教学课件 北师大英语七年级下册 Unit5 语法专项——There was/were、一般过去时 全解精讲+分层练习 1 学习目标 掌握There was/were的核心用法与句式结构，能描述过去的存在 熟练运用一般过去时表达过去发生的动作和存在的状态 牢记动词过去式的规则变化，熟记高频不规则变化形式 能区分There be过去式和一般过去时的用法场景 运用所学完成单选、填空、句型转换、汉译英等题型 There was/were 核心含义 There was/were是There be句型的一般过去式形式 专门用于描述过去某个时间、某地存在或不存在的人或事物 侧重表达“过去有/没有”，区别于There is/are的现在存在含义 常搭配in the past、ten years ago、just now等过去时间状语 There was/were be动词搭配规则 be动词的选择由后面的名词单复数/类别决定，与现在时一致 后接单数名词或不可数名词，用was 后接复数名词，用were 无需考虑地点，仅以名词的数为判断依据，这是核心原则 There was/were 句式结构表 句式类型 基本结构 核心要点 肯定句 There was/were + 名词 + 地点 名词决定was/were，地点表位置 否定句 There wasn't/weren't + 名词 + 地点 was+not=wasn't，were+not=weren't 疑问句 Was/Were there + 名词 + 地点？ be动词提至句首，句末用问号 There was/were 肯定句用法 肯定句用于陈述过去某地有某物/某人，结构简单直接 名词为单数/不可数时用was，示例：There was a river near the village. 名词为复数时用were，示例：There were many trees in the park then. 时间状语可放在句首或句末，不改变句子核心结构 There was/were 否定句用法 否定句表达过去某地没有某物/某人，直接在be动词后加not was的否定是wasn't，were的否定是weren't，无其他变形 示例：There wasn't a hospital in this town ten years ago. 示例：There weren't any books on the desk just now. There was/were 疑问句及回答 疑问句将Was/Were提至句首，there紧跟其后，语序简单 单数/不可数名词用Was提问，复数用Were提问 肯定回答：Yes, there was/were. 否定回答：No, there wasn't/weren't. 示例：Was there a park here? — Yes, there was. 一般过去时 核心含义 一般过去时是描述过去的基础时态，应用范围极广 可表达过去某个时间发生的一次性动作，动作已结束 也可表达过去存在的状态或习惯性的动作 必须搭配过去时间状语，这是判断该时态的关键标志 一般过去时 常见时间状语 时间状语是一般过去时的“识别标签”，需熟记分类 单个时间：yesterday, yesterday morning/afternoon 段时间：last week/month/year, in 2000, in the past 其他：just now, a moment ago, at the age of 6 一般过去时 基本句式结构 肯定句：主语 + 动词过去式 + 其他，直接用过去式表动作 否定句：主语 + didn't + 动词原形 + 其他，借助didn't表否定 疑问句：Did + 主语 + 动词原形 + 其他？，借助Did提至句首 否定和疑问句中，动词必须恢复原形，这是高频考点 动词过去式 规则变化1 一般情况：直接在动词词尾加-ed，这是最基础的变化形式 清辅音后读/t/，例：work→worked, look→looked 浊辅音/元音后读/d/，例：play→played, live→lived 此类变化占比最高，只需直接加词尾，无需改变单词本身 动词过去式 规则变化2 以不发音的e结尾：直接加-d，省略重复的e，简化拼写 例：like→liked, dance→danced, use→used 以“辅音字母+y”结尾：变y为i，再加-ed 例：study→studied, carry→carried, worry→worried 动词过去式 规则变化3 重读闭音节结尾：双写末尾的辅音字母，再加-ed 判断标准：辅+元+辅结尾，且最后一个音节重读 例：stop→stopped, plan→planned, skip→skipped 初中阶段掌握常见的此类动词即可，无需过度拓展 动词过去式 高频不规则变化 不规则变化无固定规律，需单独记忆，是学习重点 高频词：go→went, see→saw, eat→ate, do→did, have→had, win→won tell→told, get→got, make→made 语法拓展 不规则动词过去式巧记 A-B-B型：have-had, get-got, make-made A-B-C型：go-went-gone, see-saw-seen, eat-ate-eaten 语法小练 单项选择 1.There ______ a big tree in front of our house last year.
