Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

蘇格拉底把裝有毒酒的杯子舉到胸口，平靜地說：“分手的時候到了，我將死，你們活下來，是誰的選擇好，只有天知道?！闭f畢，一口喝干了毒酒。（2） 蘇格拉底臨死前對一個叫克力同的人說了這樣一番話?？肆ν腋嬖V你，這幾天一直有一個神的聲音在我心中曉喻我，他說：“蘇格拉底，還是聽我們的建議吧，我們是你的衛(wèi)士。不要考慮你的子女、生命或其他東西勝過考慮什么是公正?！聦嵣夏憔鸵x開這里了。當你去死的時候，你是個犧牲品，但不是我們所犯錯誤的犧牲品，而是你同胞所犯錯誤的犧牲品。但你若用這種可恥的方法逃避，以錯還錯，以惡報惡，踐踏你自己和我們訂立的協(xié)議合約，那么你傷害了你最不應該傷害的，包括你自己、你的朋友、你的國家，還有我們。到那時，你活著面對我們的憤怒，你死后我們的兄弟、冥府里的法律也不會熱情歡迎你；因為它們知道你試圖盡力摧毀我們。別接受克力同的建議，聽我們的勸告吧?！?/p>
人教版高中政治必修3在文化生活中選擇說課稿
一、教材分析文化市場和大眾傳媒的發(fā)展，給我們的文化生活帶來了許多可喜的變化。但是，文化市場的自發(fā)性和傳媒的商業(yè)性也引發(fā)了令人憂慮的現(xiàn)象。文化生活有“喜”也有“憂”，讓我們歡喜讓我們憂。面對形式多樣的文化生活，置身于文化生活的海洋之中，在文化生活中如何選擇、怎樣作出正確的選擇是亟待向學生解決的問題。二、學情分析高二學生處于世界觀、人生觀和價值觀形成的關鍵時期，身心迅速發(fā)展，自我意識和獨立性較強，社會公共生活空間范圍越來越大，并且開始理性地思考社會和人生的重大問題，他們可塑性強，但情緒仍然不穩(wěn)定，有多變性，容易沖動或偏激，迫切需要提升思想意識，加強方法論的指導，使其在紛繁復雜的文化生活中能夠進行正確的判斷與選擇。如果我們的學生不能把握正確的航向，是非觀念模糊，良莠不分，就會陷入落后文化和腐朽文化的泥沼而不能自拔，甚至造成無法挽回的惡果。

人教版高中歷史必修1新中國的民主政治建設說課稿2篇
（一）教材的地位新中國的成立是20世紀的一件大事。它結束了幾千年封建專制統(tǒng)治的歷史，開啟了中華民族發(fā)展的新紀元。本課側重這一時期一個非常顯著的特征，即制度的更新，它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進了社會經(jīng)濟的發(fā)展，也為祖國的統(tǒng)一奠定了重要基礎。（二）教學目標依據(jù)新課程以人為本，促進學生全面發(fā)展的要求，同時,針對高一年級學生具備一定基礎知識但掌握不牢固，對歷史興趣濃厚但又自制能力差的特點，我對本課的三維目標設定如下：見多媒體。（三）教學重點的確定及處理本課的主題是新中國的民主政治建設，這個問題的掌握對以后學習中國民主政治建設的進程有很大幫助，并且學生能力的提高也有賴于對它的認識，所以確定“人民代表大會制度的創(chuàng)立”是教學重點。
人教版高中歷史必修1秦朝中央集權制度的形成說課稿2篇
問題設計：通過這一課的學習，同學們能解釋君主專制中央集權制度的含義嗎？【總結】封建專制主義中央集權制度包括專制主義和中央集權制兩個概念。專制主義是就中央的決策方式而言的，主要體現(xiàn)在皇位終身制和世襲制上，特征是皇帝個人獨裁專斷，集國家最高權力于一身，從決策到行使軍政財權都具有獨斷性和隨意性；中央集權則是相對于地方分權而言，其特點是地方政府在政治、經(jīng)濟、軍事等方面沒有獨立性，必須充分執(zhí)行中央的政令，一切服從于中央。三、秦朝中央集權制的影響展示圖片：《秦朝疆域圖》正是由于有一個統(tǒng)一集中的中央政權，秦王朝才能積極開拓疆域，北拒匈奴，南吞百越，有利于我國多民族國家統(tǒng)一發(fā)展。為了鞏固統(tǒng)一的國家，秦朝還通過實行哪些措施鞏固統(tǒng)一局面？展示圖片：“秦半兩錢”“秦權”“小篆”“秦簡”等圖片。正是有一個強有力中央政府，才統(tǒng)一了貨幣、文字、度量衡，才開驛道、修靈渠，從而促進了中國經(jīng)濟文化的發(fā)展進步。展示“孟姜女哭長城”的故事材料從故事及你所掌握的材料中，你認為秦朝能否長治久安？為什么？
人教版高中政治必修3建設社會主義精神文明說課稿
最后，教師對這節(jié)課學習的內容做回顧總結，并讓學生做幾道練習題鞏固一下新知識。依據(jù)：本節(jié)課主要是通過學生對關中文化的了解來學習我國的傳統(tǒng)文化。所以我計劃通過3-5分鐘的設問導課讓學生把注意力轉變集中到課堂中，引導學生關注課堂。整體時間安排符合教育學中的最佳時間分配原理和反饋原理。這樣做也有利于優(yōu)化課堂結構、提高教學效率、把主要時間留給學生，把主動權還給學生。針對高三年級學生的層次差異，我進行了分層設置，設置有基礎題和拔高題。這樣做既可以使學生掌握基礎知識，又可以使學有余力的學生有所提高，從而達到拔尖和“減負”的目的。板書設計板書就是微型教案，板書集中體現(xiàn)教學的三維目標、重難點、教學過程，體現(xiàn)教學的特色與特性。

人教版高中政治必修3世界文化的多樣性說課稿
1、 說教材的地位和作用《世界文化的多樣性》是人教版必修教材《文化生活》第二單元第一課的第一個框題。多樣性是當代世界文化的重要特征，也是文化交流和傳播的前提。因此，本框知識具有承前啟后的作用，在本單元中，它是一個引子，開啟了本單元知識的學習之門。2、 說教學的重、難點根據(jù)課程標準以及高二學生的知識結構和思維特點，我確定了教學重點和難點。教學重點：民族文化的多樣性。確定重點的依據(jù)：豐富的世界文化表現(xiàn)在文字、建筑、服飾、飲食、宗教信仰、思想理論、文學藝術、風俗習慣等眾多方面。世界有許多輝煌的文化成就和著稱于世的文化遺產(chǎn)。可以說，世界文化的多樣性主要表現(xiàn)在民族文化的多樣性。在教材內容中有許多關于文化的論述和概念。其中“民族文化的多樣性”起著關鍵性的作用。難點：尊重文化多樣性必然性。
人教版高中歷史必修3新文化運動與馬克思主義的傳播說課稿
一、說教材（一）教材分析本課所介紹的新文化運動，是繼上一節(jié)所學的《西學東漸和維新變法思想》之后中國另一波影響巨大的思想解放潮流，旨在向西方學習、尋求強國御侮之道。在整個知識體系中，它既是資產(chǎn)階級領導的舊民主主義革命的補課，又是無產(chǎn)階級領導的新民主主義革命的序曲。它所帶來的思想的空前解放，也就為馬克思主義的傳播創(chuàng)造了條件，為中共的成立奠定基礎。這一課的學習能讓學生清晰認識新文化運動和馬克思主義在近代中國思想解放歷程中的重要作用和巨大影響。與必修一和必修二政治經(jīng)濟史的結合也能讓使學生強化歷史聯(lián)系。新課程標準對本課就做了明確的規(guī)定：1、概述新文化運動的主要內容，探討其對近代中國思想解放的影響。2、簡述馬克思主義在中國傳播的史實，認識馬克思主義對中國歷史發(fā)展的重大意義。根據(jù)課標要求，我制定了以下具體的三維目標。

人教版高中政治必修3世界文化的多樣性說課稿
設計意圖：使同學從各屆奧運會會徽的設計上看各國文化，讓學生體會不同會徽體現(xiàn)的不同的民族文化，了解不同民族的文化特色，感悟文化多樣性的價值，使學生產(chǎn)生情感認同，從而突破難點。探究活動5：教師多媒體呈現(xiàn)中法文化年的flash，顯示中國到法國舉辦中國文化年的圖片，比如：在法國街頭出現(xiàn)了中國的京劇臉譜，中國孩子玩的風車，中國的大熊貓。出示法國到中國舉辦文化年的圖片，比如：法國在北京舉辦的音樂會，法國空軍的飛行表演等。學生討論：中法文化年的舉辦對中法兩國來說有什么現(xiàn)實意義？探究活動6：播放理查德.克萊德曼演奏的《梁山伯與祝英臺》的視頻討論：（1）此曲吸引你之處在哪里？（2）由此可見，對待文化差異的正確態(tài)度是什么？活動5和活動6的設計意圖在于讓學生懂得，面對開放的世界，既要尊重本民族的文化，同時也要尊重其他民族的文化，從而突破難點。
人教版高中政治必修3文化創(chuàng)新的源泉和作用說課稿
二、巨大的作用，深刻地意義材料展示：魯迅在《狂人日記》中猛烈抨擊“吃人”的封建禮教，力圖通過自己的吶喊喚醒民眾。高爾基早期的作品多描繪俄國沙皇制度下人民的痛苦和他們對美好生活的憧憬。20世紀初，俄國革命形勢的發(fā)展使他講文學的筆鋒轉向革命，創(chuàng)作了《母親》等作品。合作探究：魯迅和高爾基的作品在當時的中國和俄國分別起到了什么作用？列舉喜愛的一些文學和藝術作品，說說創(chuàng)作者的意圖是什么？引導學生自主閱讀，培養(yǎng)自主學習能力，掌握分析歸納法和團結協(xié)作精神。學生回答之后師生共同總結：文化創(chuàng)新來源于社會實踐，同也會對于社會實踐產(chǎn)生新的影響，促進社會實踐的變化，同時也繁榮了民族文化。所以文化創(chuàng)新的巨大作用一方面表現(xiàn)為推動社會實踐的發(fā)展，另一方面表現(xiàn)為不斷促進民族文化的繁榮。既然文化創(chuàng)新具有如此巨大的作用，那么作為新時代祖國的建設者為了繁榮民族文化，又該作些什么呢？進入本課第三目和教學的第三個環(huán)節(jié)。[情景回歸參與生活]
