2. When do I use passive voice?
• The actor is unknown:
The paintings were made in the twentieth century. [We don't know who
made them.]
• The actor is irrelevant:
An experimental solar power plant will be built in the Australian desert. [We
are not interested in who is building it.]
• You want to be vague about who is responsible:
Mistakes were made. [Common in bureaucratic writing!]
3. • You are talking about a general truth:
Rules are made to be broken. [By whomever, whenever.]
• You want to emphasize the person or thing acted on. For example, it may be
your main topic:
Insulin was first discovered in 1921 by researchers at the University of
Toronto. It is still the only treatment available for diabetes.
• You are writing in a scientific genre that traditionally relies on passive voice.
Passive voice is often preferred in lab reports and scientific research
papers, most notably in the Materials and Methods section:
The sodium hydroxide was dissolved in water. This solution was then
titrated with hydrochloric acid.
4. How do we transform an active sentence into a passive
sentence?
1. The direct object of the active sentence becomes the subject (Pacient) of the
passive sentence.
2. We have to change the verb. We put the verb “to be” in the tense of the
active voice sentence, followed by the original verb in the past participle
form.
3. The active subject becomes the agent, always introduced by the preposition
“by”.
5. EXAMPLES:
Present Simple: take/s ---is/are taken
Past Simple: took---was taken
Present Perfect: have/has taken---has been taken
Past Perfect Simple: had taken---had been taken
Future with will: will take---will be taken
Going to future: going to be taken
Modal verb: must/can/should be
