Answer:
The right conjugation that fills the blanks in the sentences is:
- <em>Josefina </em><em><u>se lava</u></em><em> las manos en el lavabo. Josefina </em><em><u>lava</u></em><em> </em><em>la ropa en casa de su madre.</em>
- <em><u>Peino</u></em><em> a mi hermana todas las mañanas. </em><em><u>Me peino</u></em><em> en el baño, delante del espejo.</em>
- <em><u>Nos ponemos</u></em><em> nerviosos antes de un examen. </em><em><u>Ponemos</u></em><em> la toalla al lado de la ducha.</em>
- <em>Los estudiantes </em><em><u>se levantan</u></em><em> </em><em>muy temprano. Los estudiantes </em><em><u>levantan</u></em><em> </em><em>la mano y hacen preguntas.</em>
Explanation:
The translation of the sentences is:
- Josefina <u>washes</u> her hands in the sink. Josefina <u>washes</u> clothes at her mother's house.
- I <u>comb</u> my sister every morning. I <u>comb</u> my hair in the bathroom, in front of the mirror.
- We <u>get</u> nervous before an exam. We <u>put</u> the towel next to the shower.
- The students <u>get up</u> very early. The students <u>raise</u> their hands and ask questions.
In Spanish you can find pronouns objects (<em>me, te, se, nos, le</em>) when the action is focused on the same individual who performs it (bathing himself, lifting himself, combing himself) while if the action is performed for the benefit or focused on another person, the verb conjugates normally, in this case, in Present Tense.
Below I show the use of the object pronouns depending on the personal pronouns:
- <em>Yo: </em><u><em>me</em></u><em>.</em>
- <em>Tú: </em><u><em>te</em></u><em>.</em>
- <em>Nosotros: </em><u><em>nos</em></u><em>.</em>
- <em>Usted/Ustedes/Él/Ella/Ello/Ellos/Ellas: </em><u><em>se</em></u><em>.</em>
Finally, you only have to change the noun to the appropriate personal pronoun and use the corresponding object pronoun.
