Abstract: The present paper firstly represents the model about random walks in timerandom environments on the right line, then the studies about recurrencetransience criteria and limit theorem by using some relative theo ries of Markov chains, and finally a center limit theorem of this random walks in the nonrecurrence case.

Key words: random environments, random walks, recurrence, the law of large numbers, center limit theorem
