1.
'You helped' is in the past simple, not in the imperfect past; it is not the requested tense.
'You (plural) helped' is second person plural, but the subject is 'I', so it does not agree.
2.
'Went' is first or third person singular, it does not agree with 'we'.
'Went' is second person singular, it does not agree with 'we'.
3.
'Were working' is third person plural, it does not agree with the implicit 'you' in the question.
'Were working' is second person plural, it does not agree with the implicit subject 'you' in the question.
4.
'You were' is second person singular, it does not agree with 'they'.
'We were' is first person plural, it does not agree with the subject 'they'.

Understanding the Imperfect Past Tense with Irregular Verbs in Spanish

This lesson focuses on the use of the pretérito imperfecto (imperfect past tense) for three essential irregular Spanish verbs: ser (to be), ir (to go), and ver (to see). The imperfect tense in Spanish is used to describe ongoing, habitual, or repeated actions in the past, as well as background settings or descriptions.

Key Verbs and Their Imperfect Forms

  • Ser: era, eras, era, éramos, erais, eran
  • Ir: iba, ibas, iba, íbamos, ibais, iban
  • Ver: veía, veías, veía, veíamos, veíais, veían

Examples in Context

Here are sample sentences using these verbs in realistic emergency service settings to demonstrate their use:

  • Yo era voluntario en la Cruz Roja.
  • ibas al centro médico en bici.
  • Ella veía pacientes graves a diario.
  • Nosotros éramos responsables del teléfono de emergencia.
  • Vosotros ibais con la Cruz Roja.
  • Ellos eran voluntarios muy buenos.

Important Notes on Usage

These irregular verbs do not follow the standard pattern of regular imperfect tense conjugations. Ser changes to era and its variants, ir adopts iba forms, and ver integrates an additional i to form veía and its variations. It is crucial to memorize these conjugations for correct use.

Differences Between English and Spanish in Expressing the Imperfect

English often uses the past continuous or phrases like "used to" to express repeated or ongoing past actions, while Spanish uses the imperfect tense directly. For instance, "I was going" or "I used to go" corresponds to yo iba in Spanish. Similarly, "I saw" in an ongoing sense is yo veía, differing from the simple past vi used for one-time completed actions. This lesson highlights these essential forms for better fluency and understanding.

Useful Phrases

  • Yo era voluntario - I was a volunteer
  • Tú ibas al hospital - You used to go to the hospital
  • Ella veía ambulancias - She was seeing ambulances
