概括一下John snow defeats “king cholera” ？
推荐回答（3个）
一句话概括：有名医生John Snow 是如何通过考察、分析和探究的科学方法，发现并控制“霍乱”这种传染疾病的。
简介：John Snow 是伦敦有名的医生，而那时霍乱是最致命的疾病。其致病原因和治疗手段都尚不明确。每次疫情暴发都有上千的人们死亡。当时，解释霍乱是如何导致人们死亡的说法有两种。John Snow 比较认同疾病是随餐进入人体的，但他缺乏证据。当疾病迅速蔓延到他可怜的邻居时，他开始着手收集这些信息。他在地图上标出死去人们曾居住的地方。这幅图为疾病的起因提供了重要的线索。Broad街的管道流出的水貌似有问题。更重要的发现是这水来自被伦敦污染后的河流。在调查了另外两个事件后，John Snow明确宣布被污染的河流就是传播疾病的元凶，并建议检测所有的水源供给。最终霍乱被打败了。
是概括课文大意吗
John Snow, a famous doctor and expert, succeeded in defeating King Cholera in a scientific way. Cholera was a deadly disease and had attacked London twice in the 1850s.
The main idea of this passage is that John Snow found out the cause of the disease called colera which was a deadly disease in London in the 19th century. With Snow's great efforts, the disease was finally under control.
