Unit 4 Global Warming 教学设计1-公开课-优质课(人教选修6精品)

Unit 4 Global warming教学案1教材分析Ⅰ.教学内容分析本单元的中心话题是人类当今面对的环境问题,主要探讨了“全球变暖”和“节约能源”等方面的问题。

由于人类过多使用不可再生能源,大气中二氧化碳的含量逐年增加,导致全球气温上升。

通过学习本单元,让学生了解能源分为“不可再生能源”和“可再生能源”,帮助学生树立“节约能源、保护环境”的主人翁意识。

语言知识和语言技能主要围绕“全球变暖”和“节约能源”这一主题设计的。

“热身”(Warming up) 部分要求学生列举家中、学校或其他地方使用能源的物体,指出这些能源的来源,并尽可能多地列举不同的能源。

能源可分为两类:一类是可再利用能源;另一类是一次性能源。

把前面列举的能源按能否再利用这一标准进行分类。

本部分提供了六幅图片,教师可以从识图开始组织教学。

还可以让学生搜集一些其他相关图片。

这六幅图分别为:风力(wind power)、燃煤发电站(a coal power station)、炼油厂(an oil refinery)、原子能发电站(a nuclear power plant)、太阳能接受器(solar panels)、水坝(a hydro dam)。

“读前”(Pre-reading) 部分首先介绍什么是温室、它有什么作用,然后要求学生讨论大气中温室气体的作用。

温室是由玻璃构成的建筑,主要用于花果蔬菜的培植。

温室是由玻璃构成的建筑,主要用于花果蔬菜的培植。

温室能阻止热量散发,因而能帮助植物度过寒冷的时期。

该部分的讨论有利于学生预测课文内容和理解阅读课文中的温室气体效应。

“阅读”(Reading) 部分是一篇杂志文章,主要讲述了地球温度上升的现象和原因。

20世纪中,地球的温度上升了华氏1度。

这看上去是一个很小的数字,但相对于自然界的其他现象来说,这个增长速度是迅猛的。

这种现象是自然发生的还是人为的?这个问题引起激烈的争论。

许多科学家认为,这种变化是人类燃烧矿物燃料所致。

What does it mean?Greenhouse gases (GHG) are gaseous components of the Array atmosphere that contribute to the greenhouse effect .Themajor natural greenhouse gases are water vapor, whichcauses about 36-70% of the greenhouse effect on Earth(not including clouds): carbon dioxide, which causes between 9-26%; and ozone,which causes between 3-7%(note that it is not really possible to assert thatsuch-and-such a gas causes a certain percentage of the GHE, because theinfluences of the various gases are not additive .The higher ends of the rangesquoted are for the gas alone ;the lower end ,for the gas counting overlaps). Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrousoxide, and ozone. Certain human activities, however, add to the levels of mostof these naturally occurring gases.Very powerful greenhouse gases that are not naturally occurring includehydrofluorocarbons(HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which aregenerated in avariety of industrial processes.Each greenhouse gas differs in its ability to absorb heat in the atmosphere.HFCs and PFCsare the most heat-absorbent.2. Individual workGet Ss to answer these questions individually. Then let them discuss theanswers.(1) Who wrote the magazine article? What is the name of the magazine?(2) What are the names of the three scientists mentioned in the article?(3) What do they think about global warming? Do they agree with one another?(4) What are the two graphs about?(5) What is the main topic of the article?Step 3. Reading1. SkimmingPurpose: To get a brief understanding of the text.Read through the text, preferably the first and the last sentences of each paragraph and write the key sentence of each paragraph.Key sentences of each paragraph:(1) A debate over whether it is human activity that has caused the global warming or whether it is just a natural phenomenon.(2) Many scientists believe people have caused the increase in the earth’s temperature.(3) The increased extra amount of carbon dioxide traps more heat energy causing the global temperature to go up.(4) The levels of carbon dioxide have increased greatly over the last 100 to 150 years.(5) There are some different attitudes towards the causes of this increase in carbon dioxide.(6) Over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius but it could be as much as 5 degrees Celsius.(7) An increase of five degrees would be a catastrophe.(8) Future warming would cause the sea level to rise by several meters.(9) Some predict any warming will be mild with few bad environmental consequences.(10) More carbon dioxide is a positive thing.(11) No one knows what the effects of global warming will be.2. ScanningPurpose: To get Ss to have some details in the text.Read the article carefully. Are these statements true or false? Write a T for each true sentence and an F for each false sentence.(1) The temperature last century didn’t increase much. ( )(2) Everyone believes that global warming is caused by the activities of humans. ( )(3) Janice Foster believes that burning fossil fuels causes global warming. ( )(4) Natural gas is a greenhouse gas. ( )(5) Carbon dioxide is a byproduct of burning fossil fuels. ( )(6) People accept Charles Keeling ’s data because he took accurate measurements. ( )(7) Flooding could be one of the effects of future global warming. ( )(8) George Hambley believes scientists are just guessing about the effects of global warming.( )(9) Geroge Hambley is worried about the effects of carbon dioxide on plant growth. ( )(10) It is clear what the effects of global warming will be.Suggested Answers:(1) F (2) F (3) T (4) F (5) T (6) T (7) T (8) T (9) F (10) F3. ListeningPurpose: To train Ss listening ability.Listen to the tape and follow it in a low voice.4. Group workSs are divided into four groups. Each group is supposed to read through eachpart and then discuss them.Part 1 (Paragraph 1)compare 比较●常见用法:① compare…with…把…和…比较Compared with him, I am fast.② compare…to…把…比作…Life is often compared to voyage.(2) come about发生How did it come about? 那事是怎么发生的?●常见词组:come across 偶遇;碰到come round 恢复知觉,come along 进展;进行come to 涉及;到达;共计come out 公开;问世;出版come to oneself 恢复知觉come up with 想出(4) phenomenon n 现象It is only a social phenomenon, but not a phenomenon of nature.

Lesson5Teaching ProcedureEco-CarsⅠ.Introduction of the materialThe title of this lesson is"Eco-Cars."We see and hear the word"eco"almost every day.Does anybody know what"eco"means?When you hear the word"eco,"what does it remind you of?(Ask students.)Maybe"eco"comes from the word ecology.(Write it on the board.)Ecology is the relationship between living things and their surroundings or environment.For example,ecology is the relationship between us and nature,between you and the trees,flowers and wind that blows through your hair.In this lesson,we'll learn about cars that are eco-friendly,cars that are friendly to the earth.And at the end of the lesson we will discuss"Global Warming."By the way,are you eco-friendly?Ⅱ.Teacher explains idioms,phrases and structures covered in the text.(using a Supplementary Handout) Look at your Supplementary Handout.Let's read the example sentences.(Teacher model-reads the example sentences and has students repeat several times,checking the pronunciation of the new words in the sentences.)(Teacher goes on,following the same reading procedure.Ask easy questions so that students can answer using the expressions in the target example sentence.)Do you like fruit?What kinds of fruit do you like?(Pick some students,reminding them to include theexpression"such as.")Do you like animals?What kinds of animals do you like?Line6,"be friendly to~."(After reading,ask the following questions reminding them again to use the key expression.)Is a bicycle friendly to the environment?Is a car friendly to the environment?(Don't ask for the reasons.)Line11,"go for a drive."What would you like to do on a fine day like today(on a cloudy day like today),go for a drive or study in your room?Now,look at the box in the Handout.I'll give you5minutes for silent reading to understand the rules of this grammar.(When the time is up,have students repeat each example sentence after the teacher.)Let's practice how to use this expression.Referring to the example sentences numbered from①to⑥,make5new sentences.(Give time for this task.When the time is up,pick a couple of students from each row to write their sentences on the board.Teacher corrects mistakes with the rest of the class watching.)Line16,"as~as possible."(Follow the same reading procedure with pronunciation check.)Line18.look at the box.You have3minutes for silent reading to understand the rule.(When the time is up,have students repeat the example sentences.)Line26,"take a look at~."(After reading the example sentence,say the following;)Take a look at my pants!They are from UNIQLO.It's the biggest size available at UNIQLO.Say something to me using this expression.(Pick some students.)(As for the next3expressions"make use of","make good use of"and"come to a stop,"the teacher reads the example sentences for students to repeat along with pronunciation check.)Line42,"get~."(Just read the example sentence and have students repeat.)Look at the box.You have3minutes for silent reading.(When the time is up,have students repeat the example sentences.)(As for the next2expressions,follow the same reading procedure.)Look at the last box.You have4minutes for silent reading.(When the time is up,have students repeat the example sentences.) Let's practice how to use this expression.I want everybody to make one sentence using this expression.You have5minutes.(Pick some students to write their sentences on the board for the teacher to check.)(For the next7expressions,follow the same reading procedure.)Line67,"play a~role in---."(After reading the example sentence,ask the following questions;)Who played an important role in the Meiji Restoration?(Write明治維新on the board.)(Write several people's names on the board to make it a multiple-choice s to be written on the board are;夏目漱石・福沢諭吉・坂本龍馬・坂本金八)(Have students answer the question above in a full sentence.)In this class who is going to play an important role in planning a Christmas party?When it comes to planning a party,who will lead the class?Line68,"in order to~","in order not to~."(After reading the example sentences,ask why-questions and have students answer using "in order to"or"in order not to.")Now,I'll ask questions.You must answer using either"in order to"or"in order not to."Why do you study English?Why do you have a cell phone?Why do you set your alarm clock in the morning?〈4th Period〉Ⅰ.Prior to teaching with the text handout,Teacher gives students background information on"Global Warming."Before we read the text,we need to know about"Global Warming."When we have learned about"Global Warming,"it will be easier to understand the text.(Write"Global Warming"on the board.)What does"globe"mean?Does anybody know?(If there is no reaction,have students use a dictionary.)Yes,the globe means the earth,the planet earth.Now that everybody knows what globe means,then what is"Global Warming"?Can anybody explain what"Global Warming"is?(If one student cannot give a full explanation,have other students help.)(Eventually,the teacher explains it in easy English.)In recent years,it's hotter in summer and it doesn't get so cold in winter.It is because of"Global Warming."What's"Global Warming"in Japanese?Does anybody know?Now,I want you and the person next to you to think;"If the effect of Global Warming became really bad in Hokkaido,what would happen to your life and life styles?"You have5minutes.(Pick some pairs to present their ideas and discuss it with the rest of the class.)〈5th+6th+7th Period〉Ⅰ.Students'silent reading of the text(Give students15minutes to read and understand the passage.The use of a dictionary is not allowed until the last5minutes.)Ⅱ.Reading of the text and pronunciation check(led by the teacher)First,I'll read the whole passage a little slow.You listen carefully and try to guess the content.For the second reading,everybody repeat after me.We'll check pronunciation as well.Ⅲ.Have students guess the content with the teacher's assistance.Explanation of the content by the teacher(From Line1to Line12,Teacher just goes on as he or she reads the sentences as the part is easy to understand.)Line12says"when we drive,our cars emit gases.""Emit"means"give off."For example,kame-mushi(a kind of bug)emits a bad smell when you touch it.A lightning bug,or hotaru in Japanese emits light.Line14,"exhaust"is gas that comes out of a car.For an explanation on the different gases,look at the glossary at the bottom of the handout.(Go on as you read.)(Teacher helps students better understand the content by simplifying or rephrasing the sentence,or by giving specific examples or by asking answer-inducing questions.)Line15."An eco-car is a car developed to emit as little of these harmful gases as possible."can be rephrased into"People have made a car which emits very little harmful gases.The car is called an eco-car."Line18."A number of improvements are being made to the typical gasoline cars."means"We are improving gasoline cars in many ways."At the same time,we are making cars which don't use gasoline.(Go on as you read,clarifying the differences between"natural gas cars","hybrid cars"and"electric cars.")(Ask questions about the drawbacks of each car.)Line43,"the fuel-cell car."Can anybody explain how the fuel-cell car runs?What does it emit when it runs?What drawbacks does the fuel-cell car have?There are two drawbacks.(Go on as you read.)(From Line56to Line62,give students10minutes to refer to the Supplementary Handout to understand the content,since this part is beyond understanding even with the help of the teacher's simplification or rephrasing.)(Go on as you read.)〈8th+9th+10th+11th Period〉Ⅰ.Simplification of the passage and presentation on"Global Warming"(by students)*Teacher instructs on how to express thoughts and how to write a passage using easy English expressions.(This is not for evaluation.)・Why is the earth getting hotter?・What are the causes of Global Warming?・What human activities are to blame?・Are you helping to accelerate Global Warming?・What can you do to stop it?。

Unit 4 Global warmingWarming up and pre-readingTeaching goals (教学目标)1. Enable the students to talk about different sources of energy and express their own ideas.2. Help the students learn how to give their ideas about the use of energy.Teaching important points 教学重点Train the students’ speaking ability by talking about global warming.Teaching difficult points 教学难点How to help the student carry out the task of speaking.Teaching aidsMultimediaTeaching proceduresStep ⅠgreetingT: Good morning, everyone.Ss: Good morning, teacher.T: Sit down, please.Step II lead inT: Now late autumn is approaching, but the weather here is still quite hot, do you know why? What causes such bad weather?S1: …S2:…T: Yes, great, today we will talk some thing about it. Please turn to page25 and look at the topic of this unit, do you understand it? How to understand it in Chinese? Now let’s watch a film first(play the film for the students)and then appreciate some pictures.(show the pictures on the screen) what does the movie tell us?(The movie tells that the temperature heats up due to global warming. The Ice Age is coming to an end.)(Animals discover that the miles of melted ice will flood their valley, they try to avoid the trouble .)Eventually, they succeed.Look at the pictures and think about the following questions.Think about:What causes the global warming? Human activity or a random but naturalphenomenon?(watch a video)T: When we talk about this problem, we naturally link it to the use of energy and the environmental pollution. But firstly and importantly, energy makes a great difference to our lives. we depend on energy to do many things in our daily life. Some people even say we could do nothing without energy. Can you tell me what we use energy for?Things that use energy around us or at any other places:hair-dryer television air-conditionerCar washing machine fridgeSa: Energy lights our cities.Sb: Energy heats our buildings.Sc: Energy entertains us. With the help of electricity, people have got a lot of fun from watching TV, playing computers and so on.Sd: There are many other electrical appliances that make our life more convenient and comfortable such as washing machines, microwaves, air conditioners and so on. Se: Today energy also helps people realize many so-called dreams in the past. For example, people can “fly”from one place to another by plane which runs on energy. Sf: It’s true. In fact, not only planes but also cars, ships and trains run on energy.T: Well done. All that you’ve just said is right. So it seems that energy plays a very important role in the modern world. Then where does all the energy come from? Open your books and turn to page 25. Look at the pictures on this page. They may help you find out the answers.Step III warming upT: Where does all this energy come from?From the following pictures(on page 25, show them on the screen), you will know where all this energy comes from.T: Who’d like to tell us your answers?Sg: Wind power.Sh: Coal power.T: Right. Is there any difference between them?Si: Yes. Wind will never run out while coal is a limited source.Step IV DiscussionAn energy source is “renewable”when supplies of it never run out and “non-renewable”when one day they will run out. Which energy sources on your list are renewable and which are non-renewable? Fill in the following blanks.Group workSources of energy Renewable /non-renewablecoal non-renewableoil non-renewablenatural gas non-renewablewind (wind power) renewablesun (solar energy) renewablenuclear energy non-renewablewater (hydro-electric水力发电) renewableplant waste (biomass生物量energy) renewablehot springs (geothermal energy地热能) renewablethe sea (tidal energy潮汐能) renewableT: It ’s true, such as coal, will definitely run out one day. Energy of this kind is called non-renewable sources. Please think of as many sources as you can and decide which energy sources on your list are renewable and which are non-renewable. Step V pre-readingT: What is this?What is a greenhouse made of and used for?A greenhouse is made of glass and is used for growing plants, especially during cold weather.How does a greenhouse work?The air inside is warm because the glass traps the heat from the sun and keeps it from escaping. This makes the greenhouse heat up and so the plants can grow throughout the cold period.we call global warming “greenhouse effect(温室效应) ”.大气能使太阳短波辐射到达地面,但地表向外放出的长波热辐射线却被大气吸收,这样就使地表与低层大气温度增高,因其作用类似于栽培农作物的温室,故名温室效应。

1. Knowledge Aims:
Let students know something about global warming by reading this text.
2. Ability Aims:
Enable students to improve their reading ability by using different and appropriate strategies and tasks.
3. Moral Aims:
Let students know more about global warming and raise their awareness of environmental protection.
Teaching Important Points:
Make students read the text to get some specific information about the reading passage.
Make students do some tasks to practice their reading ability. Teaching Difficult Points:
How does the teacher use appropriate strategies and tasks to develop students’ task-based reading ability?
Teaching Methods:
1 Task-based teaching method
2. Cooperation teaching method
3. Individual, pair, and group work.
4. Fast and further reading
5. Discussion
Teaching Aids:
Multi-media
Teaching Procedures:
Step1. Warm up
Students look some pictures about “Earth is like a paradise”.
Step2. Pre- reading
Let the whole students discuss two questions to guess the meaning of the title and the general idea of the text.
What makes the Earth become so hot?
What problems does it result in?
Then, show some pictures to them.
Step3. While-reading
1.Fast-reading
Play the tape of the text to the students, ask them to go through the text quickly and underline the strange words on the screen.
Then guess the correct meaning of each new word.
2.Further-reading
Before reading again, let students read through the heads on the screen . Then ask them to skim the text and match the heads with the paragraphs.
Step4. Post- reading
1. Show students a form about the text; let students get more
detailed information to fill in the missing word of each blank.
After few minutes, ask some students to write these missing words on the blackboard.
2. Read the text and answer these questions.
1) What is global warming?
Global warming refers to an average increase in the Earth’s temperature that, in turn, leads to climate change.
2) What human activities are causing global warming?
Industry, agriculture, the cutting down of forests, the increase in transport and the burning of fuels are causing global warming.
3) By how much has the global average temperature increased in the
last 100 years?
By 1ºF (One degree Fahrenheit)
4) Are greenhouse gases necessary for life on Earth?
Yes, they are. Because they trap heat from the sun in the Earth’s atmosphere. Otherwise the Earth would be cold and unsuitable for
life.
5) How can we help solve the problem of global warming?
We can make small changes like taking public transport, recycling, using low-flow shower heads, buying light bulbs that use less energy, using recycled paper and switching off the lights when we leave a room.
Step6. V oice your opinion
What will you do every day to help reduce greenhouse gases?
Show an example to students, and then ask students to imitate this example to organize a dialogue about this question with their partners..
Step7. Homework
♦Read the text after class.
♦Try to recycle something to make your own contribution. Then based on these actions, write a composition to share your experience with us.
Step8. Record after teaching。
