求翻译。。。
Educated people in the twenty-first century may find it hard to believe that two hundred years ago people did not link illness to problems in the environment. We all know that in London drinking polluted water caused many deaths from cholera.There was a clue to its cause because it always started in the poor neighbourhoods. Then it spread to the richer areas as the servants passed it on.Many doctors suspected that polluted water was to blame and clean water was the cure. John Snow`s investigation proved that the dirtier the water, the more severe the illness. So the government and the doctors concluded that water must be purified.They instructed people to remove the handles from pumps if the water was infected.Thus cholera was defeated in the end.
不要软件翻译的

我大概给你翻译一下吧，但做不到非常精致和信达雅。
在21世纪，受过教育的人们很难相信两百年前人们并不把疾病和环境问题联系起来。我们都知道，在伦敦，人们饮用受过污染的水导致了霍乱，而霍乱又导致了死亡。霍乱通常都是从贫穷的地方开始的，然后它会通过富人家的仆人们传播到富人居住的地方。许多医生都怀疑受过污染的水是引起霍乱的元凶而治疗方法则是让人们喝干净的水。John Snow的调查证实了，水越脏，霍乱越严重。于是政府和医生都知道了水应该被净化。他们指导人们把从被污染的水中抽水的水泵的把手移走。于是最后霍乱得以解决。

没什么事是百度解决不了的
