1st stage: Find a problem
Read paragraphs 2 & 3 quickly and circle the key words or sentences to put the research stages in order.
Para. 2:
In generalIn 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. He discovered that in two particular streets the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.

2nd stage: Ask a question:
Two contradictory theories

Para. 3:
Snow began by marking on a map the exact places where all those who died 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 Cambridge Street) had had no deaths .

6th stage: Find supporting evidence
7th stage: Draw a conclusion
Snow began by marking on a map … What’s 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.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.

What did Snow do to try to stop the disease
Did it work

Thank you！
Cholera, causing death and other severe illnesses, used to be one of the most scared diseases in the world, until a young British doctor, never losing his desire to defeat cholera, showed how it could be overcome. At first, it was believed cholera was caused by bad air or germs in food or water. Snow subscribed to the latter. When an outbreak struck London in 1854, Snow determined to find out why the outbreak was so severe in two particular streets. Then Snow marked on a map the places where the people who died had lived. On the map the number of deaths in different households was recorded and multiple deaths occurred near the pump in Broad Street, while people who hadn’t drunk the water from the pump, lived. What’s more, a woman and her daughter had died of cholera because they had the water delivered to their house after moving away. As a result, it was proved that the pump water carried cholera germs and the handle was removed. Consequently, the truth was that the water which came from the River Thames had been infected by waste. Thanks to Snow’s tireless efforts, the threat of cholera dropped substantially, people now know how to protect themselves from getting cholera. Snow changed the way scientists study diseases so he is regarded as the father of modern epidemiology.
