  We take a new approach to construct Quintessential models. With this
approach, we first easily obtain a tracker solution that is different from
those discovered before and straightforwardly find a solution of multiple
attractors, i.e., a solution with more than one attractor for a given set of
parameters. Then we propose a scenario of Quintessence where the field jumps
out of the scaling attractor to the de-Sitter-like attractor, by introducing a
field whose value changes a certain amount in a short time, leading to the
current acceleration. We also calculate the change the field needs for a
successful jump and suggest a possible mechanism that involves spontaneous
symmetry breaking to realize the sudden change of the field value.
