The present perfect tense refers to an action or state that either occurred at an indefinite time in the past (e.g., we have talked before) or began in the past and continued to the present time (e.g., he has grown impatient over the last hour). The exact time is not important.

O tempo present perfect se refere a uma ação ou estado que ocorreu em um tempo indefinido no passado (por exemplo, we have talking before) ou começou no passado e continuou até o tempo presente (por exemplo, he has grown impacient over the last hour). O tempo exato não é importante.

We use the present perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc.
