Converting present perfect interrogative active to passive requires careful subject-object switching. Original: “Has he phoned her?” Passive: “Has she been phoned by him?” Structure: auxiliary (has) + new subject (she) + been + past participle (phoned) + agent (by him). The question format maintains auxiliary-front position. This transformation shifts focus to the recipient of the phone call while preserving the interrogative form.
