关于公民素质的国旗下的讲话
公民素质，从点滴做起老师、同学们:大家早上好。今天晨会我讲话的题目是《公民素质，从点滴做起》。最近我们学校各班都已在开展“公民素质教育实践活动”，通过班主任老师组织、我们学生观察、参与、调查调研的自主学习形式， 围绕公民素质核心要素开展实践活动。那么我下面要讲一讲开学这三周来，我在校园内看到的几个现象：1、 早上在校园走廊内总能看见几张废纸或零食袋，走廊图书角的书横七竖八的乱丢在书架上，让人看着不舒服。2、 教室里老师讲台上乱七八糟放着作业本、试卷、甚至还有昨天午托吃剩的水果皮。3、 下课后个别同学在走廊上嬉笑追打、不时夹着难听的不文明用语。4、 洗手间的纸巾被同学随意扯拽，浪费水、不珍惜用纸的现象频频出现；以上的这些现象不知道是不是已经有同学拿着相机记录下来，是不是作为你们小组开展公民素质教育实践活动的研究问题。
关于励志和勤奋的国旗下的讲话
励志和勤奋是成才的必由之路老师、同学们：早上好！今天我演讲的题目是《励志和勤奋是成才的必由之路》。“励”是鼓舞，劝勉，“志”是关于将来要有所作为的意愿和决心，是有识之士的心愿，“励志”是激发文气，以求有所作为的意思。励志，首先要有志向，有高尚远大理想和明确的奋斗目标。其次，励志一定要有实践，要这实现志向而进行不懈的努力。少年周恩来在全班同学面前表明了自己的心迹：要“为中华这崛起而读书”，而当时与他同班的其他同学读书的目的是为明理，为做官，为挣钱，为吃饭，只是为了满足个人修养和生活的需要，而周恩来不愿意自己的民族再软弱，不愿意自己的同胞受欺辱，他把个人的学习与民族振兴的大业联系起来，产下远在志向，为祖国的兴盛而学习和奋斗，后来成为新中国的第一任总理，受到全国人民乃至世界各国人民的爱戴，可见，高尚、远大的理想和明确的奋斗目标对人一生的引领作用有多么巨大！
关于11月27日感恩节的国旗下的讲话
学会感恩亲爱的老师们、同学们:大家好！今天我讲话的题目是《学会感恩》。“感恩”是中华民族的传统美德，“滴水之恩，涌泉相报”“谁言寸草心，报得三春晖”，这是祖先为我们留下的教诲。怀着一颗感恩的心看世界，你才会真正幸福。父母的每一句关心的话语,你是否想到说一声“谢谢”，为了你的安全，为了你的温饱，为了你的成长，他付出的不仅是汗水，更多的是心血，对此，你是否有一颗感恩的心？每当你走进校园时，你会看见高大的树林，美丽的花草，整洁的教室，此时此刻的你是否想到这舒适的学习环境是学校、老师、同学们共同营造的？当我们能够这样幸福的在这样的环境中学习、生活，对此，你是否有一颗感恩的心？同学们，如果你心存感恩，当你因犯错误而受到老师的批评时，你应该虚心接受，因为你知道，老师是真心帮助你；当你每天都听到父母的唠叨时，你应该耐心倾听，因为父母是很爱你的。
关于考试成绩的国旗下的讲话
认清自己，做好准备尊敬的各位老师，亲爱的同学们：这个学期马上就要结束了，想必大家都有同样的感受：开学的情景似乎还在眼前，可我们却在准备期末考试了。请不要问时间都去哪了，我知道你一定明白，时间总是在你不经意间溜走的。站在这里，首先，我想对高一的学弟学妹们说：恭喜你们，艰苦的高中生活你们已经走了三分之一。但是挑战才刚刚开始，高二是高中三年的关键，也是最难把握的一年。高二年级有两大特点：一是教学进度快，一年要完成二年的课程；二是高一的新鲜过了，距离高考尚远，这是最容易玩的疯、走的远的时候，导致很快就进入心理上的迷茫，学业上进的缓慢期，自我约束的松散期，大浪淘沙的筛选期。有调查显示：一半以上的高中学生认为，成绩明显退步的阶段，就是高二，高二的这两大特点是如此的鲜明、突出、同在、对立、不调和，各占矛盾的一个极端，同时起作用，就多少显得残酷而无奈。然现实如此，我们不可能改变规律，认清高二的任务，显得意义十分重大而迫切。因为，高二的这个岔路口，分出的是渐行渐远的两条路，指向的是人生意义上的两个截然相反的的阶段性终端。
关于安全每一天的国旗下的讲话
国旗下的讲话稿安全每一天各位老师、同学们：大家早上好！“安全”这个词对大家并不陌生，像“安全重于泰山”这样的警示更是时常见到。虽然安全十分重要，但在日常生活中有些人却总把安全抛在脑后，其实当他们把安全轻视的时候，危险就在慢慢向他们靠近。远的不说，回想一下在本学期，还记得我们邀请交警叔叔给大家做的安全讲座吧？那些就发生在我们周边的一个个交通事故的片段，你还印象深刻吗？是啊，当你看到一个个鲜活的生命消失于车轮之下，当你发现一阵阵欢声笑语湮没在尖锐的汽笛声中，当你面对那些触目惊心的场景时，能不感到震痛吗？这沉痛的案例发生的原因要么是违规驾驶，但更多的是因为行人没有按交通规则行走，闯红灯或没走斑马线。可见，一次小小的违规背后竟隐藏着巨大无比的杀机
关于爱护公物的国旗下的讲话
国旗下的讲话稿爱护公物亲爱的老师，同学们：大家早上好！今天我要演讲的主题是《爱护公物 从我做起》一说起爱护公物，也许有人会认为这是老生常谈，因为类似“爱护公物光荣，破坏公物可耻”、“爱护公物，人人有责”这样的口号恐怕连幼儿园小朋友也能说上几条。但现实生活中的我们又做得怎么样呢？细心观察就会发现，校园里破坏公物的现象比比皆是：有的同学椅子不好好坐，使得椅子很快就坏了；在走廊和课桌椅上也经常会看见各式各样的涂鸦，短暂的课间时间更是成了“战场”，相互嬉戏间用力关门、踢门随处可见；我们学校的水龙头更换率也在不断的提升，诸如此类的事情还有很多……你们有没有想过，不论是有意还是无意，这些行为都对公物造成了损坏，也给其他同学的学习和生活带来了不必要的麻烦，还会增加学校对公物的维修费用，这可是一笔不小的开支。
关于《天道酬勤》的国旗下的讲话
《天道酬勤》各位老师，各位同学：大家好！今天，我国旗下讲话的题目是《天道酬勤》。当青春的翠绿催醒了温馨的校园，空气中渗透着早春的微凉，校园里到处绽放着青春的笑脸，在这样的一个时刻，我们迎来了一个全新的学期。又是一个新年的开始，又是一个新学期的开始，我们又来到了一个新的起点，迎接新一轮的挑战。俗话说：一年之计在于春。我们在春天里播撒文明、勤奋、乐学、健康、合作的种子，秋天里就会收获明礼诚信、乐学善思、身心健康、团结合作的丰硕成果。播种离不开耕耘，只有辛勤耕耘，我们才能学会求知、学会健体、学会合作、学会做事、学会做人，享受到进步的喜悦，享受到收获的幸福。这个学期对于我们来说，是一个重要的学期，也是一个冲刺的学期，因为高三毕业班的学哥学姐们为了圆自己的梦，即将背水一战。它又是一个奋斗的学期，因为高一、高二的同学们，也将为一个更高的目标而奋斗。

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! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? 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!

关于新型城镇化建设问题的思考的调研报告
二、要清醒认识我市城镇化建设中存在的问题 从1993年以来，我市城镇化建设取得巨大成就，城乡面貌发生了翻天覆地的变化，就是我们这些后来者，每当谈到X市城镇化建设都常常引以为豪。今天，我提出要清醒认识我市城镇化建设中存在的问题，就是要求我们要站在新的起点上，承前启后，继往开来，把X市城镇化建设再次掀起新高潮。 第一，规划起点不高。主要体现在四个方面：一是空间发展格局不到位。在生产、生活、生态空间，地上、地下、地面空间，存量、增量、留白空间等三大系统方面统筹不好。二是规划的前瞻性不够。比如，X市2015—20**年的城市规划，20**年前的建设用地规模根本满足不了实际需求；提出的六组团建设规划，规划修编刚结束，其中火车站物流组团就必须考虑重新规划选址的问题。三是特色不突出。我市城镇化建设给人的感觉是在“摊大饼”，在城市空间利用上、建设上、环境上、配套上研究不够，体现不出自己的特色；我市是民族自治市，但在民族文化研究上研究不深，在城镇化建设上看不出更多的民族文化特色；山水生态是我们的优势，但利用不充分，结合不是很理想。四是政府重视不够。由于我们缺少专业知识，工作方法不到位，与规划部门沟通不多，更提不出好的意见，基本上是由规划单位独立操作。同时，由于受资金影响，请不起一流的规划单位，加之他们深入实地少，对市情、县（市）情了解不多，等等。
