The strongly correlated two-dimensional Cu0& layer is studied to identify the mechanism of possible\udpairing superconductivity. The correlative motions of 0 and Cu holes are treated by a reasonable\udmean-field theory, and we find that holes on oxygen sites couple strongly to Cu holes to form\udCu-0 spin singlet pairs, which in turn interact strongly with the Cu resonating-valence-bond state\udand lead to an effective attraction between 0 holes, which is responsible for superconductivity
