn)而確定經(jīng)濟(jì)轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢(shì)相對(duì)照，看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢(shì)而提出的，這樣做會(huì)加深學(xué)生的印象，通過建議和優(yōu)勢(shì)的對(duì)應(yīng)關(guān)系，將不難找出此類問題的解題思路。

人教版高中語文必修5《說“木葉”》教案
【教學(xué)目標(biāo)】Ⅰ、學(xué)習(xí)理解詩歌語言的暗示性特質(zhì)。Ⅱ、根據(jù)詩歌語言的特質(zhì)，進(jìn)行遷移，領(lǐng)略詩歌的精妙之處，給同學(xué)如何鑒賞詩歌提供實(shí)感。㈠、導(dǎo)入：各位同學(xué)，有個(gè)成語叫"一字千金"。對(duì)我而言，第一次領(lǐng)略到一個(gè)字的分量，是在小學(xué)三年級(jí)的時(shí)候，一次作文評(píng)析課上。當(dāng)時(shí)我對(duì)自己的文章充滿了期待，希望能得到老師的贊賞。記得老師進(jìn)來后的第一句話是"有一篇文章，我就沖它用了一個(gè)字，我給它打95分。打這樣的高分，對(duì)我來說，是極為難得的。"同學(xué)都充滿了好奇，老師接著說"這個(gè)字就是一個(gè)'悟'字。我們的同學(xué)都說我學(xué)到了，我明白了，我懂得了一個(gè)道理，而這位同學(xué)卻用了一個(gè)'悟'字，難能可貴。"這篇文章不是我的，在羨慕的同時(shí)，一個(gè)字在文章中的分量就深深的刻在了我的心上。文學(xué)作品中，一個(gè)字精妙與否，足以決定作品是流光溢彩，還是黯然失色。尤其是我們的古典詩詞，用簡短的幾個(gè)字，造就的卻是豐富的情感與博大的意境。讀后滿口余香，卻是妙處難與君說。這跟詩歌的語言是密不可分的。今天，我們就通過《說"木葉"》一文，對(duì)中國古典詩詞語言特質(zhì)作一番探幽。
初中數(shù)學(xué)浙教版七年級(jí)下冊(cè)《第二章 二元一次方程組 三元一次方程組及其解法》教材教案
知識(shí)與技能目標(biāo)：1. 能正確說出三元一次方程（組）及其解的概念，能正確判別一組數(shù)是否是三元一次方程（組）的解；2. 會(huì)根據(jù)實(shí)際問題列出簡單的三元一次方程或三元一次方程組。過程與方法目標(biāo)：1. 通過加深對(duì)概念的理解，提高對(duì)“元”和“次”的認(rèn)識(shí)。2. 能夠逐步培養(yǎng)類比分析和歸納概括的能力，了解辯證統(tǒng)一的思想。情感態(tài)度與價(jià)值觀目標(biāo)：通過對(duì)實(shí)際問題的分析，使學(xué)生進(jìn)一步體會(huì)方程是刻畫現(xiàn)實(shí)世界的有效數(shù)學(xué)模型，培養(yǎng)學(xué)生良好的數(shù)學(xué)應(yīng)用意識(shí)。
（6月5日綠色消費(fèi)日）國旗下講話：環(huán)境與發(fā)展
每年的6月5日是世界環(huán)境日，它的確反映了世界人民對(duì)環(huán)境問題的重視，表達(dá)了人類對(duì)美好環(huán)境的向往和追求。她是聯(lián)合國促進(jìn)全球環(huán)保意識(shí)，提高政府對(duì)環(huán)境問題的關(guān)注所采取的行動(dòng)。地球是人類和其他物種的共同家園，然而由于人類常常采取亂砍濫發(fā)，竭澤而漁等不良發(fā)展方式，地球上物種滅絕的速度大大加快。生物多樣性喪失正使生態(tài)系統(tǒng)滑向不可恢復(fù)的臨界點(diǎn)，如果地球生態(tài)系統(tǒng)最終發(fā)生不可挽回的惡化，人類文明所賴以生存的相對(duì)穩(wěn)定的環(huán)境條件將不復(fù)存在。
