Unit 12 Life is full of the unexpected.
Section A 1a-2d 教学设计
内容分析
本课是人教版九年级第12单元的教学内容。本单元主要学习如何讲述过去发生的事情。能够理解过去完成时（past perfect tense)，能正确使用有when, before, as, by the time引导的时间状语从句表示过去发生的事情。话题是unexpected events,贴近学生生活实际，能引起学生的学习欲望。Section A部分的中心话题是讲述发生过的意想不到的事情。教学重点是让学生明白过去时态和过去完成时态的区别，并能运用这两种时态叙述过去发生的事情。
本课是一节听说课。学习内容围绕女孩Mary因为晚起导致上学迟到等一系列后果。本课是本单元的第一课时，在整个单元中起着话题导入的作用。内容贴近学生的生活实际，所含功能句都是日常生活用语，因此课堂任务应侧重培养叙述的语言实践能力。1a-1c用五福主题图片呈现了女孩Mary遭遇到的一系列意想不到的事件场景：睡过头、浴室被占用、跑步出门、错过校车和把书包落在家。活动围绕这五幅图片，以看图说话、听力及对话展开是整个Section A部分的基础。这部分还引入了新的语法结构：过去完成时。
学情分析
本节课的中心话题是围绕女孩Mary因为晚起导致一系列意想不到的事件。在讲述过程中，when, before, as, by the time引导的时间状语从句用一般过去时态，这个时态由于是复习，学生易于掌握。同时导入过去完成时，让学生了解过去完成时态描述过去某一时间或动作之前已经发生或完成的动作。这是重点也是难点。由于话题贴近学生生活实际，在学习的过程中，结合女孩Mary 的bad day的情景讲述，很容易激发学生的同感并引起其学习兴趣。
