Present Perfect

      Hello guys, today we will study a verb tense that does not exist in Portuguese, the present perfect, bellow we teach the concept, rules and show some examples. Good use!

      As it was said, the present perfect tense is verb tense that has no equivalent in Portuguese. Usually it indicates actions that occurred in the past and still have connections with the present , or shares indeterminate past actions and actions recently completed.

      In relation to syntactic structure, the present perfect is a time composed of two verbs: one main and one auxiliary. The auxiliary is the verb to have (simple present), ie: have (for: I, you, we, They) or has (for: he, she, it). The main verb should always be in the participle.

Ex: Subject + auxilliar verb have (on present) + main verb on participle + complement
Following the example:
I + have + lived + in Australia for 12 years.
