一、 用that，which引导的定语从句 1. 通常只用that的情况 （1） 当先行词为不定代词all, few, little, much, something, anything, nothing, everything, none等时；或者当先行词被序数词、形容词的最高级和 all, any, every, each, few, little, no, some, the only, the very, the same, the last 等单词修饰时，定语从句要用that来引导。
例1His brother did ______ he could to help him.
A. all which B. all what
C. all D. which
解析： 本句中的did是及物动词，用all作did的宾语，all后面省略关系代词that，he could 作为定语修饰all，故选C。
（2） 如果定语从句修饰两个先行词，其中一个指人，一个指物，那么，定语从句的关系代词应用that 。
例2The famous writer and his works that the radio broadcast have aroused great interest among the viewers.
本句中的定语从句有两个先行词，一为writer，一为works，故其关系代词为that。
（3） 在以every time, the first time, the moment, the minute, immediately, the day, the period等词语引导的时间状语中，用that而不是用when 来引导修饰表示时间的名词或短语的定语从句，that也可省略。

本句中用that引导定语从句，修饰表示时间的短语the minute。
2. 通常只用which的情况
（1） 当引导非限制性定语从句，指物或指代前面整个句子的内容时，只能用which。
例4Jim passed the driving test, _________ surprised everybody in the office.

C. this D. it
解析： 选项所在的句子是非限制性定语从句，用which指代前面整个句子的内容，故选A。
（2） 如果一个句子中有两个定语从句，其中一个用that作关系代词，另一个须用which。
例5Let me show you the novel that I borrowed from the library which was newly open to us.

二、 用who，whom，whose引导的定语从句
1. 如果先行词是指人的不定代词，如：anyone, anybody, everyone, everybody, someone, somebody, nobody, one, ones, those, all等，关系代词在定语从句中作主语时用who，作宾语时用whom / who。

A. who; 不填 B. 不填; who
C. who; who D. 不填; 不填

3. 在定语从句中，可以作定语的关系代词只能用whose，表示某物时相当于“the + 名词 + of + which”或“of + which + the + 名词”；表示某人时相当于“the + 名词 + of + whom”或“of +whom + the + 名词”。
例8Last month, part of Southeast Asiawas struck by floods, from
effects the people are still suffering.

C. those D. what
解析： 选项中作定语的关系代词只有一个，即whose, 相当于the effects of which。故选B。
三、 用where，when，why引导的定语从句
where，when，why的意义相当于“介词+ which”。具体而言，where 相当于 “in / at + which”，when相当于“at / in / during + which”，why相当于“for + which”。
1. 关系副词 where引导定语从句时，只能在定语从句中作地点状语，定语从句修饰的先行词必须是表示地点的名词。
例9I walked in our garden, ______ Tom and Jim were tying a big sign onto one of the trees.
A. which B. when
C. where D. that
解析: 选项在其引导的定语从句中作地点状语，其先行词garden是表示地点的名词，故定语从句的关系词须用where。答案为C。
2. 关系副词 when引导定语从句时，只能在定语从句中作时间状语，定语从句修饰的先行词必须是表示时间的名词。
例10There was time

A. a; that B. a; when
C. that; that D. the; when
解析： 本题考查了there be句型和定语从句的相关用法。在there be 句型中，主语之前常用a / an 等非特指的限定词修饰；when 作为关系副词引导定语从句，修饰表示时间的先行词。故选B。
3. 关系副词why引导定语从句时，只能在定语从句中作原因状语，定语从句修饰的先行词必须是表示原因的名词。
例11He refused to disclose the reason why he did it.
本句中的定语从句的先行词是reason，关系副词why相当于“for which”。
例12Is this the reason _______ at the meeting for his carelessness in his work?
A. he explained
B. what he explained
C. how he explained
D. why he explained
解析： 选项的先行词the reason尽管表示“原因”，但它在从句中作explained的宾语，其后是限制性定语从句而不是原因状语，应用that或which引导定语从句，此处也可以省略，故选A。
四、 用as引导的定语从句
1. 当先行词与as，so，such，the same 连用时，常用关系代词as来引导定语从句。
例13Children should read such books _____ will make them better and wiser.
A. which B. that
C. what D. as
解析： 选项的先行词books与such 连用，定语从句的关系代词应用as。答案为D。
2. 当引导非限制性定语从句时，指代前面句子的内容时关系代词可用which或as；指代后面句子的内容时只能用as。如：as is known to all， as we all know， as （it） often happens， as has been said before， as was expected， as is said above， as is mentioned above， as is reported等。
例14As is often the case, we have worked out the production plan.
五、 定语从句的其他特殊句式
1. 当关系代词作介词宾语，且该介词不和从句的谓语动词构成固定短语时，介词可以提前，这样就出现了“介词+关系代词”的结构引导定语从句的形式。当先行词指物时用“介词+ which / whose”， 指人时用 “介词 + whom / whose”，且关系代词不能省略。
例15I saw a woman running towards me in the dark. Before I could recognize who she was， she had run back in the directionshe had come.
A. of which B. by which
C. in which D. from which
解析： 此题考查由“介词+关系代词”引导的定语从句。根据句意，用from which表示“所来的那个方向”的意思，故选D。
2. the way 作先行词时，其后引导词作定语从句的状语时用in which、that 表示，或者省略。
例16What surprised me was not what he said buthe said it .
A. the way B. in the way that
C. in the way D. the way which
解析： 本句中not...but 连接两个并列成分，即the way及修饰它的定语从句和what引导的宾语从句作并列表语。the way作先行词，其后定语从句的引导词作状语可用in which或that，此处被省略。故选 A 。
3. but、than引导的定语从句
but 可作为关系代词引导定语从句，同具有否定意义的主句连用时，有双重否定的意味，其先行词可以是人，也可以是物。此时but在意义上相当于“that...not”“who...not”“which...not”，只用于限制性定语从句中。
例17There are very few but admire his talents.
此句的关系代词but在从句中用作主语，其先行词是few，but相当于“who don’t”的意思。
than作关系代词用在带有比较意义的句子中，其结构为：比较级...than＋定语从句。
例18The boy has had more
food than is good for his health.
关系代词than在从句中用作主语，其先行词是food。
4. 含有插入语的定语从句
辨别含有插入语的定语从句是否正确的方法是：去掉插入语后，原句的结构是否仍然完整。常见的插入语有： I think（suppose, expect, believe, imagine）, in my opinion, to tell you the truth等。
例19He made another wonderful discovery, ______ of importance to science.
A. which I think is
B. which I think it is
C. which I think it
D. I think is
解析： 本句中的I think 是插入语，which 引导非限制性定语从句，故选A。
