The document discusses the passive voice in English. It explains that the passive voice is used when the focus is on the action rather than the subject performing the action. It provides examples of transforming sentences from the active to the passive voice by changing the subject and verb. The key points are that the object of the active sentence becomes the subject in the passive, a form of "to be" plus the past participle is used, and the original subject may become an object or be omitted in the passive form. Five examples are given of changing active sentences to passive.

5. 4.ACTIVE TO PASSIVE TRANSFORMATION.
CHANGES IN THE SENTENCE
 To to form a passive sentence from
an active one we have to take into
account the following points.
 The object of the active sentence
becomes the subject in the passive
sentence.
 We have to use a form of the verb “to
be” + the past participle of the verb
that we have in the active sentence.
 The subject of the “active” sentence
becomes the object of the passive (or
is left out).
