教材分析

本单元的话题是“植物和植物采集的历史”，通过单元学习，学生将了解一

些植物学的常识、18和19世纪西方植物采集的历史、一些奇异的植物及授粉知识。学生在听、说、读、写等技能训练的基础上，将了解植物对人类的重要意义和植物学家对不同植物种类在全世界的传播所做的贡献，从而培养对植物的兴趣，并能树立爱护植物、保护热带雨林的良好意识。

1.1

Warming

up

是本单元的热身活动，列出了几个有关植物的问题，要求学

生回答这些问题，然后小组交流，分享对问题中提到的植物的了解，并能说出一些特殊的植物，从而引发学生对植物这一领域的兴趣。

1.2

Pre-reading

是阅读的热身，要求学生结合自己的生活实际回答几个问题，

并激发他们了解更多有关植物知识的欲望，例如“植物是如何从一个地方漂流越洋到另一个地方？”等。另外，还要求学生根据文章标题和插图预测文章的内容，为后面的阅读做了充分的铺垫。

1.3

Reading是一篇有关十八、十九世纪植物学研究和探索的文章。该文章介

绍了植物收集历史的起源，并介绍了西方历史上几位著名的植物学家以及他们对植物学研究所做的贡献。

1.4

Comprehending

设计了四个活动，检验学生对课文内容理解：1要求学生

分析各段落大意，并用自己的语言写出每段的主题；2列出了一些日期，要求学生运用找读技巧找出每个日期所发生的历史事件；3要求学生分组讨论一些问题，检验他们对文章一些细节的理解；4是一个小组活动，要求学生四人一组进行角色扮演，其中一个是船长，其他三个是植物学家，三个植物学家将分别向船长介绍他们各自选择的植物的种种好处，说服船长把他的植物带回本国去。该活动是对文章内容的一个拓展，训练学生应用知识的能力和口语表达能力。
