定语从句之----关系副词/介词+关系代词

1.定语从句的基本概念 Attributive clause
2.基本要素
名词；代词    先行词
   关系词     三重作用
   从句       谓语动词形式

Which/that 之间的选择

当先行词是形容词最高级时，关系词用that
当先行词是序数词时，关系词用that
当先行词是only;very;right时，关系词用that
当先行词all;much;any;few;little;none;nothing;anything;something;many;no时，关系词用that
当先行词既指代人又指物时，关系词用that
在非限制性定语从句中，用which
在介词后面，用which

注意：非限制性定语从句中，关系词指代的可以是前面句子中的任何一个名词，也可以是前面整句话，要根据意思判断。
His father is a bad man,who is a thief.
She was late for class,which made me angry.

关系副词

1.关系副词引导...when/where/why
2.介词+关系代词：
限制性定语从句中，介词可以放在关系代词前或后。
与关系代词分开时，代词可省
Tom is a boy on whom you can depend.
=Tom is a boy whom you can depend on.
=Tom is a boy you can depend on.
非限制性定语从句中，介词不后置，代词不省
The boy cried,after which his mother came.

注意：有些含介词的短语被看成一个不可分割的整体：
look after/call on/account for/look forward to/...
This is the boy whom I must look after.
This is the boy after whom I must look.

疑问一：

1).是否所有的where都可以换成in which?
This is the school in which I used to study.
I like this library,from which I can borrow my favorite books.
I'll go to Shanghai,in which live my relatives.
where=in/at/from...+which
2).看定语从句中形容词与介词的搭配
He told me to read some useful books with which I am not very familiar.
Teach me this song in which I'm interested.
3).根据先行词判断，所用的介词与先行词搭配
This is our classroom,in the front of which there is a teacher's desk.

疑问二：

where引导的地点状语从句和
where引导的定语从句的区别

解决疑团

1.where引导的从句和其前面成分的关系
2.where在从句中做不做成分
I want to go to Shanghai where the world expo is being held.      定语从句
Where there is a will,there is a way.             状语从句
This is Hanghzhou where lies the West Lake.         定语从句
