Passives for Pre-Intermediate

Passive sentences are used to focus on the object, or when the agent is unknown. The object of the active verb is the subject of the passive verb. Compare:

Active: The boy broke the cup.
Passive: The cup was broken (by the boy).

In passives, the subject does not perform the action in the sentence - the action is performed on it.

The passive is formed by using the auxiliary verb be + past participle.

We use passives more in written English more than spoken English. In passive sentences the agent (the person/thing) that did an action does not have to be mentioned. We use the passive when leaving out the agent, i.e. when the agent is clear, not known or not important.
