Explanation:
1. <em>"El agente de viajes"</em> is the travel agent, the one who confirms the reservation.
2. <em>"La estación de autobuses"</em> is the bus station, as an example you could say that the bus station has a dirty floor.
3. <em>"Hacer un viaje"</em> means take a trip. So you could say "In summer we will take a trip."
4. "Pescar" means to fish. So you could say "I want to fish in the sea." Then "paisaje" means landscape. So you could say "Galilea has a beautiful landscape" or "the passangers are waiting to take pictures of the landscape."
