Section Ⅰ　Pre­reading (Warming Up & Reading)课前预习自测约翰·斯诺战胜“霍乱王”约翰·斯诺是伦敦一位著名的医生——他的确医术精湛，因而成为照料维多利亚女王的私人医生但他一想到要帮助那些得了霍乱的普通百姓时，他就感到很振奋霍乱在当时是最致命的疾病，人们既不知道它的病源，也不了解它的治疗方法每次暴发霍乱时，就有大批惊恐的老百姓病死约翰·斯诺想面对这个挑战，解决这个问题他知道，在找到病源之前，霍乱疫情是无法控制的斯诺对霍乱致人死地的两种推测都很感兴趣一种看法是霍乱病毒在空气中繁殖着，像一股危险的气体到处漂浮，直到找到病毒的受害者为止第二种看法是人们在吃饭的时候把这种病毒引入体内的病从胃里发作而迅速殃及全身，患者就会很快地死去斯诺推测第二种说法是正确的，但是他需要证据因此，在1854年伦敦再次暴发霍乱的时候，约翰·斯诺着手准备对此进行调研当霍乱在贫民区迅速蔓延的时候，约翰·斯洛就开始收集资料他发现特别在两条街道上霍乱流行得很严重，在10天之内就死去了500多人他决心要查明其原因首先，他在一张地图上标明了所有死者住过的地方这提供了一条说明霍乱起因的很有价值的线索。

许多死者是住在宽街的水泵附近(特别是这条街上16、37、38、40号)他发现有些住宅(如宽街上20号和21号以及剑桥街上的8号和9号)却无人死亡他以前没预料到这种情况，所有他决定深入调查他发现，这些人都在剑桥街7号的酒馆里打工，而酒馆为他们免费提供啤酒喝，因此他们没有喝从宽街水泵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情况他发现，水是从河里来的，而河水被伦敦排出的脏水污染了他马上叫宽街上惊慌失措的老百姓拆掉水泵的把手这样，水泵就用不成了不久，疫情就开始得到缓解他证明了，霍乱是由病菌而不是由气团传播的在伦敦的另一个地区，他从两个与宽街暴发的霍乱有关联的死亡病例中发现了有力的证据有一位妇女是从宽街搬过来的，她特别喜欢那里的水，每天都要派人从水泵打水运到家里来她和她的女儿喝了这种水，都得了霍乱而死去有了这个特别的证据，约翰·斯诺就能够肯定地宣布，这种被污染了的水携带着病菌为了防止这种情况的再度发生，约翰·斯诺建议所有水源都要经过检测自来水公司也接到指令，不能再让人们接触被污染的水了最终，“霍乱王”被击败了课堂合作探究1.What do you know_about infectious diseases？(教材P1)你对传染性疾病了解多少？know about/of 了解……情况(消息)①I strongly recommend Peking University to you because it_is_well_known_for its Department of Chinese.我强烈向你推荐北京大学，因为它以中文系出名。
