8、ysed data and found the cause of the disease and defeated it.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.This illness causes severe diarrhoea,dehydration,and even death.In the early 19
9、th century,when an outbreak of cholera hit Europe,millions of people died from the disease.As a young doctor,John Snow became frustrated because no one knew how to prevent or treat cholera.In time,he rose to become a famous doctor,and even attended to Queen Victoria when she gave birth.However,he ne
10、ver lost his desire to destroy cholera once and for all.Para.11.Whats the effect of Cholera?2.Whats Johns decision?Careful reading 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
11、 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
12、 more than 500 people died in ten days.He was determined to find out why.Para.21.What are the two theories?Which theory did John Snow think was reasonable?2.What did John Snow ready to do when another outbreak hit London in 1854?Snow began by marking on a map the exact places where all those who die
13、d had lived.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 Cambridge8 Street)had had no deaths.These people worked in the pub at 7 Cambridge Street.They had been given free be
14、er,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 deliv
15、ered to her house every day.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.Through this intervention,the disease was stopped in its tracks.Para.31)How did John get a

17、 by the dirty water from London.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
18、by raw waste.The people who drank this water were much more likely to get cholera than those who drank pure or boiled water.Para.41.How did John Snow further confirm that cholera was spread by germs?2.Whats the conclusion of Johns research?12 Through Snows tireless efforts,water companies began to s
