1) Marta se levanta y después se viste. In order to fill in the correct word you just have to know the translation of each one. With the word ‘después’ the complete sentence makes sense, as it is translated as “ Marta gets up and then gets dressed.”
antes - before
durante - during
2) Alfonso se ducha en el gimnasio. Alfonso takes shower in the gym. Here you can see the verbs that are not similar semantically at all, so you just need to pick the one which logically suits best. Since se duerme- falls asleep and se acuesta-lies down, then se ducha is the answer.
3) Carla se cepilla el pelo. Carla brushes her hair. The verb ‘se cepilla which’ is ‘to brush’ is the best one to use with the direct object ‘hair’. Other options contain actions which cannot be performed upon object in a sentence. (‘to make up’ and ‘to wake up’)
4) Por la mañana me levanto, me ducho y por último. Here you have to choose the correct adverb of time again. As you can see, the speaker is telling us about his schedule, naming actions in a set order. Since there is a gap before the last action, you have to put ‘por último’ which is ‘finally’ to complete the sentence. In the morning I get up, take a shower and finally dress up.
5) Cuando salgo de la ducha, me pongo las pantuflas ---> When I get out of the shower, I put on the slippers. There you have a situation, so you have to pick an object that fits in it. Of course, ‘las pantuflas’ is the only suitable object regarding the context.
6). José se ducha por la noche. Joseph takes shower in the evening. Ducharse (in english is to take a shower, or to shower oneself) is a regular verb, and its form for third person singular in present tense is se ducha.
7). Mi hermana y yo nos levantarse a las siete de la mañana. Me and my sister get up at seven in the morning. Now we have a plural pronoun (Mi hermana y yo = we) so the verb form in present tense is nos levantarse.
8).Yo me pongo los zapatos nuevos. I put on new shoes. The spanish verb ‘ poner’ means to put on or to wear. The pronoun of the sentence is the first person singular, so its present form is pongo.
9) .Mis padres nunca se enojan con mi hermana. → My parent never get angry with my sister. The verb enojarse is a regular verb which means to get angry, get upset. Here it is used with third person plural pronoun, so its present form changes into se enojan. Keep in mind that in you want to say ‘to anger or to make [someone]angry’, you have to use the non reflexive form enojar.
10) ¿ Tú te sientes bien? → Do you feel well? This question contains a verb that describes feelings, and in Spanish it can be quite tricky sometimes. For second person singular pronoun this verb in present is ‘ te sientes’. Pay attention! Here this verb is used intransitively with adjectives, if you want to use it the sense of to feel, regretyou have to use non reflexive form - sentir.
11) ¿Adónde ir tú después de la clase de español? In order to insert the correct verb you have to make sure that you translated it right (because this two verbs are completely different and you have to understand the context). This sentence means ‘Where did you go after the Spanish class?". Therefore, we have to use the infinitive is "Ir" that translates as ‘to go’12) Marcos y Silvia erais novios por dos años. Marcos and Silvia were lovers for two years. The verb to be is needed here, and for spanish it is “ser”. But since it is a past tense, the form of this verb changes into erais - as it is imperfect tense for second person pronoun in plural.
13) Yo fui al baño de la biblioteca. ---> I went to the library restroom. There is a verb of direction, so it is ‘ir’. And since we are talking about the past tense of the first person singular, the verb form changes into ‘fui’.
14) Usted fue el responsable, ¿verdad? The translation is : "You're the responsible; aren't you!?" The verb ‘to be’ is used to the infinitive is ‘ser’. With the second person singular this verb changes into ‘fue’.
15) 5. Nosotras fuimos a Argentina el año pasado --> "We went to Argentina last year". Another example of direction verb ‘to go’, so the infinitive is "Ir". The verb form for first person plural in the past is fuimos.
