Unit 1 课时3 Section A Grammar Focus（教学课件）英语新教材五四鲁教版九年级全一册

该初中英语课件聚焦被动语态，系统讲解基本句型、不同时态及情态动词结构和使用场景。课堂导入通过主动与被动语态对比，类比中文“把字句vs被字句”，搭建从已知到未知的学习支架，帮助学生理解语法逻辑。 其亮点在于融合语言能力与文化意识，如Practice环节以青藏铁路语篇为载体，在语法练习中渗透中国工程成就。任务设计从识别、转换到语篇应用，提升学生语言表达与思维品质。Homework的创新任务促进知识迁移，助力教师高效教学，学生提升综合语言运用能力。

Unit 1 Power of Ideas 主讲人：XXX 课型：听说课 Section A Grammar Focus 能够识别被动语态的句子结构，区分不同时态被动语态的形式特征，读懂例句与青藏铁路语篇，提取被动语态的使用场景、动作执行者、时间背景等关键信息，理解被动语态在介绍发明、工程类话题中的表意作用。（学习理解） 01 能够准确圈出句子里的被动语态动词，根据时态提示用动词正确被动形式完成单句填空、青藏铁路短文填空练习，规范书写被动语态句子，能用被动语态复述青藏铁路建设的相关难点与解决办法。（应用实践） 02 能够借助被动语态自主撰写一段介绍我国重大工程或生活创新发明的简短介绍，向同伴口头讲解项目亮点，感悟工程创新背后的智慧与社会价值。（迁移创新） 03 学习目标 Lead in 01 Presentation 02 Practice 03 Summary 04 Language points 05 Exercises 06 Homework 07 Contents Lead in 01 Active Voice vs. Passive Voice Presentation 02 主动： 被动： Peter cleaned the bedroom. 动作执行者 动作接受者 The bedroom was cleaned by Peter. 动作接受者 动作执行者 or The bedroom was cleaned by Peter. 句子的重点在于房间被清理，动作执行者是谁并不重要的情况下，可以直接省略不提。 Active Voice vs. Passive Voice ≈把字句 vs. 被字句 Peter打扫了房间。/Peter把房间打扫了。 房间被Peter打扫了。 被动语态的基本句型 主语+be+过去分词+（by执行动作者） （接受动作者） 被动语态的基本元素就是：be+过去分词。 无论是什么时态的被动语态，这两个元素都缺一不可。be则随主语及时态做变化。 一般现在时： I watch TV every day. TV is watched by me every day. 一般现在时被动语态：am/is/are done 一般过去时： I watered flowers last night. Flowers were watered by me last night. 一般过去时被动语态: was/were done 被动语态的基本句型 情态动词： We can finish the task today. The task can be finished by us today. 情态动词被动语态：modal v. +be+done 被动语态的基本句型 被动语态的使用场景 1 想要凸显动作的接受者时 Jack has been fired. 强调被开除的人是杰克。 2 动作执行者不重要时 The meeting is cancelled. 重点是会议被取消，至于被谁取消，并不是那么重要。 被动语态的使用场景 3 动作执行者众所皆知时 English is spoken in this area. 说英语的一定是“人”，故不需特别强调。 4 不知道动作执行者是谁时 My wallet was stolen. 只知道钱包被偷，却不知道是被谁偷了。 5 希望让语气较为客气时，被动语态的口气会比主动语态委婉 主动语态：We rejected your request. 被动语态：Your request has been rejected. 被动语态使得“拒绝”这个动作显得比较不那么直接。 主动与被动的转换 主动句：Mom watered the garden. 被动句：The garden was watered by Mom. 1 2 3 将主动句中的宾语改为主语 动词改为被动语态 将主动句中的主语，放在介词by之后，并接在被动语态后 Practice 03 4a Read the sentences.
