Boys and Girls !定语从句1。什么叫定语从句？
在复合句中，修饰名词或者代词
的从句叫定语从句。
被修饰的词叫先行词，引导定语从
句的词叫关系词。关系词有关系代词
that, which,who, whom, whose和关系
副词where,when,why。关系词放在先行
词和定语从句之间，起联系作用，同
时又作定语从句的一个成分。例句：
1.The necklace which you gave me was for my
birthday.
2.The foreigners who visited our school were
from France.
以上句中的necklace和foreigners分别是定语
从句which you gave me 和 who visited our
school所修饰的词，是先行词，定语从句
必须放在先行词之后。The Attributive Clauserelative pronouns关系代词引导的定语从句的具体用法：
1. that, 可指人或物,在从句中作主语或宾语。
A plane is a machine that can fly.
The noodles (that) I cooked were delicious.
Who is the man that is reading a book there.
The girl (that) we saw just now was Lily.
2. which,指物，在从句中作主语或宾语。
The fish (which) we bought were very fresh.
3. who,whom在从句中分别作主语和宾语。
（作宾语时可以省略）
The boy who broke the door is called Tom.
The person to whom you talked is Mr Li . 4. whose 所有格，指人，在从句中作定语
What is the name of the boy whose father is a
railway worker.
注意：关系代词在从句中作介词的宾语时，
可以跟介词一起放在主句和从句之间，也可
以把介词放在从句中有关动词的后面。
This is the room in which we lived last year.
This is the room which we lived in last year.
但含有介词的短语动词的各个固定部分
不可折开，介词仍放在动词后面。
The baby whom the nurse are looking after
are very healthy.关系代词that和which 都可指物,但使用时应注意:
1.在下列情况下只用that，不用which
(1)先行词是all, everything, nothing, anything, little, much, the one等不定代词时
There is nothing ( that ) I can do.
I mean the one that was brought yesterday.
(2) 先行词被all, any, every, no, some, little, much等饰时
I have read all the books (that) you gave me.
You may take home any of these books that you like.
(3)先行词被序数词或形容词最高级修饰时
This is the first composition (that)he has written in English.
This is the best novel (that) I have ever read.(4)先行词被the only, the very, the same, the last修饰时,如:
He is the only person that I want to talk with.
(5)先行词既有人又有物时，如:
They talked about persons and things that they met.
(6)当句中已有who时，为避免重复，如：Who is the man that is giving us the
class? 1.The white flower is the only one____ I really like.
2. This is the very book _____I want to find.
3.The last place____we visited was the hospital.
4. This is the same watch ___I lost yesterday.
5. He talked about the teachers and
school____he had visited.关系副词有

1.关系副词when指时间，只能跟在 hour,
moment, day, month, year, season, time等表示
时间的名词后,在从句中作时间状语：
I still remember the day when I first came to
Beijing.
I’ll never forget the time when we worked on
the farm.关系副词where指地点，只能跟在表示地点的
名词后面，如：village, town, city, home, place.
在从句中作地点状语.
