John Snow was a famous doctor in London and he was kind enough to help the ordinary people

exposed

to cholera that could not be cured

at that time. There were two theories about the cause of cholera, one of which was to believe that people

absorbed

the disease into their bodies with their meals.

John Snow

suspected that the second one was correct, so he collected information to test the two theories. He carried out a series of researches and the results showed that the water was to

blame. So he told the people in Broad Street to remove the handle form the

pump

at once. The disease soon slowed down. After that John Snow found two other deaths that were

linked

to the Broad Street outbreak. A woman liked the water so much that she had it

delivered

to her house from Broad Street. With this extra evidence John Snow was able to

announce

with certainty that polluted water carried the virus. John Snow suggested the water companies should be

instructed

not to supply people with polluted water. Finally “ King Cholera” was defeated. Step 5 Homework To find the usage of the new words and expression in the passage. To underline the sentence patterns in the passage
