The passive voice shifts the focus from who does the action to what receives the action. It is formed with "be + past participle" and is essential in academic, scientific, and journalistic writing.

Forming the Passive
The passive is formed with the correct tense of "be" + the past participle of the main verb. The subject of the active sentence becomes the object in the passive, and vice versa. "Someone built this house in 1920." → "This house was built in 1920." The agent (doer) can be included with "by": "…was built by a local architect."
Passive Across Tenses
The passive exists in all major tenses. Present simple passive: "is/are + past participle". Past simple: "was/were + pp". Present perfect: "has/have been + pp". Past perfect: "had been + pp". Future: "will be + pp". Modal passives: "can/should/must + be + pp". The pattern is always some form of "be" + past participle.
When to Use the Passive
Use the passive when: the doer is unknown ("My bike was stolen"), the doer is obvious or unimportant ("The suspect was arrested"), you want to focus on the action rather than who did it (scientific writing: "The solution was heated to 80°C"), or to avoid assigning blame ("Mistakes were made"). Overusing the passive in everyday conversation sounds unnatural.
