His car is dirty.
- He is washing his car.
- He has washed his car.
( = his car is clean now)
- They are at home.
- They are going out.
- They have gone out.
( = they are not at home now)
B. We use the present perfect (he has washed / they have gone, etc.) for an action in the past with a result now.
- I’ve lost my passport. ( = I can’t find my passport now)
- “Where’s Tiffany?” “She’s gone to bed.” ( = she is in bed now)
- We’ve bought a new car. ( = we have a new car now)
- Rachel has a headache because she hasn’t taken her medicine.
- “Bob is on vacation.” “Oh, where has he gone?”
- Have you met my brother, or should I introduce you?
- I was a very slow typist in college, but I’ve gotten faster.
Usually you can also use the simple past (he washed / I lost, etc.) in these situations. SO you can say:
- “Where’s your key?” “I’ve lost it.” Or “I lost it.”
- “Is Peter here?” “No, he’s gone home.” Or “He went home.”
- We’ve bought a new car. Or We bought a new car.
C. We use only the simple past (not the present perfect) with a finished time (yesterday, last week, etc.).
- I lost my key yesterday. (not I have lost)
- We bought a new car last week. (not we have bought)
