2. When we want to give more
importance to the action
instead of the person who
performs it we use the
passive voice.
3. To transform an active sentence
to passive we consider the
following points:
-The subject of a verb in passive voice
corresponds to the direct object of a verb in
active voice.
-The passive voice is formed using the verb “to
be” + the main verb participle (past
participle).
-The subject of the main sentence becomes the
complement agent of the passive.
-To say who person does the action we use “by”.
4. Examples of how to
transform the verb tenses
