  The space-like penguin contributions were ignored on little ground in many
previous studies of nonleptonic B decays and CP violation. Taking the
penguin-dominated channels $B^{-} _{u}\rightarrow \bar{K}^{0}\pi$ and
$B^{-}_{u}\rightarrow K^{0} K^{-}$ for example, we illustrate the
non-negligible effects of the space-like penguin diagrams on CP asymmetries.
Some quali- tative remarks are given on the gluonic penguin picture and the
direct CP violation in exclusive two-body decays of B mesons.
