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!

二、动物的游戏（库宝善）人类社会越来越现代化，新科学技术日新月异，令人目不暇接，称之到了“知识爆炸”的时代也毫不为过。由此而来的是生活的快节奏，学习和工作的竞争也越来越激烈。这种竞争一直波及到了儿童，加之中国几千年来形成的望子成龙的传统观念，使作父母的把一切希望都寄托在孩子身上，实现自己未能实现的理想。祖孙三代4、2、1的局面，使12只眼睛都盯在了孩子身上，真是走路怕摔着，吃饭怕噎着，干活怕累着，要星星不敢摘月亮，要吃什么跑遍全城也要买来。这种过分保护、溺爱及过早地灌输知识会得到什么结果呢？乐观者说孩子越来越聪明，越来越早熟，将来能更好适应现代化的要求；悲观者则认为豆芽菜式的孩子将来经不起风浪，小皇帝太多了很难凝聚成统一力量，将来谁去当兵，谁去干那些艰苦创业性工作……。对孩子本身来说，是幸福还是……在此不想多发议论，还是让我们来看看动物世界的孩子们吧，也许会得到某种启迪。
高效课堂教学培训个人心得体会八篇
一是教师讲得多，学生学得少。 学生是课堂教学的主体，这是提教师们经常用说到的课改理念，但在实际的教学中确并没有有效贯彻，许多教师在上课时还是“满堂灌”，一讲到底。要发挥学生的主体作用，就必须让学生参与到学习中来自主的学习，就必须保证学生有学习思考的时间和空间，可这种方式课堂基本被教师霸占，学和理被动的接受，要本就不能主动的学习。洋思中学的实践证明，课本上的知识有百分之八十是学生通过自学能学会的，根本就不需要教师多讲，并对课堂教学作出了规定，一节课教师纯讲时间不超过10分钟。我校也曾要求教师不能满堂讲，把讲授时间控制在25分钟，提倡引导学生自主学习，但效果不明显。要发挥学生学习的主体作用，就必须从引导学生预习、鼓励课堂展示、保证当堂训练时间和进行课堂检测这几个环节上多下功夫。在课堂要做到“三讲三不讲”，“三讲”即：讲核心的问题，讲学生思路和方法，讲知识缺陷和易混易错知识，“三不讲”即：学生会了的不讲，学生能自学会的不讲，讲了学生也不会的不讲。
在疫情防控最新进展情况通报和部署会上的讲话
严格防控疫情。一是严防疫情反弹外溢。我们对XX镇封控区、管控区及重点暴露场所进行严格管理，连续开展“扫楼敲门”行动，确保相关人员“足不出户”“足不出小区”，防止疫情在社区出现反弹。全市倡导非必要不离XX、非必要不出省。二是严防疫情倒灌。这是为了应对当前全国疫情发展出现的形势变化，我们正在加大力度推进的重要工作。重点是像排查出此次XX疫情首两例病例一样，迅速管控排查出涉疫地区来XX返XX人员，以免新的疫情发生。请广大市民朋友密切留意疫情发展动态，如非必要近期不要前往中高风险地区以及疫情发生地区；
在市防汛抗旱指挥部成员（扩大）视频会议结束后的讲话.docx
要立足于防大汛、抗大旱、抢大险、救大灾，从实际要求出发，抓紧补充储备防汛抗旱抢险物资，做好落实抢险方案和后勤保障。目前已进入汛期，各单位要抓紧查漏补缺，特别是重点险工险段必须将抢险物资提前运抵现场，一旦发生险情，确保“调得出、用得上”。
在全区防汛抗旱和地质灾害防治工作会议上的讲话
第一，强化底线意识，科学及时预测预警。镇、街道、区级各部门要高度重视防汛抗旱和地质灾害防治，切实增强工作的责任感和紧迫感，把措施落实到具体工作中，做到科学救灾、科学避险。要科学及时有序地开展预测预警，请区水利局及时和市气象局、市防震减灾局做好相关具体工作的对接。要做好防大灾的早准备、细准备、大准备，从省、市通报的情况看，今年攀枝花汛期降水量接近常年、降水偏多，降雨量在局部区域比较集中且空间分布不均，存在旱涝交替，发生极端天气事件风险较高，气候年景较差，而且局部区域发生泥石流、山洪、地质滑坡灾害等可能性加大，镇、街道、区级各部门必须克服侥幸心理、麻痹心理，防范于未然。
全区都市工业研讨会上的工作总结讲话发言报告
一个城市的长远可持续发展，离不开实体经济的支撑。发展好工业实体经济，要求全区上下聚焦“智能化”、“高精尖”先进制造业，加快发展符合产业定位的产业实体项目，引进培育研发设计、检验检测、销售服务等生产性服务业。工业发展事关我区经济底蕴和城市竞争力，坚定不移地狠抓实体经济是区委、区政府长期的、重要的战略性布局，各部门单位要统一思想，各位企业家朋友要坚定信心，困难必须要克服，工业必须要高标准、高质量发展。经济发展已进入新常态，靠资源、土地推动发展的要素驱动模式正丧失竞争优势，与之对应的是创新驱动成为发展的主要动力，正如房地产行业更加强调地段和位置一样，城市软环境将逐步成为产业发展的核心竞争力。都市工业就是在有限空间内提高工业质效的有效途径，经济新常态为X带来了解决问题的机遇和转型发展的潜力，X都市工业有优势，有基础，有前景。

在全市招商引资工作视频调度汇报会上的讲话

在“六员进校园、合力保平安”工作推进会上的讲话发言
教育是个大系统，全市现有各级各类教育学校X多所，在校生X多万人，教职工X多万人，师生人数占全市总人口的近X%，这对做好学校的安全工作提出了严峻的挑战。近年来，我们在市委、市政府的正确领导下和各兄弟局委的大力支持下，针对X教育体量大、差异大、地理环境、社会环境、文化环境复杂的特点，认真贯彻落实上级关于安全工作的有关要求，从讲政治、促发展、保稳定的高度，凝心聚力，扎实工作，精准施策，全市中小学幼儿园安全工作取得了明显成效：广大师生安全意识明显增强、安全基础设施不断改善、隐患排查机制深入落实、安全责任体系初步建立，学校安全工作的整体水平得到了一定提升。但是与市委、市政府的要求相比，与建设国家中心城市的要求相比，X市教育系统安全工作还存在着城乡发展不平衡、硬件设施不先进等问题。对安全工作重视不够、安保设施不全、安全教育不落实、家校沟通不畅等现象在一些学校仍然存在。
