2019-2020年高中英語 Period1 Introduction and writing（Module4 Great Scientists） 教案 外研版必修4 Introduction In this part,we will lead in the topic by talking about some scientists.The teacher can show the students some pictures of scientists on the screen,such as Albert Einstein,Archimedes,Marie Curie,Qian Xuesen.Make sure the students know them and encourage them to say as many things about them as they can.That’s the lead-in and also Activity 1 in the introduction.In Activity 2,we’ll learn some words related to science.In this part,let the students match the subjects with their definitions.Pair work can be involved in Activity 3.Ask the students to work in pairs and write some facts about a famous scientist.(The teacher had better ask the students to collect some information by surfing the Internet or reading some magazine ahead of time.) Vocabulary and Reading The passage mainly tells us the story of Yuan Longping—the father of hybrid rice.The teacher may ask the students to read the text fast to get the main idea of each paragraph.Then do some careful reading to make sure the students understand the passage better.At the same time,we’ll deal with some exercises including some word study.The teacher may show them on the screen,such as staple,yield,sterile,hybrid,etc.By guessing from the whole context they will have a good sense of enlarging their vocabulary and this is very important in learning a language.While reading this passage,some reading strategies are necessary:skimming—fast reading to find out the general idea of the passage as well as the answers to one or two questions;scanning—careful reading to look for important facts;guessing—try to guess new words from the context,understand the author’s attitude and ideas from the context and understand the intention. In the teaching of reading,the teacher can organize different reading activities according to the content of the text on purpose to train the above reading strategies and help them develop good reading habits from the very beginning. Function Function in this module is talking about numbers,which include big numbers,fractions and percentages.The students can finish Activities 1 and 2 individually and check the answers with the whole class.As for activity 3,pair work or group work is better.Let the students dictate some numbers to their partners to consolidate what they learned.After that,the teacher can give them a quiz to make sure the students can distinguish different numbers correctly and can read and write them in the correct way. Grammar 1 In grammar 1,we’ll revise the passive voice of present tense,past tense,future tense and present perfect tense.There are four activities for the students to practice.Through Activity 1,the teacher will know if the students can tell passive voice from active voice and if they can distinguish the sentence tense.In class,the teacher should give the students more chances to speak English. Listening Activity 1 is an oral job.The teacher may give the students one minute to have a quick look at the picture on Page 36 and then describe what is happening.The teacher can ask two or three students to answer this question.In finishing Activities 2 & 3 more efforts may be involved,and therefore the teacher had better play the tape twice.After listening we’ll do a word exercise,that is Activity 4,match the words with the meaning.It is a good way to consolidate new words. Reading and Writing This part is very important and useful for the students to practice writing.At the beginning,we’ll learn the new words:best-seller cosmology,diagnose,disability,motor neurone disease,and victim.In activity 2 there are three disordered paragraphs about scientist Stephen Hawking.Then make sure the main idea of each paragraph in activity 3.Activity 4 gives us the notes about Albert Einstein in the order of time,which is often the main character of introducing a person.At last,choose some information about him to write three short paragraphs about Albert Einstein.The beginning is given in Activity 5.Time permitting,the teacher may encourage the students to report what they write.If possible,present the students writing on the screen.Mistakes can be corrected now. Grammar 2 In this part,the students will learn to use by+-ing form.Firstly,in Activity 1 make sure the usage of this form.It usually works as adverbial,and means “using some way”.This form is not difficult.We are sure that after the practice in Activity 2,the students can master this form correctly. Pronunciation;Speaking and Everyday English The stress in long words is also the emphasis.The stress in a long word may　e at the beginning,in the middle,or at the end.In this part,we’ll do some practice about that.In speaking,we’ll play a game of guessing scientists’ names.First,the students may think of a famous scientist or inventor and some information about his life.Some questions about scientists are given as examples.Then work with another pair.Guess who pair B is describing by asking yes or no questions.Pair work will be involved in this part and more practice will be encouraged.Everyday English we’ll learn in this module is as follows:breakthrough,nickname,Pass and well done. Cultural Corner In this part,we’ll learn something about rockets.After studying the text,the students will be clear about the history and development of rockets.This supplementary reading will enrich the students’ knowledge of some scientific invention. Task After speaking,write down your notes about the scientist.Then prepare a radio programme about the life of a famous scientist.If possible,record your radio programme.If not,write a passage about the famous scientist,and then report it to the whole class. Module File This part is a summary of this module.It may help the students to know whether they have mastered the main points or not.If time permits,the teacher may have a revision of this module by analyzing this part and consolidate it with some exercises. Six periods for teaching Period 1:Introduction;Writing Period 2:Vocabulary and Reading Period 3:Function;Grammar 1,2 Period 4:Listening;Pronunciation;Speaking Period 5:Everyday English;Cultural corner;Task;Module file Period 1　Introduction;Writing The General Idea of This Period In this period,we will lead in the topic by talking about some scientists.The teacher can show the students some pictures of scientists on the screen,such as Albert Einstein,Archimedes,Marie Curie,Qian Xuesen.Make sure the students know them and encourage them to say as many things about them as they can.That’s the lead-in and also Activity 1 in this part.In Activity 2,we’ll learn some words related to science.In this part,let the students match the subjects with their definitions.Pair work can be involved in Activity 3.Ask the students to work in pairs and write some facts about a famous scientist.In reading and writing,we’ll learn a passage about Stephen Hawking and learn to write three short paragraphs about Albert Einstein.(The teacher had better ask the students to collect some information by surfing the Internet or reading some magazine ahead of time.)

T:Okay,let’s look at the words in the box in Activity 2.Then match the words and definitions.First,read the words after me and pay attention to their pronunciation and stress!Biochemistry,biology,botany,chemistry,genetics,physics,zoology.Please match them with their definitions quickly.(After a while,check the answers.) Suggested answers: 1.zoology 2.botany 3.biology 4.physics 5.biochemistry 6.chemistry 7.genetics Step 3 Writing some facts T:Just now,we share some information about some famous scientist.Which scientists do you know about? Ss:Edison,Newton,Nobel,... T:Good!Can you write down some facts about a famous scientist?There is an example for you.Newton was born in England in the 17th century.He discovered the laws of gravity.Now,work with your partner and write down some facts.(Give the students three minutes to prepare.) Time is over.The teacher can check their work. T:OK,I know you’ve written some information.Who’d like to share your facts? Sa:Marie Curie was born in Poland in 1867.She discovered two radioactive elements,Polonium and Radium and made great contribution to physics and chemistry.She got the Nobel Prize twice in her life.She is a great woman scientist in the world. T:Excellent job!You give us a good example.Anyone else? If time permits,give more students the chance to speak out what they have written down. (In order to do the job well,the teacher can ask the students to search for more information about scientists on the Internet or in a library before class.) Suggested answer for reference: Francis Crick(born in 1916)was a British molecular biologist.He graduated from Cambridge in physics,and was a scientist with the navy from 1940-1947.He then returned to Cambridge to work on the structure of molecules using X-ray crystallography.In 1951,with the American J.D.Watson,he started work on trying to describe the chemical structure of DNA.Using X-ray pictures they eventually described it as a double helix.He and Watson were awarded the Nobel Prize in 1962.In 1977,Crick went to work at the Salk Institute in San Francisco. Step 4 Reading and writing 　 Read through the words in the box and have the students repeat them,paying attention to the words where the stress does not fall on the first syllable:cosmology,creation,diagnose disability,disease. best-seller（暢銷書）　cosmology（宇宙論）　diagnose（診斷） disability（殘疾）　motor neurone disease （運動神經(jīng)元?。?victim（受害者） T:Now let’s e to the following passage,which is about the famous scientist,Stephen Hawking.There are three paragraphs and disordered.Read them and number them in the correct order.While reading,try to get the main idea of each paragraph. __________Victims of motor neurone disease cannot move and cannot speak but their brains may work perfectly.In Stephen Hawking’s case it was discovered that he was a brilliant scientist.Moving in a wheelchair and speaking through a special puter,he has bee the voice of science.__________Stephen Hawking has spent his career at Cambridge University,where he became Professor in 1977.His work was in the area of cosmology and he wrote about black holes in space.His book A Brief History of Time was published in 1988 and is still a best-seller. __________Stephen Hawking is one of the most famous scientist in the world partly because of his scientific discoveries and partly because of his physical disability.He was born in 1942 in Oxford and graduated from Oxford University.In the 1960s he was diagnosed with motor neurone disease. Suggested answers: 2　3　1 T:Let’s e to Activity 3.Write the number of the paragraph.Give the students two minutes to prepare,then collect their answers chorally and individually. 1.This paragraph explains why Hawking is famous.__________ 2.This paragraph talks about Hawking’s personal life.__________ 3.This paragraph talks about Hawking’s scientific career.__________ Suggested answers: 1.The third in the book. 2.The first in the book. 3.The second in the book. T:So much for this passage.Now we read some facts about Albert Einstein,another famous scientist in the world.There are some notes about him,read it and write there short paragraphs about him using the notes given. born in Ulm,Germany,1879 didn’t speak until he was three loved mathematics had the idea of his theory of relativity when he was 16 studied physics in Zurich,Switzerland got a job in an office to earn his living published the general theory of relativity in 1905 became a university teacher in 1909 published the general theory of relativity in 1915 awarded Nobel Prize for physics in 1921 left Germany when Hitler came to power and went to work in the US died in 1955 Suggested answers: Albert Einstein was probably the most brilliant scientist of he twentieth century.Born in Ulm,Germany in 1879,he didn’t speak until he was three,but then developed a strong interest in mathematics as a child.He had idea for his theory of relativity at the age of 16,although he didn’t publish it until 1905,after he had studied physics in Zurich,Switzerland. He became a university teacher in 1905,and published the general theory of relativity in 1915.In 1921 he was awarded the Nobel Prize for physics. When Hitler came to power,Einstein left Germany and went to live and work in the USA.He died in 1955. Step 5 Summary and homework T:First of all,we learned some facts about some famous scientists and also some names of scientific studies.Then we read some facts about Stephen Hawking,a famous disabled scientist and some facts about the famous scientist Albert Einstein.And practise writing.Homework today is to write short passage about a famous scientist.Hand it in today.That’s all for today.Good-bye,everyone.

The Design of the Writing on the Blackboard 　 Module 4　Great ScientistsThe first period biochemistry　biology　botany　chemistry　genetics　physics　zoology Record after Teaching ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ Activities and Research 1.Think of more famous scientists in the world and China and try to say something about them. 2.Search for some information about scientists on the Internet or in a library. Reference for Teaching Background Information Qian Xuesen Qian Xuesen is one of the pioneers of China’s space science.A world-famous expert on aerospace rockets and aerodynamics,Qian has obtained great attainments in the areas of applied mechanics,engineering cybernetics and system engineering and made distinguished contributions to the foundation and development of Chinese aerospace undertaking.He plays a leading role in the research,manufacture and testing of carrier rockets,guided missiles and satellites.Due to research and development led by Qian,China successfully exploded its first atom bomb in 1964,launched its first man-made satellite in 1970,fired its first transcontinental ballistic missile toward the Pacific in 1980,and launched its first manned spacecraft on Oct.15,xx. In 1955,six years later after the founding of New China,Qian Xuesen returned to the motherland.In 1956,Qian put forward “Proposal on the Development of China’s Aviation Industry for National Defense” and assisted Zhou Enlai,the then premiere,and Marshal Nie Rongzheng to prepare the establishment of China’s first missile and rocket R&D structure,the Fifth Research Institute of State Ministry of Defense.In the October of 1956,Qian assumed office of director-general with the fifth research institute.Henceforth,Qian has long been in charge of the chief technological officer with the R&D of China’s missile,rocket and spacecraft,and has contributed great to the establishment and development of China’s missile,rocket and spacecraft undertakings. Marie Curie Marie Curie,Polish scientist,was born in Warsaw,on November 7th,1867,and died in France,on 4th July 1934.Her single name was Maria Sklodowska.In Paris,Marie graduated in Mathematical and Physical Sciences.She got married in 1895 with the French physicist,Pierre Curie.In 1896,H.Becquerel suggested the theme of her Ph.D.thesis the study of natural radiation from uranium salts.During her work,the Curie couple discovered a new radioactive element named polonium in honor to Marie’s homeland.A few months later,they were able to discover radium for the first time.Together with Becquerel,she obtained the Nobel Prize for Physics in 1903.She founded the Radium Institute of Paris,and was the main responsible until her death.In 1911 she was awarded the Nobel Prize for Chemistry. Albert Einstein Albert Einstein was born in Ulm,Germany,in 1879.His father owned a factory that made electrical devices.His mother enjoyed music and books.His parents were Jewish but they did not observe many of the religion’s rules.As a child he always loved mathematics,and he had his idea of the theory of relativity when he was only 16 years old.He published his special theory of relativity in 1905.In 1915,he expanded it to a “General Theory of Relativity.” He changed the way we understand the universe. In 1921,he won the Nobel Prize in Physics.It was given to him,not for his theories of relativity,but for his discovery of the law of the photoelectric effect.This scientific law explained how and why some metals give off electrons after light falls on their surfaces.The discovery led to the development of modern electronics,including radio and television.Albert Einstein taught in Switzerland and Germany.He left Germany when Adolph Hitler came to power in 1933.He moved to the United States to continue his research.He worked at the Institute for Advanced Study in Princeton,New Jersey.Einstein became a citizen of the United States in Nineteen-Forty.Albert Einstein opposed wars.Yet he wrote to President Franklin Roosevelt in 1939 to advise him that the United States should develop an atomic bomb before Germany did.Albert Einstein died in Nineteen-Fifty-Five.He was seventy-six years old. Archimedes 阿基米德（Archimedes約公元前287～前212）是古希臘著名的數(shù)學(xué)家和物理學(xué)家。靜力學(xué)和流體靜力學(xué)的奠基人。公元前287年誕生于地中海西西里島的敘拉古城（今意大利錫拉庫薩）。他的父親是古希臘天文學(xué)家和數(shù)學(xué)家。阿基米德從小深受父親的影響,偏愛數(shù)學(xué),很早就學(xué)習(xí)希臘著名數(shù)學(xué)家歐幾里得（約前330~前275）的《幾何學(xué)原理》。11歲的時候,阿基米德去當(dāng)時著名的文化中心——尼羅河畔的亞歷山大城學(xué)習(xí)。學(xué)習(xí)期間對數(shù)學(xué)、力學(xué)和天文學(xué)有濃厚的興趣。在他學(xué)習(xí)天文學(xué)時,發(fā)明了用水力推動的星球儀,并用它模擬太陽、行星和月亮的運行及表演日食和月食現(xiàn)象。為解決用尼羅河水灌溉土地的難題,他發(fā)明了圓筒狀的螺旋揚水器,后人稱它為”阿基米德螺旋”。公元前240年,他學(xué)成后回到敘拉古,當(dāng)了國王亥厄洛的顧問,幫助國王解決生產(chǎn)實踐、軍事技術(shù)和日常生活中的各種科學(xué)技術(shù)問題。公元前212年,敘拉古城失陷,正在聚精會神地研究科學(xué)問題的阿基米德,不幸被蠻橫的羅馬士兵殺害。 袁隆平 袁隆平 Yuan Longp
