Peter arrives at the University with the intention of attending the inaugural lecture. The inaugural lecture was given two hours earlier. Peter did not know who had given the lecture or what it had been about.
Having been informed by email almost everybody at the university attended, with the exception of Peter of course.
Emails were designed to communicate information but not of an urgent nature. Peter is rather old school in that respect and only consults his emails at night.
He thought that SMS was developed for transmitting urgent information, a sort of latter-day telegram. Peter was surprised by the number of students starting at the university the same day.
All students are required to consult their emails three times a day.
Communication by email is expected to be the norm in academic circles before long.
He should have known better.
There are reported to have been 250 billion emails sent each and every day in 2009.
It is thought that this figure has doubled since.
Peter was given this information by Sara and she is known for her accuracy in such matters.
You could say that the information was given to Peter by Sara for a reason but Peter had not realised the relevance.
So as he has a couple of hours to kill, he decides to attend an open lecture that is just about to start in the main hall.
It is all about European economies and as Peter is going to study Spanish, he finds that some aspects of the lecture are quite interesting.
Tourism is considered to be Spain’s largest industry.
Without tourism, it is estimated that the GDP of Spain would fall noticeably.
The lecture continues but Peter starts to daydream and think about his present situation.
Peter is ready to dive into his studies, as it has been a long-standing ambition of his to go on to further education.
He wanted to kick off with the inaugural lecture, but it was not to be. He was now ready and unless something crops up,
there shouldn’t be more hiccups. Instead of whiling away his time, he could now knuckle down to some serious study.
He was going to make up for lost time and press on with the task at hand. It does not know what is lying ahead but he had
ended up at university because he had wanted to.
He had decided to work really hard during the week until Friday when he can knock off studying early and wind down over the
He had learned how to pace himself and avoid getting snowed under with work.
All these skills would be potentially useful to him.
The active voice is often referred to as the normal voice.
However the passive voice is necessary as we might not know or have the active subject.
Active voice (simple sentence with one clause)
= Subject + Verb + Object
Here the object receives the action of the verb.
Sandra has bought the tickets.
All the elements of the sentence are important in the active voice.
Passive voice = Subject + Verb + by + Passive Agent
Sometimes in the passive voice we remove the passive agent as it is not considered important.
The subject of the active voice (active subject)
becomes the passive agent in the passive voice and is introduced by the preposition “by”.
The tickets have been bought (by Sandra).
The tense changes in the passive voice too.
Use of the passive voice:
Firstly, all the importance is given to the active agent:
The object of my active voice becomes the subject in the passive voice.
Secondly, the active subject is unknown.
I had my wallet stolen.
Here, I don’t know who stole my wallet,
so I have no passive agent in my sentence.
Thirdly, we use the passive for structure variety and flow.
if I take the object from my previous sentence.
To do the tense transformations from active voice to passive voice please review the following points:
Past participle, irregular verbs and tense review.
Transformations when going from the active voice to the passive voice:
What tense to use?
Example: Her visa + “to be” + past participle of the main verb
“To extend” becomes “extended”
We take the tense used in the active voice to conjugate the verb “to be” in the passive voice
and add the past participle of the main verb of the active voice.
To extend – extended
Firstly, Simple Present:
They extend her visa. – Active voice
Her visa is extended. – Passive voice
Secondly, Present Continuous:
They are extending her visa.
Her visa is being extended.
Thirdly, Simple Past:
They extended her visa.
Her visa was extended.
Fourthly, Present Perfect:
They have extended her visa.
Her visa has been extended.
Fifthly, Past Perfect:
They had extended her visa.
Her visa had been extended.
Sixthly, Simple Future:
They will extend her visa.
Her visa will be extended.
Seventhly, Future Perfect:
They will have extended her visa.
Her visa will have been extended.
Eightly, Simple Conditional:
They would extend her visa.
Her visa would be extended.
Ninethly, Conditional Perfect:
They would have extended her visa.
Her visa would have been extended.
More about passive and active voices:
We can also distinguish personal from impersonal passive.
Firstly, personal passive = the object of the active sentences becomes the subject of the passive sentence.
So all transitive verbs can form a personal passive.
A transitive verb means that it can be followed by an object.
Example : She built a new house. A new house was built.
Secondly, impersonal passive means that the verb cannot have an object.
They are intransitive verbs.
They cannot form a personal passive sentence.
(Meaning there is no object in the active voice that can be used as the subject of the passive form.)
In this case and in order to use the same verb in both the active and passive voice you will need the preposition “It”.
Example : They said, becomes… It is said.
