《点滴铸就成功，习惯成就未来》国旗下的讲话范文
我今天讲话的题目是“点滴铸就成功，习惯成就未来”，生活中，我们仰慕优秀的人，我们都渴望自己也成为一个优秀的人，但又似乎感觉优秀是一个遥不可及的目标，很难达到。其实，优秀离我们并不遥远，优秀体现在你我的一言一行之中，体现在一件件不起眼的小事之中。著名教育家叶圣陶先生说过这样一句话：“什么是教育?简单一句话，就是要养成习惯。”我们在学校，不仅要学好科学文化知识，更要进行能力培养，良好习惯的养成。怎样培养自己的好习惯?首先需要检查一下自己，反省一下自身的一些坏习惯。你是否留意到居家学习的这段时间以来，时间总是不知不觉中就过去了?我们刚打开书本想要认真学习，突然被旁边的琐碎事情吸引了注意力，就无法再专心学习?这一些都是阻止我们变优秀的坏习惯。那我们应该如何改正自己的缺点，培养良好的行为习惯呢?简单来说就是用好习惯代替坏习惯，这里给大家几点建议：
（世界水日）老师在国旗下的讲话：节水护水——让生命之水长流
水是生命之源，是人类生存离不开的宝贵资源。科学家曾做过这样一个试验：假如一个人不吃任何食物，生命可以维持二十多天，而若是不喝水，过不了一个星期就可能死亡。对于地球上的所有生灵来说，离开了水就意味着疾病、饥饿和死亡。上有天堂，下有苏杭，因为苏州有秀美的山峰与一碧千里太湖之水而被冠以天堂之城的美誉。东山，一座三面环山环水的古朴小镇，更是被誉为天堂中的天堂。多少年来，太湖水哺育了千千万万的东山人。记得老师小时候所喝的水是直接从太湖中提取加热的，可现在，我们所喝的水虽然也来自太湖，可是却经过了许多道工序的处理，静心一闻，还能闻到漂白粉的味道。这是因为我们赖以生存的太湖水已经被污染了。超负荷养殖、污水排放、太湖旅游的过渡开发，在人们感受到眼前的利益的同时，也在破坏子孙后代的生存环境。去年，大规模的无锡蓝藻爆发，已经给人们敲响了环保的警钟。为了更好的保护太湖水，我们东山实小的全体师生积极行动起来，在3月10日进行了“认捐花白鲢，洁净母亲湖”捐款仪式。捐款活动虽然已经结束，但我们保护太湖水，洁净太湖水的行动将一直延续下去。
“世界艾滋病日”国旗下的讲话：增强自我保护意识
作为一个青少年，应该认识到：艾滋病的传播没有国界，我国是世界上的人口大国，是国际社会的一员，有责任和世界各国携手共同努力控制艾滋病的蔓延；学习预防艾滋病的知识，不仅使青少年能及时了解与掌握预防艾滋病的知识、增强自我保护意识和抵御艾滋病侵袭的能力；更重要的是培养预防艾滋病的社会责任感、使命感。青少年是社会和国家的未来，是全社会预防艾滋病的主力军。青少年参与预防艾滋病的活动意义深远，不仅是为了青少年自己的生存与健康，而且是为了全社会、全人类的发展。青少年有责任成为抵御艾滋病在二十一世纪猖獗流行的最有生气的社会力量。
国旗下的讲话:让成功在和谐校园里激励我们前行
伴随着国旗冉冉升起，我们伟大的祖国在祥和庄重的氛围中度过了63周岁的华诞。在举国欢度国庆节的前夕，在刚刚过去的9月25日21时10分04秒，神州七号载人飞船带着翟志刚、刘伯明、景海鹏三位宇航员一飞冲天，带着中华民族克服冰雪灾害以及汶川地震的百折不挠的精神、带着成功举办奥运会、残奥会的顽强拼搏精神，骄傲地向太空宣誓：太空漫步，我们中国人来了！当五星红旗在太空、在翟志刚的手上傲然挥舞时，我们已经成功地成为世界上实现太空行走的第三个国家。身处伟大的祖国，我想每一个中国人、包括全校师生心底的那种豪迈无法用语言来形容。今天，我们度过国庆七天长假重新回到校园，我们同样要勾勒出我们自己的成功路径。1276名08级同学通过9月份的试读考查，即将陆续取得xx市xx商业学校的学籍；1193名07级同学正式进入主攻专业技能的第二学年；06级高考班45同学进入了冲刺的第三年，他们在新学期动员大会说有信心“用勇气刷新成绩”
国旗下的讲话 让安全与我们同行,让生命放出异彩
第一篇：尊敬的各位老师,亲爱的同学们:大家上午好!今天我发言的题目是:《让安全与我们同行,让生命放出异彩》又是一个草长莺飞,鸟语花香,万物复苏,春意盎然的季节;又到了我们学生校内游戏,郊外踏青,城里观光,远方旅游的好时节.那我不禁想到:在这一系列愉快的活动中,你想到安全问题了吗你的安全意识增强了吗面对活动中的一切不安全问题,你准备好了吗……同学们,每年三月的最后一个星期一被定为全国中小学生"安全教育日",今天是第十一个"安全教育日",今年的主题是"珍爱生命,安全第一".安全工作历来是学校工作的一个重要组成部分.据报道,我国每年约有1.6万名中小学生非正常死亡,中小学生因安全事故,食物中毒,溺水,自杀等死亡的,平均每天有40多人,就是说每天有一个班的学生在"消失".安全事故已经成为14岁以下少年儿童的第一死因.可见,珍爱生命,防止校园伤害,创建"平安校园"是多么重要啊!
关于倡导低碳生活，打造绿色校园的国旗下讲话
倡导低碳生活，打造绿色校园xxx班 xxx亲爱的老师，同学们：早上好!我是xxx班的xxx。今天，我国旗下讲话的题目是《倡导低碳生活，打造绿色校园》。现在我国正在积极倡导“低碳生活”。所谓“低碳生活”，就是指生活中所耗用的能量要尽力减少，从而减低二氧化碳的排放量。我们应该积极提倡并去实践低碳生活，要注意4个节约：节电、节水、节油、节气，从这些点滴做起。也许有同学会问，节能减排，应该是政府和企业关注的事，似乎和我们学生无关。那你就错了，社会大家庭中的每一个人，都与这件事密切相关！大家知道吗？如果人人养成随手关灯的好习惯，那么全国每年可节电约20亿千瓦时，减排二氧化碳188万吨。如果每年全国有10%的纸巾使用改为手帕代替，那就可减少纸张消耗约万吨，节能2万吨的标准煤。现实生活中，我们每节约一滴水，一度电，一张纸，一粒粮食，都是对环保的贡献；生活垃圾的合理处理，废旧电池的合理回收，对校园及其他公共绿地的爱护，对身边有损环保现象的劝阻……所有这些，都是我们应尽的社会责任。

读书节国旗下讲话：让读书成为最美好的生命举止
尊敬的老师、同学们：早上好！今天，我发言的题目是《让读书成为最美好的生命举止》春暖花开的四月，我们将迎来xx三中的第六届读书文化节，每年的这个季节，我们的校园繁花盛开书香飘逸，鲜花装点校道，书香涵养性灵。让我们一同走进翰墨书香的世界，不为分数，不为排名，只因为，阅读，确确实实是一项最美好的生命举止。古人说，书中自有黄金屋，书中自有颜如玉。不可否认，书籍能让我们增长知识和才干，能给我们的未来打下坚实的基础，能给我们带来许许多多可以触摸、可以预期的利益。然而，在这个花香满园的四月，我更愿意提倡同学们去读那种能让人心灵沉静，能促人思考，能给人智慧的书。宋代黄山谷说：一日不读书,尘生其中；两日不读书,言语乏味；三日不读书,面目可憎。就我的理解，这里所说的如果不读就会让人面目可憎的书，不会是那些能产生立竿见影效果的工具书或各类方法大全，也不会是我们许多同学曾经心爱的《知音漫客》或者各类练习册、试题集，而是像曹雪芹的《红楼梦》、罗曼罗兰的《名人传》、培根的《培根论说文集》、摩罗的《悲悯情怀》这样的书

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

空间向量基本定理教学设计人教A版高中数学选择性必修第一册
反思感悟用基底表示空间向量的解题策略1.空间中,任一向量都可以用一个基底表示,且只要基底确定,则表示形式是唯一的.2.用基底表示空间向量时,一般要结合图形,运用向量加法、减法的平行四边形法则、三角形法则,以及数乘向量的运算法则,逐步向基向量过渡,直至全部用基向量表示.3.在空间几何体中选择基底时,通常选取公共起点最集中的向量或关系最明确的向量作为基底,例如,在正方体、长方体、平行六面体、四面体中,一般选用从同一顶点出发的三条棱所对应的向量作为基底.例2.在棱长为2的正方体ABCD-A1B1C1D1中,E,F分别是DD1,BD的中点,点G在棱CD上,且CG=1/3 CD(1)证明:EF⊥B1C;(2)求EF与C1G所成角的余弦值.思路分析选择一个空间基底,将(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)证明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?与(C_1 G) ?夹角的余弦值即可.(1)证明:设(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,则{i,j,k}构成空间的一个正交基底.
倾斜角与斜率教学设计人教A版高中数学选择性必修第一册
(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).
