Unit 5 语法讲练 2026-2027学年人教版英语七年级上册

Unit 5语法精讲精练 情态动词 can(表能力) 一、核心知识点:情态动词 can 1. 基本含义 can 表示能够、会(具备某种能力),无人称和数的变化,所有人称后面都只用原形 can。 否定形式:can not = can’t(不会、不能) 2. 关键规则(3a 重点) can /can’t 后面必须加动词原形,无论主语是 I/he/they,动词永远不变形。 例句: Can you play ping-pong?(play 原形,不加 s) Emma can sing well.(sing 原形) She can’t play instruments.(play 原形) 3. 四种基础句式 (1)肯定句 主语 + can + 动词原形 I can run fast. She can play the violin. (2)否定句 主语 + can’t + 动词原形 I can’t swim. He can’t play chess. (3)一般疑问句 Can + 主语 + 动词原形? 简答只用 can /can’t,不用其他动词 —Can he play the violin? —Yes, he can. / No, he can’t. (4)转折句(搭配 but) 前半句有能力,后半句无能力,形成对比 I can run fast, but I can’t swim. 4. 固定搭配小要点 play + 球类(无 the):play ping-pong, play chess play + 乐器(加 the):play the violin 二、易混易错提醒 he/she/it 后面不加 s can 后面只能动词原形: 3、 对比表格 句式结构 例句 肯定 They can swim. 否定 They can’t fly. 疑问 Can they climb trees? 简答 Yes, they can. / No, they can’t. 专项分层训练 专项一 3a 观察识别 划出所有 can /can’t 后面的动词,全部为原形,无变形 Can you play ping-pong?
