Unit 10 I've had this bike for three years 复习讲义 一、核心知识点精讲 1. 现在完成时表示持续状态（for/since） 结构： 肯定句：主语 + have/has + 延续性动词过去分词 + for/since + 时间 否定句：主语 + have/has + not + 延续性动词过去分词 + for/since + 时间 重点： for + 时间段（three years, two months） since + 时间点（2018, last summer） 非延续性动词必须转换： buy → have had | borrow → have kept | die → have been dead 例题1 Q: My grandparents _____ (live) in this village _____ 50 years. A. have lived; for B. lived; since C. have lived; since 解析 选A。live为延续性动词，"50 years"是时间段，用for。 2. how long 对持续时间提问 结构： How long + have/has + 主语 + 延续性动词过去分词 回答： For + 时间段 / Since + 时间点 易错点： 非延续性动词需转换后使用： How long have you bought the book How long have you had the book 例题2 Q: —_____ have you owned this camera —_____ 2019. A. How long; Since B. How often; For C. How soon; In 解析 选A。how long询问持续时间，回答用since + 时间点。 3. 物品处理与情感表达 必会词汇拓展表达 yard sale（庭院拍卖） donate, second-hand part with（放弃） memory, childhood repair（修理） valuable, sentimental 例题3 Q: I can't _____ my old teddy bear. It reminds me of my happy childhood. A. give up B. part with C. throw away 解析 选B。part with表示“放弃（有情感价值的物品）”。 二、语法专题：延续性动词与非延续性动词转换 转换对照表 非延续性动词延续性动词/状态表达例句（现在完成时） buy have/has had I have had this bike for 3 years. borrow have/has kept She has kept the book for a week. die have/has been dead The dog has been dead since 2020. 易错点突破： 短暂性动作不能与for/since连用： He has joined the club for two years. He has been a club member for two years. 例题4 Q: Mr. Wang _____ (teach) in our school _____ he graduated. A. has taught; since B. taught; for C. has taught; for 解析 选A。teach为延续性动词，since后接时间点（graduated）。 三、题型解题技巧 1. 完形填空：动词时态与时间状语匹配 技巧步骤： 判断动词类型（延续性/非延续性） 根据for/since选择正确时态 例题5 Q: I _____ (buy) this watch five years ago, and I _____ (keep) it ever since. A. bought; have kept B. have bought; kept C. bought; keep 解析 选A。第一空有具体时间（five years ago）用一般过去时；第二空ever since用现在完成时，keep为延续性动词。 2. 阅读理解：情感态度推断 步骤： 划出描述情感的形容词（sentimental, unforgettable） 注意表达情感的动词（remind, miss, cherish） 例题6（根据短文） Q: Why does the writer keep the old photo album A.
