第七部分：教学建议与拓展活动

• 建议1：情境导入

  • 上课开始，播放一段暴风雨或其它突发事件（如地震、火灾）的短视频，然后立刻提问：“If this happened right now, what would you be doing?” 引导学生用 I would be... 现在进行时进行想象,然后自然过渡到过去进行时。

• 建议2：时间轴活动

  • 在黑板上画一条时间轴，标出几个时间点（如: 7:00 p.m., 8:00 p.m., 9:00 p.m.），让学生分组讨论并写出自己在昨晚这些时间点正在做的事情，然后进行分享,这能直观地展示过去进行时的用法。

• 建议3：故事接龙

  教师开头：“Last night, I was reading a book in my bed...” 然后让一个学生接着说：“...when suddenly, the lights went out.” 下一个学生接着说：“I was so scared that I...” 用这种方式，全班同学共同创造一个关于“突发事件”的故事,在互动中巩固语法。

• 建议4：拓展阅读

  提供一些关于自然灾害或历史性事件（如阿波罗11号登月、汶川地震等）的简短英文报道，让学生找出文中使用过去进行时的句子,并讨论为什么作者要用它。
