教学过程(表格描述)
教学环节 主要教学活动 设置意图
导入1 （PPT 3） 观看视频，回答问题。Why is it hard to say goodbye to certain things 该对话是谈论个人旧物，引出今天要学习的语法重点—现在完成时态和写作话题—童年旧物。
语法学习1 （PPT 4-6） 1.观察时间轴，体会对话中三个动作所处的时间和完成情况；2.比较一般现在时、一般过去时和现在完成时的时态含义。3. 了解现在完成时的意义和构成。 通过时间轴直观展示对话中三个动作所发生的时间和完成的情况，引导学生将现在完成时与之前学过的一般现在时和一般过去时进行对比。
练习1 （PPT 7-8） 通过填空题进行时态练习，区别一般现在时和现在完成时。 讲练结合，加深学生对现在完成时的意义和构成的理解。
语法学习2 （PPT 9-10） 跟读课本Grammar Focus表格，观察现在完成时的时间状语，着重学习for和since在引导时间状语时用法上的异同。 承上启下 上述导入和语法学习环节是对于现在完成时态基础知识的学习，这里给出具体表达方式并进一步聚焦到for和since用法的学习。
语法学习3 （PPT 11-12） 复习动词分类，重点复习状态动词、延续性动词和瞬间性动词。判断8个使用现在完成时的句子是否正确。 选用句子的谓语动词分别为状态动词、延续性动词或瞬间性动词，引导学生得出结论 — 当用现在完成时的肯定句和how long引导的疑问句表示持续性动作和状态时应使用延续性动词。
练习2 （PPT 13） 将瞬间性动词转换为对应含义的延续性动词。 当用现在完成时的肯定句和how long引导的疑问句表示持续性动作和状态时应使用延续性动词。此环节既能巩固学生对用于延续性和瞬间性动词的理解，也为后续练习提供支持。
写作学习1 （PPT 14-17） 用for或者since合并改写句子。 通过将一个一般现在时态的句子和一个一般过去时态的句子合并改写成一个现在完成时的句子，加深对现在完成时态的含义、构成和for或since引导时间状语的理解，学习写作时态正确的句子。
练习3 （PPT 18-19） 书上4a练习题，用for或since改写句子。 此环节既能巩固所学，也为后续练习提供支持。
练习4 （PPT 20-22） 根据课本4c练习题中的表格完成对话、采访家人“What’s your favorite thing？” 承上启下 既加深对现在完成时态的理解，又通过口头练习为后续写作学习搭建阶梯。
导入2 （PPT 23） Think and talk.“What’s your favorite thing from childhood ” 引入写作话题。
写作学习2 （PPT 24-27） 通过回答问题准备写作素材、连词成句、连句成段、连段成篇。 通过问题引导学生进行写作。
写作学习3 （PPT 28-34） 运用所学知识改进写作文章。 引导学生通过检查语法、升级表达词句、添加相关信息、增强逻辑性和添加主题句的方式提升表达效果。
知识小结 （PPT 35） 总结改进写作的五个方法 带领学生梳理所学知识，形成条理帮助记忆。
