Hi Ashkan! To answer your second question to Lucy, we use 'have been to' when we are talking about a completed return trip, and 'have gone to' when the person has not yet returned. So: 'I have been to Italy' (I went there and came back), but 'John isn't here, he has gone to the shops'. For your original question the anwer would be past simple: 'I was in Italy for two years' 'I had been in Italy for two years' is the past perfect and would only be correct if there was a second part to the sentence.

See below for answers: If I was in Italy between 2010 to 2012, which one can be correct? A) I was in Italy for 2 years. B) I had been in Italy for 2 years.

My pleasure
