定语从句的关联词基本与三种名词性从句的关联词相同，what只能引导名词性从句，即（主语从句、表语从句和宾语从句）合称为名词性从句。如；what
made
him
come
is
a
question.do
you
know
what
he
is
doing?定语从句需位于被修饰的名或代词之后，如；i
know
the
man
who
is
standing
there.宾语从句则直接承受主句的谓语行为，如，i
know
who
is
standing
there.注意，这也是为什么主格who经常可以换用宾格whom的原因，但介词之后的whom不可换用who,因为介词有及物的动态理念！when,where本身只是疑问时间和地点的副词用作从句关联词，因此只能在从句中用作与其本身作用相应的从句成分，如；do
you
know
where
he
is
from?do
you
know
when
he
came?when
he
came,i
had
finished
my
work.
