  In this paper, we study phase diagrams of the extended Bose-Hubbard model
(EBHM) in one dimension by means of the quantum Monte-Carlo (QMC) simulation
using the stochastic-series expansion (SSE).In the EBHM, there exists a
nearest-neighbor repulsion as well as the on-site repulsion. In the SSE-QMC
simulation, the highest particle number at each site, $n_c$, is also a
controllable parameter, and we found that the phase diagrams depend on the
value of $n_c$. It is shown that in addition to the Mott insulator, superfluid,
density wave, the phase so-called Haldane insulator and supersolid appear in
the phase diagrams, and their locations in the phase diagrams are clarified.
