Material analysis本课是第二单元第三话题的第三课时。主活动是1a。1a 介绍了世界各地的人们如何开发和利用环境友好型和资源节约型的新能源，同时也指出了这些新能源的利用方式所存在的不足之处。在介绍的过程中，让学生学到更多并列句的连接词。如：however, not onlybut also等。1b通过图片匹配可以帮助学生形象地理解比较陌生的事物。1c培养学生归纳处理信息的能力。2a和2b 是两个关联性很强的任务。2a指出人们可以利用可再生能源来发电，并让学生讨论怎样利用这些可再生能源，然后在2b环节形成书面报告。这两个环节，其实是培养学生学会作记录，并根据记录整理成短文的能力。2b是个书面活动，可以留作家庭作业。.Teaching aims1.Knowledge aims： 掌握本课的重点词汇和短语，继续学习并列句。2.Skill aims: 学会更多连接并列句的方法。学会在讨论中作记录，并整理记录使之成文。能够对信息进行分类处理。3.Emotional aims: (optional) 激发学生探索利用新能源的热情。4.Culture awareness: (optional) 了解世界各国在开发和利用新能源方面的现状和成就。.

But it requires long time to produce biogas and it costs much to build them. Electric vehicles can not only protect the environment but also save energy. But its too small to hold many people. Maglev trains run very fast and quietly. They are energy-efficient and they have no pollution. However, the paths are much more expensive than the traditional steel railways.让学生单独复述课文有一定的难度，最好是老师带着一起复述。.
