Unit 3 Food matters 语法讲解+每日一练- 2025-2026学年外研版英语七年级下册

Unit3 Food matters 连系动词 一、 连系动词的定义 连系动词（Linking Verb）本身有一定词义，但不能独立作谓语，必须和表语（形容词、名词、介词短语等）连用，构成“主语 + 连系动词 + 表语”的系表结构，用来说明主语的身份、特征、状态或性质。 二、 连系动词的分类及核心用法 1. 状态类连系动词 用来表示主语的身份、状态或特征，常见词有 be（am, is, are, was, were）。 · 用法：后可接名词、形容词、介词短语、数词等作表语。 · 例句： 1) She is a middle school student.（接名词，表身份） 2) The park was beautiful last spring.（接形容词，表特征） 3) My parents are at home now.（接介词短语，表状态） 2. 感官类连系动词 用来表示主语给人的感官感受，由感官动词转化而来，常见词有 look（看起来）、sound（听起来）、smell（闻起来）、taste（尝起来）、feel（摸起来/感觉）。 · 用法：后只能接形容词作表语，不能接副词。 · 例句： 1) The flowers smell sweet.（√） 2) The flowers smell sweetly.（×） 3) This sweater feels very soft. 3. 变化类连系动词 用来表示主语的状态或性质发生变化，常见词有 become（变得）、get（变得）、turn（变得，多指颜色/性质的自然变化）、grow（渐渐变得）、go（变得，多指向坏的方面变化）。 · 用法：后接形容词作表语。 · 例句： 1) The weather gets colder in autumn. 2) The leaves turn yellow when fall comes. 3) The milk goes bad in the hot sun. 4. 持续类连系动词 用来表示主语的状态持续不变，常见词有 keep（保持）、stay（保持）、remain（仍然是）。 · 用法：后接形容词作表语。 · 例句： 1) You should keep quiet in the library. 2) The door stays open all day. 三、 核心考点总结 1. 系表结构的判断 连系动词后接形容词作表语，而实义动词后接副词作状语。 例：The music sounds beautiful.（系动词+形容词） He plays the piano beautifully.（实义动词+副词） 2. 感官类连系动词的易错点 感官类连系动词（look, sound等）与对应的实义动词用法不同： · 作连系动词：后接形容词 → She looks happy. · 作实义动词：后接宾语 → She looks at me happily. 3. 变化类连系动词的辨析 turn 多接颜色词，强调自然变化 → The sky turns dark. go 多表示向坏的方向变化 → The food goes bad. become 强调状态的质变 → He becomes a teacher. 4. 主谓一致 连系动词的单复数形式由主语决定，与表语无关。 例：The book is interesting.（主语单数，用is） These books are interesting.（主语复数，用are） 四、 常见误区提醒 · 误区1：连系动词和实义动词混淆，误用副词修饰连系动词。 错误：He feels happily. 正确：He feels happy. · 误区2：将 get 等当作实义动词，忽略其连系动词用法。 例：It gets warm in spring.（get是连系动词，后接形容词warm） ( 第 1 页 共 4 页 ) 学科网（北京）股份有限公司 $ 七下英语语法每日一练 语法一日一练 （25年外研新版七年级下册英语） Unit1 一般过去时 Unit2 不定代词 · Unit3 连系动词 Unit4 祈使句 Unit5 比较级和最高级 Unit6 as...as句型 Unit3连系动词Day1 第一部分 单项选择 1. Each kind of porridge ______ great in its own way.
