More about Passive Voice
This handout will explain the difference between active and passive voice in writing. It gives examples of both, and shows how to turn a passive sentence into an active one. Also, it explains how to decide when to choose passive voice instead of active.

In a sentence using passive voice, the subject is acted upon; he or she receives the action expressed by the verb. The agent performing the action may appear in a "by the..." phrase or may be omitted.
Reasons to Generally Avoid Passive Voice
Sometimes the use of passive voice can create awkward sentences, as in the last example above. Also, overuse of passive voice throughout an essay can cause your prose to seem flat and uninteresting. In scientific writing, however, passive voice is more readily accepted since using it allows one to write without using personal pronouns or the names of particular researchers as the subjects of sentences (see the third example above). This practice helps to create the appearance of an objective, fact-based discourse because writers can present research and conclusions without attributing them to particular agents. Instead, the writing appears to convey information that is not limited or biased by individual perspectives or personal interests.
Recognizing Passive Voice
You can recognize passive-voice expressions because the verb phrase will always include a form of be, such as am, is, was, were, are, or been. The presence of a be-verb, however, does not necessarily mean that the sentence is in passive voice. Another way to recognize passive-voice sentences is that they may include a "by the..." phrase after the verb; the agent performing the action, if named, is the object of the preposition in this phrase.
You can recognize passive voice 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 prepositional phrase like "by the" in the sentences above indicates that the action is performed on the subject, and that the sentence is passive.
