1、Unit 1 Great scientist 第一部分About the topic and the structures单元话题和结构本单元的话题是“伟大的科学家” ，介绍了西方历史上的两位科学家。本单元句法项目是“过去分词作定语和表语” 。题解：科学家是专门从事科学研究的人士，包括自然科学家和社会科学家这两大类，凡可以称之为科学家的都是一些成功人士，如：牛顿、哥白尼等。教学设计在单元课时划分上与课本保持一致，即“阅读课、知识课、运用课三课时/三课型划分” 。但在实际教学过程中，我们建议教师依据学生基础、教学条件、学校安排的因素，对课本、对教学设计重新划分课时、裁剪、拼接使用我们提供的材料，
