关于10月1日国庆节国旗下的讲话
敬爱的老师，亲爱的同学们：大家好！再过两天就是一年一度的国庆节了，一直以来，国庆节在我的印象中就是放长假的代名词，每逢国庆，我就可以和爸爸妈妈一起出去旅游，去游山玩水，一家人沉侵在欢乐的气氛中。妈妈对我说：“你这么幸福，是你生活在我们伟大的祖国，生活在幸福的年代。”老师对我说：“只有祖国的富裕和强大，才能使幸福的生活之花永放光华”。祖国和她的人民，正如母亲和儿女，荣辱与共、血肉相连！我们的祖国，就是我们共同的母亲。我爱我的祖国，爱她五千年的璀璨历史，早在千年前我们的祖先就用《离骚》、《史记》、唐诗宋词充分展现了祖国的灿烂文化。我爱我的祖国，爱她如诗如画的山河美景。高山巍峨，暮色苍茫，长江黄河，五岳雄山……挺拔的高峰是祖国母亲清秀的面容；千万条河川是她流动的血脉；青藏高原更是那硬朗的脊梁。五千年光辉灿烂的文化；饮誉世界的四大发明；三山五岳的秀美江川，这一切怎能不让我们骄傲和自豪！更让我们为之骄傲的是我们的民族精神。
关于1月1日元旦的国旗下讲话
把握青春 展望未来敬爱的老师、亲爱的同学们：大家早上好！今天我在国旗下讲话的题目是“把握青春，展望未来”。迎着黎明的第一缕曙光，我们汇聚国旗下。望着冉冉升起的国旗，踏着青春的脚步，今日，我们又一次走到了展望未来的起点。明天就是元旦节了，你们知道元旦是什么意思吗？“元”是开始，第一之意，“旦”是早晨，一天之意。一年的第一天，所谓新年新气象，就是要我们以蓬勃的朝气和奋发的斗志来迎接崭新的一年。有人说，青春是人生中的一首歌，蓬勃的朝气拨动着我们年轻的心弦。有一天，时间老人来到人间，看到一个十六岁的小伙子无精打采，垂头丧气，而一个六十岁的老人却笑口常开，生机勃勃。
关于冬季长跑的国旗下讲话
敬爱的老师、亲爱的同学们：大家好，今天我国旗下讲话的题目是《冬季长跑启动仪式》冬天已经悄悄的到来，将会频繁出现气温下降的现象，这会让我们有点寒风刺骨的感觉吧，但是这个季节正是锻炼身体的好时机。冬季锻炼有很多方式，对我们而言，最简单的锻炼就是进行冬季长跑。先让我们简单了解冬季长跑的好处：长跑可提高呼吸系统和心血管系统机能，有利于防病治病。长跑能陶冶人的性格，磨练人的意志。长跑也可以使人情绪乐观饱满，有助于增进食欲，加强消化功能，促进营养吸收。
关于备战期中考的国旗下讲话
大家好，我是七(5)班的周欣吾桐，今天我演讲的题目是“争分夺秒，备战期中考”。同学们，时间匆匆，转眼间，又一个期中考的号角吹响了，面对下个星期的期中考，我们应该做些什么呢?首先，我们要好好利用时间，与时间赛跑。有人说：世界上最快的是时间;有人说：世界上最慢的也是时间;医生说：时间就是生命;农民说：时间就是粮食;同学们，我们说：时间就是知识，时间就是希望。同样的作业，同样的时间，有些同学不仅高效完成了老师布置的作业，还有空自行复习。可是有的同学却毫无目的，在有效的时间里做的都是无效的事情，这些同学其实没有充分利用好时间。要知道放弃时间的人，时间也放弃他。人生就像一条长长的跑道，一路上，如果你迟疑，如果你歇脚，如果你沿途睡个小觉，那么就会有很多人超越你，你就会被甩在队伍之后。
高考动员大会国旗下的讲话
尊敬的各位领导，老师，亲爱的同学们：早上好！今天。我国旗下讲话的题目是笑迎高考，轻松上阵。现在是5月20日。9点30分。对于高三的同学。18天后的我们已经坐在了高考的考场上，检验自己高中三年的成果，北大学子贺淑婷曾经发出过这样的感慨，人生再也不会有哪个时期，能够像高中时代一样，能够单纯的，专一的，几近固执的，而又饱含信仰和希冀的，心无旁骛乃至与世隔绝的，为了一个认定的目标努力。为理想奋斗的过程是幸福的，而面对高考，唯有拥有乐观的心态，饱满的精神，迈着轻松的步伐，才能将自己高中三年的积淀，发挥的淋漓尽致。
感谢您，亲爱的母校（国旗下讲话）
感谢您，亲爱的母校（国旗下讲话）尊敬的老师，亲爱的同学们：早上好！我是来自初三（15）班的xx。今天我讲话的题目是：《感谢您，亲爱的母校——xxx》。徜徉在校园的小路上，细细地看着周围的一切：三年的时间，新的教学楼建起来了，银杏树已经长得枝繁叶茂了，而我们也已不再是当年不谙世事的小孩子了。三年的初中生活，一千多个日日夜夜，听起来是那么漫长，但当我们真正意识到的时候，它已接近尾声。从三年前，我们第一次迈进这校门开始，学校对我们无微不至的关怀，如润物细雨，滋润我们的心田；如拂面春风，温暖我们的灵魂。三年来，我们在青竹湖一起走过的风风雨雨，而今将成为甜蜜的往昔。回首过去有太多记忆值得我们珍藏：课堂上，我们一起在知识的海洋中遨游；运动会上，我们一起在操场挥汗如雨；班歌比赛中，我们一起在舞台上展示自己的风采。那写满心底的，是留恋，是温馨，是感激。这三年中，我们健康、快乐地成长。而这一切，都与老师对我们的辛勤栽培是分不开的。记得武校长曾经说过：要把每一个学生放在心上！确实，每一位老师都是这样做的：不论工作再怎么繁忙，武校长总是会抽时间来了解我们的学习情况
感恩节国旗下的讲话：感谢有你
鲜花感谢雨露，因为有了雨露的滋润，它才能绽放；雄鹰感谢长空，因为有了长空的辽阔，它才能飞翔；鱼儿感谢大海，因为有了大海的广博，它才能畅游。感恩是一种姿态，是一种发现美并欣赏美的道德情怀。我们应该怀着一颗感恩的心，从平凡的生活中发现美。生命因感恩而美丽。感恩，这二个字，看似简单，在现实生活中，却很少有人能做到，甚至感恩已被人渐渐淡忘。想想我们自己，面对父母长辈无微不至的照顾，你是否想过感恩？面对老师耐心细致的教导，你是否想过感恩？面对朋友真心实意的帮助，你是否想过感恩？或许，被爱与关心环绕着长大的我们，内心对别人的付出与关爱早已麻木，我们总是觉得我们所得到的一切都是理所当然的，不需要理由，更不需要感恩。然而真的不需要感恩吗？看看我们身边的大自然，乌鸦反哺，羔羊跪乳，动物们尚能如此，那我们呢？我们更应该学会感恩。
关于全国爱眼日的国旗下讲话
关于全国爱眼日的国旗下讲话尊敬的老师，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?
国旗下讲话：做个文明的好孩子
寄语：以下是为大家准备的关于演讲稿的文章，希望可以帮助大家。尊敬的老师，亲爱的同学：早上好！在和煦的春风里，万里焕发了生命力。我们美丽的校园里也在悄悄地发生着变化。同学们在春天里变得活跃起来，课间爱在操场上奔跑和追逐，是的，生命在于运动。瞧，我们的老师已在操场南面的墙上为你们绘制了体育健儿运动的画面；不知道你们观察过没有，在植树节里，有许多棵树悄悄地在我们的校园里安了家，正迎着阳光雨露想和同学们一起茁壮成长；路旁的花坛里，小草欣欣然张开双眼，一切显得那么美好。可有的同学在玩耍时常爱用脚去踩无辜的小草，用手去摇可怜的小树。“小朋友，我们需要休息。等到夏天，我们会给你们浓浓的绿阴。”同学们，你们听了这样的声音，你还忍心打扰他们吗？
国旗下讲话：安全，永恒的主题
为大家收集整理了《 国旗下讲话：安全，永恒的主题》供大家参考，希望对大家有所帮助！！！各位老师、同学们：大家早上好!今天我国旗下讲话的题目是《安全，永恒的主题》。对于每个人来说，生命都只有一次。注意安全，就是善待和珍惜生命的一种有效途径，专家认为,通过教育和预防，80%的中小学生意外伤害事故是可以避免的。在这里,我向全校同学提出如下建议：一、遵守交通规则和交通秩序。来校、回家做到文明行路，出校门也不要边讲话、打闹，边骑车，要注意过往车辆状况；不闯红灯，过马路要机警，不走机动车道，不逆行；不骑自行车带人。
2024开展调研活动的工作总结
各级委（组）要高度重视调查研究工作，按照shiwei要求和总体部署，科学落实好本部门调查研究工作计划，从方案计划、过程实施、监督问效等各个环节入手，强化对调查研究工作的组织领导，形成委（组）主要负责同志负总责，班子其他成员各负其责，领导干部带头示范，广大员积极参与的生动局面。二要坚持科学统筹。调查研究是一项经常性的工作，也是一项长期任务。要加强统筹安排，避免扎堆调研、多头调研、重复调研，不增加基层负担。要深入践行实事求是的工作作风，“实”而更“实”、查“实”求“是”；要统筹好当前工作和长期工作的关系，学会“弹钢琴”，真正“走前列”，确保调查研究工作能“沉到底”、“沉够底”，掌握“解剖麻雀”、“管中窥豹”、“不唯上、不唯书、只唯实，交换、比较、反复”工作方法。

6. 例二：如图，AB是⊙O的直径，PA垂直于⊙O所在的平面，C是圆周上的一点，且PA＝AC，求二面角P－BC－A的大小． 解：由已知PA⊥平面ABC，BC在平面ABC内∴PA⊥BC∵AB是⊙O的直径，且点C在圆周上，∴AC⊥BC又∵PA∩AC=A,PA,AC在平面PAC内，∴BC⊥平面PAC又PC在平面PAC内，∴PC⊥BC又∵BC是二面角P-BC-A的棱，∴∠PCA是二面角P-BC-A的平面角由PA=AC知△PAC是等腰直角三角形∴∠PCA=45°，即二面角P-BC-A的大小是45°7.面面垂直定义一般地，两个平面相交，如果它们所成的二面角是直二面角，就说这两个平面互相垂直，平面α与β垂直，记作α⊥β8. 探究：建筑工人在砌墙时，常用铅锤来检测所砌的墙面与地面是否垂直，如果系有铅锤的细绳紧贴墙面，工人师傅被认为墙面垂直于地面，否则他就认为墙面不垂直于地面，这种方法说明了什么道理？
人教A版高中数学必修二平面与平面平行教学设计
1.探究：根据基本事实的推论2,3，过两条平行直线或两条相交直线，有且只有一个平面，由此可以想到，如果一个平面内有两条相交或平行直线都与另一个平面平行，是否就能使这两个平面平行？如图（1），a和b分别是矩形硬纸板的两条对边所在直线，它们都和桌面平行，那么硬纸板和桌面平行吗？如图（2），c和d分别是三角尺相邻两边所在直线，它们都和桌面平行，那么三角尺与桌面平行吗？2.如果一个平面内有两条平行直线与另一个平面平行，这两个平面不一定平行。我们借助长方体模型来说明。如图，在平面A’ADD’内画一条与AA’平行的直线EF,显然AA’与EF都平行于平面DD’CC’,但这两条平行直线所在平面AA’DD’与平面DD’CC’相交。3.如果一个平面内有两条相交直线与另一个平面平行，这两个平面是平行的，如图，平面ABCD内两条相交直线A’C’,B’D’平行。

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.
