I went to Beijing in 2019. 我在2019年去了北京。 二、 动词过去式构成 (复习与拓展) 1. 规则动词 (+ -ed) work → worked study → studied (辅音+y, 变y为i+ed) stop → stopped (重读闭音节，双写尾字母+ed) 2. 常见不规则动词 (必须熟记) be → was/were do → did have → had go → went see → saw take → took come → came get → got write → wrote read → read (读音变为 /red/) put → put (不变) cut → cut (不变) 九年级要求： 熟练掌握至少50个常用不规则动词的过去式。 三、 句式结构 (Sentence Structures) 1. 肯定句: 主语 + 动词过去式 (+ 时间状语). She passed the exam. 她通过了考试。 2. 否定句: 主语 + did not (didn't) + 动词原形. She did not (didn't) pass the exam. 核心考点： 助动词 did 已经体现了过去时态，主要动词必须用原形。 3. 一般疑问句: Did + 主语 + 动词原形 Did she pass the exam — Yes, she did. / No, she didn't. 4. 特殊疑问句: 特殊疑问词 + did + 主语 + 动词原形 When did she pass the exam 四、 核心考点辨析：一般过去时 vs. 现在完成时 这是九年级及中考的核心难点。 时态 一般过去时 (Simple Past) 现在完成时 (Present Perfect) 关键词 yesterday, last week, ... ago, in 1990 just, already, yet, ever, never, since, for 焦点 动作发生的时间 (过去某时) 动作产生的影响或结果 (现在如何) 与现在关系 无关，动作已彻底结束 有关，动作影响持续到现在 例句 I saw that movie last year. (我去年看了那部电影。强调“看”的时间是去年。) I have already seen that movie. (我已经看过那部电影了。强调“现在我知道内容了”。) 例句 He lived here for ten years. (他现在不住这了) He has lived here for ten years. (他现在还住这) 五、 高级应用：宾语从句中的时态呼应 当主句谓语是过去时（如 said, told, knew, thought等）时，宾语从句的时态通常要用相应的过去时态。 现在时 → 过去时 He said, "I am busy." → He said (that) he was busy. 现在完成时 → 过去完成时 She said, "I have finished my work." → She said (that) she had finished her work. 一般过去时 → 过去完成时 或 不变 (如果强调动作本身发生在从句动作之前，用过去完成时；如果只是客观转述，也可用一般过去时) He said, "I saw the film yesterday." → He said (that) he (had) seen the film the day before. 注意： 如果宾语从句表述的是客观真理，则时态不变。 The teacher said (that) the earth goes around the sun. 1．Our English teacher, Mr. Ma, _____ English on the radio the day before yesterday.
