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.

国旗下讲话:“一二.九”运动老师们,同学们:早上好。当历史的车轮即将碾到明天的时候,当挂历上赫然显示12月9日的时候,身为青年的我们,我相信,我们都不会忘记这一天,十二月九日。十二月九日,一个普通但不平凡的日子 。时间倒流 ,回溯到一九三五年 ,阳光依然懒懒散散 ,冬日依旧寒冷凄清 ,但空气却急速的流动 。因为 在北平——历史的故都 ,发生了惊天动地的事件—— 为反对投降和压迫掀起了一二九学生运动 ,到处是挂满的标语 ,到处是飘舞的纸单,到处是舞动的小旗,到处是怒吼的口号 ,到处是热血沸腾的青年。“一二.九”运动的消息传到苏州后,当时的苏州一中与苏州中学以及后来合并到苏州一中的乐益女中的学生,立即与苏州其他学校的学生联合在一起,连续集会,发表宣言,表示一致响应北平学生的爱国行动。1935年12月22日上午,当时苏州一中的学生组成9个宣传队,走上古城街头、观前街闹市区,进行宣讲,散发传单。学生们合唱《义勇军进行曲》,呼吁民众团结一心,组成血肉长城,保卫中华。宣讲的学生登上长凳,揭发蒋介石政府在北平镇压学生,与日本帝国主义达成妥协的罪行。学生们讲得声泪俱下,而有自行车的学生则担任联络员,传递消息。
XX年六一儿童节国旗下讲话稿怎么写,以下是小编精心整理的相关内容,希望对大家有所帮助!XX年六一儿童节国旗下讲话稿 尊敬的老师、亲爱的同学们:“六一”是我们的节日,我们有许多纪念节日的方法,同学之间一句简短的问候,搞一个小小的Party,用几颗糠果靠劳一下自己和亲密伙伴,写几句话记录自己的心情等,在这些看似锁碎的活动中,孕育着我们许多童趣和美好记忆。我也想告诉大家:“六一”是我们父母的节日。当我们共同庆祝的时候,我们的父母或许正在田间劳作;或许正匆匆的赶往工地;或许是刚下夜班往家赶……他们为了什么呢?排在第一位的,肯定就是我们,为了我们能够有一个良好的学习生活环境;为了我们能够一天天长大,学到更多的文化知识;为了他们在走不动的时候,我们能把担子接过来,接替他们支撑起一片天空......所以看到我们脸上洋溢节日的幸福时,他们也是快乐的!“六一”更是我们老师的节日。我们在前进路上会遇到很多的困难和挫折,老师们会及时把我们从弯路上扶回来,使我们阔步走在笔直的大路上。因此,也请向我们的老师说一句”节日快乐!”在这里,我们祝所有同学节日快乐!祝我们的父母节日快乐!祝老师们节日快乐!谢谢大家!
同学们,这个礼拜星期六又是“五一”国际劳动节了,我们年年都欢快地庆祝这个节日,那么你知道它是怎样诞生吗?1889年7月14日,由各国马克思主义者召集的社会主义者代表大会,在法国巴黎隆重开幕。这次大会上,法国代表拉文提议:把1886年5月1日美国工人争取8小时工作制的斗争日,定为国际无产阶级的共同节日。与会代表一致同意,通过了这项具有历史意义的决议。从此,“五一”国际劳动节诞生了。为什么要把这一天定为国际劳动节呢?这还得从19世纪80年代的美国工人运动说起。当时,美国和欧洲的许多国家,逐步由资本主义发展到帝国主义阶段,为了刺激经济的高速发展,榨取更多的剩余价值,以维护这个高速运转的资本主义机器,资本家不断采取增加劳动时间和劳动强度的办法来残酷地剥削工人。在美国,工人们每天要劳动14至16个小时,有的甚至长达18个小时,但工资却很低。沉重的阶级压迫激起了无产者巨大的愤怒。他们知道,要争取生存的条件,就只有团结起来,通过罢工运动与资本家作斗争。工人们提出的罢工口号,就是要求实行八小时工作制。
纲要中指出:引导幼儿接触优秀的儿童文学作品,使之感受语言的丰富和优美。儿童散文诗就是一种介于诗歌和散文之间的儿童文学。它具有诗的意境和散文诗的形式,它注重自然地节奏感和音乐美,篇幅短小,还具有想象丰富,感情真挚,语言天真,意境优美,音调和谐,节奏感强等特点。《秋天的色彩》把菊花、枫叶、松树、大地拟人化,讲述了在它们眼中秋天的颜色。黄、红、绿都是生活中最为常见的颜色,且孩子们都喜欢鲜艳明快的色彩。中班幼儿的语言发展正处于关键期,由词转向短句。想象情感特征会充分展现,并从运用中获得自由表现的愉快体验。所以把本次活动定在中班开展。
(一)教材内容分析大千世界中的生灵万物,都有颜色。颜色既是物质固有的特征,又富有浓郁的情感含义。以色彩及其相关的事物为对象,引发幼儿与它们之间发生互动,这对幼儿在认知建构方面都会产生积极的作用。儿童的世界更是五彩斑斓,就像红、黄、蓝、绿这些颜色一样,在秋景迷人的季节里,孩子们运用自己的感官发现秋天是多彩多姿的。他们感知美丽、丰富的色彩藏在哪里。本教材的重点、难点是知道秋天是美丽多彩的。(二)幼儿情况分析在人们的印象中,秋天应该是金黄色的,因为稻子熟了,树叶黄了,一片丰收的景象。正是由于丰收了,激发幼儿强烈的好奇心与求知欲。我们便可利用现实生活中真实事物的颜色,让幼儿亲身体验、感受到秋天的多样性,从而知道秋天的颜色多种多样。
《纲要》在语言领域中提出:“发展幼儿语言的关键是创设一个能使他们想说、敢说、喜欢说、有机会说并能得到积极应答的环境”以及要“鼓励幼儿大胆、清楚地表达自己的想法和感受,发展幼儿语言表达能力和思维能力。”根据这一目标和要求,结合大班幼儿的年龄特点和语言发展水平,我选择了这节语言活动。根据以上对教材的分析我制定了以下三个目标:1.感受散文诗的优美意境。2.理解散文诗的内容,能有感情的朗诵。3.鼓励幼儿大胆创编与花色相应的梦,激发幼儿的想象力与创编能力。活动重点:理解散文诗的内容,感受散文诗的优美意境。活动难点:鼓励幼儿大胆创编与花色相应的梦,激发幼儿的想象力和创编能力。
大班上学期的幼儿年龄在5岁左右,他们想象力丰富,思维活跃。本班幼儿在以往类似的语言活动中,大多能在老师的引导下理解作品的主要内容,并乐意用自己喜欢的方式创造性的表现文学作品。但是在口语表达方面还是有点欠缺,在集体中发言时态度还是有点拘谨。语言表达不够流畅,有时表现为用词不太恰当。因此本次活动我注意引导幼儿积累一些丰富的词汇,在活动中努力为每个幼儿提供在集体面前大胆表现自己的机会。真正做到让孩子有话可说,有词可用。在口语表达方面有新的进步和突破。
