His car is dirty.
- He is washing his car.
- He has washed his car.
( = his car is clean now)
- They are at home.

- “Bob is on vacation.” “Oh, where has he gone?”

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)
