Do I need to use the preferir or imperfect form of nadar for this?

Todos los veranos Juan _en el mar. (nadar)

The correct answer is, Todos los veranos Juan nada en el mar.

Explanation:

This is because you aren't talking about yourself or anyone else in the past. Juan is swimming in the present, for example, you were there at the beach with a friend and you tell your friend what Juan is doing. You would say Juan is swimming in the ocean.

the ecuadorians are more hard working people and word from early sun raise until sunset. then you join with family for dinner and talk about their day. while in america it’s different. everyone live and have different rules and traditions habits.
