  In this paper we prove the algebraic-tropical correspondence for stable maps
of rational curves with marked points to toric varieties such that the marked
points are mapped to given orbits in the big torus and in the boundary divisor,
the map has prescribed tangency to the boundary divisor, and certain quadruples
of marked points have prescribed cross-ratios. In particular, our results
generalize the results of Nishinou and Siebert. The proof is very short,
involves only the standard theory of schemes, and works in arbitrary
characteristic (including the mixed characteristic case).
