In this paper,we give a general model of random walks in time-random environment in any countable space.Moreover,when the environment is independently identically distributed,a recurrence-transience criterion and the law of large numbers are derived in the nearest-neighbor case on Z1.At last,under regularity conditions,we prove that the RWIRE {Xn} on Z1 satisfies a central limit theorem,which is similar to the corresponding results in the case of classical random walks.
