this
bike
for
three
years.
(Grammar
Focus-4c)
本课分析
本节课是本单元的第三课时，是以语法内容为核心整体设计的部分。重点语法项目是带有since和for
的现在完成时的句子。Grammar
Focus表格总结了本单元的典型例句，包括由How
long
引导的现在完成时的特殊疑问句，分别用for和since回答的例句，还有现在完成时的一般疑问句。
学情分析
经过了本单元前面的学习后，学生对于由how
long引导的现在完成时问句和含有since
与for的答语有一定的知识基础。小部分同学对于本部分的语法知识掌握比较好，但是大部分同学对于since与for后面所接内容和持续性动词与非持续性动词区分不清。

设计意图：小组活动增加学生合作意识，将所学内容应用于真实情景，引导学生不仅要关爱他人，更要关爱身边的父母朋友等。
活动一为一人报告，活动二为全员参与对学生要求更高。
本部分设计两个小组活动备选，如果学生层次不是特别好可以采用活动一；学生英语基础不错，选择活动二。上课过程中时间充裕可以多几组同学展示，时间不够可以只展示两组，灵活确定。
教学助手使用：移动讲台，手机播放控制ppt。计时。拍摄小组成员照片，实时上传，让同学们更有新鲜感，有组员意识。
反思：本节课的类型为语法课。传统语法的最大弊端就是枯燥乏味，本设计通过各种活动方式将原本枯燥乏味的语法课变得有趣。以组织庭院售卖为主线完成各项活动，以慈善为目标教育学生懂得关爱他人与身边的人，线索清晰课程流畅。但是含有since和for的现在完成时是非常难的语法点，不能够仅仅一节课解决所有问题。需要在以后的教学中不断的更正讲解。
