Question

麻烦高手帮忙告诉我关系代词和连接代词的区别

Answer 1

你对句子的理解是对的。what的确在从句中做的是宾语。
连接代词that
在从句中不做成份，而关系代词that
在从句中是要做主语或宾语的。
It
is
all
known
that
he
is
a
great
teacher.
We
all
know
that
he
is
a
great
teacher.
这两句中的that都不做任何成份
I
love
the
food
that
he
cooks.
这句中的that在从句中做宾语成份
其他的名词性从句的连接词是要做成份的。
I
don't
know
why
she
did
not
come
last
night.
why在从句中做状语
Do
you
know
who
will
teach
us
English?
who
从句中做主语
定语从句中的引导词叫关系词，根据它们的词性，分别叫关系代词和关系副词；名词性性从句的引导词叫连接词，分别叫连接代词和连接副词。
