Объяснение:
Сказуемое в пассивном залоге всегда состоит из формы глагола to be и третьей формы глагола (которая называется причастием прошедшего времени, past participle).
По временам изменяется только to be, причастие никогда не меняется.
После модальных глаголов нужно использовать пассивный инфинитив - to be + 3я форма глагола (см. пример в пункте 20).
