The Passive Form

The Passive Form
The passive of an active tense is formed by putting the verb to be into the same tense as the active verb and adding the past participle of the active verb.

When should we use the Passive form of the verb?

First: when the subject is unimportant:
1. Parents put the children to bed at seven o’clock.
.............................................................................

1. The cook has spoilt the meat.
............................................................................
2. My brother broke your television.

Third: in order to replace a “thing” subject by a “person” subject:

3. A bus ran over an old man.
