Unit 1 Great scientistsBrief Statements Based on This Unit This 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, language focusing, reading and writing, grammar, and assessment.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’ Revolutionary Theory, and their skills of reading, speaking and writing will be improved.In listening and speaking, more chances will be given to the students to learnabout 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.So, this unit will be divided into seven periods as follows:Period 1 Welcome to the UnitPeriod 2 ReadingPeriod 3 Listening and SpeakingPeriod 4 Reading and WritingPeriod 5 GrammarPeriod 6 Language FocusingPeriod 7 AssessmentKnowledge aims:Key words in this unit: 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.Key phrases in this unit: put forward, know about, look into, in addition, prevent sth.from doing, lead to, make sense, punish sb.for, suggest doing sth.steam engine, draw a conclusion, link...to..., be strict with, lead to, point of view.Key sentence patterns:1 But he became inspired when he thought about helping ordinary people exposed to cholera.2 He got interested in two theories explaining how cholera killed people.3 Only if you put the sun there did the movements of the other planets in the sky make sense.Grammar in this unit:Past participle used as attribute and predicativeAbility aims:1.To talk about great scientists and their great achievements.2.To guess what will be talked about in the listening materials.3.To improve their reading skills.4.To learn to use past participle as attribute and predicative.Emotion aims:To encourage the students to learn about some great scientists and their great achievements and 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 unit 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 bythemselves, 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 can encourage the students talk 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 great scientists and let other students guess who he or she is talking about.In this way, the students should learn to organize their own sentences and express their ideas clearly.After that, the students will feel comfortable to do the quiz in the text.The students should be encouraged to give more information about these ten scientists.Me anwhile, the students’ interest in scientists and science should be cultivated.So two topic discussion questions, as well as the practice exercises are designed.The post-class activities are designed to arouse the students’ interest in science and encour age 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, 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.Teaching DifficultiesWhat can we learn from the scientists?What should we do in our daily life to develop our interest and love for science?Teaching AidsCAI equipment with a Multi-media classroom and other normal teaching tools.Three Dimensional Teaching AimsKnowledge AimsLearn something about some famous scientists in the world.Know about the outstanding discoveries, inventions and theories from some well-known scientists.Try to understand and learn the important words and expressions.Ability AimsDevelop the students’ ability of spea king.Encourage the students to give more information about the great scientists.Emotional AimsEncourage the students to learn more about

You have done a good job.I will give you some more minutes to go over all the words and expressions and then fill in the blanks with proper forms of some of them from this unit.1.“All roads lead to Rome, ”he encouraged me after I failed the entrance examination.2.This sentence doesn’t make any sense.3.Our English teacher is not only strict with us but also friendly to us.4.He is good-looking, apart from his nose.5.It is announced that the spacecraft, Shenzhou Ⅵ, landed on the earth successfully.6.It is not Tom but you who are to blame.7.In 1995, the Chinese government put forward a pl an for“rejuvenating the nation by relying on science and education”.And it has helped Chinese scientists make many breakthroughs.8.Have you drawn any conclusion after you read this passage?T: Well done.So much for the learning of the new words and expressions.Step 4 BrainstormingT: Now let’s come to the title of this unit Great scientists.When we talk about great scientists, what will come into your mind(s)?We will go on our competition.S1: Madame Curie, who got two Nobel Prizes, one for physics and the other for chemistry, is really outstanding among all the women scientists.S2: It reminds me of the great inventor named Thomas Alva Edison and one of his famous sayings“Genius is one percent inspiration and ninety-nine percent perspiration.”S3: Yes, we lead a better life now with the help of science.Without Edison, maybe now we are still living in a dark world.They really make our life easier and more comfortable.S4: I also think of one of the quotes from Albert Einstein, “Imagination is more im portant than knowledge.”S5: All the scientists are devoted to the career that they choose, and they set good examples to us in our work.S6: Take all the scientists for example, if we want to be successful in the future, we should not only learn something from our textbooks, but also take part in social practice and get close to nature to learn more about it.S7: I like plants very much.I just think of the two key scientists in the field of botany, Carl Linnaeus and Joseph Banks.The former one laid the foundation for the classification of plants, while the latter one also made great contributions to the development and direction of botany.Ss: ...T: I’m glad to see that you have a great deal of previous knowledge of famous scientists in the world.Step 5 Previous knowledgeT: Now let’s match some of the great scientists with their famous discoveries, inventions or theories.Let me see who is the quickest in mind and action and can get all the answers correct.Famous scientists Discoveries/Inventions/TheoriesA.Isaac Newton 1.Evolution (进化论)B.Charles Darwin 2.Discovery of Radium（镭）C.Madame Curie 3.Newton’s LawD.Albert Einstein 4.Electric bulbE.Thomas Alva Edison 5.Theory of RelativityF.Nicolaus Copernicus 6.SeismographG.Stephen Hawking7.A Brief History of TimeH.Zhang Heng8.The earth moves around the sun.(Check the answers with all the students: A—3, B—1, C—2, D—5, E—4, F—8, G—7, H—6.)T: Since you have a better understanding of some of the great scientists, let’s play a game. Please work in groups and describe one of the great scientists, and then let other students guess who you are talking about.Group 1: In the eighteenth century, there lived a great scientist who conducted a number of experiments in which he showed what electricity is.Once he did a famous kite experiment on a stormy day, and proved that lightening and electricity are the same thing.S: Benjamin Franklin.Group 2: It is said that this English gentleman was sitting in his garden oneday when suddenly he was hit by a falling apple.The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples fall from a tree.His name makes you think that he was not too interested in old things.He discovered the force of gravity, and he drew up a system of how objects move.His laws for motion are still used in physics today, at least in schools and universities.S: Sir Issac Newton.Group 3:Food is what sets this great mind on fire.Rice, to be exact.This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat.He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be kno wn as“the farmer”.S: Yuan Longping.Group 4: He was born on 8 January 1942 in Oxford, England.He has worked on the basic laws which govern the universe.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.He has three popular books published: his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell.S: Stephen Hawking.Ss: ...T: Well done.Step 6 QuizT: You have already known some information about some of the great scientists.Now let’s do a quiz, trying to find out who these scientists are.Quiz Questions1.Which scientist discovered that objects in water are lifted up by a force thathelps them float?2.Who wrote a book explaining how animals and plants developed as the environment changed?3.Who invented the first steam engine?4.Who used peas to show how physical characteristics are passed form parents to their children?5.Who discovered radium?6.Who invented the way of giving electricity to everybody in large cities?7.Who was the painter that studied dead bodies to improve his painting of people?8.Who invented a lamp to keep miners safe underground?9.Who invented the earliest instrument to tell people where earthquakes happened?10.Who put forward a theory about black holes?Check the answers with the students.1.Archimedes2.Charles Darwin3.James Watt4.Gregor Mendel5.Madame Curie6.Faraday7.Leonardo davinci8.Humphrey Davy9.Zhang Heng10.Stephen HawkingT: Please work in groups and have a discussion to find as much information as possible about these ten great scientists.(The teacher had better join in the discussion and give them some guidance whenever necessary.After the discussion, ask some students to give a short report about what the group have discussed.)(Refer to the information about these scientists below, and various answers are possible.)Step 7 PracticeT: Today we have learned a lot about great scientists in the world.We can learnfrom them to live our dreams.And we teachers are too willing to help you.In your opinion, what should our school /teachers/students do to tap the students’ potential?S: Our school should give the students more chances to take part in social practice.S: Our teachers should help the students use their imaginations.S: We students should solve the problems on our own.(Ask more students to give their opinions.The teacher should encourage them, join them, praise them, and make comments on their ideas.)Step 8 Discussion (Group Competition)T: Your ideas are so wonderful and amazing.I admire them very much.Now let’s come to our topic.Topic 1: What can you learn from these scientists?Topic 2: What qualities should we have to be a successful man?(Give the students several minutes to have a discussion.Then let them have a group competition.)Step 9 Summing upT: In this period, we have talked a lot about great scientists.You have a lot of previous knowledge and you are full of imagination and creativity.Those scientists set good examples to us.And I think all of us are happy about learning more of them.After class, it’s better to read some books about them and you can surf the Internet to get more information.And I’d like you to make a“Scientists Album”in the following week.The Design of the Writing on the BlackboardUnit 1 Great scientistsPeriod 1 Welcome to the UnitBrainstormingResearch and ActivitiesDIY1.Cover a glass of water with a piece of thick paper.Put one hand on the paper and turn the glass upside down.Slowly take your hand away.What happens?Why?2.Fill one glass with fresh water and another glass with salt water. Put an ice cube in each glass.What happens?Why?3.Find out as many famous sayings from those scientists as possible.Reference for Teaching1.Charles Darwin was born in Shrewsbury(shropshire) to a moderately wealthy family with a strong intellectual heritage.His grandfather, Erasmus Darwin, was a physician, poet and biologist who laid som e of the groundwork for the grandson’s revolutionary ideas.Charles attended Christ’s College at Cambridge with initial thoughts of entering the clergy, but soon took up studies in biology, zoology and geology.From 1831 to 1836, he served as a naturalist aboard the HMS Beagle on its scientific mission to South America and the Pacific.Back in England, he published a series of scientific treatises which established his reputation as one of the prominent thinkers of his day.From 1842 onwards, he lived on a country estate in Kent and pursued his studies among its gardens and livestock.By 1844, he had written the initial draft of his groundbreaking treatise on evolution and natural selection.However, he left this work unpublished for several years, preferring to refine and elaborate its core ideas.In 1858, he read a forthcoming paper by a fellow scientist Alfred Russell Wallace whose thesis closely paralleled Darwin’s own unpublished ideas, an event which pushed Darwin to go public with his own research.Both Wall ace’s and Darwin’s papers were presented to the Linnean Society in a famous July, 1858 meeting. Darwin published The Origin of Species by Means of Natural Selection in 1859, sparking decades of contentious debate which ultimately led to the universal scien tific recognition of Darwin’s thesis.Inlater 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 Majesty’s Ship)treatises: 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, a lthough 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 of science.His 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 Baby Universes and Other Essays.Professor 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 and a Member of the US National Academy of Sciences.Stephen 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 attracted large audiences.In 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 and magnesium.Davy was now considered to be Britain’s leading scientist and in 1812 was knighted by George Ⅲ.With his assistant, Michael Faraday, Davy travelled abroad investigating his theory of volcanic action.In 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 up with this invention.One of Davy’s most important co ntributions 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 inventiveness that were centuries ahead of his time.5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In1891 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-pressure steam engine (patented 1769).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 characteristics through the combination of genes from parent cells.8.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 as a convenient source of heat.Michael 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。

Zhang Heng， ancient China， an inventor.10. Stepper Hawking， British， a physicist.Step Ⅲ Pre-readingGet 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.T: Now， class， please look at the slide. Discuss these questions with your partners. Then I’ll ask some students to r eport their work. Show the following on the screen.What do you know about infectious diseasesWhat do you know about choleraDo you know how to prove a new idea in scientific researchWhat order would you put the seven in Just guess.Sample answer 1:S1: Let me try. Infectious diseases can be spread easily. They have an unknown cause and may do great harm to people.S2: People could be exposed to infectious diseases， so may animals，such as bird flu.S3: AIDS， SARS are infectious diseases.S4: Infectious diseases are difficult to cure.Sample answer 2:S1: Cholera is caused by a bacterium called Varian cholera.S2: It infects people’s intesti nes， causing diarrhea， vomiting and leg cramps.S3: The most common cause of cholera is people eat food or drink water that has been contaminated by the bacteria.S4: Cholera can be mild or even without symptoms， but a severe case can lead to death without immediate treatment.Sample answer 3:S1: I know sth. about it. First we should find the problem. Then，think of a solution.S2: We should collect as much information as possible.S3: Analyzing results is the most important stage.S4: Before we make a conclusion， it is necessary for us to repeat some stages or processes.Sample answer 4:S1: I think ＂Find a problem＂ should be the first stage.S2: ＂Make up a question＂ should follow the first stage.S3: ＂Think of a method＂，＂Collect results＂and ＂Analyze results＂ are after that.S4: Of course， before ＂Make a conclusion＂， we should ＂Repeat if necessary＂.T: Well done！ When we want to solve some problems， first we should find out the problem， do some research on it， prove your findings， and then make a conclusion. This is a scientific and objective way of researching. Now let’s see how doctor John Snow did his research.Step Ⅳ ReadingLet the students skim the whole passage and try to work out the meanings of the new words and structures using context.T: The effect of cholera in the nineteenth century London was devastating. Many people died without knowing the reason. It was doctor John Snow who saved the people. Please look at the screen. Let’s read the whole passage and find answers to the questions.Show the questions on the screen.1. What conditions allowed cholera develop2. Why do you think people believed that cholera multiplied in the air without reason3. What evidence did John Snow gather to convince people that idea2 was rightSample answers:S1: The dirty water made the cholera develop quickly.S2: Because people could not understand its cause and could not get it cured. So people imagined that some poisonous gas in the air caused the deaths.S3: He found that many of the deaths were near the water pump while some areas far away from the water pump had no deaths. So when people were asked not to use the water pump， the disease began to slow down. In this way， John Snow had shown that cholera was spread by germs and not in a cloud of gas.Step Ⅴ Text analyzingAsk the students to analyze the text in groups.T: Please look at the chart on the screen. The chart shows that each paragraph of the text explains John Snow’s stages in his research. Please read the text and find out the general idea of each paragraph and match the stage with each paragraph. Discuss it in groups， and then report your answers.ParagraphsStagesGeneral ideasSample answers:S1: My group’s opinion is this: stage one ＂Find a problem＂ is expressed in paragraph one. The general idea is like this: John Snow wanted to find the causes of cholera.S2: Our answer is like this: paragraph two expresses the second stage ＂Make up a question＂. The general idea is like this: John Snow wanted to prove which theory was correct.S3: ＂Think of a method＂ is the third stage. And it is contained inparagraph three. The general idea is like this: John Snow collected data on those who were ill or died and where they got their water.S4: The fourth stage ＂Collect results＂ lies in paragraph four. Its general idea is like this: John Snow plotted information on a map to find out where people died or did not die.S5: Our group believe paragraph five contains the fifth stage of John Snow’s research. The general idea is like this: John Snow analysed the water to see if that was the cause of the illness. So this stage is to ＂Analyse the results＂.S6: The sixth stage is ＂Repeat if necessary＂. It is contained in the sixth paragraph. The general idea is like this: John Snow tried to find other evidences to confirm his conclusion.S7: The last paragraph is about the seventh stage ＂Make a conclusion＂. Its general idea is like this: The polluted dirty source of drinking water was to blame for the cause of the London cholera. Ask some students to put their answers in the chart.ParagraphStagesGeneral ideas1Find a problemThe causes of cholera2Make up a questionThe correct or possible theory3Think of a methodCollect data on where people were ill and died and where they got their water4Collect resultsPlot information on a map to find out where people died or did not die5Analyse the resultsAnalyse the water to see if that is the cause of the illness6Repeat if necessaryFind other evidences to confirm his conclusion7Make a conclusionThe polluted dirty source of drinking water was to blame for the cause of the London choleraT: 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.ReportDescriptionCreative writingFormal language with few adjectivesVivid use of words with similes and metaphorsVivid use of language and more informal styleNo speech exceptquotationsNo speech except to help the descriptionSpeech to show feelings， reactions etc.Not emotionalEmotional to describe atmosphereEmotional to describe feelingsOnly one main characterNo charactersMay have several charactersFactualNot factual but imaginativeImaginative but can be based on factStructural according to experimental methodNot structuredBeginning， middle， endPast tense and passive voicePast tensePast tenseMaking WayOnce 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 ReportHere’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 is4. New York will be sunny and cloudy later in the day. The temperature is 13 to 19.HeartbeatingPut 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 grown-up’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 passageS2: I can. Clearly it tells us how John Snow defeated the disease cholera by doing scientific research.StepⅥ Homework1. Get more information about some infectious diseases and modern scientists.2.

Brief 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, language focusing, reading and writing, grammar, and assessment.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 passa ge, 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 t he language, the students will learn about Copernicus’ Revolutionary Theory, and their skills of reading, speaking and writing will be improved.In 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.So, this unit will be divided into seven periods as follows:Period 1 Welcome to the UnitPeriod 2 ReadingPeriod 3 Listening and SpeakingPeriod 4 Reading and WritingPeriod 5 GrammarPeriod 6 Language FocusingPeriod 7 AssessmentKnowledge aims:Key words in this unit: engine, characteristic, radium, theory, scientific, examine, conclude, analyze, repeat, defeat, attend, expose, cure, control, absorb, severe,

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 can encourage the students talk 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 great scientists and let other students guess who he or she is talking about.In this way, the students should learn to organize their own sentences and express their ideas clearly.After that, the students will feel comfortable to do the quiz in the text.The students should be encouraged to give more information about these ten scientists.Meanwhile, the students’ i nterest in scientists and science should be cultivated.So two topic discussion questions, as well as the practice exercises are designed.The post-class activities are designed to arouse the students’ interest in science and encourage them to“DIY—do it yo urself” in their daily life if they have some doubt in someareas.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, 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.Teaching DifficultiesWhat can we learn from the scientists?What should we do in our daily life to develop our interest and love for science?Teaching AidsCAI equipment with a Multi-media classroom and other normal teaching tools.Three Dimensional Teaching AimsKnowledge AimsLearn something about some famous scientists in the world.Know about the outstanding discoveries, inventions and theories from some well-known scientists.Try to understand and learn the important words and expressions.Ability AimsDevelop the students’ ability of speaking.Encourage the students to give more information about the great scientists.Emotional AimsEncourage the students to learn more about the great scientists and learn from them.Help the students to form the good habit in learning and encourage the students to take part in social practice.Help the students to realize that it is scientific spirit that makes those scientists successful.Encourage the students to develop their love for science.Teaching ProcedureStep 1 GreetingTeacher: Hello, everyone.Teacher: Hello, Mr.../Ms...Step 2 Lead inT: I’m very glad to see you all here.After a long holiday, all of you look energetic and happy.I hope that we will work hard together happily all through the year.I do believe

beings.Ss: ...T: I’m so glad to share your dreams.Your ambition and careful thoughts really leave a good and a mazing impression on me.I like them.In this unit, you will learn something about“Great scientists”.Maybe you will know what you need in your efforts to realize your dreams after we talk about some world-famous scientists.Before we come to“Warming up”, I’d like you to come to the new words in this unit, which will help you to learn this unit.Step 3 Word puzzlesT: Open your books and turn to Page 92.Let’s read the words and expressions together.(Let the students read the words and expressions together.Help them pronounce the new words and expressions ter give them some time to practise reading and remember some easy and important ones.Give more help to those who are poor in pronunciation.) T: Here are some definitions of some of the words from this unit.Please work in pairs and match the words with their definitions.(group competition)Words Definitions or explanationsA.examine 1.general principles of an art or scienceB.repeat 2.say or do againC.theory 3.at once; without delayD.immediately 4.look at...carefully in order to learn about or from...plete 5.of great value, worth or useF.valuable 6.having all its parts; whole; finishedG.announce 7.make knownH.control e or bring to an endI.positive 9.power to order or directJ.conclude 10.quite certain or sureT: Now, let’s check the answers.A—4, B—2, C—1, D—3, E—6, F—5, G—7, H—9, I—10, J—8. You have done a good job.I will give you some more minutes to go over all the words and expressionsand then fill in the blanks with proper forms of some of them from this unit.1.“All roads lead to Rome, ”he encouraged me after I failed the entrance examination.2.This sentence doesn’t make any sense.3.Our English teacher is not only strict with us but also friendly to us.4.He is good-looking, apart from his nose.5.It is announced that the spacecraft, Shenzhou Ⅵ, landed on the earth successfully.6.It is not Tom but you who are to blame.7.In 1995, the Chinese government put forward a plan for“rejuvenating the nation by relying on science and education”.And it has helped Chinese scientists make many breakthroughs.8.Have you drawn any conclusion after you read this passage?T: Well done.So much for the learning of the new words and expressions.Step 4 BrainstormingT: Now let’s come to the title of this unit Great scientists.When we talk about great scientists, what will come into your mind(s)?We will go on our competition.S1: Madame Curie, who got two Nobel Prizes, one for physics and the other for chemistry, is really outstanding among all the women scientists.S2: It reminds me of the great inventor named Thomas Alva Edison and one of his famous sayings“Genius is one percent inspiration and ninety-nine percent perspiration.”S3: Yes, we lead a better life now with the help of science.Without Edison, maybe now we are still living in a dark world.They really make our life easier and more comfortable.S4: I also think of one of the quotes from Albert Einstein, “Imagination is more important than knowledge.”S5: All the scientists are devoted to the career that they choose, and they set good examples to us in our work.S6: Take all the scientists for example, if we want to be successful in the future, we should not only learn something from our textbooks, but also take part in social practice and get close to nature to learn more about it.S7: I like plants very much.I just think of the two key scientists in the field of botany, Carl Linnaeus and Joseph Banks.The former one laid the foundation for the classification of plants, while the latter one also made great contributions to the development and direction of botany.Ss: ...T: I’m glad to see that you have a great deal of previous knowledge of famous scientists in the world.Step 5 Previous knowledgeT: Now let’s match some of the great scientists with their famous discoveries, inventions or theories.Let me see who is the quickest in mind and action and can get all the answers correct.Famous scientists Discoveries/Inventions/TheoriesA.Isaac Newton 1.Evolution (进化论)B.Charles Darwin 2.Discovery of Radium（镭）C.Madame Curie 3.Newton’s LawD.Albert Einstein 4.Electric bulbE.Thomas Alva Edison 5.Theory of RelativityF.Nicolaus Copernicus 6.SeismographG.Stephen Hawking7.A Brief History of TimeH.Zhang Heng8.The earth moves around the sun.(Check the answers with all the students: A—3, B—1, C—2, D—5, E—4, F—8, G—7, H—6.)T: Since you have a better understanding of some of the great scientists, let’s play a game. Please work in groups and describe one of the great scientists, and then let other students guess who you are talking about.Group 1: In the eighteenth century, there lived a great scientist who conducted a number of experiments in which he showed what electricity is.Once he did a famous kite experiment on a stormy day, and proved that lightening and electricity are the same thing.S: Benjamin Franklin.Group 2: It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling apple.The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples fall from a tree.His name makes you think that he was not too interested in old things.He discovered the force of gravity, and he drew up a system of how objects move.His laws for motion are still used in physics today, at least in schools and universities.S: Sir Issac Newton.Group 3: Food is what sets this great mind on fire.Rice, to be exact.This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat.He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be known as“the farmer”.S: Yuan Longping.Group 4: He was born on 8 January 1942 in Oxford, England.He has worked on the basic laws which govern the universe.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.He has three popular books published: his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell.S: Stephen Hawking.Ss: ...T: Well done.Step 6 QuizT: You have already known some information about some of the great scientists.Now let’s do a quiz, trying to find out who these scientists are.Quiz Questions1.Which scientist discovered that objects in water are lifted up by a force that helps them float?2.Who wrote a book explaining how animals and plants developed as the environment changed?3.Who invented the first steam engine?4.Who used peas to show how physical characteristics are passed form parents to their children?5.Who discovered radium?6.Who invented the way of giving electricity to everybody in large cities?7.Who was the painter that studied dead bodies to improve his painting of people?8.Who invented a lamp to keep miners safe underground?9.Who invented the earliest instrument to tell people where earthquakes happened?10.Who put forward a theory about black holes?Check the answers with the students.1.Archimedes2.Charles Darwin3.James Watt4.Gregor Mendel5.Madame Curie6.Faraday7.Leonardo davinci8.Humphrey Davy9.Zhang Heng10.Stephen HawkingT: Please work in groups and have a discussion to find as much information as possible about these ten great scientists.(The teacher had better join in the discussion and give them some guidance whenever necessary.After the discussion, ask some students to give a short report about what the group have discussed.)(Refer to the information about these scientists below, and various answers are possible.) Step 7 PracticeT: Today we have learned a lot about great scientists in the world.We can learn from them to live our dreams.And we teachers are too willing to help you.In your opinion, what should our school /teachers/students do to tap the students’ potential?S: Our school should give the students more chances to take part in social practice.S: Our teachers should help the students use their imaginations.S: We students should solve the problems on our own.(Ask more students to give their opinions.The teacher should encourage them, join them, praise them, and make comments on their ideas.)Step 8 Discussion (Group Competition)T: Your ideas are so wonderful and amazing.I admire them very much.Now let’s come to our topic.Topic 1: What can you learn from these scientists?Topic 2: What qualities should we have to be a successful man?(Give the students several minutes to have a discussion.Then let them have a group competition.)Step 9 Summing upT: In this period, we have talked a lot about great scientists.You have a lot of previous knowledge and you are full of imagination and creativity.Those scientists set good examples to us.And I think all of us are happy about learning more of them.After class, it’s better to read some books about them and you can surf the Internet to get more information.And I’d like you to make a“Scientists Album”in the following week.The Design of the Writing on the BlackboardUnit 1 Great scientistsPeriod 1 Welcome to the UnitBrainstormingResearch and ActivitiesDIY1.Cover a glass of water with a piece of thick paper.Put one hand on the paper and turn the glass upside down.Slowly take your hand away.What happens?Why?2.Fill one glass with fresh water and another glass with salt water. Put an ice cube in eachglass.What happens?Why?3.Find out as many famous sayings from those scientists as possible.Reference for Teaching1.Charles Darwin was born in Shrewsbury(shropshire) to a moderately wealthy family with a strong intellectual heritage.His grandfather, Erasmus Darwin, was a physician, poet and biologist who laid some of the groundwo rk for the grandson’s revolutionary ideas.Charles attended Christ’s College at Cambridge with initial thoughts of entering the clergy, but soon took up studies in biology, zoology and geology.From 1831 to 1836, he served as a naturalist aboard the HMS Beagle on its scientific mission to South America and the Pacific.Back in England, he published a series of scientific treatises which established his reputation as one of the prominent thinkers of his day.From 1842 onwards, he lived on a country estate in Kent and pursued his studies among its gardens and livestock.By 1844, he had written the initial draft of his groundbreaking treatise on evolution and natural selection.However, he left this work unpublished for several years, preferring to refine and elaborate its core ideas.In 1858, he read a forthcoming paper by a fellow scientist Alfred Russell Wallace whose thesis closely paralleled Darwin’s own unpublished ideas, an event which pushed Darwin to go public with his own research.Both Wallace’s and Darwin’s papers were presented to the Linnean Society in a famous July, 1858 meeting. 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 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 (Her/His Majesty’s Ship)treatises: 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 abeginning 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 of science.His 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 Baby Universes and Other Essays.Professor 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 and a Member of the US National Academy of Sciences.Stephen 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.Humph ry 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 attracted large audiences.In 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 and magnesium.Davy was now considered to be Britain’s leading scientist and in 1812 was knighted by George Ⅲ.With his assistant, Michael Faraday, Davy travelled abroad investigating his theory of volcanic action.In 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 up with this invention.One of Davy’s most important contributions to hi story 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 inventiveness that were centuries ahead of his time.5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In 1891 shewent 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-pressure steam engine (patented 1769).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 characteristics through the combination of genes from parent cells.8.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 as a convenient source of heat.Michael 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.。

Cholera may be rare nowadays except in some poor areas, but back in the 1830s-1840s, it was probably No.1 killer in the world. There were four outbreaks of cholera in the 1830s and 1840s, which killed many thousands of people in the industrial cities of England. In 1854 on August 31st “the most terrible outbreak of cholera which ever occurred in the kingdom” began. It was so violent and sudden that 127 people around Broad Street died in the first three days. And then a famous physician John Snow discovered the source of the disease and since then Cholera was finally brought under control.2. How did he solve the problem of cholera? Actually, he followed a scientific procedure to carry out his scientific research. The whole procedure is made up of 7 steps.

He was originally an anesthetist(麻醉师).He was so famous that he became the doctor for Queen Victoria at the births of her many children.Four outbreaks of cholera in the 1830s and 1840s killed many people in England. In 1854, “the most terrible outbreak of cholera which ever occurred in the kingdom” began. It was so violent and sudden that 127people died in the first three days. Step 2 Skimming and ScanningMore questions are given to get the general ideas of this passage and some obvious facts.Who defeats “King Cholera“? John SnowWhat happened in 1854? Cholera outbreak hit London.How many people died in 10 days? 500Why is there no death at No. 20 and 21 Broad Street as well as at No. 8 and 9 Cambridge Street?These families had not drunk the water from the Broad Street pump.Step 3 Reading for details1. Why couldn’t the cholera be under control at first?Neither its cause, not its cure was understood.2. Which theory did John Snow believe in?People absorbed cholera into their bodies with their meals.3. John Snow finally proved the theory he believed by ________.gathering information with the help of a maplooking into the source of the water for Broad Street and Cambridge Street Separating those who suffered cholera from those who didn’tBoth A and B (right choice)4.
