Passive Voice or Active Voice in EnglishB1

Active voice and passive voice can describe the same event from different angles. In The chef cooked the meal, the focus is on the chef. In The meal was cooked, the focus moves to the meal. The event is the same, but the sentence highlights a different part of it. That is why these two forms often appear side by side when learners compare them.

In active voice, the subject does the action. In The child broke the vase, the child is the subject and the doer. In passive voice, the subject receives the action. In The vase was broken, the vase is the subject, and the action happens to it. Active voice follows subject + verb + object. Passive voice follows subject + be + past participle, and the object of the active sentence becomes the subject of the passive sentence.
