宾语从句造句，陈述句，一般疑问句，特殊疑问句

Answer 1

1.
一般疑问句改成宾语从句时，先在从句前加上if/whether，然后把它变成陈述句序即可，当然也要注意时态的变化和some/any的变化。
如：Can
you
play
football?

→
I
don't
know
if/whether
you
can
play
football.
2.
陈述句改成宾语从句时，先在从句前加上that（也可以不加），照抄即可，当然也要注意时态的变化。
如：She
is
a
student.
→
He
said
(that)
she
was
a
student.
3.
特殊疑问句改成宾语从句时，疑问词不变依然放在从句句首，其后变成陈述句序，当然也要注意时态等变化。
如：How
old
is
he?
→
I
wanted
to
know
how
old
he
was.
