第 1 讲 定语从句
在复合句中，修饰某一名词、代词或整个主句的从句叫定语从句。被修饰的名词或代词
叫先行词，引导定语从句的词叫关系词，定语从句放在先行词的后面。
A real friend is someone who① walks in when the rest of the world walk out.A real friend is
someone whose② support we can count on.A real friend is someone who① sees our true self，not
just the face who/whom/that③ we show to the world.Yet these days，the modern tools that keep
us connected are eating away at the meaning of friendship.We may be able to make many friends
online，but these friendships can be quite shallow.Social media like blogs has come between us
and the friends who/whom/that③ we love.Texting and messaging cannot take the place of face-to-
face chatting.“Sharing” our experiences on social media is not enough to express the values
which/that④ matter most to us.“Liking” our friends’ photos online does not develop the
connection which/that④ we share.To make friends a real part of our lives，we should put down
our smartphones and meet them in person.
[规则感悟] ①关系词指人作主语，可以用who，that引导。若先行词为someone，anyone，
one等时，关系词只能用who。②关系词作定语，用whose引导，既可以指人也可以指物。
③关系词指人作宾语，可以用who，whom，that引导。④关系词指物作主语或宾语，可以
用which，that引导。
1．who，whom和whose引导的定语从句。
(1)who和whom都指人。who在定语从句中作主语、宾语；whom在定语从句中作宾语，在
限制性定语从句中可省略。在口语中可用who代替whom。
(2)whose指人的或物的，在定语从句中作定语，指物时可用of which代替，指人时可用of
whom代替。
Some people who are successful language learners often fail in other fields.有些成功的语言学习者，在其他领域常常会失败。
I have many friends (who/whom) I’m going to send postcards to.
我有很多朋友，我打算寄明信片给他们。
My eldest son，whose work takes him all over the world，is in New York at the moment.
我的大儿子目前在纽约，他的工作使他在全世界到处跑。
2．that和which引导的定语从句
that代替的先行词可以是人也可以是物，但是which代替的先行词只能是物。使用这两个关
系词要注意以下两点：
(1)6种只用that引导定语从句的情况。
①先行词是all，everything，anything，nothing，something，little，much，none，few，the
one等不定代词时。
②先行词被all，any，few，every，no，little，much，some等修饰时。
③先行词被序数词、形容词最高级修饰或先行词本身是序数词或形容词最高级时。
④先行词被the only，the very (正是，恰是), the last修饰时。
⑤先行词既有人又有物时。
⑥当主句是以which开头的特殊疑问句时。
(2)4种只用which引导定语从句的情况。
①引导非限制性定语从句时。
②先行词为物，关系代词充当介词的宾语，且介词位于关系代词之前时。
③先行词本身是that时。
④关系代词后有插入语时。
3．as引导的定语从句
as引导限制性定语从句主要用于 the same...as...，such...as...和so...as...结构中。 as既可以指
人也可以指物，在从句中可作主语、宾语和表语。
We have found the same materials as are used in their factory.我们已经找到了和他们工厂里使
用的一样的材料。
These houses are sold at such a low price as people expected.
这些房子以人们期望的低价出售了。
4．引导非限制性定语从句时as与which的区别
关系词 位置不同 表意不同
既可以放在主句前，也可以放 意为“正如……”，后面的谓语动词多用
as 在主句后，有时还可插入主句 see，know，expect，say，mention，report
中 等
which 通常放在主句之后 意为“这一点”或“这件事”等
As anybody can see，the elephant is like a snake.
正如每个人所看到的一样，这头大象像一条蛇。The number of smokers，as is reported，has dropped by 17 percent in just one year.
正如报道的那样，吸烟者的数量仅在一年内就已经减少了百分之十七。
She married again，which was unexpected.
她再婚了，这是始料未及的。
5．定语从句中的主谓一致
(1)关系代词作从句的主语时，从句中谓语动词的人称和数要与先行词保持一致；先行词是
句子时，从句的谓语动词用单数。
The recorder that has been given to me is homemade.给我的那台录音机是国产的。
(2)“one of＋复数名词”位于关系代词前作先行词，且关系代词在从句中作主语时，从句的
谓语动词常用复数，但当one前有the、the only、the very等修饰时，从句的谓语动词要用单
数。
He is one of the students who have made great progress.他是取得很大进步的学生之一。
He is the only one of the students who has made great progress.
他是这些学生中唯一一个取得很大进步的学生。

whether someone is a healthy weight.(2021·浙江1月)
2．Dr Rowan，____________ secretary resigned two weeks ago，has had to do all his own
typing.

5．When they met again，the two friends talked about lots of things and persons ____________
they could remember in the school.
6．Then Mr Green read some reviews of the play，____________ said it was a terrible one.
A recent survey has found that many people suffer from sleep problems.Some are unable to
fall asleep，some wake up in the middle of the night，and others simply do not get enough
sleep.One of the reasons why① people fail to get a good night’s sleep is pressure from school or
work.Noise pollution and light pollution in big cities may also contribute to sleep problems.In the
short term，people with sleep problems often feel tired and have trouble concentrating.In the long
term，they may be at increased risk of having a poor memory，being overweight and suffering a
heart attack.Sleep problems are especially dangerous for teenagers.They are still growing，and
night is the time when② their bodies grow faster.Teenagers who do not sleep well may experiencesituations where③ body development slows down，and their health suffers.
So，if you have trouble getting a good night’s sleep，it might be time to make some
changes in your lifestyle.
[规则感悟] ①先行词表示原因，关系词在从句中作状语，用关系副词why。 ②先行词表
示时间，关系词在从句中作状语，用关系副词 when。③先行词表示情况，关系词在从句中
作状语，用关系副词where。
1．关系副词指代的先行词及其作用。
与“介词＋关系代
先行词 关系副词 在从句中的作用
词”的关系
表示时间的名词：time， ＝at/in/on/during
when 作时间状语
day，year等 which
表示场所的名词：park，
where 作地点状语 ＝in/at/to/on which
place，country，house等
表示原因的名词：reason why 作原因状语 ＝for which
We live in an age when(in which) more information is available with great ease than ever before.
我们生活在一个比以前任何时候都容易获得更多信息的时代。
The school where(at which) I studied for only two years was three kilometres away.我只在那里
上了两年学的那所学校离这里有3 000米远。
The reason why(for which) he didn’t pass the driving test was that he lacked practice.
他没有通过驾照考试的原因是他缺乏练习。
2．有时先行词是表示抽象地点的名词，像activity，business，career，case，job，point，
position，race，stage，situation等，当从句中缺少状语时，用关系副词where。
They have reached the point where they have to separate from each other.
他们已经到了必须分手的地步。
3．先行词occasion意为“时机”时，用关系副词when；意为“场合”时，用关系副词
where。
I can remember very few occasions when he had to cancel a meeting because of ill health.
我记得他很少有因为健康不佳而不得不取消会议的情况。
Taking her with me on official occasions where many important figures are present has been a
challenge.
在很多大人物到场的正式场合带上她对我而言是一种挑战。
4．当先行词way意为“方法、方式”，且在从句中作状语时，关系词可用that，in which或
省略关系词。
It’s not what you say；it’s the way(that/in which) you say it.
问题不在于你说什么，而在于你怎么说。
5．关系副词与关系代词的选择。选用关系代词与关系副词时，首先应明确关系副词不可作主语或宾语。若定语从句中缺少主
语或宾语，则定语从句需用关系代词引导；从句的谓语是及物动词，而其后无宾语，就必须
用关系代词替代先行词充当其宾语；若为不及物动词，则从句中不需要宾语，需要用关系副
词。如：
典例1 The factory ____________ he once worked is closed now.
分析 work与factory不能直接构成动宾关系，只有后面加上介词in才能构成正确的表达形
式，work in the factory。因此可推知work为不及物动词。因此此处应使用关系副词where作
地点状语。
典例2 The factory ____________ he set up last year is operating well.
分析 该题从句谓语动词可以和先行词构成动宾结构set up the factory，所以set up 是及物
动词短语。其后缺宾语，因此此处用关系代词that或which。
对点练习
1．In the spring，a season ____________ we are learning new rhythms of life，many of us find
comfort in the natural world.(2021·天津6月)
2．They are now in a situation ____________ they need to make a practical plan.
3．That evening，____________ I will tell you more about later，I ended up working very late.
4．One day，mentally exhausted，I wrote down all the reasons ____________ this problem could
not be solved.
As is universally known，high school life is an important turning point and high school
campus is an important place in which① students study and live.Here there are many kind teachers
to whom② we can turn for help when we are in trouble.My classmates and I decided to do
something for the coming graduation.Having had a heated discussion，we agreed on making a
video with which③ we could record our experiences at school.
Material collecting took us a whole week，during which④ we interviewed our teachers and
took pictures of every aspect of school life.Some compromises were unavoidable，but the video
turned out perfect.That day on which⑤ the video was played，it was well received.The students
and teachers shared a great time，which surely gave us a great sense of achievement.
[规则感悟] “介词＋关系词”可以引导定语从句，如果先行词是物，关系词用 which，如：
①③④⑤；如果先行词是人，关系词用whom，如：②。介词可以根据与先行词的关系进行
选择，如：①③④⑤，也可以根据与从句中谓语动词的搭配进行选择，如：②。
1．若介词放在关系代词之前，关系代词指人时常用 whom，指物时常用which。另外，
whose也可以放在介词后，即“介词＋whose＋名词”结构。He is the person on whom you can depend.
他是你可以信赖的人。
He was the man from whose room the thief had stolen his bag.
他就是被小偷从房间里偷走包的那个人。
Last Sunday I bought some books from the bookstore，three of which were English novels.上周
日我从书店买了一些书，其中三本是英文小说。
2．“介词＋关系代词”结构中介词的确定：
(1)依据定语从句中动词的习惯搭配来确定
I bought a great many books，on which I spent all my money that I had saved.
我买了很多书，花光了所有的积蓄。
(2)依据先行词的某种习惯搭配来确定
I’ll never forget the time during which I spent my childhood in the country.
我永远不会忘记在乡下度过的童年时光。
(3)根据所表达的意思来确定
The colourless gas without which we cannot live is called oxygen.
没有它我们就不能生存的无色气体叫氧气。
3．whose引导的非限制性定语从句修饰物时，“whose＋名词”可以换为“the＋名词＋of
which”；修饰人时，可以换为“the＋名词＋of whom”。
The newly built cafe，the walls of which(＝whose walls) are painted light green，is really a
peaceful place for us，especially after hard work.
这家新建成的咖啡馆，它的墙壁被刷成了浅绿色，对我们来说，这真是一个安静的地方，特
别是在辛苦工作后。
特别提醒 定语从句与其他七种易混句型的区别
(一)定语从句与并列句的区别
两个句子之间若有and，but，so等并列连词或分号则为并列句，此时不需要再填引导词。
1．She has written many novels，some of __________ are interesting.
分析 which [which引导定语从句，修饰先行词novels，“some of which”在从句中作主
语。]
2．She has written many novels，and some of ________ are interesting.
分析 them [此句为and连接的并列句。]
(二)定语从句与独立主格结构的区别
定语从句有谓语动词，所以需要引导词，而独立主格结构不是句子，没有谓语动词，所以不
需要再填引导词。
1．She has collected many old stamps，most of ________ are worth thousands of dollars.
分析 which [which引导定语从句，修饰先行词stamps，“most of which”在从句中作主
语，后边有谓语动词are。]
2．She has collected many old stamps，most of ________ worth thousands of dollars.分析 them [逗号后面没有谓语动词，是独立主格结构，不需要引导词，故填them。]
(三)定语从句与地点状语从句的区别
定语从句有表示地点的先行词，而地点状语从句则没有；定语从句修饰的是先行词，而地点
状语从句修饰的是谓语动词。
1．We young people should go to the place ________ is in need of help.
分析 which/that [关系代词which/that引导定语从句，修饰先行词“the place”，且在从句
中作主语。]
2．We young people should go ____________ we’re most needed.
分析 where [where引导地点状语从句，修饰主句谓语动词go。]
(四)定语从句与时间状语从句的区别
定语从句有表示时间的先行词，而时间状语从句则没有；定语从句修饰先行词，而时间状语
从句修饰谓语动词。
1 ． I will always remember the days ____________ I lived with my grandparents in the
countryside.
分析 when [when引导定语从句，修饰先行词“the days”，且在从句中作状语。]
2．I always remember the days in the countryside __________ I see the photo of my grandparents.
分析 when [when引导时间状语从句，修饰谓语动词remember。]
(五)定语从句与结果状语从句的区别
在 the same...as...与 such...as...结构中，as 引导定语从句并在从句中充当一定的成分；
such/so...that...引导的结果状语从句中，that在从句中不作成分。
1．This is such an interesting work of art __________ all of us like.
分析 as [as引导定语从句，as在从句中作like的宾语。]
2．This is such an interesting work of art __________ all of us like it.
分析 that [such...that...引导结果状语从句。]
(六)定语从句与主语从句的区别
定语从句是形容词性从句，其作用相当于一个形容词，在整个句子中作定语，用来修饰前面
的名词或代词；而主语从句是名词性从句，其作用相当于一个名词，在整个句子中作主语。
1．____________ is known to everybody，the moon travels round the earth once every month.
分析 As [as引导非限制性定语从句，修饰后面整句话的内容。]
2．____________ is known to everybody that the moon travels round the earth once every month.
分析 It [it作形式主语，真正的主语是that引导的从句。]
3．____________ is known to everybody is that the moon travels round the earth once every
month.
分析 What [what在此引导主语从句，在从句中充当主语，而后面的 that引导的则是表语
从句。]
(七)定语从句与强调句型的区别
强调句的结构为“It is/was＋被强调部分＋that/who＋其他部分”，It is/was和that/who在句中不作任何成分，也不起连接作用，去掉后，句子依然完整。但是定语从句的关系词既起连
接作用还在从句中充当成分，去掉以后结构就不完整了。
1．It was on the morning of May 1st ____________ I met Liang Wei at the airport.
分析 that [将句子改为： I met Liang Wei on the morning of May 1st at the airport.显然，这
句话是完整的，故为强调句。]
2．It is the factory ____________ Mr Wang works.
分析 where [此句是定语从句，用上述方法转换便知 the factory 前少介词 in，故填
where。]
