五、教学反思：

本节课以教授和操练社区有关的单词、词组和句型为中心，在上课之前，我先放了一首“Turn Right, Turn Left〞目的是创设一个轻松愉悦的气氛，目的是让学生熟练掌握方向的表达法及熟练反响出左右方向。

为了增强语言的真实性，使学生有身临其境之感，我让学生充分利用身边的教学资源，在教学时采用直观手段，如学习单词“pass〞 和“cross〞时直接利用教室里的空间关系加深学生印象，为学生创设语言环境。让学生们在直观，具体的过程中学习语言、运用语言，调动学生的学习积极性，提高了课堂教学的效率。在最后一局部局部，我也根据书中已有的场景，带着学生在具体场景中进行对话。

本课的各个环节很融洽地结合在一起，情景自然，过度流畅。在设计小组活动时，注意到了学生能力的差异，允许他们自行选择所编对话的内容及数量，表达了分层教学的理念。最后拓展稳固环节让学生在真实的情景中灵活运用所学句型，既激发的学生的学习兴趣又稳固了本课句型。
