Describes how, through the use of two diagrams, one can teach the English present-perfect to Iranian students. One diagram consists of a time-line divided into "past" and "non-past." The other uses an oval to indicate a time-span including the present. Both facilitate comprehension of present-perfect meaning. (PJM)
