【课标分析】
在必修课程完成的基础上引导学生学习选修课程的部分内容，为学生提供多样化选择的余地和发展个性的空间，从而激发学生用英语探索世界的兴趣，拓宽英语学习的渠道。扩大学生的知识面，从而在一定程度上实现跨学科教学，为学生感悟人生、规划人生提供绝佳实践机会。秉承这一宗旨并结合十八大以来“绿水青山就是金山银山”、构建“资源节约型社会”的绿色环保理念，围绕选修六教材第四单元Workbook中的Reading 部分进行讲解和拓展，帮助学生形成环保理念和绿色生活方式。
【教材分析】
教学内容源于选修六课本第四单元Workbook中的Reading 部分“Clean Up Your Butts and Bags”。本文结构清晰，主旨明了，但由于有些句子和短语难度较高，而学生基础较差，英语学习兴趣不足，把重心只放在该材料上容易陷入以往枯燥阅读课的死循环，违背本节课提高学生英语学习兴趣的初衷。故用该材料作为开篇，后设情景剧表演、环保动画片赏析和学生手作展示，以让学生充分参与其中为目的，尽可能让学生在课堂上用英语、说英语，并归纳得出本节课中的重点--四个带“Re”前缀的动词，培养学生处理垃圾的正确方式。从教材出发并结合生活中垃圾乱扔、随意处置的现状，引发学生对垃圾处理问题和当下济南市实施垃圾分类的趋势的关注和思考，从而培养学生的环保责任意识。
【重难点分析】
重点：
1) 进一步提高学生的阅读技巧，从阅读材料中了解到两种常见有害垃圾的相关信息以及随地乱扔垃圾的危害和原因，抓住关键信息和主旨并且用自己的话说出来。
2) 了解”re”前缀动词的特点和英语单词的一定组成规律。
3) 拓宽学生保护环境，改变生活方式的思路和途径，帮助其形成资源节约、垃圾分类的责任意识。
难点：
1) 学生的听力一直是弱项，用观摩动画片却不提供字幕的方式训练学生的听力能力，形式新颖却帮助学生训练抓关键字眼和上下文推测的能力。
2) 训练学生如何用日常英语和肢体语言表达自己的观点和看法是本节课的一大难点，尤其对很多学生来说敢于张开嘴、不怕犯错误是至关重要的一步。
【学情分析】
迄今为止，高二学生已经掌握了一定的重点单词和短语，具备一定的阅读技能。但不可否认的是大部分学生基础较差，词汇量不足，有些学生听力和语言表达能力欠缺。遇到长句子或者长篇文章就本能跳过，不想研究；单词发音不标准甚至不会念，以至于产生畏难情绪害怕听力题，不敢张口用英语表达自己。这些都是英语学习兴趣缺失，自信心不足的表现。这不仅影响其参与课堂，获得成就感，更将阻碍课堂的进程和质量。但同时学生又有很强的集体荣誉感，动手能力较强。
因此，先布置预习阅读材料和手工制作的作业，让其通过自主学习扫清阅读障碍的同时能够充分发挥想象力和动手能力，无形之中提高对课堂教学的兴趣。在课堂中增加动画片、时事新闻身边事物、用所学句型描述自己的观点等环节降低学生的畏难情绪，感受英语的实用性。引导学生小组合作学习，将其表演和展示与小组集体荣誉挂钩，增强其参与课堂的积极性。
【教学目标】
1. 知识与能力
1) 了解文章的主旨、关键信息和结构；
2) 重难点单词和句型，尤其是有关环保的 “re”前缀动词；
3) 充分了解处理垃圾的方式方法，促进学生增强环境保护意识。
2. 过程与方法
1) 采用问题导向的方法引导学生讨论有害垃圾处理的正确方式，视频观摩、情景表演和手工展示等方式归纳总结。
2) 将全班分为几个学习小组，通过自主探究和小组写作共享的方式找到解决办法，有助于拓宽学生思路，锻炼英语口语。
3) 引导学生善于观察并总结关键信息，明白环保“行胜于言”的道理。
3. 情感、态度与价值观
学生通过动画观摩和阅读材料掌握垃圾乱扔的种种弊端，并通过变废为宝手工制作的展示提高对环保议题的重视。进一步增强学生对垃圾分类的宣传和保护环境的主人翁责任感。
【教学过程】
I. Lead-in
When I say“holiday”, or “Let’s take a holiday!” Do you feel excited? Is there a beautiful scene in your mind? Now let’s enjoy a short video about holiday. After watching, please tell me what is taking a holiday?
Transition: now please imagine---if rubbish is taking a holiday, it is beneficial or harmful to our life? Today we’ll learn a passage about two kinds of common harmful rubbish.
----Cigarette Butts and Plastic Bags.
II Fast-reading
How many paragraphs are there in this passage?
Now let’s do fast-reading and find the main idea of each paragraph.
(Pay more attention to the first and last sentence in each paragraph.)
Paragraph 1. Litter is a serious environmental problem.
Paragraph 2 Cigarette butts are small but are still bad for the environment.
Paragraph 3. Plastic bags are a danger to the environment.
Paragraph 4. The environment would be less polluted if we do something
to look after our planet.
III Careful-reading
Pair work: please focus on Para.2-3 and fill in the chart about 3 questions:
How many cigarette butts/ plastic bags are littered/used every year?
How long do cigarette butts/ plastic bags take to break down?
What about solutions?
Cigarette Butts
Plastic Bags
How many
How long
solution
--- Why we should put cigarette butts into dustbin?
--- Why we should recycle plastic bags?
Transition: As we all know, actions speak louder than words! I hope you can turn what you have learned in the passage into actions.
IV Post-reading
1. Group work: role-play and act out what shall we do. You can choose any items you need on your desks.
Situation1: in a supermarket
Situation2: in the classroom
Situation3: near our school
---Competition 1: Which group want to share your performance?
---Let’s review their vivid plays:
In face of plastic bags, what should you do? ---- Reduce
What can we use to replace them? ---- Eco-bags and lunch boxes.
What about smoking and cigarette butts? --- say no or Refuse.
(The moral education point: as a senior high school student, we should not smoke at all.)
Transition: there are so many other forms of harmful rubbish in our daily life, such as drugs/ medicine, LEDs and batteries. However, are these all the rubbish? Is it enough to just reduce or refuse? What about the other ones?
2. A short video about Peppa pig and her family. While watching, please think about two questions:
How does Peppa’s family deal with rubbish?--- Recycle
Why does Miss Rabbit take away their car? --- She loves recycling.
Transition: Actually recycling is around us! For example: the recycling bins, the recycling center and reused office desks in every classroom
--- Can we say we also love recycling?
--- Latest news: the general plan of waste sorting in Jinan is coming!
--- Call on every student to do recycling at school and home, meanwhile promote it among friends and families. Because everyone should love recycling!
V Discussion
Can you list other ways of recycling in your daily life? Yesterday I gave you a homework to try to reuse these waste. Now let’s recognize them first:
Please use these sentence patterns to introduce your ideas to your group mates.
At first, it was a/ from…
Then I cut off…/ put…into… / burn…/ pasted to(粘)…/ tied up(绑) … (with…)
Finally, I made a …
---Competition 2: who wants to show your handwork to compete for your group?
---Your creative handworks and ideas remind me of a sentence:
There is no difference between rubbish and resource. Rubbish is misplaced resource.
资源与垃圾之间没有根本界限。垃圾只是放错了地方的资源。
--- All of you have succeeded in turning waste into wealth using your imagination, that is to say before throwing them away, you Rethink and reuse them.
VI Conclusion
Green lifestyle/ Eco-life = Reduce + Refuse + Recycle + Rethink
Message from teacher: Rebuild your lifestyles. Return to our green planet!
VII Homework:

Para1. What reminds you of this idea?
Para2. How do you do with original wasted thing?
Para3. What do you make? And what do you use it for?

【效果分析】
本节课的目标是通过课上“听、说、读”以及课下作业“写”来帮助学生了解四个带“re”前缀的动词，形成垃圾分类、资源回收的习惯和责任意识，养成节约资源的绿色生活方式，同时借助选修教材拓宽学生的知识面和运用英语的能力，提高英语学习兴趣。
在教学设计上，既有传统的阅读训练巩固所掌握的阅读技巧，又通过情景剧表演、动画片观摩和手工展示来锻炼学生听与说的本领，帮助学生多维度、多方面体会英语学习的成就感。另外，每名学生都参与到资源回收再利用的环节当中，更有利于其深切体会到绿色生活并非难事。
小组合作探究。全班共分为6个学习小组，学生通过小组完成部分阅读任务，情景剧合作表演以及手工作品的介绍与展示。尤其是在情景剧表演中，学生能用到平时所掌握的句型或单词，并根据乱扔烟头得出 “中学生不应该吸烟”等积极向上的价值观导向，是令老师十分欣喜的。学生通过组内合作和组间竞争顺利完成课堂教学任务，在积极展现自我、提高自我探究能力的同时更懂得小组协作的重要性。
在手工作品展示环节，先让学生课下体会变废为宝的乐趣，课上再给出学生接触过的句型和短语，一步一步引导学生大胆张开嘴，不怕犯错而大胆表达自己的观点。学生在实际运用中记忆的效果远大于机械性地背诵。
仍存在的不足：
学生仍局限于段首句和段尾句归纳主旨，对于关键词和关键信息的把握还有待提高。
小组合作中有个别学生没有充分参与其中，害怕用英语表达自己，害怕犯错；有些学生的发音不标准，有待纠正。
仅仅考虑课堂效果，如何帮助学生真正形成环保的绿色生活方式，加深课堂效果并转换为实际行动并没有充分涉及。
最后结尾如果能设置环节进一步将学生的情绪升华提高，相信教育效果会更好。
【教学反思】
选修课教材的设置从一定程度上为学生提供多样化英语学习的选择和发展个性的空间，拓宽英语学习渠道并激发学习兴趣。秉承这一宗旨并结合十八大以来“绿水青山就是金山银山”、构建“资源节约型社会”的绿色环保理念，围绕选修六教材第四单元workbook中的Reading 部分进行讲解和拓展。
本节课亮点如下：
1. 教学内容源于教材又不拘泥于教材。课本教材“Clean Up Your Butts and Bags”结构清晰，主旨明了，但由于有些句子和短语难度较高，而学生基础较差，英语学习兴趣不足，把重心只放在该材料上容易陷入以往枯燥阅读课的死循环，违背本节课提高学生英语学习兴趣的初衷。故用该材料作为开篇，后设情景剧、动画赏析和手作展示，以让学生充分参与其中为目的，尽可能让学生在课堂上用英语、说英语。能从教材出发并结合生活中垃圾乱扔、随意处置的现状，引发学生对垃圾处理问题和当下济南市实施垃圾分类的趋势的关注和思考。
2. 做好课前准备和铺垫工作是本节课的重点之一。学生自主预习reading材料，查解生词并了解主旨；同时对六种可能成为垃圾的物品进行介绍，启发学生关注其材质特点并发挥想象力再创造再利用。可以说本节课的成功与学生丰富的想象力和较强的动手能力密不可分。
3. 小组合作的优势尽显。打破常规上课模式，将不同英语学习水平的学生平均分在每个小组，为基础较差学生创造语言环境，在较好学生的帮助下大胆表达自己的想法；同时让学生在小组合作的环境下产生思想的碰撞，相互启迪，情景剧的成功展现就是最好的说明。
4. 构思新颖。用四个带”re” 前缀的动词做线索牵引整堂课的发展，让学生明白”re” 前缀的作用的同时巧妙地引出正确处理垃圾的环保理念，可以说主题明确，思路清晰。帮助学生体会英语单词的构词方法，减轻其在日后英语学习尤其是单词背诵过程中的畏难心理。
可以说本节课环节紧凑，思路清晰，层层递进地展现了垃圾乱扔现状所造成的危害和正确分类处理垃圾带来的巨大好处，让学生在拓展知识面的过程中学习英语，在用英语说英语的过程中培养环保理念。当然回过头细细反思也存在很多有待改进值得提高的地方：
1. 教师作为课堂的引导者却说的太多，没有真正做到把课堂还给学生。如何通过问题设置和环节安排让学生都能有的说，都能体会到英语课堂的魅力，是我日后应该仔细思考的。
2. 教师对学生的评价用语略显匮乏，善于捕捉学生身上的闪光点，从不同方面给与学生鼓励是提高学生英语学习兴趣和自信心的一大要点。
3. 环节设置可以再加精炼，减少数量挖掘深度可以使得课堂更加从容，最后的提炼升华部分可以再花心思，以达到更高的教育效果。
