2.While listening to the last part of the
1.Listen to the song and get the missing words of the lyrics. I need to move I need to change I need to shake up I need to speak out
听这首课前要求观看的记录片的主题曲并填词来导入新课，通过对此部分歌词提问从而分享他们结合记录片对歌词的理解，回顾
song, try to get the missing words of the lyrics.
2.Since this part is repeated 4 times in the song, ask Ss the deeper meaning of the song after watching the documentary. Q1: What does something refer to ? Q2: What does the whole sentence Something’s got to break up mean? Q3：Why “Something’s got to break up”?
Q4：What does “I have been asleep”mean?
So I need to move,I need to change„ But when? NOW!
3. But how to move, how to change, how to„? This is what we are going to discuss today. Something’s got to break up And I’ve been asleep And I need to wake up Now 2.Talk about the deeper meaning of
this part.
global warming的起因，影响，以及人们对此问题的态度。引出本课内容：What can we do about global warming?（这几个问题回答了global warming带来的影响，原因及人们对此的认识，现在觉醒起来且刻不容缓）
Step 2: Reading
(But when it comes to such huge environmental problems, people may think it’s governments and businesses that have the responsibility to act. Individuals are powerless to do anything.)
1.Fast reading for Letter 1. Find out Ouyangguang’s opinion to global warming and his purpose of writing this letter.
(Does Earth Care agree with his opinion?)
2.Skimming for Earth Care’s opinion. 3.Scanning for Earth Care’s suggestions and summarize them to fill in the blanks. 1.Skimming, scanning for information needed. 2.Fill in the blanks about the suggestions.
通过阅读这两封信来
了解建议信的特征，并通skimming, scanning来获取信息，提高快速获取信息能力。通过填词训练来考查其归纳能力。
Step 3: Discussion
Besides these suggestions. What other suggestions can you give on
energy-saving and emissions reduction? 1.Group discussion for more about what
Group work: Discuss for more suggestions to fight against global warming.
1.4 groups discuss how to save
通过小组讨论从衣、食、住、行四个方面来寻求更多的节能减排方法。然后通过抢答的方式看看哪个组列举we can do? In order not to repeat others’, you can list your suggestions on different aspects:
clothing(Group1) Food(Group 2) Housing(Group 3) Transportation (Group 4) 2. Have a competition to see which group can give the most. energy on 4 basic necessities of life. 2.Have a competition.( 1point for one suggestion.)
的最多。一条建议一分。此环节可调动学生
参与的积极性。
Step 4: Pictures & Free talk
(You have collected so many practical suggestions. But sometimes it’s easier said than done! Why do I say so?) 1.Show some pictures for them to see what is really happening in our daily life. I think you must have something to say. (To learn about the knowledge of global warming is important. To learn how to cut down on usage of energy and reduce the carbon emissions is important. But the most important is to turn the knowledge into action, to change some familiar patterns or habits, to do what we can do and to influence people around us.) But how?
2. List some ways to be an educator. （As a student, maybe making posters is an easy but efficient way to make our voice heard.）
1. Think what are doing to the environment from these pictures and have a free talk about it. 2.Think of more ways to be an educator. Giving speeches
Organizing some activities Making films
Taking with family or friends Making posters ……. 通过这些生活中的图片展示，让学生们意识到人人都是造成global warming的一份子，节能减排，人人有责，且刻不容缓。并且通过怎样用自身去影响别人过渡到本课的写作要求---制作海报上。
Step 5:Presentation
1.Ask each group to present their poster and report it in proper language.
2.Show a poster model to see what elements are necessary to a poster.
3.Ask Ss to give a proper mark to each poster to see which one is the best.
Each group presents their poster and reports it in proper language to the whole class.
Give a proper mark to each poster. (1-5 points)
根据课前导学中微课
关于海报的类型与制作，每组一个代表来完成本组海报展示，宣传节能减排。并结合海报要素来给每组海报评分。
Step 6; Summery (Since we have discussed and collected so many suggestions, I think you must get the answer to Think about what we have learnt today and what we can do to protect the environment. Try to turn the knowledge into action
总结：
通过今天的讨论，回答了最开始提出的问题：
How to move, how to
the question raised at the beginning of the class---How to move, how to change, how to speak out…. Right?)
Please remember: Each one of us is a cause of global warming, but each of us can make choices to change that, with the things we buy, the electricity we use, the cars we drive. We can make choices to bring our individual carbon emissions to zero. The solutions are in our hands. We just have to have the determination to make them happen. I believe, we believe, THE CLIMATE CRISIS CAN BE SOLVED!)
in our life.
change, how to speak out…. （利用歌词做到首尾款呼应） 告诉学生：记住虽每个人都是造成全球变暖的一份子，但我们可以通过我们买的东西，用的电，开的车等等做出选择去改变，甚至将个人二氧化碳排放降低到零。解决方法就在自己手中，我们只要有信心让这些发生，相信：全球气候危机是可以解决的！
Step 7 Bullet screen
