人教版（2019）选择性必修第四册 Unit 1 Science Fiction Period 2 Discover Useful Structures 被动语态复习 导学案 学情分析 学生在前面几个单元已经接触过被动语态的基本形式（一般现在/过去时被动、将来时被动、现在完成时被动），也在课文里见过进行时被动和非谓语的被动形式，但考到不同时态混合填空时容易混，尤其是情态动词后面接被动形式时学生最容易漏写 be。这节课紧扣单元科幻主题，以武汉城市发展与光谷科技未来为情境来讲，先梳理形式再练语境，降低复习的枯燥感。 学习目标 1. 能通过观察例句，归纳被动语态的各种形式（各时态、情态动词、非谓语动词）。 2. 能在描述武汉城市建设、光谷科技与未来生活的语境中正确使用被动语态。 3. 能判断什么时候该用被动语态、什么时候该用主动语态，体会被动语态的语用功能。 学习重难点 重点：各时态被动语态（一般现在/过去/将来、现在完成、现在进行）及情态动词被动的结构与基本用法。 难点：① 现在进行时被动语态（is/are being done）的结构；② 主动语态与被动语态的语用选择（写作中何时用被动）。 课堂探究 Part Ⅰ Lead-in Look at the scenes of Wuhan and fill in each blank with the correct form of the word in brackets. 1.
