Att använda passiv röst med modala hjälpverb i olika tempus

Använda passiv röst med modala hjälpverb och i olika tempus i engelska

Exempel (aktiv → passiv):
- Active: "Someone stole my bike." → Passive: "My bike was stolen." (Svenska: "Någon stal min cykel." → "Min cykel blev stulen.")
- Active: "Maria writes the letter." → Passive: "The letter is written by Maria." ("Maria skriver brevet." → "Brevet skrivs av Maria.")

Varför använda passiv?
- Agenten är okänd eller oviktig: "My wallet was found." ("Min plånbok hittades.")
- Fokus på handling eller resultat: "The bridge was completed in 2010." ("Bron blev färdig 2010.")
- Formellt eller opersonligt språk: "Mistakes were made." ("Misstag begicks.")
- Instruktioner och skyltar: "No smoking" ↔ "Smoking is not allowed." ("Rökning är inte tillåten.")

Exempel (stegvis):
- Active: "They build houses." → Objekt: "houses" → Passive: "Houses are built (by them)." ("Man bygger hus." → "Hus byggs.")

Observera subjekt–verb-överensstämmelse: verbet be böjs efter det nya subjektet (singular/plural).

Hur fungerar passiv med modala hjälpverb?

modal + be + past participle

Exempel:
- "The window can be opened." ("Fönstret kan öppnas.")
- "The form must be signed." ("Formuläret måste undertecknas.")
- "The rules should be followed." ("Reglerna bör följas.")

Fråga/negation med modal i passiv:
- "Must the form be completed?" ("Måste formuläret fyllas i?")
- "The door must not be opened." ("Dörren får inte öppnas.")

Perfekt modal passiv: modal + have + been + past participle

För handlingar i det förflutna eller när modal uttrycker slutledning om dåtid används:

modal + have + been + past participle

Exempel:
- "The documents must have been signed." ("Dokumenten måste ha blivit undertecknade.")
- "The painting might have been stolen." ("Målningen kan ha blivit stulen.")
- "They should have been informed earlier." ("De borde ha informerats tidigare.")

Skillnad i betydelse:
- "He must be told." = obligation nu ("Han måste få veta det").
- "He must have been told." = slutsats om något som hänt tidigare ("Han måste ha blivit informerad").

Progressiv passiv med modal (sällsynt): modal + be + being + past participle

Tekniskt möjligt men ovanligt i tal. Exempel:
- "The house may be being renovated at the moment." (grammatiskt korrekt men tungt — hellre: "The house may be under renovation.")

Särskilda fall: ought to, have to, need
- "Ought to": "The patient ought to be examined." ("Patienten bör undersökas.")
- "Have to" (semi-modalt): "The form has to be completed." ("Formuläret måste fyllas i.")
- "Need" som semi-modalt: "This need not be done." ("Detta behöver inte göras.") eller som lexical verb: "This does not need to be done."

Ordlista (kort)
