教版高中英语必修五阅读课教案设计Unit1 Great ScientistsPeriod 1 Warming up & ReadingI. Teaching Aimsa) Knowledge Aims Students can have a good command of the words and phrases in the reading passage. Students can know the steps on how to conduct a research.b) Ability Aims Students can practice such reading techniques as skimming and scanning. Students can perceive the usage of past principle as attribute and predicative.c) Emotional Aims Students can be encouraged and inspired by the scientific spirits of persistence and carefulness. Students will learn to be rigorous no matter what they do.II. Teaching Key PointStudents can make full use of reading techniques to help them understand the passage quickly and correctly.III. Teaching Difficult PointStudents can map out a certain scientific stage and its related details.IV. Teaching MethodsTeaching based on independent exploring; teaching based on questioning.V. Teaching AidsMultimedia.VI. Teaching ProceduresStep 1. Lead-in and Warming-upWarming UpTask1. Here are eight scientists names. Please answer the following questions with the numbers in front of these names. （3 mins） Charles Darwin t:lz d:wn Gregory Mendel 'reri 'mendl Stephen Hawking 'stivn 'h:k Archimedes :kimi:di:z Marie Curie m:r(:) kjri: Thomas Edison tms edisn Zhang Heng Leonardo da Vinci li:'n:dd vinti(:)( ) 1.

Who put forward a theory about black holes?(Justification: These matching activities can arouse students interest in learning about scientists.)Step 2. PresentationPre-readingTask 1. Ask students to work in small groups of 3 and put the following stages into proper order. (3 mins)Draw a conclusion Think of a method Collect results Make a question Find a problem Analyze the results Find supporting evidence(Justification: This activity can help students to learn new knowledge based on their previous cognition.)While-reading1. SkimmingTask 1. Students are expected to look the passage very quickly and make a choice about its main idea. (2 mins)Whats the main idea of the passage?A. John Snow was a well-known doctor in London.B. The cause of Cholera was polluted water.C. The source of all drinking water should be examined.D. How did John Snow collect, analyze data and find the cause of the disease and solved it.(Justification: This practice can help students to know the gist of the passage.)2. ScanningTask 1. Students will be asked to finish the following questions by taking advantage of scanning. ( 5mins)Q1.When did Dr. Snow think the disease would be controlled?A1. He knew it would never be controlled until its cause was found.Q2. How serious was the disease outbreak in London?A2. The cholera outbreak was so severe that more than 500 people had died in ten days.Q3. Where were many of the deaths in Broad Street?A3. Many of the deaths were near the water pump in Broad Street.Q4. What did Dr. Snow think was responsible for the disease?A4. It seemed the water was to blame.Q5. What did Dr. Snow advised the people in Broad Street do?A5. He told the people to remove the handle from the water pump so that it could not be used.(Justification: This practice will help students to develop their ability of finding relevant information quickly based on the key words in the questions.)Further ComprehendingTask 1. Students need to fill out the following chart based on a careful reading of each paragraph. (6 mins)ParagraphStageGeneral idea1Find a problemThe cause of cholera. 2Make a questionTheory one: Cholera multiplied in the air and dangerous gas floated around until it found its victims.Theory two: When people absorbed cholera into their bodies with meals, their bodies were attacked and soon they died.3Think of a methodTo _prove_ the second theory was correct.4Collect results Some information was _gathered_ on how many people died and where they got water.5Analyse results _Analyze_the water to see if that is the cause of the illness. 6Find supporting evidence With extra _evidence_, it was announced definitely that polluted_ water carried cholera.7Make a conclusionPolluted water spread cholera. “King Cholera” was _defeated.Task 2. Number these events in the order that they happened. (4 mins)_2_John Snow began to test two theories._1_ _An outbreak of cholera hit London in 1854._4_ _John Snow marked the deaths on a map._7_ He announced that the water carried the disease._3_ John Snow investigated two streets where the outbreak was very severe._8_ King Cholera was defeated._5_ He found that most of the deaths were near a water pump._6_ He had the handle removed from the water pump.(Justification: These first activity help students understand the general idea of each paragraph, and the second one is designed to help students get clearer about the structure of the passage.)Step 3. DiscussionTask 1. Students need to discuss in groups of 4 the two following questions. (5 mins)Q1. What similarities do Cholera and Covid-19 have? Use the chart to help you organize your ideas.similaritiesSpreading way(s)fatality ratepreventionCholeraCovid-19Q2. How to protect ourselves against Covid-19? You can get some hints from the given expressions. (4 mins)medical mask; vaccine; serving chopsticks; avoid crowded place.(Justification: Discussion can motivate students to brainstorm as many ideas as possible and cultivate their spirit of team cooperation.)Step 4. Summary (1 min)Today we have learned the steps/procedures/stages on how to prove a new idea in scientific research and how John Snow defeats Cholera.(Justification: Making a summary can empower students to better memorize what they have learned in a certain English class.)Homework (1 min)Try to find as much information as you can about a scientist you admire most and summarize why he/she can make great achievements.(Justification: This homework will help students to learn more about a chosen scientist and train their abilities of reading and summarizing.)Blackboard Design Unit1 Great ScientistsPeriod 1 Warming up & ReadingScientific stages: Important words:Find a problem put forward Make a question defeatThink of a method attendCollect results expose Analyse the results cureFind supporting evidence challenge suspect第 6 页 共 6 页学科网（北京）股份有限公司
