第二十个全国中小学生“安全教育日”国旗下讲话稿
老师们、同学们，上午好！今天是第二十个全国中小学生“安全教育日”，所以，今天我讲话的题目是《珍爱生命，安全第一》，教育部长周济曾讲过这么一句话：“没有安全，何谈教育”，的确是这样，没有校园安全，哪来教育事业的发展。校园安全不但关系到每位同学能否健康成长，也关系到每个家庭的幸福。因此,我们必须清醒的认识到“安全无小事”。但校园安全事故每天都在上演，校园安全问题成了永恒的话题。楼道踩踏、食物中毒、溺水身亡、交通安全、违规用电、火灾火险、体育运动、网络交友、打架斗殴、流感病毒、毒品危害等等，这些校园安全事故时刻威胁着我们青少年学生的健康成长。下面我们听一听这些触目惊心的安全事故。XX年12月7日湖南省湘潭育才中学发生惨重的校园踩踏事件，一名学生在下楼梯的过程中跌倒，引起拥挤踩踏，造成8人死亡，26人受伤。XX年12月2日，山东东营某学校校车侧翻事故造成3名学生死亡。XX年12月8日，安徽省淮北市同仁中学篮球场边的高墙轰然坍塌，5名女同学的花季生命被永远定格在哪里。XX年4月27日，辽宁省葫芦岛市某中学6名学生校外私自游泳，溺水死亡。
第二十一个全国中小学生安全教育日校长国旗下讲话稿
老师、同学们：早上好！今天是第21个全国中小学生安全教育日，今年中小学学生安全教育日主题是“强化安全意识，提升安全素养”，我们学校把这一周定为安全教育周，主题是生命教育。学校根据这一主题将开展一系列的活动，各个班级要开好一个生命教育的主题班会，出好一期黑板报，同学们要阅读一本或一篇有关生命教育的书籍或资料；进一步认识生命，树立正确的生命观，欣赏生命、尊重生命、敬畏生命，直至热爱生命，以达到激发生命的潜能，提升生命的品质，捍卫生命的尊严；感受生命的美好，唤起生命的热情，体认生命的意义，实现生命的价值；学会对他人生命的尊重、关怀和欣赏，树立积极的人生观。同学们，生命最大的特征是“生生不息”，我们的生命源于父母，对父母要有感恩之情、思念之情、亲爱之情。“仁者爱人”，要从与自己最亲近的人爱起，扩展到爱他人，爱社会，爱万物。要明白生命之成长必扎根于社会文明、文化与传统的土壤中，与他人、与过去现在未来之一切人的生命相依相系。
新人教版高中英语必修3Unit 1 Festivals and Celebrations-Reading for writing教学设计二
Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well－organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation？

人教版高中数学选修3排列与排列数教学设计
4.有8种不同的菜种,任选4种种在不同土质的4块地里,有 种不同的种法. 解析:将4块不同土质的地看作4个不同的位置,从8种不同的菜种中任选4种种在4块不同土质的地里,则本题即为从8个不同元素中任选4个元素的排列问题,所以不同的种法共有A_8^4 =8×7×6×5=1 680(种).答案:1 6805.用1、2、3、4、5、6、7这7个数字组成没有重复数字的四位数.(1)这些四位数中偶数有多少个?能被5整除的有多少个?(2)这些四位数中大于6 500的有多少个?解:(1)偶数的个位数只能是2、4、6,有A_3^1种排法,其他位上有A_6^3种排法,由分步乘法计数原理,知共有四位偶数A_3^1·A_6^3=360(个);能被5整除的数个位必须是5,故有A_6^3=120(个).(2)最高位上是7时大于6 500,有A_6^3种,最高位上是6时,百位上只能是7或5,故有2×A_5^2种.由分类加法计数原理知,这些四位数中大于6 500的共有A_6^3+2×A_5^2=160(个).

人教版高中政治必修1第二课多变的价格教案
（四）反思总结，当堂检测。本节内容讲述了价格变动对人们生活、生产的影响作用，主要知识框架如下：（1）、价格变动会影响人们的消费需求，商品价格上涨，人需求就减少，反之，则增大。价格变动对不同商品需求影响程度是不一样的，对生活必需品的需求量影响较小，对高档耐用品的需求量影响较大。相关商品价格变动对消费需求的影响不同，某种商品价格上涨，就会减少需求量，其替代品需求量增加，其互补品需求量则减少。（2）、价格变化也会影响生产经营，价格变动会调节生产，刺激生产者改进技术，提高劳动生产率，促使生产者生产适销对路的高 质量产品。（五）发导学案、布置预习。预习第三课第一框《消费及其类型》，完成预习导学案练习题九、板书设计《价格变动的影响》1、对人们生活的影响（1）商品价格变动与消费需求量之间的关系（2）不同商品的需求量对价格变动的反应程度不同
初二学生国旗下讲话稿——告别童年，走向成熟
大家好！我是来自初二（9）班的吴佩臻，今天我国旗下的讲话题目为“告别童年 走向成熟”两天后，就是儿童节了，首先我在这里祝大家儿童节快乐。而对于我们初二的同学们来说，这是最后一个儿童节，也将标志着我们告别童年，带着早已沸腾在血液中的成熟，早已准备着跳动青春的气息，真正地成为一名青少年，去拥抱五岁的天空。时光荏苒，蓦然回首，这十几年，我们在成长的道路上，印下了一个个或大或小或深或浅的足迹。十几年来，我们用天真烂漫的情怀，编织了一首人生中最难以忘怀的童年之歌。还记得月光下和小伙伴在庭院里洒下的咯咯笑声吗？那是我们快乐的童年。还记得冲刺外校前奔波于各个培优点之间的匆匆身影吗？那是我们紧张忙碌的童年。还记得刚入校时我们无法适应新生活而挂在嘴边的声声抱怨吗？那是我们受挫的童年。
小班数学教案
2、初步培养观察力和动手能力，萌发对科学活动的兴趣。 3、养成自己整理鞋子的良好习惯。 重点：按鞋子的大小、颜色、款式等特点进行配对。 难点：寻找鞋底的秘密，特别是形状：两头大中间向里凹，但两只鞋子的朝向是相反的。 二、活动准备： 1、与幼儿人数相近的大小、颜色、款式各异的鞋子散落放在鞋架上，用布先遮起来，人手一张白纸。 2 、欢快的音乐一段。 3、半圆形的座位安排，中间留有空地，便于活动。 三、活动过程 （一）奇怪的鞋子 1、教师以故事的形式引出：娃娃家里的宝宝呀，特别爱漂亮，她每天都要换一双新鞋子，所以她的鞋子特别多，最后，连她自己都分不清哪两只是一双了，有一天他穿了一双很特别的鞋子，一只是大的红鞋子，一只是小一点儿的花鞋子（教师边讲边出示两只鞋子），可是这一天，她非常不开心，你们知道她为什么不开心吗？（幼儿猜测，引导幼儿发现两只鞋子的不同） 2、教师小结：两只大小不同、形状不同、颜色也不一样的鞋子不是一双，所以穿的人当然就不舒服了。 （二）我的鞋子 1、师：那我们穿的鞋子是怎样的，它有什么特别的地方呢？ 2、引导幼儿观察、比较自己脚上的鞋子，鼓励幼儿大胆地说说自己鞋子的特别之处。（着重从鞋子的外型、颜色、大小等特点来观察） 3、师：我们穿的鞋子的大小相同，颜色一样，款式也一模一样。除了这些秘密外，它还有什么特别的地方呢？

北师大初中九年级数学下册利用三角函数测高2教案
问题2、如何用测角仪测量一个低处物体的俯角呢?和测量仰角的步骤是一样的，只不过测量俯角时，转动度盘，使度盘的直径对准低处的目标，记下此时铅垂线所指的度数，同样根据“同角的余角相等”，铅垂线所指的度数就是低处的俯角.活动三：测量底部可以到达的物体的高度.“底部可以到达”，就是在地面上可以无障碍地直接测得测点与被测物体底部之间的距离.要测旗杆MN的高度，可按下列步骤进行：(如下图)1.在测点A处安置测倾器(即测角仪)，测得M的仰角∠MCE=α.2.量出测点A到物体底部N的水平距离AN＝l.3.量出测倾器(即测角仪)的高度AC＝a(即顶线PQ成水平位置时，它与地面的距离).根据测量数据，就能求出物体MN的高度.在Rt△MEC中，∠MCE=α，AN=EC=l，所以tanα= ，即ME=tana·EC＝l·tanα.又因为NE＝AC＝a，所以MN＝ME+EN＝l·tanα+a.
