（三月二十六日）國旗下講話：安全教育日
我是來自高二六班的xx，非常榮幸能在國旗下代表上周值周班高二六班演講。今天我演講的主題是：安全——教育的保障。大家知道嗎，三月二十六日是“全國中小學(xué)生安全宣傳教育日”。 據(jù)權(quán)威數(shù)據(jù)顯示，我國現(xiàn)有18歲以下未成年人億人，平均每年意外傷害人數(shù)約為4000萬人次，醫(yī)療費(fèi)用億元，平均每年約有萬名中小學(xué)生非正常傷亡。為推動(dòng)中小學(xué)安全教育工作，降低青少年傷亡事故的發(fā)生率，保證青少年健康成長。1996年由國家教育部、公安部等七部委聯(lián)合發(fā)文，確定每年三月份最后一周的星期一作為全國中小學(xué)生“安全教育日”，每年確定一個(gè)主題。 如果說學(xué)生是祖國的花朵，安全就恰如花朵下的土壤，是花朵生長的保障。我的班主任常常教導(dǎo)我說：“一定要注意安全，父母把自己養(yǎng)這么大不容易。”直到我把腳歪到之前，我還不曾意識(shí)到安全的重要性。

國旗下的講話：銘記一二·九（學(xué)生演講稿）
國旗下的講話：銘記一二·九 各位老師、同學(xué)們：早上好！今天是一二。九運(yùn)動(dòng)的紀(jì)念日，這個(gè)青年學(xué)生的愛國運(yùn)動(dòng)距今已有73周年了。今天，站在鮮艷的國旗下，讓我們一同回顧歷史：誰都應(yīng)該記得1935年的12月9日，誰都不應(yīng)該忘記“一二。九”這場轟轟烈烈的學(xué)生愛國救亡運(yùn)動(dòng)。雖然，它早已成為歷史，但它的事跡，它的精神，卻早已銘刻進(jìn)了我們每一位炎黃子孫的心中。他們用自己的青春和熱血掀起了全國抗日救亡運(yùn)動(dòng)新的高潮。今天，我們在這里緬懷一二。九先輩的功績，心潮澎湃，不能自己。作為新時(shí)代的青少年，同學(xué)們，我們又應(yīng)該做些什么？抗戰(zhàn)時(shí)期的大中學(xué)學(xué)生，他們把自己的生命和國家的命運(yùn)、民族的興亡，緊緊的聯(lián)系在了一起。而我們，是否也應(yīng)該象他們一樣呢？答案當(dāng)然是肯定的，但現(xiàn)實(shí)又如何呢？臺(tái)下的有一部分同學(xué)，當(dāng)你在課堂上無精打采的聽課時(shí)，當(dāng)你將青春耗費(fèi)在虛擬的網(wǎng)絡(luò)時(shí)空時(shí)，當(dāng)你沉溺于追逐流行和崇拜明星時(shí)，當(dāng)你盲目的“?？帷薄把b帥”，張揚(yáng)你所謂的“個(gè)性”時(shí)，不知你是否想到了作為當(dāng)代青少年那肩頭沉重的使命感？
高二學(xué)生國旗下講話稿：天下興亡，我的責(zé)任
敬愛的老師們，親愛的同學(xué)們：大家早上好！我先給大家講一個(gè)故事：1920年，有一位11歲的美國男孩在踢足球時(shí)不小心踢碎了鄰居家的玻璃，鄰居憤怒不已，向他索賠12.5美元。這12.5美元在當(dāng)時(shí)可謂是天文數(shù)字，足夠買下125只生蛋的母雞了。男孩把闖禍的事情告訴父親，并且懺悔。見兒子為難的樣子，父親拿出了12.5美元說：“這筆錢是我借給你的，一年后你要分毫不差地還給我?！睆拇耍@個(gè)男孩每逢周末、假日，便外出辛勤打工。經(jīng)過半年的努力，他終于掙足了12.5美元，分毫不差地還給了父親。這個(gè)男孩就是后來的美國總統(tǒng)里根。他在回憶這件事時(shí)說：“通過自己的勞動(dòng)來承擔(dān)過失，使我懂得了什么叫責(zé)任?！必?zé)任，這兩個(gè)字很好讀，一點(diǎn)也不拗口，但這是個(gè)沉甸甸的話題。責(zé)任是什么？用歌德的話來講，就是對自己要求去做的事情有一種愛。這是一個(gè)真實(shí)的故事。有一個(gè)人來他公司應(yīng)聘，經(jīng)過交談，他覺得那個(gè)人不適合他們公司的工作。因此，他很客氣地和那個(gè)人道別。那個(gè)人從椅子上站起來時(shí)，手指不小心被椅子跳出來的釘子劃了一下。那人順手拿起老板桌子上的鎮(zhèn)紙，把跳出來的釘子砸了進(jìn)去，然后和老板再見。
初二學(xué)生國旗下講話稿——我心中的木棉花
在我們附中的東南角，有一棵高大的木棉樹。木棉，是我們廣州市的市花，是花園酒店、中國南方航空公司和廣州電視臺(tái)使用的標(biāo)志，也是XX年第一屆亞洲殘疾人運(yùn)動(dòng)會(huì)的吉祥物。每年四月，當(dāng)北方才剛剛有綠色的影子的時(shí)候，火紅的木棉已經(jīng)燦爛耀眼，它火紅火紅，一朵一朵像綻放的笑臉，像一片一片熊熊的火焰燃燒在枝頭，它象征和平、幸福、友誼、安康。（它的花語告訴我們----珍惜身邊的人，珍惜眼前的幸福?。┛墒亲罱?，由于木棉花的花期短、覆蓋率少，民間發(fā)出是否可以評選“第二市花”的建議，這也使我再次關(guān)注我們廣州的“英雄花”——木棉。記得小時(shí)候，在珠江沿岸，每年燕子唱歌的時(shí)候，濱江路的木棉花總是開得最旺盛。吃過晚飯下樓散步，總能撿到一、二十朵掉落的木棉；有時(shí)在樹下跑過，總能聽見那木棉落在地上的聲音。每每撿到木棉花，我總是把它們揣在衣服里，到了家，母親就把較好的收集起來，夏天熬粥。我，就是吃著那又澀又甜的木棉花粥長大的。作為一個(gè)土生土長的廣州仔，木棉花，就像是我的朋友。
初二學(xué)生國旗下講話稿：構(gòu)建和諧校園
我是初二7班xxx，今天我講話的主題是“構(gòu)建和諧校園”。和諧是事物存在的最佳狀態(tài)，也是一切美好事物的共同特點(diǎn)。實(shí)現(xiàn)和諧，是古往今來人類孜孜以求的美好理想和愿望。而調(diào)動(dòng)一切積極因素構(gòu)建和諧文明的校園環(huán)境也將是一個(gè)永恒的主題。構(gòu)建和諧校園需建立和諧的師生關(guān)系。師者，傳道授業(yè)解惑也，是老師給了我們文化知識(shí)的啟迪，使我們從無知到有知，從幼稚走向成熟。老師給了我們知識(shí)的雨露，我們要全身心的接受，珍惜老師的付出，尊重老師的勞動(dòng)。師生互敬互愛，從而打造和諧的學(xué)習(xí)氛圍。構(gòu)建和諧校園需建立建立和諧的同學(xué)關(guān)系。關(guān)心幫助有困難的同學(xué)，讓他們感受到和諧校園的溫馨。

生2：頷聯(lián)的意思是只聽到禁衛(wèi)軍中傳來夜間巡邏的梆子聲，不再向?qū)m中那樣安逸地聽到有雞人打鳴報(bào)時(shí)的聲音了。生3：頸聯(lián)的意思是說事變發(fā)生那天軍隊(duì)發(fā)生嘩變停留不前，但當(dāng)年唐玄宗以為自己可以和貴妃天天在一起，對天上的牽牛和織女一年一度的會(huì)見還加以嘲笑呢。生4：尾聯(lián)的含義是為什么唐玄宗當(dāng)了四十五年的皇帝，還不如普通百姓夫妻恩愛，長相廝守。師：好的。請大家再齊讀一遍詩文，做到人人都能疏通詩的含義。學(xué)生再次齊讀。第三環(huán)節(jié)：專項(xiàng)探究師：白居易曾說：“文章合為時(shí)而著，歌詩合為事而作?！边@首詩就是作者途經(jīng)馬嵬驛，詠馬嵬之變這一歷史事件而作，所以我們鑒賞的第三步，就是通過標(biāo)題和詩文，弄清詩中的歷史事件。請同學(xué)們找出詩中哪些詩句描述了這一事件？

二、學(xué)生情況分析(說學(xué)法)1、學(xué)生學(xué)習(xí)基礎(chǔ)分析：學(xué)生通過對《生活與哲學(xué)》前面三個(gè)單元的學(xué)習(xí)，初步掌握了運(yùn)用唯物論、辯證法、認(rèn)識(shí)論的觀點(diǎn)去認(rèn)識(shí)問題、分析問題的能力；再通過對第十一課的學(xué)習(xí)，學(xué)生對馬克思主義的歷史觀有了初步的理解，初步樹立了正確的理想信念，這為本課教學(xué)目標(biāo)的落實(shí)奠定了知識(shí)基礎(chǔ)。 2、學(xué)生能力分析 ：高二學(xué)生擁有一定生活體驗(yàn)，具備一定的信息收集和篩選能力、閱讀能力、語言表達(dá)能力、對問題的一定的探究能力，同伴合作能力和具備初步邏輯思維能力。3、學(xué)生心理分析：在我國現(xiàn)階段，以為人民服務(wù)為核心的社會(huì)主義道德建設(shè)過程中涌現(xiàn)了大批的先進(jìn)人物和道德典范，但同時(shí)由于社會(huì)價(jià)值的多元化，個(gè)人主義、享樂主義、拜金主義等資本主義腐朽思想也同樣在影響著當(dāng)代的中學(xué)生。
