Narrative:

I was flying with instructor completing flight review preparation. Centennial tower cleared our aircraft for landing on runway 35L. After turning to base for 35L; it was determined that a king air was descending rapidly on a straight-in base approach from the southwest into our base leg for a simultaneous approach on 35R. My instructor immediately took control of the aircraft using positive exchange of controls to execute an evasive maneuver to the left and descent to avoid the other aircraft. After receiving control back of the aircraft with positive exchange of controls; I landed our aircraft safely for a full stop landing. After discussing the situation with my instructor; we determined that the near-miss was most likely caused by inadequate ATC aircraft separation; king air pilot not following ATC altitudes; or king air pilot conducting a rounded or straight-in base approach to final that cut through our base leg.
