Answer:
3. No vayas a comer
3. No vayas
4. Dice
5. Se generoso con tu tiempo y no un antipático
7. Apagues
Explain:
3. In the first missing the verb ''ir'', so the correct answer is: No vayas a comer.
3. It is not ''no comas'' the correct answer is: No vayas (by the logic of the sentence).
4. It is not ''Se dice'', it is only ''Dice'' because the ''se'' is unnecessary to write it in this case.
5. By the logic of the sentence, you don't put ''yo'', it's: Se generoso con tu tiempo, y no un antipático.
7. It's okay, but missing the ''u'', so the correct answer is: apagues.
