cholera. Ask some students to put their answers in the chart. Paragraph Stages General ideas 1 Find a problem The causes of cholera 2 Make up a question The correct or possible theory 3 Think of a method Collect data on where people were ill and died and where they got their water 4 Collect results Plot information on a map to find out where people died or did not die 5 Analyse the results Analyse the water to see if that is the cause of the illness 6 Repeat if necessary Find other evidences to confirm his conclusion 7 Make a conclusion The polluted dirty source of drinking water was to blame for the cause of the London cholera T: Now class. Can you tell me what style of the passage belongs to? S1: I think it is a report. T: Here are three pieces of writing. They belong to different writing styles. Now read and find out what style each piece belongs to. Show the chart and three pieces of writing on the screen. Report Description Creative writing Formal language with few adjectives Vivid use of words with similes and metaphors Vivid use of language and more informal style No speech except quotations No speech except to help the description Speech to show feelings, reactions etc. Not emotional Emotional to describe atmosphere Emotional to describe feelings Only one main character No characters May have several characters Factual Not factual but imaginative Imaginative but can be based on fact Structural according to experimental method Not structured Beginning, middle, end Past tense and passive voice Past tense Past tense Making Way Once Goethe(歌德 ), the great German poet， was walking in a park. He was thinking about something when he noticed he came to a very, very narrow road. Just at that time, a young man came towards him from the other end of the road. It was too narrow for both of them to pass through at the same time. They stopped and looked at each other for a while. Then the young man said rudely， “I never make way for a fool.” But Goethe smiled and said, “I always do.” Then he turned back quickly and walked towards the end of the road. Weather Report Here‟s the weather report for the next 24 hours. Beijing will be fine with the temperature from 4 to 13. Tokyo will be fine too and cloudy later in the day. The lowest temperature is l to 8. London will be rainy and windy later in the day. The highest temperature is 8 and the lowest is 4. New York will be sunny and cloudy later in the day. The temperature is 13 to 19. Heartbeating Put your hand to the left side of your chest. Try to feel your heartbeating. The heart takes a little rest after each pump or beat. In boys or girls of your age, heart beats about 90 times a minute. A grownup‟s heart beats about 70 or 80 times a minute. But the heartbeat is different in the same person at different times. For example, the heart beats faster during exercise. It is also faster when a person is angry, scared, or excited. During sleep, the heartbeat slows down. Sample answers: S1: I think the first piece “Making A Way” is in a style of creative writing. The second piece belongs to a description style. The third piece belongs to a report style. T: Very good. Now let‟s return to our text. Who can tell me the main idea of this passage? S2: I can. Clearly it tells us how John Snow defeated the disease cholera by doing scientific research. StepⅥ Homework 1.

Sample versions: S1: I‟ll have a try. John Snow was a very famous doctor in London in 19th century. At the time he lived, cholera was the most frightening disease, which killed many thousands of people in the industrial cities of England. Nobody knew the cause of the disease. John Snow believed that cholera was caused by drinking polluted water. He believed that when dirty water from the toilet and drinking water were mixed, it was possible for the illness to be passed from one person to the next. In 1854, he was able to prove that his theory was correct. To do this he approached the problem in a systematic way. He found an outbreak of cholera and studied its effects on a small neighborhood. He gathered information about the drinking habits of the people and used them to justify his theory. He is important because he was the first person to gather information scientifically about a disease in order to find its cause. S2: OK. I‟d like to retell Snow‟s work in the order of the stages. We know there were seven stages in his research. First Snow, as well as other doctors could not find the cause of the cholera, nor the cure for it. He got interested in two theories. 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. He believed in the second theory. So he collected much information to prove it. He did a lot of resea。
