人教版高中语文必修3《马嵬（其二）》教案2篇
结合历史自古以来，江山美人历来都是引无数英雄豪杰竞折腰的，如果说英雄选择了美人却丢了江山，把所有罪名都归结于“女人是祸水”。但是，纣王无道，和有了妲己有必然的联系吗？有人说妲己坏透了，坏透了的妲己如果不是取得纣王的信任是坏不起来的，纣王听信了妲己的谗言，听与不听决定权在纣王，而不在妲己。强势永远在纣王一边。再来看看西施和杨贵妃：西施是作为越国贡献给吴国的供品来到吴王夫差的身边的，杨贵妃更是先是李隆基的儿媳妇被看中而得宠的。所以，西施和杨贵妃这两个可怜的女人根本没有自己的独立选择，没有独立的爱情，如果没有西施，就会有南施，或北施；如果没有杨贵妃，就会有李贵妃，王贵妃，总之什么施，什么妃是不能少的，因为那是吴王和李隆基的需要。

高二学生国旗下讲话稿：天下兴亡，我的责任
敬爱的老师们，亲爱的同学们：大家早上好！我先给大家讲一个故事：1920年，有一位11岁的美国男孩在踢足球时不小心踢碎了邻居家的玻璃，邻居愤怒不已，向他索赔12.5美元。这12.5美元在当时可谓是天文数字，足够买下125只生蛋的母鸡了。男孩把闯祸的事情告诉父亲，并且忏悔。见儿子为难的样子，父亲拿出了12.5美元说：“这笔钱是我借给你的，一年后你要分毫不差地还给我。”从此，这个男孩每逢周末、假日，便外出辛勤打工。经过半年的努力，他终于挣足了12.5美元，分毫不差地还给了父亲。这个男孩就是后来的美国总统里根。他在回忆这件事时说：“通过自己的劳动来承担过失，使我懂得了什么叫责任。”责任，这两个字很好读，一点也不拗口，但这是个沉甸甸的话题。责任是什么？用歌德的话来讲，就是对自己要求去做的事情有一种爱。这是一个真实的故事。有一个人来他公司应聘，经过交谈，他觉得那个人不适合他们公司的工作。因此，他很客气地和那个人道别。那个人从椅子上站起来时，手指不小心被椅子跳出来的钉子划了一下。那人顺手拿起老板桌子上的镇纸，把跳出来的钉子砸了进去，然后和老板再见。
第十二周国旗下讲话稿：做文明学生，创和谐校园
尊敬的各位老师、亲爱的同学们：今天我演讲的题目是：做文明学生，创和谐校园。文明是文明是一种习惯，他体现着人们的生活态度；文明是一种精神，他体现着人们的风貌；文明是一种素质，告别昨日的无知和粗俗……在我们身边，在一部分同学身上，还存在着一些不文明的行为。例如，在我们的校园内总能见到与我们美丽的校园极不和谐的纸屑和食品包装袋，甚至有的同学认为：反正有值日的同学做清洁工作打扫，扔了又何妨；再例如有的同学在教学楼走廊上追逐打闹，走路推推搡搡习以为常；还有部分同学相互之间讲脏话、粗话。
初二学生国旗下讲话稿——我心中的木棉花
在我们附中的东南角，有一棵高大的木棉树。木棉，是我们广州市的市花，是花园酒店、中国南方航空公司和广州电视台使用的标志，也是XX年第一届亚洲残疾人运动会的吉祥物。每年四月，当北方才刚刚有绿色的影子的时候，火红的木棉已经灿烂耀眼，它火红火红，一朵一朵像绽放的笑脸，像一片一片熊熊的火焰燃烧在枝头，它象征和平、幸福、友谊、安康。（它的花语告诉我们----珍惜身边的人，珍惜眼前的幸福！）可是最近，由于木棉花的花期短、覆盖率少，民间发出是否可以评选“第二市花”的建议，这也使我再次关注我们广州的“英雄花”——木棉。记得小时候，在珠江沿岸，每年燕子唱歌的时候，滨江路的木棉花总是开得最旺盛。吃过晚饭下楼散步，总能捡到一、二十朵掉落的木棉；有时在树下跑过，总能听见那木棉落在地上的声音。每每捡到木棉花，我总是把它们揣在衣服里，到了家，母亲就把较好的收集起来，夏天熬粥。我，就是吃着那又涩又甜的木棉花粥长大的。作为一个土生土长的广州仔，木棉花，就像是我的朋友。
XX—XX第二学期第五周国旗下讲话稿：预防近视
尊敬的老师，亲爱的同学们：大家好!今天，国旗下讲话的主题是《爱自己，从爱护眼睛开始》。我们都知道眼睛是心灵的窗户，爱自己，就一定要爱护好眼睛。特别是我们小学生处于人生学习的黄金期，天天学习离不开眼睛。据有关资料显示，我国有五百万盲人，七百万双眼低视力者，单眼低视力者高达四千万人。同学们你们知道吗?一旦患了近视，戴上眼镜会给学习和生活带来很多不便。例如在参加体育活动的时候，打篮球或踢足球时，打破眼镜甚至伤及眼睛到医院做手术缝合是常有的事。形形色色的眼病不仅严重危害了人们的身心健康，也阻碍了人们生活质量的提高。一个正常人如果离开了眼睛简直无法想象怎样生活?看看我们周围，真正明亮的眼睛又有多少呢?眼睛可以让我们去认识世界，学习知识，如果我们失去了明亮的眼睛，我们的世界将是黑暗的。同学们在日常生活和学习中一定要自觉的注意科学用眼。
国旗下的讲话：铭记一二·九（学生演讲稿）
国旗下的讲话：铭记一二·九 各位老师、同学们：早上好！今天是一二。九运动的纪念日，这个青年学生的爱国运动距今已有73周年了。今天，站在鲜艳的国旗下，让我们一同回顾历史：谁都应该记得1935年的12月9日，谁都不应该忘记“一二。九”这场轰轰烈烈的学生爱国救亡运动。虽然，它早已成为历史，但它的事迹，它的精神，却早已铭刻进了我们每一位炎黄子孙的心中。他们用自己的青春和热血掀起了全国抗日救亡运动新的高潮。今天，我们在这里缅怀一二。九先辈的功绩，心潮澎湃，不能自己。作为新时代的青少年，同学们，我们又应该做些什么？抗战时期的大中学学生，他们把自己的生命和国家的命运、民族的兴亡，紧紧的联系在了一起。而我们，是否也应该象他们一样呢？答案当然是肯定的，但现实又如何呢？台下的有一部分同学，当你在课堂上无精打采的听课时，当你将青春耗费在虚拟的网络时空时，当你沉溺于追逐流行和崇拜明星时，当你盲目的“耍酷”“装帅”，张扬你所谓的“个性”时，不知你是否想到了作为当代青少年那肩头沉重的使命感？
第二周国旗下讲话稿：励志勤学，走向成功
敬爱的老师们，亲爱的同学们：早上好！我是高一8班的申佳颐，今天我国旗下讲话的题目是：励志勤学，走向成功。励志，首先要有志向，有高尚、远大的理想和明确的奋斗目标。少年周恩来曾在全班同学面前表明了自己的心迹：要“为中华之崛起而读书”。他把个人的学习与民族振兴的大业联系起来，立下远大志向，为祖国的兴盛而学习和奋斗，后来成为新中国的第一任总理，受到全国人民乃至世界各国人民的爱戴。再者，26岁的毛泽东发出“怅寥廓，问苍茫大地，谁主沉浮？”的感慨，并将改造中国的责任毅然担当起来，创造了如今的中华人民共和国。可见，高尚、远大的理想和明确的奋斗目标对人一生的引领作用有多么巨大！其次，励志一定要有实践，要为实现志向而进行不懈的努力。爱因斯坦说过，“任何一件你喜欢的事，只要每天干一个小时，每天干，连续干上五年后，你就可以成为最专业的人才。”当你定下自己的奋斗目标后，就要坚定不移的干下去。泰戈尔有这样一句至理名言:“只有流过血的手指，才能弹出世间的绝唱，只有经历过地狱般的磨练，才能练出创造天堂的力量。”学习理应如此。
初二学生国旗下讲话稿：构建和谐校园
我是初二7班xxx，今天我讲话的主题是“构建和谐校园”。和谐是事物存在的最佳状态，也是一切美好事物的共同特点。实现和谐，是古往今来人类孜孜以求的美好理想和愿望。而调动一切积极因素构建和谐文明的校园环境也将是一个永恒的主题。构建和谐校园需建立和谐的师生关系。师者，传道授业解惑也，是老师给了我们文化知识的启迪，使我们从无知到有知，从幼稚走向成熟。老师给了我们知识的雨露，我们要全身心的接受，珍惜老师的付出，尊重老师的劳动。师生互敬互爱，从而打造和谐的学习氛围。构建和谐校园需建立建立和谐的同学关系。关心帮助有困难的同学，让他们感受到和谐校园的温馨。
XX年春季期第二学期3月份国旗下讲话
主题 学习雷锋好榜样尊敬的老师、亲爱的同学们，大家好！963年3月5日，毛泽东同志发出了“向雷锋同志学习”的号召。40多年来，雷锋成为我们社会真情与爱心的化身，成为中国人民可贵的精神财富；雷锋精神刻在人们的灵魂深处，引领着一代又一代人健康成长。同学们，雷锋这个名字你一定不会陌生，但你可知道，什么是雷锋精神？第一，奉献社会。一个人做一件好事并不难，难的是一辈子做好事。雷锋坚持一辈子做好事，一辈子为人民服务，在他身上体现的是一种强烈的社会责任感。一次雷锋外出，在沈阳站换车的时候，发现一个背着小孩的中年妇女车票和钱丢了，就买了一张火车票塞到大嫂手里。大嫂含着眼泪问：“大兄弟，你叫什么名字，是哪个单位的？”雷锋说：“我叫解放军，就住在中国。”“雷锋出差一千里，好事做了一火车”。弘扬雷锋精神，就是要像雷锋那样，把社会责任感和使命感记在心间，随时随地为祖国和人民贡献自己的智慧和力量。第二，刻苦学习。雷锋不仅是奉献的楷模，还是学习成才的典范。他干一行爱一行，干一行专一行，挤出一切可以挤出的时间，努力学习为人民服务的本领。雷锋参军后不久，被分到运输连当汽车兵,他就把书本装在挎包里,只要车一停,他就坐在驾驶室里看书。他在日记中写道:“要学习，时间总是有的,问题是我们善不善于挤,愿不愿意钻。一块好好的木板,上面一个眼也没有,但钉子为什么能钻进去呢?我们在学习上也要提倡这种钉子精神,善于挤和钻。”
