Unit 1 Great scientistsBrief Statements Based on This UnitThis unit centers on Great scientists, including some scientists both at home and abroad like John Snow and Copernicus.The students should be encouraged to practise talking about these scientists.The whole unit can be divided into seven parts: warming up, reading, listening and speaking,In warming up, there is a quiz for the students to do, which will arouse the students’ interest in knowing about the famous scientists and help the students to know science is very important in our daily life.Group discussion and brainstorming will be used in this period to help the students to communicate with each other using their previous knowledge.In the reading passage, the students will learn about John Snow, who defeats“King Cholera”, and get a general idea about how to examine a new scientific idea.This will help the students to form their own attitude towards science.In learning about language, the students are encouraged to learn the following words and expressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyze repeat, defeat, attend, expose, cure, control, absorb, severe, valuable, blame, immediately, handle, announce, instruct, virus, construction, contribute, positive, movement, backward, complete, enthusiastic, spin, reject, view, steam engine, put forward, draw a conclusion, in addition, link...to..., be strict with, lead to, make sense, point of view.While practising using the language, the students will learn about Copernicus’ RevolutionaryIn listening and speaking, more chances will be given to the students to learn about other scientists and their spirit.The students are encouraged to make up their mind to make contributions to science.The students will be asked to write a letter to Copernicus on the basis of the understanding of the text.The letters are sure to be full of imagination and creativity.Assessment will help the students to look back what they have learned and focus on the difficult and important points.Period 1Period 2Period 3 Listening andPeriod 4Period 6Period 7Knowledge aims:Key words in this unit: engine, characteristic, radium, theory,

encourage the students to learn about some great scientists and their great acand how science helps to improve our society and change our life.Meanwhile, inspire the students to learn from the scientists and form their positive attitude towards science.Period 1 Welcome to the UnitThe General Idea of This PeriodThe uni t centers on“great scientists”.This is the first period of this unit.During this period, the students should be encouraged to give their previous knowledge of some of the famous scientists, participate in the activities in class and try to get more information from the discussion.They will take part in different forms of activities, including pair work, group work, competition, and quiz.Group competition will be carried out all through the class.Words and expressions in this unit will help the students to talk about the topic“great scientists”.So at the beginning of this period, the teacher should spend some time training the students to read them and help the students pronounce them correctly.The students are encouraged to learn the new words in groups by themselves, using dictionaries and other reference books.Then more time should be given to the students to get familiar with the words and stly, several sentences will be given to the students to help them to know how to use some of the phrases.This unit is about“great scientists”, so from the very beginning, the teacher canstudents brainstorm something about great scientists.The students are free to say anything that they know.The students will be quite interested in this topic.This activity gives the students a chance to express their feelings about their favorite scientist.At the same time, this activity can stir the students’ enthusiasm in science.Then the teacher can have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists.Later the students will be divided into several groups, describe one of the greatAfter that, the students will feel comfortable to do the quiz in the text.The students shouldMeanwhile, the students’ interest in scientists and science should be cultivated.So twoThe post-class activities are designed to arouse the students’ interest in science and encourage them to“DIY—do it yourself” in their daily life if they have some doubt in some areas.Teaching Important PointsHave the students discuss great scientists.Encourage the students to hold their views about their future career.Understand and learn the following words and expressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyse, repeat, defeat, attend, expose, cure, control, absorb, severe, valuable, blame, immediately, handle,

Darwin published The Origin of Species by Means of Natural Selection in 1859, sparking decades of contentious debate which ultimately led to the universal scientific recog nition of Darwin’s thesis.In later years, he developed his ideas further in monographs on different types of plant and animal life.Notes:Shrewsbury: 什鲁斯伯里[英国英格兰西部城市physician: 内科医生 (注意区分physicist, 物理学家revolutionary: 创新的HMS: （英国）皇家海军舰船 (Her/His Mtreatises: 论文2.Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford, England.His parents’ house was in north London, but during the Second World War Oxford was considered a safer place to have babies.When he was eight, his family moved to St Albans, a town about 20 miles north of London.At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father’s old college. Stephen wanted to do Mathematics, although his father would have preferred medicine.Mathematics was not available at University College, so he did Physics instead.After three years and not very much work he was awarded a first class honours degree in Natural Science.Stephen then went on to Cambridge to do research in Cosmology, there being no-one working in that area in Oxford at the time.His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge.After gaining his Ph.D.he became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College.After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics.The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for the University.It was first held by Isaac Barrow, and then in 1663 by Isaac Newton.Stephen Hawking has worked on the basic laws which govern the universe.With Roger Penrose he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes.These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century.One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear.Another conjecture is that the universe has no edge or boundary in imaginary time.This would imply that the way the universe began was completely determined by the laws ofHis many publications include The Large Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel.Stephen Hawking has two popular books published: his best seller A Brief History of Time, and his later book, BlackProfessor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and was made a Companion of Honour in 1989.He is the recipient of many awards, medals and prizes and is a Fellow of The Royal Society anStephen Hawking continues to combine family life (he has three children and one grandchild), and his research into theoretical physics together with an extensive programme of travel and public lectures.3.Humphry Davy, a woodcarver’s son, was born in Penzance in 1778. After being educated in Truro, Davy was apprenticed to a Penzance surgeon.In 1797 he took up chemistry and was taken on by Thomas Beddoes, as an assistant at his Medical Pneumatic Institution in Bristol.Here he experimented with various new gases and discovered the anesthetic effect of laughing gas (nitrous oxide).Davy published details of his research in his book Researches, Chemical and Philosophical (1799).This led to Davy being appointed as a lecturer at the Royal Institution.He was a talentedIn 1806 Davy published On Some Chemical Agencies of Electricity. The following year he discovered that the alkalis and alkaline earths are compound substances formed by oxygen united with metallic bases.He also used electrolysis to discover new metals such as potassium, sodium,Davy was now considered to be Britain’s leading scientist and in 1812 was knight ed by George Ⅲ.With his assistant, Michael Faraday, Davy travelled abroad investigating his theory ofIn 1815 Humphry Davy invented a safety lamp for use in gassy coalmines, allowing deep coal seams to be mined despite the presence of firedamp (methane).This led to some controversy as George Stephenson, working in a colliery near Newcastle, also produced a safety lamp thatOne of Davy’s most important contributions to history was that he encourage manufacturers to take a scientific approach to production.His discoveries in chemistry helped to improve several industries including agriculture, mining and tanning.Sir Humphry Davy died in 1829.4.Leonardo da Vinci(b.1452, Vinci, Republic of Florence [now in Italy]—d.May 2, 1519, Cloux, Fr.), Italian painter, draftsman, sculptor, architect, and engineer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal.His Last Suppe (1495-1497) and Mona Lisa (1503-1506) are among the most widely popular and influential paintings of the Renaissance.His notebooks reveal a spirit of scientific inquiry and a mechanical inventiveness5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In 1891 she went to study in Paris University because at that time women were not admitted to universities in Poland.When she was studying in Paris, she lived a poor life, but she worked very hard.In 1895 she married Pierre Curie, and then they worked together on the research into radioactive matter.They discovered two kinds of radioactive matter—polonium and radium.In 1904 she and her husband were given the Nobel Prize for physics.In 1906 Pierre died, but Marie went on working.She received a second Nobel Prize for Chemistry in 1911.So she became the first scientist in the world to win two Nobel Prizes.6.James Watt: British engineer and inventor who made fundamental improvements in the steam engine, resulting in the modern, high-7.Gregor Mendel was an Austrian botanist and founder of the science of genetics.Through years of experiments with plants, chiefly garden peas, he discovered the principle of the inheritance8.Archimedes: Greek mathematician, engineer, and physicist.Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of buoyancy.9.Michael Faraday (September 22, 1791—August 25, 1867) was a British scientist(a physicist and chemist) who contributed significantly to the fields of electromagnetism and electrochemistry. He also invented the earliest form of the device that was to become the Bunsen burner, which is used almost universally in science laboratories asMichael Faraday was one of the great scientists in history.Some historians of science refer to him as the greatest experimentalist in the history of science.It was largely due to his efforts that electricity became a viable technology.The SI unit of capacitance, the farad(symbol F) is named after him.。

Unit 1 Great scientistsThe first period: Warming up and readingImportant points:Let students learn about some great scientists and their contributions.Get students to read the passage and know about John Snow and how he defeated “King Cholera” by using different reading skills.Difficult points:Develop students` reading ability and learn how to organize scientific research.Enable students to talk about great scientists and tell their stories.Step 1 Lead inHave a free talk with students: we have learned about many great people and some famous scientists and now look at the pictures of these great people: Isaac Newton, Albert Einstein, Stephen Hawking, Qian Xuesen, and tell their contributions.Discuss the following question in small groups: what qualities do you think a scientist should have?(persistent, determined, imaginative, careful, creative, clever, strict, patient,…… )Step 2 Warming up1. Ask students to have a discussion in pairs to try this quiz and find out who knows the most.Step 3 Pre-reading1. Do you know how to prove a new idea in scientific research? Discuss in small groups the stages in setting out a newsupporting evidence→Draw a conclusion)2. What do you know about infectious diseases? What do you know about cholera?(Infectious diseases can spread easily. They may do great harm to people. AIDS and SARS are infectious diseases. They are difficult to cure.)(Cholera(霍乱) infects people`s intestines(肠), causing diarrhea(腹泻), vomiting(呕吐) and leg cramps(腿部痉挛). The most common cause of cholera is that people eat or drink water polluted by the bacteria(细菌). A severe case can lead to death without immediate treatment.)Step 4 Reading1. Skimming: ask students to skim the text and try to find the main idea of the passage as they can.(The main idea: How John Snow collected, analyzed the data and found the cause of the disease and solved it.)2. Scanning: ask them to try to get detailed information and then choose the correct answers after reading the passage.1). John Snow became inspired when _______.A. he became a well-known doctor in LondonB. he attended Queen Victorian to ease the birth of her babiesC. he thought about helping ordinary people exposed to choleraD. he found the cause of cholera and defeated “King Cholera”2). The reason why John Snow used the map in his research was that with its help ______. A. he would not lose his wayC. he could find out what caused the outbreak of choleraD. he could find out how many people died3). Why did such houses as 20 and 21 Broad Street and Cambridge Street have no deaths? Because ________.A. people there were given free beer and they had not drunk the water from Broad Street pumpB. people there had known that the water was polluted by the dirty water from LondonC. the disease began to slow down in Broad Street and Cambridge StreetD. people in these families were much stronger than those near the Broad Street pump4). The following measures should be taken to prevent cholera except _______.A. always drinking beerB. instructing the water companies not to expose people to polluted water any moreC. examine all water suppliesD. finding new methods of dealing with polluted water.5). What made John Snow find the cause of cholera?A. Queen Victoria`s orderB. his wife`s deathC. Kindness, carefulness and good observationD. Strong determination, patience and selfishness(The answers: CCAAC)4. Answer the questions:1). John Snow believed Idea 2 was right. How did he finally prove it?(He finally proved his idea because he found an outbreak that was clearly related to the Broad Street outbreak, collected information and was able to tie cases outside the area to polluted water.)2). Do you think John Snow would have solved this problem without the map?(No. The map helped John Snow organize 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.)3). Cholera was a 19th century disease. What disease do you think is similar to cholera today? Why?(Three diseases, which are similar today, are SARS, AIDS and bird flu, because they are serious, have unknown causes and need public health care to solve them.)5. Fill in the blanks:How did John Snow finally defeat cholera?As the disease spread quickly, John Snow began to gather information. He marked on a map where all the dead people had lived, analyzed all the evidence and found out the polluted water was the cause. Then he suggested that the source of all drinking water should be examined.根据课文内容填空：1. Encourage students to fill in the stages of a scientific experiment at the top of each paragraph. Ask students to look at each paragraph and its heading in turn. Get them to write down the evidence or approach John Snow used in that stage to fill in2. Begin a class discussion with students by asking them the following questions:What branch of science are you using to illustrate the stage of an experiment?Did these stages fit your branch of science?Is this an approach used in your science class when you do experiments?What differences are there (if any)?Do you think these differences (if there are any) are important?Do you think this approach would work for all scientific subjects?Step 6 Consolidation1. Ask students to complete the following without referring to the textbook, using the words and phrases from the reading passage.John Snow was a famous doctor in London. There was the most deadly disease called “King Cholera” of its day. Every time there was a(n) outbreak, many people died. John Snow wanted to face the challenge and solve this problem. He knew that it would never be controlled until its cause was found. At that time, there were two theories about cholera. The first suggested that cholera multiplied in the air. The second suggested that people absorbed this disease into their bodies with their meals. John Snow suspected the second theory was correct but he needed evidence. So he collected data to test the two theories. He marked on a map where all the dead people had lived and the map gave a valuable clue about the cause of the disease. It seemed that the water was to blame. Next, John Snow looked into the source of the water for these streets. He found two other deaths in another part of London that were linked to the Broad Street outbreak. With enough evidence, he announced with certainty that polluted water carried the virus of cholera.2. let students retell the reading passage in their own words.Step 7 HomeworkLearn the useful words and expressions by heart.Read the reading passage again and try to say or write something about how John Snow defeated “King Cholera”.The second period: Learning about language: Important language pointsImportant points:1. Enable students to grasp the usage of such important new words and expressions as conclude, defeat, attend, cure, challenge, suspect, blame, pollute, handle, announce, put forward, draw a conclusion, expose… to, link….to….2. Get students to master the following sentence patterns:So many thousands of terrified people died every time there was an outbreak.It seemed that the water was to blame.To prevent this from happening again, John Snow suggested the source of all the water supplies be examined.Difficult points:Let students learn the usage of the words: attend and blame.Get students to learn and understand some long and difficult sentences.Knowledge aims:Some new words and expressions: characteristic, radium, painter, scientific, conclude, conclusion, analyze, defeat, expert, attend, physician, expose, cure, challenge, victim, absorb, suspect, enquiry, neighbour, severe, pump, foresee, blame, pollute, handle, link, announce, instruct, construct, construction, contribute, put forward, draw a conclusion, expose.. to, link…to, apart fromLet students learn the following important sentence patterns:But he became inspired when he thought about helping ordinary people exposed to cholera.

the scientists and form their positive attitude towards science.Period 1Welcome to the UnitThe General Idea of This PeriodThe un it centers on“great scientists”.This is the first period of this unit.During this period, the students should be encouraged to give their previous knowledge of some of the famous scientists, participate in the activities in class and try to get more information from the discussion.They will take part in different forms of activities, including pair work, group work, competition, and quiz.Group competition will be carried out all through the class.Words and expressions in this unit will help the students to talk about the topic“great scientists”.So at the beginning of this period, the teacher should spend some time training the students to read them and help the students pronounce them correctly.The students are encouraged to learn the new words in groups by themselves, using dictionaries and other reference books.Then more time should be given to the students to get familiar with the words and stly, several sentences will be given to the students to help them to know how to use some of the phrases.This unit is about“great scientists”, so from the very beginning, the teacher cantalk about their dreams in the future.Then the teacher can let the students brainstorm something about great scientists.The students are free to say anything that they know.The students will be quite interested in this topic.This activity gives the students a chance to express their feelings about their favorite scientist.At the same time, this activity can stir the students’ enthusiasm in science.Then the teacher can have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists.Later the students will be divided into several groups, describe one of the greatstudents guess who he or she is talking about.In this way, the students should learn to organize their own sentencesAfter that, the students will feel comfortable to do the quiz in the text.The students should be encouraged toMeanwhile, the students’ interest in scientists and science should be cultivated.So two topic discussionThe post-class activities are designed to arouse the students’ interest in science and encourage them to“DIY—do it yourself” in their daily life if they

Darwin published The Origin of Species by Means of Natural Selection in 1859, sparking decades of contentious debate which ultimately led to the universal scientif ic recognition of Darwin’s thesis.In later years, he developed his ideas further in monographs on different types of plant and animal life.Notes:Shrewsbury: 什鲁斯伯里[英国英格兰西部城市physician: 内科医生(注意区分physicist, 物理学家revolutionary: 创新的HMS: （英国）皇家海军舰船(Htreatises: 论文2.Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford, England.His parents’ house was in north London, but during the Second World War Oxford was considered a safer place to have babies.When he was eight, his family moved to St Albans, a town about 20 miles north of London.At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father’s old college. Stephen wanted to do Mathematics, although his father would have preferred medicine.Mathematics was not available at University College, so he did Physics instead.After three years and not very much work he was awarded a first class honours degree in Natural Science.Stephen then went on to Cambridge to do research in Cosmology, there being no-one working in that area in Oxford at the time.His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge.After gaining his Ph.D.he became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College.After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics.The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for the University.It was first held by Isaac Barrow, and then in 1663 by Isaac Newton.Stephen Hawking has worked on the basic laws which govern the universe.With Roger Penrose he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes.These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century.One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear.Another conjecture is that the universe has no edge or boundary in imaginary time.ThisHis many publications include The Large Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel.Stephen Hawking has two popular books published: his best seller A Brief History of Time, and his later book, Black Holes and BabyProfessor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and was made a Companion of Honour in 1989.He is the recipient of many awards, medals and prizes and is a Fellow of The Royal SocietyStephen Hawking continues to combine family life (he has three children and one grandchild), and his research into theoretical physics together with an extensive programme of travel and public lectures.3.Humphry Davy, a woodcarver’s son, was born in Penzance in 1778. After being educated in Truro, Davy was apprenticed to a Penzance surgeon.In 1797 he took up chemistry and was taken on by Thomas Beddoes, as an assistant at his Medical Pneumatic Institution in Bristol.Here he experimented with various new gases and discovered the anesthetic effect of laughing gas (nitrous oxide).Davy published details of his research in his book Researches, Chemical and Philosophical (1799).This led to Davy being appointed as a lecturer at the Royal Institution.He was a talented teacher and his lectures attractedIn 1806 Davy published On Some Chemical Agencies of Electricity. The following year he discovered that the alkalis and alkaline earths are compound substances formed by oxygen united with metallic bases.He also used electrolysis to discover new metals such as potassium, sodium, barium, strontium, calcium andDavy was now considered to be Britain’s leading scientist and in 1812 wa s knighted by Georg e Ⅲ.With hisIn 1815 Humphry Davy invented a safety lamp for use in gassy coalmines, allowing deep coal seams to be mined despite the presence of firedamp (methane).This led to some controversy as George Stephenson, working in a colliery near Newcastle, also produced a safety lamp that year.Both men claimed that they were first to come upOne of Davy’s most important cont ributions to history was that he encourage manufacturers to take a scientific approach to production.His discoveries in chemistry helped to improve several industries including agriculture, mining and tanning.Sir Humphry Davy died in 1829.4.Leonardo da Vinci(b.1452, Vinci, Republic of Florence [now in Italy]—d.May 2, 1519, Cloux, Fr.), Italian painter, draftsman, sculptor, architect, and engineer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal.His Last Suppe (1495-1497) and Mona Lisa (1503-1506) are among the most widely popular and influential paintings of the Renaissance.His notebooks reveal a spirit of scientific5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In 1891 she went to study in Paris University because at that time women were not admitted to universities in Poland.When she was studying in Paris, she lived a poor life, but she worked very hard.In 1895 she married Pierre Curie, and then they worked together on the research into radioactive matter.They discovered two kinds of radioactive matter—polonium and radium.In 1904 she and her husband were given the Nobel Prize for physics.In 1906 Pierre died, but Marie went on working.She received a second Nobel Prize for Chemistry in 1911.So she became the first scientist in the world to win two Nobel Prizes.6.James Watt: British engineer and inventor who made fundamental improvements in the steam engine, resulting in the modern, high-7.Gregor Mendel was an Austrian botanist and founder of the science of genetics.Through years of experiments with plants, chiefly garden peas, he discovered the principle of the inheritance of characteristics8.Archimedes: Greek mathematician, engineer, and physicist.Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of buoyancy.9.Michael Faraday (September 22, 1791—August 25, 1867) was a British scientist(a physicist and chemist) who contributed significantly to the fields of electromagnetism and electrochemistry. He also invented the earliest form of the device that was to become the Bunsen burner, which is used almost universally in science laboratoriesMichael Faraday was one of the great scientists in history.Some historians of science refer to him as the greatest experimentalist in the history of science.It was largely due to his efforts that electricity became a viable technology.The SI unit of capacitance, the farad(symbol F) is named after him.。

Nice to see you on this special day, the day when you become a senior two grader. I am happy to be with you helping you with your English. Today we are to read about a ce rtain scientist. But first let’s define the word “scientist”. What is a 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.Step II 头脑风暴Ask the students to try the quiz and find out who knows the most.T: There are some great scientific achievements that have changed the world. Can you name some of them? What kind of role do they play in the field of science? Do these achievements have anything in common? Match the inventions with their inventors below before you answer all these questions.1.Archimedes, Ancient Greek (287-212 BC), a mathematician.2. Charles Darwin, Britain (1808-1882). The name of the book is Origin of Species.3. Thomas Newcomen, British (1663-1729), an inventor of steam engine.4. Gregor Mendel, Czech, a botanist and geneticist.5. Marie Curie, Polish and French, a chemist and physicist.6. Thomas Edison, American, an inventor.7. Leonardo da Vinci, Italian, an artist.8. Sir Humphry Davy, British, an inventor and chemist.9. Zhang Heng, ancient China, an inventor.10. Stepper Hawking, British, a physicist.II. Pre-reading 预读Step IGet the students to discuss the questions on page 1 with their partners. Then ask the students to report their work. Encourage the students to express their different opinions.1.What do you know about infectious diseases?Infectious diseases can be spread to other people. They have an unknown cause and need public health care to solve them. People may be exposed to infectious disease, so may animals, such as bird flu，AIDS, SARS are infectious diseases. Infectious diseases are difficult to cure.2.What do you know about cholera?Cholera is the illness caused by a bacterium called Vibrio cholerae. It infects people’s intestines(肠), causing diarrhea and leg cramps (抽筋).The most common cause of cholera is by someone eating food or drinking water that has been contaminated(污染) with the bacteria. Cholera can be mild(不严重的) or even without immediate symptoms(症状), but a severe case can lead to death without immediately treatment.3. Do you know how to prove a new idea in scientific research?Anybody might come out with a new idea. But how do we prove it in scientific research? There are seven stages in examining a new idea in scientific research. And they can be put in the following order. What order would you put the seven in? Just guess.Find a problem→ Make up a question→ Think of a method→ Collect results→Analyse the results→ Draw a conclusion→ Repeat if necessaryUnit 1 Great scientistsPeriod 1 Warming up and reading课型Type of Lesson: Reading学习目标Learning aims:1.

Reading 阅读Step I Pre-reading 预读1.Do you know John Snow?John Snow is a well-known doctor in the 19th century in London and he defeated “King Cholera”.2.Do you know what kind of disease is cholera?It is a kind of terrible disease caused by drinking dirty water and it caused a lot of deaths in the old times and it was very difficult to defeat.Let’s get to know how Dr. John Snow defeated “King Cholera” in 1854 in London in this reading passage:Step II Skimming 扫读Read the passage and answer the questions.1.Who defeats “King Cholera“? (John Snow)2.What happened in 1854? (Cholera outbreak hit London.)3.How many people died in 10 days? (500)4.Why is there no death at No. 20 and 21 Broad Street as well as at No. 8 and9 Cambridge Street?(These families had not drunk the water from the Broad Street pump.)(Optional)Skim the passage and find the information to complete the form below.Step III Scanning 找读Read the passage and number these events in the order that they happened.2 John Snow began to test two theories.1 An outbreak of cholera hit London in 1854.4 John Snow marked the deaths on a map.7 He announced that the water carried the disease.3 John Snow investigated two streets where the outbreak was verysevere.8 King Cholera was defeated.5 He found that most of the deaths were near a water pump.6 He had the handle removed from the water pump.Step IV Main idea and correct stage 精读Read the passage and put the correct stages into the reading about researchinto a disease.John Snow Defeats “King Cholera”Step V Group discussion 分组讨论Answer the questions (Finish exercise 2 on Page 3)1. John Snow believed Idea 2 was right. How did he finally prove it?(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.)2. Do you think John Snow would have solved this problem without the map?(No. The map helped John Snow organize 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.)3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?(Two diseases, which are similar today, are SARS and AIDS because they are both serious, have an unknown cause and need public health care to solve them.)Step VI 概括总结Using the stages for scientific research and write a summary.Unit 1 Great scientistsPeriod 2&3 Language focus 课时：课型Type of Lesson: Words & Expressions学习目标Learning aims: To help students learn to use some important words and expressions教学重点Important Points: To help students learn to remember some important words and expressions教学难点Difficult Points: To help students learn to use some important words and expressions教学反思Teaching Re-thinking:家庭作业Homework:教学过程Teaching Procedures:Step I Warming up 热身1.characteristic①n. a quality or feature of sth. or someone that is typical of them and easyto recongnize.特征；特性What characteristics distinguish the Americans from the Canadians.②a. very typical o f a particular thing or of someone’s characer 典型性的，Such bluntness is characteristic of him.Windy days are characteristic of March.[辨析]characteristic与charactercharacteristic是可数名词，意为“与众不同的特征“character表示（个人、集体、民族特有的）“性格、品质”，还意为“人物；文字”What you know ab out him isn’t his real character.2. put forward: to state an idea or opinion, or to suggest a plan or person, for other people toconsider提出He put forward a new theory.The foreigners have put forward a proposal for a joint venture.An interesting suggestion for measuring the atmosphere around Mars has been put forward.☆ put on穿上;戴上;增加put out熄灭(灯);扑灭(火) put up with…忍受put down写下来;放下； put off 耽误;
