Unit 4 This is my friend 班级 ____________ 姓名 ____________ 等第 ____________ 核心语法归纳 核心语法一：日常问候与告别交际用语 概念：不同时段的问候语（Good morning/afternoon）、初次见面问候（Nice to meet you）及告别语（Goodbye/bye），句首单词首字母需大写。 核心语法二：人称代词主格（I/you/he/she/it）的用法 概念：作句子主语，指代人或事物；I 表“我”，you 表“你/你们”，he 表“他”，she 表“她”，it 表“它”（指代动物或物品）。 核心语法三：be动词（am/is/are）的基础搭配规则 概念：I 搭配 am，you 搭配 are，he/she/it/单数名词搭配 is；否定式直接在后面加 not（am not/is not/are not）。 核心语法四：指示代词 this/that 的用法 概念：this 指代近处的人或物，that 指代远处的人或物；后接单数名词，搭配 be 动词 is。 核心语法五：不定冠词 a/an 的用法区别 概念：a 用于辅音音素开头的单数名词前，an 用于元音音素开头的单数名词前；表泛指“一个”。 核心语法六：一般疑问句（be动词引导）的用法 概念：将 be 动词（am/is/are）提至句首，句末加问号；肯定回答用 Yes，否定回答用 No。 核心语法七：介绍人物的句型（This is...） 概念：用于向他人介绍身边的人，后接人名或称谓，是三年级重点交际句型。 核心语法八：可数名词单数的基础运用 概念：表示单个的人或事物，可搭配 a/an 或指示代词 this/that 使用。 针对性练习 核心语法一：日常问候与告别交际用语 题型一 情景选择 ( ) 1. 早上见到老师，你应该说：______ A.
