Unit 6 Is he your grandpa? 单元语法专项-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 单元核心语法知识点总结 一、be动词 is 的一般疑问句（单元核心语法★★★） 1. 基本概念 用 Is 开头的一般疑问句，可以用来确认一个人的身份或关系，意为"他/她/它是……吗？"。本单元主要用来确认家庭成员关系。 2. 肯定句变一般疑问句 方法：把 be 动词 is 提到句子最前面，句末加问号。 - 肯定句：He is my grandpa. 他是我的爷爷。 - 一般疑问句：Is he your grandpa? 他是你的爷爷吗？ ⚠️ 注意：变疑问句时，my（我的）通常要变成 your（你的）。 3. 一般疑问句的回答 - 肯定回答：Yes, 主语 + is. - 否定回答：No, 主语 + isn't. （is not = isn't，isn't 是 is not 的缩写） 例：—Is he your father? 他是你的爸爸吗？ —Yes, he is. 是的，他是。 —No, he isn't. 不，他不是。 例：—Is she your mother? 她是你的妈妈吗？ —Yes, she is. 是的，她是。 —No, she isn't. 不，她不是。 4. 三种主语搭配 主语 指代 例句 he 男性（他） Is he your grandpa? she 女性（她） Is she your grandma? it 婴儿 / 性别不详（它） Is it your cousin? ⚠️ 重点：指代性别不明确的婴儿时，要用 it，不用 he 或 she。 例：Is it your baby cousin? 这是你的小表弟/表妹吗？ 二、who's 询问身份句型（单元重点语法★★） 1. 基本概念 who's = who is，意为"是谁"，用来询问一个人的身份。 2. 句型结构 Who's + 主语（he/she/it/this boy/that woman...）? 答语：He's/She's/It's + 身份（my grandpa/my aunt...） 例：—Who's he? 他是谁？ —He's my uncle. 他是我的叔叔。 例：—Who's that woman? 那个女人是谁？ —She's my aunt. 她是我的阿姨。 例：—Who's the baby? 这个婴儿是谁？ —It's my cousin. 这是我的表弟。 3. 常见缩写形式 完整形式 缩写形式 中文 who is who's 是谁 he is he's 他是 she is she's 她是 it is it's 它是 is not isn't 不是 三、单元语法高频考点&易错点总结 易错点 错误示例 正确用法 回答人称不一致 Is he your uncle? Yes, she is. 问句用 he，回答也用 he：Yes, he is. isn't 拼写错误 isnot / is'nt 正确缩写：isn't（i-s-n-'t） 婴儿指代误用 he/she Is he your baby cousin? 性别不详用 it：Is it your baby cousin? 疑问句中 my 不变 your Is he my father? 问对方时用 your：Is he your father? 肯定回答缩写错误 Yes, he's. 肯定回答中 is 不能缩写：Yes, he is. who's 与 whose 混淆 Whose he? 问 "是谁" 用 who's：Who's he? 四、单元语法问答背诵模板 1. 确认亲属身份 A: Is he your grandpa?
