Unit 5 She's my mother 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. 介绍家庭成员的核心句型 - This is my dad. 译：这是我的爸爸。 要点：This is 用于向他人介绍近处的人物，后接单数名词；my 表示“我的”，后面接名词 - This is my mother. 译：这是我的妈妈。 - Come and meet my family. 译：来见见我的家人。 要点：come and meet 来见见；family 家庭、家人 - This is my mum. She's great. 译：这是我的妈妈。她很棒。 要点：She's = She is；great 极好的、好棒的 2. 询问人物身份的句型 - Who's she? 译：她是谁？ 要点：Who's = Who is；she 指代女性 - Who's he? 译：他是谁？ 要点：he 指代男性 - She's my mum. 译：她是我的妈妈。 - He's my father. 译：他是我的爸爸。 3. 晚间问候交际句型 - Good evening. 译：晚上好。 要点：用于傍晚或晚上见面时的礼貌问候，答语也用 Good evening. - Hi, I'm Su Hai. 译：你好，我是苏海。 要点：用于初次见面时的自我介绍 二、句型高频语法考点（专项突破易错点） 1. be 动词的缩写形式（本单元核心语法） - Who's = Who is - She's = She is - He's = He is - 易错提醒：This is 没有缩写形式，不能写成 This's。 2. 人称代词 he / she 的用法 - he 用来指代男性（男子、男孩、雄性动物） - she 用来指代女性（女子、女孩、雌性动物） - 两者都属于第三人称单数，后面搭配 be 动词 is 例：He is my brother. / She is my sister. 3. 形容词性物主代词 my - 用在名词前面，表示“我的”，说明事物的归属 例：my family 我的家人；my dad 我的爸爸 4. 重点易错点 - 性别指代易错：男性用 he，女性用 she，不能混淆。 错误：He's my mother. 正确：She's my mother. - This is 不能缩写。 错误：This's my dad. 正确：This is my dad. - 回答 Who's he/she? 时，要用完整的 He's/She's... 句型。 5. 核心固定搭配 come and meet 来见见 my family 我的家人 Good evening. 晚上好 三、单元句型问答模板（背诵模板，用于仿写） 1. 介绍自己的家人 A: Come and meet my family.
