Sentence corrections (From the present tense into the imperfect tense)

Question

I'm working out of a study book which have given a few sentences written in spanish. The instructions are to change the verbs from the present tense to the imperfect tense.. Please can someone give corrections. Thanks

(a) Los domingos si hace buen tiempo doy un paseo en el parque.
Los domingos si hacía buen tiempo daba un paseo en el parque.

(b) Mientras los demás trabajan, tú charlas.
Mientras los demás trabajaban, tú charlabas

(c) Por la noche ven la tele y se acusetan tarde.
Por la noche venía la tele y se acuestaban tarde.

Answer 1

thank you Lazarus and Natasha.

Answer 2

Lazarus, am I right about the rule for stem-changing verbs?

You are right, but you can make your rule even more general, since the imperfect tense is one of the most regular ones in Spanish: only the verbs "ir", "ser" and "ver" (and similar ones) have an irregular imperfect.

The only mistakes are on the conjugation of "ver" and "acostarse"; everything else is fine:(c) Por la noche ven la tele y se acuestan tarde.Por la noche veían la tele y se acostaban tarde.

Oops, I missed that one! It seems we have mixed up ver and venir! I'm glad Lazarus fixed it! Lazarus, am I right about the rule for stem-changing verbs'

Answer 4

The only mistakes are on the conjugation of "ver" and "acostarse"; everything else is fine:

(c) Por la noche ven la tele y se acuestan tarde.
Por la noche veían la tele y se acostaban tarde.

Answer 5

For the last one, I believe it should be se acostaban. Stem-changing verbs don't change the stem for the imperfect tense (I think). See the conjugation tool if you like. The rest looks great . . . we'll see if anyone else has any improvements to suggest.
