you,
Id
take
them
away.
如果我是你的话，我就会带走他们。

有关虚拟语气的几个问题
1)
有时if引导的状语从句可以省略
if，而把从句中的动词
were,
had
或
should
移到主语前面。
Were
she
younger,
she
would
do
it
.
如果她年青点，
她就会干的。
Had
he
known
her
address,
he
would
had
gone
to
visit
her.
如果他知道她的地址，他会去看她的。
2)
有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个主句或者一个条件从句。
I
could
help
you.
我本来可以帮助你。
If
I
had
time.
我要有时间该多好啊!
She
should
have
come
to
the
party.
她应该来参加聚会。
If
he
had
much
more
money.
如果他有更多的钱就能...。
3)
虚拟语气中，条件从句的动词动作可以和主句的动词动作时态不一致。
If
they
had
studied
hard,
they
could
do
it
easily
now.
如果他们以前努力学习的话，现在干的就会容易些。
If
he
had
not
taken
my
advice,
he
wouldnt
do
it
much
better
like
this.
如果他不听取我的建议，他就不会干得这样好。
