The minute he was on, the horse begun to rip and tear and jump and cavort around, with two circus men hanging on to his bridle trying to hold him, and the drunk man hanging on to his neck, and his heels flying in the air every jump, and the whole crowd of people standing up shouting and laughing till tears rolled down.

他一骑上马背，马便乱蹦乱跳，一边绕着圈儿撩蹶子，马戏班的两个人使劲拖住马鞍子，想扶住他。那个醉鬼呢，使劲抓住了马脖子。马每跳一回，他的脚后跟便被抛向空中一回。全场观众乐得站立起来，大喊大笑，笑得眼泪直流。
