What is the difference between active and passive voice?
In a sentence using active voice, the subject of the sentence performs the action expressed in the verb.
Examples:The dog jumped onto the boy.
Kristy will give a book report to the class.
The computer ate my paper.
In a sentence using passive voice, the subject is acted upon; he or she receives the actionexpressed by the verb.
The boy was jumped on by the dog.
A book report will be given by Kristy to the class.
My paper was eaten by the computer.
Helpful Hint: You can recognize passivevoice because the verb phrase will include a form of be (was, am, are, been, is). Don't assume that just because there is a form of 'be' that the sentence is passive, however. Sometimes a prepositionalphrase like "by the" in the sentences above indicates that the action is performed on the subject, and that the sentence is passive.
When to choose active voice?
