Use a consistent voice. To change a sentence from the passive voice to the active voice, make the subject of the sentence the performer of the action.

A shift in mood occurs when the writer moves among commands or directions; statements or questions; and wishes, suggestions, or conditions contrary to fact. Keep your goal in mind, and you need to practice, practice, practice. (The first clause is a direction, and the second is a statement.)
