Schließen
(every time for present)
If I drink coffee at night
If the sky is without occasional dark clouds
(for future)
If we pick him up ,
(present or future unreal situation)
If I were at home
If I drank a cup of tea
(for past unreal situation)
If I had done this work yesterday
If am hungry
If I were hungry
If I had been hungry yesterday
If I am thirsty in 5 minutes
If they were busy
