Объяснение:
Пассивный залог образуется по схеме: to be + past participle (причастие прошедшего времени, оно же 3я форма глагола).
По временам изменяется только глагол to be.
При преобразовании активного залога в пассивный важно сохранить время сказуемого (past simple остаётся past simple, меняем только залог!)
