  A bridge going from Wronskian solutions to generalized Wronskian solutions of
the Korteweg-de Vries equation is built. It is then shown that generalized
Wronskian solutions can be viewed as Wronskian solutions. The idea is used to
generate positons, negatons and their interaction solutions to the Korteweg-de
Vries equation. Moreover, general positons and negatons are constructed through
the Wronskian formulation. A few new exact solutions to the KdV equation are
explicitly presented as examples of Wronskian solutions.
