用法筆記

Separable — the object can go between the verb and particle: 'power the computer off' or 'power off the computer.' Also used intransitively when the device itself is the subject: 'The screen powered off.' Typically used for electronic devices with a power mechanism; not natural for mechanical items or simple lights.

常見錯誤

I turned off the light before bed.
'power off' is for devices with a power button or mechanism; lights are 'turned off' or 'switched off.'
