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。

落实河长制，是抓好河湖综合治理、推进生态文明建设的制度保证。河长制在全国推行已经一年多了，实践证明是行之有效的。目前，X已经建立了市县乡村四级河长体系，形成了一套运作机制，开展了一系列工作，取得了一定成效，但相关制度措施还不完善，协调联动的工作格局还没有真正形成，四级河长的作用发挥还有待进一步提升、有的河长仅仅是挂个名，宣传引导、经费保障等方面还不到位。
在全市老旧小区改造工作座谈会上的讲话
城市是当今世界各种要素资源和人类社会活动最集中的地方。人们来到城市，是为了生活；人们居住在城市，是为了生活得更好。当前，我们正积极落实省委“三个五”发展战略，按照“打先锋、站排头”要求，加快建设X城市。在此过程中，我们要坚持新区建设和旧城改造同步推进，一方面建设新区，培育城市新的增长极，加快经济结构调整和发展方式转变步伐；另一方面，加大老旧小区改造工作力度，完善城市功能，提升城市品位和核心竞争力，为广大市民提供良好的生产生活环境，努力实现“双核带动”。

在全区下半年重点工作部署会上的讲话
今年以来，在市委、市政府的坚强领导和关心下，我区坚持中国农谷核心区建设不动摇，紧扣高质量发展要求，聚焦生态农产品加工和农耕文化旅游两大产业，抢抓乡村振兴、农垦改革等多重机遇，扎实推进各项工作，全区经济社会发展呈现出健康发展的良好态势。上半年，出口总额完成X万美元，同比增长X%，增幅全市排名第一;工业用电量同比增长X%，增幅全市排名第三;公共财政预算收入完成X元，同比增长X%，增幅全市排名第三；其它经济指标较好实现双过半任务。
在全镇森林防火和抗旱工作会议上的讲话
一是要按照“先生活、后生产”的原则和“生产服从生活、保苗服从人饮、发电服从灌溉、养殖服从抗旱、工业服从农业”的要求，抓紧做好实施应急供水方案，把保障人畜饮水作为抗旱的首要任务，突出重点，统筹兼顾，千方百计保障镇村生活用水需求。要加强管理和组织调度，高度重视镇村供水工作，加强水源保护和水质监测，对供水工程进行统一管理及维护，组织实施计划用水、节约用水，确保镇村供水安全;采取有力措施，对确实存在困难的地方，要制订供水方案，立即组织送水车辆，发动村组干部和镇机关、中心（所）干部，按照“先保人、后保畜”的原则组织送水，切实解决农村人畜饮水困难。同时，积极发动和组织群众寻找水源，实施应急水源工程建设，开展抗灾自救。二是积极发动群众做好生产自救。
在全市工业和信息化工作会议上的讲话

在市国资系统调研座谈会上的讲话
思想观念的变革，是一个地区、一项事业兴旺发达的重要决定因素。观念不改变，就难以适应不断发展变化的形势。解放思想永无止境，今天思想解放，不代表明天就思想解放，必须以永不僵化、永不满足、永不懈怠的进取精神大力推进思想解放。从历史上看，东北地区特别是X作为国家重要的工业基地，为支撑新中国工业架构体系作出了突出贡献，有力助推了我国社会主义现代化建设和改革开放进程。
