Final answer:
To fill in the blanks for the verb recibir in the first person, use 'recibo' for 'yo' and 'recibimos' for 'nosotros/as', which translates to 'I receive' and 'we receive' respectively.
Step-by-step explanation:
The question is asking to fill in the blanks with the correct form of the verb recibir (to receive) in Spanish. In Spanish, verbs are conjugated according to the subject pronoun and tense. Here, we need the present indicative tense for the first person singular (yo) and the first person plural (nosotros/as).
The conjugation for the first person singular (yo) is recibo. This means 'I receive.' For the first person plural (nosotros/as), the conjugation is recibimos. This means 'we receive.' Therefore, the sentences filled correctly would be: 'yo recibo' and 'nosotros/as recibimos'.
These forms are the same for all regular -ir verbs in the present tense in Spanish, with the endings being -o for yo and -imos for nosotros/as. Other regular -ir verbs would follow this same pattern of conjugation.
