PABLO No, (7) <u>pienso</u> (pensar) que vamos a (8) <u>perder</u> (perder). Los jugadores de Guadalajara son salvajes (wild) cuando (9) <u>juegan</u> (jugar).
Explanation:
To complete this exercise, you have to complete the conversation between Pablo and Oscar with the correct stem-changing verbs.
<u>Stem-changing verbs</u> are verbs that in the present tense have a vowel change in the last syllable of the steam. There are different ways the stem-changing verbs can change:
e changes to ie
o changes to ue
e changes to i
i changes to ie
u changes to ue
<u>For example</u>, the first verb you have to change is "pensar" (e), so it changes to "pienso" (ie). <em>"Pens"</em> is the stem and <em>"piens" </em>the stem change.
