Choosing between Active and Passive Voice Verbs when Writing

Usually, effective writing uses the active voice and shuns the passive. Nevertheless, some situations are awkward or inappropriate when expressed in the active voice. Certainly, these situations call for the passive voice.   Choosing Active and PassiveVoice

  Exercises

Reasons to use the passive voice:

1. The agent (doer) of the action is unimportant. Example: The pyramids were built thousands of years ago.
2. The agent is unknown. Example: Several robberies were committed during the night.
3. The agent is common knowledge, and mentioning it would be redundant. Example: George Bush was elected in 2000.
5. The writer desires to control focus of sentence.  

to de-emphasize the agent’s role in the action Example: The alarm was triggered by my son. [Passive construction shifts focus away from the son’s responsibility.]
  to emphasize the party receiving the action Example: Jack was kicked by Jill.

 

Reasons to use the active voice:

The active voice is shorter and more direct. Compare:
Active: The waiter dropped the tray of food.
Passive: The tray of food was dropped by the waiter.
     
The active voice is less awkward and clearly states relationship between subject and action. Compare Passive: Your request for funding has been denied by the review committee.
Active: The review committee denied your request for funding.

The active voice sentence pattern propels the reader forward through your writing thus avoiding weak prose.


Identifying Passive Voice Verbs:

Verbs have two voices: active and passive.

In active voice sentences, the verb expresses the action in the sentence, the subject performs the action, and the object is the recipient of the action. Active sentences follow the pattern: subject-verb-object.

Jill kicked Jack.

In a passive voice sentence, the subject and object flip-flop. The subject becomes the passive recipient of the action.

Jack was kicked by Jill.


Form of Passive Voice Verbs:

The passive voice requires a "double verb" and will always consist of a form of the verb "to be" and the past participle (usually the "en/ed/t" form) of another verb. Example: is kicked

Writers should be familiar with the forms of "to be" so that they can easily identify the passive voice in their work.

Review the forms of "to be": am, is, are, was, were, be, being, been

Note the forms of "to be" in the examples of the verb "to kick" in various forms of the passive voice:

is kicked----------------had been kicked
was kicked-------------is going to be kicked
is being kicked---------will be kicked
has been kicked-------can be kicked
was being kicked------should be kicked

Often passive voice sentences will contain a "by" phrase indicting who or what performed the action. Passive sentences can be easily transformed into active sentences when the object of the preposition "by" is moved to the subject position in the sentence.

Passive: The cookies were eaten by the children.
Active: The children ate the cookies.

Passive: The tunnels are dug by the gophers.
Active: The gophers dug the tunnels.

Level 2 Revision Practice: Avoiding Passive Voice Verbs

Read this essay carefully paying special attention to passive voice verbs. Revise the essay by changing the passive verbs into active verbs where appropriate.

Mistakes
1. Technological civilization has reached its
2. present "advanced" state by the trial-and-error behavior of
3. those who lived before us. Many of the most useful
4. discoveries and inventions were the result of mistakes when
5. people were looking for something else. The New World was
6. found by Columbus, who was really looking for India. The
7. discovery of penicillin was speeded by somebody who left a
8. loaf of bread out to get moldy. Think how far behind
9. ourselves we’d be now if mistakes were impossible for us to
10. make.
11. Our knowledge is also increased by our mistakes, if
12. only because once a mistake has been made, a way of
13. correcting it must be found. If the mistake had not been
14. made by us in the first place, we might have had no reason
15. to learn how things are done. As I wrote the first version
16. of this essay, I made a few minor errors. As a result of my
17. mistakes, since I did discover them, I learned the
18. difference between continuous and continual; I learned that
19. useful has only one l (and that the rule goes for hundreds
20. of other words, like wasteful, harmful, spoonful); and I
21. learned how to use a semicolon when a comma won’t do.
22. Had I made no mistakes in the first place, I might
23. have had a pretty good essay, but I would still not have
24. known why.
25. Of course, mistakes have to be recognized for what they
26. are. If Columbus had thought San Salvador was India and let
27. things go at that, the world would be smaller today. Had
28. the moldy bread been tossed to the birds, the birds might
29. have become healthy while human life went on suffering from
30. raging diseases. (I realize these statements are somewhat
31. doubtful, but now I’m so curious about Columbus and
32. penicillin that I’m going to learn the real facts
33. tomorrow.)
34. Mistakes are made by computers, but only rarely by
35. comparison with the human brain’s continual bumbling. Human
36. beings, one might say, have emotions and desires and
37. prejudices that mistakes are the result of. Those quirks,
38. are not things that computers have. Distractions,
39. and fatigue are suffered by human beings but not by
40. computers. So it is possible to say that we are in a bit of
41. danger. If the time should ever come when most of the
42. world’s work is done by computers rather than by people,
43. fewer mistakes will be made. And fewer mistakes will mean
44. fewer of those useful discoveries and inventions brought
45. about by the stumblings of the human species.
