The passive voice
In the passive voice, the subject of the sentence is neither a do-er or a be-er, but is acted upon by some other agent or by something unnamed (The new policy was approved).
The passive voice does exist for a reason, however, and its presence
is not always to be despised. The passive is particularly useful (even
recommended) in two situations:
- When it is more important to draw our attention to the person or thing acted upon: The unidentified victim was apparently struck during the early morning hours.
- When the actor in the situation is not important: The aurora borealis can be observed in the early morning hours.
We use the passive voice to good effect in a paragraph in which we wish to shift emphasis from what was the object in a first sentence to what becomes the subject in subsequent sentences.
