Period 5 GrammarThe General Idea of This PeriodThis is the fifth period, which will center on the grammar: using the past participle as the attribute and the predicative.At the beginning of this period, the teacher should give the students some time to go over what they learned in the last period.Later the teacher had better present some sentences containing the past participle used as the attribute and the predicative on purpose by asking the students to do some exercises.Get the students to find all the sentences containing the past participle in the two passages.After finding them, the teacher can ask the students to analyze them and understand the function of the past participle in those sentences.After that the teacher should give the students clear explanations about the usage of the grammar.After mastering the rules of the past participle, the students should be given more exercises to consolidate what they learn.The teacher should arrange some activities carefully and creatively. First let them do some simple exercises.For example, combine the two sentences using the past participle as the attribute and the predicative.Then ask them to make some sentences using the past participle.Besides that, the teacher should help the students to review the other usages of the past participle.In the end, let them write a passage using the past participle properly.Apart from the usage of the past participle, the teacher had better make the students understand the differences between the past participle and the present participle.In order to have the students master it, the teacher should choose some exercises to supply the students with some problems to deal with.By doing and practicing more, the students may master the grammar.T eaching Important PointTo learn about the past participle used as the attribute and the predicative.T eaching DifficultyTo know the differences between the past participle and the present participle.T eaching AidsMulti-media classroom and other normal teaching tools.Three Dimensional T eaching AimsKnowledge AimTo learn about the past participle used as the attribute and the predicative.Ability AimTo use the past participle used as the attribute and the predictive freely and properly in speaking and writing.Emotional AimsEncourage the students learn more about the grammar.Help the students to form the good habit in learning.Encourage the students to do more exercises to consolidate their knowledge.T eaching ProcedureStep 1 GreetingT: Hello, my friends.Ss: Hello, Miss...Step 2 RevisionT: Do you still remember what you learned in this unit?Would you please say somethingabout the great scientists we learned in this unit.First please something about John Snow.S: John snow, a well-known doctor in London, defeated cholera.S: He got interested in two theories explaining how cholera killed people.S: John Snow gathered the information and marked it on a map where all the dead people had lived.S: He discovered that many of the deaths were near the water.It seemed the water was to blame.Ss: ...T: Y ou really did a very good job.Now, let’s say something about Nicolaus Copernicus.S1: Nicolaus Copernicus believed that the earth is not the centre of the solar system.But at that time people all believed God had made the world and for that reason the earth was special and must be the centre of the solar system.S2: In 1514 he showed his theory privately to his friends and explained his theory.S3: He was very cautious because he did not want to be attacked by the Christian church.S4: He published his theory as he lay dying in 1543.S5: His theory was rejected by the Christian Church.Step 3 PresentationT: Today we will learn the grammar—past participle used as the attribute and the predicative. First look at your text on Page 4, part I.Look at the following sentences where the past participles are used.T: In this sentence the past participle is used as an attribute phrase.Terrified people means people who were terrified.Now please find two more examples from the reading passages with past participles used as the attribute.Y ou are allowed to find as many sentences as possible in two minutes.(Two minutes later, ask the students to report what they have found.)S1: From the stomach the disease attacked the body quickly and soon the affected person was dead.S2: Immediately John Snow told the astonished people in Broad Street to remove the handle from the water pump so it could not be used.S3: John Snow suggested that the source of all water supplies be examined and new methods of dealing with polluted water be found.S4: He placed a fixed sun at the centre of the solar system.T: Good.Y ou just found all the sentences containing the past participles used as the attributes .Besides using as the attribute, the past participles can also be used as the predicative.Can you find the sentences with past participles used as the predicative?Finish it in two minutes.(Two minutes later, let the students read these sentences with past participles as the predicative.)S1: Neither its cause, nor its cure was understood.S2: He knew it would never be controlled until its cause was found.S3: He got interested in two theories explaining how cholera killed people.S4: They were given free beer and so had not drunk the water from the Broad Street pump.S5: He found that it came from the river, which had been polluted by the dirty water from London.S6: Immediately John Snow told the astonished people in Broad Street to remove the handle from the water pump so it could not be used....Step 4 PractisingT: From the sentences mentioned just now, what do you know about the usage of past participles as the attribute and the predicative?S: We use past participles as attributes when we want to join two clauses together.Suggested answers:1.people who are terrified2.seats which are reserved3.water which is polluted4.a room which is crowded5.a winner who is pleased6.astonished children7.a broken vase8.a closed door9.the tired audience10.a trapped animal过去分词作定语, 在语态上, 表被动; 在时间上, 表示动作已经发生或完成, 与它所修饰的名词有逻辑上的动宾关系。

Unit 1Great 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 ofAssessment will help the students to look back what they have learned and focus on the difficult and important points.So, this unit

to learn from the scientists and form their positive attitude towards science.Period 1Welcome 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, andWords and expressions in this unit will help the students to talk about the topic“great sci entists”.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.and let other students guess who he or she is talking about.In this way, the students should learn toAfter that, the students will feel comfortable to do the quiz in the text.The students should beMeanwhile, the students’ interest in scientists and science should be

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treatises: 论文2.Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford, Engl and.His parents’ house was in north London, but during the Second World WarOxford 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 completelyHis 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 ofProfessor 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 andStephen 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 unitedwith 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 knighted 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 mechanical5.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 the8.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.

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

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。

Warming up⑴Warming up by definingGood morning, class. I am glad to see you on this special day, the day when you become a senior two student. I am happy to be your teacher of English.Today we are going to read about a certain scientist. But first let’s define the word “scientist”. What is a scientist?⑵Warming up by asking and answering questions about scienceTo begin with, work in groups of four and find out as many scientists as possible and their contributions. They can be both Chinese and foreign scientists, living or dead.⑶Warming up by talking about t op honor for two Chinese scientistsHello, everyone. Nice meeting you here. You are now a senior two student. Some of you will be a scientist in the future. But have you ever heard that Yuan Longping, director-general of the China National Hybrid Rice Research and Development Centre in central China's Hunan Province and Bai Chunli, vice-president of the Chinese Academy of Sciences in Beijing were formally introduced to the academy on April 28, 2007 at a global meeting of US academy members and foreign associates.●Yuan Longping, director-general of the China National Hybrid Rice Research and Development Centre in Central China's Hunan Province and Bai Chunli, vice-president of the Chinese Academy of Sciences in Beijing were formally introduced to the academy last Saturday at a global meeting of US academy members and foreign associates.Yuan, 77, dubbed the "father of hybrid rice" for his extraordinary contributions toward developing high-yield rice, is a household name in China.With more than half of China's paddy fields growing Yuan's rice, his scientific breakthrough has fed millions of people in the world's most populous country.His "super rice" has also been introduced to more than 20 other countries.●Bai, 52, is considered to be a leading expert in China's molecular nanostructure and nanotechnology studies."I think the fast development of Chinese science has drawn increased attention from the US academy," Bai said in an interview with China Daily last year shortly after he was elected.2. Pre-reading by sharing opinions on proving a new ideaAnybody might come out with a new idea. But how do we prove it in scientific research? How many stages are there in examining a new idea in scientific research? What are they?Now look at the blackboard to learn about the seven stages put in an order.Could you give an example to illustrate the seven stages?3.

Reading skills are very important for senior students.For the first reading, we intend to cultivate Ss’ skimming ability and scanning ability.First ask the students to scan it and tick out what...are mentioned in the passage.Then let the students read fast to find out the main idea of each paragraph.In order to stimulate Ss to take part in the class activity more actively, the teacher can organize a group competition to see which group can finish the task fastest and best.For the second reading, the students are expected to know some details about the ter on, the teacher will present some questions for the students to answer and at the same time they are asked to finish filling in the chart.The third time is to read for further information.This part is designed to get Ss into the habit of reading a passage as a whole, that is, to get the general idea.Another purpose of this part is to ask Ss to pay attention to the details. To develop Ss’ further understanding ability, the teacher can design some questions, whose answers are beyond lines.So the teacher will help them to read between the lines, thus Ss can gradually get the ability to understand the implied meanings.In this step, the teacher asks Ss to read it again in order to make them think about the organization of the whole passage, and this method can help them not only in their understanding this passage but also in writing a short passage. To consolidate the content of the passage, Ss are required to retell it according to the main idea.In order to arouse the Ss’ interest; the teacher can hold a competition between groups.After the students understand the whole passage, they are asked to have a topic discussion. Teaching Important PointsHave a good understanding of the text by doing the exercises. Get the students to learn different reading skills, especially gist reading and comprehending beyond lines.Teaching DifficultiesKnow the meanings between lines and beyond lines. Learn different reading skills for different reading purposes. Teaching AidsMulti-media classroom and other normal teaching tools.

Suggested answers:Scientific Report by John Snow The problemThousands of people died of cholera every time there was an outbreak.Neither its cause, nor its cure was understood. The causeIdea 1 Cholera multiplied in the air without reason. Idea 2 People absorbed this disease into their bodies with their meals. The method He began to gather the information.He marked on a map where all the dead people hadlived and the map gave a valuable clue about the cause of the disease.He looked into thesource of the water.The results Polluted water carried the disease.People who drank the polluted water died of Cholera.Idea 1 or 2?Why? Idea 2 is correct.He found two other deaths in another part of London that were linked tothe polluted water.With this extra evidence, he was able to announce that polluted watercarried the disease.The conclusion“King Cholera” was defeated.Fourth Reading: Further understandingT: From the passage, we know that John Snow believed that Idea 2 was right.How did he finally prove it?If you get your answer right, I’ll give you thirty marks. Ss: John Snow believed in the second theory but needed to prove he was correct.So when another outbreak hit London in 1854 and it spread quickly through the poor neighbourhoods, he began to gather the information.He determined to find out why.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.He looked into the source of the water for Broad Street and Cambridge Street.He had shown that cholera was spread by germs and not in a cloud of gas.In addition, he found two other deaths in another part of London that were linked to the Broad Street outbreak.They died of cholera after drinking the polluted water.With extra evidence, he was able to announce that polluted water carried the disease.Finally King Cholera was defeated. T: You really did a good job.Do you think John Snow would have solved this problem without the map?Why?If you get your answer right, I’ll give you thirty marks. S: I think he would have solved the problem.But he would spend more time in testing the two theories and it would be more difficult for him to look into the cause of cholera.(The teacher should give them about two minutes to discuss, and join in the discussion at the same time.After that, the students will be asked to show their opinions to the whole class.) Step 6 ConsolidationT: In this period, we have learned a lot about John Snow and King Cholera.What have you learned from it?I will give you one minute to prepare for it.If your sentence is quite good, I’ll give you thirty marks.(After one minute.) S1: John Snow was a well-known doctor in London. S2: He attended Queen Victoria to ease the birth of her babies. S3: He got interested in two theories explaining how cholera killed people. S4: John Snow had shown that cholera was spread by germs and not in a cloud of gas. S5: John Snow announced that polluted water carried the disease. S6: ... T: Your sentences are so wonderful and amazing.I admire them very much.Who would like to retell the whole passage to us?If you can, I’ll give you fifty marks. Ss: ... Step 7 Topic discussionT: Now let’s come to our topic.We know cholera was a 19th century disease.What disease do you think is similar to cholera today?Why?If you show quite a good opinion, I’ll give you thirty marks.But first I will give you two minutes to discuss it with your partner. (The teacher should give them about two minutes to discuss, and join in the discussion at the same time.After that, the students will be asked to show their opinions to the whole class.) S: Since a lot of people die of bird flu, I think bird flu today is similar to cholera.Now the cause of bird flu is not quite clear, but scientists devote their lives to finding out the cause and the cure.S: In my opinion, SARS is quite similar to cholera.SARS is spread by germs in the air while cholera is spread by germs in the polluted water.A lot of people have been dying of SARS.Ss: ... T: This time, the first/second group won the competition.Congratulations! T: I’d like you to write a short passage about John Snow according to the passage.

The World Health Organization says it is concerned that the disease could spread to the Darfur region of western Sudan, which is already struggling with his own humanitarian crisis due to violence.The government of Chad says more than 2000 cases of cholera have been reported in the country, and it expects that number to more than double by the end of the rainy season in September.Although, the majority of cases in Chad are being reported in the region surrounding the capital in the west. But the WHO says it is deeply worried that it could spread to neighboring Sudan and the refugee camps sprawled across its troubled western region of Darfur. An expert with the WHO, Claire ‐lise Chaignat, says the disease is endemic to mainly poorer areas that do not have access to safe water supplies. “Another factor is also the refugees living in refugee camps where they are living in close communities with not enough water and no proper sanitation, ”she said. “So, that is also a high risk for the community. So, for example, we are very much scared that, now, in the crisis in Darfur, or in the eastern Chad, there might be a cholera outbreak. In case the germ occurs because the water and sanitation situation is so bad that it’s really, a real risk that we might have a cholera outbreak there. ” Chad has been battling a potential locust scourge in the west, and has received an influx of refugees in the east from the fighting taking place in the Darfur region. The government is asking for nearly $200 000 in aid to try to curb the spread of cholera. Cholera outbreaks are being reported throughout much of central and western Africa thisyear, including Cameroon, Sierra Leone, Guinea and the Democratic Republic of Congo. The disease spreads quickly in areas where water supplies are contaminated and causes dehydration within days. It can lead to death if victims are untreated within a week. Carrie Giardino, VOA News, Abidjan. The strains of cholera bacteria prevalent in China make change and experts warn for possible outbreak. In China’s database of epidemic status, a painting depicted with the three epidemic waves documented in figures the status of cholera epidemic in the past 40 years throughout the country. Each time of fluctuations in the epidemic graph was related to the changes of cholera bacterial typing. The latest data of monitoring showed that the dominating bacterial type of cholera epidemics had another change emerging with a unique epidemic bacterial type. Specialists of the Chinese Center for Disease Control (CDC) warned that the possible aftermath of epidemic situation resulted from the changes of bacterial type of cholera must be dealt with intensive precaution. Academician Gao Shouyi of Chinese CDC pointed out that the Inaba 1d strain emerged predominantly since last year, had the character of wide distribution of the same strain, and its 16S ribosomal gene probe hybridization belonged to the same strain seen in the majority of the provinces. In a certain location of the Southern provinces, the eltor strain, in addition to the occurrence of Inaba 1d strain, also partially emerged with the 1c, 1b, 1f strains;however, its ribosomal typing was identical with the predominant epidemic Inaba 1d strain, all came from the same clone line. In certain places of the southern west area the Ogawa type that mutated into Inaba type emerged;and the Inaba strain occurred in 2001 was not the continuation of the Inaba strain of 2000;additionally in another location of the south western area an Ogawa 6b unique epidemic strain occurred. From 18‐19 April, a working conference of national prevention and treatment of gastrointestinal infectious diseases was held in Beijing jointly sponsored by the Chinese CDC and the consultative committee of diarrhea specialists of Ministry of Health. The related specialists and the leading members of the CDC were organized to carry out an outspread discussion upon the subject of prevention and treatment of infectious diseases of the gastrointestinal tract, headed by cholera. On April 17th, the CDC issued notification to the CDC system throughout the country to carry out the weekly report of cholera epidemics and the acts of reports of the scattered cases;measures for augmentation of monitoring and retrieve of epidemic sources were also arranged.。

Unit 1Great 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, 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 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 1Welcome to the UnitPeriod 2ReadingPeriod 3Listening and SpeakingPeriod 4Reading and WritingPeriod 5 GrammarPeriod 6Language

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 1Welcome 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 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 beencouraged to give more information about these ten scientists.Meanwhile, 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 encourage them to“DIY—do it yourself” in their daily life if they have some doubt in some areas.T eaching 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,

Y ou 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 plan for“rejuvenating the nation by relying on science and education”.And it has helped Chinese scientists make m any 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 g reat 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: Y es, 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 w ould rather be known as“the farmer”.S: Y uan 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: Y ou 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 Heng 10.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: Y our 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.Y ou 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 ma ke a“Scientists Album”in the following week.The Design of the Writing on the BlackboardUnit 1Great scientistsPeriod 1Welcome 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.

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 M ajesty’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 WarOxford 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 Mathematic s.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 Y ears 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 unitedwith 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 knight ed 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 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.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-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.。

【英语】高中英语新课标(人教版)必修五-优秀教案-(Unit-1-Great-scientists-P eriod-4)Period 4Reading and WritingThe General Idea of This Period In this period the teaching and learning will center on reading and writing.As usual, the teacher can begin the teaching with reviewing the former knowledge.The following part is the lead-in—talking about some scientists, because this unit talks about great scientists and this passage is about Nicolaus Copernicus and his theory.As to reading training, the teacher should still develop the students’ ability of scanning and skimming.So at the beginning, get the students to prepare some knowledge for reading. For that purpose, the teacher will firstly ask for information about Copernicus according to what the students already know.Then the teacher can have the students listen to the tape and find out whether the statements are true or false.It is designed to train the students’ listening and to check whether the students have previewed theCopernicus and his friend.The practicing helps the students improve their speaking and arouse their creativity.The competition is held to make the students take part in the class activities actively.At the same time, let the students consider the writing purpose.Besides reading, the students are also expected to learn and practise their writing skill.By studying the passage, the students should learn to do persuasive writing to change someone else’s decision.The teacher should give the students some advice on how to plan the writing and develop the writing—beginning, body and conclusion.Teaching Important PointsHelp the students know about Copernicus and his theory.Develop the students’ reading ability.Improve the students’ writing ability.Teaching DifficultyDevelop the students’ reading ability.Teaching AidsMulti-media classroom and other normal teaching tools.Three Dimensional Teaching Aims Knowledge AimsGet the students to know about Copernicus and his theory.Learn about persuasive writing.Ability AimsMaster the skill of gist reading.Develop the students’ reading ability, such as skimming and scanning.Improve the students’ writing ability.Emotional AimsArouse the students’ interest in science and devotion to science.Teaching ProcedureStep 1 GreetingT: Hello, everyone.Ss: Hello, Miss Wang.Step 2 ReviewingT: Last class we talked about Qian Xuesenand Carl Linnaeus.Can you say something about them?S: Qian Xuesen is a famous Chinese physicist.S: Qian Xuesen once studied in the USA and then returned to China.S: Qian Xuesen made great contributions to space research.S: Carl Linnaeus developed a system to classify plant species according to the male and female organs in the followers.S: Carl Linnaeus earned the title“Father of classification”.Ss: ...Step 3 Pre-readingT: You have done a good job.So we have learned about a lot about great scientists, such as John Snow and Qian Xuesen.Who else would you like to learn about?Why?S1: I’d like to know something about Madame Curie, because she was one of the great women scientists.S2: I’d like to know about Albert Einstein, because he plays an important part in the development of Physics.S3: Stephen Hawking because he has made great achievements although he is disabled.Ss: ...T: I find you are interested in science and scientists.But today we are going to read about Copernicus.Do you know something about him?S1: He was born in Poland.S2: He believed the earth moves around the sun.S3: It was said that he was burned to death because of his theory.Ss: ...T: Do you want to know more about him?Ss: Of course.T: So let’s come to the passage Copernicus’ revolutionary theory.Step 4 ListeningT: First I’d like you to listen to the tape and find out whether the statements are T or F.(Give the students one minute to read the statements and then play the tape.)() 1.When Copernicus found that the earth was not the center of the solar system, he was very excited.() 2.Some astronomers found it strange that some planets appeared brighter at sometimes.() 3.Copernicus worked out the theory by observation and calculation.() 4.Copernicus didn’t publish his ideas until he died in 1543.() 5.According to the Christian idea of gravity, things fell to the ground because the earth is the center of the universe.(A few minutes later.)T: Are you ready?W ho’d like to have a try.If the sentence is true, please read it.If it is false, correct it.S1: The first sentence is false.When Copernicus found that the earth was not the center of the solar system, he was frightened.S2: The second statement is true.S3: The third statement is also true.S4: The fourth statement is false.Copernicus didn’t publish his ideas until he lay dying in 1543.S5: The fifth statement is true.Suggested answers:1.F;2.T;3.T;4.F;5.TStep 5 Gist ReadingT: You have done a good job.In think you previewed the passage well.To understand the passage better, I divide the passage into four parts.Read the passage quickly and find out the main idea of each part.(After three minutes.)T: Have you got it?Generally speaking, if we want to introduce something, first, we usually give a brief introduction.What about the main ideas of other parts?(Ask the students to give their opinions and in the end the teacher gives them the answer.) Suggested answers:Para 1 Brief introductionPara 2 The cause of Copernicus’ theoryParas 3-4 The process of Copernicus’ theoryPara 5 The significance of Copernicus’ theoryStep 6 Detailed readingT: This passage mainly talks about Copernicus’ theory.So let’s compare his theory and the theory before him.Work in pairs.Read the passage again and fill in the following form.Before Copernicus’theoryCopernicus’ theory1.God made the earth.2.The earth was the center of the solar system. 1.The sun is the center of the solar system and the planets go around it except the moon.2.The earth is spinningas it goes round thesun.(Two minutes later.)T: Have you found out the different theories?Who’d like to have a try?S: Before Copernicus’ theory, they believed God had made the earth, so it was the center of the solar system.T: Very good.What about Copernicus’ theory?S: Copernicus found that the sun is the center of the solar system and the planets go round it except the moon.T: That’s right!Anything else?S: He also found the earth is spinning as it goes round the sun.T: Great!(Show the complete form to the students and let them read it.) Just now, we knew Copernicus didn’t publish his theory immediately he found it.Can you tell me why?S: Because he didn’t want to be attacked by the Christian Church.He published it manyyears later.T: Yes.At that time, anyone who wanted to challenge the theory of the Christian Church would be punished, even sometimes be sentenced to death.If you were Copernicus, would you have hidden your theory so for many years?Please give a reason.(Two minutes later.)T: I’d like to know about your ideas.Are you ready?Any volunteers?S: If I were Copernicus, I would have done the same, because at that time, people didn’t enjoy the freedom of speech.Whoever challenged the Christian Church would be punished.While there is life, there is hope.There would be more chance for me to make my theory known to the public.T: It sounds reasonable.Thank you.Anyone else?S: If I were Copernicus, I would have published my ideas as soon as I found them.Since I found my ideas were right, I wouldmake them known to more people, regardless of danger. As a scientist, I should be brave to challenge and devote myself to science.Ss: ...T: You have done a very good job.I appreciate your good ideas and opinions.Step 7 PractisingT: Since we have learned the whole passage, I’d like you to do some practice.(Show the following on the screen.)1.Say something about Copernicus.Copernicus____________________.2.Make up a dialogue between Copernicus and one of his friends.Copernicus showed his ideas privately to his friend and his friend encouraged him to publish his ideas.T: First please say something about Copernicus.Give as much information as possible about him by making sentences beginning with Copernicus.S1: Copernicus is a Poland astronomer.S2: Copernicus found the earth is not thecenter of the solar system.S3: Copernicus didn’t publish his theory until 1543.S4: Copernicus made a great contribution to astronomy.Ss: ...T: I’m deeply impressed by yo ur sentences.You are excellent.From the passage we know Copernicus showed his theory to his friends and his friends encouraged him to publish his theory.Please make up a dialogue in pairs based on this situation.We will hold a competition to see which group acts the best.(After a few minutes, the teacher gets several pairs to act it out and decides which group is the best one.)Step 8 WritingT: Just now we learned that Copernicus didn’t publish his ideas as soon as he found his theory.We also talked about what you would have done if you were Copernicus.Now write a short letter asking Copernicus to publish hisideas so everyone can read them.First you need to collect your ideas.There are some suggested information on Page 7.Then you need to arrange these ideas.There is a plan for it.Beginning: Tell Copernicus who you are and why you want him to publish his ideas.Paragraph 2: Reason 1 and evidence.Paragraph 3: Reason 2 and evidence.Summing up: Ask him to think again about publishing his ideas.(Give Ss some time to do it.Ask them to draw an outline first, and it will help them to develop their writing skill.The passage will be clear.If they have finished writing, get them to exchange with their desk mates.Finally ask some to read their writings to the whole class.While doing this, the teacher can design a competition to arouse their excitement.)Step 9 HomeworkT: You did very well in class.There’s the homework for you.1.Preview the reading passage andunderline the phrases you think important and useful.2.Finish the writing if you haven’t finished and improve it if you have.The Design of the Writing on theBlackboardUnit 1Great scientistsPeriod

ActivitiesThe theme of the activity is“a great scientist in our eyes”.G et the students to work in groups and introduce a great scientist in their minds.First, they need to decide which scientist they think is the greatest.Then, collect as much information as possible about the scientist, such as his/her life, achievements, and so on.In the end, each group presents it to the whole class.The activity is designed to arouse the students’ interest in science, cultivate their team spirit and learn something from these great scientists.It also helps them learn to search for information and organize it well.Reference for TeachingNicolaus CopernicusBorn on Feb.19, 1473, in Thorn (Torun), Poland, Nicolaus Copernicus was destined to become, through the publication of his heliocentric theory 70 years later, one of the seminal figures in the history of scientific thought.The son of a prosperous merchant, he was raised after his father’s death by a maternal uncle, who enabled him to enter the University of Krakow, then famous for its mathematics, philosophy, and astronomy curriculum.This experience stimulated the young Copernicus to study further liberal arts at Bologna (1496-1501), medicine at Padua, and law at the University of Ferrara, from which he emerged in 1503 with the doctorate in canon law.Shortly afterward he returned to Poland and eventually settled permanently at the cathedral in Frauenberg (Frombork), less than 100 miles from hisbirthplace.Through his uncle’s influence he had been elected a canon of the church even before his journey to Italy.Copernicus not only faithfully performed his ecclesiastical duties, but also practiced medicine, wrote a treatise on monetary reform, and turned his attention to a subject in which he had long been interested-astronomy.By May 1514 Copernicus had written De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres, 1543).This classic work challenged the geocentric cosmology that had been accepted since the time of Aristotle.Copernicus proposed that the earth goes round the sun with the other planets.The new theory that Copernicus espoused in De revolutionibus exhibits a peculiar mixture of both radical and conservative elements.In the midst of his radical reordering of the structure of the universe, Copernicus still adhered to the ancient Aristotelian doctrines of solid celestial spheres and perfect circular motion of heavenlybodies, and he held essentially intact the entire Aristotelian physics of motion.Moreover, with significant innovations, he clung to the Ptolemaic representation of planetary motion by means of complicated combinations of circles called epicycles.Although Copernicus realized that his theory implied an enormous increase in the size of the universe, he declined to pronounce it infinite.These aspects of the Copernican treatise do not mitigate the novelty or the impact of the final theory, or the author’s firm conviction that his system was an accurate representation of physical reality.Rather, they indicate the scope of the work that lay ahead and that was effectively addressed in the next century when Kepler determined the ellipticity of planetary orbits, Galileo formulated his new concept of motion, and Newton espoused his theory of universal gravitation.The enunciation of the heliocentric theory by Copernicus marked the beginning of thescientific revolution, and of a new view of a greatly enlarged universe.It was a shift away from the comfortable anthropocentrism of the ancient and medieval world.A scientific theory that reflected so profoundly on humanity was not welcomed by the church, and it was only after the publication (1540) of Narratio prima (A First Account), by an enthusiastic supporter named Rheticus, that the aged Copernicus agreed to commit to print the theory already outlined in 1514.An undocumented, but often repeated, story holds that Copernicus received a printed copy of his treatise on his deathbed.He died on May 24, 1543.Shenzhou Ⅵ touches downBEIJING, Oct.17 (Xinhua/)—The return module of China’s second manned spacecraft Shenzhou Ⅵ has returned to the Earth, and theastronauts are safe.The module and astronauts touched down in the main landing field in Central Inner Mongolia Autonomous Region at 4: 33 A.M.Monday after a five-day flight.Fei Junlong got out of the return module by himself first, followed by Nie Haisheng.The two said they were in good condition when answering questions from journalists.The two People’s Liberation Army colonels received a hero’s welcome.Jubilant residents in Nie’s home town in central Hubei province set off firecrackers and performed traditional lion dances.Fei’s mother wept on learning of his safe return, and his father declared, “The motherland is so great!”State television showed the astronauts emerging from Shenzhou Ⅵunaided, pausing atop the charred reentry craft to wave to the recovery team.Chen Bingde, chief of China’s mannedspace project, declares the mission a complete success.The return moduel landed one kilometer away from the target, and six kilometers from the Shenzhou V’s landing site.The two men are expected to be taken by a helicopter to a local airport to board a flight to Beijing.Both will be in isolation for observation for 14 days after the mission, but family members will be allowed to visit, the Beijing Youth Daily newspaper said Sunday.Fei and Nie blasted off Wednesday on China’s second manned space mission.It came almost exactly two years after China’s first manned space flight.China is only the third country to send humans into orbit on its own, after Russia and the United States.State television showed scores of techniciansmonitoring the landing at computer screens at a Beijing control center.They showed no reaction when an announcer said the capsule had landed but broke into cheers after word came that the astronauts were safe, the Associated Press reported.Chinese leaders including the top legislator Wu Bangguo were shown on television watching the landing from the control center.The mission had“accomplished the planned experiments and accumulated valuable technical data, ”Xinhua s aid Sunday.“We feel good, our work is going smoothly and our life is happy, ”Fei was quoted as saying Sunday evening before the craft began its re-entry maneuvers.“We will do our utmost to fulfill the mission.”“We’re grateful for the deep love and concern by all Chinese people, the Hong Kong, Macao and Taiwan compatriots, ”Nie said.Shenzhou 6 orbited the Earth 76 times andtraveled more than 1.9 million miles.The mission was substantially longer and more complex than the 2003 flight, when astronaut Yang Liwei orbited for 21 1/2 hours before his capsule landed by parachute.。

Teaching Important Points
Get the students to learn different reading skills, especially gist reading and comprehending beyond lines.
Teaching Difficulties
Reading skills are very important for senior students.For the first reading, we intend to cultivate Ss’s kimming ability and scanning ability.First ask the students to scan it and tick out what...are mentioned in the passage.Then let the students read fast to find out the main idea of each paragraph.In order to stimulate Ss to take part in the class activity more actively, the teacher can organize a group competition to see which group can finish the task fastest and best.For the second reading, the students are expected to know some details about the ter on, the teacher will present some questions for the students to answer and at the same time they are asked to finish filling in the chart.The third time is to read for further information.This part is designed to get Ss into the habit of reading a passage as a whole, that is, to get the general idea.Another
