If you put ice into water,
If your mother had been here
If we pass the exams,
We would have finished one hour ago
She would be happier
If they don't come to class,
If I were you
If you didn't have an smartphone,
Unless you do your homework,
If you had told them before,
the students would have joined the activity
it melts
if you had helped us
you won't go out tonight
if she had a nice boss
I would talk to her
they won't get the grant
our parents will buy the concert tickets for us
she would have told you what to do
you wouldn't/couldn't communicate with your friends so frequently
