2026 高考高三英语二轮定语从句专题复习
一、高考核心知识点梳理
（一）定语从句两大核心类别（高考必考）
核心定义：定语从句是修饰名词或代词的从句，被修饰的词叫先行词，连接从句与主句的词叫
关系词。关系词分为关系代词和关系副词，在从句中充当一定成分。
1. 限定性定语从句
① 功能：对先行词进行修饰限定，与先行词关系紧密，去掉后主句语义不完整；从句前无逗
号。
② 关系代词：who（指人，作主语/宾语）、whom（指人，作宾语）、whose（指人/物，作定
语）、which（指物，作主语/宾语）、that（指人/物，作主语/宾语）
③ 关系副词：when（指时间，作状语）、where（指地点，作状语）、why（指原因，作状语，
先行词为reason）
④ 高考真题例句（2025·新课标I 卷改编）：The girl who won the English speech contest is
my deskmate.
2. 非限定性定语从句
① 功能：对先行词进行补充说明，与先行词关系松散，去掉后主句语义完整；从句前有逗号；
不可用that 引导，不可省略关系词。
② 关系代词：who/whom/whose/which（可指代整个主句内容）
③ 关系副词：when/where（why 不可引导）
④ 高考真题例句（2024·全国卷II 改编）：We visited the ancient temple, which was built in
the Tang Dynasty.
（二）定语从句三大高频考点变形（高考重难点）
1. 关系词的选择技巧
① 核心原则：一看先行词，二看关系词在从句中充当的成分
② 具体判定：
*从句缺主语/宾语→用关系代词who/whom/which/that
*从句缺定语→用whose
*从句缺状语（时间/地点/原因）→用关系副词when/where/why
③ 真题原型（2023·新课标卷I）：This is the factory where my father worked ten years ago.
（从句缺地点状语）
2. 只能用that 引导的四种情况
① 先行词为不定代词（everything, nothing, something 等）
② 先行词被序数词、最高级修饰
③ 先行词被the only, the very, the same 修饰
④ 先行词既有人又有物
⑤ 真题原型（2024·天津卷）：All that we need to do is to work hard and hold on to our
dreams.
3. 介词+关系代词的用法
① 结构：介词+which（指物）/whom（指人）
② 介词选择依据：取决于先行词的搭配或从句中动词的搭配
③ 真题原型（2025·浙江卷）：The man with whom my mother is talking is our head
teacher.（talk with sb. 固定搭配）
（三）定语从句的特殊考法（2025 模拟新增考点）
1. as 引导的定语从句
① 用法1：用于such...as..., the same...as...结构中，as 在从句中作主语或宾语，此时as 不可替
换为that
② 用法2：引导非限定性定语从句时，可置于句首、句中或句末，指代整个主句内容，意为
“正如”
③ 高考真题例句1（2024·新课标I 卷改编）：Such problems as are often mentioned by
teachers are not easy to solve.（as 引导限定性定语从句，在从句中作主语）
④ 高考真题例句2（2025·浙江卷改编）：As we expected, our team won the championship
finally.（as 引导非限定性定语从句，置于句首指代主句内容）
2. 分隔式定语从句
① 定义：先行词与定语从句之间被其他成分隔开
② 解题关键：需先跳过插入成分准确找到先行词，再判断关系词在从句中充当的成分
③ 高考真题例句1（2023·全国甲卷改编）：The only thing that we can do now is to wait
for the rescue team.（先行词thing 与定语从句之间被we can do now 隔开）
④ 高考真题例句2（2024·天津卷改编）：A new teacher will come tomorrow who will teach
us English literature.（先行词teacher 与定语从句之间被will come tomorrow 隔开）
二、 高考高频考点与易错点突破
（一）高频考点清单（近5 年考查频次）
1. 关系代词与关系副词的辨析：每年必考，涉及语法填空、短文改错题型
2. 限定性与非限定性定语从句的区别：每年必考，涉及语法填空、阅读理解题型
3. 介词
+ 关系代词的用法
：4 考，涉及语法填空、单选题型
4. 只能用
that
引导的特殊情况
：3 考，涉及语法填空、短文改错题型
（二）易错点辨析（丢分重灾区）
1. 关系代词that 与which 的区别
① 在限定性定语从句中，that 既可以指人也可以指物，which 只能指物；
② 非限定性定语从句中，只能用which 引导，绝对不能用that；
③ 当先行词为不定代词时，限定性定语从句只能用that 引导，不能用which；
④ 介词后面引导定语从句时，只能用which 指代物、用whom 指代人，不能用that。
2. 关系副词where/when 与关系代词which/that 的区别
① 判定关键：看从句中的谓语动词性质
② 具体规则：
*从句谓语动词是及物动词，后面缺少宾语→用关系代词which/that
*从句谓语动词是不及物动词，后面不缺宾语→用关系副词where/when
③ 正确例句：This is the park where we had a picnic last week.（had 为不及物动词，不缺
宾语）
④ 错误例句：This is the park which we had a picnic last week.
3. 定语从句与同位语从句的区别
① 同位语从句：解释说明先行词的具体内容，that 无词义，不充当从句中的任何成分
例句：The news that our team won the game excited everyone.
② 定语从句：修饰限定先行词，that 有指代意义，需要在从句中充当主语或宾语等成分
例句：The news that he told us excited everyone.（that 作told 的宾语）
三、 解题技巧（高考快速得分法）
（一）关系词判定三步法
1. 步骤：① 找出先行词；② 判断先行词指人/物/时间/地点；③ 分析关系词在从句中作主
语/宾语/定语/状语，从而确定关系词
2. 例句：先行词为the girl（指人），从句缺主语 → 用who/that；先行词为the park（指地
点），从句不缺宾语 → 用where
（二）非限定性定语从句判定技巧
1. 规则：从句前有逗号，指代事物用which，指代整个主句时，用which/as
2. 例句1：He missed the bus, which made him late for school.（which 指代前面整个主句）
3. 例句2：As is known to all, practice makes perfect.（as 置于句首指代主句）
（三）复杂定语从句判定技巧
1. 规则：遇到分隔式定语从句，先跳过插入成分定位先行词，再判断关系词在从句中充当的
成分
2. 例句：The letter that I received yesterday was from my pen pal.（插入成分为yesterday，
跳过定位先行词the letter，从句缺宾语用that）

定语从句专项学案 参考答案与详细解析
一、 语法填空（每题2 分，共20 分）
1. B 解析：改编自2024 新课标I 卷真题，先行词the path 指物，从句中缺少主语，且先行
词被介词短语along which 修饰，仍需用that/which 引导，此处选项中只有that 符合，考查限定
性定语从句关系词作主语的用法。
2. C 解析：对标2024 新课标II 卷真题，先行词Tang Xianzu 指人，非限定性定语从句中关
系词作主语，用who 引导，区别于作宾语时的whom，是高考常考的指人关系词辨析考点。
3. B 解析：基于2025 全国II 卷真题改编，先行词the countryside 指地点，从句中不缺主语
和宾语，bamboo and tea bushes grow wild 为完整主谓结构，需用where 作地点状语，考查关
系副词的判定。
4. D 解析：源自2025 北京卷真题，非限定性定语从句修饰先行词food waste（指物），从
句中作主语，只能用which 引导，考查非限定性定语从句的关系词选择禁忌（不可用that）。
5. A 解析：改编自2021 新高考II 卷真题，先行词companies 指物，从句中use 为谓语动词，
缺少主语，用which 引导，符合“先行词指物+从句缺主语”的高频考点模式。
6. B 解析：参考2023 全国甲卷真题，as 引导非限定性定语从句，指代整个主句内容，可置
于句中，意为“正如”，区别于which 不可置于句中作此类指代的用法，是高考特殊关系词考
点。
7. C 解析：依据2024 浙江1 月卷真题，先行词the way 作“方式”讲，从句中缺少主语，
需用that/which 引导，区别于作状语时的in which/that/省略结构，考查the way 作先行词的特
殊用法。
8. A 解析：结合2020 全国III 卷whose 用法考点，先行词The British Museum 与core
collection 为所有格关系，“博物馆的核心藏品”，用whose 作定语，考查whose 既指人也指物
的所有格用法。
9. B 解析：改编自2022 新高考I 卷真题，先行词the species 被all 修饰，限定性定语从句中
关系词作主语，只能用that 引导，不可用which，是高考定语从句的高频易错点。
10. C 解析：源自2025 浙江1 月卷真题，非限定性定语从句修饰先行词less formal clothing
（指物），从句中package 后缺少宾语，用which 引导，考查非限定性定语从句常规用法。

三、 单句改错（每题2 分，共20 分）

2. 去掉it 解析：关系词that 在从句中作read 的宾语，it 多余，为高考短文改错高频错点。
3. when → which/that 解析：先行词the days 指物，关系词在从句中作spent 的宾语，用
which/that。
4. who → whom 解析：介词with 后接关系代词，先行词the man 指人，用whom。
5. 无错误 解析：which 引导非限定性定语从句，指代a story，用法正确。
6. 第一个that → why 解析：先行词the reason 表原因，关系词在从句中作原因状语，用
why，改编自2025 浙江卷短文改错真题。
7. where → which/that 解析：先行词the factory 指物，关系词在从句中作visited 的宾语，
用which/that。
8. 去掉it 解析：as 引导非限定性定语从句，在从句中作know 的宾语，it 多余。
9. them → whom 解析：非限定性定语从句，先行词two sons 指人，介词of 后用whom。
10. whom → who/that 解析：先行词the student 指人，关系词在从句中作主语，

10. who → 先行词指人（athletes...journalists），非限定性定语从句缺主语
