Focus on the explanations below.1The train travels a long tunnel before reaching the city.Correct answer: through▸ Why?"Through a tunnel" = moving inside and out of a 3D enclosed space. "Through" is used when movement passes within something (a tunnel, a forest, a crowd). "Across" = over a flat surface from side to side; it doesn't fit an enclosed space.2We walked the bridge to get to the other side of the river.Correct answer: across▸ Why?"Across the bridge" = moving from one side to the other over a flat or horizontal surface. "Across" suits flat, open routes like bridges, rivers, and roads. "Through a bridge" would mean inside the structure (e.g., a hollow tunnel-bridge), which is unusual.3She jogged the seafront every morning before work.Correct answer: along▸ Why?"Along the seafront" = moving in a line following the length of something (a road, a river, a wall). "Along" is used when you travel parallel to something rather than across it. "Across the seafront" would mean moving from one side to the other edge.4The children ran the playground three times.Correct answer: around▸ Why?"Around the playground" = following a circular or enclosing path. "Around" (also "round") means moving in a curve or circle, encircling something. "Along the playground" = moving in one direction along the edge only. "Through the playground" = entering and exiting it.5I drive the school every day on my way to work.Correct answer: past▸ Why?"Past the school" = going by it without stopping; it's a point passed on the route. "Past" means movement to a position beyond a reference point. "Along the school" is incorrect (you travel along a road, not a building). "Through the school" = entering and exiting the building.6The path leads the forest and comes out near the lake.Correct answer: through▸ Why?"Through the forest" = entering the forest and exiting the other side (3D path within the trees). "Across the forest" could imply crossing it from one edge to the other on an open surface — less natural when you are inside the trees. "Along the forest" = beside the edge of the forest, not inside.7The swimmer crossed the lake in under two hours.Correct answer: across▸ Why?"Across the lake" = from one shore to the other over the water's surface. "Across" suits flat, open expanses (lakes, deserts, fields, roads). "Through the lake" would mean submerged travel. "Along the lake" = following the shoreline, not crossing.8They cycled the canal for several kilometres before stopping for lunch.Correct answer: along▸ Why?"Along the canal" = following the length of the canal (in parallel). "Along" is used for movement parallel to a linear feature: along a river, along a wall, along a street. "Across the canal" = from one side to the other.9He walked the bakery and the smell of fresh bread made him stop.Correct answer: past▸ Why?"Past the bakery" = passing by it (movement beyond it without entering). "Past" indicates a reference point on the route that is passed. "Through the bakery" = going inside and out. "Along the bakery" is incorrect — "along" goes with roads, rivers, or walls.10The road goes the hill rather than over it.Correct answer: around▸ Why?"Around the hill" = following the curve or edge to avoid going through or over it. "Around" here describes a curved path that bypasses an obstacle. "Through the hill" = a tunnel; "across the hill" = over the flat top; "along the hill" = beside its base.11He pushed the crowd to get to the front of the queue.Correct answer: through▸ Why?"Through the crowd" = moving within a mass of people from one side to the other. The crowd surrounds you (3D) as you move through it. "Across the crowd" is less natural — you are not crossing a flat surface. "Past the crowd" = moving beyond it without entering.12The soldiers crept the wall, keeping out of sight.Correct answer: along▸ Why?"Along the wall" = moving in a line parallel to the wall, following its length. "Along" suits movement next to extended linear structures. "Through the wall" = passing through a solid barrier (physically impossible). "Past the wall" = going beyond one point on the wall.13Always look both ways before running the road.Correct answer: across▸ Why?"Across the road" = from one pavement to the other (perpendicular crossing). "Across" is the standard preposition for crossing flat surfaces. "Through the road" would imply moving within the tarmac. "Along the road" = parallel to the road (not crossing).14The bus goes the cathedral, so you'll recognise the stop.Correct answer: past▸ Why?"Past the cathedral" = the bus travels beyond the cathedral as a reference point on the route (it doesn't stop or enter). "Past" is used as a directional landmark: "go past the traffic lights and turn left." "Through the cathedral" = entering and exiting. "Around the cathedral" = going around it in a curve.15There was a fallen tree in the path, so we had to go it.Correct answer: around▸ Why?"Around it" = following the edge to bypass it without entering or crossing it. "Around" describes the detour that avoids the obstacle. "Through it" = passing within/inside (only possible if the tree were hollow or the obstacle permeable). "Past it" = beyond it — but that implies passing by a side point, not necessarily navigating around it.Check AnswersPlease answer at least one question first.Found an error in this exercise?
