In most instances, put the verb in the active voice rather than in the passive voice. Passive voice produces a sentence in which the subject receives an action. In contrast, active voice produces a sentence in which the subject performs an action. Passive voice often produces unclear, wordy sentences, whereas active voice produces generally clearer, more concise sentences. To change a sentence from passive to active voice, determine who or what performs the action, and use that person or thing as the subject of the sentence.
Examples
Passive voice:
On April 19, 1775, arms were seized at Concord, precipitating the American Revolution. Active voice:
On April 19, 1775, British soldiers seized arms at Concord, precipitating the American Revolution.
Other examples of passive voice:
1. The process of modernization in any society is seen as a positive change.
2. The Count is presented as an honest, likeable character.
3. Thomas Jefferson's support of the new Constitution was documented in a letter to James Madison.
Overuse of "to be"(a related problem)
Use of forms of to be (is, are, was, were) leads to wordiness. Use an action verb in place of a form of to be.
Example:
It is the combination of these two elements that makes the argument weak. revision:
The combination of these two elements weakens the argument.
