Answer 1

The
bills
and
coins
（that
we
use
today）
are
known（是这个单词）
as
currency.这句是主语从句么？
括号里的是个定语从句，修饰先行词The
bills
and
coins
，关系代词在从句中作宾语，“我们今天使用的钞票和硬币”
that
is
generally
accepted
in
exchange
for
goods
and
services.
这句是表语从句么？
不是，是个定语从句，修饰先行词an
objective
，关系代词在从句中作主语的。
PS：从句的断定标准：从句在整个句子里作什么成分，它就是什么从句。如：
(What
he
said)
sounds
good主语从句
I
asked
(if
he
was
a
student)宾语从句
My
advice
is
(that
he
go
home
now)表语从句
The
book
(whose
cover
is
green)
is
a
dictionary定语从句
(Wherever
you
go,
and
whatever
you
do,)
i
will
be
right
here
waiting
for
you.状语从句
