Answer:
1. ¡Ven aquí!
2. ¡Sal a las siete!
3. ¡No salgas ahora!
Explanation:
In English these sentences mean:
Come here!
Go out at seven!
Don't go out now!
Imperative in Spanish is used to give orders or commands. If the verb is regular it is conjugated in the third person singular of the present. However some verbs are irregular and have a special use in the imperative. That's the case of the verbs "venir" and "salir" which are both in this exercise.
Venir is conjugated affirmatively as "ven" and negatively as "no vengas".
Salir is conjugated affirmatively as "sal" and negatively as "no salgas".
