Answer:
A complete present-tense sentence using the subject and verb combination given could be:
- <em>Los estudiantes </em><u><em>aprenden</em></u><em> de memoria las fórmulas matemáticas.</em>
- <em>Julio </em><u><em>sabe</em></u><em> escoger sus amistades.</em>
Explanation:
The translation of the sentences is:
- Students <u>memorize</u> mathematical formulas.
- Julio <u>knows</u> how to choose his friendships.
The Present Tense in Spanish has the order below:
- Noun + conjugated verb + complement.
How the verbs used in the sentence are <em>"aprender"</em> and <em>"saber,"</em> I'll show you the right conjugation of those verbs in Present Tense:
- <em>Yo </em><em>aprendo/sé.
</em>
- <em>Tú </em><em>aprendes/sabes.
</em>
- <em>Usted </em><em>aprende/sabe.
</em>
- <em>Él </em><em>aprende/</em><em><u>sabe</u></em><em>.
</em>
- <em>Ella </em><em>aprende/sabe.
</em>
- <em>Ello </em><em>aprende/sabe.
</em>
- <em>Nosotros/Nosotras </em><em>aprendemos/sabemos.
</em>
- <em>Ustedes </em><em>aprenden/saben.
</em>
- <em>Ellos/Ellas </em><em><u>aprenden</u></em><em>/saben.
</em>
As the first noun <em>"los estudiantes"</em> can be replaced by the personal pronoun <em>"Ellos,"</em> the right conjugation of the verb is <u><em>"aprenden,"</em></u> in another hand, how the second noun is <em>"Julio"</em> and can be replaced by the personal pronoun <em>"Él,"</em> the right conjugation is <u><em>"sabe."</em></u>
