Unit3 Food matters系动词讲解与练习 一、基本概念 系动词:本身有词义,但不能单独作谓语,后面必须接表语(说明主语身份、特征、状态),构成主系表结构:主语+系动词+表语 表语常由:形容词、名词、代词、介词短语 充当。 二、系动词分类（七下必考4大类） （一）be 动词（最基础,必掌握） am/is/ are /was/were 1.用法:单纯表示 **“是、存在”**，连接主语和表语 2.时态变化：一般现在时 am/is/are；一般过去时 was/were Milk is healthy food. 牛奶是健康食物。 They are hungry. 他们饿了。 The soup was hot just now. 这汤刚才很烫。 （二）感官系动词（本单元重中之重,高频考点） 表示五官感受,一共 5 个,口诀：一感二听三视闻 feel 感觉 /taste 尝起来 /smell 闻起来 /look 看起来 /sound 听起来 核心规则（必考） 1.后只能接形容词作表语，不能接副词（头号易错点） 2.有人称、时态变化（第三人称单数加 -s,过去式变形） 3.无被动语态,本身表被动含义 *taste 尝起来 The cake tastes sweet. 这个蛋糕尝起来很甜。 The noodles tasted delicious. 面条味道很不错。 ❌ taste deliciously（错误,不用副词） *smell 闻起来 The bread smells good. 面包闻起来很香。 *look 看起来 The salad looks fresh. 这份沙拉看起来很新鲜。 feel 摸起来；感觉（身体 / 事物触感） The food feels warm. 食物摸起来温热。 I feel full. 我感觉饱了。 sound 听起来 Your idea sounds great. 你的主意听起来很棒。 三单变形（单选常考） 主语为单数名词/不可数名词/he/she/it,动词加 s The juice tastes nice.（juice不可数,三单） （三）变化类系动词（表示 “变得”） 表示主语状态、身份发生变化，七下重点掌握 3 个：become /get/ turn 1.become 变得（侧重身份、状态长久变化） He becomes strong after exercising. 运动后他变得强壮了。 2.get 变得（侧重情绪、天气、身体渐变，常用比较级） Days get short in winter. 冬天白天变短了。I get hungry easily. 我很容易饿。 3.turn 变得（侧重颜色、性质改变）The leaves turn yellow. 树叶变黄。 （四）状态类系动词（表示 “保持、似乎”） 表示主语状态不变/似乎怎样/常考 2 个： keep 保持（状态）keep + 形容词 Keep healthy. 保持健康 Keep quiet. 保持安静 seem 似乎,好像seem + 形容词 The food seems terrible. 这食物看起来好像很难吃。 三、必考易错点（丢分重灾区） 易错 1：系动词后 + 形容词，严禁加副词（必考） ✅ The apple tastes sweet. ❌ The apple tastes sweetly. 易错 2：感官系动词无被动语态 这类词本身就表示 “被…… 起来”，不用 be done ✅ The food smells nice.❌ The food is smelt nice. 易错 3：区分 “系动词用法” 和 “实义动词用法”（高频辨析题） 同一个单词,两种词性,含义、用法完全不同： look o系动词：看起来 + 形容词You look tired. 你看起来很累。 o实义动词：看（动作）+ 介词 at + 宾语Look at me. 看着我。 feel o系动词：感觉、摸起来 + 形容词The cloth feels soft. 这块布摸起来很软。 o实义动词：触摸（动作）Don’t feel the hot pot. 别摸火锅。 taste o系动词：尝起来 + 形容词The soup tastes salty. 汤尝起来很咸。 o实义动词：品尝（动作）+ 宾语Taste the soup. 尝一下这碗汤。 易错 4：keep 固定搭配 keep + 形容词（系动词，保持…… 状态）keep healthy 保持健康 /keep warm 保暖 四、配套语法口诀（方便背诵） 系动词,分四类,be 动词排第一； 感官五词要记牢,闻尝看听和感觉到； 后面只把形容词加,副词上场就出错； 变化变得 become/get/turn;保持seem和 keep; 实义动词有动作,系动只把状态说。 【巩固练习】 一、用所给词的适当形式填空 1.The milk ______ (smell) bad.
