Unit 3 知识点1 Section A 2025-2026学年人教版七年级英语下册

七年级英语下册Unit3知识点1-Section A 一、核心内容梳理 本课时围绕 “体育运动与锻炼频率” 展开，核心目标是： 1. 掌握球类、运动器材类词汇； 2. 学会用how often询问动作频率，并用hardly ever、once or twice a week等短语回答； 3. 掌握物主代词（名词性 / 形容词性）的辨析与运用。 二、重点句型解析 （一）频率询问与回答类 1. —How often do you play ping-pong? —I play it three times a week. 解析：How often 用于询问动作发生的频率，答句需用频率副词或次数表达； three times a week 是 “次数 + 时间单位” 的固定结构，time 表 “次数” 时为可数名词。 例句：—How often do you run? —I run twice a day. 2. Han Lin hardly ever does exercise. 解析：hardly ever 是频率副词短语，意为 “几乎从不”，语气比hardly 更强，常用于一般现在时；do exercise 是固定搭配，意为 “做运动 / 锻炼”。 例句：She hardly ever eats junk food. 3. Peter plays basketball once or twice at weekends. 解析：once or twice 意为 “一两次”，at weekends 表示 “在周末”（英式表达，美式为on weekends）；主语是第三人称单数，谓语动词play 变plays。 例句：My brother watches TV once or twice a week. （二）物主代词与归属询问类 1. —Is this ping-pong bat yours? —No, it isn't mine. 解析：yours 是名词性物主代词，相当于your ping-pong bat，单独使用； mine 是名词性物主代词，相当于my ping-pong bat。 例句：—Is this pen his? —Yes, it's his. 2. No, hers is new. 解析：hers 是名词性物主代词，对应女性，相当于her tennis racket，在句中作主语；名词性物主代词后不加名词。 例句：My bag is blue. Hers is red. 3. Maybe it's Yaming's. 解析：Yaming's 是名词所有格，意为 “亚明的（东西）”，用于表示归属； maybe 是副词，意为 “也许”，放句首修饰整个句子。 例句：Maybe it's Li Tao's basketball. （三）运动相关表达类 1. I seldom do it, but I often play badminton. 解析：seldom 是频率副词，意为 “很少”，常用于一般现在时，位置在实义动词之前； play + 球类运动 时，球类前不加冠词。 例句：He seldom plays football, but he often plays basketball. 三、固定搭配与核心词汇 （一）运动器材与运动类词汇 词汇 中文释义 词汇 中文释义 baseball 棒球 baseball glove 棒球手套 basketball 篮球 exercise mat 瑜伽垫 / 运动垫 jump rope 跳绳 ping-pong bat 乒乓球拍 running shoes 跑鞋 tennis racket 网球拍 do exercise 做运动 play badminton 打羽毛球 play doubles 打双打 play ping-pong 打乒乓球 （二）频率表达与物主代词 类别 短语 / 词汇 用法说明 频率副词（短语） hardly ever 几乎从不 seldom 很少 once or twice 一两次 three times a week 一周三次 物主代词 形容词性：my/your/his/her/our/their 后必须加名词，如：your bat 名词性：mine/yours/his/hers/ours/theirs 后不加名词，单独使用 其他固定搭配 at weekends 在周末 practice makes perfect 熟能生巧（谚语） play as a team 团队协作 四、知识点挖空练习 （一）词汇与短语填空 1.
