ReadingPre-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 exercises⑴ What is the building made of and what its purpose?⑵What’s greenhouse effect?Teaching aims:1.To read the text “The earth is becoming warmer—but does it matter”and understand what it says.2.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:1.A debate over whether it is human activity that has caused the globalwarming or whether it is just a natural phenomenon.2.Many scientists be lieve people have caused the increase in the earth’stemperature.3.The increased extra amount of carbon dioxide traps more heat energycausing the global temperature to go up.4.The levels of carbon dioxide have increased greatly over the last 100to 150 years.5.There are some different attitudes towards the causes of this increasein carbon dioxide.6.Over the next 100 years the amount of warming could be as low as 1to 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 environmentalconsequences.10.M ore carbon dioxide is a positive thing.11.N o one knows what the effects of global warming will be.Step 3.

Unit_4_Global_warming教案
Unit 4 Global warming1. 教材分析本单元以Global warming 为主线，旨在通过单元教学使学生经过思考、学习，认识到全球变暖的起因和它所带来的种种后果。
同时鼓励学生进一步阐述地球所面临的其它严重问题，激发学生的环保意识。
引导学生运用所学语言、句式表达自己对这些现象的看法，培养他们为自己的观点辩论的能力，并能运用所学知识写一篇有关环境问题的论文。
1.1 Warming Up通过直观的图片，使学生对能源的用途和种类有一个基本的了解。
让学生对当今人们开发和使用能源以及随之而来的种种影响有更深一步的思考和认识，从而为本单元主题Global warming 作了很好的铺垫。
1.2 Pre-reading是Reading的热身活动。
通过组织学生对这些问题的讨论、回答，激活他们头脑中相关的内容模式，为下一步阅读做好准备。
由于Global warming 是当今世界的一个热门话题，学生已从多种渠道对此有了很多的了解，因此教师可以在安排预习作业时让学生分组做 a project on global warming , 这样既符合了新课程的要求——体现学生的主体地位，激发学生自主学习的热情，又能得到很好的教学效果。
1.3 Reading是一篇从杂志节选的文章。
它讲述了全球加速变暖的原因——人为温室效应，后果以及人们对此的不同观点。
要求学生在理解文章大意的同时注意它的写作技巧：提出问题——分析现象——阐述各方面的不同观点——以疑问句作为总结引发读者深思，自行做出判断。
这为Comprehending 中Exercise 3的分组辩论活动留出了很大的空间，埋下了很好的伏笔。
1.4 Comprehending 包含了三大部分。
前两个部分中设计了诸多细节性的问题，旨在检测学生定位、理解细节及对文章大意的总结归纳的能力。
最后一项要求学生在读完整篇文章后，仔细思考并树立自己的观点：“We should do nothing about global warming”还是“We should do something to decrease the speed of global warming”，并利用所学知识进行分组辩论。

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。

To develop students’ sense of cooperative ability;
Teaching important points : To enable students to learn about global warming and to develop their reading ability.
Teaching difficult points: To enable students to talk about what we should do to prevent global warming.
Teaching aids: Multimedia
Teaching procedures:
Step1 Warming up
Talk about weather and lead the relationship between severe cold weather and global warming. Then play a video and ask students to think about what the video shows so as to lead today’s
^
topic-global warming.
Step2 Talking
Play a second video and the students are supposed to talk about what is happening in the video. Then the teacher comes to a conclusion:The animals’habitats are destroyed. That means animals will die out one day.
Step3 pre-reading
Ask students questions:What is a greenhouse made of and used for Have you ever seen a green house
A greenhouse is made of ______ and is used for ______________,especially during
_____weather.
Step4 group work
Ask students to work in groups to discuss how does a greenhouse work
The answer:The glass traps the heat from the sun and keeps it from escaping. So the air inside is warm. This makes the greenhouse heat up and so the plants can grow throughout the cold period.
Step5 reading
•|
•Ask students to skim the passage quickly and answer the following questions:What are the “greenhouse gases”
•Who talked about “greenhouse effect”
•What is greenhouse effect
•And then check the answers. And then ask them to read it again and work in pairs to answer :Can we live without greenhouse effect
•Who wrote the article
•What’s the name of the magazine
•What are the names of the three scientists mentioned in the article
•What did Charles Keeling find And do you agree with her
•Does George Hambley agree with Dr Janice Foster

！
Step5 detailed reading
The teacher tells that the test can be divided into 4 parts so show them a diagram and ask them to match which part with the right main idea.
Step6 An activity—Make a poster
Saving energy means reducing carbon dioxide, which is our duty.
What should we do to slow down global warming
Make a poster for our school that tells students various ways they can reduce the amount of carbon dioxide in the air.
Step7 Homework
•Composition:
•以“how to slow down global warming”为题写一篇发言稿。
