Life Experience
Present Perfect
Use the present perfect when speaking about an experience that has happened before the present moment when the time of the event remains unspecified.
Example:
Have you asked the women in the housekeeping department?
They've requested wake-up calls in hotels all around the world.
They haven't had the chance to streamline the process for ticket purchases.
In this case, the present perfect is used to express an experience without giving precise details. Whenever you speak about something that has happened up to now without giving a precise point in time, use the present perfect.
Positive Form:
I've travelled on fourteen major highways in the United States.
Negative Form:
They haven't had the chance to streamline the process for ticket purchases.
Question Form:
Have you asked the women in the housekeeping department?
'Ever' and 'Never' with the Present Perfect
Use the present perfect with both 'ever' and 'never'. These time expressions are often used to to discuss experiences.
She has never tried gourmet coffee.
She has never tolerated disgruntled employees.
Place 'ever' or 'never' directly before the past participle in the question form.
Have you ever thought about how leisure time reinforces labor time?
Have they ever thought about setting a budget?
'Never' means 'not ever' and is a negative form of the present perfect.
