This document provides an overview of active and passive sentences. It defines active sentences as those where the subject performs the action and passive sentences as those where the object of an action becomes the subject. The key differences are that active sentences emphasize who performs the action while passive sentences emphasize the object of the action or are used when the performer is unknown. The document demonstrates how to identify active and passive sentences and how to convert between the two voices by changing the verb and moving the original subject to become the object introduced by "by". Exercises are provided for practice distinguishing and converting between active and passive sentences.

3. 1. What’s a active sentence?
The first thing that we have to know is to identify a active sentence:
The active voice is the way that we use to speak habitually.
Someone (a person “the subject”) realizes (or it doesn’t realize) an action.
Then, can you identify the active sentences?
- Matt is cutting an orange.
SOMEONE (MATT) REALIZES AN ACTION (CUT AN ORANGE)
- She’s writing a letter.
SOMEONE (SHE) REALIZES AN ACTION (WRITE A LETTER)
- Everybody think that George Clooney is a great actor.
SOMEONE (EVERYBODY) REALIZES AN ACTION (THINK SOMETHING)
VERY WELL!
All the sentences
are active!

4. 2. What’s a passive sentence?
Now, we are going to identify a passive sentence:
In the passive voice, the object resultant or obtained of the action is the subject
of the sentence. With this, we highlight the importance of the object. We
change the verb (We’ll see it after) and we put who realizes the action with
“by”.
For example: The orange is cutted by Matt.
(THE ORANGE (THE OBJECT, AND NOW THE SUBJECT TOO) IS
CUTTED (WE CHANGE THE VERB) BY MATT (WHO REALIZES
THE ACTION) )
Ok. Do this exercise: Which sentence is passive?
1. Sara did her homerworks.
2. The homeworks was done by Sara.
Perfect!
The correct answer
is B.

5. 3.Which is the difference
between both?
The principal difference between active and
passive voice is the subject:
[ACTIVE]
We use the active habitually,
without thinking. We know who
realize the action and we only
want to informate.
[PASSIVE]
We only use the passive when
we are interested in the object
or when we don’t know who
realize the action.

Index.
Actually, you know what’s a active
sentence or a passive sentece. You know
which is the difference between both
and how to turn a active
sentence in a passive.
