Answer:
Llegué al aeropuerto de Buenos Aires, Argentina.
Quiero conocer el obelisco.
Iré a visitar el glaciar Perito Moreno en avión.
En Mar del Plata hay muchos lobos marinos, puedo tomar fotos de ellos.
Buenos Aires es hermosa, estoy triste de que mi viaje termino.
Explanation:
The appropriate form of the verb arrive to talk in the first person in the past, is llegué followed by the preposition a, and the place.
To indicate that I want to visit a specific place, we have to use the conjugated verb quiero and the correct form to say that I want to know a place is conocer, saber is related to information, and conocer is to explore.
The correct form of the verb ir in the first person of the future is ire +a and the infinitive form of visit, which is visitar.
In sentence number four, the chosen word is hay, to say that there are sea lions and that you can take pictures of them.
In the last sentence, we use the verb es to describe the city of Buenos Aires, so we use the verb es followed by an adjective, in this case, beautiful (hermosa) and we use the first person in the present of the verb estar, which is estoy to talk about our feelings.
