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. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.

XX中学2023-2024学年班主任工作总结
树立班主任学生观：其一班主任应该感谢问题学生，是因为学生成长中的种种问题表现，才给了班主任实践成长的机会；其二班主任必须善待问题学生，初中学生本来就是正在逐渐成熟过程中的没有懂事的小孩，换言之，小孩总是在不断试误过程中，得到教训，接受道理，消除童蒙，逐步养正的。因此班主任必须有足够的宽容、耐心、爱心，用心呵护真情浇灌，迟开的花朵更美丽。三、锻炼了班主任的工作技能班主任工作是个性化工作，班主任工作很繁琐，特别是年轻班主任，一方面要从事繁重的教学工作，另一方面又要承担繁琐的班级管理工作，千头万绪，不知从何下手，为了使年轻班主任尽快掌握班集体形成规律，有效的开展班集体建设，我们制定了20条班主任工作规范，让年轻班主任更快的适应班级管理工作。工作规范具有很强的指向性、指导性和可操作性，班主任可以少走弯路，切实提高班集体建设的实效性，加快年轻班主任的成长历程。

问题1. 用一个大写的英文字母或一个阿拉伯数字给教室里的一个座位编号，总共能编出多少种不同的号码？因为英文字母共有26个，阿拉伯数字共有10个，所以总共可以编出26+10=36种不同的号码.问题2.你能说说这个问题的特征吗？上述计数过程的基本环节是：（1）确定分类标准，根据问题条件分为字母号码和数字号码两类；（2）分别计算各类号码的个数；（3）各类号码的个数相加，得出所有号码的个数.你能举出一些生活中类似的例子吗？一般地，有如下分类加法计数原理：完成一件事，有两类办法. 在第1类办法中有m种不同的方法，在第2类方法中有n种不同的方法，则完成这件事共有:N= m+n种不同的方法.二、典例解析例1.在填写高考志愿时，一名高中毕业生了解到，A,B两所大学各有一些自己感兴趣的强项专业，如表，

当A,C颜色相同时,先染P有4种方法,再染A,C有3种方法,然后染B有2种方法,最后染D也有2种方法.根据分步乘法计数原理知,共有4×3×2×2=48(种)方法;当A,C颜色不相同时,先染P有4种方法,再染A有3种方法,然后染C有2种方法,最后染B,D都有1种方法.根据分步乘法计数原理知,共有4×3×2×1×1=24(种)方法.综上,共有48+24=72(种)方法.故选B.答案:B5.某艺术小组有9人,每人至少会钢琴和小号中的一种乐器,其中7人会钢琴,3人会小号,从中选出会钢琴与会小号的各1人,有多少种不同的选法?解:由题意可知,在艺术小组9人中,有且仅有1人既会钢琴又会小号(把该人记为甲),只会钢琴的有6人,只会小号的有2人.把从中选出会钢琴与会小号各1人的方法分为两类.第1类,甲入选,另1人只需从其他8人中任选1人,故这类选法共8种;第2类,甲不入选,则会钢琴的只能从6个只会钢琴的人中选出,有6种不同的选法,会小号的也只能从只会小号的2人中选出,有2种不同的选法,所以这类选法共有6×2=12(种).因此共有8+12=20(种)不同的选法.

XX年秋季学期第一次月考国旗下讲话稿：备战月考，你我同行
尊敬的各位领导、各位老师、亲爱的同学们：大家早上好！你会用什么词来形容秋天呢？金灿灿、秋高气爽、秋风瑟瑟，对！这些就是秋天独有的景色。秋天还是收获的季节，春华秋实，有种子，有积累，有沉淀，才能有收获。学习、人生都如此。不管你是初来乍到的新生，还是在这里已经学习了一两年的学哥学姐，都会在10月8日迎来学部的第一次月考。一听考试，你们现在是不是已经感受到了秋风瑟瑟啊？其实，这是很正常的心理反应，老师今天就想说说考试这个事。首先，面对考试的态度要乐观。每个人是独特的，学习的能力是不同的，学习的基础也有差异，自然学习就有快有慢。在学习时，既需要有好的竞争氛围，又不能一味的去和别人比较，为什么人家背一会儿就会背了，我怎么背不会？为什么人家一听课就会做题，正确率还很高，我怎么就不行？一旦产生了这些消极的想法，就会阻碍学习。我们学习是为了将来更好的生活、是为了获得学习能力。因此，找准自己的位置，向榜样学习，认真做好自己，乐观面对考试，就显得特别重要。只要努力了，就无愧于心，就能让家长放心，就能回馈老师，加油吧，孩子们！
XX年秋季学期第一次月考国旗下讲话稿：珍惜每一次考试
今天是9月26号，再过三天我们就要进行本学期的第一次考试了。在此之前，我们已经在考场上身经百战，并且也可以想象的是，在接下来的求学日子里，我们还会经历大大小小各种各样的考试。这样看来，好像这一次被冠之以“月考”之名的考试并不是太重要，或者说在百校联考、广州一模、甚至到最后的高考对比之下，显得小巫见大巫。你们真的会这样想吗？抱着这样想法的同学，你们可能会在每天的浑浑噩噩和麻木中不知不觉地掉队。在我看来，每一个同学都应该好好珍惜人生中遇到的每一次“考试”。放在高中来看，大到每次的联考统考，小到周测和课堂测验。我们首先要明白考试的存在和意义是什么：考试是为了让你更清楚地明白自己在上一个学习阶段中的得与失，从而更从容地调整自己往下一个阶段出发，不断地推进，变成更好的自己。每一次的考试都能够帮助我们查漏补缺，同时也能肯定自我的付出和努力，这是我们珍惜考试的意义。另外，还有一个很现实的理由：有同学会说：“高考离我还很远，我只在乎高三的几次大考。”其实我们心里都清楚，高三的我们还会有几次考试呢？对于高中学习想要在最后的几次考试中就把自己的能力证明出来，这显然是不现实的。荀子曰：“不积跬步无以至千里，不积小流无以成江海。”
XX年秋季新学期国旗下讲话稿：八月，放飞理想，共同成长
XX年秋季新学期国旗下讲话演讲稿：八月，放飞理想，共同成长尊敬的老师、亲爱的同学们:大家早上好！今天我国旗下演讲的题目是《八月，放飞理想，共同成长》带着对暑假生活的美好记忆，怀着对新学期新生活的美好向往，我们又回到了宁静的校园，欢聚一堂，并聚集在庄严的国旗下，此时，我们的心情是高兴的。对我们可爱的同学来说，今天是我们成长历程中又一个全新的起点；对我们可敬的老师来说，今天是又一段辉煌事业的开始；对我们可亲的学校来说，它所引领的，必将是二高中灿烂的每一天！秋天是收获的季节，秋天从来都属于辛勤耕耘的人们。在刚刚过去的一学年里，全校师生齐心协力、辛勤工作、努力拼搏，学校在各个方面都得到稳步的发展。亲爱的同学们，成绩已经成为过去，面对新学年新的任务、新的挑战，我们要更加努力。
XX年秋学期第八周国旗下讲话稿：在书香中快乐成长
各位老师同学们早上好!今天我国旗下讲话的题目是《在书香中快乐成长》.说到书,我们很自然地想起了我们在学校学习的任务——读书.是的,课堂上,我们在老师的带领下,努力学习,认真读书.我们读的是课本,读的是语文书、数学书、科学书等等.在书中,在一句句、一篇篇奇妙的文字中,我们汲取着人类智慧的结晶,我们的大脑接受着一次次知识的洗礼,我们感受着成长的快乐.其实,读好课内的书,只是为我们读更多的课外书打下良好的基础.当我们迎着朝阳,背上心爱的小书包走进学校的大门,我们就开始拥有读书的本领.同学们,当我们学习了汉语拼音,我们开始尝试用拼音拼读课外书,看着美丽的图画,还能拼读出图画下的文字,你就会骄傲地大声地把有文字的故事读懂,故事的喜怒哀乐就会带给你无穷的快乐

不做“小马虎”
一、说教材分析《不做“小马虎”》是统编教材一年级下册《道德与法治》第一单元《我的好习惯》中的第4课内容。教材中有两个部分：生活中的小马虎和怎样才能不马虎。其中有一个关于马虎原因的探讨——小马虎找原因，和克服马虎方法的指导，教材辅助部分是两个绘本故事：小马虎添麻烦和马虎危害大。教材从儿童的现实生活出发，呈现马虎的普遍现实，指明马虎带来的麻烦和危害，分析其形成的原因，寻找克服马虎的办法。有情感的体验，认知的唤醒，更有行为的指导。本课的编写是基于课程标准“负责任，有爱心地生活”中的第一条——“做事认真负责，有始有终，不拖拉”而编写的，意在培养学生的耐心与责任心，在生活和学习中养成认真细致，不马虎的好习惯。二、说学情分析 通过对一年级学生、家长、老师做了调查和访谈，发现以下情况：在学习中，经常因马虎抄错题、算错题、漏做题；会忘记带学习用品，忘交作业等等。在生活中，也常因马虎没听清事情，做错事、忘记事、耽误事。对于马虎带来的后果没有直观的认识，既没有克服马虎的办法，更没有养成做事细致不马虎的习惯和意识。
XX年全国科普日国旗下讲话
老师们，同学们：大家好!本周的教育主题是“我们从小学创造”。回顾人类文明历史，可以发现我们人类刚来到这个世界的时候几乎是一无所有，可是今天，人类却在地球上建立了如此辉煌的文明，成为地球当之无愧的主人。原因是什么呢?那就是一项又一项的科学发明和创造，推动了社会的进步，人类上天入地不再是美好理想，呼风唤雨不再是痴心妄想。作为新一代少先队员，我们有创造人类新文明的责任。我校“保护母亲河”小记者团和“寻访创新”小记者团的队员们勤于实践，勇于创新。他们是同学们的优秀代表，也是大家学习的榜样。以他们为主体的梅乡小虎队被江苏省文明办、团省委等联合表彰为优秀团队。领奖期间，我认识了两位令人敬佩的优秀少年。从他们的身上，看到了我们的不足，主要是创新含金量不够。一位是扬州的李沐同学，一位是南通的季烨剑同学。李沐同学是扬州市实验小学四年级学生，他4岁开始动手实验，7岁申请国家专利，目前他才10岁已拥有3项国家专利权，发表了创新发明类文章5篇，获得了第三届“中国青少年科技创新奖”。六岁的李沐面对可口椰子汁、可乐却无法下手，他拉不开那些易拉罐，因为拉环太小。于是他在多次实验后，在小环上加了一个钥匙圈，伸进手指，一拉就开。这就是他的第一个专利，点燃了他不断创新的火花。
