Unit 1 A Changing World Grammar in Use：【Present perfect tense 现在完成时】 语法讲解（二） 一、基础核心定义 1. 含义 现在完成时连接过去动作与现在结果，核心两大用法（本课重点）： 1）过去发生的动作，对现在造成影响/结果（无明确过去时间） 2）从过去持续到现在的动作/状态（常搭配for/since） 2. 基本结构（必背） 肯定句：主语 + have / has + 动词过去分词(done) • 主语三单(he/she/it/单数人名/单数名词) → has • 主语I/you/we/they/复数名词 → have 例：I have finished my homework. 我写完作业了。（现在不用写了） He has lost his key. 他丢了钥匙。（现在没钥匙） 否定句：主语 + have / has + not + done have not = haven’t；has not = hasn’t 例：She hasn’t cleaned the room. 一般疑问句：Have / Has + 主语 + done? 回答：Yes, 主语+have/has. / No, 主语+haven’t/hasn’t. 例：Have you eaten breakfast? Yes, I have. / No, I haven’t. 特殊疑问句：Wh-疑问词 + have/has + 主语 + done? 例：Where have you been? 二、动词过去分词变化规则（中考必考） 1. 规则变化 1. 一般动词直接加-ed：work → worked；clean → cleaned 2. 以e结尾只加-d：live → lived；finish → finished 3. 辅音+y结尾，变y为i加-ed：study → studied 4. 重读闭音节（辅+元+辅）双写尾字母加-ed：stop → stopped 2. 不规则变化（高频必考，分模块） 1. AAA型（原形/过去式/过去分词相同） cut-cut-cut；put-put-put；read-read-read 2. ABB型（过去式=过去分词） finish-finished-finished；lose-lost-lost；buy-bought-bought 3. ABC型（三者全不同） do-did-done；go-went-gone；see-saw-seen；eat-ate-eaten 三、两大核心用法精讲（本课重点） 用法1：过去动作，影响现在（无具体过去时间） 标志词：already, yet, just, ever, never, before 1. already 已经（肯定句，句中/句末） I have already seen this film. 2. yet 已经/还（否定、疑问句，放句末） Have you read the book yet? / I haven’t read it yet. 3. just 刚刚（动作刚结束） He has just left. 4. ever 曾经（疑问句）；never 从不（否定含义） Have you ever been to Beijing? I have never visited Beijing. 5. before 以前（句末，无具体时间） I have met him before. 关键区分：一般过去时 VS 现在完成时 • 一般过去时：有明确过去时间(yesterday/last week/...ago)，只讲过去 I saw this movie yesterday.（单纯昨天看了） • 现在完成时：无过去时间，强调现在结果 I have seen this movie.（我看过，现在知道剧情） 用法2：动作从过去持续到现在（延续性动词） 标志词：for + 时间段；since + 时间点/过去句子 1. for + 时长：for 3 years, for two hours 2. since + 年份/日期/过去动作：since 2020, since last Monday, since I was 10 例：I have lived here for 5 years. We have studied English since Grade 7. 重难点：短暂性动词 ↔ 延续性动词（考试高频坑点） 短暂动词不能和for/since连用，必须换成延续动词 短暂动词 对应延续单词/短语 中文 buy have 买（拥有） borrow keep 借 die be dead 去世 leave be away 离开 begin/start be on 开始 join be in/be a member of 加入 come/go/arrive be in/at 到达 例：He bought the bike 2 years ago. = He has had the bike for 2 years. 四、固定句型 & 高频短语 1. have/has been to：去过某地（现在已回来） I have been to Shanghai twice. 2. have/has gone to：去了某地（人还没回来，不在现场） —Where is Tom? —He has gone to Shanghai. 3. have/has been in：待在某地持续多久（搭配for/since） He has been in Shanghai for a month. 4. have trouble/difficulty (in) doing sth 做某事有困难 5. so far 到目前为止（现在完成时标志） So far, we have learned 10 units. 五、易错点总结 1. 时间状语陷阱：出现yesterday, last night, ...ago 只能用一般过去时，不能用现完 2. yet只用于否定、疑问；already多用于肯定句 3. for后接时间段，since后接时间起点，不可混用 4. 短暂动词不能与for/since连用，必须替换延续动词 5. has用于第三人称单数，主语复数/I/you统一用have 【Present perfect tense 现在完成时】 语法练习（二） 一、基础默写：写出动词过去分词（30题） 规则动词 1. work ________ 2. clean ________ 3. finish ________ 4. live ________ 5. study ________ 6. stop ________ 7. play ________ 8. watch ________ 9. like ________ 10. carry ________ 不规则高频动词 11. do ________ 12. go ________ 13. see ________ 14. eat ________ 15. lose ________ 16. buy ________ 17. cut ________ 18. put ________ 19. read ________ 20. speak ________ 21. write ________ 22. break ________ 23. know ________ 24. forget ________ 25. take ________ 26. come ________ 27. leave ________ 28. begin ________ 29. die ________ 30. borrow ________ 二、用have/has填空（15题） 1.
