初中九年级英语全册 Unit 6 When was it invented？第3课时备课教案
Unit 6 When was it invented？（第3课时）【学习目标】1.知识和技能目标：1）谈论重要发明的发明时间，发明者和用途。
2) 了解薯条、茶和篮球的发明历史。
2.过程与方法目标：1）能运用所学知识练习被动语态的句式。
2）能用所学句型进行交际练习。
3.情感、态度和价值观目标：充满想象力，善于观察事物，面对难题，用积极的态度解决，发挥创造能力，认识世界，改变世界。
【自主梳理】1. 要求学生翻开课本P45，迅速阅读1a-1e部分的内容。
并按要求完成课本上相应的任务.2. 检查答案，先要求全班一起给出答案并检查讨论。
【重点领悟】通过谈论薯条的发明，充分掌握被动语态的用法.【探究提升】初中被动语态语法讲解(一) 语态分类英语动词有两种语态.，主动语态和被动语态。
主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
如：They will build a new bridge over the river. (主动)A new bridge will be built over the river. (被动)汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用：助动词be + 及物动词的过去分词构成。
(二) 被动语态的时态、人称和数的变化主要体现在be的变化上，其形式与系动词be的变化形式完全一样。
一般现在时：am / is / are + done一般过去时：was / were + done一般将来时：shall / will + be done一般过去将来时：should / would + be done现在进行时：am / is / are + being + done过去进行时：was / were + being + done现在完成时：have / has + been + done过去完成时：had + been + done将来完成时：shall / will + have been + done过去将来完成时：should / would + have been + done［注］被动语态没有将来进行时和过去将来进行时。
