国旗下讲话稿：长跑锻炼的好处
老师们，同学们，大家好：今天国旗下讲话的题目是——长跑锻炼的好处。寒冷冬季，北风萧瑟，清冷街头，稀疏人迹，抬头看空荡荡的枝头，一股莫名的伤感由然而生，枯黄的干叶在寒风中飞舞落下，似翩翩的舞者，只留下孤单的枝头在冷清的季节打颤发抖。在寒冷的冬季，面对一次次的冬季长跑锻炼，你退缩了，你愉懒了，你逃避了。孰不知你逃开的，不仅是跑步训练，还有毅力的磨练，体格的锻炼。让我们来听听健身长跑的好处吧!有关专家表示，长跑可提高呼吸系统和心血管系统机能，科学实践证实，较长时间有节奏的深长呼吸，能使人体呼吸大量的氧气，可以抑制人体癌细胞的生长和繁殖。其次长跑锻炼可以提高了心脏工作能力。
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。
《规则之上的自由》班会说课稿
1、 通过活动的开展与交流，让学生明白到底为何自由要有规则来局限。2、 通过活动的参与，学生能够懂得什么是真正的自由。3、 逐步养成即懂规则又懂自由的好习惯（性格、意识），树立正确的人生观、价值观。三、说活动准备为了使本课的活动目标顺利完成，课前需要做一定的活动准备。教师准备：搜集大量的和自由有关的资料，视频、图片、案例等。学生准备：1、课前搜集有关自由的故事；2、排演情景剧、诗朗诵、小品等。四、说活动重难点重点：让学生理解（感受）到规则之上的自由的重要性。难点：让学生学以致用，自由观念深入人心。五、说活动方法根据本节课的具体内容，结合小学生具有的心理特点，我采用了讲述法、课堂讨论法、学生互动交流、表演节目、举例子等方法。学生主要采用“自主、合作、探究”的探究方法，充分地调动小学生参与活动的积极性，达到预期的教育目的。
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。

温故知新 1.离散型随机变量的定义可能取值为有限个或可以一一列举的随机变量,我们称为离散型随机变量.通常用大写英文字母表示随机变量,例如X,Y,Z;用小写英文字母表示随机变量的取值,例如x,y,z.随机变量的特点: 试验之前可以判断其可能出现的所有值，在试验之前不可能确定取何值；可以用数字表示2、随机变量的分类①离散型随机变量:X的取值可一、一列出；②连续型随机变量:X可以取某个区间内的一切值随机变量将随机事件的结果数量化．3、古典概型:①试验中所有可能出现的基本事件只有有限个；②每个基本事件出现的可能性相等。二、探究新知探究1.抛掷一枚骰子,所得的点数X有哪些值？取每个值的概率是多少？ 因为X取值范围是{1，2，3，4，5，6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention，the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste.

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

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!

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。

全力确保稳增长。当前经济发展形势十分复杂，各种困难问题叠加，稳增长的压力很大。我区正处在转型发展的关键期、过渡期，经济发展基础不厚实、支撑不牢固，面临的困难更多。总的看，上半年经济工作有喜有忧。部分指标超过时间进度，但有些指标落后时间进度，生产总值、规模以上工业增加值、固定资产投资等指标无论总量还是增幅都与先进地区有较大差距。
