Soru: "They built this house in 1990." cümlesinin pasif hali aşağıdakilerden hangisidir?
Çözüm:
- Active cümle: Subject (They) + Verb (built) + Object (this house) + Time (in 1990).
- Passive yapmak için: Object (this house) → Subject; Verb → "be" + V3 (past participle); Original subject (They) → by-agent (by them) veya atlanabilir.
- Verb "built" past tense, V3 formu "built".
- Passive cümle: "This house was built in 1990 (by them)."
- Doğru seçenek: "This house was built in 1990."
