学习能力 1. 学会 “观察例句 — 归纳语法规则 — 对比辨析时态 — 语境实操” 自主学习方法； 2. 独立完成填空、句型转换、写作表达，主动梳理易混时态、短语（used to/be used to/get used to）。
文化意识 依托贵州交通、乡村发展话题，感受家乡建设成就，能用英语介绍家乡变迁，树立家乡自豪感；辩证看待发展带来的利弊，树立绿色可持续发展观念。
思维品质 通过对比三种时态时间线、语义差异，锻炼归纳、辨析逻辑思维；辩证分析发展的优缺点，创造性运用语法表达个人观点，提升思辨与创新表达能力。
二、教学重难点
教学重点
used to do、一般过去时、现在完成时的结构、标志词、基础用法；
2. for/since、yet/just/ever 的搭配使用；
3. 在短文、对话中结合 “家乡变化” 主题综合运用三种时态。
教学难点
区分一般过去时（动作完全结束，与现在无关）与现在完成时（动作关联现在、持续至今）；
辨析 used to do /be used to doing /be used to do 三组易混短语；
结合话题辩证输出观点，灵活混合时态描写今昔对比。
三、教学准备 多媒体课件、乡村新旧图片、时态时间线板书、课堂练习单
四、教学过程
Step1 Lead-in 导入
展示两组图片：①过去土路、矮瓦房；②现在高速大桥、高楼新村。
出示两组例句，学生判断时态：① He had breakfast at home yesterday.（一般过去时）② I have finished my homework already.（现在完成时）
3. 引出核心问题：如何用英语描述过去习惯、过去发生的事、持续到现在的变化？点明本课三大时态。
Step2 Presentation
一般过去时结构：主语 + 动词过去式；标志词 yesterday/last…/…ago；含义：过去完结动作，和现在无联系，结合乡村采访例句讲解。
现在完成时结构：have/has + 过去分词；标志词 already/yet/just/for/since；两层含义：①过去动作对现在有影响；②动作从过去持续到现在；搭配时间线图示区分与一般过去时。
used to do结构：主语 + used to do；含义：过去习惯 / 状态，现在不再如此；but now 表今昔对比；拓展否定、疑问句式。
易混短语辨析used to do（过去常常）/be used to doing（习惯于）/be used to do（被用来），配图例句巩固。
Step3 Grammar Practice
基础单选：时态、短语辨析选择题；
句型转换：一般过去时与现在完成时互换（for/since 改写）；
课本 4b 对话填空：师生核对，讲解 have been to、read 过去式等重难点；
课本 4c 短文填空（贵州交通变迁），小组讨论核对答案，梳理乡村发展线索。
Step4 Think & Creative Output
讨论 1：是什么带来家乡变化？（政府建设、工人、父母努力），用现在完成时造句；
辩证思考：发展有利也有弊（修路破坏植被、快餐便利但不健康）；
小组口头输出：结合 used to + 现在完成时，介绍自己家乡一处变化，抒发自豪感。
Step5 Summary & Homework
课堂小结：表格梳理三种时态结构、标志词、核心区别；
分层作业：必做：订正 4b、4c 错题；选做：采访同学社区变化，写 5 句英语描述。
