Question

如何判断一个句子是宾语从句还是定语从句还是名词性从句

Answer 1

宾语从句就是整个从句做宾语，如I
don't
know
what
is
right.
句中
what
is
right就是宾语从句。
定语从句就是整个从句做定语，修饰一个名词。
如I
don't
know
the
boy
who
is
very
homesome.句中who
is
very
homesome是修饰the
boy
的。

Answer 2

顾名思意，修饰宾语的从句是宾语从句，如：I
know
a
person
who
is
very
kindly.
person在主句当中作宾语，后面who引导的从句是宾语从句
定语从句的主要作用
是修饰限定主语，如，He
that
is
carelss
forgot
to
turn
off
the
light
that
is
careless
修饰he，引导的是定语从句
名词性从句字的是可以充当名词的从句或者是起到名词作用的从句，如，who
was
speaking
loudly
will
stand
all
day
long!
