SpeakOut B1+ unit 5A

The passive voice shifts the focus from who performs the action to the object or result that receives it. To structure it, the original object moves to the front of the sentence, followed by the verb "to be" in the correct tense and the main verb in its past participle form. When completing the exercises, identify the original verb tense to maintain it in your transformation and decide if adding the agent at the end is necessary.

Fill in the blanks with the correct relative pronoun. If the pronoun can be omitted, write it in parentheses
