定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫作定语从句。
一、关系带词引导的定语从句
1. 关系代词用来指代先行词是人或物的名词或代词
例１：This is the detective who came from London.
例２：The book which I am reading is written by Tomas Hardy.
２．关系代词的用法
(1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that,不用which.例如： All the people that are burst into tears.（所有人都迸出眼泪。）
(2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who,或whom.
(3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。
There are about seven million people taking part in the election, most of whom、are well educated.
(4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如：
He succeeded in the competition, which made his parents very happy.
(5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。
(6) which可作表语，既可指人，以可指物。指人时，一般指从事某种职业或是有某种特征．品性或才能的人。Which引导的定语从句可以是限制性的，也可以是非限制性的。
(7) 如果作先作词的集体名词着眼于集体的整体，关系代词用which;若是指集体中的各个成员，则用who.
(8) 先行词有两个，一个指人，一个指物，关系代词应该用that.
(9) 如果先行词是anyone, anybody, everyone, everybody, someone, somebody,关系代词应该用 who 或whom,不用 which.例如：Is there anyone here who will go with you?（在这的所有人中谁和你一起去？）
３．“介词＋关系代词“是一个普遍使用的结构
(1) “介词＋关系代词“可以引导限制性定语从句，也可以引导非限制性定语从句。“介词＋关系代词“结构中的介词可以是 in, on, about, from, for, with, to at, of, without 等，关系代词只可用whom或 which,不可用 that 。
(2) from where为“介词＋关系副词“结构，但也可以引导定语从句。例如：
We stood at the top of the hill, from where we can see the town.
(3) 像listen to, look at, depend on, pay attention to, take care of等固定短语动词，在定语从句中一般不宜将介词与动词分开。例如：This is the boy whom she has taken care of. （这是她曾今照顾的孩子。）
二、关系副词引导的定语从句
1．关系副词也可以引导定语从句
关系副词在从句中分别表示时间．地点或原因。关系副词when在从句中充当时间状语，where 充当地点状语，why充当原因状语。
2. that可引导定语从句表示时间．地点或原因
That有时可以代替关系副词 when, where 或者why引导定语从句表示时间．地点或原因，在 that引导的这种定语从句中，that也可以省去。
三、限制性定语从句与非限制性定语从句
1．二者差异比较
限制定语从句紧跟先行词，引导词同先行词之间一般不加逗号，仅修饰先行词，可以由关系代词．关系副词或that来引导。非限制性定语从句仅作补充或说明，用逗号与主句隔开，既可修饰先行词，又可修饰整个主句，不可用that引导。
2．关系代词和关系副词的选择依据
(1) 弄清代替先行词的关系词在从句中作什么成分，作状语的应选用关系副词，作主语．宾语或表语的可选用关系代词。
3. 先行词与定语从句隔离
定语从句一般紧跟在先行词之后，但定语从句与先行词之间有时也会插入别的成分，构成先行词与定语从句的隔离。例如：
This is the article written by him that Is poke to you about.
四、As在定语从句中的用法
1. 引导限制性定语从句和非限制性定语从句
（１）as多与such 或the same连用，可以代替先行词是人或物的名词。
（２）as 也可单独使用，引导非限制性定语从句，作用相当于which.例如：
The elephant’s nose is like a snake, as anybody can see.
(３）the same… that与 the same …as在意思上是不同的。
2．As引导的非限制性定语从句的位置
as引导的非限制性定语从句位置较灵活，可以位于主句前面．中间或后面，一般用逗号与主句隔开，但which所引导的非限制性定语从句只能放在主句之后。例如：As is expected, the England team won the football match.

高中总复习英语定语从句专项练习卷参考答案

2．答案：B解析：本题考查定语从句。that引导的定语从句又在从句中作spend的宾语。
3．答案：D 解析：由四个选项知该空格应填入定语从句的引导词，此句意义为：people were eaten by the tiger in the scene,所以先行词scene应该与介词in搭配。
4．答案：A 解析：关系副词where引导定语从句，修饰trousers,并在定语从句中作地点状语。全句意思为：在她擦手的裤子上留下了污迹。
5．答案：D
解析：从句意看，本题考查定语从句的用法，故首先排除C项。由于when在定语从句中只能作时间状语，而题干中的定语从句缺主语，因而排除B项；as与which引导非限制性定语从句时，which引导的定语从句只能放在主句之后，而as引导的定语从句可放在主句之前，也可放在主句之后，其中as表示“正如……那样”。as is often the case为固定词组，意为“这是常用的事；正如常见的情形”。全句意思为“正如平常一样，我们已经制订出了工作计划”。最佳答案D.
6．答案：B 解析：由题干的结构及内容看，逗号之前，应为非限制性定语从句，故选B项。全句意思为：“正如报纸上报道的那样，两国之间的谈判取得了进展。”若选A项，此句应为：It is reported in the newspaper that talks between the two……若选D项，此句应为：What is reported in the newspaper is that talks between the two……

18．答案：B解析：题意是“前年，东南亚部分地区遭遇了洪水灾害，至今人们还在受此影响”。由题中的逗号可以判定出句子的后半部分是一个非限制性定语从句，先行词是floods.从句子的结构可看出，定语从句中只缺少定语，也就是说，先行词在从句中充当定语，所以引导词要用whose.
19．答案：B解析：本题考查定语从句；where引导定语从句，又在从句中作地点状语。
20．答案：B解析： where引导定语从句，what引导宾语从句。“在公司里我可以用到我所学的知识”。

25．答案：C解析：本题考查定语从句。关系副词在定语从句中作地点状语。本句中around作定语修饰a gas station.
26．答案：B 解析：本题考查冠词和定语从句的用法。time作“次数”解时，后接关系代词that引导的定语从句，即：This/It is the first/second……time that+从句；time作“一段时光（时期）”解时，其前用不定冠词，其后接关系副词when引导的定语从句，构成：There was/is a time when……。故选B.全句意思为：有这么一段时间，我不想去上学。
27．答案：A 解析：第二空是强调句型，强调的是状语in the very house.house后是定语从句，从句缺少主语，用that或which引导；由于house前有the very修饰，故只能用that引导。
28．答案：C 解析：在sb.do what one can to do结构中what one can是宾语从句，what后不可再使用关系代词；在sb.do everything/all(that)one can to do中，that one can是定语从句，该从句中只能使用关系代词that,everything/all that等于what；在以上结构中can后省略了动词do,动词不定式作目的状语。故选C.
29．答案：B 解析：第一个定语从句缺时间状语，因此第一空应该使用关系副词when；第二个定语从句缺主语，关系代词指代前面整句话，因此用which引导非限制性定语从句。
30．答案：D解析：考查定语从句。whose引导非限制性定语从句，whose指代our life journey,在从句中作定语修饰days.
