宾语从句引导词

Question

如题所述

Answer 1

宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。
1.
由that引导的宾语从句。that只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。例如：
He
said
(that)
he
wanted
to
stay
at
home.
She
doesn't
know
(that)
she
is
seriously
ill.
2.
由连接代词who,
whom,
whose,
what,
which和连接副词when,
where,
why,
how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：
Do
you
know
who
(whom)
they
are
waiting
for?
He
asked
whose
handwriting
was
the
best.
Can
you
tell
me
where
the
No.3
bus
stop
is?
I
don't
know
why
the
train
is
late.
3.
由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。例如：
I
want
to
know
if
(whether)
he
lives
there.
He
asked
me
whether
(if)
I
could
help
him.
