The passive

Adding an s

If present tense ending in r, then + r s
- öppnar -> öppnas
If present tense ending in er then usually the whole ending disappears
- köpper -> köps
- köpper -> köpes (more formal)

Or one can use blev / vara / är + past participle to do the same:

Bilen blev reparerad, medan vi väntade (The car was repared while we waited)
Bilen reparerades, medan vi väntade.
Villan är redan såld. (The house is already sold)
Villan har redan sålts.

Two Participle from - 两种分词形式

present participle (presens particip)
past participle (perfekt particip)

The participles can be used in the same way as adjectives:

en läsande pojke (present) - a reading boy
en stängd dörr (past) - a closed door
