Unit 16: The Passive & Impersonal Structures
1. The Passive Voice
The passive voice is formed using the verb to be + past participle of the main verb. The passive exists in every tense. We use the passive voice when:
- We want to say what happens to the subject rather than what the subject does.
- The person who causes the action is unknown or unimportant.
- We want to emphasize the action or the receiver of the action.
If we want to mention who performed the action, we use by + agent (e.g., “The book was written by Jane Austen”). However, if the agent is obvious or non-specific (like ‘someone’ or ‘people’), it is often omitted.
2. The Impersonal Structure
An impersonal structure is used to talk about people in general or to make statements less personal. Common structures include:
- Passive without the agent: “We are expected at 7pm.” (Somebody expects us).
- ‘It’ + ‘to be’ + adjective + infinitive: “It is sometimes exciting to walk in the rain”.
- Gerund as subject: “Reading English newspapers is often difficult”.
- Reporting Verbs: Structures like “It is said that…” or “It is believed that…” are often used in formal writing.
