(我现在不饿) 强调过去动作的现在影响。 定义2​ 表示过去开始，持续到现在的动作或状态，常与 for/since 等连用。 I have lived here for 3 years. (现在还住) 强调动作或状态的持续性。 肯定句​ 主语 + have/has​ + 动词过去分词 (p.p.)​ + 其他。 I/You/We/They have worked. He/She/It has worked. have/has 是助动词，has 用于三单。 否定句​ 主语 + have/has + not​ + 过去分词 + 其他。 I have not (haven't) finished. He has not (hasn't) come. not 加在 have/has 之后。 一般疑问句​ Have/Has​ + 主语 + 过去分词 + 其他? Have​ you seen​ it? Has​ he arrived? 将 have/has 提至句首。 简略回答​ Yes, 主语 + have/has. / No, 主语 + haven't/hasn't.​ —Have you eaten? —Yes, I have. 用 have/has 回答，不用动词原形。 二、动词过去分词 (Past Participle) 的构成 分类 规则 示例 (原形 → 过去式 → 过去分词) 考点提示 规则变化​ 同动词过去式规则，在词尾加 -ed。 work → worked → worked live → lived → lived study → studied → studied stop → stopped → stopped 规则动词的过去式和过去分词同形。 不规则变化​ 无统一规则，必须背诵不规则动词表。常见有： 1. AAA型: put→put→put 2. ABB型: buy→bought→bought 3. ABA型: come→came→come 4. ABC型: go→went→gone see→saw→seen eat→ate→eaten have→had→had do→did→done 必须熟记常用不规则动词的“三单”形式。 三、常考时间状语 (信号词) 与用法 时间状语 含义与用法 在句中的位置 示例 考点与辨析 already​ 已经 (多用于肯定句)。 句中 (have/has 之后) 或句末。 I have already​ finished. 在疑问句中表示惊讶：Have you finished already? yet​ 1. 还，尚 (用于否定句)。 2. 已经 (用于疑问句)。 通常放在句末。 He hasn't come back yet. Have you done it yet? 否定句/疑问句中，already 要改为 yet。 ever​ 曾经 (多用于疑问句)。 句中 (have/has 之后)。 Have you ever​ been to Beijing? 询问“人生经历”。 never​ 从未 (用于肯定句，表否定意义)。 句中 (have/has 之后)。 I have never​ seen him. never 本身表否定，不再加 not。 just​ 刚刚。 句中 (have/has 之后)。 He has just​ left. 表示动作刚发生，对现在有影响。 for + 时间段​ 长达…… (表示动作持续了多久)。 句首或句末。 I have lived here for 3 years. 回答 How long...?​ 提问。 since + 时间点​ 自从……以来。 句首或句末。 He has worked here since 2020. since 后接过去某一具体时间点。 since 与 for 的转换：since + 时间点 = for + 时间段 例：since 2021 = for three years (假设现在是2024年) 四、延续性动词与非延续性动词的转换（核心难点） 类别 定义 常见动词 与时间状语连用 考点 延续性动词​ 动作可以持续一段时间。 live, work, stay, know, have (有), keep 可与 for/since​ 等表示一段时间的状语连用。 是现在完成时表示“持续”的主力军。 非延续性动词​ 动作瞬间完成，不能持续。 buy, borrow, die, leave, open, close, come, go, join, finish 不能与 for/since 等表示一段时间的状语连用。 需转换为延续性动词或状态才能接 for/since。 ✅ 非延续性动词 → 延续性动词/状态的常考转换表： 非延续性动词 (瞬间) 延续性动词/状态 (持续) 例句转换 buy (买) have (拥有) He bought​ a car 3 years ago. → He has had​ the car for 3 years. borrow (借) keep (保留) I borrowed​ the book. → I have kept​ the book for a week. die (死) be dead (死的状态) His grandfather died​ 10 years ago. → His grandfather has been dead​ for 10 years. leave (离开) be away (from) (离开的状态) He left​ his hometown. → He has been away from​ his hometown. open (打开) be open (开着的状态) The shop opened. → The shop has been open. come/go/arrive (来/去/到) be in/at (在...的状态) He came​ to China. → He has been in​ China. join (加入) be a member of / be in (是...成员的状态) He joined​ the club. → He has been a member of​ the club. begin/start (开始) be on (进行的状态) The film began. → The film has been on. 五、重点、易错点与常考点精析 类别 易错点 正确用法 记忆技巧/规则 have/has 选择​ 第三人称单数用 has He has​ done it. 口诀：他/她/它，用has。 过去分词形式​ 误用动词原形或过去式 I have seen​ (not see/saw) it. 结构：have/has + 过去分词 (p.p.)。 时间状语混淆​ 与一般过去时时间状语混淆 I have seen​ him today. (现在完成时，today未完) I saw​ him this morning. (一般过去时，morning已过) 现在完成时常用不明确的过去时间或包含现在的时间段。 非延续动词接 for​ 非延续动词直接接 for/since ❌ He has died for 10 years. 必须转换：He has been dead for 10 years. have been to/gone to​ have been to: 去过，已回。 have gone to: 去了，未回。 He has been to​ Paris. (现在不在巴黎) He has gone to​ Paris. (现在在巴黎或路上) 口诀：been 是经历，gone 是人已去。 六、速记卡片 ✅ 结构：have/has + 过去分词 (p.p.) ✅ 用法： 1. 过去动作，现在影响 (just, already)。 2. 过去开始，持续现在 (for, since)。 3. 过去经历，不问时间 (ever, never)。 ✅ 标志词： - 肯定句：already, just - 否定/疑问句：yet - 问经历：ever - 表持续：for + 时间段，since + 时间点 ✅ 难点： - 非延续动词 (buy, die) 接 for/since 时必须转换 (have, be dead)。 - have been to (去过)， have gone to (去了未回)。 ✅ 解题步骤： 1. 找时间状语，判断时态。 2. 看主语，选 have/has。 3. 写对过去分词 (规则/不规则)。 4. 检查非延续动词是否需转换。 八年级上册 Unit5能力提升综合练习卷 答案 一、单项选择题 题号 答案 解析 1 C 询问"曾经是否去过"，用现在完成时 Have you ever been to...?，have been to 表示"去过（已回）"。 2 C for three years 表示持续，用现在完成时；人还在伦敦，用 has been in（一直在）。 3 B "父亲去了超市还没回来"，用 has gone to，表示"去了未回"。 4 C yet 用于现在完成时的否定句，填 haven't finished。 5 D for ten years 表示持续，die 是非延续性动词，需转换为 be dead 的延续状态，用 has been dead。 6 C since she was six 表示"自过去某时间点至今"，join 是非延续性动词，需用 has been in 表示"是俱乐部成员的状态"。 7 C How long 询问持续时间，buy 是非延续性动词，需用 have 的延续形式，填 have had。 8 B for half an hour 表示持续，begin 是非延续性动词，需用 be on 的延续状态，填 has been on。 9 C since 引导的时间状语，主句用现在完成时 Have you met。 10 C since they got married 表示从过去某时间点持续到现在，用现在完成时 have lived。 11 A host family 寄宿家庭，交换生住在寄宿家庭。 12 A 初到异国他乡，对一切不熟悉，会感到 homesick（想家的）。 13 A 看到奇怪的食物，脸上露出"震惊"的表情，shock 符合。 14 A 外国学生在中国要学会使用 chopsticks（筷子）。 15 A 应对文化冲击，需要 adapt to（适应）新环境。 16 A 交换生在旅行中将 take part in（参加）许多旅游景点活动。 17 A get along with 与……相处，与寄宿家庭相处融洽。 18 A be grateful for 对……心怀感激，感谢寄宿父母的照顾。 19 A can't wait to do sth 迫不及待做某事，符合"迫不及待想亲眼看看长城"。 20 A keep in touch with 与……保持联系，和家里的亲人保持联系。 二、填空题 （A）首字母填空 题号 答案 解析 1 exchange 交换（exchange student 交换生） 2 nervous 焦虑的 3 grateful 感激的 4 chopsticks 筷子 5 tour 旅行 6 tai chi 太极（拳） 7 yet 还；尚（未） 8 independent 自主的 9 content 内容 10 feeling 感觉；感情 11 shock 震惊 12 foreign 外国的 13 confused 糊涂的；迷惑的 14 anxious 焦虑的；忧虑的 15 phase 阶段；时期 16 honeymoon 蜜月 17 unfamiliar 陌生的；不熟悉的 18 homesick 想家的 19 lonely 孤独的 20 deal; with deal with 解决；处理 （B）完成句子挖空题参考答案 题号 答案 解析 1 on; the on the way 在途中（2词短语） 2 At; first at first 起初（2词短语） 3 deal; with deal with 解决；处理（2词短语） 4 feels; at 或 felt; at feel at home 感到舒适自在（2词短语，主语 she 第三人称单数用 feels） 5 wait; to can't wait to do sth 迫不及待做某事（2词短语，wait to） 6 gets; along 或 got; along get along with 与……相处（2词短语，主语 she 用 gets） 7 keep; in keep in touch with 与……保持联系（2词短语，keep in） 8 adapted; to 或 adapts; to adapt to 适应（2词短语） 9 feel; like 或 feels; like feel like 想要（2词短语） 10 is; grateful 或 was; grateful be grateful for 对……心怀感激（2词短语，be grateful） （C）单句语法填空参考答案 题号 答案 解析 1 been Have you ever been to...? 现在完成时，be 的过去分词 been 2 has been for three years 表示持续，用现在完成时 has been 3 has gone "父亲去了超市未回"，用 has gone 4 haven't finished yet 用于现在完成时否定句 5 has been for ten years 表示持续，die 需转换为 be dead，用 has been dead 6 has been since 引导，join 需转换为 be in，用 has been in 7 have; had How long 提问，buy 需转换为 have，用 have had 8 has been for half an hour 表示持续，begin 需转换为 be on，用 has been on 9 Have; met since 引导，主句用现在完成时 Have you met 10 have lived since 引导，用现在完成时 have lived 11 to learn stay with sb to do sth 和寄宿家庭住在一起为了了解中国文化，不定式表目的 12 to visit plan to do sth 计划做某事 13 introduce make sb do sth 让某人做某事，省略 to 14 touring spend time doing sth 花费时间做某事 15 to deal need to do sth 需要做某事 16 seeing look forward to doing sth 期盼做某事，to 为介词 17 have taken since 引导，用现在完成时 have taken 18 Adapting 动名词作主语，adapt to 适应 19 to keep It is + adj. + for sb to do sth 对某人来说做某事是……的 20 Hearing 动名词作主语，hear from 收到某人的来信 1 学科网（北京）股份有限公司 $
