In the previous paper (Li, X. Z., Xi, P., Zhai, X. H.: Phys. Lett. B{\bf666}, 125-130 (2008)), we show the solutions of Einstein equations with static spherically-symmetric quintessence-like matter surrounding a global monopole. Furthermore, this monopole become a black hole with quintessence-like matter and a deficit solid angle when it is swallowed by an ordinary black hole. We study its quasinormal modes by WKB method in this paper. The numerical results show that both the real part of the quasinormal frequencies and the imaginary part decrease as the state parameter $w$, for scalar and gravitational perturbations. And we also show variations of quasinormal frequencies of scalar and gravitational fields via different $\epsilon$ (deficit solid angel parameter) and different $\rho_0$ (density of static spherically-symmetric quintessence-like matter at $r=1$), respectively.
