二、定语从句
在复合句中，修饰某一名词或代词的从句叫做定语从句，它的作用相当于形容词，被修饰的词叫做先行词。
1、定语从句的位置。
1)定语从句一般地说要放在先行词之后，无论这个词在句中充当何种成分。
The student who answered the question is Bill.
2)有时先行词后还有一个作定语的词或词组时，定语从句则应放在上述成分之后。
Do you know anyone in our class whose father is a business man?
2、定语从句的引导词
1)定语从句的引导词是由关系代词或关系副词充当的。
关系代词有who/whom/whose/that，关系副词有when/where/why,它们除了引导从句的作用外，还要在从句中充当一定的成分。关系代词和关系副词的选用要看其在从句中发挥的作用，与主语没有任何关系。
在从句中充当主语的有who/which/that.
在从句中充当宾语的有whom/which/that.
在从句中充当定语的有whose.
在从句中充当状语的有when/where/why.
当定语从句所修饰的先行词是人时，关系代词要用who(主格)，whom(宾格)，也可以用that,以及whose(所有格)，先行词是物时，关系代词要用which,也可用that, whom/which/that在从句中作宾语时往往可以省略。
例如：
The students who do not study hard will not pass the examination.
Do you know the man (whom) Mr. Green shook hands with?
The letter (which) I received yesterday is from my sister.
Who is the man (that) is reading a magazine over there?
The book (that) you lent me is very interesting.
I will never forget the day when I joined the party.
Last year I went to the village where I was born.
This is the reason why she will go to London.
2)在先行词相同的情况下，根据它们在定语从句中所起的语法作用，可用不同的引导词连接不同的定语从句。
例如：
This is the school where I studied for six years. (先行词school表地点)。
This is the school which he mentioned just now. (school作mentioned的宾语)
