This illness causes severe diarrhoea, dehydration, and even death. In the early 19th century, when an outbreak of cholera hit Europe, millions of people died from the disease. As a young doctor, John Snow became frustrated because no one knew how to prevent or treat cholera. In time, he rose to become a famous doctor, and even attended to Queen Victoria when she gave birth. However, he never lost his desire to destroy cholera once and for all.

One theory was that bad air caused the disease. Another was that cholera was caused by an infection from germs in food or water. Snow subscribed to the second theory. It was correct, but he still needed proof. Consequently, when an outbreak of cholera hit London in 1854, Snow began to investigate. He discovered that 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. Para.2 关于霍乱的蔓延方式，当时医生大体上有两种截然不同的看法。一种看法是空气污染引发，另一种看法是食物或饮用水中的细菌感染导致霍乱。斯诺赞同第二种看法。这一看法是正确的，但他仍需要证据。因此，1854年伦敦暴发霍乱时，斯诺便开始调查。他发现霍乱疫情在两条街道上尤为严重，十天内就有500多人死亡。他决心查明原因。 “一般说来” 宾语从句 表语从句 “同意;赞同” 宾语从句 “如此...以至于”，结果状语从句 “下定决心干某事” 细菌 Snow began by marking on a map the exact places where all those (who died) had lived.
