And this part ( listening and speaking ) is divided into two parts: Part A---share views on historic sites, Part B ---talk about a visit to a historic tourist destination. By talking with a foreigner, the speakers introduce the historic attractions and their cultures. Part A is that William, a British student, who was going to visit the Confucius Temple and a Chinese student, Xiao Kong, who was going to the Confucius Temple to meet with the members of the research group, went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts.

（1）宗教有它自身的發(fā)展規(guī)律，不能簡(jiǎn)單的用行政力量去消滅或發(fā)展宗教，實(shí)行宗教信仰自由政策是遵循宗教發(fā)展規(guī)律，科學(xué)處理宗教問題。（2）宗教信仰自由是憲法賦予公民的民主權(quán)利，實(shí)行宗教信仰自由政策有利于加強(qiáng)信教群眾與不信教群眾的團(tuán)結(jié)，引導(dǎo)宗教與社會(huì)主義社會(huì)相適應(yīng)。2、弘揚(yáng)科學(xué)精神我國(guó)是在馬列主義、毛澤東思想、鄧小平理論、三個(gè)代表重要思想指引下的社會(huì)主義國(guó)家，要建設(shè)社會(huì)主義物質(zhì)文明、政治文明，也要建設(shè)社會(huì)主義精神文明。加強(qiáng)對(duì)人民群眾的科學(xué)世界觀和無(wú)神論教育，形成文明、健康、崇尚科學(xué)的社會(huì)風(fēng)尚，逐步消除宗教存在的社會(huì)根源何認(rèn)識(shí)根源，在保護(hù)宗教信仰自由的同時(shí)，創(chuàng)造宗教消亡的條件，這是解決在教問題的根本途徑。3、中學(xué)生作為中國(guó)特色社會(huì)主義事業(yè)未來(lái)的建設(shè)者，要用辯證唯物主義和歷史主義以及現(xiàn)代科學(xué)文化知識(shí)武裝自己，弘揚(yáng)科學(xué)精神，樹立科學(xué)世界觀，承擔(dān)起建設(shè)祖國(guó)、振興中華的光榮歷史使命。

（一）知識(shí)目標(biāo)識(shí)記：宗教信仰自由的含義。理解：（1）社會(huì)主義條件下宗教存在的長(zhǎng)期性；（2）理解我國(guó)實(shí)行宗教信仰自由的內(nèi)容；（3）依法加強(qiáng)對(duì)宗教事務(wù)管理的有關(guān)規(guī)定。（4）積極引導(dǎo)宗教與社會(huì)主義社會(huì)相適應(yīng)。（二）能力目標(biāo)能運(yùn)用馬克思主義關(guān)于宗教的基本觀點(diǎn)，分析說(shuō)明我國(guó)實(shí)行宗教信仰自由的正確性和必要性。（三）情感、態(tài)度與價(jià)值觀目標(biāo)通過學(xué)習(xí)，加強(qiáng)宗教的政策觀念，自覺抵制和反對(duì)各種迷信活動(dòng)，特別是認(rèn)清法輪功的邪教本質(zhì)。三、教學(xué)重點(diǎn)難點(diǎn)全面理解和貫徹宗教信仰自由政策既是重點(diǎn)又是難點(diǎn)，教學(xué)中緊緊抓住中央一再?gòu)?qiáng)調(diào)的三句話：（1）全面貫徹宗教政策；（2）加強(qiáng)對(duì)宗教事務(wù)管理：（3）引導(dǎo)宗教與社會(huì)主義社會(huì)相適應(yīng)。四、學(xué)情分析這是本課的難點(diǎn)。我國(guó)是多民族的國(guó)家，也是多宗教的國(guó)家，特別是宗教對(duì)一些少數(shù)民族有廣泛而深遠(yuǎn)的影響。我們東部地區(qū)的學(xué)生，很多人還存在疑惑：我們社會(huì)主義國(guó)家為什么還允許宗教存在，實(shí)行宗教信仰自由政策呢？

人教版高中歷史必修2古代的經(jīng)濟(jì)政策教案
【本課小結(jié)】本課主要講述了古代中國(guó)土地制度的發(fā)展情況。明清的資本主義萌芽，是中國(guó)封建社會(huì)內(nèi)部產(chǎn)生的新生事物。但資本主義萌芽受到的封建王朝“重農(nóng)抑商”和“閉關(guān)鎖國(guó)”政策的阻礙。正是這種“閉關(guān)鎖國(guó)”與“重農(nóng)抑商”政策相結(jié)合，導(dǎo)致了資本主義萌芽的緩慢發(fā)展，并使中國(guó)與世隔絕，不能及時(shí)學(xué)習(xí)西方先進(jìn)的科學(xué)技術(shù)，使中國(guó)落后于世界潮流，從而埋下了日后落后挨打的禍根?！局悄苡?xùn)練】閱讀下列材料：材料一自耕農(nóng)是封建國(guó)家直接剝削的對(duì)象。為了保證賦稅、徭役的供應(yīng)，封建國(guó)家歷來(lái)關(guān)注這一階層的存在?！胺€(wěn)定小農(nóng)”是封建王朝長(zhǎng)治久安的良策，每一個(gè)新王朝建立時(shí)，對(duì)此尤為關(guān)注。他們總是采取鼓勵(lì)墾荒等政策，積極培植自耕農(nóng)。誠(chéng)然，自耕農(nóng)這一階層是很不穩(wěn)定的，經(jīng)常分化。
人教版高中歷史必修2古代手工業(yè)的進(jìn)步教案
①原因：封建制度的衰落（根本原因）【合作探究】清朝資本主義萌芽緩慢發(fā)展的原因。提示：①封建所有制的束縛。殘酷的封建剝削使農(nóng)民赤貧如洗，無(wú)力購(gòu)買手工業(yè)品，限制了手工業(yè)產(chǎn)品的銷路。封建地租的剝削率很高，又驅(qū)使地主和商人把他們的錢財(cái)用于購(gòu)買土地，影響資本主義手工業(yè)的擴(kuò)大再生產(chǎn)。②.封建政府的壓制。清政府實(shí)行重農(nóng)抑商的政策，采取了許多妨礙手工業(yè)生產(chǎn)和資本主義萌芽發(fā)展的措施，主要的有：實(shí)行閉關(guān)政策，嚴(yán)格限制海外貿(mào)易；在國(guó)內(nèi)廣設(shè)關(guān)卡，對(duì)商品征收重稅；嚴(yán)格控制手工業(yè)的生產(chǎn)規(guī)模，如建立受官府控制的行會(huì)，制定行規(guī)限制雇工人數(shù)、產(chǎn)品品種、控制原料分配，限制產(chǎn)品銷售的價(jià)格和地區(qū)范圍等。②發(fā)展的表現(xiàn)：具有資本主義萌芽的部門和地區(qū)增多。（參見教材P10“學(xué)思之窗”）
人教版高中歷史必修2古代商業(yè)的發(fā)展教案
中國(guó)古代商業(yè)的發(fā)展有哪些表現(xiàn)？綜觀中國(guó)古代歷史，商業(yè)在不同的歷史時(shí)期有不同的表現(xiàn)。主要表現(xiàn)在：（1）商業(yè)活動(dòng)的場(chǎng)所的變化：先主要在城市中進(jìn)行，后來(lái)農(nóng)村集市貿(mào)易逐漸發(fā)展。唐時(shí)加快，明清時(shí)突出，出現(xiàn)了專業(yè)性的市集（如絲市、葉市、豬市等），以至逐漸形成了新興的市鎮(zhèn)（有的更是專業(yè)性的集散市集）；而不是先有農(nóng)村商業(yè)，而后才有城市商業(yè)的發(fā)展。（2）交易內(nèi)容的變化：商業(yè)開始時(shí)以販運(yùn)、交流地區(qū)間的土特產(chǎn)品，經(jīng)營(yíng)統(tǒng)治者所需要的奢侈品為主要內(nèi)容，以后隨著商品貨幣經(jīng)濟(jì)的發(fā)展，市場(chǎng)商品種類增多、行業(yè)分細(xì)，為一般人民所需要的主要農(nóng)副產(chǎn)品以及城市手工業(yè)所生產(chǎn)的大小商品在整個(gè)流通界地位提高。這種情況在宋代已經(jīng)顯現(xiàn)。（3）交易媒介的變化：商品交換最原始的形態(tài)是物物交換，不存在交易的媒介。隨著商品交換的內(nèi)容和地域的擴(kuò)大，出現(xiàn)了以貝殼等為代表的一般等價(jià)物。

人教版新課標(biāo)高中物理必修2功率教案2篇
1．用CAI課件模擬汽車的啟動(dòng)過程。師生共同討論：①如果作用在物體上的力為恒力，且物體以勻速運(yùn)動(dòng)，則力對(duì)物體做功的功率保持不變。此情況下，任意一段時(shí)間內(nèi)的平均功率與任一瞬時(shí)的瞬時(shí)功率都是相同的。②很多動(dòng)力機(jī)器通常有一個(gè)額定功率，且通常使其在額定功率狀態(tài)工作（如汽車），根據(jù)P=FV可知：當(dāng)路面阻力較小時(shí)，牽引力也小，速度大，即汽車可以跑得快些；當(dāng)路面阻力較大，或爬坡時(shí)，需要比較大的牽引力，速度必須小。這就是爬坡時(shí)汽車換低速擋的道理。③如果動(dòng)力機(jī)器在實(shí)際功率小于額定功率的條件下工作，例如汽車剛剛起動(dòng)后的一段時(shí)間內(nèi)，速度逐漸增大過程中，牽引力仍可增大，即F和v可以同時(shí)增大，但是這一情況應(yīng)以二者乘積等于額定功率為限度，即當(dāng)實(shí)際功率大于額定功率以后，這種情況不可能實(shí)現(xiàn)。

（五）平拋運(yùn)動(dòng)規(guī)律的應(yīng)用例1：一架老式飛機(jī)在高出海面45m的高處，以80m/s的速度水平飛行，為了使飛機(jī)上投下的炸彈落在停在海面上的敵船，應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。分析：對(duì)于這道題我們可以從以下幾個(gè)方面來(lái)考慮：(1)從水平飛行的飛機(jī)上投下的炸彈，做什么運(yùn)動(dòng)?為什么?(2)炸彈的這種運(yùn)動(dòng)可分解為哪兩個(gè)什么樣的分運(yùn)動(dòng)?3)要想使炸彈投到指定的目標(biāo)處，你認(rèn)為炸彈落地前在水平方向通過的距離與投彈時(shí)飛機(jī)離目標(biāo)的水平距離之間有什么關(guān)系?拓展：1、式飛機(jī)在高出海面45m的高處，以80m/s的速度水平飛行，尾追一艘以15m/s逃逸的敵船，為了使飛機(jī)上投下的炸彈正好擊中敵船，應(yīng)該在與轟炸目標(biāo)的水平距離為多遠(yuǎn)的地方投彈?不計(jì)空氣阻力。2、在一次摩托車跨越壕溝的表演中，摩托車從壕溝的一側(cè)以速度v＝40m/s沿水平方向向另一側(cè)，壕溝兩側(cè)的高度及寬度如圖所示，摩托車可看做質(zhì)點(diǎn)，不計(jì)空氣阻力。（1）判斷摩托車能否跨越壕溝？請(qǐng)計(jì)算說(shuō)明（2）若能跨過，求落地速度？
