1、Section 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

2、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

3、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

4、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)I 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

23、n nature, he develops an idea, called a theory or hypothesis， about what is happening. Then he does an experiment to test his theory. If the results are as expected, then the experiment proves the hypothesis which makes it more likely that the theory is correct. If the experiment fails and the resul

24、ts are not as expected, then the scientist must come up with a new theory that he can test.In ancient times great thinkers came up with complicated theories to explain nature, but they did not always prove them by experiment. For example, the great Greek thinker Aristotle, had a theory that heavy ob

25、jects would fall faster than light objects. People believed this until the scientist Galileo performed an experiment and found it was wrong.Heres an experiment that you can use to prove or disprove a commonsense theory：Step 1: Get an empty bottle with a small neck. A diameter of 1/2 inch should be i

26、deal.Step 2: Cut a sheet of paper to a square 5 inches on each side.Step 3: Crumple the paper into a tight wad.Step 4: Lay the bottle on its side and place the paper so it lies loosely in the neck of the bottle.Construct a theory about what will happen if you put your mouth about a half inch from th

27、e neck of the bottle and blow hard towards it. A commonsense theory might be that the wad would be blown into the bottle by the force of the breath. Now do your experiment to see what really happens.If your theory was that the wad would be blown by the force of the air into the bottle, the experimen

28、t gave you unexpected results. In most cases the wad is blown out of the neck of the bottle in the opposite direction. A new theory might be that the air being blown into the bottle creates a whirlwind of air currents in the closed space which push the wad out.篇章导读：本文是一篇说明文。介绍了怎样用简单的四步实验法来验证一个常识理论是否

29、正确。1The writer mentions Aristotles theory to show _.Ahe was a great thinker in ancient timesBhe was less successful than GalileoCobjects of different weights fall at the same speedDexperiments are necessary to support theories答案：D推理判断题。根据第二段的内容，特别是“.

30、fall faster than light objects.
