教学反思：

本节课属于高年级的阅读课，话题围绕保护地球环境展开，培养学生热爱地球、保护地球的意识，了解更多保护地球的方法。本节课中，我借助问题，围绕核心词Why?和How？，创设多样的教学活动，引导学生思考，在交流中促进学生思维和表达能力的发展。

1.传授技能，提升学生的阅读能力

阅读课的教学不同于一般对话和故事教学，需要给学生一些阅读技巧。在本节课中，我让学生通过学习阅读策略解决相关问题，如借助思维导图的方式帮助学生梳理文章的脉络。在教学过程中，我自然渗透指导学生如何制作思维导图，如可以用一些图片代替表达内容等等。我还指导学生学习一些阅读策略，如提炼文章主旨——四种保护地球方式，提炼关键词Why?和How？，以及根据图片和上下文猜测新单词reuse和cut down的意思等。学生只有学会了这些阅读策略才能提高阅读能力，才会在阅读中提高综合能力。

2.层层推进，培养学生的思维能力

本节课的教学设计是思维导图的的建构过程，我在不同阶段采用不同的阅读方式，提出不同的问题与任务，引导学生主动、积极地思考。仔细分析教材，发现语篇中四种保护地球的方式都是是围绕Why?和How？展开。于是我层层推进，设计有梯度的任务，分段学习语篇。在学习每个语段时，我都紧扣话题和段落小标题， 在学习Save energy时，我为学生在理解和表达上提供了支架，引导学生先思考“我们为什么要这么做？”，然后思考“我们应该怎么做？”，通过呈现思维导图，呈现文章的脉络信息，使学生理解得更加清楚，表达的更加流畅；在学习Don’t use too much plastic时，我示范了如何在语篇中寻找关键信息“我们为什么要这么做？”完成思维导图后，就让学生完成另一半“我们应该怎么做？”的思维导图；到最后相对比较简单的Save water和Save trees片断，就完全放手让学生自己阅读尝试制作思维导图了。随着段落的层层推进，语篇的主题更加凸显，学生保护地球的情感与意识也越来越强烈。学生围绕主题“Protect the Earth”，在思维导图的帮助下，构建了自己的知识网架，提升思维逻辑能力，也更加深刻的理解了语篇。

3.及时反馈，提高课堂学习效率

最后巩固环节，我利用了书后“How to protect the Earth?”的缺词填空，并把它设计成“倡议书”，不仅当堂考验了学生语言知识的掌握情况，我还将学习内容延伸到了课外，拓展了We  should  turn off  the light when we go out.以及We should protect animals.，让学生传递保护地球，从身边小事做起的环保理念。
