一般动词介词之后是宾语从句
名词之后是定语从句
定语从句是对先行词起到修饰作用的从句，简单的说就是形容词
宾语从句相当于宾语，只是因为宾语很长或宾语以一个句子的形式出现的
看下面两个句子
He
told
me
that
you
were
stupid.
这里that
you
were
stupid放在了told
me
的后面，而tell
me后面本该加名词的，而这个名词作宾语；that
you
were
stupid就代替了这个名词，因为是个句子，所以这个句子教宾语从句
He
is
a
student
that
is
hardworking.他是个勤奋的学生
that
is
hard
working相当于形容词，只是把形容词放在了student的后边来修饰它了
定语从句是相当于形容词，用来修饰名词的，一般是位于名词后面，只不过是一个句子而不是一个词。
宾语从句是做宾语的，一般是在动词或者介词后面
he
is
a
boy
who
likes
swimming.他是一个（喜欢游泳的）男孩。，修饰boy
he
don't
know
that
his
friend
is
ill.这是宾语从句，做know的宾语
定语从句作定语,修饰名词,有先行词(定语所修饰的词):而宾语从句作宾语,没有先行词
定语从句接在名词或代词的后面
宾语从句接在动词或介词的后面
There's
nothing
that
I
can
do.
I
don't
know
that
he
is
from
USA.
定语从句没有what
宾语从句有what
