我是来自高二六班的xx,非常荣幸能在国旗下代表上周值周班高二六班演讲。今天我演讲的主题是:安全——教育的保障。大家知道吗,三月二十六日是“全国中小学生安全宣传教育日”。 据权威数据显示,我国现有18岁以下未成年人亿人,平均每年意外伤害人数约为4000万人次,医疗费用亿元,平均每年约有万名中小学生非正常伤亡。为推动中小学安全教育工作,降低青少年伤亡事故的发生率,保证青少年健康成长。1996年由国家教育部、公安部等七部委联合发文,确定每年三月份最后一周的星期一作为全国中小学生“安全教育日”,每年确定一个主题。 如果说学生是祖国的花朵,安全就恰如花朵下的土壤,是花朵生长的保障。我的班主任常常教导我说:“一定要注意安全,父母把自己养这么大不容易。”直到我把脚歪到之前,我还不曾意识到安全的重要性。
1、结合具体生活场景,能运用所学的乘法口诀解决简单的实际问题,通过图与式的对应,进一步理解乘法的意义。 2、能熟练运用口诀进行计算,提高灵活运用口诀解决实际问题的能力。 3、体会数学与实际生活的联系,培养用数学的意识,体验口诀在解决问题中的作用。 运用所学乘法解决简单的实际问题。 结合实际情景理解乘法的意义。 1、口算: 5×2=10 6×2=12 8×5=40 2×7=14 5×9=45 3×5=15 2×6=12 2×9=18 4×2=8 2、谈话导入:在前面的学习中,我们认识了乘法,而且还学习了2和5的乘法口诀。这节课,老师想请同学们用这些跟乘法有关的知识来帮助老师一起解决生活中遇到的问题,一起来看一看吧。快乐休息时间到了,学校的大操场突然热闹起来了,你们一定非常喜欢课件活动吧!看,操场上同学们有的在玩老鹰捉小鸡的游戏,有的在进行乒乓球比赛,有的在跳绳,还有的在踢毽子……真热闹啊!
敬爱的老师们,亲爱的同学们:大家早上好!今天我国旗下讲话的主题是:诚信立人,感恩做人。如果你要掌管好自己的人生,请务必握牢手中的两张卡:一张是诚信的信用卡,一张是感恩的储蓄卡。诚信是一种美德,也是一种品质。仔细回想:你是否抄袭同学的作业,默写时是否看过书本,考试时是否有过作弊。但是,你是否想过,抄来的知识永远不属于自己,正如海涅说的“生命不可能从谎言中开出灿烂的鲜花”。对人守信,对事负责,让我们做个大写的诚信的人。如果说诚信是一种人生态度,一种精神境界,那么感恩就是一种处事哲学。我们有同学以青春期叛逆为借口,顶撞父母,甚至对父母恶语相向。请大家扪心自问:难道就因为父母爱我们,无限包容我们的错误,我们就可以肆意挥霍甚至抹杀那份爱吗?
尊敬的老师,亲爱的同学们,大家上午好;今天我演讲的题目是《勤奋成就人生》中国有句俗话,叫做“一勤天下无难事”。唐代大文学豪韩愈就曾说过:“业精于勤,荒于嬉。”也就是说,学业方面的精深造诣于勤奋好学,唯有勤奋者,才能在无边的知识海洋里猎取到真正的智慧。数学家华罗庚说:“勤能补拙是良训,一分辛劳一分才”;科学家爱迪生说:“巨大的成就,出于长期的勤奋”。这就告诉我们,勤奋才能成就人生。古往今来,多少名人雅士都是由于勤奋才成就了自己的伟大人生。孔子曾说自己勤于读书,以至发愤忘食,乐以忘忧。战国时期的苏秦正是由于悬梁刺股,勤奋读书,才终挂七国帅印。马克思写《资本论》,辛勤劳作,艰苦奋斗了四十年,阅读了数量惊人的书籍和刊物,做过一千五百种以上的笔记;我国数学家陈景润在攀登数学高峰的道路上,翻阅了国内外上千本有关资料,通宵达旦的看书学习,最终取得了震惊世界的伟大成就!而我们身边的同学也正是通过勤奋学习,才获得优异的成绩。可见,古往今来,任何一项成就的取得,都是和勤奋分不开的。一分耕耘一分收获,只有勤奋,才是扣开成功人生的敲门砖。
老师、同学们:大家早上好!在这乍暖还寒、春寒料峭的日子里,我们走进充满春天气息的三月。三月,是春风和煦、万木吐绿、百花盛开、欣欣向荣的美好季节,也是我们同学们长知识、长身体的最佳时节。我们一定要在这个美好的时节,珍惜每一寸光阴,听好每一堂课,做好每一道习题,吸收消化好每一点知识,不负这大好春光。三月,是文明礼貌月,我们每一个同学,要用自己的实际行动,播撒文明的种子,掀起文明的新风。说文明话,做文明事,当文明人。让清新的春风春雨洗涤我们的心灵,让一切野蛮、粗俗、丑陋的言行在我们身边消失。你的一句礼貌的问候,会给同学、老师带来如春风般的温暖;你弯腰从地上拣起一片纸屑,会给我们美丽的校园带来一片文明的春色。
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
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.

Ibelieved that I was right and he was wrong, and Tony believed that I was wrongand he was right. Our teacher, a kind and smart lady, decided to teach us alesson. She brought us to the front of the class and placed him on one side ofher desk and me on the other. In the middle of her desk was a large and roundobject. I could clearly see that it was black. The teacher asked us what colorthe object was. “White,” Tony answered. I couldn’t believe he said the objectwas white! “Clearly, it was black!” Another argument started between Tony andme, this time about the color of the object.

By usingthis method, the study found that red meats were the most unfriendly foods tothe environment. Keeping farm animals produces a large number of methane(甲烷)that keeps 30 times more heat than CO2. As well asmaking the earth warmer, eating too much red meat is known to increase the riskof a few illnesses, such as heart trouble.
各位老师、同学们:早上好!蓝天下,迎着初升的太阳,和着冬日的晨风,让我们感觉到了一丝冬的寒意。在庄严而又隆重的升旗仪式中,全体同学是那么严肃认真,我们一起眺望着五星红旗冉冉升起,一起歌唱着气壮山河的国歌,一起感受着福泉奥校全体师生的凝聚力……此时此刻,我感到非常激动,因为咱们又一次相聚在国旗下!为了这次国旗下的讲话,我思索了很久很久,最后决定和大家一起分享一篇文章“学会欣赏,为美丽喝彩”:我们身边的一事一物、一草一木,都有它独到的美的一面。让我们去寻找这些美,特别是那些小小的美,容易被我们忽略的美,让我们去发现他们,去欣赏他们、赞美他们吧!让我们为雏菊鼓掌。它开放在百花凋谢的秋季,花朵很小,星星点点,但却亮的抢眼,它拿出了积聚一生的灿烂,在阳光下展示自己的生命、自己的灵魂,这种全力以赴的精神令人感动。让我们为“墙角数枝梅,凌寒独自开”的梅花而感动吧,在寒冷的北方,大雪纷飞,只有梅花不畏严寒,傲然开放,这种“凌寒独自开”的品格令人赞叹!让我们为“野火烧不尽,春风吹又生”的小草而鼓掌,它们那顽强的生命力令人赞叹!
中国有句俗话,说“在家靠父母,出门靠朋友”。这句话包含了一个道理:当你无法独立完成一件事情的时候就需要借助别人的力量。按照现在流行的说法就是要合作。但是在我们现实生活中,你得问一问:我有朋友吗?有人愿意和我合作吗?一问起这个问题,有些同学就皱眉头了,因为仔细想想,呀,的确没有人愿意和我合作。那请你再仔细想想,究竟是为什么呢?老师来给你说说其中的原因吧。首先你反思自己,是不是一个讲文明、懂礼仪的学生。是的,只有讲文明、懂礼仪的学生才会受到别人的欢迎。别人才会愿意和你一起合作,一起学习,一起游玩,一起成长,一起进步。相信每个同学都清楚怎样的行为才符合文明礼仪的规定。你回忆一下自己的言行:向同学说过粗话吗,自己的手脚挥到过同学身上吗,课间的时候在教室、走廊飞快地跑过吗,乱扔过纸屑果皮吗,课桌椅上留过你的笔迹刀痕吗,老师布置的作业拖拉过吗,踩踏过草坪攀拉树枝吗……
