人教版高中地理选修3第五章第一节设计旅游活动教案
点拨：旅游地旅游资源的特色不同，可以安排的旅游活动是不一样的，直接影响对旅游者的吸引力。因此，出游前首先就需要收集旅游地旅游资源的类型、主要游览景区、景点的特色等情况。旅游地的时空可达性直接关系到旅游者从出发地到旅游地，然后再返回出发地的费用和时间。一般来说，居住地与旅游地之间的空间距离过大，会使旅行的时间过长、旅行费用过高，经济距离增加，相应地降低了旅游者的出游能力。而居住地与旅游地相距遥远，也意味着两地之间巨大的环境差异，这会增加对游客的吸引力。旅游服务设施和条件，如旅游交通方式及工具、旅游住宿条件、旅游餐饮的种类和标准、导游服务、旅行费用等信息也都在一定程度上影响着游客的选择。图5．3西藏布达拉宫和图5．4云南香格里拉两幅图片显示了西藏布达拉宫、云南香格里拉与众不同的优美景观，吸引了众多的游客前来观光旅游，成为近年来国内旅游的热点。
人教版高中地理选修1第二章第二节月球和地月系教案
我们将三球仪中的月球放在地球和太阳之间时，对照“月相成因图”，它的暗面完全对着地球，而被太阳照亮的一面正对着太阳，我们看不到月亮，这时正是农历初一，被称为“新月”。又称为“朔”。 过了新月，月亮被照亮的部分慢慢地转向地球。当它从太阳的光辉中出现时，便出现了一丝蛾眉的弯月，此时为农历的初三、初四，因其形似蛾眉，被称为“蛾眉月”。此后，被太阳光照亮的部分越来越多地转向地球，当有一半亮面和一半暗面都对着地球时，明亮部分和黑暗部分的界线似乎像一张弓中没有拉动的弦。此时是夏历初七、初八，称为“上弦月”。这时月亮很明亮，有时在白天也能看见。在往后，月亮明亮部分越来越增大，当它转到与新月正好相反时，被太阳照亮的部分全都对着地球，看起来月亮就似一轮圆月，此时正是 农历十五、十六、十七，称为“满月”，又称为“望”。
人教版高中地理选修1第二章第一节太阳和太阳系教案
教学过程【导入新课】在太阳系中，九大行星就好像一个家庭中的九个兄弟，有许多共性，今天，我们就一起来了解九大行星在运动特征和结构特征上的共同之处。【板书】3．九大行星的运动特征和结构特征【启发引导】请同学们一起阅读地图册上的“太阳系模式图”，读图分析：（1）九大行星在公转的方向、轨道等方面有什么共性？（2）图中符号“i”、“e”代表什么意思？这两组数字能说明什么问题？九大行星公转的方向相同，均为自西向东转，我们称为同向性。符号“i”表示轨道倾角。（简介黄道、黄道面、轨道倾角）各大 行星的轨道倾角都很小，只有水星和冥王星的大一些，最大也不过17°，说明九大行星的公转轨道近似在同一个平面上，我们称之为共面性。符号“e”代表公转轨道椭圆的偏心率，即焦点到椭圆中心的距离与椭圆半长轴之比，它决定椭圆的形状。偏心率越小，越趋向于圆，当偏心率为0时，轨道就是圆。
人教版高中地理选修3第五章第二节参与旅游环境保护教案
通过阅读，了解并掌握生态旅游的行为规范，这些行为规范不仅对保护旅游区的资源环境有利，而且为旅游者提供了个人如何更好地获得更大旅游收益的方法和途径。活动“除了脚印什么也不留下，除了照片什么也不带走。人类应该诗意地栖居在大地之上!”这是美国旅行者协会制定的生态旅游者十条道德准则之一，但作为普通游客也应该做到。结合本地实际，组织一次关于生态旅游的专题讨论会，讨论“诗意地栖居”的含义和意义。提示：可按一下步骤进行1．确定讨论会的准备时间(如一周)。2．将学生分成几组。每组确定一个选题，可自定题目，例如：（1）什么是生态旅游?（2）生态旅游为什么有利于保护环境?（3）学校附近有哪些旅游区适合开展生态旅游?（4）如果你去旅游，你会做些什么来保护环境?（5）介绍一个国内外著名的生态旅游区。3．各组分别收集资料，进行组内讨论，并撰写课题报告。4．各小组推选出一名同学向全班同学介绍各自的研究和看法。
人教版高中地理选修1第二章第三节月相和潮汐教案
创设情境、激发兴趣（5分钟）教师：（锁住屏幕）月相变化与我们人类关系十 分密切。美国著名总统林肯在年轻时担任律师期间曾利用月相变化规律，为当事人进行了成功的辩护，赢得了人们的尊重。月相变化是怎样变化的？月相变化有什么规律，这就是我们今天学习内容。（边演示 学习软件边介绍）我们今天学习主要有三个任务，其中学习任务一要注意在空格中填写农历日期，不认识有关月相的请参照下面的相关学习软件。 完成学习任务二时要注意运用学习软件，首先点击月相，观察日地与月地连线的关系，再观察月亮出没时间现太阳的关系。如满月时，日地与月地连线成1800夹角，当太阳从东方升起时，月亮从西方落下（6时）；当太阳从西方落下时，月亮从东方升起 （18时）。满月可见时间是18时到第二天6时。学习任务三请你先判 断图中月相是否正确，如果不正确，请把你认为正确的月相拖到图中适当位置。下面请你们开始学习。

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

Step 7: complete the discourse according to the grammar rules.Cholera used to be one of the most 1.__________ (fear) diseases in the world. In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention，the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste.

John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

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!

小班综合《蛋宝宝学做解放军》说课稿
此活动选材来源于生活，我们都知道，鸡蛋是幼儿比较熟悉的食物之一，他们基本上每天早晨都会吃一个水煮鸡蛋，以补充身体的营养。幼儿都知道吃鸡蛋可以补充我们身体的能量，会使我们的身体长的更加结实，更加棒。然而由于我们班的幼儿思维较活跃、求知欲强，平时对事物的好奇心较强，凡事爱问：“为什么？”，对周围事物喜欢探根究底，更乐意亲手去尝试一下。他们对鸡蛋充满了极大的兴趣，为此，我选择此教材让幼儿在探索游戏的过程中，能够发挥幼儿的思维能力和动手能力，探索出使蛋站立的多种方法。活动的目标是教育活动的起点和归宿，对活动起着导向作用。根据幼儿的年龄特点及实际情况为依据，确立了认知、能力、情感方面的目标，其中既有独立表达的成分，又有相互融合的一面，目标为：1、让幼儿在探究的过程中探索出让鸡蛋站立的多种方法。2、发展幼儿思维能力与动手能力。3、激发幼儿的好奇心，培养幼儿对周围事物的兴趣。
《一次函数与二元一次方程组》说课稿
一、 说教材、目标这部分内容建立在学生对一元一次方程、二元一次方程组和一元一次不等式等以一次（线性）运算为基础的数学模型的已有认识上，从变化和对应的角度对一次运算进行更深入的讨论。从函数的角度对一次方程（组）、不等式重新进行了分析，这种再认识不是对原有知识的简单回顾复习，而是站在更高起点上的动态分析，是用一次函数将上述三个不同的数学对象起来认识，发挥函数对相关内容的统领作用。通过这部分内容的学习，不仅可以加深学生对方程（组）、不等式等数学对象的理解，而且可以增强对相关知识的内在联系的认识，加强知识间横向与纵向的融会贯通，提高灵活分析和解决问题的能力。本节课是在前两节课已经学完了一次函数与一元一次方程、一元一次不等式的联系之后，对一次函数与二元一次方程（组）关系的探索，是对一次函数及其相关内容更深入、更全面的学习，也是对这部分内容的一个提升和总结。
