Hers is blue. 我的包是黑色的,她的(包)是蓝色的。(Hers = Her bag) - I don’t like my dress. I like yours. 我不喜欢我的裙子,我喜欢你的(裙子)。(yours = your dress) - The blue jacket is mine. 这件蓝色夹克是我的。(mine = my jacket) ⚠️ 易错警示(七年级必考) ① its vs it's its:物主代词,意为它的(无撇号)→ The cat washes its face. 小猫洗它的脸。 it's = it is 的缩写,意为它是 → It's a cat. 它是一只猫。 ② a friend of mine 我的一位朋友,of后要用名词性物主代词。 核心语法3:指示代词(this/that/these/those) 知识点1 核心语法讲解 指示代词用来指代人或事物,体现距离远近。 单词 含义 使用场景 单数 this 这 离说话人近的单数人/物 that 那 离说话人远的单数人/物 复数 these 这些 离说话人近的复数人/物 those 那些 离说话人远的复数人/物 知识点2 核心必考规则 1. 作主语时的主谓搭配 this / that + be动词 is;these / those + be动词 are - This is my pen, and that is yours. 这是我的钢笔,那是你的。 - These are our books. Those are their books. 这些是我们的书。那些是他们的书。 2. 用于介绍人、评价事情 - 介绍近处单个人:This is my sister Lucy. 这是我的妹妹露西。 - 介绍近处多个人:These are my parents. 这是我的父母。 - —Let’s play badminton! 我们去打羽毛球吧! —That’s a good idea. 那是个好主意。 3. 指示代词一般疑问句的回答(高频陷阱) ⚠️ 不能用this / that / these / those回答,要用it或者they替代。 - —Is this your pen? 这是你的钢笔吗? —Yes, it is. / No, it isn’t. - —Are those your books? 那些是你的书吗? —Yes, they are. / No, they aren’t. 4. 电话固定用语(仅限打电话场景,普通句子不适用) this指代自己,that指代对方 - Hello! This is Tina speaking. 你好!我是蒂娜。 - —Hello! Is that John? 你好!请问是约翰吗? —Yes, speaking. 是的,请讲。 ⚠️ 补充:that/those可以避免名词重复 The ruler is longer than that one. 这把尺子比那把长。 📌 课堂总结口诀 主格句首做主语,宾格动介后面立; 形物代词带名词,名物代词独立起; this近that远,these/those是复数; 问句this/that,回答要用it;问句these/those,回答要用they。 考点精练 一、单项选择(共30小题) 从A、B、C、D四个选项中,选出可以填入空白处的最佳选项。 ( )1.— _________ my baseball? — _________ under the chair.
