5、Warming Up & Reading PrereadingJOHN SNOW DEFEATS “KING CHOLERA”John Snow was a famous doctor in London so expert， indeed, that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people exposed to cholera. This was the deadly disease of
6、 its day. Neither its cause nor its cure was understood. So many thousands of terrified people died every time there was an outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause was found.He became interested in two th
7、eories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the diseas

10、侵袭的”。约翰斯诺战胜“霍乱王”第12段译文约翰斯诺是伦敦一位著名的医生他的确医术精湛，因而成了维多利亚女王的私人大夫。但当他一想到要帮助(那些)受到霍乱威胁的普通百姓，他就感到很振奋。霍乱是当时最致命的疾病。人们既不知道它的病源，也不知道它的治疗方法。因此，每次爆发霍乱时就有成千上万惊恐的人死去。约翰斯诺想面对这个挑战，解决这个问题。他知道在找到病源之前，疫情是无法控制的。对于霍乱是如何致人死亡的，当时有两种相对合理的看法，斯诺对这两种看法比较感兴趣。第一种看法是霍乱病毒在空气中繁殖，它像一股危险的气体到处飘浮，直到找到受害者为止。第二种看法是人们是在吃饭时把这种病毒引入体内的。 疾病从胃里
11、发作而迅速殃及全身，患者很快就会死亡。John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1854, he was ready to begin his enquiry. As the disease spread quickly through poor neighbourhoods， he began to gather information. In two particular streets, the

13、do下定决心做第3段译文约翰斯诺推测第二种理论是正确的， 但他需要证据。因此，在1854年伦敦再次暴发霍乱时，约翰斯诺就准备开始他的调查。当霍乱在贫民区迅速蔓延的时候，他就开始收集资料。在两条特定的街上霍乱流行得很严重，以至于10天内就有500多人死亡。他决心要查明原因。First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue about the cause of the disease. Many of the deaths were
14、 near the water pump in Broad Street (especially numbers 16, 37, 38 and 40)He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub
15、at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame.Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used. Soon afterwards the disease slowed down. He had shown that cholera was spread by germs and not in a cloud of gas.m
