On the base of renewing the developing of three-shot,after analyzing the data of three-shot in the 2000-2001 season in CUBA and comparing with CBA and the world powerful teams,we could make the conclusion as follows: Three-shot plays an important role for the individual and team score as well as final result of team in CUBA.But there is the phenomenon of low level in hit rate and unsteady in application and lack of excellent athletes.Thus I advise that the team should pay great attention to the three-shot,improve the hit rate and steady of three-shot under the strong confrontation and train the more excellent athletes of three-shot.
