(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['keimbridʒ] Street?(These families had not drunk the water from the Broad Street pump.)JOHH SN OW DEFEATS “KING CHOLERA”John Snow was a famous doctor in London - so expert, indeed, that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people exposed to cholera. This was the deadly disease of its day. Neither its cause nor its cure was understood. So many thousands of terrified people died every time there was an outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause was found.He became interested in two theories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died.John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1854, he was ready to begin his enquiry. As the disease spread quickly through poor neighbourhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue about the cause of the disease. Many of the deaths were near the water pump in Broad Street (especially numbers 16, 37, 38 and 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame.Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used. Soon afterwards the disease slowed down. He had shown that cholera was spread by germs and not in a cloud of gas.In another part of London, he found supporting evidence from two other deaths that were linked to the Broad Street outbreak. A woman, who had moved away from Broad Street, liked the water from the pump so much that she had it delivered to her house every day. Both she and her daughter died of cholera after drinking the water. With this extra evidence John Snow was able to announce with certainty that polluted water carried the virus.To prevent this from happening again, John Snow suggested that the source of all the water supplies be examined. The water companies were instructed not to expose people to polluted water any more. Finally "King Cholera" was defeated.1）.Read 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.2）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 water-drinking 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.1. defeat① vt. to win a victory over someone in a war, competition, game etc.打败，战胜，使受挫I’ve tried to solve the problem, but it defeats me!Our team defeated theirs in the game.② n.失败，输failure to win or succeedThis means admitting defeat.They have got six victories and two defeats.[辨析]win, beat与defeat①win “赢得”赛事、战事、某物；后接人时，意为“争取赢得…的好感或支持；说服”②beat “战胜”“击败”比赛中的对手，可与defeat互换We beat / defeated their team by 10 scores.They won the battle but lost many men.The local ball team won the state championship by beating / defeating all the other teams.I can easily beat /defeat him at golf.He is training hard to win the race and realize his dream of becoming a champion at the 2008 Olympic Games.2. expert①n. someone who has a special skill or special knowledge of a subject专家，能手an expert in psychology an agricultural expert② a. having special skill or special knowledge of a subject熟练的，有专门技术的an expert rider an expert job需专门知识的工作He is expert in / at cooking.3. attend vt. &vi 参加，注意，照料① be present at参加attend a ceremony / lecture / a movie / school / class / a meetingI shall be attending the meeting.Please let me know if you are unable to attend the conference.② attend to (on): to look after, care for, serve伺候, 照顾，看护The queen had a good doctor attending on her.Dr Smith attended her in hospital. 治疗Are you being attended to?接待Mother had to attend to her sick son.③ attend to处理，注意倾听attend to the matterA nurse attends to his needs.Can you attend to the matter immediately?I may be late – I have got one or two things to attend to.Excuse me, but I have an urgent matter to attend to.[辨析]attend, join, join in与take part in①attend指参加会议、上课、上学、听报告等②join 指加入某组织、团体，成为其中一员③join in指加入某种活动；表示与某人一起做某事join sb. in sth.④take part in指参加正式的、有组织的活动，切在活动中起积极作用Only 2 people attended the meeting.He joined the Communist Youth League in 2007.Will you join us in the game?We often tale part in the after-class activities.4. expose : to show sth. that is usually covered暴露expose sth. to the light of day 把某事暴露于光天化日之下I threatened to expose him ( to the police). 我威胁要(向警察)揭发他.He exposed his skin to the sun.他把皮肤暴露在阳光下.The old man was left exposed to wind and rain.When he smiled he exposed a set of perfect white teeth.5. cure vt. & n. to make someone who is ill well agian治疗,痊愈When I left the hospital I was completely cured.①cure sb of a diseaseWhen you have a pain in your shoulders, you will go to see a doctor.
