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.

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease.

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!
新人教版高中英语选修2Unit 2 Bridging Cultures-Discovering useful structures教学设计
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.
高中数学对数函数教师说课稿
一、 教学目标根据教学大纲的要求以及本节课的地位与作用，结合高一学生的认知特点确定教学目标如下：学习目标：1、复习巩固对数函数的图像及性质2、运用对数函数的性质比较两个数的大小能力目标：1、 培养学生运用图形解决问题的意识即数形结合能力2、学生运用已学知识，已有经验解决新问题的能力3、 探索出方法，有条理阐述自己观点的能力
高中数学函数的概念教师说课稿
一、 引入课题1. 复习初中所学函数的概念，强调函数的模型化思想；2. 阅读课本引例，体会函数是描述客观事物变化规律的数学模型的思想：（1）炮弹的射高与时间的变化关系问题；（2）南极臭氧空洞面积与时间的变化关系问题；（3）“八五”计划以来我国城镇居民的恩格尔系数与时间的变化关系问题3. 引导学生应用集合与对应的语言描述各个实例中两个变量间的依赖关系；4. 根据初中所学函数的概念，判断各个实例中的两个变量间的关系是否是函数关系．
小学数学人教版一年级下册《分类与整理》说课稿
今天我说课的内容是人教版一年级数学下册第三单元《分类与整理》。我打算从说教学内容、说教学目标、说教学重难点、说教具准备、说教法学法和说教学过程等方面进行说课。一、 说教学内容一年级数学下册第三单元《分类与整理》要求学生在分类的基础上用自己的方式呈现整理的结果，但又不是正式的学习统计图和统计表，它是为以后学习统计图和统计表打下基础。二、 说教学目标一年级的心理特点和有具体到抽象的认知规律，我确定以下的教学目标：1.使同学能按照给定的标准或自己选定的标准对事物进行分类；能对分类结果进行整理，能够用自己的方式（文字、图画、表格等）呈现分类的结果；能对数据进行简单的分析，能根据数据提出并回答简单的问题。2.在小组交流合作中学习，经历收集信息、分类、统计的过程，体会对同一事物按单一标准分类的一致性。三、说教学重难点根据教材的编排和学生年龄特点，我认为本节课的重点是按单一标准对事物进行分类，本节课的难点是对分类结果进行整理，完成简单的统计活动，也就是能根据结果提出问题，回答问题。针对本节课的重难点，我设计的突破方法是首先通过把黑板上图形摆放整齐，让学生体会分类的意义和作用，然后创设情境，让学生在讨论合作交流中体会按单一标准对事物进行分类得到结果的一致性，最后对分类结果进行整理，完成统计活动。

2．学情分析从学生的认知基础看，学生在初中已经学习了轴对称图形和中心对称图形，并且有了一定数量的简单函数的储备。同时，刚刚学习了函数单调性，已经积累了研究函数的基本方法与初步经验。从学生的思维发展看，高一学生思维能力正在由形象经验型向抽象理论型转变，能够用假设、推理来思考和解决问题．
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。
