The alarm will go off at 6 AM
My favorite song just went off on the radio
The milk has gone off; it smells sour
Be careful, that firecracker might go off unexpectedly
The comedian's jokes didn't go off as well as he'd hoped
The fireworks are scheduled to go off at midnight
He warned us that the trap might go off if we weren't careful
The chef tasted the sauce and realized it had gone off
When the bell goes off, the students should leave the classroom
The old clock in the hall goes off every hour with a chime
I heard the alarm may go off soon.
Oh no, I was not expecting that.
Me neither, I hope it is a false alarm.
The alarm will go off at 7 AM
The alarm will sound at 7 AM
The alarm is set to ring at 7 AM
