Effects of long-range Coulomb interaction in one-dimensional electron systems are studied. By using a quantum Monte Carlo method, we obtain that the zero-frequency wave-number dependent charge susceptibility at quarterfilling shows both 2kF and 4kF singularities, kF being the Fermi wave munber, in c
