In general，doctors in those days had two contradictory theories to explain how cholera spread.One theory was that bad air caused the disease.Another was that cholera was caused by an infection from germs in food or water.Snow subscribed to the second theory.It was correct，but he still needed proof.Consequently，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.[2]He was determined to find out why.　 [2]这是一个复合句，that in two...ten days为宾语从句。该从句中的“so...that...”引导结果状语从句。 Snow began by marking on a map the exact places where all those who died had lived　 [3]．There were multiple deaths near the water pump in Broad Street(especially house numbers 16,37,38，and 40)．However，some households(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 free beer，and so had not drunk the water from the pump.Snow suspected that the water pump was to blame.What is more，in another part 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.　 [4]As a result of this evidence，John Snow was able to announce that the pump water carried cholera germs.Accordingly，he had the handle of the pump removed so that it could not be used　 [5]．Through this intervention，the disease was stopped in its tracks. [3]画线部分中的where和who都引导定语从句，分别修饰先行词places和those。 [4]it seems that...表示“似乎……，看起起来……”；had it delivered...every day属于“have sth.done”结构，该结构可表示“请/派别人做某事”。 [5]so that 在此引导目的状语从句。 The truth was that the water from the Broad Street pump had been infected by waste.Moreover，Snow was later able to show a link between other cases of cholera and the different water companies in London.Some companies sold water from the River Thames that was polluted by raw waste.The people who drank this water were much more likely to get cholera than those who drank pure or boiled water. Through Snow's tireless efforts，water companies began to sell clean water，and the threat of cholera around the world saw a substantial decrease.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，thanks to the work of John Snow.Moreover，in his use of maps and statistics，Snow transformed the way scientists study diseases.For this reason，Snow is considered the father of modern epidemiology.,约翰·斯诺战胜“霍乱王” 霍乱曾经是世界上最可怕的疾病之一，直到英国医生约翰·斯诺(向人们)展示了如何能战胜它(它才不那么可怕)。这种疾病会导致严重的腹泻、脱水，甚至死亡。19世纪初，欧洲发生霍乱，数百万人死于这种疾病。作为一名年轻的医生，约翰·斯诺变得沮丧，因为没人知道如何防治霍乱。后来，他成了名医，甚至在维多利亚女王分娩时还照料她。但他从未放弃彻底消灭霍乱的愿望。 总的来说，当时的医生对霍乱的传播的解释有两种相互矛盾的理论。一种理论是这种疾病是由糟糕的空气导致的。另一种理论是霍乱是由食物或水中的细菌感染引起的。斯诺赞同第二种理论。这是对的，但他仍然需要证据。因此，1854年伦敦发生霍乱后，斯诺开始调查。他发现，在两条特定的街道上，霍乱疫情非常严重，十天内就有500多人死亡。他下定决心要找出原因。 斯诺首先在地图上标出了所有死者曾经生活的精确地点。许多死亡病例是在宽街水泵附近(尤其是16号、37号、38号和40号房屋)。然而，一些房屋(如宽街20号和21号，剑桥街8号和9号)却没有人死亡。这些人在剑桥街7号的酒吧工作。他们得到了免费的啤酒，所以没有饮用水泵里的水。斯诺怀疑是水泵的问题。更重要的是，在伦敦的另一个地方，一位妇女和她的女儿从宽街搬走后也因霍乱而死。这个女人似乎非常喜欢(饮用)水泵里的水，因此她每天都让人送水到她家。基于这些证据，约翰·斯诺可以宣布水泵中的水携带了霍乱病菌。因此，他把水泵的手柄拆除了，这样水泵就不能用了。通过这种干预，霍乱才中断了。 事实上，宽街水泵的水已被废物污染了。此外，斯诺后来还发现了其他霍乱病例与伦敦的不同供水公司之间的联系。一些公司出售泰晤士河的水，而河水被未经处理的废物污染了。喝这种水的人比喝纯净水或白开水的人更易得霍乱。 通过斯诺的不懈努力，供水公司开始销售清洁饮用水，世界各地的霍乱威胁也大量减少。然而，霍乱仍然是一个问题。每年，世界各地有数百万人感染霍乱，许多人因霍乱丧生。幸运的是，多亏了约翰·斯诺的努力，我们现在知道如何预防霍乱。此外，斯诺对地图和统计数据的使用也改变了科学家们研究疾病的方法。因此，斯诺被认为是现代流行病学之父。 Ⅰ.Reading for main idea： 1．What's the main idea of the text? 　The_text_mainly_tells_us_how_John_Snow_defeated“king_cholera”．　 2．Match the main idea with each part. ①Para.1　　　A．John Snow's contribution and the title of honor. ②Para.2 B．Two contradictory theories concerning the spread of cholera. ③Paras.3—4 C．The outbreak of cholera and John Snow's ambition. ④Para.5 D．John Snow's method of finding the origin of the disease. 答案：①—C　②—B　③—D　④—A Ⅱ.Reading for details. 1．What do you know about cholera in the early 19th century?
