Choosing the Right Past Tense in a Class Presentation
A Year 11 beginner Spanish student, Mei, is preparing a two-minute oral presentation about her last holiday for a SACE Stage 2 beginners class. She wants to describe three past events: (1) a single completed trip to the beach on Saturday, (2) the weather during the whole week, and (3) a habit she had when she was younger of visiting her grandmother every Sunday. Her teacher has told her the class is focusing on the difference between the preterite and the imperfect. Mei has drafted three sentences but is unsure which tense to use for each event. She also wants to include one sentence about what she was doing when something else happened. Her presentation must be accurate and she has one rehearsal left before the assessment.
1. For each of the three past events, identify which Spanish past tense Mei should use and explain why.
Read the worked answer
Event (1), a single completed trip on Saturday, requires the preterite because it describes a one-off, finished action with a clear endpoint: El sábado fui a la playa. Event (2), the weather during the whole week, requires the imperfect because it describes an ongoing background condition without a defined endpoint: Hacía buen tiempo toda la semana. Event (3), a repeated habit in the past, also requires the imperfect because habitual actions are expressed with the imperfect: Cuando era joven, visitaba a mi abuela todos los domingos. The key distinction is boundedness: the preterite frames an event as completed, while the imperfect frames it as ongoing, habitual, or background.
2. Mei also wants a sentence meaning 'I was swimming when I saw a dolphin.' Which tense should each verb take, and why?
Read the worked answer
Use the imperfect for the ongoing action (nadaba) and the preterite for the interrupting event (vi): Nadaba cuando vi un delfín. The imperfect presents the action in progress as background, while the preterite presents the event that interrupts or completes it. This combination is the classic 'imperfect + preterite' structure. If Mei reversed the tenses, the meaning would shift: Nadé cuando vi un delfín would suggest two completed events in sequence rather than one action interrupted by another.
