1.
时间状语从句：明天他来时，我会告诉他的。I
will
tell
him
when
he
comes
tomorrow.
2.
条件句：如果明天下雨，我们就呆在家里。
If
it
rains
tomorrow,
we
will
stay
at
home.虚拟语气属于条件句。而真实的条件句都必须用陈述语气。（比如上一句）虚拟语气基本上分三种时间段：1
对过去发生完的事情，埋怨，或猜测。如：如果你不去那里的话，
就不会发生这事情了。If
you
had
not
gone
there,
it
would
not
have
happened.2.
对现在的推测，如：如果我是你的话，我就去那里。If
I
were
you,
I
would
go
there.
3.
对未来推测，如：如果明天地球没有水的话，我们怎么办？What
should
we
do
if
there
should
no
water
on
the
earth
tomorrow?
if
引导的就是条件状语从句，而且你也完全可以根据汉语翻译来辨别。（We
will
go
to
the
zoo【if
it
doesn't
rain
tomorrow.】(主句)【从句】I
don't
know
if
it
will
rain
tomorrow.【这是一个if引导的宾语从句:我不知道明天是否会下雨。】
