Answer:
The correct forms of the verbs using the combination of "ir + a + infinitive" is:
- <u><em>Voy, vamos</em></u>.
- <em>Esta tarde </em><em><u>voy</u></em><em> a salir de compras porque necesito un traje de baño para mis vacaciones. Necesito comprarlo hoy porque mis amigas y yo </em><em><u>vamos</u></em><em> a ir a la playa mañana por la tarde.</em>
Explanation:
The translation of the paragraph is:
- This afternoon I <u>am going</u> to shop because I need a swimsuit for my vacation. I need to buy it today because my friends and I <u>are going</u> to go to the beach tomorrow afternoon.
The verb <em>"ir"</em> in Present Tense is modified by the personal pronoun used, the possible conjugations can be:
- <em>Yo </em><u><em>voy</em></u><em>.</em>
- <em>Tú </em><em>vas</em><em>.</em>
- <em>Él </em><em>va</em><em>.</em>
- <em>Ella </em><em>va</em><em>.</em>
- <em>Ello </em><em>va</em><em>.</em>
- <em>Nosotros </em><u><em>vamos</em></u><em>.</em>
- <em>Ellos </em><em>van</em><em>.</em>
<u>The appropriate form is identified using the personal pronoun that appears or replacing the noun with the personal pronoun that applies</u>, In the first case, the personal pronoun is <em>"yo"</em> so the correct conjugated form is <em><u>"voy"</u></em>, in the second case, the noun is <em>"mis amigas y yo"</em> that could be replaced by the personal pronoun <em>"nosotros"</em> or "we" in English, so the correct conjugated form is <u><em>"vamos</em></u>."
