Unit 10 Lending a Helping Hand-同步【语法】-一般过去时II-复习和练习 目录 【同步语法复习】 2 一、核心语法:一般过去时(Ⅱ) 2 二、中考高频考点 3 三、易错点 & 易混点 4 四、实用记忆口诀 4 五、本单元核心句型 5 六、单元 chant 核心动词过去式汇总 5 【同步语法练习】 5 一、按要求改写句子(每空一词) 5 二、用所给动词的适当形式填空 6 三、中考真题单项选择 6 四、下列句子均有一处错误,请改正 7 五、按要求改写句子(每空一词) 7 参考答案和解析 7 【同步语法复习】 一、核心语法:一般过去时(Ⅱ) 本单元聚焦一般过去时中 be 动词与实义动词的一般疑问句、否定句及特殊疑问句,是中考的基础必考点。 1. 核心定义 表示过去某个时间发生的动作或存在的状态,常搭配时间状语:last weekend/ yesterday/ just now/ at that time/ in the past 等。 2. 核心结构(本单元重点) (1)be 动词(was/were)的过去式 人称 / 单复数 过去式 一般疑问句 肯定 / 否定回答 I/he/she/it was Was he/she in Shanghai yesterday? Yes, he/she was. / No, he/she wasn’t. we/you/they were Were they at home just now? Yes, they were. / No, they weren’t. you were Were you in bed at that time? Yes, I was. / No, I wasn’t. (2)实义动词(如 help/collect/plant)的过去式 · 规则变化: · 一般动词 + ed:help → helped,plant → planted · 以 e 结尾 + d:like → liked · 辅音字母 + y 结尾:变 y 为 i + ed:study → studied · 重读闭音节双写尾字母 + ed:stop → stopped · 不规则变化(本单元高频):do → did,dig → dug,grow → grew,sweep → swept,cut → cut,have → had,enjoy → enjoyed 句型 结构 例句 一般疑问句 Did + 主语 + 动词原形 + ...? Did you help out at the community center? 肯定 / 否定回答 Yes, 主语 + did. / No, 主语 + didn’t. Yes, I did. / No, I didn’t. 特殊疑问句 疑问词 + did + 主语 + 动词原形 + ...? Who did they help? They helped Uncle Zhang. 二、中考高频考点 1. be 动词与实义动词过去式的句型区分 · be 动词过去式:疑问句直接把 was/were 提前,否定句直接加 not。 · 实义动词过去式:疑问句 / 否定句必须用助动词 did/didn’t,后面动词变回原形(中考高频陷阱!)。 例:错误:Did you helped others? 正确:Did you help others? 2. 不规则动词过去式(本单元重点词) do-did, dig-dug, grow-grew, sweep-swept, cut-cut, have-had 是中考完形、写作的高频词,必须牢记。 3. 过去式时间状语的识别 last weekend/ yesterday/ just now/ at that time 等是判断一般过去时的标志,看到这些词必须用过去式。 4. 一般过去时的回答一致性 · 用 Was/Were 提问,回答必须用 was/wasn’t / were/weren’t。 · 用 Did 提问,回答必须用 did/didn’t,不能用 was/were。 三、易错点 & 易混点 易错类型 错误示例 正确形式 原因分析 1. did 后动词忘变回原形 Did you helped out at the center? Did you help out at the center? did 是助动词,后面必须接动词原形 2. was/were 与人称不匹配 Were he at home yesterday? Was he at home yesterday? 单数用 was,复数用 were 3. 回答前后不一致 Was he there? Yes, he were. Was he there? Yes, he was. 回答的 be 动词要和问句主语一致 4. 不规则动词拼写错误 He digged a hole. He dug a hole. dig 的过去式是 dug,不是 digged 5. 时间状语与时态不匹配 I help the old man yesterday. I helped the old man yesterday. yesterday 表示过去,要用过去式 四、实用记忆口诀 口诀 1:be 动词过去式 我(I)用 was,你(you)用 were, is 变 was,are 变 were, 单数 was,复数 were, 否定句后加 n’t,疑问 was/were 提句前。 口诀 2:实义动词过去式 过去式,很简单, 规则加 ed,不规则要记牢; 否定疑问加 did,动词原形要记好, 时间状语是信号,过去动作别忘掉。 五、本单元核心句型 1. —How was your volunteer activity last weekend? —It was great! We collected some money for wild animals. 2. —Did you take part in other activities? —Yes, we did. We planted some trees in the community. 3. Was he/she in Shanghai yesterday? Yes, he/she was. / No, he/she wasn’t. 4. Were they at home just now? Yes, they were. / No, they weren’t. 5. Did you help out at the community center? Yes, I did. / No, I didn’t. 6. Who did they help? They helped Uncle Zhang. 六、单元 chant 核心动词过去式汇总 1. We all did volunteer work at the community garden. 2. We grew lovely vegetables and beautiful flowers. 3. We dug, swept and we planted. 4. We watered, cut out the bad plants, and then we waited. 5. We had fun working together. 6. We enjoyed helping each other. 【同步语法练习】 一、按要求改写句子(每空一词) 1.
