But he became inspired when he thought about helping ordinary people _3_（暴露）
2、to cholera. This was the _4_（致命的）disease of its day. Neither its cause nor its cure was understood. So many thousands of _5_(受惊吓的) people died every time there was an outbreak. John Snow wanted to face the _6_（挑战） and solve this problem. He knew that cholera would never be controlled until its cause
3、 was found. He became interested in two theories that _7_(可能) 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_8_（受害者）. The second suggested that people _9_（吸收）this disease into their bodies with t
4、heir meals. From the stomach the disease quickly attacked the body and soon the affected person died. John Snow_10_（怀疑） that the second theory was correct but he needed _11_（证据）. So when another outbreak _12_（袭击）London in 1854, he was ready to begin his _13_（询问）. As the disease spread quickly throug
5、h poor _14_（街区）, he began to gather _15_（信息）. In two particular streets, the cholera outbreak was so _16_（严重的） that more than 500 people died in ten days. He was determined to find out why. First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue a
6、bout the cause of the disease. Many of the deaths were near the water _17_ （泵） 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_18_（预见） this, so he made further_19_（调查）
7、. He discovered that 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. It seemed that the water was _20_（责备）. Next, John Snow looked into the source of the water for these two streets. He found that it came from the rive
8、r polluted by the dirty water from London. He immediately told the astonished people in Broad Street to remove the _21_(把手) from the pump so that it could not be used. Soon afterwards the disease slowed down. He had shown that cholera_22_（传播）by germs and not in a cloud of gas. In another part of Lon
9、don, he found supporting evidence from two other deaths that _23_（联系） the Broad Street outbreak. A woman, who had moved away from Broad Street, liked the water from the pump so much that she had it_24_（运送） to her house every day. Both she and her daughter died of cholera after drinking the water. Wi
10、th this extra evidence John Snow was able to _25_（宣布） with certainty that polluted water carried the virus. To prevent this from happening again, John Snow suggested that the source of all the water supplies _26_（检测）. The water companies _27_（命令） not to expose people to polluted water any more. Finally King Cholera was defeated.
