Abstract：
The author presents some straightforward proofs for two comparison theorems for Green functions of Markov chains，which slightly improve the previous results by
Varopoulos[6][7],Durrett[3],and Yan and Chen [10]. A recent result by Rogers and Wiiliams[7] about Instantaneous Markov chains is also improved by using the same idea.
