Hello, I'm Sam and in this lesson
we're going to look at the differences between
'at', 'in' and 'on' for location.
'At' can be used to talk about a single specific location.
I'm at work.
Or: I'm at the BBC right now.
'On' is used in relation to a surface.
I'm sitting on a chair.
And 'in' is used to talk about a three-dimensional space,
usually with four walls.
It's similar to 'inside'.
I'm in a room.
So to help you remember these rules,
try to think of a concert:
I'm at the front.
The band is on the stage.
And my friends are in the crowd.
And where are you right now?
