WHERE HAVE YOU BEEN?

EN ESTE VÍDEO PODÉIS ESCUCHAR UNA CANCIÓN DE RIHANNA, EN LA QUE SE UTILIZA PRESENT PERFECT EN INTERROGATIVA

LIKE: VERB OR PREPOSITION?

Like as a verb is used mainly to talk about enjoyment, preferences and habits. It is perhaps not quite as strong in emotional terms as love, or be fond of or be keen on. 

Like as a preposition with nouns or pronouns is used to express ideas of similarity or comparison.
