Answer 1

Complete the sentences with present perfect forms.

1. The boy is eating an ice cream, but he has finished  (not finish) it yet.​

El present perfecto form se estructura de la siguiente forma:

El "present perfect" de cualquier verbo está compuesto por dos elementos: la forma apropiada del verbo auxiliar to have/has (en presente) y el "past participle" del verbo principal. La forma del "past participle" de un verbo regular es raíz+ed, e.g. played, arrived, looked.

Este caso se le agrega ed porque es un verbo regular.
