Period 2　课时练案 课文整体阅读(Reading and Thinking) JOHN SNOW DEFEATS “KING CHOLERA” Cholera used to be one of the most feared diseases in the world，until a British doctor，John Snow，showed how it could be overcome[1]．This illness causes severe① diarrhoea，dehydration，and even death．In the early 19th century，when an outbreak of ② cholera hit③ Europe[2]，millions of people died from the disease．As a young doctor，John Snow became frustrated④ because no one knew how to prevent or treat cholera[3]．In time⑤，he rose⑥ to become a famous doctor，and even attended to⑦ Queen Victoria when she gave birth⑧．However，he never lost his desire to⑨ destroy cholera once and for all⑩． Period 2　课时练案 课文整体阅读(Reading and Thinking) [1]how引导的宾语从句，从句使用了被动语态。 [2]when引导的非限制性定语从句，修饰the early 19th century。 [3]“特殊疑问词how＋动词不定式”结构，作谓语动词knew的宾语。 Period 2　课时练案 课文整体阅读(Reading and Thinking) In general⑪，doctors in those days had two contradictory⑫ theories to explain how cholera spread[4]．One theory was that bad air caused the disease[5]．The other was that cholera was caused by an infection⑬ from germs⑭ in food or water．Snow subscribed to⑮ the second theory．It was correct，but he still needed proof⑯．Consequently⑰，when an outbreak of cholera hit London in 1854，Snow began to investigate．He discovered that in two particular streets the cholera outbreak was so severe that more than 500 people died in ten days[6]．He was determined to⑱ find out why． Period 2　课时练案 课文整体阅读(Reading and Thinking) [4]不定式短语作后置定语，修饰theories。 [5]that引导表语从句。 [6]that引导的宾语从句，从句中又含有“so...that...”结构引导的结果状语从句。 Period 2　课时练案 课文整体阅读(Reading and Thinking) Snow began by marking⑲ on a map the exact places where all those who died had lived．[7]There were multiple⑳ deaths near the water pump㉑ in Broad Street (especially house numbers 16，37，38，and 40)．However，some households㉒(such as 20 and 21 Broad Street，and 8 and 9 Cambridge Street) had had no deaths．These people worked in the pub at 7 Cambridge Street．They had been given[8] free beer，and so had not drunk the water from the pump．Snow suspected㉓ that the water pump was to blame㉔．What is more㉕，in another part Period 2　课时练案 课文整体阅读(Reading and Thinking) of London，a woman and her daughter had died of cholera after moving away from Broad Street．It seemed that the woman liked the water from the pump so much that she had it delivered to her house every day．[9]As a result of this evidence，John Snow was able to announce that the pump water carried cholera germs．Accordingly㉖，he had the handle㉗ of the pump removed so that it could not be used[10]．Through this intervention㉘，the disease was stopped in its tracks． Period 2　课时练案 课文整体阅读(Reading and Thinking) [7]where引导定语从句，修饰the exact places。该定语从句中又包含另一个定语从句who died，该定语从句修饰those。另外，还要注意这个句子的语序，marking有个较长的宾语the exact places...had lived，为了平衡句子结构，该宾语被后置，移到了地点状语on a map之后。 [8]过去完成时的被动语态。 [9]It seems that...表示“似乎……，看起来……”；the woman liked...so much that...属于“so...that...”结构；had it delivered属于“have sth．done”结构，该结构可表示“请/让别人做某事”。 [10]so that引导目的状语从句。 Period 2　课时练案 课文整体阅读(Reading and Thinking) The truth was that the water from the Broad Street pump had been infected by waste[11]．Moreover，Snow was later able to show a link㉙ between other cases㉚ of cholera and the different water companies in London[12]．Some companies sold water from the River Thames that was polluted by raw㉛ waste．The people who drank this water[13] were much more likely to㉜ get cholera than those who drank pure㉝ or boiled water㉞[14]． Period 2　课时练案 课文整体阅读(Reading and Thinking) [11]that引导的表语从句，从句谓语用了过去完成时的被动语态。 [12]between...and...是介词短语，作后置定语，修饰前面的名词link；a link between...and...表示“……和……之间的联系”。 [13]who引导的定语从句，修饰people。 [14]who引导的定语从句，修饰those。 Period 2　课时练案 课文整体阅读(Reading and Thinking) Through Snow's tireless efforts㉟，water companies began to sell clean water，and the threat of cholera around the world saw a substantial decrease㊱[15]．However，cholera is still a problem．Each year，millions of people around the world get cholera and many die from it．Fortunately，we now know how to prevent cholera[16]，thanks to㊲ the work of John Snow．Moreover，in his use of maps and statistics㊳，Snow transformed㊴ the way scientists study diseases[17]．For this reason，Snow is considered the father of modern epidemiology． Period 2　课时练案 课文整体阅读(Reading and Thinking) [15]此处使用了拟人的修辞手法。该句是无生命名词作主语，saw在此意为“见证”，句子的主语常常是时间或者地点等。 [16]“特殊疑问词how＋动词不定式”结构作宾语。 [17]定语从句，the way为先行词，the way 与scientists之间省略了that。 Period 2　课时练案 课文整体阅读(Reading and Thinking) 约翰·斯诺 战胜“霍乱王” 在英国医生约翰·斯诺向人们展示如何战胜霍乱之前，霍乱曾是世界上最令人恐惧的疾病之一。它可导致严重腹泻、脱水甚至死亡。十九世纪初，霍乱暴发，肆虐欧洲，数百万人丧命。由于当时无人知道如何预防或治疗霍乱，年轻的约翰·斯诺医生很沮丧。后来，他成了一位名医，甚至照料分娩的维多利亚女王。然而，他始终没有放弃彻底根除霍乱的愿望。 Period 2　课时练案 课文整体阅读(Reading and Thinking) 关于霍乱的蔓延方式，当时医生大体上有两种截然不同的看法。一种看法是空气污染引发，另一种看法是食物或饮用水中的细菌感染导致霍乱。斯诺赞同第二种看法。这一看法是正确的，但他仍需要证据。因此，1854年伦敦暴发霍乱时，斯诺便开始调查。他发现霍乱疫情在两条街道上尤为严重，十天内就有500多人死亡。他决心查明原因。 Period 2　课时练案 课文整体阅读(Reading and Thinking) 斯诺首先在地图上标出所有死者住所的确切位置。宽街水泵附近有多例死亡(尤其是16号、37号、38号及40号住宅)，但是有些住户(如宽街20号和21号以及剑桥街8号和9号)却无人死亡。这些幸存者在剑桥街7号的酒吧工作，酒吧为他们提供免费啤酒，因此没有喝水泵抽上来的水。斯诺怀疑水泵就是罪魁祸首。此外，在伦敦的另一个区域，一名妇女和她的女儿从宽街搬来后死于霍乱。该妇女似乎非常喜欢从水泵抽上来的水，每天都让人从那里打水运到家里来。有了这个证据，约翰·斯诺就能够宣布水泵抽上来的水携带霍乱病菌。于是，他让人拆掉了水泵的把手，这样水泵就用不成了。这一干预举措遏制了疾病的蔓延。 Period 2　课时练案 课文整体阅读(Reading and Thinking) 事情的真相是宽街水泵抽上来的水被废弃物污染了。此外，斯诺之后还证明了另外几起霍乱病例与伦敦多家饮用水公司有关。有些公司出售的水取自被未处理的废弃物污染的泰晤士河。与饮用纯净水或开水的人相比，饮用被污染的水的人更容易染上霍乱。 经过斯诺的不懈努力，饮用水公司开始出售洁净水，世界各地霍乱的威胁大幅降低。然而，霍乱仍是问题。每年全球有数百万人感染霍乱，其中许多人因此丧生。幸运的是，由于约翰·斯诺的努力，我们现在知道了如何预防霍乱。此外，通过使用地图和数据，斯诺改变了科学家研究疾病的方式。因此，斯诺被誉为现代流行病学之父。 Period 2　课时练案 课文整体阅读(Reading and Thinking) $
