关系副词是定语从句中连接主句和从句的关键词,在从句中作状语,指代先行词(时间、地点、原因),且不可省略。常见的关系副词有 when、where、why,三者分别对应先行词的 “时间、地点、原因” 属性,用法各有明确指向,具体解析如下:
一、关系副词的核心特征
指代对象固定:仅指代表示时间、地点、原因的先行词(名词或代词)。
句法功能单一:在定语从句中只能作状语(时间状语、地点状语、原因状语),不充当主语、宾语等成分。
不可省略:无论限制性还是非限制性定语从句,关系副词都不能省略(区别于作宾语的关系代词)。
when:指代时间,在从句中作时间状语
适用场景:先行词是表示时间的名词(如 time, day, year, moment 等),且从句需要时间状语时使用。
等价转换:when = “介词 + which”(介词根据先行词搭配选择,如 at, in, on 等)。
例: I still remember the day when I first joined the school basketball team.
先行词 从句成分:缺时间状语
表时间
转换:I still remember the day on which I first joined the school basketball team.
翻译:There was a time when teenagers didn’t worry too much about their weight.
where:指代地点,在从句中作地点状语
适用场景:先行词是表示地点的名词(如 place, city, room, gym, park 等),且从句需要地点状语时使用。
等价转换:where = “介词 + which”(介词根据先行词搭配选择,如 in, at, on 等)。
例:
The gym where we often do morning exercises has been renovated.
先行词:the gym(表地点)
从句成分:we often do morning exercises(缺地点状语 “在健身房”)
转换:The gym in which we often do morning exercises has been renovated.
翻译:This is the clinic where the doctor gave me advice on healthy eating.
why:指代原因,在从句中作原因状语
适用场景:先行词只能是表示原因的名词 reason,且从句需要原因状语时使用(注意:why 是唯一只能搭配 “reason” 的关系副词)。
等价转换:why = “for which”(固定搭配,因 “reason” 与介词 for 搭配)。
例:
She explained the reason why she refused to go on a diet.
先行词:the reason(表原因)
从句成分:she refused to go on a diet(缺原因状语 “因为这个原因”)
转换:She explained the reason for which she refused to go on a diet.
翻译:The main reason why teenagers should avoid junk food is its harm to health.
1. October 1, 1949 was the day ______ the
PRC was founded.
when
用适当的关系词填空。
3. The village has developed a lot ______ the teenagers learned farming five years ago.
where
2. I don’t believe the reason __________ he gave me yesterday and that’s the reason ______ I called him just now.
(which/that)
why
Revision:引导限制性定语从句的关系代词
关系副词:This is the park where we played.
where 作地点状语,不可省。
关系代词:This is the park that we visited.
that 作宾语,可省略: This is the park we visited.
如何区分定语从句中的关系副词和关系代词
关系副词(when/where/why)和关系代词(that/which/who/whom/whose)均用于连接主句和定语从句,但功能和用法差异显著,可通过以下 3 个关键维度区分:
一、指代对象不同
关系代词:指代人、物或事(具体或抽象的名词 / 代词)。
指人:who(主格)、whom(宾格)、whose(所有格)
指物:which、whose(所有格)
既可指人也可指物:that
例:
The girl who won the race has a healthy lifestyle.(who 指代人 “the girl”)
The book which introduces healthy diets is popular.(which 指代物 “the book”)
关系副词:仅指代表示时间、地点、原因的名词,且指向性固定。
when → 指代时间名词(如 day, time, year)
where → 指代地点名词(如 place, gym, clinic)
why → 仅指代原因名词 “reason”
在从句中充当的成分不同(最核心区别)
关系代词:在定语从句中充当主语、宾语或定语(必须作成分,否则句子不完整)。
例: The doctor who advised me is very experienced.
(who 在从句中作主语,从句完整结构:who advised me)
The diet that I followed kept me fit.
(that 在从句中作宾语,从句完整结构:I followed that)
She is the student whose eating habits are worth learning.
(whose 在从句中作定语,修饰 “eating habits”,表 “…… 的”)
关系副词:在定语从句中仅充当状语(时间、地点、原因状语),不涉及主语、宾语等核心成分。
例: I still remember the morning when we started jogging.
(when 在从句中作时间状语,从句完整结构:we started jogging (on the morning))
This is the clinic where I got diet advice.
(where 在从句中作地点状语,从句完整结构:I got diet advice (in the clinic))
The reason why he refused junk food is clear.
(why 在从句中作原因状语,从句完整结构:he refused junk food (for the reason))
、能否省略的规则不同
关系代词:
作主语时不可省略(如 who/which/that 在从句中作主语);
作宾语时可省略(如 that/which/whom 在从句中作宾语)。
例:
The recipe(that)I tried yesterday was delicious.(that 作宾语,可省略)
The trainer who helped me is from America.(who 作主语,不可省略)
关系副词:任何情况下都不可省略,无论限制还是非限制性定语从句。
例:
The moment when we decided to keep fit can’t be forgotten.(when 不可省略)
Her hometown, where she learned to cook healthy meals, is beautiful.(where 不可省略,非限制性从句)
快速判断技巧:用 “补全法” 验证
若不确定是关系副词还是关系代词,可尝试给从句补全状语(介词 + 先行词):
若补全后句子通顺,说明从句缺状语,用关系副词;
若补全后句子不通顺,说明从句缺主语、宾语等,用关系代词。
例:
This is the hotel ______ we stayed.
补全:we stayed in the hotel(通顺,缺地点状语)→ 用 where(关系副词)。
This is the hotel ______ we visited.
补全:we visited in the hotel(不通顺,实际缺宾语 “the hotel”)→ 用 that/which(关系代词)。
03. Practice
Below is a part of a magazine article about sleep problems. Find the sentences with restrictive relative clauses in the article and fill in the box below. The first one has been done for you.
Part A
Do you remember a time when you had no worries stopping you from getting a good night’s rest
One of the reasons why people fail to get a good night’s sleep is pressure from school or work.
They are still growing, and night is the time when their bodies grow faster.
Teenagers who do not sleep well may experience situations where body development slows down, and their health suffers.
Do you remember a time

Teenagers who do not sleep well may experience situations.
Body development slows down, and their health suffers in the situations.

关系副词的作用
①连接:连接定语从句和主句
②替代:关系副词=介词+which
③成分:在定语从句中一般作状语
【拓展】
1) 当situation, case, point (地点), occasion(场合)等充当先行词,且在定语从句中作地点状语时,定语从句引导词用where;如:
You could get into a situation where you have to decide immediately.
你可能遇上一种情况,使你不得不立刻作
出决定。
Three hours later, our bus reached the point where the road divides.
三小时后我们的车到达路的分岔处。
2) 当point (时刻),occasion(时刻)在定语从句中作时间状语时,定语从句引导词用when。如:
We had reached the point when there was no money left.
我们曾落到身无分文的地步。
Occasions are quite rare when I have the time to spend a day with my kids.
我能跟孩子们待一整天的时候很少。
3) 先行词是reason或cause, 定语从句中缺状语,
用why引导;如果定语从句缺主语, 宾语或表
语,则用that或which引导。
① Could you tell me the reason __________ he
gave you yesterday
② We’d like to know the reason _______ she
didn’t accept the job.
③ He gave us a reason __________ seemed to be
workable.
④ The cause _________ the car exploded has
been found out.

①根据先行词来确定
The money _______ which you were to buy dog food is gone.
He will never forget the day ____ which he failed in the exam.
介词的确定方法
with
on
②根据定语从句中的谓语动词或形容词确定
We thought you were a person _______ whom we could expect good ideas.
The West Lake, ____ which Hangzhou is known, is a great place.
from
for
③根据定语从句所表达的意义来确定
Air, ________ which man can’t live, is really important.
The pen _____which he is writing now was bought yesterday.
without
with
Is this the watch that you are looking for
The old man whom I am looking after is better .
注意: 紧跟介词后的关系代词不可省略,固定短语中的介词不可提前至关系代词前。
提问:下面两句中的介词能提前吗
特殊情况与易错点
先行词表抽象地点时,用 where:
有些名词看似不表具体地点(如 case, situation, point, activity 等),但表示 抽象场景 / 情境 时,视为 抽象地点,用 where 作状语。
例:We’ve reached a point where we need to change our unhealthy habits.(point 表 “阶段 / 程度”,抽象地点)
2.避免重复使用状语:
关系副词已在从句中作状语,不可再用时间 / 地点 / 原因副词(如 then, there, so)。
错误:I remember the day when we met there.
(there 多余,因 when 已表时间状语)
正确:I remember the day when we met.
3. 非限制性定语从句中仍可用关系副词:
逗号隔开的非限制性定语从句中,关系副词正常使用,不影响指代和成分。
My high school, where I spent three happy years, will hold a reunion next month.
Write a short passage paragraph using restrictive relative clauses where necessary.
Part B3
In a society where people are under a lot of pressure, sleep problems have become very common. That is the reason why World Sleep Day is celebrated every year on the Friday of the second full week of March. Its aims are to make people understand the importance of good and healthy sleep and to draw society’s attention to sleep problems. It is a time when people have discussions and give talks about the importance of healthy sleep.
Sample
There’s a small town famous for its traditional food culture.
The old street ______ vendors sell handmade noodles has a history of over 100 years. Locals say the best time to visit is early morning, 2.______ the first batch of noodles is served with hot broth. The restaurant 3.______ my grandfather worked as a chef for 40 years still uses his secret recipe for soy sauce. Many customers wonder 4.______ the sauce tastes richer than others—some guess it’s because of the special fermentation process. There was a time ______ only local ingredients were used, but now imports add new flavors. However, the core reason ______ the town’s food remains beloved is its focus on freshness and tradition.
