12、如何致人死亡的，当时有两种相对合理的看法， 斯诺对这两种看法比较感兴趣。第一种看法是霍乱病毒在空气中 1繁殖，它像一股危险的气体到处飘浮，直到找到受害者为止。第 1二种看法是人们是在吃饭时把这种病毒引入体内的。疾病从胃里 发作而迅速殃及全身，患者很快就会死亡。原文呈现CDJohn Snow suspected® that thesecond theory was correct but he needed evidence So when another outbreak hit London in 1854, he was ready to begin his enquiry

21、有喝从宽街水泵里抽上 来的水。看来水是罪魁祸首。接下来，约翰斯诺调查了这两条街的水源。他发现，水是从 河里来的，而河水被从伦敦排放的脏水污染了。他马上叫宽街上 惊慌失措的百姓拆掉水泵的把手，这样，水泵就用不成了。不久， 疫情就得到缓解。他证明了霍乱是由病菌而不是由气体传播的。原文呈现IIIIn another part of London, he found !i i supporting® evidence from two other deaths |i i that were linked to © the Broad Street !ii i outbreak. A

26、病菌。为了防止这种情况再度发生，约翰斯诺建议所有水源都要经过检测。供水公司得到指示，再也不能让人们接触被污染的水了。最 后，“霍乱王”被击败了。ffiSffiS把课文读通Step 1Pre-readingPlease match the words with their proper meanings.1. defeatA. to make a person or an animal healthyagain after an illness2 cureB a new or difficult task that tests sb.' sability and skill4 suspe
