Answer:
El mes pasado fui con mis amigos de campamento. Llevamos una carpa y dormimos cuatro noches seguidas allí. Luego, el quinto día, descubrí un animal peligroso suelto. Nos fuimos inmediatamente. A pesar de ese inconveniente, nos divertimos mucho.
Explanation:
I wrote an example of a text describing a past trip and using only the preterite tense. The Spanish preterite tense ("pretérito perfecto simple" in Spanish) is used to talk about actions completed at some point in the past.
"Fui" and "nos fuimos" are the preterite form of the irregular verb "ir" and "llevamos", "dormimos", "descubrí" and "divertimos" are regular preterite verbs. I also used the phrases "el mes pasado" and "luego".
