高二英语选修6教案Unit4GlobalwarmingPeriod1含解析
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。

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。

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。

Teaching difficult points 教学难点Enable the students to learn how to express agreement and disagreement.教学过程Step ⅠRevisionT: Good morning, everyone.Ss: Good morning, teacher.T: Sit down, please. 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 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?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 ⅢListening and DiscussingT: From what 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: And meanwhile it pollutes the environment.T: It’s true. Many people have realized the problem. Next we’ll do some listening practice on this topic. Let’s see what other people think of this issue.The students are asked to read the questions quickly to find out the listening points first. Then listen to the tape twice and give the correct answers.T: Now please turn to page 31. Let’s do listening. Before you listen to the tape,please read fast the statements in Exercise 1 to find out the listening points.Pay much attention to the key points while listening.Play the tape for the first time. Help the students get a general understanding about the dialogue. The students listen and try to finish Exercise 1. Play the tape again, train the students’ability to spot specific information and under standthe implication in the dialogue. The students listen and finish Exercise 2.Several minutes later.T：Have you finished the exercises?Ss: Yes.T: OK,let’s check your answers.Explain some difficult points if necessary.T: Now read what Professor Chen and Li Bin say. Work in groups. Discuss who you agree with and give reasons. Use some of the phrases listed in Exercise 2 or any others you know.课后小结学完了这节课，你有什么收获？课后习题1.Try to find some other useful ways to help smokers quit smoking on the Internet.2.Read the passage again and find out the important words and structures.板书Unit 4Global warming。
