The document discusses the passive voice in English. It defines the passive voice as giving more importance to the action of the verb than the subject. The passive voice is used when the subject performing the action is unknown or unimportant. It provides examples of passive voice constructions in different tenses. It also explains how to transform sentences from active to passive voice by making the direct object the subject and using auxiliary verbs and the past participle form of the main verb.

to who or what has made this.
:

 We use the passive voice when we want to give more importance to
what happened that who performance the action.
: The order was given last week.

 Past perfect simple (had been + pp): A car had been stolen
 Future (will be + pp):The chair will be repaired while we are wait.
 Future (am/are/is going to be + pp):The chair is going to be repaired
next week.

4.  Transform sentences from active to passive
 The object of the active sentence becomes the subject of the passive
sentence
 The main verb is replaced by the auxiliary verb (to be) at the same time
and main verb in the past participle.
 The subject of the active sentence becomes the object of the passive
sentence.
 Who performed the action (if we went mention it) this will go preceded
by the preposition ‘by’.
