Unit 4 This is my friend 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. 介绍他人的核心句型 - This is Sam. He's my friend. 译：这是萨姆。他是我的朋友。 要点：This is... 是近距离介绍他人的固定句型；he's = he is，用于指代男性。 - This is Zhang Hua. 译：这是张华。 - This is Su Hai. She's my friend. 译：这是苏海。她是我的朋友。 要点：she's = she is，用于指代女性。 - I have many friends in my class. 译：我在班里有很多朋友。 要点：many 后接可数名词复数形式。 2. 初次见面交际句型 - Nice to meet you. 译：很高兴认识你。 - Nice to meet you too. 译：我也很高兴认识你。 要点：too 表示“也”，通常放在句末。 3. 日常应答与交际句型 - Goodbye, Max and Willy! 译：再见，马克斯和威利！ - It's good! 译：太棒了！ 要点：it's = it is - Thank you. 译：谢谢你。 二、句型高频语法考点（专项突破易错点） 1. 指示代词 this的用法 - this 意为“这，这个”，用来指代距离较近的人或事物。 - 当面介绍他人时，必须用 This is + 人名 开头，不能直接用 He/She is... 作为首次介绍。 2. 人称代词 he 与she - he 指代男性，意为“他”；she 指代女性，意为“她”。 - he's = he is，she's = she is，后可接名词、形容词，用来描述人物身份或特征。 3. 重点易错点 - 首次介绍他人必须用 This is...，不能直接说 He is my friend. 错误：He is my friend Zhang Hua. 正确：This is Zhang Hua. He's my friend. - this is没有缩写形式，不能写成 this's。 - too 表示“也”时，要放在句子末尾。 4. 核心固定搭配 my friend 我的朋友 good friend 好朋友 Nice to meet you. 很高兴认识你 in my class 在我的班里 三、单元句型问答模板（背诵模板，用于仿写） 1. 同学间介绍新朋友 A: Hi, Liu Tao.
