　　The little grey donkey himself playing drums: "it seems that I'm not able to practice when the material is also no good." So, small gray donkey will give up the practice of long-distance running.

　　小灰驴自己也打起了退堂鼓：“看来我不是当千里马的料，再练也白搭。”于是，小灰驴便放弃了练长跑。

　　The black horse wants to say: "because I believe, do anything you are not afraid of incompetence, I am afraid you have perseverance."

　　小黑马想了想说：“因为我坚信，做任何事情不怕你无能，只怕你无恒心。”
