【篇一】定语从句要点回顾定语从句要点
定语从句要点
1. 定语从句：在复合句中，修饰名词或代词的从句叫定语从句 。 2. 。
3. 关系词：代替先行词，起连接先行词和定语从句的作用（两个句子必需要有连词连接）。
关系代词：
关系词
关系副词：
先行词为人（sb）: who, whom, that, whose, as
关系代词
先行词为物（sth）: which, that, whose, as
关系副词：when where why
4. 限制性定语从句和非限制性定语从句： 1. 限制性定语从句（无逗号隔开） 定语从句
非限制性定语从句（有逗号隔开）
1. 限制性定语从句，对先行词起限制修饰作用，是先行词必不可少的部分，如果去掉了定语从句，先行词就不完整，在翻译时，翻译成一个句子，关系词不翻译。
2. 非限制性定语从句，是对先行词起补充说明作用，非限制性定语从句可有可无，省略非限制性定语从句之后，主句仍然是完整的。翻译时，翻译成两个句子，先翻译主句，再翻译从句。 Eg: My father, who works in a factory, is kind. 我的爸爸很善良，他在一家工厂工作。
5. 定语从句中，关系代词的省略：在限制性定语从句中，关系代词在定语从句中作动词或介词宾语时，可省略
关系代词。在非限制性定语从句中，关系代词不能省略。 6. 关系代词引导的定语从句
在限制性定语从句中，who 代替先行词在定语从句中作均可，如who作宾语可省略。
在非限制性定语从句中，who代替先行词在定语从句中只能作主语，且不能省略。
在限制性定语从句中，whom代替先行词，在定语从句中作，如作可省略。 在非限制定语从句中，whom代替先行词，在定语从句中作，但不能省略。 sb 先行词为人时，在中只能用whom,不能用who和that。 只能用于限制性定语从句中，不能用于非限制性定语从句中，that也不能用于 that的情况）。 在限制性定语从句中，that代替先行词，在定语从句中作主/宾/表，如作宾语可省略。 1. 在限制性定语从句中，which代替先行词，在定语从句中作主/宾/表，如作宾语可省略。
which 2. 在非限制定语从句中，which代替先行词，在定语从句中作，但不可省略，即使作
宾语也不可省略。
sth 3. 先行词为物时，在中，只能用which,不能用whom/that。
1.只能用于限制性定语从句中，不能用于非限制性定语从句中，that也不能用于介词 关系 that 代词。（没有介词 that的情况）
2.在限制性定语从句中，that代替先行词，在定语从句中作，如作宾语可省略that。
7. 如何区分主从句？
1).抓住表示时态的动词 2).看哪个动词前有连词
3)连词和后面的动词构成从句，动词前没有连词的那个动词就应是主句的谓语
8. 关系副词：where, when, why
1). n（时间） when: 先行词为时间名词，并且when代替先行词在定语从句中作时间状语 Eg : The day I went to school is Sept.1st.
2). n(地点) where: 先行词为地点名词，并且where代替先行词在定语从句中作地点状语
3). n（the reason） why: 先行词为the reason, 并且why 代替the reason 在定语从句中作原因状语，只能用于限制性定语从句中，在非限制性定语从句中，先行词为the reason只能用for which, 不能用why. The reason why he was late was that he got up late.
9. 关系副词=介词（由定语从句谓语和先行词而定） which(关系代词) 主 谓 Where = in/ on/ at which 主 谓 When = in/on which 主 谓 Why = for which 主 谓
Eg: This is the house where Luxun lived. =This is the house in which Luxun lived.
=This is the house (which/that) Luxun lived in. 是否所有的介词 关系代词都能用关系副词代替?
只有当介词 关系代词充当地点状语、时间状语或原因状语时，才能用关系副词代替。
10. whose N (N’s. n v) V
Eg: The boy whose father is a worker is Tom.. The book whose cover is red is good. 无冠词) N (人/物the n of which物 人
11. 定语从句修饰名词或代词。
状语从句修饰主句谓语动词。
名词性从句，从句作为一个整体在句中作主、宾、表、同位语。 三大从句：定语从句（形容词性从句） 状语从句（副词性从句）
主语从句
名词性从句 宾语从句
表语从句 同位语从句
注意: how, what 不能引导定语从句，只能引导名词性从句（主语/宾语/表语从句）。
12. as 引导的定语从句
such, as, so 修饰时，关系代词用
as.
such a adj n that 如此…以至于…。that引导结果状语从句，that只作引导词，不充当任何成分，但
又不能省略。（不缺主宾）.
so adj a n that 如此…以至于…。that引导结果状语从句，that只作引导词，不充当任何成分，但
又不能省略。（不缺主宾）.
that只作引导词，引导结果状语从句，不充当任何成分，但又不能省略。（不缺主宾）. as as引导定语从句，在从句中作主/宾/表，但不能省略。（缺主或缺宾）. we all love and respect him. He is such a good teacherwe all love and respect.
The same n that 同一的 The same n as 同样的
Eg: This is the same pen as I lost. (同样的，不是我的) This is the same pen that I lost. （同一的，是我的）
13．as和which 引导的非限制性定语从句的区别
共同点：as和which都代替主句陈述的整件事情或主句的部分内容。（先行词不是主句中的某个名词，而是
整个主句或主句的部分内容。）
Eg: As is known to all, Taiwan is part of China./ Taiwan is part of China, as is known to all. Mary received a gift from her boss, which made her very happy.
不同点：a. 位置不同：as 从句可放在句首，句中，句末，位置灵活。which 从句，不能放在句首，只能放
在句中或句末。
b. 意思不同：as翻译成“正如”，which翻译成“ 这，这一点”。 c. as从句和主句意思一致, which从句往往与主句意思相反。 d. as通常用于被动语态中，which通常用于主动语态中。
14．特殊：
1. 当先行词为situation, scene, position, point, spot, case等时，如果定语从句主宾表不缺，一般我们用where
或in which引导。
2. 先行词是 are
is
3. 当先行词为the way时
如果定语从句中缺主/宾/表, the way在定语从句中作主/宾/表时，用关系代词that/which, 如作宾语可省略。 The way that/which (缺/主/宾/表)
如果定语从句中不缺主/宾/表，the way在定语从句中不作主/宾/表，只能作方式状语，没有相应的关系副词，只能用in which或that, in which或that, 均可省略。
4. 先行词为交通工具时，不用by which, 而用in which 或on which
The car in which The bus in which The plane on which
15．在非限制性定语从句中，定语从句的主语或宾语是先行词的一部分时，用代词或数词 of which/ whom Eg: I have ten books, five of which are interesting. =I have ten books, of which five are interesting. He has two sons, one of whom is a doctor. = He has two sons, of whom one is a doctor.
注意:
He has two sons, one of whom is a doctor.
= He has two sons, and one of them is a doctor = He has two sons; one of them is a doctor N, whose n
= N, the n of whom/which = N, of whom/which the n
16. 抽象名词表地点，如在定语从句中，作地点状语时，用where/in which引导。
17. 如果vi 介词的汉语意思＝vi, 可以把介词提到关系代词前构成 “介词 关系代词”引导定语从句， 如果vi 介词的汉语意思≠vi, 则不能把介词拆开提到关系代词前。 Eg: This is the house where/in which Lu Xun lived. This is the man to whom the book belongs.
定语从句解题步骤 1．分清主句和从句。 2．抓住定语从句谓语动词。
3．判断从句谓语动词是及物动词还是不及物动词。（如何判断？先行词如能放在动词之后构成动宾关系就是及物动词，如需加介词才能构成动宾关系就是不及物动词。） 4
如是及物动词，看定语从句谓语动词是否缺主/宾语。
如是不及物动词，看从句谓语动词是否缺主语/表语。 如是不及物动词，后面还带有介词，看介词后是否缺宾语。
5如缺主/宾(表语) ，可以判断该用关系代词，排除关系副词或介词 关系代词。
如主/宾/(表语)不缺（只能缺状语），可以判断该用关系副词或介词 关系代词，排除关系代词。
6判断出该用关系代词后，再看先行词是人还是物，确定关系代词，最后看先行词前修饰语，确定具体的关系
代词（that还是which）。(that 恰好叙述的是唯一最不确定的人物。)
判断出该用关系副词后，再看先行词是时间、地点还是原因名词，确定该用哪个关系副词或介词 关系代词。
是
【篇二】定语从句要点回顾定语从句语法知识点总结定语从句
【区别】限制性定语从句对先行词起修饰作用。
非限制性定语从句对先行词起补充说明作用，先行词与定语从句往往用逗号隔开，句子相当于并列句，状语从句。
【注】当关系代词as或which引导非限制性定语从句，修饰主句内容时，若as或which作主语，则从句的谓语动词用单数形式。 例：
【篇三】定语从句要点回顾定语从句的几个要点下面归纳一下定语从句的几个要点：
（一）由who，whom，whose引导的定语从句
这类定语从句中who用作主语，whom用作宾语，whose用作定语。
（二）由which引导的定语从句
which在从句中作主语，或谓语动词或介词的宾语，如：
This is the pen which you want.
（三）由that引导的定语从句
that在定语从句中可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语。
I never forget the day (when/ that/ on which) i went to school 20 years ago.
（四）由when，where，why引导的定语从句
先行词表示地点时，有时用where，有时用that引导定语从句。这时要根据从句的谓语动词是及物的还是不及物的来判断，是及物的就用that(which)，否则用where。如：
This is the room where he lived last year.
This is the house that (which) he visited last year.
注意：在引导定语从句中，which与that的用法区别：
1．在下列情况下，只能用that，不能用which：
(1)先行词是不定代词：all，few，little，much，something，nothing，anything等时；
(2)先行词被序数词或形容词最高级所修饰时；
(3)先行词被all，any，every，few，little，no，some等修饰时；
(4)先行词被the only，the very，the same，the last修饰时；
(5)先行词既有人又有物时。
2．在下列情况下，只能用which而不用that：
(1)如果句中有两个定语从句，其中—个用了that，另一个最好用which；
That which you told him about is what we want to know.
(2)前面紧接着有介词；
(3)非限制性从句中不用that。
（五）同位语从句与定语从句的区别：
1．从意义上：同位语从句对名词或补充说明或进行解释，而定语从句进行修饰、限定，相当于一个形容词的作用。
2．从结构上：同位语从句由连接代词，副词引导，最常用的连接词that一般不省略，也不在从句中作成分，而定语从句由关系代词/ 副词引导，that在定语从句中作主语不能省略，作宾语可省略。
3．从涵义上：同位语从句与所说明、解释的句词无逻辑关系，而定语从句所修饰的句词是该从句逻辑上的主、宾、表、定、状语等。如：
他们在比赛中获胜了，这个消息很快传来了。(同位语从句)
(the news和that they had won the game无逻辑关系)
昨天你告诉我的那个消息是真的。(定语从句)
(the news在定语从句中相当于told的逻辑宾语)
4．同位语从句说明，解释的句词有所限制，大多是一些表示抽象概念的名词，而定语从句所修饰、限定的先行
词无限制，既可指人，又可指物。
(六)as引导的定语从句
1. as引导限制性定语从句，先行词常用such和same修饰，as在从句中不省略
He used such expressions as he could find in the texts.
2. as引导非限制性定语从句时，as代表整个主句的意义，定语从句在主句中的位置比较灵活
He is a teacher, as is clear from his manner.
Taiwan, as is known to everyone, is a part of China.
【题例精析】
【例1】The farm _______ we see today is no longer the one _______ it was ten years ago.
A. that; that
C. where; where
词的选用。
【要点精析】分析句子结构可以知道，两空均为定语从句结构，表示地点的先行词the farm 在第一空的定语从句中作
谓语动词see的宾语，故第一空应为关系代词 that，which 或省略；the farm 在第二空的定语从句中作表语，故只可以用that 连接，不可用which，且不可省略。
【答案】A
【例2】I often think of the days ______ I stayed with them, ______ has a great effect on my job.
A. which; that
C. when; who B. that; which D. when; which B. where; that D. which; which 【易错点悟】解答该题的关键是要注意判断表示地点的先行词在定语从句中用作宾语或状语时，以及用作表语时关系
【易错点悟】解答该题的关键是要准确判断表示时间的先行词在定语从句中所作的成分以及非限制性定语从句中的关
系词所指代的对象。
【要点精析】句中的the days 为表示时间的先行词，在I stayed with the experts 的定语从句中用作时间状语，故第一空
的关系词应选when 或in which；第二空关系词作主语引导非限制性定语从句，代指的是前面整个句子的内容，故必须选用which连接。定语从句要点回顾
【答案】D
1．B。本题题干中的effects和先行词floods之间有所属关系，所以要用whose，这样from whose effects一起引导定语
从句。本题答案是：B。
2．A。通过分析属干可以知道。先行词表示的是一个时间段，且在从句中充当时间状语，根据这个意思，用“介词 关
系代词”引导定语从句。c项中的whose不能用来指代时间。本题答案是：A。
3．C。本题考查关系副词where在定语从句中的用法。现行词a business表示地点“公司”，在定语从句中作状语，故
选用where。
4．C。本题考查“介词 关系代词”的用法。关系代词在定语从句中作介词的宾语时。从句常常由“介词 关系代词”
引出。介词的选择，取决于与现行词成从句之间的关系。“在英语剧中扮演角色”应为act in the English play，因此关系代词which前应用介词in，故本题选C。
5．B。本题考查非限制性定语从句。非限制性定语从句不能用that引导；关系词在定语从句中作及物动词visited的宾
语，故正确答案是B。
6．D。本题考查定语从句关系词的选择。本题先行词是cases，意为“个案”。从句中不缺少主语和宾语。故应用where
引导定语从句且在从句中作状语。正确答案是D。
7．D。whose引导定语从句时，只能用作定语；其他选项均不能构成定语从句。
8．B。引导非限制性定语从句，而且可以放在句首，这时as用作从句中的主语，代替主句的内容。如果把句中的逗号
去掉，就可以选A项。
9．D。talk的意思是“交谈”，是不及物动词，后面带宾语就要带适当的介词，因为定语从句的先行词是人，一个构成
talk with sb.结构，且把介词提前。
10．D。通过分析可以知道：that evening是定语从句的先行词，但是在句子中用作介词about的宾语，所以不能用when，
要用which引导定语从句。
11．C。在第一个定语从句中，引导词作visited的宾语，应用关系代词作引导词或省略引导词；在第二个定语从句中，
I是主语，worked是不及物动词，不能带宾语，故引导词作状语，选where。
12．D。当先行词被形容词的最高级、序数词或the only，the very等修饰时，定语从句要用that引导，而不能用which。
13．A。引导词在第一个定语从句中作状语，在第二个定语从句中作主语。又因that不能引导非限制性定语从句，故选
A。
14．A。去掉非限制性定语从句中的插入语I think后，可以看出引导词在从句中作主语，故选who。
15．B。as可单独引导非限制性定语从句，指代整个主句的内容。其位置可在主句之前，也可在主句之后。
16．D。先行词1949为表示时间的词，引导词代替先行词在从句中作状语，意为共和国于1949年建立，故选when。
17．D。当先行词为all，everything，nothing，anything，much，little，few等不定代词时，定语从句常用that而不用
which引导。
18．C。两句中间为逗号且无连词，说明选项所在句子是个非限制性定语从句，可排除A、D。在B、C中，根据主谓
一致原则选C。
19．B。选项B使两句之间构成并列句，其中that为指示代词，指代前句内容；如将选项所在句子看作非限制性定语
从句，则无正确答案。
20．A。reason作先行词时，如引导词在从句中作状语，用why引导定语从句；如引导词在从句中作主语或宾语，用
that或which引导定语从句。引导词在此题中作的是explained的宾语，故选A。
21．B。引导词在从句中作主语。注意：“介词 关系代词”相当于when，在从句中作状语，what不能引导定语从句。
22．B。此题属于“one of 复数名词 定语从句”结构。在此结构中，如引导词作主语，one前有the only，the very等
修饰时，定语从句中的谓语动词用单数；如没有，谓语动词用复数。另外，so far常和现在完成时连用。
23．C。whose和of which都可作定语表示“谁的”，但whose须放在无定冠词the的名词前，of which常放在有定冠词
the的名词后。例如：China, whose area (the area of which)is about 9,600,000 sq. km., lies in the east of Asia. 中国位于亚洲的东部，它的面积为九百六十万千方公里。
24．B。此题属于“介词 关系代词”引导的定语从句。先行词指物时关系代词用which，指人时用whom。定语从句要点回顾
25．D。第一个定语从句相当于the judge gave a prize to the artist。第二个定语从句相当于I have been taught painting for two
year by the teacher。
26．B。which引导非限制性定语从句指代整个主句内容，即清洁工人好几周没打扫街道一事。
27．D。从句的主语和宾语分别是eating，much time，引导词where在从句中作状语表示地点。
28．A。由句意可知，定语从句的先行词是some pictures而不是some teachers。
29．C。定语从句相当于he invited all his friends to the club。
30．D。从句的主语family与先行词anyone有所属关系，因此选关系代词whose。
