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

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. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

国旗下的讲话：远离危险保安全
同学们： 今天，我讲的题目是：远离危险保安全。（一）进入五月份后，天气逐渐转热，擅自到江河、水库、池塘游泳的学生溺水身亡事故进入易发期、高发期、危险期。为预防学生溺水事故的发生，教育部于XX年就发布文件要求学生做到“六不”1.不私自下水游泳；2.不擅自与他人结伴游泳；3.不在无家长或老师带领的情况下游泳；4.不到无安全设施、无救援人员的水域游泳；5.不到不熟悉的水域游泳；6.不熟悉水性的学生不擅自下水施救。以上“六不”要求，我们XX年、XX年两次通过致家长的一封信的方式告知家长，有的年级还通过家长会的方式进行了强调。通过学校和家长的共同教育，我校学生遵守“六不”要求，没有发生溺水身亡事故，今天，我再次重申教育部的“六不”要求，就是为了避免此类悲剧的发生。

关于中小学教师职业道德规范学习心得体会八篇
1、修师德，从勤于育人做起 当您漫步在校园时，您便会发现在这块实验田里，每一天都有一串动人的故事在编织着。在教书育人中我们要努力做到“三心俱到”，即“爱心、耐心、细心”，无论在生活上还是在学习上，时时刻刻关爱学生，特别是对那些特困生，更是“特别的爱给特别的你”，切忌易怒易暴，言行过激，对学生有耐心，对学生细微之处的好的改变也要善于发现，并且多加鼓励，培养学生健康的人格，树立学生学习的自信心，注重培养他们的学习兴趣。 2、修师德，从小小微笑做起 热爱学生，是师德的永恒话题。如何体现教师的爱，如何让学生接受教师的爱，我认为，最简单、最容量做到的、最好的效果是从微笑面对学生做起。
XX-XX学年度上学期运动会动员国旗下讲话稿：驱赶秋日的寒意，点燃运动的热情
尊敬的老师们、亲爱的同学们，大家早上好，我是高二（3）班的童xx，今天我演讲的题目是“驱赶秋日的寒意，点燃运动的热情”。为了丰富校园文化生活，展示学校教育成果，促进学生德智体美劳全面发展，本周我校将举行秋季运动会。这将是一次展示力与美的盛会，也将是一次体魄与耐力的比拼。运动会是检验学校水平高低的一个标志，也是各个班级、每位同学展示风采的一个舞台。运动会是一个竞技场，优胜劣汰，容不得半点虚假。同一起跑线上，你付出多少汗水，就会有多少回报。没有顽强的拼搏，不会有优异的成果；没有坚定的信心，跑道上不会有你亮丽的身影。体育舞台是人生舞台的一个缩影，鲜花和掌声是献给脚踏实地、顽强拼搏、不畏艰难的人。“重在参与”展现着我们的积极心态，“为班争光”蕴含着我们的集体主义情怀，赛场上人人都是胜利者，结果并不重要智力与体力才是我们追求的目标。运动会不仅可以检验我们的运动水平和班级凝聚力，还可以充分展示我校同学朝气蓬勃的精神面貌。运动会不仅比运动水平运动精神与全校师生对德、智、体全面发展的教育方针的全面理解。
北师大版初中数学九年级下册三角函数的有关计算说课稿
设计意图：最后是当堂训练，目标检测，这一环节要尽量让学生独立完成，使训练高效，在学生训练时教师要巡回辅导，重点关注课堂表现不太突出的学生，由于本课时内容多，训练贯穿课堂始终，加上不能使用计算器，因此课堂节奏难于加快，所以当堂训练的时间预估不足。四、教学思考1．教材是素材，本节课对教材进行了全新的处理和大胆的取舍，力求创设符合学生实际的问题情境，让学生经历从实际问题中抽象出锐角三角函数模型的过程，发展了学生的应用意识及分析问题解决问题的能力，培养了学生的数学建模能力及转化的思维方法。2．充分相信学生并为学生提供展示自己的机会，课堂上要把激发学生学习热情和获得学习能力放在教学首位，通过运用各种启发、激励的语言，以及小组交流、演板等形式，帮助学生形成积极主动的求知态度。
北师大初中数学七年级上册统计图的选择说课稿
四、教学过程分析为有序、有效地进行教学，本节课我主要安排了以下教学环节：（一）复习导入主要复习一下三种统计图，为接下来介绍三种统计图的特点及根据实际问题选取适当的统计图做好知识准备。（二）问题探究选取课本上“小华对1992～2002年同学家中有无电视机及近一年来同学在家看电视的情况”的3个调查项目，进而设计3个探究问题从而加深学生对每一种统计图的进一步认识，至此用自己的语言总结出每一种统计图的特点。（三）实践练兵这一环节通过2个实际问题的设计，通过学生对问题的分析、讨论，使学生认识到适当选取统计图有助于帮助人们去更快速、更准确地获取信息。（四）课堂小结总结这一节课所学的重点知识，这部分主要是让学生自己去总结，看看这节课自己有哪些收获。（五）作业布置进一步巩固本节课所学的知识，达到教学效果。以上就是我对这节课的见解，不足之处还望批评和指正。
北师大版初中七年级数学下册利用轴对称进行设计说课稿
一、教材分析轴对称是现实生活中广泛存在的一种现象，本章内容定位于生活中轴对称现象的分析，全章内容按照“直观认识——探索性质——简单图形——图案设计”这一主线展开，而这节课作为全章的最后一节，主要作用是将本章内容进行回顾和深化，使学生通过折叠、剪纸等一系列活动对生活中的轴对称现象由“直观感受”逐渐过渡到从“数学的角度去理解”，最后通过图案设计再将“数学运用到生活中”。轴对称是我们探索一些图形的性质,认识、描述图形形状和位置关系的重要手段之一。在后面的学习中，还将涉及用坐标的方法对轴对称刻画，这将进一步深化我们对轴对称的认识，也为“空间与图形”后继内容的学习打下基础。二、学情分析学生之前已经认识了轴对称现象，通过扎纸探索了轴对称的性质，并在对简单的轴对称图形的认识过程中加深了对轴对称的理解，但是对生活中的轴对称现象仍然以“直观感受”为主。
幼儿园防溺水安全教育教案
1、镇定第一。落水后应保持镇定，胡乱举手或挣扎反会使身体下沉、呛水而淹溺。2、仰泳露鼻。可采取头向后仰、面部向上的仰泳法，使口鼻露出水面进行呼吸。3、深吸浅呼。吸气要深，呼气要浅。4、减轻自重。及时甩掉鞋子和口袋里的重物，但不要脱掉衣服，因为它会产生一定的浮力，对你有很大帮助。5、观察周围。假如周围有木板，应抓住，借用木板的浮力使自己的身体尽量往上浮。6、缓解“抽筋”。若肌肉痉挛（“抽筋”），用手握住痉挛肢体的远端，做反复屈伸运动。7、保存体力。会游泳者在落水自救的过程中，应注意防止“抽筋”，并保存体力。8、配合施救。如果有人跳水相救，千万不可死死抱住救助者不放，而应尽量放松，配合救助者把你带到岸边。

防踩踏安全教育主题班会教案
三、教学方式：讲述及案例分析四、教学过程(一)拥挤踩踏事故处理方式在公共场所发生人群拥挤踩踏事件是非常危险的，而那些空间有限，人群又相对集中的场所，例如球场、商场、狭窄的街道、室内通道或楼梯、影院等都隐藏着潜在的危险，当身处这样的环境中时，一定要提高安全防范意识。同时，在行进的人群中，如果前面有人摔倒，而后面不知情的人若继续向前行进的话，那么人群中极易出现像“多米诺骨牌”一样连锁倒地的拥挤踩踏现象。为此，专家分析认为，在人多拥挤的地方发生踩踏事故的原因有多种，一般来讲，当人群因恐慌、愤怒、兴奋而情绪激动失去来自理智时，危险往往容易产生。此时，如果你正好置身在这样的环境中，就非常有可能受到伤害。在一些现实的案例中，许多伤亡者都是在刚刚意识到危险时就被拥挤的人群踩在脚下，因此如何判别危险；怎样离开危险境地；如何在险境中进行自我保护，就显得非常重要。当发现前方有人突然摔倒后，旁边的人一定要大声呼喊，尽快让后面的人群知道前方发生了什么事，否则，后面的人群继续向前拥挤，就非常容易发生拥挤踩踏事故。面对混乱的场面，良好的心理素质是顺利逃生的重要因素，争取做到遇事不慌，否则大家都争先恐后往外逃的话，可能会加剧危险，甚至出现谁都逃不出来的惨剧。
