If winter comes , can spring be far behind ?( P. B. Shelley , British poet )
冬天来了，春天还会远吗？( 英国诗人, 雪莱. P. B.)
If you doubt yourself , then indeed you stand on shaky11 ground .(Ibsen , Norwegian dramatist )
如果你怀疑自己，那么你的立足点确实不稳固了。 (挪威剧作家 易卜生)
If you would go up high , then use your own legs ! Do not let yourselves carried aloft; do not seat yourselves on other people’s backs and heads . (F. W . Nietzsche , German Philosopher)
.
The first place (that) we’ll visit is the Great Wall.
3) 先行词被the only，the very修饰时：
The only thing that matters is to find our way home.
This is the very book (that) I’ve been looking for.
4) 先行词既有人又有物时：
They talked about the persons and things (that) they remembered in the school.
5) 当主句是由who或which引导的特殊问句时，为避免重复，定语从句中常用that：
Who is the man that is standing by the door?
Which is the dictionary (that) you bought yesterday?
只能用which 的两种情况
1) 非限制性定语从句,先行词为物
e.g. Yangtze river, which is the third longest river, lies in China.
2) 整句话当先行词
It rained a lot, which made a flood happened
只能用as, 不能用which, that, who 的两种情况
1) 先行词被such, the same 修饰时
e.g. I’ve never heard of such a terrible earthquake as you told me.
You are using the same pen as I lost yesterday. (像，两支)
You are using the same pen that I lost yesterday.（正是，同一支）
2) 非限制性定语从句提前,关系词用as,“正如…所知道,所期望…的一样”
e.g. As we know，Taiwan belongs to China,
当先行词是anyone, those, these, he, she等代词表“人”时，一般用who而不用that：
Anyone who wants a ticket please sign your name here.
Those who want to go to the English party must be at the school gate by 7:30 p.m.
He who doesn’t reach the Great Wall is not a true man.
当关系代词在定语从句中作表语时，通常用that而不用who：
He is no longer the man that he used to be.
II. 关系代词whose的特殊用法（只用作定语, 若指物，它还可以同of which互换, of which可置于其所修饰的名词前或后; 若指人, 可以同of whom互换）。例如：
Please pass me the book whose cover is green.（指物）
=Please pass me the book the cover of which (of which the cover) is green.
The doctor, whose name was Johnson, lived in a small town in the north of England.（指人）
= The doctor, the name of whom was Johnson, lived in a small town in the north of England.
III. 一种特殊的非限制性定语从句
在非限制性定语从句中，有时根据句子意思，常把some, any, none, all, both, several, many, most, neither, either等词、分数或百分比与of whom或of which连用。
He has five children, two of whom are abroad.
(比较：He has five children, and two of them are abroad.)
We have tested three hundred types of boots, none of which is/are completely waterproof.
(比较：We have tested three hundred types of boots, but none of them is/are completely waterproof.)
Ⅳ. 定语从句中易犯的错误
1. 在定语从句中加了多余的定语
e.g. Some of the boys I invited them didn’t come. (them)
2. 把定语从句谓语动词的单复数弄错
e.g. Anyone who break the rules will be punished. (breaks)
Those who has finished may go home. (have)
He is the only one of the teachers who know English in our school. (knows)
This is one of the rooms that is free now. (are)
3. 误省略了定语从句中做主语的关系代词
e.g. Children ∧ eat a lot of sugar often have bad teeth. (who / that)
4. 定语从句中加了多余的关系副词或介词
a). The house where he lives in needs repairing. ( where he lives 或 that he lives in)
b) I still remember the day on when I first came to Beijing. ( the day when 或 the day on which)
5. 在作先行词的时间名词或地点名词后错用关系代词或关系副词
I still remember the day when we spent together. (that / which)
This is the house where we lived in last year. (that /which)
6. 在先行词reason 后错用关系副词why
I don’t believe the reason why he has given for his being late. (that /which)
7. 主句不完整,首先要补充完整
This factory is ∧ that I worked in. (the one )
8. what 引导的名词性从句做主语,宾语,表语
That can be done has already been done. (what)
9. 误将强调句型当定语从句
I was in the kitchen where the fire broke out. (that)
Correct the mistakes
1. This is the last lesson which Mr. Smith taught me.
2. I have read all the books which you lent me.
3. Is there anything else which I can do for you?
4. Tom and his dog which were here a moment ago have disappeared.
5. He lives in the room, the window of that faces the south.
6. Do you still remember the day when we first spent together?
7. He is the only one of the experts who know a little Chinese.
8. Who is the man who shook hands with you just now?
9. Is this museum that they visited yesterday?
10. His father died last year, who made him sad.
11. All what you should do now is to take a good rest.

14. I had never heard such an interesting story like he told.
15. People who has eyes can sometimes act just as foolishly as the blind men.
经典例析
典型例题分析
高考题
1．All ____ is needed is a supply of oil. ( ’89 )
A. the thing B. that C. what D. which
点拨：本题考查引导定语从句的关系词，what只能用于名词性从句，因此A/D可以排除，又因先行词为不定代词all，所以答案为B。
2．He paid the boys $10 for washing ten windows, most of ____ hadn’t been cleaned for at
least a year. ( ’90 )
A. these B. those C. that D. which
点拨：本题考查非限制性定语从句。从句子结构上看，两句之间用的是逗号，无连词连接，故确定为从属句，介词后面的关系代词代物，只能用which，答案为D。
3．In the dark street, there wasn’t a single person ____ she could turn for help. ( ’92 )
A. that B. who C. from whom D. to whom
点拨：本题考查定语从句中介词加关系代词的用法。根据句意“向某人求助”是turn to
sb. for help，其中介词to可提前，故答案为D。本句也可以如下表达：In the dark street, there wasn’t a single person (who/whom/that) she could turn to for help.)
4．Dorothy was always speaking highly of her role in the play, ____, of course, made the
others unhappy. ( 2000 )
A .who B. which C. this D. what
点拨：本题考查非限制性定语从句指代整个句子的用法，意为“老是自赞她在剧中表演
的角色，这件事当然令他人不快。”指代前面所说的整句话，用which。故答案为B。从句中插入of course增加了考测难度，解题时可先把它忽略。
易混题(1)
5．①John is the only one of the students who ____ French．
②John is one of the students who ____ French．
A．know B．knows C．knowing D．known
点拨：答案是①B②A。在句①中的句意是“约翰是学生中唯一懂法语的那个学生”，其重心是the only one故从句谓语动词应与one一致。在句②中的句意是“约翰是懂法语的学生中的一个”，也就是“懂法语的学生不止一个，约翰只是其中之一”，其重心是the students，故从句中谓语动词应与students一致。
6．①This is the knife ____ I usually cut my pencil．
②This is the knife ____ I usually use to cut my pencil．
A．with which B．which C．by which D．with that
点拨：答案是①A②B。在句①中，定语从句的句式是cut my pencil with the knife，故用with which引导定语从句。在句②中，定语从句的结构是use the knife to cut my pencil，故用which引导定语从句。
7．①Who lives in the house ____ windows face south？
② Who lives in the house ____ the windows face south？
A．whose B．which C．of which D．that
点拨：答案是①A②C。在句①中windows前没有定冠词，它所缺的是定语形容词，而whose的用法就是在定语从句中作定语且既可指人也可指物。在句②中windows前有定冠词，所以要填的内容不能作前置定语，又因为“房子的窗户”用英语表达是“the windows of the house”，故可用of which引导定语从句。
8．①Is this factory ____ you visited last year？
②Is this the factory ____ you visited last year？
A．that B．of which C．the one D．where
点拨：答案是①C②A。在句①中factory前没有定冠词，这说明this是作它的定语。这样，句中就缺少表语，也就是说定语从句缺少先行词，故选C（the one后省略了that）。在句②中this作主语，the factory作表语，其后带一个that引导的定语从句，故选A。
9．①When I have trouble，he is the only one ____I can ask for help．
②When I have trouble，he is the only one ____ I can go for help．
A．whom B．to whom C．which D．to who
点拨：答案是①A②B。句①中，在结构上所要添的内容在从句中作ask的宾语其句式是ask sb．for sth．，故用whom引导定语从句。在句②中，go是不及物动词其句式是go to sb．for sth．，故用to whom引导定语从句。
10．①The reason ____ he gave us was that his car broke down on the way．
②The reason ____he was late was that his car broke down on the way．
A．for which B．which C．how D．what
点拨：答案是①B②A。在句①中，所要填的内容在定语从句中应作gave的宾语，故应填关系代词which。在句②中，所要填的内容在定语从句中作原因状语，故应填关系副词for which(=why)。
易混题(2)
一．定语从句与并列句（注意用标点符号和连接词and, but等来区别。）
1.Mr Li has three daughters, none of________ is an engineer.

3.Mr Li has three daughters; __________ are doctors.
答案：1.whom 2. them 3. None/They
二. 定语从句与地点状语从句（看是否有先行词，如果有，就是定语从句，如果没有，就是状语从句）

2.I still remember the farm_____ my parents worked ten years ago.
答案：1.where 2. where/on which
对比下面两个句子：

练习：The visitor asked the guide to take his picture _____ stands
the famous tower.
A. that B. where C. which D. there
答案: B.
三. 定语从句与强调句
强调句型可以还原成正常语序的句子，也就是说，强调句型中去掉It be… that后，句子仍然通顺，意义也依然完整，只是没有那么强调突出。而定语从句去掉了It be… that后句子就不完整了。
1. It is on the morning of May 1st _____ I met John at the airport.
It is the morning of May 1st _____ I met John at the airport.
2. It is in the factory _______John works.
It is the factory _______John works.
练习：3.It was 5 o’clock in the morning _____he arrived home.
答案:1. that ,when 2.that, where 3. where
四. 定语从句与结果状语从句
在定语从句中，若先行词被such 修饰时，关系词要用as, 组成such…as结构.这个结构与状语从句such…that…（如此…以致…）很相似，要注意区别。若从句中的及物动词后无宾语，就是定语从句， 用such…as.否则就是状语从句，用such…that.
1.I have the same computer _____you have. ( as)
2. She is such a kind girl _____all of us like to make friends with her. (that)
对比下面两个句子：
He is such a good teacher as we all love and respect.

2.It was the time _______Chinese people had a hard life.
答案: 1.that 2.when
六. 定语从句与单句（注意标点符号。两个单句间用句号， 而定语从句两个句子间用逗号。）

2.The mother told the lazy boy to work. _____didn’t help.
练习：3.There are 56 students in our class, most of ____are girls.
A. which B. whom C. them D. that
答案: 1. which 2. It 3. B
七. 定语从句与名词从句
1。定语从句与同位语从句的区别。
首先看引导从句的关系词that是否在从句中充当句子成分。如果在从句中充当主、宾、表，则是定语从句。再看that前的名词是否是一些需要有内容的名词，如：idea, fact, thought, news等。后面的从句是说明其内容的，（这个名词在后面的从句中部充当任何成分），这个从句则是同位语从句
2。强调句型与主语从句的区别：强调句型可以还原成正常语序的句子，也就是说，强调句型中去掉It be… that后，句子仍然通顺，意义也依然完整，只是没有那么强调突出。而含主语从句的复合句中的it是指示代词，后面多为系表结构或被动语态。如果去掉It be…that，句子就不通顺了。
1.The news ______came from the front was true.
2.The news ______he won the game was true.
3.She was not ______she used to be.
4.The city is no longer a place _____ it used to be.
