change into present perfect tense

Simple Present tense: She brings a carpet.  MEANING: she regularly or routinely does this. (It would be a very unusual situation for someone to regularly bring a carpet somewhere.)

Simple Past tense: She brought a carpet. MEANING: she did this in the past.

Present Perfect tense:  She has brought a carpet.  MEANING: she did this in the past, and this fact, this past event, is important now.

It is unusual to need to change a Simple Present tense to Present Perfect, because there is such a big difference in meaning.

I hope this helps.  Let me know if you have any other questions.
