人教版（2024）七年级上册英语 · 语法知识精讲与配套练习 · Starter Unit 3 Welcome! Starter Unit 3 Welcome! 本单元语法焦点：指示代词 this/that/these/those + 基数词 + 名词作定语 语法知识详解 一、指示代词 指示代词 含义 be动词 指代 回答用 this 这个（近处单数） is 单数名词 it that 那个（远处单数） is 单数名词 it these 这些（近处复数） are 复数名词 they those 那些（远处复数） are 复数名词 they 核心用法： ① this/that + is + 单数名词：This is a cat. That is a dog. ② these/those + are + 复数名词：These are apples. Those are oranges. ③ 回答this/that问句用it；回答these/those问句用they — What's this/that? — It's a pen. — What are these/those? — They're books. ④ 介绍某人时用 This is...（不用 He is...）：This is my teacher, Mr. Chen. ⑤ 打电话时：This is Mary. Who's that?（我是玛丽。你是谁？） 易错点： • this/that/these/those 不能与 a/an/the 或形容词性物主代词同时修饰名词 （× this my book → √ my book / √ this book） 二、基数词（0-100） 基数词表示数目多少。重点掌握以下规律： 范围 构成规则 例词 0-12 单独记忆 zero, one, two... twelve 13-19 基数词 + -teen thirteen, fourteen... nineteen 20-90（整十） 基数词 + -ty twenty, thirty... ninety 21-99 整十 + - + 个位 twenty-one, thirty-two 100 one hundred one hundred 特殊拼写注意： • twelve（不是twoteen）, twenty（不是twoty） • thirteen, fifteen（不是threeteen, fiveteen） • forty（不是fourty）, eighty（不是eightty） • hundred 前接具体数字时不加s：two hundred（× two hundreds） 三、名词作定语 名词可以修饰另一个名词，构成复合名词短语。修饰语用单数形式： • carrot plant → carrot plants（胡萝卜植株） • apple tree → apple trees（苹果树） • tomato plant → tomato plants（西红柿植株） • shoe store（鞋店）, book shop（书店） 注意：表示人的职业时，man/woman要随中心词单复数变化： • a man teacher → two men teachers • a woman doctor → three women doctors 四、中考高频考点 ① this is 不可缩写（× this's），that is 可缩写为 that's ② 指示代词单复数转换：This is → These are; That is → Those are ③ How many + 复数名词? 询问数量：How many ducks are there? ④ What color + be + 主语? 复数主语用are：What color are they? 配套练习题 单项选择（10题，每题1分，共10分） 1. — What's ______ over there? — ______ a cat.
