I had a lot of fun at the beach last year because we played games and drew in the sand. My family and I were really having a great time running around and talking. We ate, fished, cooked, swam in the pool, in the ocean, and did everything we could do!
Something like that... now I'll translate that so you can get a basic idea.
Yo pase muy bien en la playa el año pasado por quw jugamos y dibujamos en la arena. Mi familia y yo lo pasamos bien corriendo y hablando. Comimos, pescamos, cocinamos, nadamos en la pisina y mar, y todo lo que podiamos hacer!
I don’t speak that language. Can you translate? !?
Mis amigos van al museo a ver las pinturas
muchas personas irán a la plaza a divertirse
mis primos fueron al cine
Carlos se arregla para salir a comer, because "se" refers back to Carlos (reflexive).
Hope this helps.
