过去时与现在完成时
1. 理论依据
演绎法归纳法
2. 原因分析
①定式化的时态用法记忆。
he has lived in London for 3 years.
he has lived in London for 3 years.
(过去某个动作,现在不出现了)
②中文讲解影响学生对时态的理解。
her mother grew up in italy.
ow! i've cut my finger. it's bleeding.
过去时只是告知过去发生了什么
现在完成时主要强调现在的状态。
3. 呈现
①对比呈现
4. 活动设计(联系生活,练习梯度)
①visual situations
②identification exercises
③situational practice-短对话
④interactive task: stories behind photos -过去式
一张自己的照片进行互问互答的口头交流→展示
⑤task-ased activities: the right experience for the job - 现在完成时
阅读候选人简历→讨论人选→征集人选的条件→小组代表发言选出候选人
