一、核心定义
系动词（Linking Verb） 本身无完整词义，不能独立作谓语，需后接表语（名词、形容词、介词短语等）构成系表结构，用来说明主语的身份、性质、状态或特征。
二、分类及常见示例
系动词可分为三大类，其中感官系动词和变化系动词是初高中英语考试的高频考点。
1. 状态系动词
表示主语的状态或身份，最核心的是 be动词（am, is, are, was, were, been, being），用法最基础且广泛。
例句：She is a teacher.（表身份）/ The cake tastes delicious.（此处tastes为感官系动词，表性质）
补充：少数状态系动词如 keep （保持）、 stay （维持），也可归为状态类，例：He keeps silent in class.
2. 感官系动词
表示主语给人的感官感受，后接形容词作表语（注意：不能接副词）。
常见词汇：look（看起来）、sound（听起来）、smell（闻起来）、taste（尝起来）、feel（摸起来/感觉）
例句：The music sounds wonderful.（✅ 用形容词wonderful）
易错点：❌ The cloth feels softly. → ✅ The cloth feels soft.
3. 变化系动词
表示主语发生的状态、性质变化，后接形容词或名词作表语。
常见词汇：become（成为）、get（变得）、turn（变成，多指性质/颜色变化）、grow（渐渐变得）、go（变得，多指坏的变化）
例句：The leaves turn yellow in autumn. / The milk goes bad in hot weather.
三、核心易错点辨析
1. 系动词与实义动词的区别
系动词后接表语，实义动词（及物/不及物）后接宾语或状语。
例：He looks happy.（系动词+表语）/ He looks at me happily.（实义动词+宾语+状语）
系动词的否定和疑问需借助助动词，与实义动词规则一致。
例：Does she look tired? / The food doesn’t smell good.
2. 易混系动词的用法差异
become / get / turn ： become 可接名词/形容词，正式通用； get 多用于口语，接形容词； turn 接形容词时多指明显变化，接名词时不加冠词（例：He turned teacher later.）
go / turn ： go 多表负面变化（go bad/wrong）， turn 可表中性或正面变化（turn green）。
3. 不能用于进行时的系动词
状态系动词、感官系动词、变化系动词一般不用于进行时，避免语义矛盾。
❌ She is being a student.（错误，身份状态不表进行）
✅ She is a student.
一、单项选择
1．—_________ your shoes under the bed?
—Yes, they are.
A．Is B．Does C．Do D．Are
【答案】D
【详解】句意：——你的鞋子在床下吗？——是的，它们在床下。
考查be动词辨析。Is 是，单数；Does助动词，用于第三人称单数；Do助动词，用于第一、第二人称或复数；Are是，复数。根据答句“Yes, they are.”，可知问句询问复数主语“your shoes”的位置，需用be动词的复数形式Are。故选D。
2．—The silk scarf looks nice.
—Oh, that’s because it ________ soft and comfortable.
A．feels B．tastes C．smells D．sounds
【答案】A
【详解】句意：——这条丝巾看起来不错。——哦，那是因为它摸起来柔软舒适。
考查感官动词辨析。feels感觉（触觉）；tastes尝起来；smells闻起来；sounds听起来。根据“—The silk scarf looks nice. — Oh, that’s because it ... soft and comfortable.”可知，丝巾的质地是通过触觉感知的，而非味觉、嗅觉或听觉。故选A。
3．—Daniel, try this strawberry cake.
—It ________ delicious. I’d like to have some more.
A．smells B．feels C．tastes
【答案】C
【详解】句意：——丹尼尔，尝尝这个草莓蛋糕。——味道很棒，我想再吃点。
考查动词辨析。smells闻起来；feels摸起来；tastes尝起来。根据“It ... delicious. I’d like to have some more.”可知，此处指蛋糕尝起来美味。故选C。
4．Tom ______ his mother, and his mother ______ very young.
A．looks like; look B．looks like; looks C．looks; looks like
【答案】B
【详解】句意：汤姆看起来像他的母亲，他的母亲看起来非常年轻。
考查动词和动词短语。looks like看起来像，动词短语；look看起来，连系动词。第一空，空格后为“his mother”，需用looks like表示“看起来像他母亲”；第二空，空格后为“very young”，需用looks作为连系动词表示“看起来很年轻”；主语均为第三人称单数，谓语动词需用三单形式。故选B。
5．—They raise the flag in the large field.
—That ________ fun.
A．sound B．is sound C．sounds
【答案】C
【详解】句意：——他们在大场地上升旗。——听起来很有趣。
考查主谓一致和系动词用法。sound听起来，动词原形；is sound是声音，其中sound为名词；sounds听起来，第三人称单数。根据主语“That”可知，其为第三人称单数，谓语动词需用第三人称单数，sound作系动词，后接形容词fun，表示“听起来有趣”。故选C。
6．The milk ________ sour. You’d better not drink it.
A．tastes B．feels C．smells D．sounds
【答案】C
【详解】句意：牛奶闻起来酸了。你最好不要喝它。
考查动词辨析。tastes尝起来；feels感觉；smells闻起来；sounds听起来。根据语境可知，牛奶变质时通常会散发酸味，通过气味即可判断是否变质，无需品尝，因此用“smells”更符合逻辑。后半句“不要喝”也暗示无需尝即可确定变质。故选C。
7．The soup ________ good. Can you tell me how to make it?
A．tastes B．smells C．sounds D．feels
【答案】A
【详解】句意：这汤尝起来很好喝。你能告诉我怎么做吗？
考查动词辨析。tastes尝起来；smells闻起来；sounds听起来；feels感觉。由“Can you tell me how to make it?”可知，此处指汤尝起来很好喝，想询问怎么做，故选A。
8．This week, the weather ________ to change every day: One day is hot, while the next is cold.
A．seems B．looks C．sounds D．feels
【答案】A
【详解】句意：这周，天气似乎每天都在变化：一天热，第二天就冷。
考查动词辨析。seems似乎；looks看起来；sounds听起来；feels摸起来，感觉起来。根据下文“One day is hot, while the next is cold.”可知，一天热，第二天就冷，所以此处是指天气似乎在变化；考查seem to do sth.“似乎做某事”，固定搭配。故选A。
9．The boy’s face ________ red when he talks to someone.
A．goes B．gets C．turns D．grows
【答案】C
【详解】句意：当这个男孩和别人说话时，他的脸就会变红。
考查系动词辨析。goes变得，常修饰情况由好变坏或由正常便特殊；gets变得，强调变化过程的完成；turn变得，强调明显且彻底的变化，尤其是颜色或情绪；grows变得，侧重逐渐变化的过程。结合语境及“…red”可知，这个男孩的脸“变红”了，应用turn与之搭配，“turn red”表示“变红”，故选C。
10．—There are a lot of dark clouds in the sky and the wind is blowing strongly.
—It ________ that a heavy rain is coming.
A．feels B．sounds C．seems
【答案】C
【详解】句意：——天空中乌云密布，风刮得很大。——似乎要下大雨了。
考查动词辨析。feels感觉；sounds听起来；seems似乎。结合固定搭配“It seems that...看起来，似乎”可知，该空要填“seems”。故选C。
11．He doesn’t ________ to have many friends.
A．look B．seems C．seem D．look like
【答案】C
【详解】句意：他好像没有很多朋友。
考查系动词seem的用法。根据seem to do sth“似乎做某事”可知，此空填seem；一般现在时的否定句，借助了助动词doesn’t，后面的动词用动词原形。故选C。
12．—________ Lucy good at volleyball?
—No. She ________ play volleyball well.
A．Does; doesn’t B．Does; isn’t C．Is; doesn’t D．Is; isn’t
【答案】C
【详解】句意：——露西擅长排球吗？——没有。她排球打得不好。
考查系动词和助动词。短语“be good at”意为“擅长……”，又因为主语“Lucy”为第三人称单数，所以第一空用is；第二空后“play”为动词所以其前要加助动词，根据语境可知为否定，所以第二空填doesn’t。故选C。
13．Vegetables ________ good for your health.
A．be B．am C．is D．are
【答案】D
【详解】句意：蔬菜对你的健康有益。
考查be动词的用法。be是be动词的原形；am用于第一人称单数I后；is用于第三人称单数或不可数名词后；are用于第二人称单复数、第一/三人称复数或可数名词复数后。根据主语“Vegetables”可知，主语是可数名词复数，此处be动词应用are。故选D。
14．My pencils ________ black.
A．am B．is C．are D．be
【答案】C
【详解】句意：我的铅笔是黑色的。
考查主谓一致。am是，用于第一人称单数；is是，用于第三人称单数；are是，用于复数；be是，原形。主语“My pencils”为复数名词，表示多支铅笔，因此系动词用复数形式are。故选C。
15．Look! The chicken ________ on the table and the pears ________ in the bag.
A．is; is B．is; are C．are; is
【答案】B
【详解】句意：看！鸡肉在桌子上，梨在袋子里。
考查主谓一致。chicken作“鸡肉”讲时是不可数名词，作主语时谓语动词用单数；pears是复数名词，谓语动词用复数。故选B。
16．— Kate________ good at gardening. She works in her garden almost every day.
— Yes. But she ________ spend much time in her garden in winter because it is too cold.
A．does; isn’t B．does; doesn’t C．is; doesn’t D．is; isn’t
【答案】C
【详解】句意：——凯特擅长园艺。她几乎每天都在花园里工作。——是的。但是她在冬天不花太多时间在花园里，因为天气太冷。
考查be动词和助动词的用法。第一个空考查固定搭配“be good at”意为“擅长……”，主语Kate为第三人称单数，因此be动词用“is”；第二个空考查含有实义动词的否定句，“spend”意为“花费”，为实义动词，否定句需要借助于助动词，主语she为第三人称单数，故选择助动词does，否定形式为doesn't。故选C。
17．There ________ many electric buses running on the streets in China now.
A．is B．was C．are D．were
【答案】C
【详解】句意：现在中国有很多电动公交车在街道上行驶。
考查there be句型的时态。根据“now”可知，句子描述的是现在的状况，应用一般现在时；there be句型中，be动词的形式遵循“就近原则”，即由离其最近的主语决定，本句中离be动词最近的主语“many electric buses”是复数形式，所以be动词应用are。故选C。
18．The British boy ________ of medium height and ________ short straight hair.
A．has; has B．is; has C．is; is D．has; is
【答案】B
【详解】句意：这个英国男孩中等身高，并且有短直发。
考查动词辨析：has有；is是。第一个空描述身高，需用be动词“is”构成“be of medium height”，固定搭配，表示“中等身高”；第二个空描述拥有头发，需用实义动词“has”表示拥有。故选B。
19．—________ your father free on Sundays?
—No. He has to work at weekends.
A．Is B．Do C．Does D．Are
【答案】A
【详解】句意：——你父亲星期天有空吗？——不，他周末必须工作。
考查系动词的用法。根据“your father free on Sundays”可知缺少谓语动词，故用be动词而不是助动词；主语your father为单数，需用is。故选A。
20．May I have more chicken? It ________ so delicious.
A．feels B．touches C．tastes D．sounds
【答案】C
【详解】句意：我可以再要些鸡肉吗？它尝起来太美味了。
考查动词辨析。feel感觉；摸起来；touch触摸；taste尝起来；sound听起来。鸡肉是食物，用tastes表示尝起来美味。故选C。
二、完成句子
21．从远处看，那朵白云看起来像一大块棉花糖。
From a distance, the white cloud a big marshmallow.

22．吃了太多垃圾食品后，我觉得恶心，我想我需要去看医生。
I after eating too much junk food, and I think I need to see a doctor.
【答案】 feel sick
【详解】根据中英文对照，缺少“觉得恶心”，觉得“feel”，感官动词，其后面接形容词作表语，sick“恶心的，不适的”，形容词；该句时态为一般现在时，主语为I；故此处用动词原形feel。故填feel；sick。
23．打乒乓球使我们感觉很棒。
Playing table tennis .
【答案】 makes us feel great
【详解】根据中英文对照可知，此处缺少“使我们感觉很棒”。make sb. do sth“使某人做某事”；feel great“感觉很棒”。根据句子结构可知，动名词短语“Playing table tennis”作主语，视为第三人称单数，谓语动词需用三单形式。故填makes us；feel great。
24．这道菜看起来不错，味道甚至更好。
This dish and tastes even better.
【答案】looks good
【详解】look good“看起来不错”，结合“and tastes”可知，动词look也应用三单形式。故填looks good。
25．这饼尝起来很美味。我想再吃一块。
The cookie . I want to eat another one.
【答案】 tastes delicious
【详解】taste“尝起来”，感官动词，后接形容词delicious表示“美味的”，此句是一般现在时，主语是第三人称单数，动词用第三人称单数形式，故填tastes；delicious。
26．或许他们早上并不感觉饥饿。
Maybe they don’t in the morning.
【答案】 feel hungry

27．这个想法听起来不错，但实施起来可能很困难。
The idea good, but it might be difficult to carry out.
【答案】sounded
【详解】sound意为“听起来”，动词；句子描述的是一种客观感受，结合语境用一般过去时，此处用动词过去式sounded。故填sounded。

【答案】 soft drinks taste
【详解】soft drinks“软饮料”；taste“尝起来”，时态为一般现在时，主语是they，动词用原形。故填soft；drinks；taste。
29．这些桃子又大又红，味道很好。

10．句意：这样做的一个好方法是制定一周的菜单。根据“make...one-week menu”可知，此处表示制定一个一周的菜单，因此用不定冠词“a”修饰“one-week menu”。故填a。

一、核心定义
系动词（Linking Verb） 本身无完整词义，不能独立作谓语，需后接表语（名词、形容词、介词短语等）构成系表结构，用来说明主语的身份、性质、状态或特征。
二、分类及常见示例
系动词可分为三大类，其中感官系动词和变化系动词是初高中英语考试的高频考点。
1. 状态系动词
表示主语的状态或身份，最核心的是 be动词（am, is, are, was, were, been, being），用法最基础且广泛。
例句：She is a teacher.（表身份）/ The cake tastes delicious.（此处tastes为感官系动词，表性质）
补充：少数状态系动词如 keep （保持）、 stay （维持），也可归为状态类，例：He keeps silent in class.
2. 感官系动词
表示主语给人的感官感受，后接形容词作表语（注意：不能接副词）。
常见词汇：look（看起来）、sound（听起来）、smell（闻起来）、taste（尝起来）、feel（摸起来/感觉）
例句：The music sounds wonderful.（✅ 用形容词wonderful）
易错点：❌ The cloth feels softly. → ✅ The cloth feels soft.
3. 变化系动词
表示主语发生的状态、性质变化，后接形容词或名词作表语。
常见词汇：become（成为）、get（变得）、turn（变成，多指性质/颜色变化）、grow（渐渐变得）、go（变得，多指坏的变化）
例句：The leaves turn yellow in autumn. / The milk goes bad in hot weather.
三、核心易错点辨析
1. 系动词与实义动词的区别
系动词后接表语，实义动词（及物/不及物）后接宾语或状语。
例：He looks happy.（系动词+表语）/ He looks at me happily.（实义动词+宾语+状语）
系动词的否定和疑问需借助助动词，与实义动词规则一致。
例：Does she look tired? / The food doesn’t smell good.
2. 易混系动词的用法差异
become / get / turn ： become 可接名词/形容词，正式通用； get 多用于口语，接形容词； turn 接形容词时多指明显变化，接名词时不加冠词（例：He turned teacher later.）
go / turn ： go 多表负面变化（go bad/wrong）， turn 可表中性或正面变化（turn green）。
3. 不能用于进行时的系动词
状态系动词、感官系动词、变化系动词一般不用于进行时，避免语义矛盾。
❌ She is being a student.（错误，身份状态不表进行）
✅ She is a student.
