2025-2026学年仁爱科普版（2012）九年级英语上册暑假巩固复习-现在完成时

现在完成时 一、现在完成时核心考点梳理 1. 基本概念 现在完成时表示： 1） 过去发生的动作对现在造成的影响或结果（已完成用法）。 I have finished my homework.（已完成，现在可以休息） 2） 从过去持续到现在的动作或状态（未完成用法）。 He has lived here for 10 years.（仍在居住） 2. 结构 肯定句：主语 + have/has + 过去分词 She has seen the movie. 否定句：主语 + have/has + not + 过去分词 They haven’t visited Beijing yet. 疑问句：Have/Has + 主语 + 过去分词? Have you ever been to Shanghai? 3. 常用时间状语 不确定时间：already, just, yet, ever, never, before I have already eaten. 持续时段：for + 时间段, since + 时间点, how long, so far, in the past few years She has worked here since 2020. 4.过去分词变化规则： 规则动词：动词 + -ed（如：worked, played） 不规则动词：需单独记忆（如：go → gone, see → seen, eat → eaten） 附：常见不规则动词表（部分） be → been, do → done, write → written, break → broken 5.与一般过去时的区别： 现在完成时 一般过去时 强调动作与现在的联系（结果/持续） 例：I have lost my keys.（现在没钥匙） 仅描述过去发生的动作（与现在无关） I lost my keys yesterday.（仅陈述过去） 6. 延续性动词 vs. 短暂性动词 短暂性动词（如 buy, die, leave）不能直接与 for/since 连用，需转换为延续性表达： He has been dead for 3 years.（不能用 has died） I have had the book for a week.（不能用 have bought） 7. have been to / have gone to / have been in have been to：去过某地（已返回） She has been to Japan twice. have gone to：去了某地（未返回） Tom has gone to the library.（他现在不在这里） have been in：在某地停留一段时间 They have been in Shanghai for 5 years. 二、现在完成时专项练习 练习一：选择正确的时间状语 1.
