3.关系词：
引导定语从句的连词叫关系词。如that、which、who、whom、whose、where、when等。
4.由that、which、who、whom、whose引导的定语从句。

二、定语从句（二）
1.先行词是物时，一般情况既可用that也可用which.但下列情况下，只能用that不用which。
1).当先行词为指物的不定代词，如all、everything、something、anything、nothing、none、the one等时，只能用that。

2).当先行词被the only、the very 、the last、all、no、little等词修饰时，只能用that。

3).先行词被序数词修饰时，只能用that 。

4).先行词为最高级或被最高级修饰时，只能用that。

I have _____ seen _____ a beautiful mountian .
5).先行词既有人也有物时，只能that 。

1).关系代词前有介词时，关系词只能用which 。
This is the building in ______ he lives .
2).先行词本身是that时，关系词只能用which 。

3).引导非限定性的定语从句（先行词是物且先行词与关系词用逗号隔开），关系词用which。
His book , ______ was lost last week , has been found now.
3.先行词是人时，一般情况下既可用who 也可用that 。但以下情况下，只能用who。
1).当先行词为those、one、ones、anyone且作主语时，一般用who 。

3).当先行词是I、you、he、they等时，只能用who 。

三、定语从句（三）。
由关系副词when、where、why引导的定语从句。
where = in / at +which when = in / on / at +which why = for + which
1.由where引导的定语从句。
1).先行词是表示地点的名词 2).在定语从句中作地点状语
Is this the house ______ you lived ?= Is this the house _____ _____ you lived ?
= Is this the house _____ you lived in ?
2.由when引导的定语从句。
1).先行词是表示时间的名词 2).在定语从句中作时间状语
I will never forget the days ______ I met him .= I will never forget the days ____ ____ I met him.
注：先行词是the last time 时，when 可省略。
When was the last time you saw the parrot ?
3.由why引导的定语从句。
先行词为reason 时，一般用why 。 why在句中作原因状语。
We don’t know the reason ______ they didn’t come .
四、注意事项：
1.关系词在定语从句中作宾语时，常可省略。
The story _____ he told was very popular .
A.who B.whom C.whose D. /
2.that、who、which在定语从句中作主语时，定语从句的谓语动词应与先行词保持一致。
I loves singers who _______(write) their own songs .
She is one of the girls who ______(study) hard .
3.在定语从句中不能出现代替先行词的人称代词。
Will you please show me the book ______ yesterday?
A. which you bought B. that you bought it C. you bought D. you bought it
4.定语从句中whose 的确定：
无论先行词是人或物，在定语从句中做定语用whose。
判断：看定语从句的主语前有无限定词（my、your、Jim’s等），若没有，则用whose 。
The girl _____ parents work in Beijing is Kate .
A. who B. whose C. which D. that
I know the boy . His handwriting is very good .= I know the boy ____ handwriting is very good.
