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 U S 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.

Learning about the making and uses of past participle To form the past participle of a verb, add the ending -ed to the base form. (But note that many common verbs have irregular past participle forms.) ‎ The past participle is used in the following circumstances ‎◆After the auxiliary have in the perfect tense ‎ Has the radio been fixed yet?‎ ‎◆After a form of the auxiliary be in the passive voice The radio was fixed on Monday.‎ ‎◆After the verbs have and get with a causative meaning We had the radio fixed last week.‎ ‎◆As a passive participial adjective The recently fixed radio is broken again.‎ 过去分词作定语 ‎1 单个的过去分词作定语一般放在所修饰的名词之前；过去分词短语作定语一般要后置。 two married ‎ women a found umbrella a used stamp fallen leaves a novel written by Jim the letter sent to our boss ‎2 过去分词具有被动或完成的含义。 What’s the language spoken in Germany?‎ They decided to rebuild the damaged bridge.‎ ‎3 过去分词作定语常可扩展为一个定语从句。 He is fond of the food cooked (=which had been cooked) by your mother.‎ The report is the best of its kind ever written (=that has ever been written).‎ ‎4 有时通过一个形容词或数词加另一名词的ed形式构成复合形容词。 a three-legged desk a one-eyed dog an honest-faced man a warm-hearted lady ‎3. Discovering words and expressions ‎⑴ Doing exercises Turn to page 4 and go over exercises 1, 2 and 3. You can write your answers in the blanks right on the page.‎ ‎⑵ Making a list Make is a word which is so active that it forms numerous phrases.

OK?‎ Period5Using language Introduction Language is learned to be used in and for communication. So in this period after the warming up by looking and listening students will be listening and answering, discussing future jobs, reading a passage about Copernicus and copying its expressions, summing up theories and finally writing a letter to Copernicus. ‎ Objectives ‎■ To help students read the passage “Copernicus’ revolutionary theory on page 6‎ ‎■ To help students use the language by reading, listening, speaking and writing Procedures ‎1. Warming up by looking and listening Have you ever heard of a man named Qian Xuesen?‎ Qian Xuesen (1911- ), a native of Hangzhou, Zhejiang Province, went to the United States to study in 1935. In 1955 he returned to China, and in 1958 he joined the Communist Party.‎ He served successively as Director of the Institute of Mechanics under the Chinese Academy of Sciences, Vice-Minister of the No. 7 Ministry of the Machine-building Industry, Vice-Minister of the State Commission on Science, Technology and Industry for National Defence and Chairman of the China Association for Science and Technology. He was also elected alternate member of the Ninth through Twelfth CPC Central Committees. ‎ Qian played a leading role in the research, manufacture and testing of carrier rockets, guided missiles and satellites, thus making outstanding contributions to the development of China's aerospace industry.‎ ‎2. Listening and answering Turn to page 5. Listen to the tape in which Qian Xuesen is being talked about. Listen for information to answer the questions on listed on page 6.‎ ‎3. Reading and copying ‎ Now it’s time to read the text COPERNICUS’ REVOLUTIONARY THEORY and underline all the expressions useful to you at the same time. And after class write a short passage making use of the expressions underlined.‎ Expressions from COPERNICUS’ REVOLUTIONARY THEORY confuse one’s mind, make sense, in the sky, punish…for…, suggest an idea, make the world, for that reason, move backward, go forward in a loop, appear bright, think long and hard about…, find an answer, collect observations of…, use one’s knowledge to, show …to…, make change to…, place…at the center of…, publish one’s idea, be attacked by…, lie dying, reject one’s theory, be against one’s idea, build… on the base of…, replace the idea of…, fall to earth, create…as…, a direct link between…and…‎ ‎4. Summing up theories Next we shall do some scientific research: to sum up the two theories of the universe with the help of the text.‎ Before Copernicus’ theory Showing Copernicus’ theory The earth is the center of the universe. The earth is not the center of the universe.‎ God makes the world. God does not make the world.‎ ‎… …‎ ‎5. Writing a letter to Copernicus ‎(1)Reading about theories by Copernicus ‎ ‎1) The center of the Earth is not the center of the Universe, but only the center of the Earth's mass and of the lunar orbit.‎ ‎2) All the planets move along orbits whose center is the Sun, therefore the Sun is the center of the World. (Copernicus was never certain whether the Sun moved or not, claiming that ‎ the center of the World is 'in the Sun, or near it.')‎ ‎3) The distance between the Earth and the Sun, compared with the distance between the Earth and the fixed stars, is very small.‎ ‎4) The daytime movement of the Sun is only apparent, and represents the effect of a rotation that the Earth makes every 24 hours around its axis, always parallel to itself.‎ ‎5) The Earth (together with its Moon, and just like the other planets) moves around the Sun, so the movements that the Sun seems making (its apparent moving during daytime, and its annual moving through the Zodiac) are nothing else than effects of the Earth's real movements.‎ ‎6) These movements of the Earth and of the other planets around the Sun can explain the stations, and all the particular characteristics of the planets' movements.‎ ‎(2) Making a plan of writing a letter to Copernicus Beginning (self-introduction)‎ Paragraph 1 (reason 1 and evidence)‎ Paragraph 2 (reason 2 and evidence)‎ Summing up (persuasion )‎ ‎6. Closing down by making a debate To end our studies of Copernicus’ theories we shall make a debate whether the Sun is the center or the Earth is the center, of the universe. The class will be cut in two parts, one for Copernicus, the other against Copernicus. Now take five minutes to get necessary facts and arguments.‎ For Copernicus Against Copernicus ‎1) The center of the Earth is not the center of the Universe.‎ ‎2) All the planets move along orbits whose center is the Sun.‎ ‎3) The distance between the Earth and the Sun is very small.‎ ‎4) The daytime movement of the Sun is only apparent.‎ ‎5) The Earth moves around the Sun. 1) The center of the Earth is the center of the Universe.‎ ‎2) All the planets move along orbits whose center is the Earth.‎ ‎3) The distance between the Earth and the Sun is very big.‎ ‎4) The daytime movement of the Sun is just obscure.‎ ‎5) The Sun moves around the Earth.‎ 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.
