限制性定语从句与非限制性定语从句
一、定语从句的种类
定语从句根据其与主句关系的密切程度可以分为限制性定语从句与非限制性定语从句两种。
二、定义
1．限制性定语从句：限制性定语从句是先行词在意义上不可缺少的定语，用于修饰和限定先行词。如果去掉，主句的意思就不完整或失去意义。书写时不用逗号与主句分开。
This is the MP4 that/which I bought for my daughter yesterday.
这是我昨天为女儿买的MP4。
The girl who/whom/that I saw was very learned.
我看见的那个姑娘很博学。
2．非限制性定语从句。定语从句有时与先行词的关系不是十分密切，只是作附加说明，不起限制作用，这种从句被称为非限制性定语从句，往往用逗号把这类从句与主句分开。非限制性定语从句中的关系词不能省略。
He passed the exam，which surprised his parents.
他通过了考试，这使他的父母很吃惊。
The girl，whose parents were dead，was admitted into the key university last year.
那个父母双亡的小姑娘去年被一所重点大学录取了。
三、限制性定语从句和非限制性定语从句的区别
1．形式不同
限制性定语从句与其先行词之间不用逗号隔开，非限制性定语从句与其先行词之间一般用逗号隔开。
This is an important present，which I received yesterday.(非限制性定语从句)这是一件重要的礼物，我昨天收到的。
The book that/which you borrowed last week is really boring.(限制性定语从句)上周你借的那本书真没意思。
2．功能不同
限制性定语从句与其先行词关系密切，它限制了先行词的意义。如果去掉该从句，剩余部分的意思往往不完整，甚至失去意义；非限制性定语从句只是其先行词的附加说明，如去掉，句子剩余部分意思仍然完整。
He is a man whom we can rely on.(限制性定语从句)
他是一个值得我们信赖的人。
His father，who worked in a chemical factory，died of lung cancer.(非限制性定语从句)他父亲在一家化工厂工作，死于肺癌。
3．先行词不同
限制性定语从句的先行词只能是一个名词或代词，而非限制性定语从句的先行词可以是一个词，也可以是一句话。试比较：
This is the best novel that I have ever read.
这是我曾经看过的最好的小说。(先行词是novel)
The novel，which I read last night，is very interesting.
这是我昨天晚上看过的小说，非常有意思。(先行词为novel)
The novel is very interesting，which makes me very glad.
这部小说很有意思，这让我很高兴。(先行词为“The novel is very interesting”)
4．关系词的使用情况有所不同
不同点 限制性定语从句 非限制性定语从句
使用的关系词不同 可用that，why引导 不可用that，why，要用which代替that，for which代替why
关系词的省略情况不同 关系代词作宾语时可省略 所有关系词均不可省略
The house (that/which)I bought last month has got a beautiful garden.我上个月买的那幢房子有一个漂亮的花园。
Can you tell me the reason why he was absent yesterday
你能告诉我他昨天缺席的原因吗？
This is the man (whom/who/that) we are talking about.
这就是我们正谈论的那个人。
点津：在限制性定语从句中，先行词指人时，关系代词可用who，that或whom，但在非限制性定语从句中先行词指人时，关系代词只能用who或whom。
I have a sister，who is a doctor.
我有个姐姐，她是个医生。
Our school has two foreign teachers，both of whom are from America.我们学校有两个外教，他们都来自美国。
The foreigner who comes from America teaches us English.
来自美国的那位外教教我们英语。
四、which与as引导的非限制性定语从句
1．as与which引导的非限制性定语从句的相同点：
as与which都可用来引导非限制性定语从句，来指代整个主句的内容。当非限制性定语从句位于句末且as或which在从句中作主语、宾语或表语时，两者常可互换。
He married her，which/as was natural.(作主语)
他和她结婚了，这是很自然的事。
He is an old kind farmer，which/as anybody can see.(作宾语)
任何人都能看得出来，他是一位善良的老农民。
2．as与which引导的非限制性定语从句的不同点：
不同点 as which
位置 as引导的从句可位于句首、句末或插在主句中 which引导的从句常位于句末，不能位于主句之前
动词的形式 as在从句中作主语时，常跟行为动词的主动式 which在从句中作主语时，常跟行为动词的被动式
主从句的意义 as引导的从句在意义上可与主句相悖 which引导的从句不受此限制
As is known to all，Diaoyu Island belongs to China.
众所周知，钓鱼岛属于中国。
As is expected，he has been admitted to Beijing University.
正如所预料的一样，但被北京大学所录取。
The novel is very interesting，which makes me very glad.
这部小说很有意思，这让我很高兴。(先行词为“The novel”)
(2010·北京卷)Children who are not active or________diet is high in fat will gain weight quickly.
A．what B．whose
C．which D．that
解析： 考查定语从句。句意为：不爱活动或饮食中富含脂肪的孩子会很快发胖。定语从句中diet与children之间的关系为children’s diet，即所属关系，故应用whose(＝children’s)。
答案： B
(2010·全国卷Ⅰ)As a child，Jack studied in a village school，________is named after his grandfather.
A．which B．where
C．what D．that
解析： 句意为：还是孩子的时候，Jack在以他祖父命名的乡村学校学习。根据选项此题考查从句，空格设置在名词school后，且school后有逗号，可判断为非限制性定语从句。定语从句所修饰的先行词是school，它在定语从句中作主语，因此用关系代词which。
答案： A
(2010·江西卷) The girl arranged to have piano lessons at the training centre with her sister________she would stay for an hour.
A．where B．who
C．which D．what
解析： 句意为：那位女孩计划在培训中心与她姐姐一起上钢琴课，在那里她会呆一个小时。where引导定语从句，在从句中作地点状语，修饰先行词the training centre。

A．Which；on which
B．It；when
C．As；which
D．As；when
解析： 第一个为非限制性定语从句，放在主句之前，只能用as引导，第二空替代先行词the day，在定语从句中作状语，故应用when，所以选D项。
答案： D
4．Alice received an invitation from her boss，________came as a surprise.
A．it B．that
C．which D．he
解析： 分析句子结构可知，后半句为非限制性定语从句，it与he为非关系代词，that不能引导非限制性定语从句，故A、B、D三项均不正确。which可引导非限制性定语从句，在这里指代主句的内容。

解析： 句意为：许多父母远在大城市工作的孩子在这个村子里得到了很好的照顾。children为先行词，后跟的定语从句中缺少关系代词，是孩子的父母们，表示“……的”在定语从句中用whose＋n.或of which/whom＋the＋n.或the＋n.＋of which/whom，故选B。
答案： B
7．It was a meeting________importance I did not realize at that time.
A．that B．which
C．its D．whose
解析： 关系代词的选用取决于其在定语从句中的作用，whose表示所属关系，作importance的定语。

8．Tony will never forget the days________he lived in China with his mother，________has a great effect on his life.
A．that；which B．when；which
C．which；that D．when；that
解析： 本题考查定语从句中关系词的选择。第一个空后是一个限制性定语从句，从句中缺少状语，先行词是the days，故用when，第二个空后是一个非限制性定语从句，其缺少主语，故用which，that不能引导非限制性定语从句。
答案： B
9．I feel so grateful for your selfless help，________I would not have become________I am today.
A．with which；which
B．without which；who
C．without which；what
D．with which；that
解析： 句意为：我非常感激你的无私帮助，要不我就不会像今天这样。which引导非限制性定语从句，代指主句内容，what引导表语从句，在从句中作表语。

12．Mr Smith is a teacher of much knowledge，________much can be learned.
A．whom B．from whom
C．from who D．who
解析： learn from向……学习，为固定搭配，在定语从句中from不能省略。在介词后应用关系代词whom，而不是who，故B项正确。
答案： B
13．(2011·台州高一检测)I’ve read all the books________I borrowed from the library.
A．which B．what
C．that D．who
解析： 句意为：我已读了我从图书馆借的所有的书。分析句
子结构，从空格处起至句末是定语从句，由于先行词the books受到不定代词all修饰故应用that。who指人，what不引导定语从句，故选C项。
答案： C
14．He talked a lot about things and persons________they remembered in the school.
A．which B．that
C．whom D．what
解析： things和persons是先行词。 当定语从句要修饰的先行词是既表示人，又表示物的名词时，其关系代词要用that。
答案： B
15．The reason________he didn’t come was________he was ill.
A．why；that
B．that；why
C．for that；that
D．for which；what
解析： The reason why...was that...已成为一种固定句型，这一句型中的why和that不能随意换位，也不能将that改成because，尽管that这个词在译文中可能有“因为”的含义。
