Teaching Reflection【教学反思】本节课是第十二单元的起始课，通过听和说的活动让学生学会用when/before/by the time 引导的时间状语从句谈论过去的事件，学生在这节课中要掌握的重点单词、短语“unexpected，backpack，oversleep，give…a lift，by the time(that)”和重点句型“By the time I got up，my brother had already gotten in the shower.When I got home，I realized I had left my keys in the backpack.When I woke up it was already 8：00 a．m.！Before I got to the bus stop，the bus had already left.”都得到了很好的落实。
在处理课堂导学案的过程中，我觉得学生合作探究活动能否顺利完成，关键在于学生预习得怎么样，课前预习搞好了，课堂中我再采用一些激励机制，比如分组竞赛、小组合作等方式，课堂气氛就活跃起来了，学生们跃跃欲试，争先恐后，一节课的任务在不知不觉中就完成了。
