Teacher begins the class by asking: Have you ever seen the movie The Day After Tomorrow? and then let students enjoya short movie clip with the following two questions:① What kinds of disasters have you seen in the film?② Can you guess how they came about (happen)?2. introduce the topic: global warming. And then have a further question:①What other disaster will be caused by global warming?【Designing Purpose】To arouse students’ interest by watching the movie clip and educe the topic, that is global warming. And then by showing a lot of pictures, make students know and understand theterrible effects of global warming, thus making preparations for promoting environmental protection.Step2. While Reading (Individual work)Skimming: Go through the first letter to f ind:① who is the writer?② what are his two concerns?Scanning: Read the second letter and answer the following questions:① Does Earth Care agree with Ouy ang Guang’s opinion that individuals can have no effect?② what are Earth Care’s suggestions?③ Can we carry those suggestions out? Why?【Designing Purpose】To help the students grasp the main information of the two letters by skimming and scanning. While stud ents get the answer to question1, ask them to find the supporting sentence : Together, individuals can make a difference. We do not have to put up with pollution. Guess the meanings of the two italicized phrases according to the surroundings and their understanding.Step3. Post reading (Pair work)1. Discussion: Make students discuss whether they can find more ways or suggestions about reducing carbon dioxide and saving energy in our daily life.Suggested ways:1) Use less hot water 7)Change a light bulb 8)Try car sharing2) Take a shower instead of a bath3) Buy fresh food instead of frozen4) Buy things that are actually in season5) Eat less high fat food like KFC and Macdonald6) Clean filters(过滤器) on your air conditioner.【Designing Purpose】To cultivate students to work in pairs and learn to summarize an opinion and share the knowledge of saving energy in daily life.

Before class, I’ll check your homework first. Mary, would you read your homework to us?Check the students’ homework and have a discussion with the students about the mistakes Mary made. Let the students have a clear understanding about the mistakes and then correct them.Step ⅡWarming upT: As we all know, we depen d 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?Sa: 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.After a while.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.T: It’s true. As we know, an energy source is renewable when supplies of it never run out while some supplies， 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.If necessary, give some words related to the pictures which might be difficult for the students such as oil refinery, hydroelectric power and so on.The teacher should also collect as much information about different sources of energy as possible and show it to the students in class through a computer. In this way, the students will become more interested in this topic and their knowledge on this aspect will be enlarged.Sample answers:Step Ⅲ Listening and DiscussingT: Fromwhat we’ve just talked about, it is clear that energy does a lot of good to us.But every coin has two sides. Is there any negative effect of using energy?Sa: Yes.People use too much energy which is resulting in an increase in carbon dioxide.That is how the global warming comes about.Sb: Andmeanwhile it pollutes the environment.T: It’strue. Many people have realized the problem. Next we’ll do some listeningpractice on this topic. Let’s see what other people think of this issue.Thestudents are asked to read the questions quickly to find out the listeningpoints first. Then listen to the tape twice and give the correct answers.T: Nowplease turn to page 31. Let’s do listening.

Unit 4 Global warming教学目标1) Learn some knowledge about the greenhouse effect and global warming.2) Know the contents of the text well by talking about this topic and reading.3) Discuss the problem of global warming and express your own opinions学情分析There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable(suitable for people to live in). Without it, scientists estimate that the average temperature on Earth would be colder by about 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain(维持) our current ecosystem. In other words，the normal greenhouse effect is a natural process which is to some degree beneficial to us.重点难点Master the main idea of the first five paragraphs by talking about the topic.教学过程活动1 【讲授】Unit 4Teaching procedures:Step I. GreetingsGreet the whole class as usual.Step II. Lead-inLead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.Step III. Analyze two graphs to learn the main idea of the first five paragraphs.From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit. All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.More such burning means more carbon dioxide added to the atmosphere.We can see clearly that the levels of carbon dioxide have increased greatly over the past decades.Higher levels of carbon dioxide means sharper increase of the temperature. The phenomenon is called global warming.There has been a debate towards global warming over the pastyears. Opinions about it vary from person to person.Step IV. Read the whole passage to review the main idea of the first five paragraphs and know the two different opinions. Dr. FosterCarbon dioxide has caused the global temperature to ________. An increase of five degrees would be a ____________ and could be very ________.Possible results: __________________(海平面上升)___________________(洪灾)___________________(恶劣的风暴)___________________(干旱)__________________(饥荒)__________________(疾病的传播)___________________________(物种的消失)George Hambley:Any warming will be ______ with few bad ______________________. More carbon dioxide is a _________ thing, which makes crops __________ more and will encourage _____________________.Step V. Discuss the statement: We should take immediate action about global warming.Requirement: Write down your reasons and possible measures on your learning sheetStep VI. Presentation.Ask some students to read their reasons and possible reasons loudly to the whole class.Step VII. Assignment.Make up a complete composition in groups. The passage should include your point of view, your reasons and your measures.精美句子1、善思则能“从无字句处读书”。

Global warming-Reading教案(新人教版高中英语选修6 unit 4) Pre-reading1. Questioning and answeringAsk students something about a green house. What is it? What is it for? Could you tell the class in English what you know about a green house?A green house is built of glass to be used for growing plants. The air inside the green house is warm because the glass lets in the sun and keeps it from running away. So the air inside is warm and is good for growing plants throughout the cold seasons.2. Introduces students to the topic of the reading passage and the term “greenhouse gases”.3. Do exercises⑴What is the building made of and what its purpose?⑵What’s greenhouse effect?Teaching aims:To read the text “The earth is becoming warmer—but does it matter” and understand what it says.To make students find out some useful words and expressions. Teaching procedures:Step 1. Read the text (Page26)Answer the following questions.1 what is the purpose of the first paragraph?To introduce the topic.2 what are the diagrams for?To illustrate points by providing evidence.3 what is the purpose of the last paragraph of the article?To reflect on the major theme of the text and to predict what might happen in the future.Step 2. Read again for more detailsTo understand the main idea of the text, we are going to read it once again. Write down the key sentence of each paragraph at the same time.Key sentence of each paragraph:A debate over whether it is human activity that has caused the global warming or whether it is just a natural phenomenon.Many scientists believe people have caused the increase in the earth’s temperature.The increased extra amount of carbon dioxide traps more heat energy causing the global temperature to go up.The levels of carbon dioxide have increased greatly over the last 100 to 150 years.There are some different attitudes towards the causes of this increasein carbon dioxide.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. An increase of five degrees would be a catastrophe.Future warming would cause the sea level to rise by several meters. Some predict any warming will be mild with few bad environmental consequences.More carbon dioxide is a positive thing.No one knows what the effects of global warming will be.Step 3. Listen to the tape and then find out some useful words and expressions.。
