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. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase.

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. What disease do you think is similar to cholera today?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.keys:1. 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!

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.

幼儿园中班科学说课稿 吹泡泡
为了构建积极有效的师幼互动，让幼儿在自主状态下主动建构知识和经验，体现真正有价值、有意义的学习，以此提高教育的有效性。我有意识运用了以下三种教育方法：一“顺”，二“引”，三“助”。 “顺”即顺应幼儿的活动，为他们提供有关主题的资料及活动所需的材料，使幼儿按照自己的意愿进行探索。在这个过程中，教师给足幼儿自由的时间与空间，提供丰富的材料。 “引”即用巧妙的方法引导幼儿生成和建构新的主题或知识。在这个过程中教师通过观察思考和设置开放性问题的策略，以玩伴的身份参与到幼儿的活动中，与幼儿有效地互动。让幼儿在“玩”中学，在学中“玩”。 “助”即教师在适当的时候“助”幼儿一臂之力，对幼儿进行点拔，借助当时的情景、材料，直接地提出主题，把幼儿的学习兴趣推向深入。
幼儿园中班科学说课稿 火箭升空
在幼儿进行实验的时候，大部分孩子都能够认真的去寻找反作用力，只有极个别孩子只对某一样东西感兴趣，所以就不太主动的去进行其他的探索实验，根据这个情况，我对这样的孩子也进行了正确的引导，在实验结束的时候，大部分孩子都能够在不同的物体中找到反作用力。 我上的这节课是科学活动《火箭升空》这是整合课程《交通工具博览会》主题中的一个活动。 下面我先说一下这节课的活动目标： 1、拓展幼儿的想像力及对科学的探索能力。 2、尝试了解火箭升空的动力。 3、初步了解反作用力。 首先，我说一下这节课的设计意图，在《交通工具博览会》主题活动中，我们班的孩子对于火箭都非常好奇，感兴趣，平时提到火箭孩子们也都很兴奋，他们虽然知道火箭，喜欢火箭，但是火箭对于他们来说具体是一个什么样的概念，他们还不是很了解。
幼儿园中班科学说课稿：吹泡泡
二、说活动目标： 根据中班幼儿的年龄特点，和建构知识的能力我为本次活动制定了如下三条目标：1、运用各种感官感知泡泡的特性，了解不同形状的工具吹出的泡泡都是圆的。2、尝试运用记录的方式表达、交流探索的过程和结果，发展学习的自主性。3、在探究活动过程中，体验发现的乐趣。三、说活动重点、难点： 此次活动设计的最终目的是激发幼儿更深层的探究“泡泡特性以及不同形状的工具吹出的泡泡都是圆的”欲望。因此我将本次活动的重点确定为“运用各种感官感知泡泡的特性，了解不同形状的工具吹出的泡泡都是圆的”。将“尝试运用记录的方式表达、交流探索的过程和结果，发展学习的自主性”确定为本次活动的难点。
幼儿园中班科学说课稿：火箭升空
我上的这节课是科学活动《火箭升空》这是整合课程《交通工具博览会》主题中的一个活动。 下面我先说一下这节课的活动目标：1、拓展幼儿的想像力及对科学的探索能力。2、尝试了解火箭升空的动力。3、初步了解反作用力。 首先，我说一下这节课的设计意图，在《交通工具博览会》主题活动中，我们班的孩子对于火箭都非常好奇，感兴趣，平时提到火箭孩子们也都很兴奋，他们虽然知道火箭，喜欢火箭，但是火箭对于他们来说具体是一个什么样的概念，他们还不是很了解。 这也正是《纲要》中所提出的：从生活或媒体以及幼儿熟悉的科技成果入手，引导幼儿感受科学技术对生活的影响，培养他们对科学的兴趣，和对科学家的崇敬，所以我就抓住了孩子们的这个兴趣点，来设计了《火箭升空》这节课。
学雷锋精神，创建文明校园说课稿
雷锋精神是什么？这一环节是让学生用简单的词语或句子概括。通过这一活动，让学生概括出雷锋精神的内涵：像无私奉献、乐于助人、为人民服务、勤俭节约、尊老爱幼、勤奋好学、干一行爱一行、言行一致等等都是雷锋精神的体现。我们少年儿童是中国的未来和希望，雷锋精神的发扬和光大，创建文明校园的任务就落在他们的肩上，所以在这里我还设计了为发扬雷锋精神，创建文明校园“我该怎么做”这样的问题，目的就是让他们一起行动起来，学雷锋做好事，并制作了“荣誉”旗，奖励身边的好人好事。活动延伸：这里我设计了一个角色游戏活动——我要义卖献爱心，这个游戏学生们表现得非常积极，他们收集了自己不要的小文具或小玩具，将他们拿到集市上去卖，卖东西获得的钱，捐给王奶奶的孙女，因为王奶奶的孙女生病了，无钱治病。我觉得这个游戏使学生们懂得，一个人只要有爱心，只要愿意去帮助别人，无论什么方式都行，而且在游戏活动中孩子们体会到了帮助别人是一件多么多么快乐的事呀。
