Cholera used to be one of the most feared ______(disease) in the world, until a British doctor. John Snow, showed how it could be_______(overcome). This illness causes severe diarrhoea, dehydration, and even death. In ______ early 19th century, ______ an outbreak of cholera hit Europe, millions_______ people died from the disease. _____ a young doctor, John Snow became _________(frustrate) because no one knew how ______(prevent) or treat cholera. In time, he rose to become a famous doctor, and even attended_____ Queen Victoria when she gave birth.______, he never lost his desire_______(destroy) cholera once and for all.
______general, doctors in those days had two __________(相互矛盾的） theories to explain how cholera spread. One theory was____ bad air caused the disease. Another was that cholera was caused by an infection from germs in food or water. Snow subscribed _____ the second theory. It was correct, but he still needed proof. ________(consequent), when an outbreak of cholera hit London in 1854, Snow began to investigate. He discovered that in two particular streets the cholera __________（爆发）was so severe______ more than 500 people died in ten days. He was determined_________(find) out why.
Snow began by marking on a map the exact places________ all those who died had lived. There were multiple deaths near the water pump in Broad Street (especially house numbers 16, 37, 38, and 40). However, some households (such as 20 and 21 Broad Street, and 8 and 9 Cambridge Street) had had no deaths. These people worked in the pub at 7 Cambridge Street. They had been given free beer, and so had not _________(drink) the water from the pump. Snow suspected that the water pump was ________(blame). What is more, in another part of London, a woman and her daughter had died of cholera after moving away from Broad Street. It seemed_______ the woman liked the water from the pump ______ much that she had it ________(deliver) to her house every day. As a result_____this evidence, John Snow was able to announce that the pump water carried cholera germs. Accordingly, he had the handle of the pump________(remove) so that it could not be used. Through this intervention, the disease was stopped in its tracks.
The truth was that the water from the Broad Street pump had been infected by waste. Moreover, Snow was later able to show a link between other cases of cholera _____ the different water companies in London. Some companies sold water from the River Thames that was polluted by raw waste. The people who drank this water were much more likely _______(get) cholera than those ______drank pure or boiled water.
Through Snow’s _________(tire) efforts, water companies began to sell clean water and the threat of cholera around the world saw a substantial decrease.However, cholera is still a problem. Each year, millions of people around the world get cholera and many die from it. Fortunately, we now know how to prevent cholera, thanks ______ the work of John Snow. Moreover, in his use of maps and statistics, Snow transformed the way scientists study diseases. ______ this reason, Snow is considered the father of modern epidemiology.
