教学设计
Step 1 Lead-in(2mins)
通过欣赏影片, 引入这节课,激发学生的学习兴趣,从而引出主题(化石燃料的燃烧)。
(设计意图:此步骤从视觉、听觉、感觉的角度设计英语课堂教学结构,使学生的学习与感受融于一体,引起学生对主题的思考与关注。)
Step 2 Pre-reading (1mins)
以下为听力短文中可能遇到的生词:fossil fuels,industrial society,energy, concentrate,radiation,nuclear power,etc.让学生说出意思,并且领读两遍。
(设计意图:该活动能让学生快速进入课堂学习的状态,开始思考学习的主题,激发学生联想与主题相关的信息,开拓学生的思路。学生会联想到一些相关词汇;还会让学生认识到减少空气中二氧化碳的重要性,从而引入到话题what shall we do in our daily life ?)
Step 3 Listening (20mins)
The listening text is a radio interview about the use of fossil fuels and other sources of energy. It contains two parts and examples of the focus function for this unit:agreeing and disagreeing.

3. We can replace fossil fuels with cleaner sources of energy. ( )
4. Nuclear power is a good source of energy. ( )
教师活动:让学生快速浏览题目,猜测教授会否定哪些观点。
学生活动:快速浏览,对对话内容有所了解。
(设计意图:读前活动让学生大致了解听力内容,激发学生的背景知识,引发学生对此话题进行思考。采用泛听的方法,不必听懂文中的每一个单词和句子,为随后的听力活动做准备。)

Task 3. Listen for the key words(7mins)
Play Part 2 for students. And ask them to recall the missing information. Then play the tape right through while students listen for the missing details. Play it twice if necessary and then check answers by playing the tape again and stopping when the missing details are given.

community. That means and countries will have to work together.

(设计意图:本部分是听力训练的重点,以精听的方式为主。学生听完后马上回答相关问题和填空活动,因此,他们要带着目的去听,寻求所需要的信息。此步骤考查的是学生对听力材料细节的把握,学生需要针对所听的内容进行信息加工。)

课后反思
1. 由于本堂课任务多,容量大,导致“快节奏”,应给学生以更多时间准备,今后应注意教学步骤间的过渡和衔接,从而使学生的语言技能得到充分锻炼,体现教师主导、学生主体作用。如:让学生读对话并回答问题。
2. 辩论题设置较好,但难度较大, 应与讲授知识点融合在一起,这一环节节省导致很多学生没能积极发言。今后应多引导, 更多的时间就可用来锻炼学生的语言技能。降低难度,留足讨论时间,鼓励学生大胆开口。
评测练习
Write a poster(海报)about this topic. Make a poster for your school that tells students various ways they can reduce the amount of carbon dioxide in the air.
Sample poster Fight global warming Cut down on energy. Cut down on carbon dioxide. If not using an electrical item, turn it off. If you suddenly feel cold, don’t turn the heat up, put on a jacket instead. Walk or ride a bike and save fossil fuels. Recycle paper, cardboard and newspapers. Buy products made from recycled materials. Buy energy – saving products like low energy light bulbs. Plant trees to absorb CO2. Tell your friends about global warming. Every effort counts!
