新学期国旗下讲话稿
老师们同学们：早上好！我们刚欢度了喜庆祥和的春节，又度过元宵节了。元宵节目前虽然还没有像除夕、清明、端午、中秋这四个传统节日一样被确立为国家法定假期，但从古至今，元宵佳节同样也承载了中华民族太多美好的希望和祝福，被历代文人墨客反复歌吟，具有深厚的历史底蕴和文化内涵。“三十的火，十五的灯”，元宵是热热闹闹中国年的“压轴戏”。这一天，一切活动的主题强调一个“闹”字。然而，这里面传承的是怎样的一种传统文化呢？下面请允许我作一个简单的介绍。正月是农历的元月，古人称夜为“宵”，所以称正月十五为元宵节。正月十五日是一年中个月圆之夜，也是一元复始，大地回春的夜晚，人们对此加以庆祝，也是庆贺新春的延续。天上明月，人间情怀，元宵节的明月这一特殊天象形成了中国人特有的月亮节、团圆节、狂欢节。元宵节也称灯节，元宵燃灯的风俗起自汉朝，到了唐代，赏灯活动更加兴盛，皇宫里、街道上处处挂灯，还要建立高大的灯轮、灯楼和灯树，唐朝大诗人卢照邻用“接汉疑星落，依楼似月悬”的诗句来描述元宵节燃灯的盛况，把元宵节燃灯比作天上明月、流星雨一样耀眼绚烂。
新学期国旗下讲话稿4篇
尊敬的老师们，亲爱的同学们：大家早上好！今天是2月x日，第一周星期六。伴随着春天的脚步，我们迎来了新学期的第一缕曙光。在新学期第一次举行升国旗仪式的早晨，我衷心祝愿各位教职工身体健康，工作顺利！衷心地祝愿各位学生学习进步，健康成长！“爆竹声中一岁除，春风送暖入屠苏。千门万户曈曈日，总把新桃换旧符。”认真参加过寒假古诗诵读的同学们一定很熟悉王安石的这首古诗《元日》和这首诗描写的人们过春节的场面，鞭炮声中，转眼间，一年已过，同学们，我们已经步入了小学阶段的最后一个学期，我们已从一个懵懂的幼儿步于少年的行列，即将踏入青年的门槛，这是人生最美好时光。宋代大诗人苏轼年青时候在大年夜守岁时发出时光匆匆流逝的感慨，“明年岂无年，心事恐蹉跎。努力尽今夕，少年犹可夸。”他想到一年年地度过，重要的是不要将自己的心事、理想、愿望随意蹉跎。努力就从今夕开始，趁着现在自己还是青春年少。同学们，今天国旗下讲话的主题是：“读书贵在少年时”。“黑发不知勤学早，白首方悔读书迟。”这两句出自唐代颜真卿的《劝学》一诗。告诫青少年朋友，应当珍惜大好的青春时光，发愤读书。人生中最可宝贵的，莫过于青少年时期。一个人的成功依赖于人在青少年时期的努力学习。
高中新学期国旗下讲话稿
尊敬的各位老师、亲爱的同学们：早上好!我今天高中新学期国旗下讲话稿的题目是：革命传统精神代代相传“孩子们，喜欢过生日吗?”“因为生日有小礼物，是吗?”“喜欢过节吗?”“因为过节有压岁钱,是吗?”现在社会发展了,生活水平提高了.你们的生活也非常优越，甚至有些同学不用等到过生日，过节，平时就有属于自己的零花钱，但是对于过去的艰苦生活，你们了解吗?同学们，抬头看看用战士们的鲜血染成的五星红旗吧!透过鲜红的五星红旗，你是否又看到了在军阀铡刀前毫无惧色的刘胡兰;你是否又感受到了江姐在敌人酷刑下那撕心裂肺的痛楚;你是否又听到了英雄“为了胜利，向我开炮!”的豪迈呐喊。
北师大初中七年级数学下册用尺规作角教案
解析：①以O为圆心，任意长为半径作弧交OA于D，交OB于C；②以O′为圆心，以同样长(OC长)为半径作弧，交O′B′于C′；③以C′为圆心，CD长为半径作弧交前弧于D′；④过D′作射线O′A′，∠A′O′B′为所求．解：如下图所示．【类型三】 利用尺规作角的和或差已知∠AOB，用尺规作图法作∠A′O′B′，使∠A′O′B′＝2∠AOB.解析：先作一个角等于∠AOB，再以这个角的一边为边在其外部作一个角等于∠AOB，那么图中最大的角就是所求的角．解：作法：①作∠DO′B′＝∠AOB；②在∠DO′B′的外部作∠A′O′D＝∠AOB，∠A′O′B′就是所求的角(如下图)．三、板书设计1．尺规作图2．用尺规作角本节课学习了有关尺规作图的相关知识，课堂教学内容以学生动手操作为主，在学生动手操作的过程中要鼓励学生大胆动手，培养学生的动手能力和书面语言表达能力
北师大初中九年级数学下册垂径定理教案
方法总结：垂径定理虽是圆的知识，但也不是孤立的，它常和三角形等知识综合来解决问题，我们一定要把知识融会贯通，在解决问题时才能得心应手．变式训练：见《学练优》本课时练习“课后巩固提升”第2题【类型三】 动点问题如图，⊙O的直径为10cm，弦AB＝8cm，P是弦AB上的一个动点，求OP的长度范围．解析：当点P处于弦AB的端点时，OP最长，此时OP为半径的长；当OP⊥AB时，OP最短，利用垂径定理及勾股定理可求得此时OP的长．解：作直径MN⊥弦AB，交AB于点D，由垂径定理，得AD＝DB＝12AB＝4cm.又∵⊙O的直径为10cm，连接OA，∴OA＝5cm.在Rt△AOD中，由勾股定理，得OD＝OA2－AD2＝3cm.∵垂线段最短，半径最长，∴OP的长度范围是3cm≤OP≤5cm.方法总结：解题的关键是明确OP最长、最短时的情况，灵活利用垂径定理求解．容易出错的地方是不能确定最值时的情况．
