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. 以上黑體部分在句中作表語。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

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. He wanted to find the _3_____ of cholera in order to help people ___4_____ it. In 1854 when a cholera __5__ London, he began to gather information. He ___6__ on a map ___7___ all the dead people had lived and he found that many people who had ___8____ (drink) the dirty water from the __9____ died. So he decided that the polluted water ___10____ cholera. He suggested that the ___11__ of all water supplies should be _12______ and new methods of dealing with ____13___ water be found.

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.

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!

頻率的穩(wěn)定性教案教學設計
活動內容：教師首先讓學生回顧學過的三類事件，接著讓學生拋擲一枚均勻的硬幣，硬幣落下后，會出現(xiàn)正面朝上、正面朝下兩種情況，你認為正面朝上和正面朝下的可能性相同嗎？（讓學生體驗數(shù)學來源于生活）?；顒幽康模菏箤W生回顧學過的三類事件，并由擲硬幣游戲培養(yǎng)學生猜測游戲結果的能力，并從中初步體會猜測事件可能性。讓學生體會猜測結果，這是很重要的一步，我們所學到的很多知識，都是先猜測，再經(jīng)過多次的試驗得出來的。而且由此引出猜測是需通過大量的實驗來驗證。這就是我們本節(jié)課要來研究的問題（自然引出課題）。
角平分線的性質教案教學設計
這是本節(jié)課的重點。讓同學們將∠aob對折，再折出一個直角三角形（使第一條折痕為斜邊），然后展開，請同學們觀察并思考：后折疊的二條折痕的交點在什么地方？這兩條折痕與角的兩邊有什么位置關系？這兩條折痕在數(shù)量上有什么關系？這時有的同學會說：“角的平分線上的點到角的兩邊的距離相等”.即得到了角平分線的性質定理的猜想。接著我會讓同學們理論證明，并轉化為符號語言，注意分清題設和結論。有的同學會用全等三角形的判定定理aas證明，從而證明了猜想得到了角平分線的性質定理。

李商隱詩兩首教學設計教案
我們不妨將主旨放在“莊生曉夢迷蝴蝶，望帝春心托杜鵑。滄海月明珠有淚，藍田日暖玉生煙。”二聯(lián)之前，那么，事情就變得簡單起來了：華年如莊生曉夢迷蝴蝶；華年如望帝春心托杜鵑；華年如滄海月明珠有淚；華年如藍田日暖玉生煙。從課下注釋，我們很容易就可以看出，這四句每一句都在用典。因此，我們通過對典故的解讀，然后加以整理，將其理順，似乎就可以完成對詩歌內容的解讀；至于什么悼亡、愛情，不妨拋之腦后，畢竟，沒有那些其他的主題，也并沒有讓詩歌失色，而加上這些捉摸不定的主題，只是讓詩歌增加了所謂的神秘色彩，徒增閱讀難度而已。

二年級音樂欣賞貓和老鼠教案教學設計
阿倫.科普蘭是美國現(xiàn)代音樂的倡導者，1920年創(chuàng)作的《貓和老鼠》是一首音樂形象鮮明，詼諧有趣的鋼琴演奏曲。樂曲栩栩如生的表現(xiàn)了貓捉老鼠的情景，不協(xié)和和弦以及多變的節(jié)奏，使作品充滿了現(xiàn)代的氣息。樂曲由引子、A、B、A、尾聲組成。引子中速貓的主題。貓驕傲的懶洋洋的走向高處，兇險的目光窺視周圍。第一樂段開始速度非?？?，刻畫了老鼠的形象。接著貓在屋子里冷漠的巡視，老鼠靈巧的跑來跑去，一場貓捉老鼠的游戲開始了。第二樂段老鼠得意的逃掉了，它，輕快的跑上跑下。遠處傳來教堂鐘聲的回響。貓懶洋洋的自我陶醉，老鼠見狀，極其靈巧的故意挑逗貓。第三樂段貓再次撲向老鼠，這次老鼠終于被貓逮著了。美聲慢板送葬去曲，裝死的老鼠一瘸一拐的拖著殘腿悄悄的溜走了。在這部作品中作曲家運用了自己獨特的“躍進式”旋律，緊張不安的活躍節(jié)奏，快速的托卡塔（密集）音型、豐富的和聲運用樸實清晰的色彩和富于廣度和深度的想象力。讓人仿佛看到貓和老鼠追逐、爭斗的情形。
