The document discusses the passive voice and how to transform sentences from active to passive voice. The passive voice uses a form of the verb "to be" and the past participle of the main verb. When transforming a sentence from active to passive, the subject of the active sentence becomes the object of the passive sentence, and the object of the active sentence becomes the subject of the passive sentence. Several examples are provided demonstrating how to transform active sentences into their passive equivalents.

1. The passive voice.

2. Use of the passive.
• The passive voice is used when we say what
happens to people and things.

3. Form of the passive voice.
• When used the passive voice we need the verb to be and pas
participle of the main verb.
• The verb to be write them in the same tenses that the verb in
the active.
• Present simple: eat/s ----- am/is/are eaten
• Past simple: ate ----- was/were eaten
• Present perfect: Have/has eaten----- Have/has been eaten
• Past perfect: had eaten----- had been eaten
• Future with will: will eat---Will be eaten
• Going to: going to eat-----am/is/are going to be eaten
• Can: can eat----- can be eaten
• Must: must eat-----must be eat
• Should: Should eat----- Should be eaten

4. Active to passive transformation
• The rule general.
• In the active the object becomes the subject of the
passive and subject of the active becomes in the
object.
• We have two form the passive voice.
• 1possibility: In the active the indirect object becomes
the subject of the passive
• 2 possibility: In the active the direct object becomes
the subject of the passive.
• When we have in a sentence indirect and direct object
the form more usual is indirect object and the lass
usual is direct object.
