在當(dāng)時(shí)雅典的公民大會(huì)和陪審法庭上，人們常常要發(fā)表意見，要和自己的對(duì)手辯論，雅典法庭規(guī)定每個(gè)公民須替自己辯護(hù)，不許旁人代辯。所以出現(xiàn)了這樣一批專門教授人辯論、演說、修辭的技巧和參政知識(shí)的職業(yè)教師。①政治因素：雅典奴隸制民主政治發(fā)展到頂峰，成為希臘政治和文化中心。參與政治生活成為每個(gè)公民生活的重要內(nèi)容②古希臘工商業(yè)發(fā)展，奴隸制經(jīng)濟(jì)繁榮（在廣大奴隸的勞動(dòng)基礎(chǔ)上，古希臘的經(jīng)濟(jì)迅速發(fā)展起來(lái)，為哲學(xué)的成長(zhǎng)提供了物質(zhì)條件）——根本原因③人的地位的提高（民主政治制度和每個(gè)公民參與政治意識(shí)的加強(qiáng)，使人的中心地位日益突出）最后教師強(qiáng)調(diào)：提示并強(qiáng)調(diào)學(xué)生學(xué)習(xí)時(shí)要注意理解“一定的文化是一定社會(huì)的政治和經(jīng)濟(jì)在觀念形態(tài)上的反映”。3、代表人物：普羅泰格拉4、研究領(lǐng)域：人和人類社會(huì)關(guān)注人與人之間的關(guān)系、社會(huì)組織、風(fēng)俗習(xí)慣和倫理規(guī)范
人教版新課標(biāo)高中物理必修1伽利略對(duì)自由落體運(yùn)動(dòng)的研究教案2篇
猜想：既然物體下落過程中的運(yùn)動(dòng)情況與物體質(zhì)量無(wú)關(guān)，那么為什么在現(xiàn)實(shí)生活中，不同物體的落體運(yùn)動(dòng)，下落快慢不同呢？我們能否猜想是由于空氣阻力的作用造成的呢？如果沒有空氣阻力將會(huì)怎樣呢？學(xué)生討論后回答.三、猜想與假說伽利略認(rèn)為，自由落體是一種最簡(jiǎn)單的變速運(yùn)動(dòng).他設(shè)想，最簡(jiǎn)單的變速運(yùn)動(dòng)的速度應(yīng)該是均勻變化的.但是，速度的變化怎樣才算均勻呢?他考慮了兩種可能：一種是速度的變化對(duì)時(shí)間來(lái)說是均勻的，即經(jīng)過相等的時(shí)間，速度的變化相等；另一種是速度的變化對(duì)位移來(lái)說是均勻的，即經(jīng)過相等的位移，速度的變化相等.伽利略假設(shè)第一種方式最簡(jiǎn)單，并把這種運(yùn)動(dòng)叫做勻變速運(yùn)動(dòng).四、實(shí)驗(yàn)驗(yàn)證實(shí)驗(yàn)驗(yàn)證是檢驗(yàn)理論正確與否的唯一標(biāo)準(zhǔn).任何結(jié)論和猜想都必須經(jīng)過實(shí)驗(yàn)驗(yàn)證，否則不成理論.猜想或假說只有通過驗(yàn)證才會(huì)成為理論.所謂實(shí)驗(yàn)驗(yàn)證就是任何人，在理論條件下去操作都能到得實(shí)驗(yàn)結(jié)果，它具有任意性，但不是無(wú)條件的，實(shí)驗(yàn)是在一定條件下的驗(yàn)證，而與實(shí)際有區(qū)別.

②其他貨幣與美元掛鉤：即各會(huì)員國(guó)貨幣對(duì)美元的匯率按各自貨幣的含金量與美元確定固定比價(jià)。各國(guó)貨幣與美元的匯率可按各國(guó)貨幣含金量與美元含金量之比來(lái)確定，這稱為法定匯率。例如，1946年一英鎊的含金量為3．58134克，一美元的含金量為0．888671克，則英鎊和美元的含金量之比1英鎊＝4．03美元就是法定匯率。這一規(guī)定，使美元等同于黃金，美元從此有了“美金”的說法；與美元比起來(lái)，其他國(guó)家的貨幣處于從屬地位，確立了美元在國(guó)際貨幣體系中的中心地位、主導(dǎo)地位正如當(dāng)時(shí)美國(guó)財(cái)政部長(zhǎng)福勒所說：“各個(gè)行星圍繞著太陽(yáng)轉(zhuǎn)，各國(guó)貨幣圍繞著美元轉(zhuǎn)?！毙〗Y(jié)： “布雷頓森林體系”是一個(gè)以美元為中心的世界貨幣體系，美國(guó)通過布雷頓森林體系，掌握了資本主義世界的經(jīng)濟(jì)命脈。（2）影響：①為世界貨幣關(guān)系提供了統(tǒng)一的標(biāo)準(zhǔn)和基礎(chǔ)，有利于維持戰(zhàn)后世界貨幣體系的正常運(yùn)轉(zhuǎn)，為世界經(jīng)濟(jì)的恢復(fù)和發(fā)展創(chuàng)造了條件。

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)算說明（2）若能跨過，求落地速度？
