【第一篇：关系代词和关系副词基本用】
根据关系词在定语从句中的不同用法，可分为关系代词和关系副词。关系代词主要有who, whom, which, that, whose等，在定语从句中作主语、宾语、定语等;关系副词主要有when, where, why等，在定语从句中作状语。具体用法如下：
一、关系代词的用法
当先行词指人时，若它在从句中作主语，则用who;若它在从句作宾语，则用whom或who;若它在从句中作定语，则用whose。如：
The man who told me this refused to tell me his name.
告诉我这事的人不肯告诉我他的名字。
The woman whose umbrella you took is very angry about it.
你拿了那个女人的伞，她非常生气。
当先行词指物时，若在定语从句中作主语或宾语，则用which;若它在定语从句中作定语用，则用of which或whose。如：
I saw something in the paper which might interest you.
我在报上看到一样可能使你感兴趣的东西。
He’s written a book the name of which (whose name) I’ve forgotten.
他写了一本书，书名我给忘了。
二、关系副词的用法
关系副词主要有when, where, why等，在定语从句中作状语，分别表示时间、在点和原因。when主要放在time, day, years, season, age, occasion等时间的名词后;where主要放在place, city, town, village, house等地点名词后;why则通常只放在reason后。如：
Wednesday is the day when the shops are not open in the afternoon.
星期三下午商店不开门。
Give me one reason why we should help you.
给我举出一个我们应当帮助你的理由。
要特别注意，activity, case, point, even, situation, job, organization, position等抽象名词后接where引导定语从句的用法(这是近几年高考的一个新热点)。如：
I don’t want a job where I’m chained to a desk all day.
我不想找一份整天坐办公桌前的工作。
Today, we’ll discuss a number of cases where beginners of English fail to use the language properly.
今天，我们将讨论一些英语初学者对英语使用不当的问题。
The treatment will continue until the patient reaches the point where he can walk correctly and safely.
治疗将会持续到病人可以正常且安全地行走。
If you risk something important, you cause it to be in a dangerous situation where you might lose it.
你如果拿重要的东西去冒险，那你就是将它置于一种可能会失去它的危险境地。
【第二篇：高考英语定语从句的主要考】
考点一 考查关系代词whose引导的定语从句
1. A person ________ e-mail account is full won’t be able to send or receive any e-mails. (天津卷)
A. who B. whom C. whose D. whoever
【解析】C。在所给的四个关系代词中，只有whose能用于名词用作定语，故选C。又如：A bookseller is a person whose job is selling books. 书商就是其职业是卖书的人。
2. Many children, ________ parents are away working in big cities, are taken good care of in the village. (安徽卷)
A. their B. whose C. of them D. with whom
【解析】B。their是物主代词，不是关系代词，不能引导定语从句，所以不能选;在其余三个选项中，只有whose能用于名词用作定语，故选B。句意为：许多孩子的父母外出到大城市打工去了，他们在家乡被照顾得很好。
3. I was born in New Orleans, Louisiana, a city ________ name will create a picture of beautiful trees and green grass in our mind. (湖南卷)
A. which B. of which C. that D. whose
【解析】D。在所给定的四个关系代词中，只有which和whose能用于名词用作定语，故可排除B和C。而关系代词which和whose用于名词前作定语的区别是：which具有that或this的语义特征，而whose则具有one’s的语义特征。
考点二 考查关系代词which引导的定语从句
1. They’ve won their last three matches, ________ I find a bit surprising. (辽宁卷)
A. that B. when C. what D. which
【解析】D。that不用于引导非限制性定语从句，故被排除;when可引导非限制性定语从句，但只用于指时间，与句意不符，故也被排除;而what不是关系代词，不能用于引导定语从句，故也被排除;which在此引导非限制性定语从句，并在定语从句中充当动词find的宾语。句意为：他们赢了最后三场比赛，我发现这有点令人吃惊。
2. My friend showed me round the town, ________ was very kind of him. (全国Ⅱ)
A. which B. that C. where D. it
【解析】A。由于两个句子之间没有并列连词，所以不能选B或D;而where是关系副词，不能用作主语;which在此引导非限制性定语从句，并在从句中用作主语。又如：Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。
3. Whenever I met her, ________ was fairly often, she greeted me with a sweet smile. (山东卷)
A. who B. which C. when D. that
【解析】B。that不能用于引导非限制性定语从句，故可排除;when是关系副词，不用作主语，故也可排除;who用于指人，但这里的定语从句不是修饰her，而是修饰whenever I met her，故不能用who，此处应用which。又如：He said that he had never seen her before, which was not true. 他说他从没见到过她，这是不真实的。
【第三篇：关系代词whose的用法】
1. whose用作关系代词时，它并不表示“谁的”，而是表示“……的……”，在具体语境需要灵活处理。如：
He is the man whose car was stolen. 他就是汽车被窃的人。
The boys whose names were called stood up. 叫到名字的男孩们站了起来。
You are the only one whose advice he might listen to. 你是惟一可能使他听从劝告的人。
2. 不要以为whose引导定语从句时，其先行词一定是指人的名词，其实也可以是指事物(包括动物)的名词。如：
It was an island whose name I have forgotten. 这是一座岛，名字我忘了。
Wolves are highly social animals whose success depends upon cooperation. 狼是高度群体化的动物，它们的成功依赖于合作。
3. whose 不仅可以引导限制性定语从句，也可引导非限制性定语从句。如：
My bitch, whose temper is very uncertain, often bites the judges at dog shows. 我的母狗脾气不稳定，常常在狗展上咬裁判。
One of the Britons, whose identity has not been revealed, was taken to hospital. 其中一位英国人被送往医院。他的身份还没有透露。
Now was not the time to start thinking of mother, whose death had so distressed me. 现在还不是开始想念母亲的时候。她的逝世曾令我极度痛苦。
4. 引导定语从句的“whose+名词”，有时可换成其他结构，注意词序的变化。比较：
破了窗户的那座房子是空的。
正：The house whose windows are broken is empty.
正：The house the windows of which are broken is empty.
正：The house of which the windows are broken is empty.
正：The house with broken windows is empty.
5. 根据语境的需要，whose 前可以使用语义需要的介词。如：
I wish to thank Professor Smith, without whose help I would never have got this far. 我要感谢史密斯教授，没有他的帮助，我不会走到今天这一步。
Last month, part of Southeast Asia was struck by floods, from whose effects the people are still suffering. 上个月东南亚的部分地区受到洪水侵袭，现在人们仍在遭受洪水带来的影响。
