1、教学内容九年级英语Unit6 When was it invented？Section A 1a1c课时Period1 教学对象九年级设计者邓琳一、教材内容分析本节课是第一课时，主要谈论四项发明的时间，让学生在听说活动中理解一般过去时的被动语态的用法，以及与一般现在时态的被动语态的区别。活动1a-1c是整个Section A的基础。活动1c要求学生使用I think it was invented before/ after的句型讨论图中发明出现的先后顺序。活动1b要求学生通过听力活动验证自己的预测，并将以上发明与其时间匹配。听力材料中输入了本单元的重要语言结构：When was it inv

2、ented? It was invented in活动1c则要求学生结伴，用前面的语言结构谈论这四项发明。1a1c没有生词，只谈四项发明的时间，且与2a的谈物品用途联系不大，因此我对本节课的重点句型重新进行了划分，将What is it used for? It is used forWhen was it invented? It was invented in两组句型以及对应的复数形式呈现在了本节课，使学生在本节课有话题可谈的同时，也分解了单元目标的重难点。二、教学目标（一）知识目标：1、熟练掌握年份的读法。2、熟练掌握并运用下列句型的单复数形式：I think the TV was in
