The Present Perfect tense is a rather important tense in English, but it gives speakers of some
               languages a difficult time. That is because it uses concepts or ideas that do not exist in those
               languages. In fact, the structure of the Present Perfect is very simple. The problems come with
               the use of the tense. In addition, there are some differences in usage between British and
               American English.
