to be + past participle

How to form a passive sentence when an active sentence is given:

• object of the active sentence becomes subject in the passive sentence
• subject of the active sentence becomes object in the passive sentence (or is left out)

We can only form a passive sentence from an active sentence when there is an object in the active sentence.
