Along, Past, and Through
Use 'along' to follow the length of something linear, 'past' to move beyond a point without stopping, and 'through' to move inside a three-dimensional enclosed space.

Show answer
past
'Past' for going beyond a place without entering — the 'without stopping' makes this clear.
Along, Past, and Through: Following, Passing, and Entering
'Along', 'past', and 'through' each describe a distinct relationship between a moving body and the space around it. 'Along' describes movement that follows the length or course of something linear — a river, a road, a beach, a corridor. 'Through' describes movement inside a three-dimensional space that encloses the mover on more than one side, such as a tunnel or a forest, entering at one end and exiting at the other. 'Past' describes movement that continues beyond a reference point without stopping there or entering it. These three prepositions are frequently confused because all three can follow verbs of motion in similar sentence positions, and because none of them implies arrival at a fixed destination the way 'to' or 'into' does.
Along — Following the Length of Something Linear
We walked along the beach for two hours, collecting shells. (following the shoreline)
Through — Moving Inside an Enclosed Space
She walked nervously through the dark forest, hearing strange sounds. (the forest surrounds her on all sides)
Past — Moving Beyond a Point Without Stopping
We walked past the bakery without stopping, even though it smelled delicious. ('without stopping' confirms 'past')
Telling Them Apart
Ask three questions in order: Am I following the length of something (along)? Am I enclosed on more than one side while moving (through)? Do I continue beyond this point without entering it (past)? A forest surrounds you on all sides, so it takes 'through', not 'across' or 'along'. A shop you walk by without entering takes 'past'.
