Abstract: The semiampleness of the divisor $-(K_X+S)$ is proved for a pair $(X,S)$ with purely log terminal $\mathbb Q$-factorial singularities, where $X$ is a three-dimensional normal projective algebraic variety and $S\subset X$ is a normal surface such that the divisor $-(K_X+S)$ is nef and big.
