　　ⅲ. 教材分析与教材重组
　　1. 教材分析
　　本单元以the power of nature 为话题，旨在通过单元教学使学生了解火山爆发、地震、台风、洪水等自然现象，认识到自然的伟大力量，并会用所学词汇描述在经历自然灾害时的感受，思考人类应对自然灾害的态度和方法，提高自我保护意识。
　　1.1 warming up通过对火山爆发示意图的讨论激活学生了解与本单元话题相关的背景知识，而后通过讨论人类应对自然灾害的措施引发学生对本单元话题的思考，激发学生的求知欲，为随后进行的听、说、读、写打下基础。

　　1.4 comprehending设计了两种题型：第一题要求学生在阅读后回答相关问题；第二题检测学生对文章细节的理解。
　　1.5 learning about language 分为词汇和语法两部分。词汇部分着重从词的意义用法和表达方面对学生学习词汇给予指导；语法部分学习ing 形式在句子中作状语表示时间、原因及结果。

　　1.7 summing up与learning tip有助于学生自我检测，便于及时复习。通过学习同根词、同
