Unit 4Global warming错误!本单元的中心话题是人类当今面临的环境问题，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。
本单元的主要教学内容如下表所示：Period 1 Warming Up，Pre－reading，Reading and Comprehending错误!教学内容分析This is the first teaching period of this unit。
The central part of this period is the reading passage with the title of “The Earth Is Becoming Warmer—But Does It Matter？”talking about the global issue which has a great effect on human beings’ life。
Warming Up gives six pictures to help students list the sources of energy they can think of in our daily life。
Then they will be led to discuss which energy source is “renewable"and which is “non－renewable"．This part is designed to help the students to recall their background knowledge about energy and prepares students for the whole unit.Pre－reading provides a picture of a greenhouse and then tells us what a greenhouse is and what “greenhouse gases” are。

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。

Learning ability goals 学能目标Help the students learn how to give their ideas about the use of energy.学情分析学生对全球变暖问题很感兴趣，但是对于这一话题用英语表达还存在严重不足，所以这是一个很好的让学生学习这方面词汇及句子表达的好机会。
重点难点Enable the students to express agreement and disagreement. 4教学过程Teaching procedures:Step 1. Leading-inPurpose: To activate Ss and arouse them to talk about global warming.T: Hello, everyone. Today we are going to read about global warming. But first let’ s think about what moves the world around .Yes, it is energy. But what is energy?Energy is a fundamental quantity that every physical system possesses; it allows us to predict how much work the system could be made to do, or how much heat it can produce or absorb .In the past, energy was discussed in terms of easily observable effects it has on the properties of objects or changes in state of various systems. Basically, if something changes, some sort of energy was involved in that change. Renewable energy sources like wind power don’t emit carbon dioxide.Step 2 Warming upPurpose: To lead Ss to the topic of this unit.Pair workGet Ss to ask each other the following questions, and then ask them to present it before the class.(1) What is energy?(2) Where does it come from?(3) What energy sources are renewable?(4) What energy sources are non-renewable?2. Group work(1) Get Ss to talk about sources of energy according to the following photos.The above pictures can be used for Ss to talk about, and Ss can also talk as much as they can.By learning Warming Up we all know that energy is so important, but where does it come from?There are different forms of energy:Light energy 光能 Heat energy 热能Sound energy 声能 Chemical energy source 化学能源Nuclear energy 核能 Internal energy 内能Kinetic energy 动能 Potential energy 势能能源类型定义实例一次能源直接来自自然界而未经加化石燃料、太阳能、核能、生工转换的能源物燃料、水能等二次能源由一次能源直接或间接转化而来的能源电能、煤气、汽油、沼气、氢能等可再生能源不随其本身的转化或被人类利用而减少的能源太阳能、生物能、水能、风能、地热能等非再生能源随其本身的转化或被人类利用而减少的能源化石燃料、核燃料(2) ConclusionWhen energy changes from one form to another, the amount of energy stays the same. Energy cannot be made or destroyed. This fact is called “conservation of energy”. Matter can be made into energy through processes like nuclear fission and nuclear fusion.3. Competition:Take the quiz below and see whether Ss can fill in the blanks.

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. N ext 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.

英语：Unit 4 《Global Warming 》教案-reading （新人教版选修6）Period 2 Pre-reading, Reading, ComprehendingTeaching Goals:1.To read about global warming.2.To get some idea about the effect of global warming.3.To develop some basic reading skills.Teaching Procedures:Step 1. Warming UpPurpose: To arouse Ss interest in learning about global warming.1. Team workAnswer the questions below:(1) Have you ever seen a greenhouse?(2) How does a greenhouse work?(3) What do you think greenhouse gases do?2. Group workLook at the picture, and ask Ss some questions.T: What is this building made of?S1: It’s made of plastic.T: What’s its purpose?S2: Plants can grow in it when it’s cold outside.T: How does it work?S3: The glass traps the heat from the sun, making the air warm so that plants grow better.Step 2. Pre-readingPurpose: To get Ss to learn about greenhouse gases.1. Group workNow look at the word “GREENHOUSE GASES”. What does it mean?Greenhouse gases (GHG) are gaseous components of the atmosphere thatcontribute to the greenhouse effect .The major natural greenhouse gases are watervapor, which causes about 36-70% of the greenhouse effect on Earth (not includingclouds): carbon dioxide, which causes between 9-26%; and ozone, whichcausesbetween 3-7%(note that it is not really possible to assert that such-and-such a gas causes a certain percentage of the GHE, because the influences of the various gases are not additive .The higher ends of the ranges quoted 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 most of these naturally occurring gases.Very powerful greenhouse gases that are not naturally occurring include hydrofluorocarbons(HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are generated 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 the answers.(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 naturalphenomenon.(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 asmuch 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.
