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.
北师大版初中七年级数学下册用关系式表示的变量间关系说课稿2篇
一.说教材我今天说课的内容是义务教育课程标准北师大版七年级下册第四单元第二节的《用关系式表示的变量间关系》。在上节课的学习中学生已通过分析表格中的数据，感受到变量之间的相依关系，并用自己的语言加以描述，初步具有了有条理的思考和表达的能力，为本节的深入学习奠定了基础。二.说教学目标本节课根据新的教学理念和学生需要掌握的知识，确立本节课的三种教学目标：知识与能力目标：根据具体情况，能用适当的函数表示方法刻画简单实际问题中变量之间的关系，能确定简单实际问题中函数自变量的取值范围，并会求函数值。过程与方法目标：经历探索某些图形中变量之间的关系的过程，进一步体会一个变量对另一个变量的影响，发展符号感。情感态度与价值观目标：通过研究，学习培养抽象思维能力和概括能力，通过对自变量和因变量关系的表达，培养数学建模能力，增强应用意识。
小学数学人教版三年级下册《除数是一位数的除法》整理和复习说课稿
一、说教材我说课的内容是人教版小学数学三年级下册中的“除数是一位数的除法单元的整理与复习”。这个单元的教学是在学生掌握了整十、整百的数除以一位数的口算、除法的估算和笔算以及验算的基础上进行的，它是以后学习较复杂除法的基础。本节课的教学重点是通过整理与复习，学生进一步理解除法的算理，掌握算法，提高计算能力，教学难点是在整理与复习中形成知识网络，在学习中学会整理与复习的方法。众所周知，整理和复习是为教学中的单元复习、单元知识小结而设计和编排的，以帮助学生达到“再现、整理、巩固已学知识，并使之系统化”的目的。根据复习课型的这一特点和学生的实际情况，我把教学目标分为三个方面：（1）知识性目标：通过复习使学生把“除数是一位数的除法”这一单元的有关计算知识系统化，条理化。（2）能力目标：使学生学会在系统复习的基础上理清知识的脉络，进行分类归纳、有序整理的学习方法，提高学习能力。（3）情感目标：通过自主探索与合作学习，培养学生的创新意识和团队精神，渗透生活中处处有数学的观念，并通过学生解决实际问题，感受数学与实际生活的密切联系。

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!

关于品德是人的第一智慧的第三周国旗下讲话
德是人的第一智慧—第三周国旗下讲话各位老师、同学们：大家早晨好！我今天讲话的题目是《品德是人的第一智慧》，侧重阐述品德和智慧的关系，强调我校学生在校期间的品德要求。我们今天培养和选拔人才的标准是德才兼备，但很少有人思考“德”和“才”的关系。可以这样讲，一个人有怎样的品德，就会有怎样的人生理解和目标，而智慧决定的是追求目标的途径和方法。目标决定方法，方法服务于目标。从这个意义上讲，品德是成功人生的前提，是第一位的；智慧是成功人生的必须，从属于品德。翻开一部人类的历史，凡被人们敬仰的伟人，哪一位不是品德高尚的人？毛泽东、孙中山、钱学森、华罗庚、罗斯福、华盛顿、爱因斯坦、哥白尼等等。同学们试想想，如果你走向社会后事业有成，你会选择一位当年缺乏公德的同学合作吗？没有与人良好的合作关系，才高八斗又有何用？高尚的品德不是与生俱来的，他需要我们一点一滴的做好自律，并自觉接受它律。自律的最高境界就是中国儒家文化强调的“慎独”，即一个人独处时也能保持同样的高尚品德境界，而不是没人看见就随手扔垃圾，随性破坏公物或干点什么见不得人的坏事。
对初中英语教师说课技能的思考与建议
一、认识说课的实质说课是指教师以现代教育理念为指导，在精心备课的基础上，面对同行或教学研究人员，采用口头语言或相关辅助手段，阐述某学科课程或某具体课程的教学设计及其依据的教学研究过程（李崇爱,孟应周,2011）。简单而言，说课就是教师对“教什么”、“怎么教”、“为什么这么教”等问题进行阐述。这样做的目的，一方面可以展现一个教师的教育理论修养、教学组织能力和口头表达能力，另一方面可以帮助教师优化教学设计，反思教学行为，分享教学经验。

幼儿园中班数学教案：大大小小的图形
《刚要》中明确指出：“让幼儿能从生活和游戏中感受事物的数量关系并体验到数学的重要和乐趣”。根据这一要求，利用测量活动将幼儿生活中的内容数量化，不仅能够使幼儿轻松积累测量的经验，而且能从中体验到测量的乐趣。那么，为了激发幼儿测量的兴趣，让幼儿了解测量的知识，积累测量经验，学会做简单的测量记录。因此，本次活动我设计为一个探究性的学习活动，从测量孩子的图形（正方形）开始，利用孩子常见的“回形针”为自然物，在活动中放手让幼儿大胆进行尝试，将幼儿的被动学习变为主动学习。在动手操作中不仅获得知识经验，而且还获得了学习知识的方法和能力的提高。 活动目标： 1、学习用自然物测量图形的边长，探索并初步掌握正确的测量方法。 2、会用圆圈、短线简单的图形记录测量结果。 3、能积极愉快的参与活动，体验测量的乐趣。 活动准备： 教具：大小不同的正方形、各种图示、照相机。 学具：每人一个正方形、彩色回形针若干、水彩笔。
