Reading-I----skimming (2m) Skimming: answer the following questions: What are the two theories John Snow got interested in? What did John Snow’ experience show? How to prevent the disease happening again?

9 Keys: 1.The two theories are : The first suggested that cholera multiplied in the air without reason. The second suggested that people absorbed this disease into their bodies with their meals. 2.John Snow had shown that cholera was spread by germs and not in a cloud of gas. 3.To prevent this from happening again, John Snow suggested that the source of all water supplies be examined and new methods of dealing with polluted water be found.

10 Scientific Report by John Snow
Reading-II----scanning (3m) Scientific Report by John Snow The problem The cause Idea 1: Idea 2:people absorbed the disease_________________. The method The results Idea 1 or 2?why? The conclusion the cause of the serious disease of cholera.

11 Reading-III----detailed reading (2m)
Read the passage again, and then find out the difficult or key sentences with the partner.

12 1. But he became inspired when he thought about helping ordinary people exposed to cholera.
In the case of an infectious disease it means not taking care to stop its spread.

13 2.He got interested in the two theories explaining how cholera killed people.
This means that he began to find out about both theories.

14 3. It seemed the water was to blame.
The sentence means Probably it was the water that caused the illness.

15 Discussion: Discuss the following questions in groups of four.
Discussion (4m) Discussion: Discuss the following questions in groups of four. Cholera was a 19th century disease. What disease do you think is similar to cholera today? 1. John Snow believed Idea 2 was right. How did he finally prove it? 2. Do you think John Snow would have solved this problem with- out the map? Give a reason. 3.

16 Keys Two diseases, which are similar today, are SARS and AIDS because they are both very serious, have an unknown cause and public health care to solve them. 1. 2. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.

17 3. No. The map helped John Snow organise his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.

39 Discovery (2m) Students try to find some rules about the Past Participle as the Attribute and Predicative.

40 Grammar 一、过去分词作定语 1、单个的过去分词作定语时一般兼有被动和完成的意义，常作前置定语。
eg：a lost animal 一只迷路的动物 a used stamp 一枚用过的邮票 an injured finger 一个受伤的手指 a broken coin 一枚破损的硬币 a lighted candle 一支点燃的蜡烛 注意：过去分词作定语时，有时只有被动意义。 e.g.：spoken English 英语口语 written exercises 书面练习

45 二、过去分词作表语 1、过去分词作表语，表示主语的特点或所处的状态，其前的系动词有包括be在内的多种形式。 e.g.：Everyone present is very inspired at his speech． 听了他的发言，在场的所有人都很振奋。 You seem frightened. 你似乎受了惊吓。

46 2、过去分词作表语，构成的系表结构与被动语态的区别：
过去分词作表语，强调主语的特点或所处的状态；而被动语态中，主语是动词所表示动作的承受者。 e.g.：This shop is now closed． 这家商店现在已经关门了。(状态) This shop is closed at 6 pm everyday． 这家商店每天6点关门。(动作）
