She has lived here for 2 years. 【for+时间段】的区分对比 一般过去时+for：时长只属于过去，现已结束； 现在完成时+for：时长连接过去到现在，状态延续。 她以前在这住两年，现在搬走了。（一般过去时，居住行为彻底终止于过去） 她在这住了两年，现在还住这。（现在完成时，居住状态持续至当下） 13 判断正误： I have finished my homework yesterday. I finished my homework yesterday. I have finished my homework. 能否搭配具体过去时间（超级易错点） 一般过去时： 可以加精确过去时间 现在完成时： 绝对不能加yesterday / last week / ...ago 这类具体过去时间 14 PART 03 基 本 结 构 对 比 15 ① 主语 + 动词过去式 + 其他 （肯定句） ② 主语 + didn't + 动词原形 （否定句） ③ Did + 主语 + 动词原形？ （一般疑问句） Yes, 主语 + did./ No, 主语 + didn't. 特殊疑问词 + did + 主语 + 动词原形 + 其他？（特殊疑问句） 一般过去时基本结构 16 ① 主语 + have/has + 动词过去分词 （肯定句） ② 主语 + haven't/hasn't + 过去分词 （否定句） ③ Have/Has + 主语 + 过去分词？ （一般疑问句） 助动词选择： 第三人称单数(he/she/it/单数名词)用has，其余全部用have 现在完成时基本结构 17 I saw a movie yesterday. 例 句 对 比 看过电影，现在我知道剧情了 → 现在完成时 昨天看电影，过去动作结束 → 一般过去时 I have seen the movie. 18 一般过去时 问句：Did you eat breakfast? 回答：Yes, I ate at 7 a.m. 回答逻辑对比 现在完成时 问句：Have you eaten breakfast? 回答：Yes, I'm full now. 回答过去几点吃的 回答现在饱了这个结果 19 PART 04 动 作 特 征 对 比 20 1. 有明确、具体的过去时间。 2. 动作完全完结，现在不存在。 3. 只描述过去事实，不关心现在情况。 一般过去时三大特点 自行车现在坏了、丢了都无所谓，句子只陈述上个月的行为。 He bought a bike last month. 他上个月买了自行车 21 现在完成时四大场景 场景1：过去动作→现在 存在结果 I have read this book three times. 这本书我总共读了三遍。 I have lost my key. 我钥匙丢了（结果：我现在打不开门） 场景2：动作从过去开始，持续到现在（常搭配for/since） I have lived here for 5 years. 我住这儿5年了（现在依然住在这里） 场景3：人生经历，到目前为止的履历 Have you ever been to Kenya? 你去过肯尼亚吗？（问至今的经历） 场景4：过去重复动作，累计到现在 22 PART 05 高频易混词组辨析 23 She has been in Beijing for a month. 易 混 词 组 辨 析 have gone to：去了某地（人现在还在目的地，没回来） —Where is Tom? —He has gone to Shanghai. 汤姆去上海了。 have been to：去过某地（现在已经返回，谈经历） I have been to Shanghai twice. 我去过上海两次。 have been in /at + 某地 ：待在某地多久（延续状态） 24 have been to 去过某地，人已经回来 可和just/ever/never/once等次数词搭配 have gone to 去了某地，人还未返回 多用于第三人称，绝对不能搭配for+一段时间 have been in/at 在某地停留、居住 表持续状态，搭配延续性时长 总 结 25 有时状(yesterday/ago)用过去， 无时间看结果用完成； 过去只说旧事情， 完成连接现如今； for加时段要注意， 过去结束完成续。 做 题 口 诀 26 PART 06 拔 高 巩 固 练 习 27 小 试 牛 刀 1. —________ you ________ the mountain town last summer? —Yes.
