国旗下讲话：做个文明的好孩子
寄语：以下是为大家准备的关于演讲稿的文章，希望可以帮助大家。尊敬的老师，亲爱的同学：早上好！在和煦的春风里，万里焕发了生命力。我们美丽的校园里也在悄悄地发生着变化。同学们在春天里变得活跃起来，课间爱在操场上奔跑和追逐，是的，生命在于运动。瞧，我们的老师已在操场南面的墙上为你们绘制了体育健儿运动的画面；不知道你们观察过没有，在植树节里，有许多棵树悄悄地在我们的校园里安了家，正迎着阳光雨露想和同学们一起茁壮成长；路旁的花坛里，小草欣欣然张开双眼，一切显得那么美好。可有的同学在玩耍时常爱用脚去踩无辜的小草，用手去摇可怜的小树。“小朋友，我们需要休息。等到夏天，我们会给你们浓浓的绿阴。”同学们，你们听了这样的声音，你还忍心打扰他们吗？
国旗下讲话：安全，永恒的主题
为大家收集整理了《 国旗下讲话：安全，永恒的主题》供大家参考，希望对大家有所帮助！！！各位老师、同学们：大家早上好!今天我国旗下讲话的题目是《安全，永恒的主题》。对于每个人来说，生命都只有一次。注意安全，就是善待和珍惜生命的一种有效途径，专家认为,通过教育和预防，80%的中小学生意外伤害事故是可以避免的。在这里,我向全校同学提出如下建议：一、遵守交通规则和交通秩序。来校、回家做到文明行路，出校门也不要边讲话、打闹，边骑车，要注意过往车辆状况；不闯红灯，过马路要机警，不走机动车道，不逆行；不骑自行车带人。
在全市两违工作会议上的讲话
同志们：这次全市清理违建工作会议，是在特殊形势下召开的一次下决心、动真格、打硬仗的专题会议。今年以来，市委多次召开会议，研究部署违建清理工作，并先后组织开展了几次大规模的专项行动，有力刹住了非法占地抢建之风，遏制了“两违”的蔓延势头。在看到成效的同时，我们更要清醒地认识到，现在违建的歪风开始重新抬头，从中心市区到城乡结合部，再到周边乡村，都不同程度地存在。这不仅严重阻碍了项目落地，阻碍了城市发展，影响了社会和谐稳定，从根本上说也损害了大多数人民群众的利益。之所以出现这些现象，我认为主要有以下几个原因：一是住房需求。在房价走高的情况下，一些人心存侥幸、铤而走险，违法违规建设住房。二是利益驱使。一些人“以房生财”，或用来出租经营，私自违建、高价出售；或为牟取超额拆迁补偿费用，顶风作案。三是执法不严。部门齐抓共管格局的合力没有形成，网格化管理责任没有落实到位，“清违”工作时紧时松，致使违建者对“清违”行动持怀疑态度，等待时机“东山再起”。还有，在同一片区的违建房，有的拆了，有的没拆，导致群众认为执法就是欺负老实人，“找人、说情、送礼”就可幸免于难。
2024年上半年工作总结会议上的讲话
分管领导要紧紧围绕“三保”（保安全、保质量、保进度）目标任务，靠前指挥、倒排工期、挂图作战，从项目建设的具体问题入手，以钉钉子的精神抓重点、抓关键、抓核心，加大施工现场巡查频次，及时协调处理和跟进服务，确保按期完成×××××××、×××××××等民生项目。紧盯×××××××，加快工程进度，完工的尽快组织验收结算。主动对接、加强服务，确保×××××××按期完成年度建设任务，尽快交付使用。二是科学谋划城乡建设重点工程，准确把握国家、省、市关于项目建设的具体要求，吃透政策、把握导向、聚焦需求，围绕×××××××基础设施布局方向，提前启动明年×××××××、×××××××等重点项目的摸底调查和前期手续办理工作，确保×××××××项目落地实施。四、聚焦主业、守牢底线，全面完成各项既定目标。

人教版高中地理选修1月球和地月系教案
月球对地球的意义月球与地球形影相随，关系密切。月球对地球的影响，主要有以下几方面：1．地球上夜晚的自然照明，主要靠月亮。2．远在古代，人们就根据月相变化的周期，编订历法。我国农历月份的安排，是以月相变化 周期为标准的。农历规定朔为初一，这样，望就在十五日或十六日。我国人民的传统节日，像春节、中秋节就是按农历的月日计算安排的。3．由于地球表面各处所受月球和太阳引力的不同，地球上的水体产生了明显的潮汐现象。4．月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏；重力较小；没有大气层，利用太阳能的条件较好。如何利用月球的特殊环境，开发月球的资源，以及如 何利用月球作“码头”，使人类更好地研究宇宙，这将是月地关系的新篇章。

5.对土星五号火箭和登月舱的质疑现代航天飞机只能把20吨载荷送上低轨，而当 年的土星五号却能轻而易举地把100吨以上载荷送上地球轨道，将几十吨物体推出地球重力圈，为什么后来却弃而不用，据说连图纸都没有保存下来？6.温度对摄影器材的影响月面白天可达到121°C，据图片看，相机是露在宇航服外而没有采用保温措施的。胶卷在66°C就会受热卷曲失效，怎么拍得了照片？这些人士认为，对以上这一切美国政府一直没个 交代，而知情者由于担心生活和安全受到影响，甚至可能直接遭到了胁迫，至今对此沉默不言。但相信不久的将来，诞生于美苏太空竞赛年代的“登月骗局”定会水落石出。反驳不过，也有许多人认为“阿波罗”登月计划不可能造假：首先因为该计划当时是在全球实况转播的，近亿人亲眼看到。另外，宇航员还从月球带回了一些实物，如岩石。

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful!

Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

Finish Exercise 4 on Page 15 of the textbook.A smart home is one that integrated computers into the structure of the building itself. In this way, many of the things that we now do ourselves become automatic. For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on and off, and so that your home would be more energy-efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.

在全市老旧小区改造工作座谈会上的讲话
一加快老旧小区改造，是“推动城市发展由外延扩张型向内涵提升型转变”的内在要求。综观发达国家包括国内先进地区的城市化之路，无一不是从数量扩张走向质量提升的。我们要深刻认识到，土地的刚性约束从根本上决定了城市空间不可能无限扩张。经过多年发展，X建成区整体框架已经全面拉开，当前我市绕城高速公路围合区域内的X平方公里已基本铺满，城市要发展必须向“内”要潜力、要空间。同时由于历史原因，老城区与新城区在规划设计、基础设施等方面的差距不断拉大，城市内部的“二元结构”日益显现，拉低了城市现代化的整体水平。
