As thegovernment encourages the renaissance (复兴) of traditional culture,Hanfu is getting more and more popular with the teenagers. Every year, we canenjoy different Hanfu shows around the cities. And now quite a few Hanfu clubshave been set up in universities. Members usually wear Hanfu at theirgraduation ceremonies or during holidays. Some even wear Hanfu on regular days,too.

We allknow that rice, wheat and corn are staples, but do you know there is anotherkind of staple food—potatoes? Potatoes have many advantages. Theyare a good source of vitamin C and potassium(钾). A potato’s vitamin C isas rich as 10 apples. What’s more,potatoes are low in calories(卡路里)-onlythree fourths of the same amount of wheat and corn, according to People’s Daily. Potatoes are easy togrow. It can be grown in both the north and the south during winter, spring andautumn. The plant is also able to bear drought(干旱). Some areas of China arefacing water shortages, so the potato is safe to grow.

Oneday, Yu took a boat to an island, he was so hungry that he used an earth pot tocook meat. After the meat was well-done in boiled water, he didn’t want towaste time to wait for it to cool, so he took two branches to pick up the meatfrom the soup. After, to save time, he always took small branches to take outfood from the hot pot. For a long time, he was skilled at picking up food withsmall sticks. In this way, the first types of chopsticks were born.

尊敬的各位老师、同学们:大家好!今天,能站在国旗下讲话,我感到很荣幸。我演讲的题目是《不经历风雨怎能见彩虹》 乒乓球比赛虽然已经结束两周了,可我仍记忆犹新。我作为四年级唯一的女生代表学校参赛,虽然最后只取得了女子甲组的第10名,但是我觉得,在这场比赛中,我是一个赢家。 因为面对那些年龄比我大、个子比我高、打球时间比我长、技术比我好的对手,我并没有胆怯,在赛场上,我沉着应战,敢打敢拼,打出了我们三小的风格,打出了我们三小人的精神。 回想起集训的那段日子,真是苦不堪言。课间操、体育课、从第二节自习到8点,我都泡在了球馆里,星期六、日更是如此。但我从不言苦,我深信一分耕耘,一分收获。
今天是3.23,引来了第55个世界气象日。世界气象日又称国际气象日,是世界气象组织在1960年决定把3.23定为世界性纪念日,每年确定一个主题。中国是世界气象组织的创始国之一。今年气象日的主题是“气候知识服务气候行动”。恰逢今天是xx高中第四周国旗下讲话,G1407班童泽轩同学以环保为主题,向大家介绍了世界气象日的有关信息。由于天气原因,国旗下讲话改为广播会议。世界气象日,与孩子们一起亲近气象——记xx第四周国旗下讲话童泽轩同学在演讲中说到,绿色环境是健康自然的一种象征,绿色能带给我们生机、带给我们活力,而绿色校园中的绿色也不就只是一种颜色那么简单。走进我们如今洋溢着书香味的校园,你会被那迷人的风景所吸引。漫步在校园里这一派绿景下,会使你感到精神振奋、心情舒畅。校园中的绿色风景,对我们是及其有益的。一节课后,站在走廊上看看校园中的绿,让我们精神达到更高更好的状态!在课余时间,同学们又可以在校园小道上走走,看看周围的景物,不是有着置身花园之感吗?
《秋天的雨》是统编版教材三年级语文上册第二单元的一篇精读课文,是一篇抒情意味很浓的散文,名为写秋雨,实在写秋天。课文把秋雨作为一条线索,将秋天众多的景物巧妙地串起来,从整体上带出一个美丽、丰收、欢乐的秋天。使学生通过课文生动的描写,体会秋天的美好,感受课文的语言美。这是编选这篇课文的主要意图,也是本篇课文的教学重点。课文使用了多种修辞手法,或把秋雨人格化,或把秋雨比喻成生活中常见的东西和事物,或很含蓄地抒发感情,这些被艺术化了的语言,会给学生造成理解上的困难,是教学上的一个难点。
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.

篇一:XX年秋季学期小学开学典礼讲话老师们、同学们:大家好!今天是开学第一天,满怀新学期的喜悦,带着对积极向上的校园生活的向往,我们又走到了一起。我首先代表学校,向新入学的一年级学生表示热烈祝贺与诚挚的欢迎!同学们,新学年走进校园,你有没有发现,我们的校园里又有了新的变化——那就是学校东西两边的围墙上布置了“临浦一小名人墙”和“三色工程系列图片”。我们希望每一位一小的学子了解一小的历史,知道自己的责任。临浦一小建于1904年,百年的砥砺成长,百年的春华秋实,学校积淀了丰厚的人文文化。历史演义作家蔡东藩、音乐教育家桑松青等先贤曾在一小任教。北大著名教授、历史学家柴德赓,中国共青团创始人俞秀松,著名学者喻守真都是我们的校友,他们的人生理想曾在这里启航。近年来,一小正在着力打造“守真”教育品牌,取名“守真”,一为纪念校友、著名的注释家喻守真,追慕其做学问之真;二则蕴含着我们的办学追求,即“志在求真,恪守不违”。我们追求平实、真实的学校教育管理,要求老师“传真知,动真情,做真师”,要求学生“诚实、朴实、踏实”,我们的底气是来自一小百年辉煌的办学成绩和优良的教风——民国时期一小获省教育厅褒奖“学风纯美冠南乡”;解放后的萧山教育四柱之一;近年来我校在区年度考核中连年获片第一。当然,打造守真教育品牌这需要一种自信,一种底气,但更需要一种信念。
