<u>Reflexive verbs</u> are transitive verbs whose action falls on the same subject that performs them. In other words, they refer to an action of a subject on itself.
They are used together with <u>reflexive pronouns</u>, which are shown below according to the personal pronoun used:
1st person singular Yo (I): me
2nd person singular (informal) Tú (You): te
2nd person singular (formal) Usted (You): se
3rd person singular Él/Ella/eso/esa (He/She/It): se
1st person plural Nosotros (We): nos
2nd person plural Ustedes (You) (In latinAmerica): se
2nd person plural Vosotros (You) (In Spain): os
3rd person plural Ellos/Ellas (They): se
Generally, the way they are written in the sentence is (1):
<h2>(1) Personal Pronoun + Reflexive pronoun + conjugated verb</h2><h2 />
Nevertheless, in Imperative the reflexive pronouns are placed at the end of the verb (2):
<h2>(2) Personal Pronoun + conjugated verb + Reflexive pronoun </h2>
Knowing this, let's begin with the answers:
1. Mi mamá <u>se enoja</u> porque no queremos <u>levantarnos</u> temprano.
(My mom gets angry because we do not want to get up early)
The first verb <em>enojar</em> (to get angry) is an example of <u>the first case</u>, in which <u>the reflexive pronoun is written before the verb</u>, taking into acount that <em>Mi mamá </em>is the 3rd person singular <em>ella</em> (she), and the corresponding reflexive pronoun is <em><u>se</u></em>.
The second verb <em>levantar</em> (to wake up) is an example of <u>the second case</u>, in which <u>the reflexive pronoun goes after the verb</u>, taking into account the Tacit Subject here is <em>nosotros</em> (we), hence the reflexive pronoun is <em>nos</em>.
2. La profesora <u>se enoja</u> con nosotros cuando no <u>nos acordamos</u> de los verbos.
(The teacher gets angry with us when we do not remember the verbs)
The first verb <em>enojar</em> (to get angry) is an example of <u>the first case</u>, in which <u>the reflexive pronoun is written before the verb</u>, taking into acount that <em>La profesora </em>is the 3rd person singular <em>ella</em> (she), and the corresponding reflexive pronoun is <em><u>se</u></em>.
The second verb <em>acordarse</em> (to remember) is an example of <u>the second case</u>, in which <u>the reflexive pronoun goes after the verb</u>, taking into account the Tacit Subject here is <em>nosotros</em> (we), hence the reflexive pronoun is <em>nos</em>.
3. Mi hermano <u>se cepilla </u>los dientes cuando <u>se levanta</u>
(My brother brushes his teeth when he gets up)
Here both verbs <em>cepillar</em> (to brush) and <em>levantar </em>(wake up) are an example of <u>the first case</u>, in which <u>the reflexive pronoun is written before the verb</u>, taking into acount that <em>Mi hermano </em>is the 3rd person singular él(he), and the corresponding reflexive pronoun is <em><u>se</u></em>.
4. Mis amigas y yo <u>nos quedamos</u> estudiando en la biblioteca por la noche y por la mañana yo <u>me duermo</u> muy cansada.
(My friends and I stayed in the library at night and in the morning I fall asleep very tired)
Here both verbs <em>quedarse</em> (to stay) and <em>dormir </em>(to sleep) are an example of <u>the first case</u>, in which <u>the reflexive pronoun is written before the verb</u>, taking into acount that the Tacit Subject <em>nosotras </em>is the 1st person plural <em>we</em>, and the corresponding reflexive pronoun is <em><u>nos</u></em>.
With the verb dormir, the Tacit Subject <em>yo</em> is the 1st person singular I, therefore the corresponding reflexive pronoun is <em><u>me</u></em>
5. Muchas noches <u>me duermo</u> delante del televisor, porque no quiero <u>acostarme</u>
(Many nights I fall asleep in front of the television, because I do not want to go to bed)
The first verb <em>dormir</em> (sleep) is an example of <u>the first case</u>, in which <u>the reflexive pronoun is written before the verb</u>, taking into acount that the Tacit Subject<em> Yo </em>is the 1st person singular <em>I</em>, and the corresponding reflexive pronoun is <u><em>me</em></u>.
The second verb <em>acostar</em> (to lie down or go to bed) is an example of <u>the second case</u>, in which <u>the reflexive pronoun goes after the verb</u>, taking into account the Tacit Subject here is <em>yo</em> (I), hence the reflexive pronoun is <u><em>me</em></u><u>.</u>
