怎样判断定语从句中先行词

Answer 1

先行词是名词或代词,如果名词或代词后面有修饰它们的句子且它们在句中充当某一成分,它们就是先行词.
把先行词还原到从句中,就能判断做什么成份.
如:I
will
never
forget
the
day
when
I
first
went
to
school.(先行词是day)
从句=I
first
went
to
school
on
the
day.
(on
the
day
在从句中作状语=when)
I
will
never
forget
the
day
that
was
very
special
to
me.(先行词是day)
从句=The
day
was
very
special
to
me
(the
day
在从句中作主语=that/which)

Answer 2

先行词就是被定语从句所修饰的词。先行词在句子里的成分不是固定的，这要因句而异。至于宾语从句，就没有先行词，只有引导词。
例如：
the
book

that
you
want
is
here.(the
book
就是先行词）我想你可能要问关系词吧。引导定语从句的词。它在句子里通常作主语，宾语，表语，定语。例句中的关系词就是that,在定语从句里作动词want的宾语。
宾语从句：the
man
didn't
know
that

the
girl
was
an
actress.(that只起连接作用）没有语法作用，也就是不充当任何成分。
