学习目标
通过本节课学习，学生能够：
准确识别现在完成时中 “fr”（接时间段）和 “since”（接时间点 / 过去式从句）的用法规则，区分延续性动词与非延续性动词的差异，掌握非延续性动词转化为延续性动词的常见形式，并能从课文或例句中提取相关语法结构，理解其语义功能。(学习理解)
运用“fr”和“since”正确完成句子填空、短文补全等练习，在单项选择中准确判断延续性动词与非延续性动词的使用场景，还能以小组为单位，借助 “have ” 等常用表达，围绕 “分享经历” 进行简单口语交流，清晰说明事件时间、过程与感受。（实践运用）
能将所学语法知识迁移到生活场景中，如用现在完成时结合“fr/since”描述个人与朋友的相处时长、兴趣爱好的坚持时间等，还能通过对比中西方餐桌礼仪，思考文化差异下的人际交往方式，深化对“分享”主题的多元理解，并尝试用所学语言记录相关感悟。（迁移创新）
