THE PASSIVE VOICE

We already know that sentence structure in English, as well as many other languages, is formed in the following order:

Subject + Verb + Object - Right? 

Well, this structure we refer to as the active voice. Sometimes we need to use a different structure in which the object is emphasized and it takes the place of the subject.  This is referred to as the passive voice. 

In this lesson we will examine the difference between active and passive.  We also will look at when, why, and how the passive is formed. 

What is the passive voice?

The passive voice may pose some difficulties not in forming it, but in using it.  Many may find it difficult to decide when the passive voice may be used. One of the reasons why this difficulty exists is that there aren't many languages that use passive voice, and in those languages that do, the passive is formed somewhat differently. 

By now we certainly know that English uses subject-verb-object format. In this structure, the subject is the main focus and the object is the secondary focus of the sentence.  For example, if "Maria drew a picture". Maria is the main focus of the sentence and a picture is the secondary focus. 

To explain this further, it is a good idea to think of action sentences like the above in terms of a doer and a receiver.

In the sentence above, the doer is Maria because she did the action; and the receiver is the picture because it received the action. If we need to emphasize the object of the sentence, we use it first.  The sentence then will be: "A picture was drawn by Maria." In this sentence, the doer of the action (Maria) becomes unimportant and secondary.  The focus is on the receiver (a picture). 

In addition to focusing on the object or the receiver of the action, there is another reason why the passive voice is used. Sometimes we may need to hide the doer, not mention who did the action at all.  This is often done in advertising. Advertisers often tell us that a particular product was proven to be the best or number one, but they never tell us who proved it.

We will see this in more detail later. 

How is the passive voice formed?

First let us compare the following sets of sentences: 

Active:

Maria ate the sandwich.
Hillary wrote a book
The Queen of England visited Egypt.
Doctors found a cure for the flu.

 Passive:

The sandwich was eaten by Maria.
A book was written by Hillary.
Egypt was visited by the Queen of England
A cure for the flu was found by doctors.

Now that you looked at these sentences, what do the passive sentences have in common? Read them again slowly before you answer the question. 

Did you find the similarities? Well, here they are, all the passive sentences have verb to be and a main verb in the past participles.

BE + Past Participle of a verb 

So, it is safe to say that using verb to be and a verb in the past participle creates the passive voice. 

WAS + BROKEN
HAS BEEN + WRITTEN
HAVE BEEN + SEEN
HAD BEEN + PAINTED

The steps we take to form the passive:

(1) Emphasize the object of the sentence by making it the subject.
To change the active sentence "Maria ate the sandwich" to passive, we need to start the sentence with "The sandwich..." 
 
(2) Make the subject of the active sentence an object in the passive.
"The sandwich ...........Maria." 
 
(3) Add the preposition 'by' before the new object.
"The sandwich ........by Maria." 
 
(4) Decide what tense the main verb is in, and use verb to be in the same tense.
In the sentence "Maria ate the sandwich," the verb ate is in the past tense.  Therefore, I use verb to be in the past tense.
"The sandwich was ..... by Maria."
 
(5) Finally, change the main verb to the past participle.
Here the main verb is 'eat' and the past participle is 'eaten'.
So the new passive sentence will be:
The sandwich was eaten by Maria.

Just for more practice, let us assume various tenses.

(1) Active: Maria has eaten the sandwich.
     Passive: The sandwich has been eaten by Maria. 
 
(2) Active: Maria had eaten the sandwich.
    Passive:  The sandwich had been eaten by Maria.
 
(3) Active: Maria will be eating the sandwich.
    Passive: The sandwich will be eaten by Maria. 
 
(4) Active: Maria is eating the sandwich.
    Passive: The sandwich is being eaten by Maria 

This last sentence can be confusing.  Let us analyze it.

In the active, the verb 'eat' is in the present continuous; so, we need verb to be in the present continuous.  Surely you remember that the continuous is formed by using verb to be + the verb ending in -ing.  This means that verb 'to be' in the present continuous is (is being). Then we use the past participle of the main verb, so the phrase will be 'is being' eaten.   

If you are still confused, don't worry.  The exercises that will follow will clarify this for you.  

Let us practice:

Change the following active sentences into passive.  Follow the steps outlined above.

1-   Juan broke the window.
2-   Leonardo da Vinci painted the Mona Lisa.
3-   The mechanic fixed the car.
4-   Maria cooked dinner.
5-   The student wrote the essay.

How did you do? Very well, I am sure. 

Now compare your responses to mine.

Passive:

1-   The window was broken by Juan.
2-   The Mona Lisa was painted by da Vinci.
3-   The car was fixed by the mechanic.
4-   Dinner was cooked by Maria.
5-   The essay was written by the student.     

 Please note:

The passive form is not desirable in English writing. It is always better and more effective to write active sentences.

However, sometimes using the passive is necessary.  This happens in sentences that do not have an explicit or known doer. In fact, more than 85 percent of the commonly used passive is used when the sentence does not have an explicit doer.

 For example:

Grapes are grown in the valley.

Notice that there is no doer in this sentence. Of course the doer is implied as the farmers or the people of the valley, but is not stated. 

Here are some other examples of sentences in the passive because they do not have an explicit doer:

-The freeway construction will be completed in July.
-Maria's car was stolen.
-The papers have been destroyed.
-John was hurt in the accident.
-The star can be seen from the balcony.
-Mr. John should be elected mayor.
-More hospitals should be built.

Notice that all the sentences above have no doer. So, again, we use the passive when there is no explicit doer.
