4th PASSIVE VOICE-EASSY GRAMMAR

The passive is formed with the Present or Past Simple of the verb to be + the past participle of the main verb.

Examples:
Meals are prepared daily.
The theater was destroyed by a bomb.

We use the Passive when we want to give more importance to the action and its object than to the agent of the action.

Example:
The letters were delivered late.

The subject of the Active verb (the agent) is preceded by the preposition by in the Passive.

Example:
The Normans conquered Britain in 1066. (Active)
Britain was conquered by the Normans in 1066. (Passive)

By + agent is only omitted when it is not important or unknown.

Examples:
Someone stole my handbag. (Active)
My bag was stolen (Passive)
