小升初专项复习------一般过去式知识点+练习（含答案）

小升初专项复习--一般过去时 一、核心知识点 1. 基本概念 表示过去发生的动作或状态（已完成），常搭配明确的过去时间标志。 标志词：yesterday, last night/week/month, ...ago, in 2020, just now（刚才）等。 2. 结构公式 句型 结构 例句 肯定句 主语 + 动词过去式 She watched a movie last night. 否定句 主语 + did not (didn't) + 动词原形 They didn't play football yesterday 疑问句 Did + 主语 + 动词原形 Did you finish homework 二、动词过去式变化规则（重难点！） 规则 动词原形 过去式 记忆要点 直接加 -ed play played 大部分动词 以 e 结尾，加 -d live lived smile → smiled 辅音+y结尾，变y为i+ed study studied carry → carried 重读闭音节结尾，双写尾字母+ed stop stopped 条件：辅-元-辅结尾（plan → planned, shop → shopped） 不规则变化（必背高频词） 三组变形规律： 1. AAA型：cut→cut, put→put, hit→hit 2. ABB型： buy→bought, think→thought（ought派） bring→brought, catch→caught（aught派） teach→taught, keep→kept（变元音+尾音） 3. ABC型：go→went→gone, see→saw→seen, do→did→done 小升初必背30个不规则动词： be (was/were) → have (had) → eat (ate) → write (wrote) → take (took) → come (came) → run (ran) → sing (sang) → get (got) → give (gave) → drink (drank) → fly (flew) 三、解题技巧（三步锁定答案） Step 1: 抓时间标志词 看到以下词，优先考虑一般过去时：yesterday, last night, ...ago, in 2010, just now, this morning Step 2: 查动词形态 肯定句 → 动词必须变过去式（规则/不规则） 否定句/疑问句 → 用 did/didn't + 动词原形（ 易错点！） Step 3: 辨句型结构 根据句子类型选择结构： 句型 结构特征 例句纠错 否定句 didn't + 动词原形 She didn't went home. 改正：She didn't go home. 疑问句 Did ... + 动词原形？ Did you saw him 改正：Did you see him 四、易错点深度剖析 1. 不规则动词混淆 误：He teached me English. 正：He taught me English. 对策：熟记不规则动词表（重点标红teach-taught, bring-brought等） 2. 否定句/疑问句中动词未还原 误：Did they played chess 正：Did they play chess 口诀： Did 现身，动词现原形！ 3. 过去式与过去分词混淆 误：I have ate breakfast. (现在完成时用过去分词 eaten) 正：I ate breakfast. (一般过去时) 区分：一般过去时无have/has，动词直接用过去式。 4. 时间标志词缺失导致时态误判 误：She visits her grandma. (无时间用一般现在时) 正：She visited her grandma last Sunday. 五、真题实战演练 1. 用动词过去式填空： They _____ (swim) in the sea yesterday afternoon. 答案：swam（不规则变化） 2. 改否定句： Tom did his homework last night. → Tom _____ _____ his homework last night. 答案：did not do / didn't do 3. 纠错题： "Did you went to the park " 改正 "Did you go to the park " 4. 写作运用： 翻译：我妈妈今早为我做了蛋糕。 答案：My mother made a cake for me this morning. 六、口诀记忆包 一般过去时判定口诀 "过去时间在眼前，动词变身记心间，Did问Did否帮忙，动词原形跟后面！" 不规则动词速记法 买买买（buy）带来（bring）战斗（fight），三兄弟ought不能少； 教（teach）捉（catch）追（catch）也疯狂，aught组合要记牢！终极提醒： 规则动词 双写/去y 是考试高频扣分点（stop→stopped, study→studied） 遇到 Did... / Didn't...，立刻检查动词是否还原！ 小升初专项复习--一般过去时专项练习题 一、写出下列动词 ... ...
