Unit3 A Day to Remember一般过去时I Unit4 Once upon a Time一般过去时II 第一部分 一般过去时详细精讲 一、核心定义 一般过去时表示过去某个时间发生的动作或过去存在的状态，动作已经结束、不可延续、和现在没有关系。 本单元两大专属场景： 场景1：Unit3 A Day to Remember 过去经历/旅行记事 用于描述某次旅行、活动、一天的经历，全部是已经结束的过往事情。 例句：I visited the museum last weekend.（我上周末参观了博物馆。） 解析：last weekend 为过去时间，参观动作已经结束，用一般过去时。 场景2：Unit4 Once upon a Time 故事/童话往事 用于讲述很久以前的故事、寓言、人物经历，是记叙文绝对核心时态。 例句：Once upon a time, there lived a fisherman.（从前有一位渔夫。） 解析：once upon a time 纯过去时间标志，整篇故事统一使用一般过去时。 二、标志性时间状语 看到以下标志，直接锁定一般过去时： 1. 过去具体时间：yesterday（昨天）、last+时间（last week/last year）、just now（刚才） 2. 模糊过去时间：long ago（很久以前）、once upon a time（从前）、in the past（在过去） 3. 语境标志：故事叙述、日记回忆、已经结束的某次经历 例句：He made a promise long ago.（他很久以前许下了一个诺言。） 三、完整句子四大句型 核心通用公式：主语 +动词过去式+其他 关键特点：所有人称过去式不变形，I/you/he/we/they 动词过去式全部一样，不用区分单复数！（和现在进行时最大区别） 1. 肯定句 公式：主语+动词过去式+其他 例句1：We went on a trip last Sunday.（我们上周日去旅行了。） 解析：go 的过去式为不规则变化 went，过去时间动作已结束。 例句2：The duckling turned into a swan at last.（小鸭子最后变成了天鹅。） 解析：turn 规则变化加ed，at last 提示过去结局。 2. 否定句 公式：主语+ didn’t +动词原形+其他 超级重点：否定句和疑问句中，动词必须还原原形，不能用过去式！ 例句：He didn’t write down his feelings.（他没有写下他的感受。） 解析：didn’t 后 write 用原形，绝对不能写 wrote。 3. 一般疑问句 公式：Did +主语+动词原形+其他？ 回答：Yes, 主语 did. / No, 主语didn’t. 例句：—Did you explore the forest?（你探索森林了吗？）—Yes, I did. 解析：did 提前，后面 explore 必须还原原形。 4. 特殊疑问句 公式：特殊疑问词+ Did +主语+动词原形+其他？ 例句：What did you do during the trip?（你在旅途中做了什么？） 解析：疑问词后接一般疑问语序，do 还原原形。 四、动词过去式变形规则 1. 规则变化（大部分动词） ① 一般直接加 ed：work→worked、play→played、shout→shouted ② 不发音e结尾直接加 d：live→lived、like→liked、agree→agreed ③ 辅音+y结尾，变y为i加ed：study→studied、try→tried ④ 重读闭音节辅元辅结尾，双写尾字母加ed：stop→stopped、drop→dropped 2. 本单元必考不规则变化(全册不规则变化见课本附表) go→went、do→did、see→saw、say→said、make→made take→took、write→wrote、meet→met、become→became lie→lay、bite→bit、set→set、die→died 五、重难点易错精讲 易错点1：过去式单复数不变化 一般过去时没有单复数区别！ ❌ He wents there. ✅ He went there. 易错点2：did/didn’t 后面动词必还原原形（最大扣分点） ❌ Did you went there? ✅ Did you go there? 易错点3：一般过去时 vs 现在进行时 终极区分 ✅ 现在进行时：此时此刻正在做（be+doing） ✅ 一般过去时：过去已经做完，和现在无关 例句：It is raining now.（正在下） 例句：It rained yesterday.（昨天下过，现在停了） 易错点4：used to do 固定句型（Unit3超高频） 含义：过去常常做某事（现在不做了） 结构：used to + 动词原形 例句：He used to live near the theatre.（他过去住在剧院附近。） 易错点5：故事类文体全篇过去式 Once upon a time 开头的文章，所有动作动词一律用过去式，禁止混用现在时。 第二部分 专项配套练习 一、用所给单词的正确形式填空 1.
