In 1854, “the most terrible outbreak of cholera which ever occurred in the kingdom” began. It was so violent and sudden that 127 people died in the first three days.The terrible choleraBacteria/germs
of choleraWhat was the cause of this illness?
How did John Snow find it out?Skim the text and find the main idea of the text. The passage is mainly about: _______________________________
________________________ How John Snow found the cause of
the cholera and defeated it. Fast—reading:Read the passage quickly
and find the number below
and the relevant happenings
in the passage.The first suggested that…multiplied
in the air; The second suggested…
absorbed this disease into their bodies
with their meals.Another outbreak hit London.More than 500 people had died
in 10 days.These numbers in Broad Street
near the water pump had many
of the deaths20 and 21 Broad Street and 8 and 9
Cambridge Street had no deaths….
They didn’t drink the water
from the Broad Street pump.These families worked in
the pub at 7 Cambridge Street.16372089pump3840BROAD STREETCAMBRIDGE STREET21John Snow's Cholera Map7PubWhat is the problem?The cholera was the most deadly disease
of its day. Neither its cause, nor its cure
was understood.What caused cholera?Make a question: Which theory to believe in? Idea 1Idea 2Cholera multiplied in the air without
reason. A cloud of dangerous gas would
float around until it found its victims.People absorbed it with their meals.Which one do you believe more?
What about John Snow?A map of Broad StreetWhat method did he use?Broad StreetMany deaths happened here.No death happened here.It seemed the water from the pump was
to blame. What did he do next?Public house(Para 6) What was another supporting evidence?(Para 5) He looked into the source of the water…John Snow was able to announce
with certainty that polluted water
carried the virus.Read the passage and number these events
in the order that they happened.John Snow began to test two theories.An outbreak of cholera hit London in 1854.He announced that the water carried
the disease.John Snow marked the deaths on a map. 2147Careful—reading: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.John Snow investigated two streets where
the outbreak was very severe.3856What caused cholera?Which theory is correct?Collect data on those who
were ill or died and where
they got their water.Fill in the blanks. Plot information on a map to
find out where people died or
did not die.Analyse the water to see if that
is the cause of the illness.Find other evidence to
support the analysis.The water is to blame. The
source of all drinking water
should be examined so
that it is safe.Match themPara 7Prevention of Cholera1. John Snow believed Idea 2 was right. How did he finally prove it?John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.Read and answer the questions.2. Do you think John Snow would have solved this problem without the map? Give a reason.No. The map helped John Snow organize his
ideas. He was able to identify those households
that had many deaths and check their water-
drinking habits. He identified those houses
that had no deaths and surveyed their drinking
habits. The evidence clearly pointed to the
polluted water being the cause.3. Cholera was a 19th century disease. What disease do you think is similar
to cholera today?Four diseases, which are similar today, are
SARS, AIDS, TB (肺结核) and bird-flu,
because they are both very serious, have
an unknown cause and need public health
care to solve them.1. The passage mainly tells us that ____.
