In the city of London about 150 years ago, many people started to get very sick. The sickness they had was called "cholera(霍乱)". The disease frightened Londoners because nobody knew how to stop it. At that time, most doctors thought that people got cholera from breathing in polluted air. They told them to open their windows and breathe in fresh air as much as possible. However, this advice did not seem to work as more and more people got the disease.
John Snow had a different idea. He thought that cholera might spread through the water that people were drinking. Maybe polluted water was making everyone sick. At first, nobody paid much attention to him. So he thought of a plan to test his idea about the polluted water. He went to different neighborhoods in London and tested their water. It was just as he had thought! The neighborhoods with the cleanest water had the fewest sick people. The places with the dirtiest water had the greatest number of sick people. This proved his idea that cholera was spread through dirty water.
John Snow showed the results of his study to the mayor of London and the other doctors. They realized that he was right. After that, all over London people stopped drinking water that might be polluted. John Snow may not be as famous as Superman, but he is really a hero.
