[?nisθizi'?l?d?i]John Snow ( 1813~ 1858)?Step1 Fast reading 1．Let the students read the text and then answer the following questions. (1)In John Snow’s age, cholera is the deadly disease, why? _________________________________________ _________________________________________ 答案：Neither its cause nor its cure was understood.(2)There were two theories which could explain its cause. Which one did John Snow believe in? ____________________________________ ____________________________________ 答案：People absorbed cholera into their bodies with their meals.(3)Number these events in the order that they happened.
John Snow began to test two theories.
An outbreak of cholera hit London in 1854.
John Snow marked the deaths on a map.
He announced that the water carried the disease.

King Cholera was defeated.
He found that most of the deaths were near a water pump.
He had the handle removed from the water pump.21473856?Step Two：Careful reading1．Let the students read para.3-6 carefully and then fill in the blank.
