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. 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.

(一)教材的地位與作用教材的第一部分就從地質(zhì)作用的能量來源的角度,講述了內(nèi)力作用和外力作用及其表現(xiàn)形式;又以地質(zhì)作用不同的表現(xiàn)形式,來說明了激烈迅速的地質(zhì)作用和極其緩慢的地質(zhì)作用,從而使學(xué)生理解地表形態(tài)的變化及這種變化的時(shí)間尺度。第二部分,從三大類巖石的相互轉(zhuǎn)變?nèi)胧?,圖文結(jié)合,闡明了在內(nèi)外力作用的參與下地殼物質(zhì)循環(huán)的過程及其地理意義,該部分內(nèi)容可以看作是全課教材的小結(jié)。(二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):1、結(jié)合實(shí)例,說明內(nèi)力作用的能量來源及其表現(xiàn)形式,理解地殼運(yùn)動是塑造地表形態(tài)的主要作用方式。2、說明外力作用的四種形式及其相互關(guān)系,嘗試識別外力作用形成的不同地貌。3、會用圖文資料說明地殼物質(zhì)循環(huán)的過程及其產(chǎn)生循環(huán)的物質(zhì)基礎(chǔ)——三大類巖石的轉(zhuǎn)化過程。4、培養(yǎng)學(xué)生運(yùn)用地理圖表分析歸納的能力,培養(yǎng)學(xué)生與其它同學(xué)交流、表達(dá)的能力。
(一)教材的地位與作用教材第一部分的順序是:先給學(xué)生洋流的概念以及洋流按照性質(zhì)的分類,接著說明洋流的主要成因與盛行風(fēng)有關(guān)。并結(jié)合風(fēng)帶與洋流模式圖總結(jié)和歸納了洋流的分布規(guī)律。最后,給出世界表層洋流的冬季分布圖,讓學(xué)生讀圖思考的問題主要涉及洋流的分布規(guī)律和原因。教材第二部分闡述了洋流對地理環(huán)境四個(gè)方面的影響。教材的順序和要求與課標(biāo)要求、學(xué)生認(rèn)知規(guī)律有矛盾的地方,需要重組教學(xué)的順序——先由洋流對地理環(huán)境和人類活動的影響的例子來設(shè)置懸念,激發(fā)學(xué)生認(rèn)識的欲望,提供材料歸納世界表層洋流的分布規(guī)律,再探究其主要驅(qū)動力。(二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):①運(yùn)用地圖,從分布位置、運(yùn)動方向、寒暖流的位置來歸納世界表層洋流的分布規(guī)律②畫出世界表層洋流的分布簡單模式圖③掌握洋流的主要成因
(一)教材的地位與作用第一部分的內(nèi)容——山岳的形成,教材首先指出山岳的形成和內(nèi)力作用關(guān)系密切,然后對褶皺山、斷塊山和火山的成因、基本形態(tài)特征和規(guī)模進(jìn)行分析。由于褶皺山和斷塊山是形成于一定的地質(zhì)構(gòu)造上的,所以教材在講述這兩種山岳的形成時(shí),都先從褶皺和斷層這兩種最基本的地質(zhì)構(gòu)造開始講起,并且教材還配以閱讀材料和活動題來幫助學(xué)生更好地掌握這部分內(nèi)容。第二部分的內(nèi)容——山岳對交通的影響,教材主要分析了山岳對交通三方面的影響:對運(yùn)輸線路結(jié)構(gòu)、對線路分布格局和線路延伸方向的影響,并且設(shè)計(jì)了相應(yīng)的活動題幫助學(xué)生理解。(二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):1.了解褶皺的概念和基本形態(tài),掌握正確判斷背斜和向斜的方法,理解褶皺山的概念。2.了解斷層的概念,掌握斷層對地表形態(tài)的影響,理解斷塊山的概念。3.了解火山的形成過程,掌握火山的組成。
(一)教材的地位與作用本節(jié)教材包括三方面的內(nèi)容,(1)全球氣候在不斷變化之中。(2)全球氣候變化的可能影響。(3)氣候變化的適應(yīng)對策三方面說明氣候變化及其對人類活動的影響。從標(biāo)準(zhǔn)的要求看,學(xué)習(xí)的重點(diǎn)不在全球氣候變化本身,而是把全球氣候變化看作是客觀存在的事實(shí),從而探討全球氣候變化對地理環(huán)境及人類活動的影響。從資料中可以看出本節(jié)教學(xué)內(nèi)容涵蓋的時(shí)空跨度非常大,思維的鏈索很長很廣,許多問題涉及到學(xué)科的前沿及人類所關(guān)注的熱點(diǎn),因此,本節(jié)課對學(xué)生而言既有趣味性,又有挑戰(zhàn)性。 (二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):1.通過全球氣候的長期演變圖,學(xué)生了解全球氣候處在波動變化之中。2.通過資料認(rèn)識全球氣候一直處于變化之中并呈現(xiàn)一定變化周期,了解全球氣候變化對地理環(huán)境及人類活動的影響,能夠提出一些氣候變化的適應(yīng)對策。
二、說學(xué)情學(xué)生對自然界中的水循環(huán)已具有一定的生活體驗(yàn)和知識基礎(chǔ),主要問題是學(xué)生還未上升到理性的層面上進(jìn)行分析,而且自然界的水循環(huán)屬于全球尺度和大尺度的地理現(xiàn)象,學(xué)生難以理解,需要教師創(chuàng)設(shè)適當(dāng)?shù)那榫骋龑?dǎo)學(xué)生進(jìn)行新知的建構(gòu)。三、說教法(1)創(chuàng)設(shè)情景:教學(xué)實(shí)踐證明,合理有趣的情境創(chuàng)設(shè),可以引導(dǎo)學(xué)生快速進(jìn)入角色,提高課堂效率(2)討論法:通過組織學(xué)生討論,給學(xué)生提供自主學(xué)習(xí)、合作學(xué)習(xí)、探究學(xué)習(xí)的機(jī)會。(3)多媒體演示法:利用多媒體播放一些直觀的圖片、動畫和數(shù)字資料,把學(xué)生輕松得引入本課,通過形象生動直觀地展現(xiàn)相關(guān)地理事物和現(xiàn)象,提高學(xué)生的感性認(rèn)識,激發(fā)興奮點(diǎn),幫助他們理解課本內(nèi)容。四、說學(xué)法(1)學(xué)會用圖:讓學(xué)生仔細(xì)觀察圖3.2和圖3.3理解水循環(huán)的相關(guān)性(2)學(xué)會探究:學(xué)生思考分析總結(jié)水循環(huán)的地理意義及黃河斷流的原因。
(一)教材的地位與作用該節(jié)教材以水資源作為案例,說明在不同的生產(chǎn)力條件下,水資源的數(shù)量和質(zhì)量對人類生存和發(fā)展的意義。教材首先從水資源的概念入手,介紹世界和我國的水資源的狀況,接著辨證論述水資源與人類社會之間的相互影響,緊扣水資源的數(shù)量和質(zhì)量隨時(shí)空變換,對人類生存與發(fā)展的影響,科技對水資源的利用也發(fā)揮了一定作用,但是隨著人口持續(xù)增長、經(jīng)濟(jì)高速發(fā)展,不能從根本上解決水資源的短缺,因此必須要從開源和節(jié)流兩方面合理利用水資源。此部分內(nèi)容穿插圖片和實(shí)例,特別是通過以色列水資源的利用和咸海面積縮小的兩個(gè)案例,讓學(xué)生明確和鞏固以上觀點(diǎn)。(二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):1.通過讀圖分析數(shù)據(jù)明了水資源的概念。2.結(jié)合事例了解水資源對人類發(fā)展的意義。3.通過分析圖表資料認(rèn)識全球和我國的水資源狀況,提高讀圖分析能力。4.以我國為例,針對我國的水資源利用狀況,結(jié)合所學(xué),學(xué)生合作探究我國水資源合理利用方案,進(jìn)而歸納基本的水資源可持續(xù)利用策略和措施。
學(xué)生已學(xué)習(xí)水循環(huán)和巖石圈物質(zhì)循環(huán),對地理環(huán)境要素有初步的認(rèn)識,對物質(zhì)遷移和能量的交換有一定的了解,已具備基本的地理閱讀分析、提取信息的能力。但學(xué)生還缺乏綜合分析問題解決問題的能力,通過案例來幫助學(xué)生對自然地理環(huán)境整體性的認(rèn)識,還需要補(bǔ)充光合作用、分解作用等知識,并進(jìn)一步培養(yǎng)學(xué)生綜合分析地理問題的能力。三、說教法案例教學(xué)、啟發(fā)式講授四、說學(xué)法學(xué)生原有的地理基礎(chǔ)知識不扎實(shí),學(xué)習(xí)地理方法簡單;但學(xué)生思維活躍,有強(qiáng)烈的求知欲,所以在學(xué)習(xí)的過程中,老師應(yīng)充分利用這一點(diǎn),調(diào)動學(xué)生的積極性,激發(fā)學(xué)生的學(xué)習(xí)興趣。學(xué)案導(dǎo)學(xué)法;合作探究法;案例分析法等,自主學(xué)習(xí)、合作學(xué)習(xí),培養(yǎng)學(xué)生的主動學(xué)習(xí)的能力、團(tuán)隊(duì)精神,增強(qiáng)學(xué)習(xí)效果;體會自然地理環(huán)境的整體性和復(fù)雜性,將學(xué)習(xí)目標(biāo)內(nèi)化到行動上。
(一)教材的地位與作用本節(jié)課是高中地理必修一的最后一節(jié)內(nèi)容,從它的位置安排就可以看出它的定位:即是對自然地理知識的總結(jié)、歸納和融合。所以在教學(xué)中應(yīng)充分聯(lián)系學(xué)生已有的舊知識,做好縱向、橫向聯(lián)系,啟發(fā)學(xué)生的思維,培養(yǎng)學(xué)生的地理思維能力。本節(jié)教材從總體上看,包括兩部分內(nèi)容,一是自然地理環(huán)境的基本特征之一──差異性,二是陸地環(huán)境的地域分異規(guī)律。陸地環(huán)境的地域分異規(guī)律是通過自然帶的地帶性分布規(guī)律來體現(xiàn)的。本節(jié)課主要是以地理分布規(guī)律為中心內(nèi)容,在教學(xué)時(shí),要突出讀圖分析、推斷的環(huán)節(jié),而且所提供的圖表、資料必須有利于學(xué)生分析、推理能力的培養(yǎng)和提高。(二)教學(xué)目標(biāo)(1)知識與技能目標(biāo):1.認(rèn)識和理解自然地理環(huán)境的地域差異特點(diǎn)2.了解地理環(huán)境差異性的分異規(guī)律
