【正文】 It infects people’s intestines(腸), causing diarrhea and leg cramps (抽筋).The most mon cause of cholera is by someone eating food or drinking water that has been contaminated(污染) with the bacteria. Cholera can be mild(不嚴重的) or even without immediate symptoms(癥狀), but a severe case can lead to death without immediately treatment.3. Do you know how to prove a new idea in scientific research?Anybody might e out with a new idea. But how do we prove it in scientific research? There are seven stages in examining a new idea in scientific research. And they can be put in the following order. What order would you put the seven in? Just guess.Find a problem→ Make up a question→ Think of a method→ Collect results→ Analyse the results→ Draw a conclusion→ Repeat if necessaryIII. ReadingStep I Prereading1. Do you know John Snow?John Snow is a wellknown doctor in the 19th century in London and he defeated “King Cholera”.2. Do you know what kind of disease is cholera?It is a kind of terrible disease caused by drinking dirty water and it caused a lot of deaths in the old times and it was very difficult to defeat.Let’s get to know how Dr. John Snow defeated “King Cholera” in 1854 in London in this reading passage: Step II Skimming找教案 Read the passage and answer the questions.1. Who defeats “King Cholera“? (John Snow)2. What happened in 1854? (Cholera outbreak hit London.)3. How many people died in 10 days? (500)4. Why is there no death at No. 20 and 21 Broad Street as well as at No. 8 and 9 Cambridge Street? (These families had not drunk the water from the Broad Street pump.) (Optional)Skim the passage and find the information to plete the form below.WhoWhenWhatHowResultJohn Snow1854helping ordinary people exposed to choleraExamining the source of all water supplies and finding new methods of dealing with polluted waster“King Cholera” defeatedStep III ScanningRead the passage and number these events in the order that they happened. 2 John Snow began to test two theories. 1 An outbreak of cholera hit London in 1854. 4 John Snow marked the deaths on a map. 7 He announced that the water carried the disease. 3 John Snow investigated two streets where the outbreak was very severe. 8 King Cholera was defeated. 5 He found that most of the deaths were near a water pump. 6 He had the handle removed from the water pump.Step IV Main idea and correct stage找教案 Read the passage and put the correct stages into the reading about research into a disease.John Snow Defeats “King Cholera”ParagraphStagesGeneral ideas1Find a problem:What cause the cholera?The causes of cholera2Make up a question:Which is right?The correct or possible theory3Think of a method:Test two theoryCollect data on where people were ill and died and where they got their water4Collect results:Mark the deathPlot information on a map to find out where people died or did not die5Analyze the results:Find the resource of the waterLook into the water to see if that is the cause of the illness6Find supporting evidenceFind other evidences to confirm his conclusion7Draw a conclusionThe polluted dirty source of drinking water was to blame for the cause of the London cholera Step V Group discussionAnswer the questions (Finish exercise 2 on Page 3)1. 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.)2. Do you think John Snow would have solved this problem without the map? (No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their waterdrinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.)3. Cholera is a 19th century disease. What disease do you think is similar to cholera today? (Two diseases, which are similar today, are SARS and AIDS because they are both serious, have an unknown cause and need public health care to solve them.)Step VI Using the stages for scientific research and write a summary.Period 2amp。 vi結(jié)束，終止； We concluded the meeting at 8 o’clock with a prayer.
