Unit 8 I can do this for you 单元句型专项-2026-2027学年上学期英语三年级上册（译林版三起•新教材） 第一部分 单元句型核心精讲（专项重点梳理） 一、课文必背核心句型（Story time + Cartoon time 全部交际句） 1. 表达自己能做什么（can 肯定句核心句型） - I can sing. 译：我会唱歌。 要点：can 后面接动词原形 - I can sing too. 译：我也会唱歌。 要点：too 表示"也"，放在句末 - I can dance. 译：我会跳舞。 - I can draw. 译：我会画画。 - I can take pictures. 译：我会拍照。 - We can clean the table. 译：我们会擦桌子。 要点：we 我们，后面也用 can + 动词原形 2. 为他人做事（can ... for ... 核心句型） - I can sing a song for you. 译：我能为你唱首歌。 要点：for you 为你 - I can draw a picture for you. 译：我能为你画一幅画。 - I can dance for you, Grandpa. 译：爷爷，我能为你跳舞。 - I can do things for my family. 译：我能为我的家人做事。 要点：for my family 为我的家人 3. 夸赞与回应交际句型 - Great! 译：太棒了！ - How lovely! 译：真可爱！ - Thank you, Bobby. I love you. 译：谢谢你，博比。我爱你。 - I love you too, Grandpa. 译：爷爷，我也爱你。 4. 关心与询问句型 - Are you OK, Bobby? 译：博比，你还好吗？ - Oh, I'm dizzy... 译：哦，我头晕…… - What can you do for your family? 译：你能为你的家人做什么？ 5. 一般疑问句与回答 - Is this a fox? 译：这是一只狐狸吗？ - No, it's you! 译：不，是你！ - Ha ha! 译：哈哈！ 二、句型高频语法考点（专项突破易错点） 1. 情态动词 can 的用法（本单元核心语法） 句型结构 用法 例句 主语 + can + 动词原形 表达 "能 / 会做某事" I can sing. 主语 + can + 动词 + too 表达 "也能 / 也会" I can sing too. 主语 + can + 动词 + for + 人 表达 "为某人做某事" I can draw for you. Can + 主语 + 动词原形？ 一般疑问句 "能…… 吗？" Can you sing? Yes, 主语 + can. / No, 主语 + can't. 肯定 / 否定回答 Yes, I can. / No, I can't. 2. can 的重要特点 - can 后面必须接动词原形，不能加 -ing 或 -s。 错误：I can singing. 正确：I can sing. 错误：He can sings. 正确：He can sing. - can 没有人称变化，所有人称都用 can。 例：I can / You can / He can / She can / We can / They can - can 的否定形式是 can't（= cannot）。 例：I can't dance.（我不会跳舞。） 3. too 的用法 - too 表示"也"，放在句末，前面用逗号隔开（口语中可省略逗号）。 例：I can sing. I can dance too. - 区别：too 用于肯定句末；either 用于否定句末（三年级不要求掌握 either，了解即可）。 4. for 的用法 - for + 人，表示"为了某人/给某人"。 例：for you（为你）、for my family（为我的家人）、for Grandpa（为爷爷） 5. 重点易错点 - can 后面动词用原形，不要加 s 或 ing。 错误：She can dances. 正确：She can dance. - 表达"我也会"用 I can ... too，不用 I too can ...。 错误：I too can sing. 正确：I can sing too. - take pictures 是固定搭配"拍照"，picture 用复数。 错误：take picture 正确：take pictures - clean the table 是固定搭配"擦桌子"，不要漏掉 the。 错误：clean table 正确：clean the table 6. 核心固定搭配 短语 中文 sing a song 唱一首歌 draw a picture 画一幅画 take pictures 拍照 clean the table 擦桌子 do things for my family 为我的家人做事 New Year's Day 元旦 Are you OK? 你还好吗？ I'm dizzy. 我头晕。 I love you. 我爱你。 How lovely! 真可爱！ 三、单元句型问答模板（背诵模板，用于仿写） 1. 表达自己的能力 A: What can you do? B: I can sing. 2. 表达"我也会" A: I can dance. B: I can dance too. 3. 为家人做事 A: What can you do for your family? B: I can clean the table for my family. 4. 询问能力（一般疑问句） A: Can you draw?
