Is the time Sheila joined the Sierra Club the same or different? • Sheila has joined the Sierra Club. • Sheila joined the Sierra Club. The use of the present perfect has more to do with our present perspective on the event rather than on the actual time at which it took place.
Present Perfect or Simple Past? • The simple past tense occurs with specific past-time adverbials. The use of specific past-time adverbials (e.g., yesterday, last year, 1990) makes the past tense obligatory. The use of more general temporal adverbials is commonly associated with the perfect (e.g. already, since, yet).
