What are active and passive voice?

The active voice emphasizes who or what is performing the action. (In the passive voice, the person or thing performing the action often does not even appear in the sentence.)

Passive

Mistakes were made by me.

Active

I made mistakes.

Often, the writer drops the by clause entirely in a passive sentence.
Subjects that act require powerful verbs that stimulate the imagination and senses.

Passive

Active
