学习目标
1. 掌握现在完成时定义、四种基础句型,能默写结构
2. 熟记现完标志性词汇,区分 already/yet 用法
3. 分清 have been to /have gone to /have been in 用法区别
4. 掌握短暂性动词与延续性动词完整转换表(中考必考)
5. 区分现在完成时 & 一般过去时核心差异
6. 熟记初中高频不规则动词过去式、过去分词
7. 完成分层易错题,规避高频失分点
一、现在完成时定义(填空)
现在完成时表示:动作发生在______,对______产生影响;或动作从过去持续到______。
两大用法:
① 完成用法:过去动作,留下现在结果,句中______(有 / 无)明确过去时间;
② 持续用法:动作从过去延续至今,常搭配______ + 时间段 / ______ + 过去时间点 / 一般过去时从句。
二、基本句型结构(背诵挖空)
1. 肯定句
公式:主语 + ______ / ______ + 动词______(简写 done)
人称判断:______(he/she/it/ 单人 / 单数名词)用 has;其余人称用 have
例句:She ______ (finish) her homework.
2. 否定句
公式:主语 + have /has + ______ + 过去分词
缩写:have not = ______;has not = ______
例句:They ______ (not see) the giant’s garden yet.
3. 一般疑问句
公式:______ / ______ + 主语 + 过去分词?
简答:Yes, 主语 + have/has./ No, 主语 + haven’t/hasn’t.
例句:______ you ______ (read) the story before?
4. 特殊疑问句
公式:特殊疑问词 + have/has + 主语 + ______?
例:How long ______ you ______ (live) here?
三、现在完成时标志词(填空记忆)
第一组:表 “完成、经历”
1. already:______,用于______句,放在 have/has______
2. yet:已经 / 还,用于______句、______句,放句______
3. just:______,肯定句中
4. ever:______,多用于疑问句;never:______,本身表否定
5. before:______,放句末
第二组:表 “持续时长”
1. for + ______
2. since + ______ / ______(从句用一般过去时)
四、三大易混短语(填空区分)
1. have gone to + 地点:去了某地,人______(在 / 不在)现场,未返回
2. have been to + 地点:______某地,现已回来,常搭配次数 once/twice
3. have been in + 地点 + for/since:______某地一段时间,表持续状态
填空:
—Where is Tom?
—He ______ ______ ______ the library.
I ______ ______ ______ Beijing twice.
She ______ ______ ______ this school for 3 years.
五、核心重难点:短暂性动词 ↔ 延续性动词完整对照表(背诵)
提示:for/since 表示一段时间,不能直接使用短暂动词,必须替换为对应延续表达
短暂性动词(瞬间动作,不可与 for/since 连用)
对应延续性表达(可接时间段)

______
borrow
______
die
______
leave / go away
______

六、现在完成时 vs 一般过去时(填空区分)
1. 一般过去时:动作仅发生在过去,和现在无联系;句内常有明确过去时间词:______、______、______、…ago。
2. 现在完成时:侧重过去动作对现在的影响,______(有 / 无)具体过去时间,标志词:for/since/already/yet/ever 等。

He left yesterday.(______时态)
He has left.(______时态)
