8、文化傳播的含義：文化交流的過程，就是文化傳播的過程。 人們通過一定的方式傳遞知識、信息、觀念、情感和信仰，以及與此相關(guān)的所有社會交往活動，都可視為文化傳播。9、文化傳播的途徑(1)商業(yè)活動。商人進(jìn)行貿(mào)易活動時(shí)，不僅通過商品交換將商品中蘊(yùn)涵的豐富文化加以交流，而且通過人與人之間的交往過程交流文化。(2)人口遷徙。每一次大規(guī)模的人口遷徙，都意味著大規(guī)模的文化傳播，都會對當(dāng)時(shí)當(dāng)?shù)氐慕?jīng)濟(jì)、政治、文化產(chǎn)生極大的影響。(3)教育教育是文化傳播的又一重要途徑。人們通過學(xué)習(xí)各種文化課程，能夠獲得不同的文化知識。文化傳播是教育的重要功能。10、大眾傳媒：現(xiàn)代文化傳播的手段現(xiàn)代社會中的傳媒有報(bào)刊、廣播、電視、網(wǎng)絡(luò)等多種形式，這類傳媒被稱為大眾傳媒。依托現(xiàn)代信息技術(shù)，大眾傳媒能夠最大程度地超越時(shí)空的局限，匯集來自世界各地的信息，日益顯示出文化傳遞、溝通、共享的強(qiáng)大功能，已成為文化傳播的主要手段。
人教版高中地理必修1自然地理環(huán)境的整體性教案
1．生產(chǎn)功能：合成有機(jī)物的能力2．平衡功能：使自然地理要素的性質(zhì)保持穩(wěn)定的能力【教師講解】生產(chǎn)功能主要依賴于光合作用。在光合作用過程中，植物提供葉綠素，大氣提供熱量和二氧化碳，土壤及水圈、巖石圈提供水分及無機(jī)鹽。光合作用通過物質(zhì)和能量的交換，將生物、大氣、水、土壤、巖石等地理要素統(tǒng)一在一起，在一定的條件下，生產(chǎn)出有機(jī)物。由此可見，生產(chǎn)功能是自然環(huán)境的整體功能而非單個(gè)地理要素的功能。大氣本身不具有減緩二氧化碳增加的功能，但是，在自然地理環(huán)境中，通過各地理要素的相互作用，卻能消除部分新增的二氧化碳的能力，既為自然地理環(huán)境的平衡功能。請大家閱讀教材P94活動，利用平衡功能的原理，解釋一定范圍內(nèi)各物種的數(shù)量基本恒定這一現(xiàn)象?！緦W(xué)生討論回答】略。（可參考教參）【轉(zhuǎn)折】自然地理環(huán)境各要素每時(shí)每刻都在演化，如我們熟知的氣候變化、地貌變化等。各個(gè)要素的發(fā)展演化是統(tǒng)一的，一個(gè)要素的演化伴隨著其他各個(gè)要素的演化。

7．讓學(xué)生閱讀基因控制蛋白質(zhì)合成的過程（轉(zhuǎn)錄,翻譯）13分鐘 動畫演示“轉(zhuǎn)錄,翻譯”過程兩次,讓學(xué)生有個(gè)整體印象。 培養(yǎng)學(xué)生自學(xué)習(xí)慣，突出教學(xué)過程中的學(xué)生為主體的教學(xué)思想。 8．配合動畫引導(dǎo)學(xué)生根據(jù)預(yù)習(xí)逐段講解。 注意問題（1）轉(zhuǎn)錄,翻譯的地點(diǎn),模板,生成物不同。因?yàn)檫@是一個(gè)極其復(fù)雜的過程,避免學(xué)生在學(xué)習(xí)過程中相混肴.（2）這個(gè)問題的闡明能為后面“密碼子”的概念做好鋪墊,避免學(xué)生搞不清“遺傳密碼”和“遺傳信息”兩個(gè)概念。 9．打出板書。 通過動畫演示,加深學(xué)生的理解和掌握,提高學(xué)習(xí)效率。 10．重播全過程動畫,引導(dǎo)學(xué)生講述。7分鐘 _x0007_加深認(rèn)識,完成從量變到質(zhì)變的飛躍。 11．過渡：就這樣，以DNA為模板合成信使RNA，再以信使RNA為模板,以轉(zhuǎn)運(yùn)RNA為運(yùn)載工具,使氨基酸在核糖體中按照一定的順序排列起來,合成了與親代一樣的蛋白質(zhì),從而顯現(xiàn)出與親代同樣的性狀。從而引出“中心法則”。

設(shè)計(jì)意圖：使同學(xué)從各屆奧運(yùn)會會徽的設(shè)計(jì)上看各國文化，讓學(xué)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(jià)值，使學(xué)生產(chǎn)生情感認(rèn)同，從而突破難點(diǎn)。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(fēng)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(xué)生討論：中法文化年的舉辦對中法兩國來說有什么現(xiàn)實(shí)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(shè)計(jì)意圖在于讓學(xué)生懂得，面對開放的世界，既要尊重本民族的文化，同時(shí)也要尊重其他民族的文化，從而突破難點(diǎn)。
