新七年级英语暑假衔接讲义 （人教2024版） ━━━━━━━━━━━━━━━━━━━━━━━━━ 第7讲 Unit 1 You and Me Part 1 — be动词与人称代词 适用年级：新七年级（小升初） 教材版本：人教2024版 内容说明：学习be动词am/is/are的用法、人称代词主格和自我介绍拓展 Part 1 知识讲解 一、人称代词主格 (Personal Pronouns) 人称代词用来代替人或事物。主格形式用作句子的主语。英语中的人称代词主格有： 人称 代词 中文 例句 第一人称单数 I 我 I am a student. 第二人称单数 you 你 You are my friend. 第三人称单数 he 他 He is tall. 第三人称单数 she 她 She is a teacher. 第三人称单数 it 它 It is a cat. 第一人称复数 we 我们 We are happy. 第二人称复数 you 你们 You are students. 第三人称复数 they 他们/她们/它们 They are in the classroom. 注意：you 既可以表示“你”，也可以表示“你们”，要根据上下文判断。 二、be动词 (am/is/are) 用法 be动词是英语中最基本的动词，意思是“是”。be动词有三种形式：am, is, are。它们的用法由主语的人称和数决定。 【记忆口诀】I用am，you用are，is连着他她它；单数is复数are。 主语 be动词 例句 I am I am a student. You are You are my friend. He / She / It is He is tall. / She is kind. / It is big. We are We are classmates. They are They are in the classroom. 三、自我介绍拓展 除了用“I'm + 名字”介绍自己，我们还可以用更多句型介绍自己的情况： 句型 例句 中文意思 I'm from... I'm from China. 我来自中国。 I'm ... years old. I'm 12 years old. 我12岁。 I'm in Class... I'm in Class 3, Grade 7. 我在七年级三班。 I'm a... I'm a student. 我是一名学生。 完整自我介绍示例： Hello! I'm Li Ming. I'm 12 years old. I'm from China. I'm a student. I'm in Class 3, Grade 7. Nice to meet you! 四、缩写形式 (Contractions) 在英语口语和非正式书面语中，主语和be动词常缩写在一起： 完整形式 缩写形式 I am I'm You are You're He is He's She is She's It is It's We are We're They are They're 注意：缩写形式中的撇号（'）不能省略。否定形式如“is not = isn't”，“are not = aren't”，“am not”一般没有标准缩写。 Part 2 典型例题 1. — How ______ you? — I ______ fine, thanks.
