Clarity and meaning

The primary reason why your instructors frown on the passive voice is that they often have to guess what you mean. Sometimes, the confusion is minor. Let's look again at that sentence from a student's paper on Homer's The Odyssey:

When her house was invaded, Penelope had to think of ways to delay her remarriage.
Like many passive constructions, this sentence lacks explicit reference to the actor—it doesn't tell the reader who or what invaded Penelope's house. The active voice clarifies things:
After suitors invaded Penelope's house, she had to think of ways to fend them off.

Thus many instructors—the readers making sense of your writing—prefer that you use the active voice. They want you to specify who or what is doing the action. Compare the following two examples from an anthropology paper on a Laotian village to see if you agree.
(passive) A new system of drug control laws was set up. (By whom?)
(active) The Lao People's Revolutionary Party set up a new system of drug control laws.
Here's another example, from the same paper, that illustrates the lack of precision that can accompany the passive voice:
Gender training was conducted in six villages, thus affecting social relationships.
And a few pages later:
Plus, marketing links were being established.
In both paragraphs, the writer never specifies the actors for those two actions (Who did the gender training? Who established marketing links?). Thus the reader has trouble appreciating the dynamics of these social interactions, which depend upon the actors conducting and establishing these things.
The following example, once again from that paper on The Odyssey, typifies another instance where an instructor might desire more precision and clarity:
Although Penelope shares heroic characteristics with her husband, Odysseus, she
is not considered a hero.

Who does not consider Penelope a hero? It's difficult to tell, but the rest of that paragraph suggests that the student does not consider Penelope a hero (the topic of the paper). The reader might also conceivably think that the student is referring to critics, scholars, or modern readers of The Odyssey. One might argue that the meaning comes through here—the problem is merely stylistic. Yet style affects how your reader understands your argument and content. Awkward or unclear style prevents your reader from appreciating the ideas that are so clear to you when you write. Thus knowing how your reader might react enables you to make more effective choices when you revise. So after you identify instances of the passive, you should consider whether your use of the passive inhibits clear understanding of what you mean.
Verbs are also said to be either active (The executive committee approved the new policy) or passive (The new policy was approved by the executive committee) in voice. In the active voice, the subject and verb relationship is straightforward: the subject is a be-er or a do-er and the verb moves the sentence along. 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). Computerized grammar checkers can pick out a passive voice construction from miles away and ask you to revise it to a more active construction. There is nothing inherently wrong with the passive voice, but if you can say the same thing in the active mode, do so (see exceptions below). Your text will have more pizzazz as a result, since passive verb constructions tend to lie about in their pajamas and avoid actual work.
We find an overabundance of the passive voice in sentences created by self-protective business interests, magniloquent educators, and bombastic military writers (who must get weary of this accusation), who deviluse the passive voice to avoid responsibility for actions taken. Thus "Cigarette ads were designed to appeal especially to children" places the burden on the ads — as opposed to "We designed the cigarette ads to appeal especially to children," in which "we" accepts responsibility. At a White House press briefing we might hear that "The President was advised that certain members of Congress were being audited" rather than "The Head of the Internal Revenue service advised the President that her agency was auditing certain members of Congress" because the passive construction avoids responsibility for advising and for auditing. One further caution about the passive voice: we should not mix active and passive constructions in the same sentence: "The executive committee approved the new policy, and the calendar for next year's meetings was revised" should be recast as "The executive committee approved the new policy and revised the calendar for next year's meeting."
Take the quiz (below) as an exercise in recognizing and changing passive verbs.

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.
The passive voice is especially helpful (and even regarded as mandatory) in scientific or technical writing or lab reports, where the actor is not really important but the process or principle being described is of ultimate importance. Instead of writing "I poured 20 cc of acid into the beaker," we would write "Twenty cc of acid is/was poured into the beaker." The passive voice is also useful when describing, say, a mechanical process in which the details of process are much more important than anyone's taking responsibility for the action: "The first coat of primer paint is applied immediately after the acid rinse."
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.
The executive committee approved an entirely new policy for dealing with academic suspension and withdrawal. The policy had been written by a subcommittee on student behavior. If students withdraw from course work before suspension can take effect, the policy states, a mark of "IW" . . . .
The paragraph is clearly about this new policy so it is appropriate that policy move from being the object in the first sentence to being the subject of the second sentence. The passive voice allows for this transition.†
