Background introduction to John Snow
John Snow (1813-1858) was born and worked as a doctor in Great Britain. He was originally an anesthetist(麻醉师).He was so famous that he became the doctor for Queen Victoria at the births of her many children. Four outbreaks of cholera in the 1830s and 1840s killed many people in England. In 1854, the most terrible outbreak of cholera which ever occurred in the kingdom began. It was so violent and sudden that 127people died in the first three days.
Some knowledge about Cholera
Cholera is the illness caused by a bacterium called Varian cholera. If it infects people’s intestines(肠胃), it may cause diarrhea(腹泻), vomiting (呕吐) and cramps(腹痛). The most common cause of cholera is by eating food or drinking water that has been polluted by the bacteria. Cholera can be mild(不严重的) or even without symptoms(症状), but without immediate treatment a severe case can lead to death.
Task 2: Skimming
Reading the passage quickly and answer the question.
1. What’s the main idea of the passage?
A. John Snow was a well-known doctor in London.
B. The cause of Cholera was polluted water.
C. The source of all drinking water should be examined.
D. How John Snow collected, analyzed data and found the cause of
the disease and solved it .
2. the main idea of each paragraph:(pair work)
Para 1:???Find a problem （What causes cholera?）
Para 2:???Make a question（Which theory is correct?）
Para 3: Think of a method（Gather information on those who were ill or died.）
Para 4: Collect results （Put information on a map to find out where people died or did not die.）
Para 5: Analyze the results （Analyze the water to see if that is the cause of the illness.）
Para 6: Find supporting evidence（Find other evidence to support the analysis.）
Para 7: Draw a conclusion（It was certain that polluted water carried the disease.）
设计意图: 让学生基本了解本文文章的章节安排和文章的主线。这一环节要求学生在规定的时间内通过快速浏览文章得出其大意，初步了解文章的主要内容,帮助学生理清文章的脉络，培养学生领悟和分析语篇的能力。
Task 4: Detailed reading (competition)
Read the text paragraph by paragraph to get details.
