Unit 1 This is me! Understanding Ideas (Grammar) 导学案
学习目标 通过本节课学习，学生能够： 学生能够理解并总结现在完成时（含 yet、already 等标志词 ）的语法规则，准确识别阅读文本中同类结构句子。 能正确运用现在完成时结构（have/has + 过去分词 ），完成造句、改写句子等练习，提升语法运用准确性。 借助 “接纳自我经历” 相关语法练习与话题，引导学生关注自我认知，培养积极接纳自身特点（如身高、外貌等 ）的健康心态，增强自我认同感。
学习 重难点 重点： 理解现在完成时（have/has + 过去分词 ）的构成，精准把握 “yet”（常用于否定句、疑问句，表 “还；尚未” ）、“already”（常用于肯定句，表 “已经” ）的用法。 熟练运用现在完成时进行造句、改写句子 难点: 准确区分现在完成时和一般过去时，尤其在描述过去动作对现在影响时，能恰当选用时态；灵活运用 “yet”“already”，避免在肯定句、否定句、疑问句中混用，比如学生易在肯定句错用 “yet” 。
