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!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2.

第十周国旗下讲话稿：有梦想，更要有行动
尊敬的老师，亲爱的同学：早上好！今天，我演讲的题目是《有梦想，更要有行动》。人不能没有梦想，梦想是美好的，但如果梦想，不付诸现实，都只能是一个美好的幻影，梦想的实现需要我们付出很多努力，艰辛。古语云：“天行健，君子以自强不息”，它告诉我们人要有一种积极进取，永不放弃的精神，中职学习生活中同学们可能会面临一些如学习竞争，纪律严格，知识更新，能力发展等新问题。会产生一些如生活环境，师生磨合，期望与现实的落差等新的困惑。但是希望同学们不论遇到多么痛苦的挫折，不论现实和理想有多么大的距离，永远不要放弃和后悔自己的选择，不要让自己的美好理想落空。

人教版高中语文《寡人之于国也》教案
二、孟子的仁政思想1．民本思想。孟子说：“民为贵，社稷次之，君为轻。是故得乎丘民而为天子，得乎天子为诸侯，得乎诸侯为大夫。”（《孟子·尽心下》）得到百姓拥护的人才能成为天子，得到天子欢心的人可以成为诸侯，得到诸侯欢心的人可以成为大夫，可见“民为贵”的道理。孟子在尖锐复杂的阶级斗争中看到人民的力量，认为社会安定的前提在于百姓的安居乐业，这一点在当时也是有积极意义的。2．邦国的主权在民。孟子与梁惠王谈话，梁惠王问：“天下恶乎定？”孟子回答：“定于一。”梁惠王问：“孰能一之？”孟子回答：“不嗜杀人者能一之。”梁惠王问：“孰能与之？”孟子回答：“天下莫不与也。”（《孟子·梁惠王上》）意思是说，如果一个君王不嗜杀戮，那么，天下没有不愿意把政权交给这个君王的人。万章问孟子：“尧以天下与舜，有诸？”孟子说：“否；天子不能以天下与人。”万章问：“然则舜有天下也，孰与之？”孟子说：“天与之。”

2．避免使用过多的描写手法，避免过多地使用形容词，特别是华丽的辞藻，尽量采用直截了当的叙述和生动鲜明的对话，因此，句子简短，语汇准确生动。在塑造桑地亚哥这一形象时，他的笔力主要集中在真实而生动地再现老人与鲨鱼搏斗的场景上。鲨鱼的来势凶猛，老人的沉着迎战，机敏矫捷，都写得生动逼真。如写鲨鱼出现的情形，“当一大股暗黑色的血沉在一英里深的海里然后又散开的时候，它就从下面水深的地方窜上来。它游得那么快，什么也不放在眼里，一冲出蓝色的水面就涌现在太阳光下。”这段描写没有一个比喻句和形容词，但鲨鱼的凶猛、快捷，形势的紧迫却立刻展示在读者面前，清新洗练的叙述文字和反复锤炼的日常用语，使人读来有身临其境之感。文中对大海的描写粗犷简洁，犹如一幅水墨山水画，读来令人心旷神怡，美不胜收。
国旗下讲话：爱护校园环境卫生
老师们、同学们：早上好，我今天讲话的题目是《爱护校园环境卫生》。学校的卫生环境，是学校精神文明建设的窗口，也是我们全体师生素质高低的综合反映。由于有些同学还存在不良的卫生习惯，经常给校园文明带来不良影响。春天是呼吸道传染病的高发期，搞好我们的校园环境尤为重要。然而在我们的校园里，常常会看到一些不和谐的音符。比如：投不中的垃圾被丢弃在垃圾桶外，校园操场上、花坛里、草地上、角落里丢弃着食品包装，楼梯上不时看见纸屑和果壳，食堂里的饭菜遗留在餐桌上，教室里的垃圾熟视无睹，雪白的墙壁上被鞋印玷污……因为卫生工作关系到每一个人，所以请大家在日常工作、学习、生活中积极主动做好卫生工作，保持良好的正确的卫生习惯，促进健康成长。
第十六周国旗下讲话稿：勤奋成就人生
尊敬的老师,亲爱的同学们,大家上午好；今天我演讲的题目是《勤奋成就人生》中国有句俗话，叫做“一勤天下无难事”。唐代大文学豪韩愈就曾说过：“业精于勤，荒于嬉。”也就是说，学业方面的精深造诣于勤奋好学，唯有勤奋者，才能在无边的知识海洋里猎取到真正的智慧。数学家华罗庚说：“勤能补拙是良训，一分辛劳一分才”；科学家爱迪生说：“巨大的成就，出于长期的勤奋”。这就告诉我们，勤奋才能成就人生。古往今来，多少名人雅士都是由于勤奋才成就了自己的伟大人生。孔子曾说自己勤于读书，以至发愤忘食，乐以忘忧。战国时期的苏秦正是由于悬梁刺股，勤奋读书，才终挂七国帅印。马克思写《资本论》，辛勤劳作，艰苦奋斗了四十年，阅读了数量惊人的书籍和刊物，做过一千五百种以上的笔记；我国数学家陈景润在攀登数学高峰的道路上，翻阅了国内外上千本有关资料，通宵达旦的看书学习，最终取得了震惊世界的伟大成就!而我们身边的同学也正是通过勤奋学习，才获得优异的成绩。可见，古往今来，任何一项成就的取得，都是和勤奋分不开的。一分耕耘一分收获，只有勤奋，才是扣开成功人生的敲门砖。
第五周国旗下讲话稿：用合作铸就精彩人生
各位老师，同学们：上午好！今天，我国旗下讲话的题目是：用合作铸就精彩人生。一个人的力量很有限，但是一群人的力量是无限的。《淮南子》有云：用众人之力，则无往而不胜也。这里的众人之力，不单单指的是力量，更是一种能力。就像一位哲人所说的：你手上有一颗苹果，我手上也有一颗苹果，两颗苹果交换后每个人还是一颗苹果；你有一种能力，我也有一种能力，两种能力交换后就不再是一种能力了。无论是“让学引思”课堂教学改革还是我们学校正在推行的“引学讲达”常态课堂实践，其核心就在于合作学习。一人能力有限，多人却各有所长，取彼之长补己之短，汇集大家的智慧于一处，这样的小组和团队必定所向披靡。合作才能共赢，团结更有力量。课堂上，老师通过小组合作、探究的方式带领大家共同学习，共同提高；校园里，丰富多彩的社团活动处处彰显着“合作、共赢”的思想。合作是我们走向社会、走向未来，成人成才必备的核心素养。合作有利于班级凝聚力的形成。凝聚力是一个集体的战斗力的重要标志。一个缺乏合作的集体，往往组织松散，矛盾众多，成员勾心斗角，互不服气，互不信任，认为班里的一切与自己无关，更谈不上有什么战斗力，这就是缺乏集体凝聚力的表现。反之，同学们就会为了班级目标一起努力，逐渐形成团结、合作的班级文化。
世界环境日国旗下讲话稿
各位老师、各位同学：大家好!21世纪可谓挑战与机遇同在，希望与困难并存。生活在给我们带来许多美好憧憬的同时，也给我们带来了许多难题。其中首要的就是环境问题。环境问题是由于人类不合理地开发与利用自然所造成的。随着世界环境问题的日益严重，我们赖以生存的地球引起了世人普遍的的关注与讨论。1972年6月5日，人类环境会议在瑞典首都斯德哥尔摩召开，会议通过了《人类环境宣言》;同年10月，第27届联合国大会通过决议，将以后每年的6月5日定为世界环境日。现在我们又迎来了世界环境日。今年的主题为“你的星球需要你，联合起来应对气候变化”，我国确定的主题为“减少污染——行动起来”。是的，我们的地球母亲已经承受了太多的苦难。早在1996年联合国环境署就曾发出警告：南极臭氧空洞正逐步增大，地面紫外线辐射增强，皮肤癌发病率上升;亿人口生活在混浊的空气里;12亿人口缺水;每年地表土壤流失200亿吨;森林以每年45万公顷的速度消失。现在全球每年有600万公顷的土地沦为沙漠，平均每小时就有一个物种在灭绝。温室效应使海平面不断升高，世界上众多城市、岛屿和大量土地，用不了多久将被海水吞没。
爱护环境国旗下讲话稿
在学生需要以爱护环境为题进行国旗下的讲话时，需要准备好演讲稿，那么都有哪些好的演讲稿呢？下面是小编分享给大家的爱护环境国旗下讲话稿，希望对大家有帮助。爱护环境国旗下讲话稿篇1 尊敬的老师，亲爱的同学们：大家好!今天是6月5日—世界环保日。今天我要演讲的题目是《保护环境卫生，人人有责》。在我们的日常生活中，生活环境是十分重要的，但人们常常不重视这一方面。使清澈见底的小溪变成了肮脏的水沟;郁郁葱葱的大森林变成了落光头发的老爷爷;鸟语花香的村庄变成了山洪爆发的地方……这一切都是由人类的一举一动所造成的。前几日，我到广场上骑自行车，发现不远处的草坪中有许多的白色垃圾，真是不计其数!可见我们的环保意识还不够强。说小一点儿，影响该地区的形象;说大一点儿，这是影响我们国家的形象啊!作为一名少先队员，作为一名小学生，我们也应该保护环境，从我做起，从小事做起，从力所能及的事情做起。当别人随手扔下垃圾的时候，你会去捡起;当别人践踏草坪的时候，你会去阻止;当别人在破坏树木的时候，你会去教育……
