About This Resource
This B1–B2 resource develops the passive voice as a way to choose which participant becomes the grammatical subject. It covers common tense and modal passive forms, by-phrases, verbs that can form passives, and the information-focus reasons for choosing passive rather than active structure.
What You’ll Learn
• Form basic passives with be + past participle.
• Build passive forms in common simple, progressive, perfect, and modal patterns.
• Decide when the agent can be omitted or expressed in a by-phrase.
• Choose active or passive structure according to focus and information flow.
