Analize the picture and the sentences

Active: Beautiful giraffes roam the savannah.
Passive: The savannah is roamed by beautiful giraffes.
Roam: wander around a place(deambular, vagar)

What country is the Savannah located in? The savannah is a grassland biome found worldwide in the areas near the equator. Savanna grasslands cover half of the African continent, including the Serengeti Plains of Tanzania, perhaps the world's most famous savanna. Savannas also cover portions of northern Australia, India, Brazil, Colombia and Venezuela.




To change a sentence from active to passive voice, do the following:

         ACTIVE VOICE                                           PASSIVE VOICE 
Sara mailed the letter yesterday            The letter was mailed by Sara yesterday

              verb                                                         verb be auxiliary + past participle


 
ACTIVE
PASSIVE
In most English sentences with an action verb, the subject performs the action denoted by the verb.

Use the active form of a verb to focus on the “doer” or cause of the action.

   
One can change the normal word order of many active sentences (those with a direct object) so that the subject is no longer active, but is, instead, being acted upon by the verb - or passive.  

Use the passive form to focus on the “receiver” of the action.
These example shows that the subject is  doing the verb's action.

v The man must have eaten five hamburgers

     The man (subject) is doing the eating (verb).
Note in these examples how the subject-verb relationship has changed.

v Five hamburgers must have been eaten by the man.

    Five Hamburgers (subject) are being eaten (verb)
Example:
Example:
1.  A student found a bag on a bus.
2.  The authorities close the airport.
3.  A teenager has seen two bears in a yard.
4.  The accident didn’t injure the passengers.
1.   A bag was found on a bus.
2.   The airport is closed by the authorities.
3.   Two bears have been seen in a yard.
4.   The passengers weren’t injured.
Because the subject does or "acts upon" the verb in such sentences, the sentences are said to be in the active voice.
Because the subject is being "acted upon" (or is passive), such sentences are said to be in the passive voice.

ACTIVE VOICEAt each concert, the soprano sang at least one tune from a well-known opera.
                                                    doer of action action Receiver of action 
PASIVE VOICEAt each concert, at least one tune from a well-known opera WAS SUNG by the soprano.
                                                                     receiver of action                               action            doer of action 




Use of Passive
Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: Books are made of paper.
In the example above, the focus is on the fact that books are made of paper. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: Shoes are made of leather.
In this case, I focus on the fact that shoes are made of leather, but I do not blame anyone (e.g. You make shoes.)

Form of Passive

Subject + finite form of to be + Past Participle 
Example: Erasers are made of rubber.

Passive Sentences with Two Objects Level 3

Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on.
SubjectVerbObject 1Object 2
Active:Ritawrotea letterto me.
Passive:A letterwas writtento meby Rita.
Passive:Iwas writtena letterby Rita.
.
As you can see in the examples, adding by Rita does not sound very elegant. Thats why it is usually dropped.

Personal and Impersonal Passive

Personal Passive simply means that the object of the active sentence becomes the subject of the passive sentence. So every verb that needs an object (transitive verb) can form a personal passive.
Example: They build houses. – Houses are built.
Verbs without an object (intransitive verb) normally cannot form a personal passive sentence (as there is no object that can become the subject of the passive sentence). If you want to use an intransitive verb in passive voice, you need an impersonal construction – therefore this passive is called Impersonal Passive.
Example: he says – it is said
Impersonal Passive is not as common in English as in some other languages (e.g. German, Latin). In English, Impersonal Passive is only possible with verbs of perception (e. g. say, think, know).
Example: They say that women live longer than men. – It is said that women live longer than men.
Although Impersonal Passive is possible here, Personal Passive is more common.
Example: They say that women live longer than men. – Women are said to live longer than men.
The subject of the subordinate clause (women) goes to the beginning of the sentence; the verb of perception is put into passive voice. The rest of the sentence is added using an infinitive construction with 'to' (certain auxiliary verbs and that are dropped).
Sometimes the term Personal Passive is used in English lessons if the indirect object of an active sentence is to become the subject of the passive sentence.
