一：教材分析。
本单元以“ What were you doing when the UFO arrived”为课题。谈论如何使用过去进行时。如何使用过去进行时是本单元的重难点。通过观察图片,利用图片进行情景思维,学会讲故事,俩俩对话,角色扮演等形式和独立学习,合作交流,完成任务等来培养学生的综合语言运用能力,创新意识和实践能力。 教学理念
学会使用While 和when 引导的状语从句表示时间；学会运用过去进行时描述过去某个时刻正在发生的事情；学会按照一定的逻辑顺序讲述过往经历；讲述一段故事。在本单元的学习中，着重培养学生根据上下文把握文段整体意义的能力、恰当的语言表述能力和故事表演能力。 二：教学目标。

过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作，常和表过去的时间状语连用，如：
I was doing my homework at this time yesterday.昨天的这个时候我正在做作业。
They were waiting for you yesterday.他们昨天一直在等你。 过去进行时的构成：
肯定形式：主语+was/were+V-ing 否定形式：主语+was not (wasn’t)/were not (weren’t)+V-ing 疑问形式：Was/Were+主语+V-ing。 使用进行时态的注意事项
1）一些动词，如see、hear、love、like、know、remember；understand、have等表示感情、知觉和状态的词，一般不用于进行时态。 2）在there和here引起的句子中，常用一般现在时代替现在进行时。
eg.Here comes the bus .There goes the bell.
（二）、1.情态动词表示“应该”、“必须” （shall, should, may, might, must, ought to）
2.情态动词表示“意图”、“打算” (will, would, shall, should) 3.情态动词表示“意愿” （will, would, shall, should）
