be verbs

You should generally prefer active verbs to forms of be. However, not every be verb needs replacing. The forms of be work well when you want to link a subject to a complement, a noun that renames it or an adjective that describes it.

And when used as helping verbs before present participles (is flying, are disappearing) to express ongoing action, be verbs are fine.

If using a be verb makes a sentence needlessly dull or wordy, however, consider replacing it. Often a phrase following the verb will contain a word (such as violation) that suggests a more vigorous, active alternative (violate).

Violate is less wordy and more vigorous than be in violation of.

Resisted is stronger than was resistant to.
