Unit 5 The power of nature Ⅰ. 单元教学目标Ⅱ. 目标语言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，理解到自然的伟大力量，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，提升自我保护意识。

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，为随后实行的听、说、读、写打下基础。

1.2 Pre-reading通过回答问题测试自己是否适合作火山学家，让学生了解这个陌生职业，为阅读做好准备。

1.3 Reading部分一位火山学家以第一人称的形式讲述了自己的工作及第一次目睹火山爆发时的情景和心情，描写了人与自然的斗争与和谐相处的乐趣，使学生理解到火山是美丽的，但同时极具破坏力，而火山学家的工作能够减少由火山引发的损失。

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。

1.6 Using Language以语言实践为目的，包括四个部分的内容。

Listening and speaking 三位火山学家讲述了他们各自最惊险的一次经历。

学生在练习听力的同时学会描述害怕和紧张的词汇。

Speaking 是Listening的延续。

Reading 介绍了旅游胜地The Lake of Heaven, 培养学生快速获取信息的水平。

【语法讲解】英语Unit 5 The power of nature现在分词的用法补遗1. 现在分词的完成式一般只用作状语，不作定语。

如：The temple which has been destroyed by the earthquake will be rebuilt soon. 被地震毁坏的庙宇很快就要重建了。

误：The temple having been destroyed by the earthquake will be rebuilt soon.2. 如果现在分词表示的动作不是其逻辑主语发出的，该分词要用被动式。

现在分词的一般被动式表示一个被动的动作正在发生（如例①）；现在分词的完成被动式强调该分词表示的动作发生在谓语动词所表示的动作之前（如例②）。

如：①The problem being discussed is very important. 正在被讨论的问题很重要。

（指正在发生的被动动作）②Having been told many times, the naughty boy made the same mistake. 被告诉了好几遍，这个淘气的孩子还是犯了同一个错误。

（Having been told先于made发生）误：Being told many times, the naughty boy made the same mistake.3. 现在分词的否定式应在其前面加not。

如：①Not having been invited to the party, she was very upset. 没有被邀请去参加晚会，她很恼火。

误：Having not been invited to the party, she was very upset.②Not seeing my brother, I asked my mother where he was. 由于没有见到我弟弟，我便问妈妈他在哪里。
