Unit 3 Inventors and inventionsⅢ. 教材分析和教材重组1. 教材分析本单元以Inventors and inventions为话题，旨在通过单元教学，使学生了解发明和发现的区别，了解发明创造的过程和获得专利的条件，学习发明家的成功事例；能灵活运用基础句型描述中外古代和现代发明，谈论不同发明的优缺点及其现实意义；根据不同问题及条件设计、改进发明并阐述自己的观点；能写一封有创新的求职申请，阐述自己的特长和优势，能对别人的发明、创造或观点提出意见或建议；并能运用所学知识利用现实生活中有限材料进行发明创造。

1.2 Pre-reading要求学生将课本所列关于进行科学研究或发明创造所必须经历的几个阶段（步骤或过程）进行正确的排序。

了解每一项发明在得到社会承认前都必须经历一个过程。

1.3 Reading是一篇记叙性的文章。

(一). 分词的作用：1、作定语（1）单个分词作定语，分词前置。

如：The sleeping boy is my son.The excited people rushed into the building.A lost opportunity never returns.He is a retired worker.（2）分词短语作定语，分词后置；分词修饰不定代词something等要后置；个别分词如give，left等作定语也后置。

如：The girl standing under the tree is my niece.The building built last year is our library.This is the question given.There is nothing interesting.（3）过去分词作定语与其修饰的词是被动关系，相当于一个被动语态的定语从句。

如：Most of the people invited to the party were famous scientists2、作表语如今分词作表语多表示主语具有的特征，过去分词作表语多指主语所处的状态。

如：The film is touching.The glass is broken.She looked tired with cooking.He remained standing beside the table.3、作宾语补足语分词和不定式一样，在一些感官动词或使役动词后作宾语补足语。
