Then they will be helped to read a narration about John Snow fighting cholera. They shall learn the text by reading and underlining, reading to finish the table, making a diagram of the text JOHN SNOW DEFEATS “KING CHOLERA” and retelling the text in their own words with the help of the diagram above. ‎ Objectives ■ To help students learn to describe people ‎ ■ To help students learn to read a narration about John Snow ‎ ■ To help students better understand “Great scientists”‎ ■ To help students learn to use some important words and expressions ■ To help students identify examples of “The Past Participle (1) as the Predicative & attribute” in the text Focus Words conclude, analyze, repeat, defeat, attend, expose, cure, control, absorb, pump, blame, handle, announce, instruct, contribute, spin, reject Expressions ‎ put forward, draw a conclusion, in addition, link…to…, apart from…, be strict with…, lead to, make sense, point of view Patterns ‎ But he became inspired when he thought about helping ordinary people…‎ So many thousands of terrified people died every time there was an outbreak.‎ He got interested in two theories explaining how cholera killed people. ‎ He determined to find out why.‎ It seemed the water was to blame. ‎ Aids Multimedia facilities, tape-recorder, photos, diagrams ‎ Procedures ‎1. Warming up ‎ ‎⑴Warming up by defining Good morning, class. I am glad to see you on this special day, the day when you become a senior two student. I am happy to be your teacher of English.‎ Today we are going to read about a certain scientist. But first let’s define the word “scientist”. What is a scientist?‎ Scientist A scientist is a person who works in science, trying to understand how the universe or other things work.‎ Scientists can work in different areas of science. Here are some examples: Those that study physics are physicists. Those that study chemistry are chemists. Those that study biology are biologists.‎ ‎⑵Warming up by asking and answering questions about science To begin with, work in groups of four and find out as many scientists as possible and their contributions. They can be both Chinese and foreign scientists, living or dead.‎ Scientists Contributions Madame Curie radium/ radioactivity Sir Isaac Newton the Theory of Gravity Albert Einstein the secrets of the atom and of the universe the Theory of Relativity Thomas Einstein electric light bulb Charles Darwin the Theory of Evolution The Origin of Species Stephen Hawking black holes A Brief History of Time Zhang Heng the earliest seismograph Yuan Longping Agriculture ‎(Father of Hybrid Rice) ‎ Qian Xuesen China’s aerospace ‎ ‎(Father of the Chinese space programme)‎ Alexander Fleming penicillin Alexander Graham Bell first telephone call John Baird ‎ invent television Ray Tomlinson first e-mail message Galileo Galilei his famous Leaning Tower of Pisa experiment Benjamin Franklin famous kite experiment Nicolaus Copernicus astronomy curriculum ‎⑶Warming up by talking about top honor for two Chinese scientists Hello, everyone. Nice meeting you here. You are now a senior two student. Some of you will be a scientist in the future. But have you ever heard that Yuan Longping, director-general of the China National Hybrid Rice Research and Development Centre in central China's Hunan Province and Bai Chunli, vice-president of the Chinese Academy of Sciences in Beijing were formally introduced to the academy on April 28, 2007 at a global meeting of US academy members and foreign associates.‎ ‎●Yuan Longping, director-general of the China National Hybrid Rice Research and Development Centre in Central China's Hunan Province and Bai Chunli, vice-president of the Chinese Academy of ‎ Sciences in Beijing were formally introduced to the academy last Saturday at a global meeting of US academy members and foreign associates. ‎ Yuan, 77, dubbed the "father of hybrid rice" for his extraordinary contributions toward developing high-yield rice, is a household name in China. ‎ With more than half of China's paddy fields growing Yuan's rice, his scientific breakthrough has fed millions of people in the world's most populous country. ‎ His "super rice" has also been introduced to more than 20 other countries. ‎ ‎●Bai, 52, is considered to be a leading expert in China's molecular nanostructure and nanotechnology studies. ‎ ‎"I think the fast development of Chinese science has drawn increased attention from the US academy," Bai said in an interview with China Daily last year shortly after he was elected. ‎ ‎2. Pre-reading by sharing opinions on proving a new idea Anybody might come out with a new idea. But how do we prove it in scientific research? How many stages are there in examining a new idea in scientific research? What are they?‎ Now look at the blackboard to learn about the seven stages put in an order.‎ Find a problem→ Make up a question→ Think of a method→ Collect results→ ‎ Analyse the results→ Draw a conclusion→ Repeat if necessary Could you give an example to illustrate the seven stages?‎ ‎3. Reading ‎⑴Listening and reading aloud To know more about scientific research, turn to page 2 and read aloud the article. Try at the same time to locate the information to complete the form below.‎ Who When What How Result John Snow ‎1854‎ helping ordinary people exposed to cholera Examining the source of all water supplies and finding new methods of dealing with polluted waster ‎“King Cholera”defeated ‎⑵Reading and underlining Now you are asked to go over the text the second time, looking for the expressions within the passage and underlining them at the same time. After class copy them into your Expression Notebook and write a short passage of your own making use of the expressions.‎ Expressions from JOHN SNOW DEFEATS “KING CHOLERA”‎ ease the birth of…, become inspired, find the cause, multiply in the air, without reason, a cloud of gas, float around…, find one’s victims, absorb… into… with the meals, attack the body, test the theories, spread through…, gather the information, mark…on the map, give a clue about…, drink water from…, …be to blame, remove…from…, slow down, be spread by…, in addition, be linked to…, move away from…, deliver…from…to…, die of…, with certainty, prevent…from…, deal with…, instruct…to ‎⑶Reading to finish the table below Read the text again to decide on the type of writing and summary of JOHN SNOW DEFEATS “KING CHOLERA”.‎ Type of writing This is a piece of narrative writing.‎ Main idea of the passage It tells about John Snow and his fight against “King Cholera”.‎ Topic sentence of 1st paragraph John Snow was a well-known doctor in London.‎ Topic sentence of 2nd paragraph ‎ He got interested in two theories explaining how cholera killed people.‎ Topic sentence of 3rd paragraph He believed in the second theory but needed to prove he was correct. ‎ Topic sentence of 4th paragraph He looked into the sources of the water. ‎ Topic sentence of 5th paragraph John Snow had shown that cholera was spread by germs.‎ Topic sentence of 6th paragraph Finally “King Cholera” was defeated.‎ ‎⑷Making a diagram of the text JOHN SNOW DEFEATS “KING CHOLERA”‎ Two theories: cholera absorbed through air; cholera absorbed with meals Para. 2‎ John Snow helping people exposed to cholera Para. 1‎ John Snow for 2nd theory Para. 3‎ John Snow finding polluted water spreading germs of cholera Para. 5‎ John Snow looking for cholera in the water Para. 4‎ King Cholera defeated by John Snow Para. 6‎ ‎⑸Retelling the text in your own words with the help of the diagram above Retelling can be useful, for it both strengthen ones’ learning of the vocabulary, the structure, and gives one a wonderful chance to practice speaking English. ‎ ‎4.
