35 Active and Passive Voice

There are two main “voices” in English writing: the active voice and the passive voice. You’ve probably heard a lot about them—and you’ve probably been warned away from the passive voice. But what exactly are they?

In the simplest terms, an active voice sentence is written in the form of “A does B.” (For example, “Carmen sings the song.”) A passive voice sentence is written in the form of “B is done by A.” (For example, “The song is sung by Carmen.”) Both constructions are grammatically sound and correct. Let’s look at a couple more examples of the passive voice:

  • I’ve been hit! (or, I have been hit!)
  • Jasper was thrown from the car when it was struck from behind.

You may have noticed something unique about the previous two sentences: the subject of the sentence is not the person (or thing) performing the action. The passive voice “hides” who does the action. Despite these sentences being completely grammatically sound, we don’t know who hit “me” or what struck the car.

The passive is created using the verb to be and the past participle. When identifying passive sentences, remember that to be has other uses than just creating the passive voice. “She was falling” and “His keys were lost” are not passive sentences. In the first, to be is a continuous past verb, and in the second to be is past tense linking verb. There are two key features that will help you identify a passive sentence:

  1. Something is happening (the sentence has a verb that is not a linking verb).
  2. The subject of the sentence is not doing that thing.

Usage

As you read at the two sentences below, think about the how the different voice may affect the meaning or implications of the sentence:

  • Passive voice: The rate of evaporation is controlled by the size of an opening.
  • Active voice: The size of an opening controls the rate of evaporation.

The passive choice slightly emphasizes “the rate of evaporation,” while the active choice emphasizes “the size of an opening.” Simple. So why all the fuss? Because passive constructions can produce grammatically tangled sentences such as this:

Groundwater flow is influenced by zones of fracture concentration, as can be recognized by the two model simulations (see Figures 1 and 2), by which one can see . . .

The sentence is becoming a burden for the reader, and probably for the writer too. As often happens, the passive voice here has smothered potential verbs and kicked off a runaway train of prepositions. But the reader’s task gets much easier in the revised version below:

Two model simulations (Figures 1 and 2) illustrate how zones of fracture concentration influence groundwater flow. These simulations show . . .

To revise the above, all we did was look for the two buried things (simulations and zones) in the original version that could actually do something, and we made the sentence clearly about these two nouns by placing them in front of active verbs. This is the general principle to follow as you compose in the active voice: Place concrete nouns that can perform work in front of active verbs.

Practice

Are the following sentences in the active or passive voice? How can you tell?

  1. The samples were prepared in a clean room before being sent out for further examination.
  2. Karen was dancing with Joshua when she suddenly realized she needed to leave.
  3. Carlos was a very serious scientist with unique interests.

  1. This sentence uses the passive voice. The action (prepared) was done to the subject of the sentence (samples). If this sentence were written in the active it would be something like this: “[Actor] prepared the samples in a clean room before sending them out for further examination.” Since we do not know who prepared the samples, the active sentence is incomplete.
  2. This sentence uses the active voice. In this case was indicates that the sentence happened in the past; it does not indicate the passive voice.
  3. This sentence uses the active voice. In this case was is acting as a linking verb. It links Carlos with the phrase very serious scientist.

Revise Weak Passive-Voice Sentences

As we’ve mentioned, the passive voice can be a shifty operator—it can cover up its source, that is, who’s doing the acting, as this example shows:

  • Passive: The papers will be graded according to the criteria stated in the syllabus.
    • Graded by whom though?
  • Active: The teacher will grade the papers according to the criteria stated in the syllabus.

It’s this ability to cover the actor or agent of the sentence that makes the passive voice a favorite of people in authority—policemen, city officials, and, yes, teachers. At any rate, you can see how the passive voice can cause wordiness, indirectness, and comprehension problems.

For many years, federal regulations concerning the use of wire-tapping have been ignored. Only recently have tighter restrictions been imposed on the circumstances that warrant it. Who has ignored the regulations, and who is now imposing them? For many years, government officials have ignored federal regulations concerning the use of wire-tapping. Only recently has the federal government imposed tighter restrictions on the circumstances that warrant it.

Practice

Convert these passive voice sentences into the active voice. Why is the active voice a better choice for each of these sentences?

  1. The process, which was essential for the experiment’s success, was completed by Enzo.
  2. The cake that I worked on all day long is being eaten by Justin.
  3. After the pattern has been applied to the fabric, work on the embroidery can be started.

  1. Enzo completed the process, which was essential for the experiment’s success.
    • In the passive sentence, the which-clause makes the subject of the sentence excessively long. By converting the sentence to the active voice, the clause is moved to the predicate, which makes the sentence easier to understand.
  2. Justin is eating the cake that I worked on all day long.
    • The active voice works better in this sentence for the same reasons as sentence one. It is also likely that you would want to put emphasis on Justin in this sentence. After all, he’s doing something that is (most likely) inconsiderate.
  3. After you apply the pattern to the fabric, you can start working on the embroidery.
    • This sentence is likely found in a set of instructions, which are usually written directly to the reader. Addressing “you” and avoiding the passive voice will make the instructions feel more natural and accessible.

Don’t get the idea that the passive voice is always wrong and should never be used. It is a good writing technique when we don’t want to be bothered with an obvious or too-often-repeated subject and when we need to rearrange words in a sentence for emphasis. The next page will focus more on how and why to use the passive voice.
