If I felt ill I would go to the doctor.
if I witnessed a crime I would call the police
if I got up at ten o'clock I would be late for school
if I saw a ghost I would feel frightened.
I would buy a big house if I had more money.
if I did not have classes today I would go to the cinema.
If we passed the tests our teacher would be happy.
the world would be better if there was less air pollution.
If you got a bad mark I would be very surprided.
I were famous I would have a lot of admirers.
