新人教版七年级上册英语 Unit 2 We‘re Family! 语法精讲与专项练习 📚 语法精讲部分 第一板块：名词所有格——“……的”的表达 1.1 什么是名词所有格 在英语中，当我们想表达“某人的某物”或“某物的某物”时，要用名词所有格。它的核心含义就是“……的”。 思维导图：名词所有格分类 名词所有格 │ ┌───────────────┼───────────────┐ │ │ │ ’s所有格 of所有格 双重所有格 (有生命的人/物) (无生命的事物) (of + ’s所有格) 1.2 ’s所有格（有生命的名词） ① 单数名词：名词 + ’s 规则 例句 含义 单数名词末尾直接加’s Teng Fei‘s grandfather 腾飞的爷爷 人名末尾加’s Peter‘s bag 彼得的包 不定代词后加’s somebody‘s book 某人的书 例句： · This is my mother’s piano. 这是我妈妈的钢琴。 · Peter‘s father is a teacher. 彼得的爸爸是老师。 ② 复数名词：分两种情况 情况 规则 例句 含义 复数以-s结尾 直接加 ’ grandparents‘ house 祖父母的房子 复数不规则变化 加 ’s children‘s books 儿童书籍 例句： · My grandparents’ house is big. 我祖父母的房子很大。 · Children‘s Day is on June 1st. 儿童节在6月1日。 ③ 共同拥有 vs 各自拥有（高频考点） 类型 结构 例句 含义 共同拥有 A and B’s + 单数名词 Mary and Gina‘s house 玛丽和吉娜（共有的）房子 各自拥有 A’s and B‘s + 复数名词 Mary’s and Gina‘s houses 玛丽的房子和吉娜的房子（各自拥有） ⚠️ 判断技巧： 如果两人共同拥有一件物品，只在最后一个人名加’s；如果各自拥有，每个人名都加’s，且名词用复数。 1.3 of所有格（无生命的名词） 结构：the + 名词 + of + 名词 例句 含义 a photo of my family 我的一张全家福 the name of the book 这本书的名字 the window of the room 房间的窗户 1.4 双重所有格 结构：a/an/this/that + 名词 + of + 名词’s 例句 含义 a friend of my father‘s 我爸爸的一个朋友 this book of Tom’s 汤姆的这本书 ⚠️ 与普通所有格的区别： “a friend of my father‘s”强调“我爸爸众多朋友中的一个”，而“my father’s friend”强调“我爸爸的那个朋友”。 第二板块：形容词性物主代词 vs 名词性物主代词 2.1 物主代词家族全览 人称 形容词性物主代词（+名词） 名词性物主代词（单独使用） 第一人称单数 my 我的 mine 我的 第二人称单数 your 你的 yours 你的 第三人称单数 his 他的 his 他的 第三人称单数 her 她的 hers 她的 第三人称单数 its 它的 its 它的 第一人称复数 our 我们的 ours 我们的 第二人称复数 your 你们的 yours 你们的 第三人称复数 their 他们的 theirs 他们的 2.2 核心区分规则 🔑 形容词性物主代词 = “形容词” ，后面必须跟名词！ 🔑 名词性物主代词 = “名词” ，可以单独使用！ 转换公式：形容词性物主代词 + 名词 = 名词性物主代词 形容词性物主代词（修饰名词） 名词性物主代词（独立使用） This is my book. This book is mine. That is her pen. That pen is hers. These are their bags. These bags are theirs. 对比练习： 例句 用法 解析 This is my piano. ✅ 形容词性 修饰名词piano，不能单独使用 This piano is mine. ✅ 名词性 单独使用，后面无名詞 His name is Tom. ✅ 形容词性 修饰名词name That bag is his. ✅ 名词性 单独使用 第三板块：实义动词的一般现在时（第三人称单数） 3.1 什么是“第三人称单数” 适用主语： · 人称代词： he, she, it · 单数名词： my father, Tom, the cat · 不定代词： everyone, somebody 3.2 动词第三人称单数的变化规则 情况 规则 例词 一般情况 直接加 -s work → works, play → plays 以 s, x, ch, sh, o 结尾 加 -es watch → watches, go → goes 辅音字母 + y 结尾 变 y 为 i，再加 -es study → studies, carry → carries 特殊情况 have → has have → has ⚠️ 注意： 如果是“元音字母 + y”结尾，直接加 -s，如：play → plays, say → says。 3.3 一般现在时三种句式结构 ① 肯定句 主语类型 结构 例句 I / You / We / They 动词原形 I like apples. He / She / It / 单数名词 动词三单 She likes apples. ② 否定句（借助助动词 do/does） 主语类型 结构 例句 I / You / We / They do not (don‘t) + 动词原形 They don’t like coffee.
