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.

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.

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.

    1.閱讀圖5.16,說明產(chǎn)業(yè)向國外轉(zhuǎn)移對日本經(jīng)濟的不利影響。點撥:圖5.16直觀的顯示了產(chǎn)業(yè)轉(zhuǎn)移對日本經(jīng)濟的不利影響:形成“產(chǎn)業(yè)轉(zhuǎn)移出去的多,轉(zhuǎn)移進來的少→國內(nèi)生產(chǎn)投資不足,生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉(zhuǎn)移,外資不愿進入”的惡性循環(huán)。2.盡管重化工業(yè)的環(huán)境污染比較嚴重,但是卻能為工業(yè)化的發(fā)展提供堅實的基礎(chǔ),因此成為發(fā)達工業(yè)的象征。日本、韓國的經(jīng)濟發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術(shù)密集型)的階段。(1)為什么日本、韓國在重點發(fā)展重化工業(yè)之前,要先發(fā)展勞動密集型工業(yè)?點撥:重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎(chǔ)和技術(shù)工人,另一方面需要投入大量的資金,先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價的優(yōu)勢,積累資金和造就產(chǎn)業(yè)工人。所以,勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。

    點撥:旅游地旅游資源的特色不同,可以安排的旅游活動是不一樣的,直接影響對旅游者的吸引力。因此,出游前首先就需要收集旅游地旅游資源的類型、主要游覽景區(qū)、景點的特色等情況。旅游地的時空可達性直接關(guān)系到旅游者從出發(fā)地到旅游地,然后再返回出發(fā)地的費用和時間。一般來說,居住地與旅游地之間的空間距離過大,會使旅行的時間過長、旅行費用過高,經(jīng)濟距離增加,相應(yīng)地降低了旅游者的出游能力。而居住地與旅游地相距遙遠,也意味著兩地之間巨大的環(huán)境差異,這會增加對游客的吸引力。旅游服務(wù)設(shè)施和條件,如旅游交通方式及工具、旅游住宿條件、旅游餐飲的種類和標準、導(dǎo)游服務(wù)、旅行費用等信息也都在一定程度上影響著游客的選擇。圖5.3西藏布達拉宮和圖5.4云南香格里拉兩幅圖片顯示了西藏布達拉宮、云南香格里拉與眾不同的優(yōu)美景觀,吸引了眾多的游客前來觀光旅游,成為近年來國內(nèi)旅游的熱點。

    香港的旅游特色在“購”,而購物旅游又進一步促進了其他要素的發(fā)展。據(jù)統(tǒng)計,每年進入香港的國際旅游者中有60%左右的人是為了購物,其購物費用也占全部旅游費用支出的60%左右,使香港這個彈丸之地成為世界的“購物天堂”。思考:1.從旅游六要素的角度看,香港的“購”是如何促進旅游業(yè)發(fā)展的?點撥:到香港購物是許多游客來港旅游的主要動機?!百彙笔窍愀勐糜瘟氐暮诵?,促進了整個旅游業(yè)的發(fā)展。2.香港的地理位置和自由港的地位,為旅游業(yè)的發(fā)展提供了哪些有利條件?點撥:香港是自由港,商品來自世界各地,由于大部分商品不收關(guān)稅,香港的商品價格就相應(yīng)較低。此外,這里每年都有許多換季大減價的促銷活動,能為游客提供真正的實惠。香港店鋪中銷售著世界各地不同特色的貨品,而且大部分服務(wù)行業(yè)的從業(yè)人員都受過專業(yè)訓(xùn)練,態(tài)度殷勤友善,以客為先。購物成為香港吸引游客的一個重要因素,為旅游的發(fā)展提供了極為有利的條件。

    人教版高中數(shù)學(xué)選擇性必修二變化率問題教學(xué)設(shè)計

    導(dǎo)語在必修第一冊中,我們研究了函數(shù)的單調(diào)性,并利用函數(shù)單調(diào)性等知識,定性的研究了一次函數(shù)、指數(shù)函數(shù)、對數(shù)函數(shù)增長速度的差異,知道“對數(shù)增長” 是越來越慢的,“指數(shù)爆炸” 比“直線上升” 快得多,進一步的能否精確定量的刻畫變化速度的快慢呢,下面我們就來研究這個問題。新知探究問題1 高臺跳水運動員的速度高臺跳水運動中,運動員在運動過程中的重心相對于水面的高度h(單位:m)與起跳后的時間t(單位:s)存在函數(shù)關(guān)系h(t)=-4.9t2+4.8t+11.如何描述用運動員從起跳到入水的過程中運動的快慢程度呢?直覺告訴我們,運動員從起跳到入水的過程中,在上升階段運動的越來越慢,在下降階段運動的越來越快,我們可以把整個運動時間段分成許多小段,用運動員在每段時間內(nèi)的平均速度v ?近似的描述它的運動狀態(tài)。
