This paper studies the following theinitial-boundary value problem with localized reaction term:\begin{align*}u_{t}(x,t)=\Delta u(x,t)+\frac{1}{(1-u(x,t))^{p}}+\frac{1}{(1-u(x^{*},t))^{q}}, (x,t)\in B\times(0,T),\end{align*}\begin{align*}u(x,0)=u_{0}(x), \ x\in B,\end{align*}\begin{align*}u(x,t)=0, \ (x,t)\in\partial B\times(0,T),\end{align*}where $B=\{x\in \Bbb{R}^n: \|x\|<1 \}$, $\partial B=\{x\in\Bbb{R}^n: \|x\| =1\}$, $x^{*}\in B$, $00$,and $u_{0}\geq 0$. The existence and quenching behavior of theproblem are studied. For the case $x^{*}=0$, the quenching rateof solution near the quenching time is investigated.
