  We study the hadronic charmless two-body B decays to final states involving
pseudoscalar and vector mesons with QCD factorization approach, including the
contributions from the chirally enhanced power corrections and weak
annihilations. The CP-averaged branching ratios and CP-violating asymmetries
are given. Most of our results are in agreement with the present measurements,
but the branching ratios of some decay channels are only marginally consistent
with the experimental observations. Considering the large uncertainties, great
advances in both experiment and theory in the near future are strongly
expected.
